Description

Detailed Description of the Invention "Industrial Field of Application" The present invention is directed to the use of a combine harvester for multi-row cutting. Connect the lower part and the - side part to the lower conveyor chain and -1
This relates to a device that transports the aircraft to the rear side while being supported by a transport device.

"Prior art" Previously, Utility Model Publication No. 49-10778 and Utility Model Application Publication No. 1977-1
As shown in each publication of No. 08333, the husks guided to the lower conveying chain are sent in the horizontal direction, merged with the body on the front side of the threshing machine, and then the merged culms are conveyed vertically. There was a technology to transport the material to the starting end of the foot chain using a device.

[Problems to be Solved by the Invention] In the prior art, the overall structure of the shell culm conveying device that sends the cut husks to the threshing machine is relatively complicated, and the manufacturing cost thereof is high. In particular, attaching a cross-feeding device such as a lower conveying chain to join grain culms from each culm passageway inevitably complicates the structure and increases manufacturing costs as described above.

Therefore, Utility Model No. 50-35734 and Utility Model Publication No. 1973-
As shown in each publication of No. 4577, the front side of the fuselage is wide 11
A letter-shaped shell culm passage is formed on the surface, and the letter-shaped shell culm passages are merged on the rear side, and the starting end of the conveying body capable of adjusting the length and shortness of the culm is faced behind the merging part. There was technology.

In the conventional technology in which the culm passage is formed in a curved shape like this, there is no need to cross-feed the reaped culm to the side of the machine and merge it, and the reaped culm is moved to the rear of the center of the cutting blade in the shortest distance. Therefore, it was possible to easily simplify the structure of the cutter culm, such as the lower conveying chain, and reduce costs. However, the starting end of the conveyor was placed facing the confluence of the left and right lower conveyor chains that formed the V-shaped shell culm passage, and the left and right cut culms were simultaneously transferred to the conveyor. Problems such as disturbed transportation posture of the cut husk culm at the core and culm clogging are likely to occur.In particular, when adjusting the length and shortness of the culm, the conveying body approaches and separates from the merging section of the lower conveying chain, causing the husks at the juncture to become unsteady. Culm inheritance becomes extremely unstable,
There were problems such as the culm easily falling off.

Therefore, in the above-mentioned Japanese Utility Model Publication No. 49-1077Et, etc., the starting end of the conveying body is provided approximately parallel to the terminal end of the do part conveying chain. There is also a technique to ensure that the reaped culm is passed on to the reaped husk, but in this conventional technology, since the conveying surface of the F section conveying chain and the conveyor body was in the same direction with respect to the reaped husk culm, each culm guide was also inherited from the reaped husk. The shell culm is pressed against the shell culm from the same direction, and the moving speed of the shell culm that is forcibly moved by the conveying chain and conveyor and the shell culm that is pressed against the culm guide tends to be different, and during the conveyance. In addition, there is a problem that the culm is twisted, causing culm breakage and de-earing, and the structure of the conveyor in the conventional technology requires two wooden conveyor chains to be installed between the conveyor and the foot chain. .

Furthermore, as a means to solve the above-mentioned conventional problems, as shown in the publications of Utility Model Application No. 50-96541 and Utility Model Application No. 50-97939, the end of the right lower conveyor chain is extended to the start end of the foot chain. There was a technique to merge the shell culms from the lower conveyance chain on the left in the middle of the chain. According to this conventional technology, the reaped husk culm could be moved extremely smoothly by the left and right lower conveyor chains, but the conveyer was placed behind the confluence of the left and right husk culms in the middle of the lower conveyor chain that extends to the foot chain. Since the culm of the conveyor body is adjusted in length and short, the shell culm that is in contact with the lower conveyor chain in a non-pinch state is likely to be bent or cut due to the contact, and the lower conveyor chain that extends to the foot chain is likely to be bent or cut. Since the length of the chain is extremely long, it is difficult to assemble and disassemble the chain, and the driving force and noise of the chain cannot be easily reduced.

"Means for Solving the Problems" However, the present invention forms a letter-shaped shell culm passage in a wide plane on the front side of the fuselage, and merges the letter-shaped shell culm passages on the rear side. , in a combine in which the starting end of a conveying body whose length can be adjusted is faced behind the merging part, the terminal end of the lower conveying chain forming the one culm passage is bent near the merging part of each passage. , the terminal end of the lower conveying chain is disposed substantially parallel to the conveying body, while the terminal end of the lower conveying chain and the conveying surface of the conveying body are disposed to face each other, so that the left and right lower conveying chains have a V-shape. After all the shell culms are merged at the intersection, the shell culms are transferred to the conveying body from the terminal bent part of the lower conveying chain.

"Function" Therefore, the culm passage can be manufactured at a low cost with a simple structure, and the conveyor can be moved by adjusting the length of the culm.
The culm can be properly inherited from the lower conveyor chain even if the culm is transferred properly, and culm inheritance malfunctions and conveyance disturbances can be prevented without the need for a complicated culm guide. In particular, compared to the conventional technology in which the starting end of the conveyor faced the confluence of the shell culms of the left and right lower conveyor chains, it is possible to easily obtain a stable flow of +9 by taking over the shell culms after merging.
It is possible to prevent disturbances in the conveying posture of the shell culm and clogging of the shell culm at the starting end of the conveyor body, and to prevent the shell culm from falling off at the merging and joining parts of the left and right shell culms.
1111= It is possible to easily improve the safety of the conveying work, and compared to the conventional technology in which the starting end of the conveying body is provided parallel to the end of the lower conveying chamber and these conveying surfaces are formed in the same direction, the merging of the shell culms is By arranging the conveying surfaces of the lower conveying chain and the conveying body to face each other at the transfer section and the transfer section, culm breakage and ear removal due to twisting of the culm can be prevented, and the merging and transfer of the husk can be carried out smoothly and stably. In addition, the lower conveyor chain and the conveyor body can be placed between the cutting blade and the foot chain in the shortest possible range, and the conveyor chain is interposed between the conveyor body and the foot chain as in the past. The support structure on the starting end side of the lower conveyance chino and the support structure on the conveyor body support structure on the end side of the lower conveyance chino are simpler than before, and their assembly and disassembly can be simplified, and handling operations are easier than before. It is possible to easily and stably and safely feed the harvested grain culm to the starting end of the foot chain.
