Description

[Detailed Description of the Invention] The present invention relates to a grain culm supply guide device to a threshing section in a combine harvester.

That is, a combine configured by extending a culm guide rod from near the end of a vertical conveyance chain that supplies the culm side of the grain culm from the reaping side to the feed chain of the threshing section to the lower side of the starting end of the feed chain. In this case, the culm guide rod, which supports and guides the culm side of the grain culm, is deformed due to clogging during bundle handling work during manual handling or during normal harvesting and transportation. To provide a structure that can reliably and well guide the culm side of a grain culm by simply changing its posture without deformation, can support and guide well without causing any trouble, and has a simple structure so that it can be carried out suitably. It is something.

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

FIG. 1 shows a side view of the combine harvester, and on a machine stand 6 supported by a crawler 5, the feed chain 1 and the trapping rods are arranged so that the starting end of the feed chain 1 extends forward from the starting end of the trapping rod 7. In front of the threshing section A, there is a reaping section B equipped with each weeding board 8, each raising case 9, a cutting blade 10, a conveyor, etc., which is equipped with a hydraulic cylinder 11. It is installed in such a way that it can be adjusted up and down, and has the same structure as the conventional structure.

From the rear of the reaping section B to the front of the threshing section A, a vertical conveyance chain 2 is installed obliquely so that the terminal end 2a approaches the lower side of the starting end of the feed chain 1. The upper part of a long support case 12 that transmits power to the chain 2 and serves as a support part is integrally connected, and the rotating case 12a installed at the lower part of the support case 12 is placed in front of the threshing part A. A gripping body 14 is rotatably connected to the fixed transmission case 13 and extends along the conveying surface side of the vertical conveying chain 2, and is installed so as to be supported by a support frame 15 with pressure. The U-shaped rod 16 extending from the side of the vertical conveyance chain 2 is installed so that the support frame 15 can be supported, and by rotating the rotating case 12a, the inclination of the vertical conveyance chain 2 can be changed and the handling depth can be adjusted. It is installed in the same manner as the conventional structure.

3 is a culm guide rod, which is located at the end 2 of the vertical conveyance chain 2.
It extends close to the terminal end 2a so as to be able to support and guide from below the culm side end of the grain culm which is transferred and supplied from the side a to the starting end side of the feed chain 1 and the trapping rod 7. The culm is arranged so that the end 3b of the culm guide rod 3 is located near the upper side of the rotating case 12a, and the rod body is bent so that the free end side of the one end 3a is located in front of the starting end of the culm rod 7. Former guide rod 3
is made into a rigid body and bent to form the end 3 of the culm guide rod 3.
A connecting plate 17 is fixedly attached to b by welding, a supporting plate 19 is fixedly attached to the upper side of the rotating case 12a by each bolt 18, and a rubber plate of a constant thickness is installed between the connecting plate 17 and the supporting plate 19. A cushioning body 4 made of aluminum is interposed therebetween, and the two are connected by bolts and nuts 20.

Therefore, during combine harvesting operation, the culm side of the grain culm is lifted up and conveyed by the vertical conveyance chain 2, and at the terminal end 2a side, the culm tip side is supported and guided by the culm guide rod 3 while being transferred to the feed chain 1 as it is.
It will be passed on and supplied between the
Even if the vertical conveyance chain 2 changes its inclination to adjust the handling depth, the culm guide rod 3 rotates together with the rotation case 12a, and the supporting and guiding posture remains unchanged.

In addition, when manually feeding grain culms to the threshing section A, the terminal end 2a of the feed chain 1 and the vertical conveyance chain 2 is
The rice bundle will be supplied from between the culm and the culm side tip will be supported and guided by the culm guide rod 3 in the same manner as described above.

In this way, even during normal combine harvester work or manual handling work, the culm guide rod 3 that supports and guides the culm tip side is itself a rigid body, so it can guide without deforming. At the same time, the culm side can be supported with pressure while changing its posture due to the cushioning provided by the buffer body 4 on the support side.

In this way, the present invention extends the culm guide rod from near the end of the vertical conveyance chain that supplies the culm side of the grain culm from the reaping side to the feed chain of the threshing section to the lower side of the starting end of the feed chain. In the combine, the culm guide rod is bent into a rigid body, and one end on the feed chain side is a free end, and the other end of the culm guide rod is provided with a buffer body on the support side of the vertical conveyance chain. Since the culm guide rods are interposed and connected in a row, there is no longer a problem where the culm guide rods themselves become deformed due to clogging during bundle handling during manual handling or clogging during normal harvesting transportation. , the culm side of the grain culm can be reliably and well guided by simply changing the posture with the buffer provided by the buffer without deformation, and it is suitable for its simple structure as it can support and guide well without causing any trouble. It has the advantage of being able to be implemented in many ways.
