Description

[Detailed description of the invention] The present invention is equipped with a straw disposal section behind the threshing section, a straw disposal cutter is provided in the processing section, and a straw disposal chain for transferring the straw to the cutter is installed above the cutter. The present invention relates to a waste straw processing device.

Conventionally, there was a technology that provided two upper and lower straw removal conveyors and moved the upper one at high speed. As each conveyor was set up in tension and each conveyor was driven by two different drive system paths, the feed chain and each conveyor were inherited from each other, and each conveyor when straw was not processed. It is difficult to properly discharge the waste straw, and in particular, it is difficult to align and focus the waste straw, and it is also difficult to simultaneously drive and stop the upper and lower transport bodies, and the drive structure of each transport body is difficult to achieve. There was a concern that this would complicate the process and increase the number of damaged areas in the event of an emergency such as a straw jam.

The present invention solves the above-mentioned conventional drawbacks, and has a structure in which two upper and lower straw transporting bodies are installed in series at the end of the feed chain, and the feeding speed of the upper conveying body is faster than that of the lower conveying body. , the feed start ends of the transport bodies positioned above and below face the end of the feed chain at approximately the same position and from the same direction, while the feed ends of each of the transport bodies are located at approximately the same length, and are lined up with the upper transport body. The culm guide to be installed is attached to a certain length, and the wandering straw guide installed in parallel on the lower conveyor is shorter than the culm guide when the straw is being cut, and is approximately the same as the culm guide when the straw is not being processed. This system uses a small-diameter sprocket on the lower conveyor that is linked to the feed chain, and connects the upper conveyor to the feed chain. The straw can be stretched compactly in a vertical position, and the straw that has been moved to a vertical position can be selectively dropped below either the middle or the end of the lower carrier, and the straw can be inherited by the upper and lower carriers, and the straw can be taken over by the upper and lower carriers. The straw can be smoothly conveyed to the desired position with proper discharge and alignment, for example the cutter or focusing arm can be easily placed in the most functional position by coordinating it with the overall structure of the combine. At the same time, each upper and lower conveyor can be linked to the feed chain with a simple drive structure,
It is an object of the present invention to provide a straw disposal device for a combine harvester that is capable of minimizing damage and interrupting work in the event of an accident such as straw clogging by controlling the simultaneous operation of the feed chain and each conveyor. An embodiment of the present invention will be described in detail based on the drawings.

The present invention is constructed as described above, and in conjunction with the feed chain 15, a straw removal chain 16 and a straw removal belt 17 are provided.
is driven, and the waste straw is transferred to the end by the feed chain 15 with the tip part inserted into the fourth gutter 55, and the waste straw is transferred to the waste straw chain 16 extending approximately at right angles to the feed chain 15. When the straw removal is carried over and the upper surface of the straw removal cutter 18 is closed with the shutter 80, the straw removal guide 46
expands, and the high-speed straw removal belt 17 transports the straw to the culm.
The waste straw sent with the culm at the top is dropped and accumulated on a convergence arm 20 attached to a bracket 19.

On the other hand, the shutter 80 is removed from the upper surface of the straw removal cutter 18, the cutter guide 73 is oscillatedly moved from the rear surface of the frame plate 62 to this upper surface, and the straw removal cutter 18 is driven via the manual coupler 86. and said chain 16
The waste straw sent by the threshing section 4 passes between the rear surface of the threshing section 4 and the cutter guide 73, and at this time, the waste straw is bent into a V shape by the finger claws 71 and sent to the raking rolls 60, 61. The waste straw is supplied to the cutting blade 58 and the receiving blade 59 through the cutting blade 58 and the receiving blade 59, and the waste straw is cut to an appropriate length and scattered on the field from the discharge port 74.The cutting process of the four waste straw and the convergence process are performed. can be selected as necessary.

As shown in the embodiments above, the present invention has a feed chain 15
In this structure, two upper and lower straw evacuation conveyors such as a straw evacuation chain 16 and a straw evacuation belt 17 are connected at the end, and the upper and lower conveyance bodies 17 are fed at a higher speed than the lower conveyance bodies 16. Each of the carriers 16 to be positioned. 17 facing the end of the feed chain 15 at substantially the same position and from the same direction, while each of the conveyance bodies 16. 17 are located at approximately the same length, and the culm guides 53 installed in parallel to the upper carrier 17 are attached to a constant length, and the lower carrier 1
Straw removal guides 45 and 46 are arranged in parallel with each other in the feed chain. The small-diameter sprocket 40 of the lower conveying body 16 that is linked to the feed chain 15 is used to interlock and connect the upper conveying body 17 to the feed chain 15. Compared to the conventional method, the upper and lower conveying bodies 16 and 17 can be stacked in a stacked state.
