Abstract

PROBLEM TO BE SOLVED: To provide a measure for preventing a danger when a transverse auger is rotated in the case of zoom stretching of a zoom auger. SOLUTION: This apparatus for discharging grains is obtained by controlling the turning peripheral speed of the tip of a transverse auger 12 so as to be constant regardless of the extent of the stretching of the transverse auger 12 in the apparatus for discharging the grains comprising the transverse auger 12 stretchable in the shaft direction, capable of conveying the grains in the transverse direction, discharging the grains from the tip thereof and connected to a vertical auger turnable around the central shaft and capable of conveying the grains in the vertical direction. Since the turning peripheral speed (moving speed) of the tip of the transverse auger 12 is not increased without regard to the extent of the stretching of the transverse auger 12, the turning peripheral speed is not increased even when zoom stretching of the transverse auger 12 is carried out. Thereby, the maloperation by an operator is eliminated. Furthermore, even when the operator is situated near a remote control panel to perform operation, the turning peripheral speed of the transverse auger 12 is constant due to no turning at a high speed. As a result, a danger of collision of the transverse auger 12 with the operator by an unexpected high-speed turning is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain discharging device such as a combine or a grain carrier.

[0002]

2. Description of the Related Art A conventional grain discharge device for a combine, as disclosed in the prior invention (Japanese Patent Application Laid-Open No. 9-54) of the present applicant, is provided with a grain tank 9 for temporarily storing grains, as shown in FIG. A bottom auger 9a for transferring grains in a horizontal direction at a bottom portion, a vertical auger 11 which is connected to the bottom helix 9a, transports grains in a vertical direction, and is rotatable around a vertical axis; A grain discharging auger 10 is provided, which comprises a horizontal auger 12 which conveys grains in the horizontal direction in connection with the horizontal auger 12 and which is vertically movable up and down and zoomable in the longitudinal direction. The auger outlet 19 is located at a position where the grain is to be discharged during the dumping operation.
Swivel the vertical auger 11 and place the horizontal auger 1
2 and the horizontal auger 12 is zoomed in or out or zoomed out. Also, when harvesting work or running on a road is not performed, the horizontal auger 12 is zoomed out to reduce the auger receiver 40 on the combine 1. To sit and store.

[0003]

In the combine 1, when cutting, threshing, or traveling on a road other than in the threshing operation, as shown by the reference line in FIG. The lateral auger 12 is seated on the auger receiver 40 on the upper part of the vehicle body 6 and stored, thereby preventing the auger 10 from shaking, vibrating or falling off during a mowing operation. The danger of the part projecting beyond the combine 1 is prevented. And grain is stored in the Glen tank 9,
In the case of performing the threshing, after the combine 1 is moved to the vicinity of the grain carrier, the horizontal auger 12 of the auger auger 10 is separated from the auger receiver 40, raised, swirled or extended, and the auger discharge port 19 is set to the grain. The grain dumping operation is performed by facing the opening of the grain carrier.

The horizontal auger 12 of the combine 1 shown in FIG.
The upper tube 1 has a narrow gap outside the middle tube 15 containing a spiral 17 for carrying out a grain transport operation.
6 is fitted, and the upper tube 16 is loosely fitted to the middle tube 15 slidably in the axial direction.
Hereinafter, the middle tube 15 and the upper tube 16 are collectively referred to as a zoom cylinder. The horizontal auger 12 is capable of performing a so-called zoom action that can be extended and contracted by a zoom cylinder.

[0005] The operation of the combine 1 in which the horizontal auger 12 can be extended and contracted by the zoom action, and the threshing operation are significantly easier than a fixed-length horizontal auger without the zoom action. That is, in the case of a fixed-length horizontal auger, the stop position of the combine 1 and the turning angle of the vertical auger 11 are adjusted in order to align the auger discharge port 19 at the tip of the horizontal auger 12 with the opening of a grain container or the like. Had to be done with adjustments.

[0006] Therefore, the stop position of the combine 1 must be determined quite strictly, the driving operation requires considerable skill, and the operation time for adjustment often becomes long. However, the dumping auger 10 having the horizontal auger 12 having the zooming function adjusts the length of the horizontal auger 12 by the zooming operation and the turning of the vertical auger 11 so that the auger outlet 19 at the tip of the horizontal auger 12 can be moved. Since the position can be largely changed and adjusted, the stop position of the combine 1 does not need to be strictly determined, and the stop operation for positioning becomes extremely easy.

Since the turning motor 11a of the vertical auger 11 for turning the horizontal auger 12 rotates at a constant speed, the turning angular speed of the horizontal auger 12 is constant, and the peripheral speed (moving speed) of the fixed length horizontal auger tip is always constant. Constant speed. However, in the horizontal auger 12 which can be expanded and contracted by the zoom action, the turning motor 11a rotates at a constant speed. (Moving speed) increases or decreases. In particular, when the zoom auger is zoom-expanded, the peripheral speed (moving speed) of the distal end of the horizontal auger 12 increases, so that the operator who operates the remote operation panel near the distal end of the horizontal auger 12 performs the operation. Not only is it difficult, but unexpected high-speed movement can cause dangerous work, such as the tip of the auger 10 colliding with the operator.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a measure for preventing danger when the horizontal auger turns when the zoom auger is zoomed.

[0009]

The above object of the present invention is attained by the following constitution. In other words, a vertical auger that can rotate around the central axis and transports the grain in the vertical direction is connected to a horizontal auger that can transport the grain in the axial direction and transport the grain in the horizontal direction and discharges the grain from the tip. In the grain transfer device
A grain conveying device provided with control means for controlling a turning peripheral speed of a tip portion of the lateral auger to be substantially constant irrespective of an amount of expansion and contraction of the lateral auger.

[0010] Regardless of the amount of expansion and contraction of the lateral auger, the turning peripheral speed (moving speed) of the tip portion of the lateral auger is not increased, so that even if the horizontal auger is zoomed, the turning peripheral speed does not increase. The operator does not operate erroneously. Also, even when the operator operates near the remote operation panel, since the turning peripheral speed of the lateral auger is constant and does not turn at high speed, there is a danger that the horizontal auger will collide with the operator due to unexpected high speed turning. Disappears.

Is set, and the extension length of the horizontal auger 12 is set by the zoom setting dial 141. When the automatic extension switch 112 is turned on after the setting is completed, the dumping auger 10 automatically moves to the set position according to the command stored in the CPU 101 and the set value of the setting dial. That is, first, the ascending relay 160 is operated to disengage the lateral auger 12 from the auger receiver 40 and ascend from the broken line in FIG. 4 to the solid line. Next, the right turn relay 162 or the left turn relay 16 is turned up to the turning angle set on the overhang setting dial 140.

The horizontal auger 12 is turned. The output signal of the turning angle sensor 151 detects that the lateral auger 12 has reached the set turning angle, and ends the turning. During this time, the augmenting / retracting motor 50 is driven by operating the zoom extension relay 166 to the extension length set on the zoom setting dial 141, and the horizontal auger 12 is extended. The output signal of the zoom length sensor 152 detects that the horizontal auger 12 has reached the set length, and ends the zoom expansion.

When the automatic storage switch 113 is turned on, C

That is, first, the ascending relay 160 is operated to drive the linear actuator 14, and the lateral auger 12 is elevated to a safe height (solid line in FIG. 4). Next, the right turn relay 162 or the left turn relay 163 is operated to the position above the auger receiver 40 to turn the turning motor 11a.
To rotate the horizontal auger 12. According to the output signal of the turning angle sensor 151, the horizontal auger 12

During this time, the zoom shortening relay 167 is operated to drive the auger extension / retraction motor 50 to shorten the horizontal auger 12, and the output signal of the shortening limit switch 127 is used to output the horizontal auger 1.
The zoom shortening of 2 is ended. Finally, the descending relay 161
, The linear actuator 14 is shortened, the lateral auger 12 is stored in the auger receiver 40 (see FIGS. 2 and 3), the operation of the auger receiver seating limit switch 125 is confirmed, and the automatic storage ends.

After the manual or automatic setting of the position of the auger discharge port 19 of the horizontal auger 12 is completed, the dumping operation switch 1
When 10 is turned on, the grain discharging clutch relay 170 operates to start the grain discharging operation, and the transport of the grains in the Glen tank 9 is started. When the husking stop switch 111 is turned on,
The operation of the dumping clutch relay 170 is stopped, and the dumping operation is stopped. The halt operation of the husking operation can also be performed by manually operating the husking clutch lever 3 (see FIG. 4) provided in the cockpit 2. The operating state of the husking clutch lever 3 is detected by the husking clutch lever sensor 153. Can be detected.

A remote operation panel switch 131 is provided near the front end of the horizontal auger 12.
30 (see FIGS. 1 and 3). The operator operates the remote operation panel switch 131 near the tip of the horizontal auger 12 to operate the manual operation of the horizontal auger 12 in substantially the same manner as described above. , Turning right, turning left, extending, shortening, threshing operation, stopping and automatic storage.

In the embodiment of the present invention, when the right or left turning operation is performed in a state where the horizontal auger 12 is extended, the turning peripheral speed v (m / s) of the tip of the horizontal auger 12 is performed.
Is controlled to be constant regardless of the extension length L (m) of the horizontal auger 12. That is, v = Lω / 2π = C = constant (1) ω = 2πv / L = C ′ / L (2) where ω is a turning angular velocity (rad / s). FIG.
, When the length of the lateral auger 12 is L1, L2, L3, ω1 = 2πv / L1 = C ′ / L1 ω2 = 2πv / L2 = C ′ / L2 ω3 = 2πv / L3 = C ′ / L3.

The control device 100 includes a manual right turn switch 1
16, when a turning signal is input from the manual left turning switch 117, the remote operation panel switch 131, or the like, the detection value of the zoom length sensor 152 is fetched, and (1),
By performing the calculation of (2), the right turning relay 162 or the left turning relay 163 is driven to designate the turning direction, and the turning motor 11a is turned by the turning motor rotation speed adjusting means 164.
The rotation of FIG. 4 is controlled. The turning motor rotation control means 164 performs duty control when the turning motor 11a is a DC motor, and performs pulse control when the turning motor 11a is a pulse motor, and is suitable for the type of the turning motor 11a.

Conventionally, in the dumping auger 10 capable of zoom expansion, the rotation motor 11a rotates at a constant speed, and the horizontal auger 12 rotates at a constant rotation angular velocity regardless of the length of the zoom length, and the zoom expansion is performed. Since the turning peripheral speed at the tip of the lateral auger 12 becomes larger as the zoom extension length is longer, the turning peripheral speed is too fast and the operator may perform an erroneous operation. There is a danger of colliding with the lateral auger 12 turning at a high speed when operating in a position.

However, in the embodiment of the present invention, the rotation length of the turning motor 11a is adjusted by detecting the zoom length of the horizontal auger 12, and the turning peripheral speed of the tip of the horizontal auger 12 is adjusted to the zoom extension length. Is controlled so as to be constant regardless of the length of the horizontal auger. Therefore, even if the horizontal auger 12 is zoom-extended, the turning peripheral speed does not increase, so that the operator does not operate erroneously. In addition, even when the operator operates in the vicinity of the remote operation panel 130, since the turning peripheral speed of the lateral auger 12 is constant and the turning is not performed at a high speed, the horizontal auger 12 is not provided to the operator by unexpected high-speed turning. There is no danger of collision.

In the above-described embodiment, the zoom length is continuously detected, and the rotation speed of the rotation motor 11a is continuously changed to control the rotation peripheral speed of the lateral auger to be strictly constant. Although the configuration has been described, the configuration in which the zoom length is detected as a plurality of stages, and the rotation speed of the rotation motor 11a is adjusted in a stepwise manner to control the rotation peripheral speed of the lateral auger to be substantially constant is also described above. It is possible to obtain substantially the same effect as.

FIG. 11 shows a modification of the embodiment of the present invention shown in FIGS. FIG. 11 is a side view of the combine and the grain transport vehicle illustrating the operation of the present example. According to this example, it is possible to reduce the driving power of the auger extension / contraction motor 50 when shortening the horizontal auger 12, and to prevent malfunction when the horizontal auger 12 is shortened.

The horizontal auger 12 that has been zoom-extended, such as when the grain has been conveyed from the combine 1 to the grain transport vehicle,
Will be described. In this example, when the manual shortening switch 119 is turned on, first, the raising relay 160 is operated to raise the lateral auger 12. After the horizontal auger 12 rises for several seconds, the zoom reduction relay 167 of the horizontal auger 12 is turned on to drive the auger expansion / contraction motor 50, and the zoom is reduced until the reduction switch 119 is turned off or the reduction limit switch 127 is turned on. Relay 1
By operating the auger telescopic motor 50 by operating the 67,
The horizontal auger 12 is shortened. Turn off the shortening switch 119
Alternatively, if the shortening limit switch 127 is turned on even if the shortening switch 119 is not turned off, the operation of the shortening relay 167 is stopped and the auger extension / retraction motor 50 is stopped.

The ascent of the auger is continued until the ascending limit switch 120 is turned on. When the ascending limit switch 120 is turned on, the operation of the ascending relay 160 is stopped, and the shortening switch 119 is turned on once. Even if the horizontal auger 12 is not raised, the operator manually raises the horizontal auger 12 for several seconds and then turns on the shortening switch 119 again to operate the zoom shortening relay 167 for the first time to drive the auger extension motor 50. Subsequently, the horizontal auger 12 may be shortened.

That is, in the side view shown in FIG.
When the grain transfer by the auger auger 10 is performed at the position of the horizontal auger 12 indicated by the reference line and the operation is completed, and the zooming of the auger auger 10 is shortened, the horizontal auger is moved to the position indicated by the solid line in FIG. 12 is controlled so as to be raised, and then zoom is shortened.

According to this embodiment, the driving power of the auger extension / retraction motor 50 required for the shortening operation of the horizontal auger 12 is the horizontal auger 1
Since the horizontal auger 12 is smaller when it is in the raised position than when it is in the horizontal position, by performing control to reduce the zoom after raising the horizontal auger 12, the auger telescopic motor 50 is controlled.
Thus, the required driving power is reduced, the consumption of a driving power supply battery (not shown) of the auger expansion / contraction motor 50 is reduced, and a voltage drop can be prevented. Further, as shown by the reference line in FIG. 11, when the lower side of the horizontal auger 12 is brought into contact with the container at the point A during the grain conveyance, if the zoom is shortened as it is, the leading end of the horizontal auger 12 can be obtained. There is a danger that the auger discharge port 19 projecting downward from the part may collide with the side wall of the container. However, by performing control to shorten the zoom after raising the horizontal auger 12, the auger discharge port 19 and the side wall of the container can be connected. The effect of avoiding the danger of collision is also obtained.

Next, another modified example of the embodiment of the present invention shown in FIGS. 1 to 10 is shown in FIG. FIG. 12 is a top view of the combine showing the operation of the present embodiment. According to the present embodiment, the operation of extending and storing the horizontal auger 12 can be easily performed.

The combiner 1 shortens the dumping auger 10 when performing harvesting work in the field, stores it in the auger receiver 40, performs the work, and discharges the grains from the Glen tank 9 when combining. After moving 1 to the vicinity of the grain transport vehicle, the dumping auger 10 is released from the stored state of the auger receiver 40, extended, zoom-expanded, and the grain transport operation is performed. For this reason, in the combine 1, it is necessary to perform the shortening storage and the extension of the auger auger 10 every time the harvesting operation and the grain transport operation are switched, thereby facilitating the operation and reducing the time required for the operation. It is desired.

In this embodiment, in the grain discharging auger 10 capable of zooming and extending the horizontal auger 12, the speed at which the horizontal auger 12 is shortened is lower than the speed at which the horizontal auger 12 is extended and the turning speed from the grain discharge position to the auger storage position. It is characterized in that the control is performed to increase the speed.

That is, in the overhang operation of the horizontal auger 12, first, the manual lifting switch 114 is operated to raise the horizontal auger 12 to a safe height and separate from the auger receiver 40, and then the manual right turning switch 116 is operated. By operating the horizontal auger 12, the turning is started from the point C with the turning point at the point B (see FIG. 12). At the same time, the user operates the manual extension switch 118 to start extending the horizontal auger 12. If the manual expansion switch 118 is not operated, zoom expansion is not performed.
The length between -C does not change, and the trajectory of the tip of the lateral auger 12 follows the arc CD shown by the solid line in FIG.
When the manual extension switch 118 is operated at the same time, the horizontal auger 12 zooms and expands while turning. However, since the zoom expansion speed in this example is smaller than the zoom reduction speed, the locus of the tip of the horizontal auger 12 is used. Follows the reference line CE of FIG. After the tip of the lateral auger 12 reaches the point E and completes turning, a manual extension or manual shortening operation is performed if necessary, for example, to position the tip of the horizontal auger 12 at the point F.

The work at the point F is completed, and the horizontal auger 12
Is stored, first, the manual augment switch 114 is operated to raise the lateral auger 12 to a safe height, and then the manual left turning switch 117 and the manual shortening switch 119
Operate at the same time. The trajectory of the tip of the lateral auger 12 is shown in FIG.
When the vehicle turns along the reference line FC of No. 2 and the zoom shortening speed is higher than the extension speed, the turning operation of the horizontal auger 12 is completed when the vehicle turns to the point C of the storage position. By operating the manual lowering switch 115 at the point C,
When the horizontal auger 12 is lowered and seated on the auger receiver 40, the storing operation is completed.

In this example, since the speed of the zoom extension of the horizontal auger 12 is reduced, even if the auger extension is started at the same time as turning when the lateral auger 12 is extended, the amount of extension of the auger becomes full when the turning is completed. It is near the middle of the amount of extension, and after turning is completed, the amount of extension of the auger can be adjusted to match the opening of the container that receives the grain, so the operation is safe, the risk of erroneous operation is small, and during turning, Compared to the control to start zoom extension after turning without zoom extension,
The time required for positioning the tip of the horizontal auger 12 can be reduced. In addition, since the speed of zoom reduction of the horizontal auger 12 is increased, when the horizontal auger 12 turns to a position above the auger receiver 40 during storage, since the shortening operation of the horizontal auger 12 has been completed, the user can immediately turn the auger receiver 40 toward the auger receiver 40. It can be stored quickly, so that it can move to the next harvesting work immediately.

The operator operates the remote operation panel 1
For example, when the user stands close to 30 and operates the adjustment of the position of the auger discharge port 19 while monitoring the threshing condition, the above-mentioned control for shortening the expansion / contraction speed of the horizontal auger 12 and decreasing the expansion speed is performed. In the configuration to be performed, erroneous operation due to different expansion and contraction speeds and unexpected auger discharge 1
Since there is a danger due to the high-speed movement of the horizontal auger 9, it is possible to adopt a configuration in which the control can be switched to a control that makes the expansion and contraction speeds of the horizontal auger 12 the same.

Next, still another modification of the embodiment of the present invention shown in FIGS. 1 to 10 is shown in FIG. FIG. 13 is a top view of the combine 1 showing the operation of this embodiment. According to this embodiment, the operation of extending and storing the horizontal auger 12 is automatically extended and automatically stored to further facilitate the operation.

In the present embodiment, a waste auger 10 for expanding and shortening the zoom, which can control the extension and storage of the lateral auger 12 with an automatic switch, the amount of zoom extension at the time of turning completion in the automatic extension. Is controlled so as to reduce the total zoom amount of the zoom setting dial 141 to about one half of the preset amount.

When the overhang setting dial 140 and the zoom setting dial 141 are set and the automatic overhang switch is turned on (see FIG. 9), the horizontal auger 12 rises to a safe height, and as shown in FIG. Starts turning from point C around the turning center. If the zoom extension is set to zero with the zoom setting dial 141, the length between B and C does not change,
The trajectory of the tip of the lateral auger 12 extends along the arc CD shown by the solid line in FIG.
In the case of F, the trajectory of the tip of the horizontal auger 12 projects along CE ′ shown by the reference line in FIG. Here, the length DE ′ is about one half of the length DF. Horizontal auger 1
After the tip of No. 2 reaches the point E ', the zoom is further extended, and the tip of the horizontal auger arrives at the point F to terminate the automatic overhang. After the tip of the lateral auger 12 reaches the point E ', it is possible to perform a manual extension or manual shortening operation. F
When the point is completed and the automatic storage is performed, use the horizontal auger 12
The trajectory of the tip portion of FIG. 13 turns following the reference line F-C shown by the reference line in FIG. 13, and the shortening operation of the lateral auger 12 is completed at the point C at the storage position. At the point C, the horizontal auger 12 descends and sits on the auger receiver 40 to complete automatic storage.

In this example, when the horizontal auger 12 is extended by automatic extension, auger extension is started at the same time as turning, but the augment amount of the auger at the time of completion of turning is determined by the total extension amount set by the zoom setting dial 141. Since the control is performed so as to be reduced to half, the extension of the auger can be further adjusted after the turning is completed, so that the auger can be adjusted to the opening of the container for receiving the grain.

For this reason, the operation is safe, there is little danger of erroneous operation, and zooming is not performed during turning, and it is necessary to position the tip of the lateral auger 12 as compared with the case where expansion is started after turning is completed. Time can be shortened.

When the horizontal auger 12 is pivoted above the auger receiver 40 during automatic storage, the horizontal auger 12
Is controlled to end the shortening operation of the horizontal auger 1
2 can be immediately lowered toward the auger receiver 40, can be stored promptly, and can immediately proceed to the next harvesting operation.

When there is no obstacle between the combine 1 and the grain transport vehicle and it is desired to reduce the time required for unloading the grain, the turning of the horizontal auger 12 at the time of automatic overhang is started. At the same time, the automatic extension of the horizontal auger 12 is started, and the trajectory of the tip of the auger shown in FIG.

In the above-described control for performing the zoom extension while the horizontal auger 12 is turning, particularly when the horizontal auger 12 passes above the cockpit 2, the operator's monitoring tends to be insufficient, and the horizontal auger 12 may be obstructed. Since contact or collision with an object is likely to occur, the zoom extension of the horizontal auger 12 is stopped until the horizontal auger 12 passes above the cockpit 2, and the horizontal auger 1 is stopped.
It is also possible to adopt a configuration in which control for starting the zoom extension after the vehicle 2 turns and passes above the cockpit 2 can be selected.

Further, when there is an obstacle between the combine 1 and the grain carrier, for example, in order to avoid contact and collision between the dumping auger 10 and the obstacle during automatic overhang,
The trajectory of the auger tip shown in FIG. 13 is shown as CD, while the expansion of the horizontal auger 12 is stopped during the turning of the horizontal auger 12, and the trajectory of the auger tip is shown as DE'-F after the turning is completed. It is also possible to adopt a configuration in which the control for expanding the zoom can be selected.

When there is an obstacle between the combine 1 and the grain carrier, in order to avoid contact and collision between the dumping auger 10 and the obstacle at the time of automatic overhang, first, the auger receiver 40 is used.
After the horizontal auger 12 is lifted off from, the horizontal auger 12 continues to be lifted, does not rotate while the horizontal auger 12 is rising, performs only the zoom extension, and automatically extends after the zoom extension is completed. For starting the turning of the horizontal auger 12 can be selected.

Next, still another modification of the embodiment of the present invention shown in FIGS. 1 to 10 is shown in FIGS. FIG. 14 is a diagram showing a flow of control at the time of zoom expansion in this example, and FIG. 15 is a diagram showing a flow of control at the time of zoom reduction in this example. According to this example, it is possible to prevent damage to the auger expansion / contraction motor and the auger component due to the contact of the horizontal auger 12 with an obstacle or the like at the time of extension and the clogging of the residual grain at the time of shortening.

In the present example, the auger telescopic motor 50 for extending or shortening the auger 10 in which the horizontal auger 12 can be manually and automatically extended, and can be manually shortened and automatically stored, which is a dumping auger 10 for expanding and shortening the zoom. The drive current of the auger telescopic motor 50 of the horizontal auger 12 is stopped when the drive current exceeds a predetermined value and the state of the drive current exceeds a set time. I do.

First, the operation when the horizontal auger 12 is extended will be described with reference to FIG.
This will be described with reference to FIG. Manual extension switch 118 is ON
If so, the zoom extension relay 166 is turned on. Then, if the manual extension switch 118 is not OFF and the extension limit switch 126 is not ON, the auger extension motor 50
When the motor overcurrent continues beyond the set time, the zoom extension relay 166 is turned off.
Change to F. When the manual extension switch 118 is OFF and the extension limit switch 126 is ON, the zoom extension relay 166 is turned OFF. If the auger extension / retraction motor 50 is not overcurrent and the duration time does not exceed the set time even if it is overcurrent, the zoom extension relay 16
6 is ON, and the extension operation is continued. If the automatic extension switch 112 is ON, the zoom extension relay 166 is turned off.
N, the detection value of the zoom length sensor 152 is read, and if the zoom length has not reached the set value of the zoom setting dial 141 and the extension limit switch 126 is not ON, the overcurrent setting of the auger expansion / contraction motor 50 is performed. The time is read, and if the motor overcurrent continues beyond the set time, the zoom extension relay 166 is turned off. When the zoom length exceeds the set value of the zoom setting dial 141 and when the extension limit switch 126 is ON, the extension relay 166 is turned OFF. Auger telescopic motor 50
Is not an overcurrent, and even if it is an overcurrent, if the duration does not exceed the set time, the extension relay 166 is turned ON and the extension operation is continued.

Next, the operation of the horizontal auger 12 when shortened will be described with reference to FIG.
This will be described with reference to FIG. Manual shortening switch 119 is ON
If so, the shortening relay 167 is turned on, and then, if the manual shortening switch 119 is not OFF and the shortening limit switch 127 is not ON, the overcurrent setting time of the auger telescopic motor 50 is read, and the motor overcurrent indicates the setting time. If the operation continues beyond the limit, the zoom shortening relay 167 is turned off. When the manual shortening switch 119 is OFF and the shortening limit switch 127 is ON, the zoom shortening relay 167 is turned OFF. Auger telescopic motor 50
Is not an overcurrent, and even if it is an overcurrent, if the duration does not exceed the set time, the zoom shortening relay 167 is turned off.
As N, the shortening operation is continued. Automatic storage switch 11
If 3 is ON, the zoom shortening relay 167 is turned ON,
If the shortening limit switch 127 is not ON, the overcurrent setting time of the auger expansion / contraction motor 50 is read, and if the motor overcurrent continues beyond the setting time, the zoom shortening relay 167 is turned OFF. Shortening limit switch 127
Is ON, the zoom shortening relay 167 is turned OFF. If the auger telescopic motor 50 is not overcurrent and the duration does not exceed the set time even if it is overcurrent,
The zoom shortening relay 167 is turned on to continue the shortening operation.

According to this example, when the horizontal auger 12 comes into contact with an obstacle or the like during zooming in and out, and when the kernel remains in the horizontal auger 12 during shortening and the grain is clogged due to the shortening. Since it detects that the drive current of the auger telescopic motor 50 continues to be an overcurrent and turns off the relay, the auger telescopic motor 50 is stopped, and the helix in the lateral auger 12 is stopped. The auger extension motor 50 and the auger components such as the spiral can be prevented from being damaged.

In the control flow of FIGS. 14 and 15, the auger telescopic motor rotation speed low setting time is read instead of the auger telescopic motor overcurrent setting time, and if the motor rotation speed low continues beyond the set time, A configuration in which the relay is turned off and the auger extension / retraction motor 50 is stopped may be configured.

Also in this case, since the operation is performed by detecting that the rotation speed of the auger extension / retraction motor 50 is reduced due to the resistance of an obstacle or the like, the same operation and effect as those of the above-described example can be exhibited.

In the control flow of FIGS. 14 and 15, the auger expansion / contraction set time is read instead of the auger expansion / contraction motor overcurrent set time, and the time from when zoom expansion is started until the expansion limit switch 126 is turned ON. When the time from the start of the time or zoom shortening to the time when the shortening limit switch 127 is turned on exceeds the set time, the zoom extending relay 166 is extended during extension, and the zoom shortening relay 167 is extended during shortening. May be turned off to control the auger extension / contraction motor 50 to stop. In this case, the operation is performed by detecting that the auger expansion / contraction time is prolonged due to the resistance of an obstacle or the like, and the same operation and effect as in the above-described example can be exhibited.

In the control flow shown in FIGS. 14 and 15, when the auger expansion / contraction motor overcurrent set time is exceeded and the number of revolutions is reduced, the zoom extension relay 166 or the zoom reduction relay 167 is turned off and the auger expansion / contraction motor 5 is turned off.
0, the zoom shortening relay 167 is operated during extension, and the zoom extension relay 166 is operated only for a short time during shortening.
May be configured to perform control to rotate the motor several times in reverse. In this case, by rotating the auger telescopic motor 50 in a reverse direction for a short time, the contact portion between the horizontal auger 12 and the container, and the grain lock portion in the horizontal auger 12 are released, so that the same operation as in the above-described example is performed. In addition to the operation and effect of the above, the effect that the contact portion and the lock portion are eliminated and the drive mechanism and the like are not forced to stay on can be obtained.

Next, still another modification of the embodiment of the present invention shown in FIGS. 1 to 10 is shown in FIGS. FIG. 16 is a partial cross-sectional view taken along the line GG of FIG. 4, and a side view of the turning brake of the dumping auger 10 of this example. FIG. 17 is a partial cross-sectional plan view taken along the line HH of FIG. 16. It is. In this example,
While the kernel is being conveyed by the auger auger 10, the auger auger 10 is prevented from arbitrarily turning due to the slope and the weight of the kernel.

Referring to FIG. 4, FIG. 16 and FIG. 17, the vehicle body 6 (FIG. 4) near the base of the vertical auger 11 will be described.
In this case, a turning motor 11a is fixed to the Glen tank 9), and the turning force of the turning motor 11a is meshed with a turning pinion 11b mounted on the rotation shaft of the turning motor 11a.
The turning gear 11c is fixed to the vertical auger 11 to rotate the vertical auger 11 and the horizontal auger 12 connected to the vertical auger 11, but the brake unit 60 is fixed to the vehicle body 6 side. A partial arc-shaped brake plate 65 having a thickness t is fixed to the side surface of the revolving gear 11c in a protruding state. The brake unit 60 includes a cylinder 61a at the lower end side of the cylindrical boss 61, a piston pin 62 slidably fitted with a cylinder 61a, a female screw 61b at the upper end side of the inner surface, and a pressing bolt 63 screwed therein. A pressing spring 64 is interposed in a cylinder 61a between the pressing bolt 63 and the pressing cylinder 63. The lower end of the piston pin 62 contacts the side surface of the turning gear 11c or the brake plate 65, and
Slides due to the turning of.

In this example, the braking force generated by the sliding friction between the lower end of the piston pin 62 and the side surface of the revolving gear 11c due to the pressure of the piston pin 62 is adjusted by adjusting the pressing bolt 63, and the discharging auger 10 is further reduced. A partial arc-shaped brake plate 65 is provided, which protrudes and is fixed by a thickness t corresponding to the discharge position where the turning is performed and discharges, so that the pressing spring 64 is compressed by the thickness t of the brake plate 65 at the discharge position,
Operate to increase braking force. This configuration has a simple structure in which the electromagnetic brake is not provided to the turning motor 11a, but does not increase the power load of the turning motor 11a except for the discharging position of the grain discharging auger 10, and the braking force is not increased at the discharging position of the grain discharging auger 10. Even if the load is increased and the transported weight of the sloping ground or the grain is loaded, the dumping auger 10 does not turn without permission.

Next, still another modification of the embodiment of the present invention shown in FIGS. 1 to 10 is shown in FIGS. FIG. 18 is a partial cross-sectional view taken along the line GG of FIG. 4 and a side view showing the turning brake 70 of the dumping auger 10 of the present embodiment.
9 is a partial cross-sectional side view taken along line JJ of FIG. According to this example, it is possible to prevent the dumping auger 10 from arbitrarily turning when the kernel is transported by the dumping auger 10 on an inclined land.

In this example, the vehicle body 6 near the base of the vertical auger 11
(Glen tank 9 in FIG. 4), a turning motor 11a is fixed, and the turning force of the turning motor 11a is transmitted to a turning gear 11c meshing with a turning pinion 11b mounted on a rotation shaft of the turning motor 11a. In a configuration in which the vertical auger 11 and the horizontal auger 12 connected to the vertical auger 11 are swung by being fixed to the auger 11, a brake unit 70 is fixed to the vehicle body 6 side. The brake unit 70
The inner surface of the cylindrical boss 71 is a cylinder 71a. A piston pin 72 is slidably and loosely fitted to the lower end, and a pressing piston 73 is slidably loosely fitted to the upper end. Piston pin 7
A pressing spring 74 is provided in the cylinder 71a between the upper end of the cylinder 2 and the lower end of the pressing piston 73.

The cam 75 contacts the upper end of the pressing piston 73. The cam 75 rotates about a cam shaft 75 a and is fixed to a weight arm 76 that is suspended in an L-shape, and a weight 77 is fixed to a lower end of the weight arm 76. The lower end of the piston pin 72 slides in contact with the side surface of the turning gear 11c.

In this example, when the combine 1 is stopped on the sloped land to perform the work of discharging the grain, the brake unit 70
The brake force is increased by the action of (1) to prevent unnecessary turning of the dumping auger 10 on the slope.

That is, when the combine 1 is stopped on the slope and the vertical auger 11 is inclined from the vertical position, as shown by the reference line in FIG.
6 hangs in the direction of action of gravity, so that the cam 75 rotates. The shape of the cam 75 is a shape that strongly presses the pressing piston 73 by the rotation of the cam. The pressing piston 73 presses the piston pin 72 via the pressing spring 74, and the side surface of the revolving gear 11c of the piston pin 72. The contact force, ie, the braking force, is increased. Weights other than sloping land are 7
7 and the weight arm 76 as shown in FIG.
The cam 75 does not rotate as shown by the solid line in FIG. Since the shape of the cam 75 is such that it hardly presses the pressing piston 73 when the cam 75 does not rotate, the pressing force of the piston pin 72 via the pressing spring 74 is weak, and the pressing force against the side surface of the revolving gear 11c is weak. The contact force, that is, the braking force, also decreases. According to this example, when the combine 1 is stopped on the sloped land to perform the dumping operation, the brake unit 70 automatically increases the braking force, and the dumping auger 10 is loaded with the transported weight of the kernels. In this case, the dumping auger 10 does not turn on its own, and the braking force is weak on areas other than the slopes, so that the required power of the turning motor 11a does not increase.

If a plurality of brake units 70 are provided and arranged so as to act in different directions of inclination, the above-described effect can be exhibited even if the combine 1 is inclined and stopped in any direction. it can.

Further, as shown in FIG. 9, the CPU 101 stores the detected value of the turning angle sensor 151 during the discharge of the grain of the grain discharging auger 10 in place of the configuration in which the brake unit 60 or 70 is provided. When the detected value of the turning angle sensor 151 changes while the grain is being discharged and the turning operation is not performed, the turning motor 11a is slightly adjusted until the detected value of the turning angle sensor 151 stored beforehand is obtained. It is also possible to adopt a configuration for performing control for rotation.
