Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a combine harvester for three-row mowing, which has three sets of culm lifting devices installed on the front side of the machine.

"Prior Art" Conventionally, in this type of combine harvester, there is a technology (for example, Japanese Utility Model Application Publication No. 51-42248) in which three short endless belts for scraping the culm are arranged behind three sets of lifting devices. there were.

"Problems to be Solved by the Invention" In the prior art, it was necessary to provide a lateral conveying device above the belt, which made the structure for driving the culms complicated, and it was difficult to simplify the structure. In addition, since there are many forced movement parts of the culm, it is difficult to easily prevent culm breakage and panicle breakage.

``Means for Solving the Problems'' However, the present invention provides a passage forming plate for guiding the culm conveyance in the horizontal direction at the rear of the central part of the culm pulling device for three-row cutting, and a passage forming plate for guiding the culm transport in the horizontal direction. A guide plate for guiding culm lifting is disposed between the lifting devices in the center and approximately parallel to these, and the left and right end portions of the passage forming plate are connected to the central lifting device and each rear surface of the guide plate. The middle of the passage forming plate bent into a shape is extended to the confluence of the left and right upper conveying devices, and the left and right upper conveying covers are placed opposite to the passage forming plate that guides and conveys the tip side of the culm. The left end of the passage forming plate connected to the rear surface of the lifting device is provided protrudingly on the passage side of the two strips, and the rear of the confluence of the two strips at the left end of the passage forming plate extends linearly, and the guide plate The right end of the passage forming plate connected to the rear surface extends linearly rearward and then is bent toward the center of the fuselage.

"Function" Therefore, the tip side of the shell culm taken in by each of the lifting devices can be smoothly moved by the guidance of the passage forming plate and the left and right upper conveyance covers, and the scraping structure on the rear side of the lifting device can be simplified. The drive system can be configured more easily than before, and the raking section can be simplified compared to the conventional three-row cutting structure, and the forced movement of the culm can be reduced, making it easier to break the ears. In particular, by protruding the right end of the passage forming plate connected to the rear surface of the central lifting device to the side of the two passages, the two culms from the two opposing lifting devices can be prevented. The right end of the passage forming plate, which is connected to the rear surface of the guide plate, can be moved and guided in an orderly manner, and the right end of the passage forming plate connected to the rear surface of the guide plate can be moved and guided in a straight line rearward at the right end of the passage forming plate. By extending the shell culm to , the shell culm of the part (■) can be successively inherited from the pulling device, and the culm breakage and desugarization can be reduced compared to the conventional method, and the shell culm can be transferred and guided in a stable manner.

The present invention is constructed as described above, and the plurality of weeding plates 9, 10, 11, 12 provided at the front part divide the erect culm P, and the culm pulling devices 34, 35, 36 raise it. The culm P is pulled up using tines, and the root is cut by the cutting blade 13 of the reaping device 8 (see Figs. 1 and 2), and also by the star wheels 33, 33, etc. of the raking drum 32. The culm P is scraped in, and the root side of the culm P that has been scraped is transferred to the lower conveyance chees 737 and 38, and the tip side is conveyed to the upper conveyance device 41.4.
The culm P between each of the grass dividing plates 9, 10 and 10.11 passes through the first culm passage A as shown by the arrow in Fig. 3 and reaches the confluence C. In addition, the culms P between each of the grass dividing plates 11 and 12 pass through the second culm passage B and reach the confluence C, and after the culms P from each passage A and B merge at this confluence C, The root side of this culm P is inherited by the starting end of the vertical conveyance device 47 and conveyed upward, and from the terminal end is inherited by the starting end of the foot chain 15, and the tip side is inherited by the upper conveying device 41.42. It is supplied to the handling port of the threshing machine 6 at a position away from the threshing machine 6 and is threshed.

Here, the culm P conveyed through each of the culm passages A and B and their merging portion C is connected to the hanging portions 43a and 4.
4. Since it is conveyed while being guided by a, the tip side is sent to the rear side along a plane perpendicular to the field ground.
The grain is smoothly supplied to the supply port of the threshing machine 6.

Moreover, since the above-mentioned upper conveyance cover 43, 44 has its hanging portions 43a*44a arranged vertically,
It is possible to effectively prevent the tip of the culm P from spreading in the left-right direction above the passage and causing the tip to become disordered.
As shown in the figure, the vertical portions 43 of the upper conveyor covers 43, 44
a, 44 Since the spacing between a and 44 a is narrow, corresponding to the passage, the culms can be concentrated well, and as a result, even if broken ears, straw, or broken culms occur, they can be removed on board the aircraft. The grain culm can be smoothly supplied to the supply port of the threshing machine 6 with these miscellaneous substances entangled with the grain culm without causing the grain to fall.
