In FIG. 1, the configuration of the self-propelled self-escape device will be explained.

A threshing device, an engine room 29, etc. are mounted on a crawler-type traveling device 35. A frame is protruded to the left side of the threshing device, and the grain culms are collected here and fed to the feed chain 25. While being held by the feed chain 25,
The tip portion passes through the handling chamber A, and the waste straw is sent in the direction of the straw removal chain. The threshed grains are sorted, and the fine grains are first collected on the conveyor 22, and then transferred to the hoisting cylinder 26.
The engine enters the storage tank 27 from the inside and is placed in an engine room 29 which is housed in a grain bag on a bag holder 28.

The present invention relates to sorting of the processed filtrate of the processing cylinder 6 in such an overall configuration.

Fig. 2 and Fig. 3 will be explained together.

The handling cylinder 7 rotates on the handling cylinder shaft 12, rotates between the receiving net 13 and the handling chamber cover, and forms a handling chamber A between the receiving net 13 and the handling chamber cover. .

A processing cylinder 6 is arranged parallel to the processing cylinder 7 and on the opposite side to the feed chain 25. 1
4 is a processing cylinder axis. Furthermore, a suction chamber D constituted by a suction fan, a suction port 8, and a rotating plate 8a are configured outside the processing chamber B.

The processing chamber B and the handling chamber A are separated by a partition wall 18. Two openings are provided in the partition wall 18, one on the inlet side and the other on the outlet side.

Reference numeral 18a is a return spout from the No. 2 swallow 20, through which the straw-mixed grains thrown up by the No. 2 swallow 20 are thrown into the handling chamber A.

Reference numeral 18b is a processing chamber opening, and materials such as straw waste produced in the handling chamber A that do not pass through the receiving net are thrown into the processing chamber B through this opening.

In the processing chamber B, processing teeth are arranged so that the material to be processed is sent in the opposite direction from the exit side to the inlet side, and the straw-adhered grains are shed and the grains are sent to the processing chamber receiving screen 15.
falling from. A straw waste discharge port 15a is provided at the processing end of the processing chamber, and straw waste that does not pass through the receiving screen 15 is discharged onto the oscillating sieve line 2 from here. The straw waste sent to the rear without passing through the oscillating sieve wire 2 is sucked into the suction chamber D through the suction port 8 and discharged.

And, in this invention, between the processing chamber B and the suction chamber D,
A "V"-shaped partition plate 1 is arranged. The processing chamber B side of the partition plate 1 is the hanging part 1a, and the suction chamber D
The side serves as the wind guide portion 1b.

The "V"-shaped partition plate 1 is first arranged to hang downward at the hanging part 1a, and from above the extension line of the inclined flow grain plate 9 of the oscillating sorting device C, the suction port 8 of the suction chamber D and the turning plate are placed. It is bent toward 8a to form the air guide portion 1b of the partition wall plate 1.

The oscillating sieve line 2 is arranged approximately horizontally, protruding from the terminal end of the oblique flow grain plate 9 of the oscillating sorting device C, and below the air guiding portion 1b.

That is, the sorting air flowing along the lower surface of the grain plate 9 is blown so as to sort and send the material on the oscillating sieve line 2 to the suction port without disturbing the flow. be.

In short, the present invention suppresses and controls the wind so that the straw waste and straw-attached grains on the oscillating sieve line 2 are not blown up or blown back.

The oscillating sorting device C is supported and suspended by oscillating links 30 and 31 at the lower part of the receiving net 13 in the handling room, and oscillates by integrating the sorting plate 11, grain grain board 9, sorting net 10, etc. are doing.

The fine grains that have fallen from the receiving net in the processing chamber B are heavy, and fall onto the flow board 9 and enter the oscillating sorting device. 2
fall on top. The straw-adhered grains that have been sorted by the oscillating sieve line 2 and have fallen are collected from the second stream grain board 17 onto the second conveyor 23, and then sent to the second thrower 20 into the handling room A.
will be reduced to

In the oscillating sorting device C, the sorting plate 11 and the sorting net 1
The fine grains that have been sorted at 0 and fell out are transferred to the first flow grain board 1.
6, the grains are first collected on the conveyor 22 and sent to the frying cylinder 26.
It is stored in a bag.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, the extending direction of the grain plate of the swing sorting device,
Since the air guide portion 1b of the partition wall plate 1 is arranged in a straight line, the flow of the sorting air can be given directionality, and the objects to be sorted can be unevenly distributed on the oscillating sieve line, unlike conventional methods, or can be swept up and returned. This solved the problem that was having a negative impact on the flow of straw waste.

Secondly, since the oscillating sieve wire 2 is oscillated so as to intersect with the directional sorting wind, the objects to be sorted are subjected to wind pressure in the direction of being sent to the suction port, so that the sorting is always carried out in a fixed direction. Since the particles are sorted by the wind, the sorting accuracy can be improved.

Thirdly, since the air guiding portion 1b of the partition wall plate 1 is provided on the extension line of the inclined flow grain plate 9, the air path of the sorting air does not suddenly widen at this portion, and a stall state of the sorting air occurs. I stopped doing it. This also contributes to improving the sorting performance.
