Description

[Detailed explanation of the idea] The present invention relates to a waste straw conveying device in a threshing machine.

In the conventional waste straw conveying device, as shown in Fig. 1, small pieces of straw waste etc. 4 become entangled in the struts 3 of the waste straw conveying rod 2 which pinches and conveys the waste straw with the waste straw chain 1. This has the drawback that the elastic support of the conveying rod 2 by the spring 5 is hindered, and the straw removal process cannot be carried out smoothly.

In addition, there is a large space between the straw removal conveying rod 2 and the machine body below, and there is a drawback that dust discharged from the threshing section after passing over the No. 4 receiving plate is likely to be scattered outside through the space. In addition, weeds, weeds, and mud attached to the stock side of the transported waste straw are separated during transportation, and flow into the No. 4 receiving plate side through the space, and are deposited on the No. 4 receiving plate side. There were disadvantages such as the mud getting stuck in the chain and getting clogged or getting wrapped around the chain, and the mud getting mixed in with the recovered grain.

By providing upper and lower plates, this invention can effectively cope with fluctuations in the amount of transported and discharged straw, while also effectively preventing straw waste from wrapping around the support, and preventing dust from scattering from the threshing section to the outside. , the purpose is to also prevent foreign matter from flowing into the No. 4 receiving plate side from the outside.

Next, an embodiment of the present invention will be explained based on FIGS. 2 and 3.

Reference numeral 6 denotes a waste straw conveying device for transporting the waste straw that has been threshed by the threshing section of the combine, 8 a waste straw chain driven by an appropriate transmission mechanism, and 9 a waste straw conveyor for holding and transporting the waste straw between the waste straw chain and the waste straw chain. It is a straw transport rod.

10 and 10' project downward from the lower ends of the transport start end and transport end sides of the waste straw transport rod 9, respectively, and slide into holes 14 and 15 provided in the fuselage 11 and spring seats 12 and 13 of the combine, respectively. Posts inserted freely, also 16.17
are the springs installed between the body 11 and the spring seats 12 and 13, respectively, and the supports 10 and 10' and the springs 16 and 17
The waste straw conveying rod 9 is elastically supported by the machine body 11, and the conveying rod 9 is moved up and down according to fluctuations in the amount of conveyed and discharged straw.

Next, reference numeral 18 denotes an upper plate projecting downward from the lower end of the transporting rod 9, which connects the lower end of the transporting rod 9 and the support column 10;
It is fixed to the side of the conveyor rod 9 and the support column 1.
0 and 10' move up and down integrally with each other; 19 is placed close to the plate 18 with a slight gap 1;
From the machine body 11 located below the conveying rod 9, the space between the pair of support columns 10° and 10' is a plate body extending almost the entire length, and these drawing plate bodies 18 and 19, in plan view, It is positioned between the pair of left and right link plates of the straw removal chain 8, and at least in the straw removal conveying device, the lower end side of the upper plate 18 and the upper end surface of the lower plate 19 are lapped in a side view, and the straw removal is transferred. A rod 9, a fuselage 11 located below the transport rod 9, and a pair of struts 10;
The space surrounded by 10' is closed by drawing board bodies 18 and 19 to prevent straw waste from flowing in from the A side to the B side shown in FIG. 3 and from the opposite direction, and from scattering dust. It is composed.

As explained above, in the straw removal conveying device of the present invention, almost the entire space surrounded by the removal straw transfer rod, the machine body located below it, and a pair of supports is covered by a Since it is closed by the side plate and the lower plate that stands up from the machine body, even if straw waste tries to wrap around it, it will be blocked by one of the drawing board bodies, effectively preventing it from wrapping and preventing transport caused by wrapping. Defects in elastic support for the rod can be reliably avoided and waste straw can be conveyed smoothly.

In addition, the drawing board body is arranged close to each other so as to be located between the pair of left and right link plates in a plan view, and the lower end side of the upper plate body and the upper end side of the lower side plate are wrapped, at least in the state of removing straw being conveyed, in a side view. Therefore, while maintaining the closed state with respect to the space, the upper plate body, that is, the conveying rod, can be moved up and down over a large range, regardless of the displacement of the upper plate body due to fluctuations in the amount of conveyed and discharged straw. When the waste straw is being transported, the flow between the threshing section and the outside can be reliably blocked by the drawing board, and it is possible to effectively prevent dust from scattering from the threshing section to the outside, and to prevent dust from getting tangled on the stock side of the transported waste straw. It is now possible to reliably prevent weeds, attached mud, etc. from separating during transportation and the separated foreign matter from flowing into the threshing section.
