Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a support device for a waste straw processing device that binds, shreds, or collectively discharges waste straw discharged from a combine harvester that reaps and threshes grain culms.

(b) Conventional technology Conventionally, a threshing device was mounted on the base of a combine harvester.
A support device is already known which rotatably supports the waste straw processing device by attaching the waste straw processing device to the rear of the threshing device and allowing maintenance and inspection of the sorting section of the threshing device from the dust outlet.

(c) Problems to be solved by the invention The straw disposal device in the known combine harvester is usually extremely heavy, and a separate strong support is erected on the machine base to support it rotatably. As a result, there were problems such as a significant increase in cost, the need for space to stand up, and an increase in the size of the aircraft.

(d) Means for solving the problems The present invention provides a combine harvester in which a threshing device is provided on one side of the machine base, a grain tank is provided on the other side, and a straw processing device is provided at the rear of the threshing device. , a special support device for supporting the straw removal processing device by erecting a grain lifting cylinder at the rear of the grain tank and rotatably supporting one side of the straw removal device on the grain lifting cylinder; The above-mentioned problems have been solved by omitting the above problem and by making the straw disposal device rotate smoothly using the cylindrical grain lifting cylinder as a rotational fulcrum.

(E) Function During the harvesting and threshing operation, the waste straw processing device is supported on one side by a strong grain lifting cylinder, and when the sorting chamber of the threshing device is to be maintained and inspected from the rear dust exhaust port, the support member cannot be locked. When the straw removal device is released and pulled toward the grain lifting cylinder, the straw removal processing device smoothly rotates around the outer circumferential surface of the grain lifting cylinder, and the dust exhaust port is opened.

(F) Embodiment 1 is a threshing device that is mounted on one side of a machine base 3 having a traveling device 2 with the dust exhaust port facing backward, and on the other side, in order from the front, an operation panel, a pilot's seat, A grain tank 5 and an engine cover 6 containing an engine are provided, and a pre-processing device consisting of a reaping device and a grain culm conveying device is attached to the front of the threshing device 1 so as to be movable up and down.

Further, a lateral transfer spiral cylinder 7 extending from the bottom of the grain tank 5 projects rearward from the engine cover 6, and a grain lifting cylinder 8 whose upper part is tilted is mounted on the protrusion of the lateral transfer spiral cylinder 7. It has been set up.

A disk-shaped cutter 10 is installed at the rear of the threshing device 1 as a straw processing device, and the cutter 10 has a front-rear surface and a diagonally outward surface on the grain lifting cylinder 8 side. letter-shaped notch 11a
A mounting frame 11 is fixed thereto.

The grain lifting cylinder 8 is made of a cylindrical body with an auger inside, and the grain lifting cylinder 8 has a pair of upper and lower cylinders each having a gutter-like body having a semicircular cross section removably connected with bolts 12, 12. The bodies 13, 13 are rotatably fitted, and the lower edges of the cylindrical bodies 13, 13 are supported by stoppers 16, 16 welded to the grain lifting cylinder 8, and the upper edge of the upper stopper 16 is connected to the grain lifting cylinder. The middle part of the grain lifting cylinder 8 is connected to the side of the rear wall of the threshing device 1 by a stay 18, and is erected integrally with the notch 11a. The pair of upper and lower mounting plates 20, 20 and the dog-shaped mounting plates 21, 21 are welded to the outer peripheral surfaces of the cylinders 13, 13 and are screwed together with bolts 22, so that a large diameter cylinder corresponding to a boss is formed. Heavy snail 10 on body 13, 13
can be firmly installed.

Further, the plate 10c welded to the upper part of the side plate 10a of the cutter 10 connects one end of the pipe 10b to the third side plate 10a.
4 and 6, an L-shaped mounting plate 23 is welded to the lower part of the side plate 10a than the plate 10c, and the side wall 1a of the threshing device 1 is
The upper part of the side wall 1a is cut out so that the plate 10c fits therein, and a U-shaped receiver 25 is welded to the lower part of the side wall 1a corresponding to the mounting plate 23.
The bolt 26 inserted through the hole 3 is screwed into a nut 26a fixed inside the receiver 25 so that it can be attached and detached. Disconnect.

In the above-mentioned combine harvester, the grain culm harvested and transported by the pre-processing device is threshed by the threshing device 1, and the grains are sorted by a swinging sorter installed in the sorting air path, as in the conventional type, and the grains are fried. Grain cylinder 8
The straw waste is fed into the grain tank 5 by the suction windmill or the dust exhaust port and is discharged rearward.

Further, the waste straw discharged from the discharge culm is conveyed and supplied to the cutter 10 by the waste straw conveying chain 27, and the cutter 10 has its blade shaft 28 driven by the V pulley 29 via the X belt 30. Shred the waste straw.

When the swing sorting body is to be maintained and inspected, the bolt 26 is pulled out, the latch 35 is removed, and that side of the cutter 10 is pulled rearward, and the cutter 10 is moved around the grain lifting cylinder 8 in FIG. Since it is rotated from the state shown in FIG. 2 to the position shown in FIG. 2, the dust outlet at the rear of the thresher 1 is opened, and in this state, the swing sorting body or the dust sorting chamber is maintained and inspected.

Furthermore, when the grain tank 5 is full, the machine is brought close to a transport vehicle parked on the road, the upper cylinder of the grain lifting cylinder 8 is erected by the hydraulic cylinder 31, and the motor 32 is started to raise the upper cylinder. By rotating the grain tank 5, the grains in the grain tank 5 are discharged so that its discharge port faces onto the loading platform of the carrier vehicle.

In the above-mentioned embodiment, the straw disposal device was explained as the cutter 10, but the straw disposal device can also be used as a bundling device or a dropper at the rear of the threshing device 1 to perform the same function.

(g) Effects of the invention As mentioned above, the present invention has the threshing device 1 mounted on one side of the machine base 3 with its dust exhaust port facing backward, and the grain tank 5 provided on the other side. Threshing device 1
In a combine harvester in which a straw disposal device is arranged at the rear of the grain tank 5, a grain lifting cylinder 8 is installed upright at the rear of the grain tank 5, and one side of the straw disposal device is rotatably supported by the grain lifting cylinder 8. However, since the other side is removably attached to the support member, the existing grain lifting cylinder 8 can be used to support the straw waste processing device without requiring a special support member or installation space to support it. , the aircraft can be made smaller and lighter, and costs can be reduced.

Further, the heavy straw processing device can be firmly supported and rotated smoothly by using the existing thick grain lifting cylinder 8 as a support shaft.
