Description

[Detailed explanation of the invention] (a) Industrial application field This invention is a straw harvester that transfers the waste straw culm after threshing from the threshing machine to the waste straw processing equipment in combine harvesters, self-propelled self-shedders, etc. Regarding a conveyance device.

(b) Conventional technology In combine harvesters and self-propelled self-shedding, one or more types of waste straw processing devices such as cutters, concentrators, and binding devices are installed near the straw opening of the threshing machine. The waste straw culms discharged from the threshing machines are processed by these waste straw processing devices and then released into fields, etc., but the waste straw culms are not sent to the waste straw processing devices. If the feeding is not done in an orderly manner, problems such as variations in the cut length by the cutter, bundling errors, and poor bundle alignment may occur.

By the way, when the stem culm is subjected to handling action in the threshing machine section, the handling action causes the tip side of the culm to be delayed in transfer, and moreover, the tip side of the culm is lowered, causing the entire culm to convex downward. Since it is in a bent posture, the straw culm sent out from the threshing machine as a straw culm in that state is corrected before being sent to the straw processing device, and is fed into the waste straw processing device in an optimal posture. It is necessary to perform a gesture that makes the movement similar to that of the previous example.
Publication No. 150770, Publication No. 53-119358, Publication No. 119358, Publication No. 119358, Publication No. 119358, Publication No. 119358
Measures such as those seen in Publication No. 53-29952 are adopted.

(c) Problems to be solved by the invention Among the conventional structures, the one seen in Japanese Utility Model Application No. 53-150770 has a structure in which a plurality of grain culm discharge devices connected to a feed chain are arranged in parallel in the grain culm direction. It consists of a number of wrapping belts, and the speed difference between the multiple belts is used to correct the transfer delay on the grain tip side. The problem is that it becomes complicated and large.

Furthermore, in the conveyor device disclosed in Japanese Utility Model Application Publication No. 53-119358, in which the waste straw culm is fed into the waste straw processing device while being held in the feed chain, the tip side of the waste straw culm is supported by a support rod. At the same time, the straw stock side is constructed so that it is in an upward position just before it falls into the waste straw processing equipment, but although this eliminates the complexity of the equipment, it However, the posture in the transport direction is only positively corrected, and the posture in the transfer direction is not corrected with less sliding resistance, which is insufficient.

Furthermore, in the conventional method disclosed in Japanese Utility Model Application Publication No. 53-29952, a waste straw conveying chain is installed in series at the end of the feed chain, and the ends of the inner and outer walls of the pinching rails opposite to the feed chain are installed at the joint between the two. Of these, the inner one is configured to be able to expand and contract to suitably lengthen the straw culm in order to improve the transfer of the straw culm. Although it is possible to correct the posture of the straw culm, the degree of correction is small, so it is possible to tilt the straw conveying chain toward the inside of the machine body in plan view with respect to the feed chain so that the straw culm is not discharged with the tip of the straw behind. Even when the straw is sent to a processing device, it is constructed so that it enters the device in a parallel position, and because the straw conveying chain is tilted, the drive system is complicated.

In this way, all of the conventional structures have advantages and disadvantages, and while the whole device is simple, it is possible to sufficiently correct the posture of the waste straw culms both in the transport direction and in the vertical direction before sending them to the waste straw processing equipment. Since it is insufficient in terms of the ability to contain waste straw, the present invention aims to provide a waste straw conveying device that can satisfy this point.

(d) Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a method in which the straw that is transferred and discharged by the feed chain mechanism of the threshing machine is installed near the straw opening of the threshing machine. In a combine harvester configured to feed waste straw to a processing device for processing, the terminal end of the strapping rail opposite to the lower side of the feed chain mechanism is configured such that the terminal end of the inner wall thereof is appropriately longer than the terminal end of the outer wall. At the same time, the straw conveying mechanism, whose starting end is connected to the terminal end of the feed chain mechanism, is installed parallel to and outside the feed chain, and is installed so that the starting end is connected to the terminal end of the feed chain mechanism, and is installed so that the starting end is connected to the terminal end of the feed chain mechanism. A base of an elastic guide member is attached to the front part of the straw to support the straw culm from below and correct and guide the tip of the ear to a horizontal position. The structure extends toward the inner rear so that the degree of separation from the straw increases. The structure is such that it is supported from below, lifted and corrected, and placed on the terminal end of the pinning rail.

(E) Effect According to the present invention, when the feed chain mechanism firmly clamps the base of the stock of waste straw sent out from the threshing section, the elastic guide member extending inwardly and backwardly is conveying the waste straw. The culm is brought into contact with the removed straw, starting from the part near the base of the plant and moving towards the tip of the plant, changing the contact points. The share is held at two locations in the inner and outer wall of the outer and external wall due to the structure of the inner wall, which is led to the end of the inside wall, which is longer than the end of the outer wall, as the exhausted rail ends. Of the clamps, the clamps on the side closer to the stock end are released, and only the part near the tip of the stock is clamped so that the posture of the straw can be easily changed both in the front and back direction and in the vertical direction. Feed that compensates for the transfer delay on the ear side can be applied to correct the posture in the front-back direction and then feed the waste straw to the waste straw processing device. The posture can be changed smoothly up and down and back and forth without applying excessive resistance, and the straw can be supplied to the waste treatment equipment in an extended state with no bends and in a well-aligned state both front and back and up and down. However, regardless of whether such waste straw can be supplied, the waste straw conveying mechanism is simply installed parallel to the feed chain, the lengths of the inner and outer walls at the ends of the pinning rails are made different, and elastic guide materials are installed. This structure has a simpler structure compared to conventional systems in which the waste straw conveyance mechanism had to be tilted with respect to the feed chain, or in which multiple waste straw conveyor belts had to be arranged in parallel in the culm direction and had different speeds. It becomes much more concise.

(F) Embodiments Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

The illustrated embodiment shows an example in which the present invention is incorporated into a combine harvester having two systems of waste straw processing equipment.

In the combine C, a reaping conveyance section 3 is attached to the front part of a machine base 2 supported by a crawler type traveling device 1 so as to be able to rise and fall freely, and a starting end of a threshing feed chain mechanism 5 is attached to the terminal end of a stock conveyance chain 4 of the section 3. It is formed by mounting a serial threshing machine 6 and an engine 9 on its side for operating a grain collecting section 7, a control section 8, and the aforementioned mechanisms 1, 3, 6, etc.

The threshing machine 6 houses a handling barrel with the handling barrel axis facing the direction of movement of the machine, and the front part of this handling compartment facing the reaping and conveying section 3 serves as a supply port, and the rear part serves as a supply port. A straw discharge port 10 is formed in the straw discharge port 10, a handling port is opened in the side wall of the machine between the supply port and the discharge port, and a feed chain mechanism 5 is rotatably wound and hung on the outside of the handling port. There is.

The winding installation of the feed chain mechanism 5 is carried out so that the rear part of the winding is inclined rearward and upward when viewed from the side, and the axis of rotation is in the width direction of the combine C when viewed from the back and from the front. This is done in a state where it is inclined so that it becomes higher toward the outside, and a transfer path A is formed between it and a pinching mechanism installed opposite to the lower side of the winding.

The clamping mechanism is formed by attaching a clamping rail 13 to the end of the clamping body 11 so as to be swingable about a pivot 12, and the leading end of the clamping rail 13 extends from a fixed member 14. The clamping rail 13 is held in an elastically movable state by a leaf spring 15, and includes a channel-shaped base plate 13a that is appropriately shorter than the end of the feed chain mechanism 5, and a slide body 13b that is slidably fitted into the base plate. The slide body 13b is configured such that the degree of protrusion from the substrate 13a can be appropriately expanded and contracted by a position adjusting and fixing mechanism 13c, and the end portion is positioned closer to the inner wall than the outer wall end 16. The terminal end 17 of the section is formed to be appropriately long.

The rotating wheel front support shaft 18 of the feed chain mechanism 5 located above the straw discharge port 10 of the threshing section 6 has a
Another rotary wheel body 19 is fitted to the outside part, and the transfer chain 21 is wound and hung between the rotary wheel body 19 supported at the tip of the frame 20 extending rearward from the fitted part, and the conveyance chain 21 is discharged. A straw conveying mechanism 22 is provided.

This waste straw transport mechanism 22 is provided with a trapping body 23 on its lower winding side to form a transfer path B that can communicate with the transfer path A. Base gripping body 23 forming the rear half
It is formed by attaching a swinging rod 23b to a.

The positional relationship between the clamping body 23 and the clamping rail 13 of the feed chain mechanism 5 is such that when the swinging rod 23b is in the lowered position, it is supported by the holding portion 24 of the base clamping body 23a and swings together with the base clamping body 23a. When the condition is
Slide body 1 with the tip of the swinging rod 23b in an extended state
3b, the swinging rod 23b swings upward around the attachment part to temporarily release the transfer path B, and locking tool 2
It can be latched at 5.

A waste straw processing device 26 is attached to the lower part of the front part of the transfer path B at the terminal end of the feed chain mechanism 5, that is, to the side part of the straw removal port 10, and its intake port 27 faces upward and forward. The waste straw processing device 26 is opened, and another waste straw processing device 28 is attached to the rear part of this waste straw processing device 26.

In addition, from an appropriate position inside the fixing member of the feed chain mechanism 5, a straw guide body 30 is extended rearward via a position change holder 29, and when the extended portion is in the lowered and held state, the straw guide body 30 is connected to the waste straw processing device. The waste straw is guided to 26.

Further, an elastic guide member 31 is attached to the proximal end portion of the clamping mechanism corresponding to the feed chain mechanism 5 at an appropriate position.
is extended toward the inner rear side of the feed chain mechanism 5 to guide and correct the tip of the waste straw coming out of the straw removal port 10 in a hanging position to a horizontal position.

Next, to explain the operation of the waste straw conveying device configured in this way, when reaping and threshing work is performed by the combine harvester C, the stalk culm group is sequentially pulled up by the reaping and conveying section 3 to be reaped. Then, the stock is placed in a sideways position by the feed chain 4 or the like, and fed so that the tip part is positioned at the supply port and the stock part is positioned at the scraping start end of the feed chain mechanism 5.

The stem culm group supplied to the threshing machine 6 is held at the stock base by the feed chain mechanism 5 and the corresponding pinching mechanism, and is sequentially transferred to the rear along the transfer path A, and the ears are subjected to the threshing action. The straw outlet 1
Due to the resistance caused by the handling action, the group S of shucked straw that is sent out in a sideways position from 0 is slightly behind the tip side in the transport direction than the stock base side supported by the feed chain mechanism 5, and is in a state of hanging downward. It becomes.

Then, at the time when the side closer to the panicle is brought to the straw discharge port 10, the stock side is brought to the pinning rail 13 of the pinning mechanism, and at this time, the side facing the panicle is not discharged from the straw discharging port 10. It is placed on an elastic guide member 31 extending toward the mouth 10 and guided, and is transported while being corrected from the above-mentioned drooping state to a substantially horizontal state. When it reaches the end of the rail 13, its outer side first comes off the end of the outer wall 16 of the clamping rail 13 and is unpinned, and is transferred while being held only by the end of the inner wall 17. As a result, the transfer of the panicle, which has been delayed, is promoted and the posture of the straw group is corrected so that it is parallel to the culm direction.

In other words, the waste straw that had been clamped at the inner and outer wall portions 17 and 16 of the clamping rail 13 in the feed chain mechanism was moved to the designated position before being transferred to the straw transport mechanism. Correcting the transfer delay on the tip side by forcibly transferring the tip side only by the inner wall portion 17 while being in a pinching state only by the inner wall portion 17 of the pinching rail, making it easy to change the posture in the front-back direction, This allows the waste straw to be corrected in its natural posture and transferred to the waste straw transport mechanism without having to forcefully fold it.

The straw group S whose posture has been corrected in this way continues to be transported, but at this time the slide body 13b is reduced and the guide body 30
is in the lowered state and the swinging rod 23b is in the raised and locked state, the group of straw will be moved to the guide body 3.
0 and are sequentially guided to the waste straw processing device 26, or if the waste straw group S is to be processed by another processing device 28, the slide plate 13b
is pulled out and extended, the guide body 30 is raised, and the swinging rod 23b is lowered, whereby the transfer path A is connected to the transfer path B, without causing the waste straw group to reach the processing device 26. The waste straw can be fed to the waste straw processing device 28 from the end of the transfer path B by continuing to take over and transfer the waste straw.

(g) Effect of the invention The waste straw conveying device of the invention works as explained in the above (e), so it does not apply excessive force to the waste straw culm sent from the threshing machine in the front and back directions and in the vertical direction. It has the advantage of being significantly simpler in structure than conventional devices, while being able to smoothly change its posture without having to apply pressure and supply waste straw to the waste treatment device in a good posture.
