Description

[Detailed explanation of the idea] The present invention relates to a threshing dust removal device for a threshing machine.

In other words, the cross-flow fan body can be used as a handling cylinder for threshing, and the grains generated in the handling room can be smoothly sent to the processing room at the rear using wind power for good processing, and light straw waste can also be handled by wind power. The straw can be easily discharged directly from the chamber to the outside of the machine, reducing the amount of straw that falls from the handling room or processing room, improving the sortability below, and reducing the amount of straw that is sent to the processing room. Therefore, the processing performance is improved, the threshing dust can be removed well, and the structure is simple and can be suitably implemented.

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

FIG. 1 shows a side sectional view of a part of the threshing machine, in which a swinging sorting body 8 is extended from below the crimp net 7 stretched at the lower part of the handling chamber 2 to the dust exhaust side, and is installed at both ends of the handling chamber 2. A supply port and a straw discharge port are formed on the side, and a grain culm insertion port 9 is formed in the front side of the handling chamber 2, and a feed chain 10 and a trapping rod 11 are provided above and below the outside of the insertion port 9.
It is constructed in the same way as the conventional structure by installing horizontally.

A handling cylinder consisting of a cross-flow fan cylinder A is mounted in the handling chamber 2, and the cross-flow fan cylinder A has disks 14, 15 are fitted and fixed, respectively, and both ends of blades 16 extending in the axial direction are fixed to the inner surfaces on the outer peripheral sides of both plates 14 and 15, and a large number of blades 16 are similarly arranged in series at regular intervals, Feather 1
Both ends of the handling teeth 1 protruding outward are connected between 6 and 16, and a large number of handling teeth 1 are implanted on the outer periphery.

The cross-flow fan body A can also be constructed by horizontally disposing a support frame between the blades 16 disposed in the same manner as described above, and by implanting the handling teeth 1 on this support frame.

Further, a communication port 17 is formed at the rear of the handling chamber 2 on the opposite side of the insertion port 9, and behind the lower part of the communication port 17, the upper part is open and a crimp net 18 is formed at the lower part.
A processing chamber 3 is formed, in which a lower part of the processing chamber 13 is connected to an upper part of the swing sorting body 8, and processing teeth 19 are implanted on the outer peripheral surface of the processing chamber 3. The processing cylinder 4 is rotatably mounted on an axis, and the communication port 1
A dust evacuation chamber 5 is formed above the processing chamber 3 so as to communicate with the upper part of the dust evacuation chamber 7 and the upper part of the processing chamber 3, and a dust evacuation path 20 extends downward from the rear of the dust evacuation chamber 5. At the same time, a downward dust exhaust port 6 that opens to the outside of the machine is formed at the lower end of the dust exhaust path 20.

During the threshing operation, a cross-flow fan body A rotating as shown by arrow A is used to lower the grain culms that are supplied into the handling room 2 and transported by the feed chain 10 and the trapping rods 11. Treated tooth 1
As a result, the lower crimp net 7
The grains, etc. that leaked out fall onto the oscillating sorter 8, and the cross-flow fan body A rotates so as to suck air from the grain culm insertion port 9 side and exhaust the air to the communication port 17 side. Heavy ears of ears, etc. are sent downward, and light straw waste, etc. are sent upward from the communication port 17 along with the exhaust air.
The ears of ears, etc. sent out as shown by the arrow (B) enter the processing chamber 3, are processed by the processing teeth 19 of the processing cylinder 4, which rotates as shown by the arrow (C), and the grains, etc. leak through the crimp net 18. The heavy ears of rice among the light straw waste, etc., fall onto the oscillating sorter 8 and are sent from the communication port 17 to the dust removal chamber 5 as shown by the arrow D. Light straw debris in the dust exhaust chamber 5 falls as shown by the arrow and is sent out through the dust exhaust port 6 by the exhaust air from the cross-flow fan body A, as shown by the arrow. It will be ejected from the aircraft.

Therefore, the straw waste generated in the handling chamber 2 is discharged to the outside of the machine from the dust exhaust port 6, reducing the amount of straw to be processed in the treatment chamber 3.
There will also be less straw debris falling.

In this way, the present invention has a handling cylinder consisting of a cross-flow fan cylinder with handling teeth implanted on its outer periphery, which is mounted on a shaft in a handling chamber, and a processing chamber that communicates with the rear of the handling chamber and is open from above. The cylinder is mounted on a shaft, and a dust exhaust chamber is formed above the processing chamber to communicate with the handling chamber and the processing chamber, and a dust exhaust port that opens to the outside of the machine is formed on the rear side. Splinters and straw waste generated indoors can be smoothly sent out to the rear processing room and dust removal room using the cross-flow fan body.
Heavy grains, etc. are effectively processed in the processing chamber below, and light straw waste is efficiently discharged from the dust chamber to the dust exhaust port, reducing the amount of waste to be processed in the processing chamber. The processing performance is improved, and there is less straw waste during sorting as it falls downward, improving sorting performance.Threshing dust can be removed well, and the structure is simple and can be carried out conveniently. have
