Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a side cover of a self-removal type threshing machine for a combine harvester.

(B) Prior Art Conventionally, it is already known to provide a removable side cover for covering a transmission device provided on the outer surface of a feed chin or on the outside of a machine wall.

(c) Problems to be solved by the invention Since the known side cover is screwed on with bolts and wing nuts, it is extremely troublesome to attach and detach it.
And there were times when I lost the butterfly nut.

In addition, the side cover may generate noise due to vibrations of the aircraft body or engine, and the locking device may come off when using the hooking method, but there has been no appropriate and inexpensive preventive measure against these problems.

(d) Means for solving the problem The present invention is a threshing machine in which a side cover is removably attached to the feed chain side, and the receiving part near the bottom of the side cover is connected to and detached from the receiving part protruding from the machine wall. Alternatively, a hook that is rotatably supported and pivotally attached to the upper part of the side cover so as to be tiltable up and down is attached to a stay that protrudes outward from the machine wall, and a plate parallel to the machine wall extends. The above-mentioned problem has been solved by attaching a cushioning material that is locked to the member and pressed into contact with the plate extending from the receiving member near the upper locking portion of the side cover.

(e) Operation When installing the side cover, press down on the grip of the hook, the hook will separate from the receiving member, and can be rotated downward to open or lifted lightly to remove.

Furthermore, when installing the side cover, engage the lower part of the side cover on the receiver or close it and then hang the hook on the support member. Since the hook is in pressure contact with a cushioning material attached to a plate extending from the receiving member, the hook will not come off and will not generate noise due to vibration.

(f) Example An example of the present invention will be explained with reference to the drawings.
A feed chain 2 and a pinch rail 3 are installed opposite to each other on the outside of the handling opening 1 of the threshing machine, and a transmission device 6 for driving the first transfer spiral, the second transfer spiral, and other rotating parts is installed at the bottom of the outside of the machine wall 5. It is provided.

The side cover consists of an upper cover 7 that covers the outer surface of the feed chain 2 and a lower cover 8 that covers the transmission device 6. At the lower part of the inner surface of the upper cover 7, there are a pair of front and rear receiving parts 9 made of bent plates. 9 are welded together, and hooks 11 having gripping portions 10 are provided at the front and rear parts near the top, and the hooks 11,
Brackets 11 are respectively welded to the inner surface of the upper cover 7 and have an L-shape in plan view, and are pivoted so as to be movable up and down in the front and rear direction with fulcrum pins 13, fixed by spring pins 14, and wound. A spring 15 rotatably biases the hook portion so as to lower it, and the grip portion 10 protrudes outward from the notch.

Further, in a portion of the machine wall 5 facing the receiving portions 9, a receiving body 16 is constructed of an L-shaped rod 16a and a pipe 16b made of an elastic material such as rubber or synthetic resin fitted into the rod 16a. and protruding from the hook 1.
1 and 11, a stay 17 is horizontally protruded, and the outer end surface of the stay 17 has a receiving member 18 that is bent toward the machine wall 5 side and engages with the hook 11, and a hanging member 18 that is bent toward the machine wall 5 side. A plate 20 having a portion 19 is screwed to the hanging portion 19, and a mounting portion of a cushioning material 21 made of rubber or synthetic resin is press-fitted into the hole 22 from the outside and fixed thereto. The inner surface of the upper cover 7 is pressed against the outer end surface of the buffer material 21 .

Reference numeral 23 denotes a regulating plate welded to the inner surface of the upper cover 7, which comes into contact with the hanging portion 19 and prevents the upper cover 7 from moving.
prevent it from shifting upward.

The upper cover 7 is constructed so that the lower receiving parts 9 are fitted into and supported by the receiving part, but the receiving part 9 is replaced with a receiving cylinder, and this is loosely fitted into the pipe 16b of the receiving part 16. When the upper cover 7 is rotatably supported, the upper cover 7 may be rotated to open and close around the lower part.

Further, the lower cover 8 has a pair of front and rear round holes 25, 25 in the lower part, and a locking pin 27 is fixed to the inner end of the fulcrum pin 26 inserted into the round holes 25, 25, and the outer end is fixed. A lever 28 is attached to the end, a compression spring 29 is interposed between the lever 28 and the outer surface of the lower cover 8, and spring holders 30 are screwed to the upper part. At the bottom of 5 there are stays 31, 3 whose tips are bent upwards.
1 is fixed, and the locking pin 2 is attached to the bent portion of the
The lower cover 8 When installing, press the spring holders 30, 30 and attach the stays 31,
31, and make the levers 28, 28 horizontal,
It is installed by inserting the locking pins 27, 27 into the long holes 32, 32 and then rotating the levers 28, 28 by 90 degrees.

To remove, follow the steps in reverse.

In addition, if the lower end of the upper cover 7 does not become an obstacle to attaching and detaching the lower cover 8 or rotating the lower part center, the mounting structure of the lower cover 8 may be configured in the same manner as that of the upper cover 7.

In addition, positioning guide rods 35, 35 whose tips are slightly curved downward are provided protrudingly at the front and rear of the lower part of the machine wall 5, as shown in FIGS. 11 and 12, and holes 36, 36 are formed at the front and rear of the lower cover 8. When drilling and installing, the holes 36, 36 of the lower cover 8 are aligned with the positioning guide rod 3.
5, 35 and press it, the heavy lower cover 8 can be easily and accurately positioned.

(g) Effect of the invention The present invention provides a threshing machine in which a side cover is removably attached to the feed chain 2 side as described above, and the receiving part 9 near the bottom of the side cover is connected to the machine wall 5.
A hook 11 is attached to a stay 17 that protrudes outward from the machine wall 5 and is attached to a stay 17 that protrudes outward from the machine wall 5. Plate 20 parallel to wall 5
Since the cushioning material 21 is attached to the receiving member 18 extending from the hook 18, and the cushioning material 21 is attached to the plate 20 extending from the receiving member 18, the vicinity of the upper engagement portion of the side cover is pressed against the hook 11. By operating it, you can attach and detach the side cover with one touch.

Moreover, although the side cover is locked at its upper part by the rotatable hook 11, a plate 20 extending from the receiving member 18 near the lower part of this locking part
Since it is pressed against the cushioning material 21 attached to the
The adjacent portion receives a pressing force in the opposite direction to the tightening direction of the hook 11, which makes it possible to reliably prevent the hook 11 from coming off, as well as press the cushioning material 21 and the plate 20.
Together with the buffering effect caused by the deflection of the side cover, noise caused by the vibration of the side cover can be more reliably prevented.

In addition, since the cushioning material 21 is attached to the plate 20 extending from the receiving member 18, it is possible to easily and accurately manage the dimensions of the mounting positions of the receiving member 18 and the cushioning material 21, and the cushioning material 21 can be attached to the plate 20 extending from the receiving member 18. 20 can be easily assembled.
