Description

[Detailed explanation of the idea] The present invention relates to a body structure in a threshing machine.

In other words, in a threshing machine constructed by installing a foot chain on one side of a handling barrel that is mounted between an inlet side frame plate and an outlet side frame plate, the grain culm conveyed by the foot chain acts during threshing. In order to prevent the frame plate supporting the handling cylinder from being lifted upward or bent in the transport direction, which could cause interference between the extracted teeth and the crimp net side, resulting in deformation accidents or unhandled items, the exit side frame should be To provide a structure in which plates can be firmly assembled and have a simple structure that can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a plan view of a threshing machine mounted on a combine harvester.
A handling cylinder 3 having handling teeth 8 implanted thereon is mounted on a shaft between the inlet side frame plate 1 and the outlet side frame plate 2 on which the supply plate 7 is connected, and the handling cylinder 3 is mounted on one side of the handling cylinder 3 so as to The extending chain stand 9 is connected to both the frame plates 1,
A straw holding plate 10 is provided below the foot chain 4, which is connected and fixed to the end of the foot chain 4 and hung around the chain stand 9, and is constructed in the same manner as the conventional structure.

A downward dust-feeding port 12 is formed between the exit-side frame plate 2 and the partition plate 11 extending below the small-diameter body portion 3a on the terminal end side of the handling cylinder 3, and on the inlet side on the lower side of the handling cylinder 3. A crimp net 13 is stretched between the frame plate 2 and the partition plate 11, and a cutting blade base plate 14 installed facing the other side of the handling cylinder 3 opposite to the foot chain 4 is provided with a crimp net 13. A large number of cutting blades 15 are fixedly installed, and the lower side of a handling chamber side plate 16 installed on the outside of the cutting blade base plate 14 is installed so as to extend to the lower side of the crimp net 13. A swinging sorting body 18 is provided extending from below to below a sorting and dust removal chamber 17 installed in the axial direction of the handling cylinder 3 toward the rear, and is constructed in the same manner as the conventional structure.

A side plate 5 extends from the side of the sorting dust removal chamber 17 to the side of the cutting blade base plate 14 so as to be perpendicular to the outlet side frame plate 2.
is installed, but the end of the cutting blade base plate 14 and the handling chamber side plate 16
The end portion 5a of the side plate 5 is connected to the end side plate portion 11a of the starting plate 11 which is stretched across the end portion of the exit side frame plate 2, and one side of the outlet side frame plate 2 is penetrated through the side plate 5. The flange portion 5bw5c of the side plate 5 at the contact point is fixed to the outlet side frame plate 2.

In addition, the tip 2a of the outlet side frame plate 2 extending slightly outward from the contact point is joined to the central part of the machine frame 6, which is horizontally long in the direction orthogonal to the frame plate 2, and connected and fixed with screws 19. One end side of the machine frame 6 is joined to the outer surface of the case 20a of the suction dust ejector 20 fixedly installed on the outer surface of the side plate 5 and fixed with screws 19, and a machine is attached to the outer surface of the end of the handling room side plate 16. The other end of the frame 6 is joined and fixed with screws 19.

Note that the machine frame 6 is configured to be connected to support a grain lifting cylinder 21.

Therefore, two places, the tip 2a on one side of the outlet side frame plate 2 and the part in the vicinity thereof, are attached to the machine frame 6 and the side plate 5, which are fixed by connecting the suction dust extractor 20 and the handling room side plate 16. It has a structure that is connected and fixed.

For this reason, during threshing, the grain culms conveyed by the foot chain 4 may apply a load as shown by the arrow A in FIG. Even when the load is applied, the outlet side frame plate 2 that supports the handling cylinder 3 maintains its rigidity by supporting at two places, and the handling teeth 8 of the handling cylinder 3 interfere with the crimp net 13 side, causing deformation accidents and unhandled parts. This can be prevented.

As described above, the present invention is a threshing machine in which a foot chain is installed along one side of the handling barrel that is mounted between the inlet side frame plate and the outlet side frame plate, and the foot chain is installed on the side opposite to the foot chain side. One side of the outlet side frame plate is connected and fixed at the contact point of the side plate of the fuselage perpendicular to the outlet side frame plate so as to pass through the side plate, and the outlet side frame plate extending outward from the side plate is connected and fixed. Since the tip is connected and fixed to the machine frame which is fixed by connecting the suction dust extractor and the handling room side plate, the outlet side frame plate that supports the handling cylinder is firmly assembled and supported at two places on the tip side. Therefore, it is possible to create a body structure that can prevent the handling teeth of the handling barrel from interfering with the crimp net side, resulting in deformation accidents and unhandled items.

In particular, in the present invention, since the tip of the outlet side frame plate is connected and fixed to the machine frame which is fixed by connecting the suction dust extractor and the handling room side plate, one side of the outlet side frame plate is attached to the machine body. It has the advantage of being integrated with the side plate of the machine, the suction dust extractor, the machine frame, and the side plate of the handling room, making it even more rigid and robust, and having a simple structure that allows it to be suitably implemented.
