Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a combine harvester that reaps and threshes grain culms and bundles and discharges waste straw.

(B) Prior Art Conventionally, when the waste culms discharged from the threshing device of a combine harvester are tied with a binding device attached to the rear of the machine and discharged to the harvested field at the rear of the machine, the tip side is held by a resistance rod. After the straw bundle is stopped and the straw bundle is turned, it is released and the culm that is supplied to the bundling device is guided by a raking wheel and a guide rod that is not related to the culm.

(c) Problems to be solved by the invention If only the resistance rod is used, the straw bundles are difficult to separate, resulting in the discharging posture being disturbed; As a result, the bundled culms became intertwined with the following shell culms, which disrupted the posture of the bundled culms and caused poor bundle separation.

If a raking wheel is installed at the bottom of the feed route on the stock side in order to solve this problem, the raking wheel will scrape up the culms, which will not only significantly disturb the stock side that should be bundled, but also cause damage to the packer. In order to improve this problem, when the raking wheel is placed so as to face the feeding path from above, the culm's stock base protrudes laterally, but the panicle is not smooth. Since the side is usually adjusted to eject at a substantially constant position, the transmission shaft of the raking wheel must be taken from the ear side. With this configuration, the culm is wound around the transmission shaft. At the same time, the transmission shaft becomes a hindrance, making it difficult to guide the grain toward the ear.

(b) Means for solving the problem The present invention provides a combine harvester that can supply the culms to the tying device in an orderly and well-aligned manner, and that can discharge the straw bundles without getting entangled and with good separation. The object is to provide a binding device, in which a combine harvester is equipped with a binding device 5 on the culm discharge side of the threshing device 1, and a guide plate 1 is provided at the lower part of the culm receiving side of the binding device 5.
1, and a raking wheel 12 is provided on the upper part of the guide plate 11 on the side of the stock, and a raking ring 12 is provided to transfer the culm's stock part to the packer 8 of the bundling device 5, and the raking ring 12 extends from the panicle side. A binding device 5 is attached to the upper part of the guide plate 11 on the ear side.
An elastic guide is provided which is attached to the fixed member, and the elastic guide extends forward from the base, and when viewed from the culm direction, the lower part wraps from above the rotational trajectory of the scraping wheel 12 through the front of the upper part. After detouring in an arc shape, guide plate 1
1, the rear end extends toward the guide plate 11.

(E) Operation When the waste culm discharged from the threshing device is supplied to the binding device, the soft and easily disturbed ear side of the waste culm is placed at the front of the rotation trajectory of the raking wheel before being raked by the raking wheel. The holders are stopped by the elastic guide rods above and aligned, and then raked by the raking ring, and the packer of the bundling device rakes the above-mentioned culms into the collecting culm, and when a predetermined amount is reached, they are tied at the knot. The discharge arm discharges the material diagonally to the mowed field behind.

(F) Embodiment An embodiment of the present invention will be described with reference to the drawings. 1 is a threshing device mounted on the base of a combine harvester, and a foot chain 2 and a clamping rail are installed along the handling opening of the threshing device. A straw removal chain 3 and a straw removal belt 4 are stretched from the end of the foot chain 2 toward the rear center of the machine body, and the straw removal chain 3
The terminal end thereof protrudes rearward from the straw removal belt 4.

Reference numeral 5 denotes a binding device installed at the rear of the threshing device 1 so that the ear side receiving side is in front of the stock head side receiving side. A downwardly inclined guide plate 11 is provided over the culm collecting portion 10 formed between the nodule portion 9 and the culm collecting portion 10 .

A pair of left and right raking wheels 12.1 forming a transport body are disposed on both sides between the terminal end of the straw removal cheno 3 and the packer 8.
2 is attached to a shaft 13 that is forcibly driven, and on the side of the ear, a guide plate 11
, the culm is inclined to a part corresponding to the scraping locus of the packer = 8, and the culm is weakly clamped and guided at first, and the culm collection part 10
An elastic guide body 14 is provided, which is made of a band-shaped elastic plate and is designed to be resiliently supported sequentially as it approaches.

In addition, clamping rails 15 and 15 are provided opposite to each other on the lower surfaces of the straw removal cheeper 3 and the straw removal belt 4.

In the above-mentioned device, the husks that are threshed by the threshing device 1 and discharged from the culm opening 1a are transferred to the straw removal chain 3 and the straw removal belt 4 at the end of the foot chain 2, and are directed toward the center of the rear of the machine. It is then sent diagonally backwards.

The culms that have fallen from the end of the transfer are placed on the guide plate 1.
1, the spike side is caught by the curved portion of the elastic guide body 14 and protrudes forward from the rotation locus of the raking wheel 12, and is held together and weakly supported and braked while the guide plate 11''2 While the stock is moved little by little, the stock part is moved by
, 12, the culm ends up turning around the tip of the stalk in a fan-shaped trajectory.
When the tip reaches the strong pressure part of the elastic guide 14, the packer 8 sequentially converges on the collecting culm along a trajectory that partially overlaps the raking locus of the raking wheels 12, 12 when viewed from the culm direction of the culm.

Next, when a certain amount of the culms are collected, the door 16, needle 7, and knot 9 are activated to bundle the culms, and the discharge arm 17 discharges them to the mowed field behind.

(G) Effects of the invention The present invention provides a combine harvester in which a binding device 5 is installed on the culm release side of the threshing device 1 as described above.
A guide plate 11 is provided at the lower part of the culm receiving side, and the guide plate 11
A raking wheel 12 for transferring the culm's stock end to the packer 8 of the bundling device 5 is provided on the upper part of the stock side of the culm, and the raking wheel 12 is attached to a shaft 13 extending from the panicle side. An elastic guide whose base is attached to the fixing member of the bundling device 5 is provided on the upper part of the panicle side of the guide plate 11, and the elastic guide extends forward from the base, and when viewed from the culm direction, the elastic guide Since the wheel 12 is detoured in an arc shape from above the rotation locus of the wheel 12 through the upper front and the lower part wraps, the rear end is extended along the guide plate 11 so that the rear end approaches the guide plate 11. The culms discharged from the threshing device towards the binding device temporarily become unregulated and their posture tends to be disturbed, but the tips of the culms are shaped like an arc that protrudes forward from the rotation locus of the raking wheel of the elastic guide. The new curve section stops the holders and guides them together, and in this state the raking wheel cooperates with the guide plate to rake the culm in an orderly manner towards the packer, preventing the culm from being disturbed or entangled. In addition, even though the raking ring extends from the panicle side, the stock side is held down by the raking ring, and the panicle side is protected by the elastic guide that detours from the top to the front, and the above-mentioned shaft is protected. The culm does not wrap around the culm, and as a result, the culm can be collected and bundled in an orderly manner, and there is no connection between the bundles, allowing smooth unrelease.
