The threshing device has a processing cylinder 8 arranged in parallel with the handling cylinder 7, and the second reduced product returned to the processing cylinder 8 from the second reduction thrower 12 is threshed again by the processing cylinder teeth 8a. It is processed and returned to the handling cylinder 7. The grains that have been threshed in the handling chamber in which the handling cylinder 7 is arranged pass through the crimp net 13 and fall onto the swinging sorting device 16, where they are sorted by the swinging sorting device 16 and are also subjected to swinging sorting. While falling from the sorting net of the device 16, the fine particles are sorted by the sorting air generated by the sorting fan 15, and enter the first container 14.
Immature grains, grains with husks and ears, etc. fall onto the second conveyor 10. The No. 2 reduced material that has fallen onto the No. 2 conveyor 10 is thrown up by the No. 2 reduction thrower blade 11, and
It is fed into the processing cylinder 8 from the second reduction thrower 12.

In the threshing device of this embodiment, a sieve wire 23 is arranged at the terminal end of the oscillating sorting device 16, and the straw waste and grains with ears that do not pass through the sieve wire 23 and reach the terminal are removed. They are placed on the orthogonal processing cylinder 9 placed above the number conveyor 10. Processing teeth 9a are installed in the orthogonal processing cylinder 9, and between the processing teeth 9a and the rack sieve 24, the grains are again threshed, and the threshed grains fall into the second conveyor 10.

In this embodiment, by arranging the orthogonal processing cylinder 9, a large amount of dust is generated especially in the suction space C, and the processed materials input from the swing sorting device 16 to the orthogonal processing cylinder 9 are unevenly distributed. There is a tendency for the sorted materials to mainly concentrate on the terminal end side of the orthogonal processing cylinder 9, and dust and straw are also unevenly distributed along with them. -B is made different on the left and right sides. As shown in FIG. 3, the feed direction of the processed material by the orthogonal processing cylinder 9 is toward the side where the processing cylinder 7 and the feed chain are located, as shown by arrow M, and vice versa.
The feed direction of 0 is toward the processing cylinder 8 where the second reduction thrower 12 is located. Therefore, more dust is generated on the left side in the direction of travel where the suction dust ejector B is attached, and there are also more items to be sorted on this side, so the sorting fan 15
The sorting air is obstructed by the processed material and difficult to reach.
The suction and dust removal device B has a larger suction capacity and is placed further forward and lower than the suction and dust removal device A.

In addition, the size of the dust and straw differs depending on the left and right side of the threshing device, and the right side with suction dust removal device A has more fine-grained dust, while the left side with suction dust removal device B has more dust. There will be more coarse straw waste.

このような事情から、該吸引排塵装置Bを吸引排塵装置

For this reason, the suction dust removal device B is arranged below and in front of the suction dust removal device A, and its suction capacity is increased.

該構成は、第2図において、吸引排塵ファン1のファン

This configuration can also be understood from the fact that in FIG. 2, the fan shaft 1a of the suction and dust removal fan 1 is located further forward and lower than the fan shaft 2a of the suction and dust removal fan 2.

With the above configuration, the dust and straw generated by the handling cylinder 7, the swinging sorting device 16, the orthogonal processing cylinder 9, and the processing cylinder 8 fly up and enter the suction space C, and then the The dust is suctioned in a well-balanced manner by the dust removal device A and suction dust removal device B, and is dropped onto the field through the discharge ports of the fan cases 3 and 4.

In the present invention, the discharge directions of the fan cases 3 and 4 are further directed to different directions for each of the suction and dust removal devices AB. 5 is a large force pulley of the suction dust removal fan 1, and 6 is an input pulley of the suction dust removal fan 2.

First, as shown in Fig. 3, the suction and dust removal devices A-B are installed separately on the left and right sides of the side plate of the thresher, but since the suction and dust removal fan 2 has a strong blowing force,
The straw and dust spread out on the way to the field and are scattered almost over the width of the combine. In this scattered state, most of the dust and straw waste discharged from the suction dust removal device on the right side are light (and small), and these dust and straw waste are discharged from the suction dust removal device B on the left side, which is large and heavy. If it is placed on top of the waste, the field will look ugly after the work is completed.

In the present invention, in order to improve this point, the fine-grained dust discharged from the suction dust removal device A on the right side is dropped first, and then the dust is covered with large and heavy straw etc. This is a large piece of straw falling from the suction and dust removal device on the left.

(F) Effects of the Invention Since the present invention is constructed as described above, it exhibits the following effects.

First, since the suction dust removal device A-B, which suctions and removes the dust in the threshing device mounted on the combine, is placed on the left and right sides of the suction space C of the threshing device, the inside of the threshing device is inevitably biased to either the left or the right. It has a suction power that always maintains a balance between the left and right suction when suctioning straw and dust, which is a win.
The left and right suction dust exhaust fans 2 can be set, and a sufficient air volume can be obtained to suction fine particles and dust, without creating a space where suction cannot be performed.

Secondly, the dust removal capabilities of the suction dust removal devices A and B of the 2 Mi were made different, and the dust removal directions of both suction and dust removal devices A and B were also made different in the vertical direction, so that the straw dust was mainly collected. (And by placing the suction dust removal device B, which discharges large and heavy straw waste, facing upward, the dust of the large and heavy suction dust removal device B can be blown as far as possible, and the direction slightly downward. Light dust and straw debris from suction dust removal device A placed in the field can be quickly removed, and then covered with the dust emitted from suction dust removal device B, so that the appearance of the field after harvesting is not unsightly. It is possible to do this.
