Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cover device for a culm conveyor installed in a threshing machine such as a combine harvester or a harvester.

[Problems to be solved by the prior art and the invention] Generally, this type of waste culm transporter is designed to transport the threshed waste culm towards the rear post-processing section. A cover body is provided separately because if the conveyance route on the plant side side of the waste culm conveyed by the conveyor body is not covered in any way, the dust will scatter violently and it is dangerous. However, if the cover body is located outward from the end of the stock, the width of the aircraft will become wider and the aircraft will become larger, which is undesirable.
As shown in Publication No. 134651 and Japanese Utility Model Application Publication No. 149061/1987, the cover body has an upper edge screwed onto the fuselage side so that it can be opened and closed outwardly, or a cover body whose front end is pivoted and can be raised and lowered. There are also known devices that can swing.

However, the waste culm conveyor is deviated toward the already cut field side so that the waste culm does not come into contact with uncut culms and is disturbed, or the waste culm discharged outside the machine in the previous work process is not traversed by the crawler. It has become possible to transport it while doing so. Therefore, in the conventional method mentioned above,
It is not possible to sufficiently cover even the culm which has become large and voluminous due to the shedding of the stock, and when the culm from which the stock has fallen out is sent to the mown field side, the bulge is attached to the lower edge of the cover. When the cover body was caught, it was often forcibly pulled into the mown field, causing the cover body to break inward and cause damage. So Mikiakiaki
As shown in Publication No. 57-54249, it has been proposed to vertically install a vertically long cover body on the culm root side conveyance route from the upper end edge to the lower end edge of the route. Since the weight of the body is heavy, when the amount of culm is small, the resistance between the base of the culm and the cover body becomes large and the culm becomes disordered, which makes it impractical. Ta.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a cover device for a culm transporter that can eliminate these drawbacks. To the outside of the culm conveying body that conveys the culm that has been removed to the rear post-processing section side, from the upper edge of the transfer route to block the transfer route on the plant base side of the culm being conveyed by the culm conveying body. When the cover body extending to the lower end edge is installed vertically, the upper end edge of the cover body is pivotally supported on the upper side of the culm transporting body, and the lower end edge is located at a vertical midway position on the culm root side transport path. A first cover that can swing outward, an upper edge of which is pivotally supported by the lower edge of the first cover, and a lower edge of which is located at the lower end of the culm root side transfer path, and which is positioned relative to the first cover. and a second cover that can independently swing outward, and furthermore, the lower end of the second cover is bent outward and upward.

With this configuration, the present invention can open and close in stages depending on the amount of culms, and even if the culms have fallen out and have become huge at the base of the culm. The cover body can be transported without getting caught on the lower edge of the cover body when being pulled into the mowed field.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawing, reference numeral 1 denotes a traveling machine of a combine harvester, and the traveling machine 1 has a structure that is inclined toward the already cut field side in order to transfer the waste culm that has been threshed in the threshing section 2 toward the post-processing section 2a. A culm transporting body 3 is provided, and a culm transporting body 3 is provided on the plant head side of the waste culm transporting body 3 in order to block the transport route of the waste culm from the upper edge to the lower edge. A cover body 5 in which the present invention is implemented is disposed on the starting end side of the conveyance body 3, that is, from the transfer site from the feed chain 4 to the conveyance terminal end to the post-processing section.

In other words, in this embodiment, the cover body 5 includes a first cover 8 which is screwed onto the outer end of a cover 6 that covers the threshing section and the ceiling of the culm transporting body 3 via a support shaft 7; The first cover 8 is composed of two upper and lower covers, and a second cover 10 is screwed onto the lower edge of the cover 8 via a support shaft 9. It is located midway in the vertical direction with respect to the transfer route of the culm stock base, and is free to swing outward by coming into contact with a regulating part 6a bent and formed on the outer edge of the cover 6. However, inward rotation is now restricted. In addition, the second cover 10 has its lower edge hanging down to reach the lower end position of the culm conveyance path, and comes into contact with the regulating part 8a bent at the outer edge of the first cover 8, so that the second cover 10 is independent. Although it is free to swing outward, inward rotation is restricted. Moreover,
The lower end edge 10a of the second cover 10 is largely bent outward and upward, so as to prevent the base of the culm from getting caught on the tip edge.

In the embodiment of the present invention configured as described above, the waste culm that has been threshed in the threshing section 2 is transported rearward while being sequentially transferred to the already cut field side by the waste culm conveyor 3. It will be post-processed by 2a and discharged outside the machine.

When the culm is transported by the culm conveyor 3, the transport route on the side of the culm stock base is blocked by the cover body 5, but in this case, in the present invention, The cover body 5 is divided into two upper and lower stages consisting of a first cover 8 and a second cover 10, and these covers 8 and 10 swing independently around the support shafts 7 and 9, respectively. When the amount of discharged culms to be transported is small, only the lower second cover 10 opens outward to cover the plant side of the discharged culms, and when the amount of discharged culms is large, the upper second cover 10 opens outward. The first cover 8 is also opened together with the second cover 10 to cover the root side of the culm.

In this way, in the present invention, the cover body 5 has a stepwise covering action by the first cover 8 and the second cover 10, depending on the amount of discharged culms to be transported. The heavy cover body can be swung outward even when the amount of discharged culms is small, such as when the conventional cover body is configured in a single piece that is vertically long from the upper end to the lower end of the plant base conveyance path. This reliably prevents the culm from being disturbed due to increased conveyance resistance between the culm and the cover body.

Moreover, in the present invention, the lower end portion 1 of the second cover 10
0a is greatly bent outward and upward, and the part where the culm touches is curved without any catch, so as the culm is transported, it is sequentially transferred to the mowed field side. However, it goes without saying that the stock part of the culm will not get caught in the second cover 10, and even if the stock part of the culm is missing a temporary stock and the stock part has expanded greatly, this The ampulla does not get caught on the second cover 10 and the second cover 10 is not forcibly drawn inward, and the cover body 5 expands upward and only the culm is drawn inward. Therefore, damage caused by being drawn inside the second cover 10 can be reliably prevented.

It should be noted that the present invention is of course not limited to the above embodiments, but for example, the cover body 5 may be
The conveyance start end side is swingably supported by a support shaft 11, and the guide rod 13 at the conveyance end side is inserted into the elongated hole 12 so as to be vertically movable.
The base side of the culm may be covered by the opening and closing of the upper and lower covers and the vertical movement of the cover body itself around the support shaft 11, and the second cover may be made of one piece. Rather, if necessary, it may be divided into two pieces in the vertical direction, or it may be divided into more pieces.

[Operation and Effect] In short, the present invention is configured as described above, so that when the amount of culm discharged is small, the first cover on the upper side remains in a drooping state, and only the second cover on the lower side hangs down. opens independently to the outside, and when the amount of discharged culms is large and the base of the discharged culm is above the conveyance path, the second cover and the first cover on the upper side are to be opened together to the outside. As for the cover body that blocks the plant side conveyance route, when the amount of discharged culms is small, only the second cover on the lower side is opened, and when there is a large amount of discharged culms, the first and second covers are opened. Therefore, it is necessary to perform a covering action on the side of the expelled culm base according to the amount of expelled culms. Even if the amount of culms is small, opening the entire cover body that is long in the vertical direction will not cause the base of the culm with a small number of culms to receive conveyance resistance based on the weight of the entire cover body in the open state, and the amount of culms can be reduced. When the amount of culm is small, only the lower second cover opens accordingly, and the conveyance resistance received from the cover body becomes smaller. The paper can be smoothly transported to the post-processing section in an orderly manner without causing the paper to be disorganized.

In addition, the lower end of the second cover is bent outward and upward, so even if the culm has fallen out and the plant base has become large and voluminous, when it is transported backwards, When drawn inward,
This prevents the cover body from getting caught and being forcibly pulled inward and causing damage, and an ideal cover action can be achieved.
