Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine harvester raising device for facilitating maintenance of a mowing device section.

[0002]

2. Description of the Related Art A combine harvester is provided with a cutting blade device, a grain stalk scraping device, a feeding device, a transport device, etc., for entanglement and clogging of grain stalks. Is likely to occur. However, since there is a grain culm raising device on the front side, it is easy to disturb the maintenance, and even if this grain culm raising device is removed, it is complicated and troublesome.

[0003]

The present invention provides a cutting blade device 1
And a grain culm raising device 5 that raises the raising tines 4 to raise the grain culm in front of the mowing frame 3 in which the grain culm scraping device 2 and the like are arranged, can be opened and closed so as to be opened forward. And a hydraulic motor M for driving the raising tine 4 is attached to the grain culvert raising device 5 to form a combine grain culvert raising device.

[0004]

[Operation and Effect of the Invention] During mowing work, the grain culm raising device 5 is fixed to the mowing frame 3 at a proper mounting position, and hydraulic pressure is sent to the hydraulic motor M to drive it. Transmit tine 4. The grain culm raised by the grain culm raising device 5 is guided by the scraping device 2 and the like, cut by the cutting blade device 1, and conveyed to the threshing device.

When the grain culvert raising device 5 is opened for maintenance of the reaping device portion, the hydraulic motor M is opened when the grain culvert raising device 5 is unfixed and the grain culvert raising device 5 is opened forward. Is also moved integrally. In this way, since the upper part of the grain culm raising device 5 is opened and closed in the front and rear direction, the front side part or the upper side part of the grain stalk scraping device 2, the cutting blade device 1 and the like located at the lower rear side of the grain culm device 5 is opened and closed during maintenance. It is widely opened for easy maintenance. Moreover, since the hydraulic motor M for driving the grain culm raising device 5 is integrated with the grain culm raising device 5, the relation with the transmission mechanism on the grain culm raising device 5 side is always constant, and the grain culm raising device 5 is Cutting frame 3 of device 5
It is possible to simplify the structure of fixing and releasing to the side and the operation.

[0006]

[Example] A combine is a self-removing type, in which a threshing device 8, a control device 9, an engine E, a grain tank 10 and the like are mounted on a chassis 7 having a crawler 6, and a cutting device is provided in front of the threshing device 8. 11 is attached. The mowing device 11 pivotally supports the upper end of the mowing frame 3 on a support frame 12 in front of the chassis 7, and is lifted and lowered with respect to the chassis 7 by a lift cylinder 14 which is hydraulically expanded and contracted. In this reaping frame 3,
A clipper type cutting device 1 in the form of a clipper extending over the cutting width is attached to the lower end part, and a scraping device 2 for scraping grain culms and a collecting device 15 for collecting the cut grain culms backward are provided above the cutting blade device 1. Etc. A weeding rod 16 protruding forward from the cutting blade device 1 and a weeding plate 17 at the front end of the weeding rod 16 are provided.

The grain culm raising device 5 includes a raising case 18 in which a chain for rotating and driving the raising tine 4 protruding in the lateral direction is stretched between sprockets in the vertical direction. Arranged at appropriate intervals along the left and right sides of the guide passage, the upper end of each raising case 18 is integrally formed with a raising frame 19 which also serves as a transmission case and extends laterally on the rear side.
Through the power transmission mechanism in the raising frame 19, each raising case is
It is a structure for transmitting a tine chain in the space 18.

The grain culm raising frame 19 is a cutting frame 3
It is provided rotatably around a lateral hinge 21 with respect to the upper end portion of the raising column 20 standing upright from both right and left sides of the raising column 20. The raising column 20 and the raising case 18 can be expanded and contracted. The damper 22 can be provided to hold the open rotation position. The weeding rod 16 has a construction in which the weeding plates 17 can be joined and separated from each other.
It is configured integrally with and is pivoted open to the front. Therefore, at the time of combine operation, the grain culm raising device 5 is attached to the hinge 21.
The swarding plate 17 is connected and fixed to the front ends of the shunting rods 16 facing each other by rotating and closing around.

The hydraulic motor M is integrally attached to the lateral end portion of the pull-up frame 19 to interlock with an internal transmission mechanism, and a hydraulic pump P driven by the engine E on the chassis 7 side. And a hydraulic hose 40 are connected between them and hydraulically interlocked. Therefore, the lift cylinder 1
4, when the harvesting device 11 is moved up and down, the grain culm raising device 5 is rotated back and forth, and the like, the hydraulic hose does not become a resistance due to the flexibility, and the resistance between the hydraulic motor and the raising frame 19 is reduced. No need to separate.

The harvesting device 11 includes a collecting device 1
A grain culm transporting device 23, which inherits and transports the harvested grain culms collected in 5, is provided above the harvesting frame 3.
This grain culm transporting device 23 uses a hinge 24 at the terminal end,
The starting end side can be vertically rotated with respect to the collecting device 15, and can be vertically rotated by the control motor 25 attached to the mowing frame 3, so that the transfer position of the grain stem can be changed. By adjusting the transfer position of the grain culms, it is possible to change the delivery position of the grain culm conveying device 23 to the feed chain 26 of the threshing device 8 to change and adjust the depth of supply of the grain culms to the handling chamber. Reference numeral 27 is a slidable rod facing the feed chain 26.

Reference numeral 28 is a handling barrel in the handling barrel chamber, 29 is a swinging sorting shelf below the threshing device, 30 is a sorting air passage, 31 is compressed air sardine, 32 is a suction dust collector, and 33 is threshed culm. An culvert device for discharging the culm, and a cutter 34 for receiving and cutting the culm. Reference numeral 35 is a cabin, and 36 is an auger for taking out grains of the Glen tank 10. When the chain of the grain culm raising tines 4 is driven by the hydraulic motor M, a relief valve is provided in the hydraulic circuit for driving the hydraulic motor M, so that when the overload occurs, the relief valve is released. -The valve can be activated to prevent damage to the transmission mechanism. or,
The setting of the raising speed of the grain culm raising tines 4 can be set to an independent speed different from the speed of the cutting blade device 1, the grain shaving device 2, etc. It is easy to widen the speed adaptation range.

In such a mowing device 11, a position sensor S is provided in the vicinity of the pivot 13 of the mowing frame 3 with respect to the support frame 12, and when the position sensor S detects that the mowing device 11 has risen to a certain position, the hydraulic pressure is increased. When the motor M is stopped and the drive of the pull-up tine 4 is stopped, and the reaper 11 is lowered to a certain position, the hydraulic motor M can be driven in a controlled manner. As a result, at the end of the mowing process, it is possible to eliminate the scratching noise caused by the drive of the raising tine 4, and it is less likely that the raising tine 4 hits the ear of the uncut grain culm at the beginning of cutting.

In FIG. 3, the difference from the above example is that the upper end side of the grain culm raising device 5 is opened forward, and can be connected to and separated from the hitch 37 of the raising column 20 of the raising frame 19. And the lower end side is hinged 3 to the front part of the weeding rod 16.
It pivots back and forth at 8. Further, in FIG. 4, hinges 39 are provided at the front and rear intermediate portions of the dividing rod 16.
