Description

[Detailed Description of the Invention] The present invention relates to a straw removal side structure of a handling chamber in a bottom handling type threshing machine.

That is, in the conventional bottom-handling type threshing machine, as shown in FIG. Therefore, when the straw is discharged from below the handling barrel 4 through the straw discharge port 2, the upper surface of the straw is removed from the space between the lower edge 3b of the outlet side plate 3 and the upper surface of the straw. The disadvantage was that dust and other substances were deposited on the grains, resulting in a large amount of grain being taken out.

The present invention solves these drawbacks, eliminates the need to carry out dust, etc., allows the abrasive grains to fall well, and provides a simple structure that can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

In Figures 1 to 3, Figure 1 shows a side sectional view of a bottom handling type threshing machine mounted on a combine harvester;
A feed chain 6 and a culm 7 are installed above and below the outer side of the handling chamber 1 in which the handling barrel 4 is housed to form a lower handling type threshing section. A crimp net 9 is installed at the bottom of the handling chamber 1, forming the straw opening 2.
A crimp net 9 is installed at the bottom of the terminal side of the handling chamber 1.
An adjacent dust inlet 5 is formed downwardly at the end of the dust outlet 2 with a partition plate 10 interposed therebetween, and a No. 4 gutter 11 is installed outside the dust outlet 2 with a little difficulty. 1
The lower edge 3a of the outlet side plate 3, which is the upper edge of the straw outlet 2 formed at the straw outlet side end, is formed lower than the conventional type so that it coincides with the lateral side of the outer peripheral surface of the handling barrel 4, The front part A extending toward the lower side of the feed chain 6 from the middle part of the lower edge 3a is straight and inclined, and the rear part B extending rearward from the middle part of the lower edge 3a is horizontal and straight. It is formed and configured so that it extends.

From the lower part of the handling chamber 1 to the rear sorting and dust removal chamber 12, there is a grain sieve 13 and a stroke rack 14.
A vibrating sorter A equipped with
6, the No. 2 conveyor 17 etc. is arranged, and the No. 4 gutter 1
A straw removal chain 18 that takes over the waste straw from the feed chain 6 and carries it out extends from above the feed chain 1 to the rear of the machine.

Therefore, during the threshing operation, the grain culm, which is conveyed through the culm side by the feed chain 6, is threshed in a lower handling manner by the handling cylinder 4, and the grains, etc. leak through the crimp net 9, and With the waste falling downward from the dust inlet 5, the straw that reaches the end of the handling chamber 1 passes along the outer periphery of the lower part of the handling barrel 4, passes through the straw outlet 2, and enters the No. 4 gutter. However, when the straw passes through the straw outlet 2, the upper surface side of the straw comes into contact with the lower edge 3a of the outlet side plate 3. There is no dust etc. on the waste straw, and due to the contact, the waste straw becomes wavy and the prickly grains in the waste straw fall.

In this way, the present invention has a structure in which the lower edge 3 of the outlet side plate 3 serves as the upper edge of the straw outlet 2 formed at the straw outlet side end of the handling chamber 1.
a is formed low so as to match the lateral side of the outer peripheral surface of the handling barrel 4, so that the upper surface side of the straw discharged from the handling chamber 1 through the straw discharge port 2 is the lower edge 3a of the outlet side plate 3. Because of the contact with the waste straw, there is no dust etc. on the upper surface of the waste straw as in the conventional method, and due to the contact, the waste straw is undulated and the grains can be dropped smoothly. It has the advantage of being able to be implemented conveniently with a simple structure.
