However, in the above-described conventional example, when the switch of the automatic handling depth control device (automatic handling depth switch) is turned on and the ridge cutting is performed,
There is a problem that leftovers occur. That is, when mowing at the ridge, the crawlers on one side (the ridge side) on the left and right sides of the crawler traveling device are easy to ride on the convex portion of the ridge, whereby the cutting blade is inclined left and right, and the cutting height on the left and right is not good. The length of the culm becomes uniform and the length of the culm becomes shorter (this is particularly noticeable in the case of a multiple-row combine, because the width of the mulch is wide). Can be In addition, it is necessary to take care that the divider close to the ridge does not plunge into the ridge at the edge of the ridge. For this reason, it is customary to perform the reaping work while frequently moving the pre-processing unit up and down. culms (short culm) after cutting mixed is the one in which inevitably扱残Mr. many occurs because the culms of irregular tip is conveyed mixed. For this reason, in actual work, generally, when mowing near the ridge, the handling depth automatic switch is once turned off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described with reference to an embodiment shown in the drawings. FIG. 1 is an overall plan view of the combine. In the front of the fuselage, a pre-processing unit 4 including a raising device 1, a cutting blade 2, a handling depth conveying device 3 equipped with a handling depth adjusting mechanism, and the like are provided with a hydraulic cylinder (not shown). It is mounted so that it can move up and down freely. The grain stalk a cut by the cutting blade 2 is lifted by the handling depth conveying device 3 and passed from the terminal end to the feed chain 5 of the threshing unit A. 6a, the kernels are separated and sorted out from straw and the like by a sorting unit (not shown), and then stored in a kernel tank 7. On the other hand, the culms after threshing are transported to the rear of the machine by a waste wara chain 8; They are cut by a cutter 9 or bound by a notter 10 and discharged to a field. The pre-processing unit 4 includes a direction sensor 1 provided between the left and right dividers 11 for controlling the traveling direction of the body.
2, various sensors for detecting the working state of the pre-processing unit 4, such as a main sensor 13, a tip sensor 14, a stock sensor 15, a cutting height sensor 16, and the like of a handling depth adjusting mechanism are provided. Further, a vehicle speed sensor 18 for detecting a vehicle speed is provided on the side of the main unit 17 equipped with the threshing unit A, and a detection signal of each of these sensors is supplied to a control unit 19 composed of a microcomputer arranged at an appropriate position of the main unit 17. To automatically control each drive unit such as a handling depth adjustment mechanism. In FIG. 3, reference numeral 20 denotes a manual depth switch (shallow side), 21.
Is a manual handling depth switch (deep handling side), 22 is an automatic handling depth switch, S is a reaping clutch switch, and these switches 20, 21, 22, and S are also the sensors 12, 13, and
The control unit 19 is connected similarly to 14, 15, and 16.
Reference numeral 23 denotes a handling depth limit switch (shallow handling side), 24 denotes a handling depth limit switch (deep handling side), 25 denotes a handling depth adjustment drive unit (forward / reverse rotation motor), and 26 denotes a handling depth ramp. Is also connected to the control unit 19, and the handling depth lamp 26 is disposed on the operation panel 28 in front of the driver's seat 27, and is lit continuously during automatic working of the handling depth. The above configuration is substantially the same as the conventional one.

By the way, the present invention relates to the above- mentioned manual switch for manual handling.
Switches 20 and 21 and a handling depth automatic switch 22 are provided separately.
9 is electrically connected to the handling depth adjusting drive unit (forward / reverse rotation motor) 25 via the control unit 19,
9 is turned on, the motor 25 is rotated to the deep handling side, and the handling depth transfer device 3 is brought to the deepest handling position (the position in which the culm of the harvested grain culm is pinched and transported in the direction closest to the base of the culm). It is configured to be set automatically, and to return to the automatic handling depth control when the ridge cutting switch 29 is turned off.

When the ridge cutting switch 29 is turned on, the depth lamp 26 blinks so that it can be easily distinguished from automatic depth (continuous lighting). It can prevent forgetting to press.

The control unit 19 is connected to a high-speed cutting vehicle speed control motor 30 so that when the ridge cutting switch 29 is turned on, the vehicle speed cannot be changed to the maximum speed. Clogging, automatic handling depth ON
Sometimes, the threshing load is light, so that the vehicle speed can be changed to the maximum speed. However, if the work is performed at the deepest when the ridge cutting switch is turned on, the straw part enters the handling chamber 6 too much and the amount of debris increases. The load increases, and if the work is continued in this state, the engine output decreases as the gear shifts to the higher speed side, and the rotation of the threshing unit and the sorting unit may decrease, resulting in poor sorting. Therefore, the speed can be changed only up to the vehicle speed at which the engine does not go down (depending on the model, horsepower, etc.).

In the above arrangement, when cutting the culm at the ridge, as shown in the flowchart of the ridge control operation in FIG.
Irrespective of the state of the motion switch 22,
Switch 22 is in the ON state and also in the OFF state
Is automatically set to the deepest threshing posture driver for threshing depth adjustment of the threshing depth conveying device 3 (forward and backward rotation motor) 25 is rotated in the depth扱側is threshing depth conveying device 3 . Therefore, even if the harvested grain culm is sent to the handling depth conveying device 3 with the ears uneven, the harvested grain culm is in the deepest handling state and the feed chain 5 of the threshing unit A
Will be relayed to the side. As a result, the grain stalk a is deeply penetrated into the handling chamber 6 and is subjected to the shedding effect of the handling drum 6a, so that the unhandled amount is reduced as much as possible. Also, when the ridge cutting switch 29 is turned on, the vehicle speed is controlled by the vehicle speed control motor 30 and the high speed side is cut off. Even if you work at the deepest during mowing along the ridges, the rotation of the threshing unit and the sorting unit will go down, causing poor sorting There is no danger that the engine will stop.
