Description

[Detailed Description of the Invention] The present invention relates to a structure for a waste straw processing section of a threshing device that is provided with a swingable switching guide for switching and supplying threshed waste straw to a shredding path and a non-shredding path.

With this type, when a blockage occurs in the shredding path and the clogged waste straw is removed, when inspecting the shredding device, move the switching guide to the position where the shredding path is opened. However, in the past, for example, the
As described in Japanese Patent No. 11661, the upper part of the straw removal processing section is covered with a fixed cover, and the edge of this fixed cover is arranged to be aligned with the extension line of the switching guide when the straw removal guiding action is performed. Since it is necessary to allow the switching guide to swing to the open position, it is very difficult to bring the edge of this fixed cover and the upper edge of the switching guide into close contact with each other from a manufacturing and assembly standpoint, and it is difficult to make the straw removal fine. When the shredder is in the working position of guiding the shredder to the shredding path, a gap inevitably appears between the two edges, and as a result, wandering straw gets clogged or caught in the gap, making it impossible to smoothly supply waste straw to the shredding device. During the work, it is often necessary to remove clogged or caught waste straw, and the opening for removing the clogged waste straw is narrow, making removal of waste straw time-consuming and difficult. There was a drawback that it could not be done.

In view of the above-mentioned points, the present invention avoids clogging of the waste straw when the switching guide is placed in a position to guide the waste straw to the shredding path, and also prevents the straw from clogging when inspecting the shredding path and the shredding device. The purpose is to open the area widely and make inspection easier. To achieve this purpose, another guide (second guide) is installed in the cover located above the shredding device around the center of the horizontal axis. This separate guide can be opened together with the switching guide to form a large opening, and when guiding the waste straw to the shredding path, this separate guide can be used to swing the switching guide. It is characterized in that it is configured so that it enters the moving locus and comes into contact with the outside of the free end of the switching guide so that no gap is created between the edges of both guides.

Next, embodiments of the present invention will be described in detail based on the drawings.

A shredding device 2 and a dropper 3 are installed at the rear of the threshing device 1, and threshing waste straw is supplied through a waste straw chain 4, and the waste straw is shredded and released into the field, or it is left in long straw intermittently in a predetermined amount at a time. The waste straw processing section 5
has been constructed.

Covers 6 are provided on both sides, above and behind the shredding device 2.
. . . and both lateral and rear covers 6 . . . are covered with resin, rubber, etc. from the midway point to the lower part, as shown in Fig. 2. An iron plate 8 made of a flexible material with a certain plate 7 fixed with screws is attached to a hinge 9...
The cover 6...
This structure is designed to prevent deformation and damage due to collision with other objects.

A plate-shaped switching guide 10 is pivotally connected to the upper edge of the rear cover 6a so as to be swingable and fixed, and the switching guide 10 is swung to close the upper part of the shredding device 2 and follow the upper surface of the switching guide 10. At the same time, there is a state in which a non-shredding route R1 is formed in which the waste straw from the waste straw chain 4 is supplied to the dropper 3, and a state in which the non-shredder route R1 is crossed and the waste straw is supplied to the shredding device 2. In order to be able to switch the shredding route R2 to a certain state,
Furthermore, the switching guide 10 is swung backward, and the shredding path R2 is
It is configured such that it can be switched to a third position A in which it opens.

A plate-shaped second guide 12 is pivotally connected to the rear end of the top cover 6b around a horizontal support shaft so that it can swing and be fixed, and when the second guide 12 is at its lower swing limit, its free end side is It approaches the upper edge of the switching guide 10 with a portion overlapping in plan view, and swings upward so as to guide the supply of waste straw in both the shredding and non-shredding paths R1 and R2. In the moved state, it is set to a non-guiding action posture and the starting end side portion of the shredding path R2 can be opened.

Reference numeral 13 in the figure is a guide rod that guides from above when supplying waste straw to the dropper 3, and can be inserted into and removed from a bracket 14 connected to the top cover 6b. installed on.

In summary, the feature of the structure of the present invention is that the device enters the swinging locus of the switching guide 10 that switches the conveyance path of the threshed waste straw, and comes into contact with the outside of the free end of the switching guide 10 in the shredding posture. Allows the waste straw guiding action posture in which the waste straw is overlapped and guided to the shredding device 2 in collaboration with the switching guide 10, and the switching guide 10 to swing to the third position that greatly opens the shredding path R2 to the outside. A second guide configured to be able to switch between a non-guiding working position and a dual working position by having its base end swingably attached to the cover unit 6b located above the shredding device 2 around the horizontal axis. It has 12 points, and these unique precepts produce the following effects.

In other words, since the switching guide 10 is brought into contact with the second guide 12 while guiding the waste straw to the shredding path R2, it is possible to avoid creating a gap between the two, and the waste straw can be smoothly cut without clogging. Moreover, since the second guide 12 is provided in a non-guiding position so as to be able to swing freely, it is possible to avoid problems such as when a blockage occurs in the shredding path R2 and needs to be removed, or when inspecting the shredding device 2. Then, the second guide 12 is swung to a non-guiding posture, and the switching guide 10 is moved to a third position A different from the above-mentioned switching between the shredding state and the non-shredding state.
By swinging, the shredding route R2 and the parts near it can be opened wide, making it easier to remove clogged straw from the shredding route R2 and inspect the shredding device 2, compared to the conventional structure mentioned at the beginning. This has made processing work much more efficient.
