Description

[Detailed Description of the Invention] This invention relates to a pinning rod support device in the threshing section of a combine harvester.

Conventionally, the straw conveying device in the threshing section of a combine has been provided with a feed chain for conveying the straw along the handling drum, and a feed chain was installed along the feed chain, and the straw conveyor was installed in parallel with the feed chain. The feed chain is supported by a support rod and attached to the machine body, but when the feed chain becomes clogged with straw, removing it is complicated and causes a decrease in work efficiency.

In this invention, the lower end of a shaft whose upper part is bendable is screwed upright onto a receiving plate protruding from the fuselage, and the coaxial body is fitted into a cylindrical body fixed at a predetermined location on the outer surface of the support rod. A pinning rod support in a threshing section of a combine harvester, characterized in that the upper part of the shaft is bent and the lower end threaded part is pressed downward to fix the support rod to a receiving plate protruding from the machine body. The aim is to provide the equipment.

An embodiment of this invention will be explained in detail based on the drawings. A is a combine harvester, which is composed of a reaping section a and a threshing section b.

The reaping section a is located at the front of the machine and consists of a grain culm pulling device, a cutting blade, etc. A threshing section b is mounted at the rear of the machine. feed van,
Karakin, Chafrape, Glensieve, No. 1 conveyor, 2
Structures such as a number conveyor and a straw rack (none of which are shown) are provided.

A straw conveying device 2 is provided at the center of the machine on the side of the reaping section a, and the straw conveying device 2 is connected to a feed chain 3 that conveys the straw while inserting the tip into the handling cylinder 1. Anchor rods 4 installed above the eid chain 3 and the same rods 4
A support rod 5 supports the feed chain 3 from above, and a support rod 4 is supported by the support rod 5 and is located below the support rod 5, and the straw is threshed between the support rod 4 and the feed chain 3. The waste straw is then transported to the waste straw processing section C located at the rear of the machine.

The support rod 5 is fixed to the fuselage, and the clamping rod 4 is located above the feed chain 3 via the support rod 5. A receiving plate 6, a shaft body 7 whose lower end is screwed to the receiving plate 6 and whose upper part is bendable, and a cylindrical body 8 fixed at a predetermined location on the outer surface of the support rod.
Therefore, when fixing the support rod 5 to the aircraft body, the shaft body 7 is first set up in a straight line, the cylinder body 8 is fitted into the shaft body 7, and the cylinder body 8 is placed on the receiving plate 6. Then, bend the upper part of the shaft 7 so that the bent part 9 is straight with the shaft 7, and rotate the bent part 9 to form the threaded part 10 at the lower end of the shaft 7.
The shaft body 7 is rotated in the downward tightening direction by
is in contact with the upper edge of the cylinder 8 on the side of the support rod 5, and the cylinder 8 is supported and fixed by the bending part 9 and the receiver 6 to fix the support rod 5. When removing, rotate the shaft body 7 using the bending part 9, loosen the lower end screwing part 10, raise the shaft body 7, and remove the notch 1 provided in the circumferential wall of the cylinder body 8.
1 to put the bent part 9 in a vertical state (see Fig. 5),
This is done by pulling out the cylindrical body 8 from the shaft body 7.

In this invention, because of the above structure, the cylindrical body of the support rod can be attached and detached by bending and extending the shaft body, making it easy to remove straw if it becomes clogged in the straw conveyor. In addition, when servicing or cleaning the straw conveying device, the support rods and the pinning rods can be removed, which has the effect of making maintenance and cleaning operations easier.
