Description

[Detailed Description of the Invention] The present invention relates to a device for promoting husk supply and sorting in a lower-class threshing machine.

In other words, in conventional threshing machines, when the husks are fed from the feed port, the culm side is clamped by a foot chain and forcibly fed sideways, but the ear side does not have a feeding device and is then planted in the handling barrel. Because this depends on the arrangement of the handling teeth provided, the grain is fed laterally than the culm side, and is subject to the thrashing action of the handling teeth, which has the disadvantage of increasing the occurrence of ear breakage and straw waste.

In addition, the material that has been threshed in the handling room and passes through the receiving net is transferred to the opposite side from the oscillating sorting body Hafeet Chain, which takes over and sorts the material by centrifugal force and wind generated by the rotation of the handling cylinder. The particles were mainly caught and could not be evenly distributed on the upper surface of the oscillating sorting body, resulting in insufficient sorting action.

Therefore, in view of the above points, the present invention solves these conventional problems, thereby efficiently performing the threshing process in the handling room, and making it possible to effectively sort the material to be handled by this threshing process. It is an object of the present invention to provide a low-grade threshing machine that can perform good threshing and sorting by combining tightening and sumo.

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

FIG. 1 shows a cross-sectional view of a part of the threshing machine, in which a supply lower is provided at the lower side of a handling chamber 3 in which a handling barrel 8 is installed.

A crimp net 9 is stretched around the lower part, and a dust inlet 10 is provided at the lower part on the straw exhausting side, and a straw exhausting outlet 11 is provided on the side of the dust inlet 10.

A swinging sorter B is installed extending from the lower part of the handling room 3 to the sorting and dust removal chamber 12 at the rear of the machine. Net 15. It is configured to have a straw rank 16, a winnower 17 is installed below the grain feeding plate 13, and a No. 1 conveyor 18 is installed below the sorting net 15.
are installed respectively, and a No. 2 conveyor is installed below the stroke rank 16.

A shell culm clamping and transferring device A consisting of upper and lower foot chains 1 and clamping rods 2 is installed outside the handling opening 19 formed along one side of the handling chamber 3.

A suction machine C equipped with an impeller 21 rotated by a pulley 20 is fixedly installed in the lower part of the culm clamping transfer device A near the supply lower side, and a net presser 22 and a clamping machine are installed below the handling port 19. The lower part of the dust suction path 23 that opens between the rod 2 is vacuumed by a suction machine C.
The lower part of the dust suction path 24 communicating with the suction port 4 is configured to communicate with the upper part of the grain feeding plate 13 of the oscillating sorting body B below the crimp net 9.

Further, a supply plate 25 is provided that extends from below the supply lower part to the front side, and the supply plate 25 is moved on the supply plate 25 and becomes closer to the tip side of the culm that is supplied to the supply lower part. A low step part 26 is formed in the part, and the exhaust passage 5 on the exhaust side of the suction machine C is made into a pipe structure, extending at the lower end of the supply plate 25, and the end of the exhaust passage 5 is formed into a pipe structure. The end port 6 is connected to the low step portion 26, and the exhaust air from the end port 6 is configured to flow from the low step portion 26 onto the supply plate 25 inwardly of the supply lower.

During threshing work, the culm side of the shell culm is pinched and transferred by the shell culm clamping and transferring device A, and the tip side is transferred to the supply plate 2.
5, the exhaust air from the suction device C is discharged from the tip port 6 to the tip side, which tends to be delayed.
It is sent out and blown as shown by the arrow in the figure, and due to the exhaust wind, the tip side is sent to the supply lower, the direction is sent to the strong direction, and the direction is transferred to the culm side into the handling chamber 3. It is promoted to catch up, and there is no occurrence of breakage of the ears or generation of large amounts of straw waste, which is caused by the tip side being delayed and laterally fed as in the past.

In addition, the above-mentioned exhaust air is blown toward the tip side to reduce the wind speed, and most of the dust that is collected during the exhaust air is circulated in the handling chamber 3 as the handling teeth rotate, and then the dust is sent. A portion of the liquid is discharged from the port 10 and leaks through the crimp net 9.

On the other hand, in the handling chamber 3, the wind pressure increases due to the rotation of the handling cylinder 8 and the handling teeth, and in particular, the centrifugal force and wind generated by the rotation of the handling teeth cause the unprocessed material to be pushed between the husks on the grain feeding plate 13. The material to be handled is mainly caught on the side opposite to the grip transfer device A, but due to the suction force of the suction device C, the suction force directed toward the suction port 4 as shown by the arrow in FIG. The dust is attracted to the gripping transfer device A side and distributed almost evenly on the grain feeding plate 13, and some of the dust is also sucked into the suction machine C together with the dust blown out from the handling port 19.

In this way, the present invention has a shell culm clamping transfer device A side VC consisting of a foot chain 1 and a clamping rod 2, and a suction port 4 of a suction machine C above the swinging sorting body B below the handling chamber 3. are provided so as to communicate with each other, and the tip opening 6 of the exhaust passage 5 of the suction device C is connected to the
Since the supply lower is configured to have an opening near the tip side so that air can be discharged toward the inside of the handling chamber 3, air can be discharged from the tip port 6 toward the tip side of the culm that is supplied to the supply port T. This allows forcible feeding to catch up with the feed on the culm side and allow the feed to be fed crosswise through the handling chamber 3 from the supply port T, thereby reducing the generation of large amounts of broken ears and straw waste. Therefore, it is possible to reliably and effectively supply the product without any problems.

In addition, the material to be handled passing through the crimp net 9 from the handling chamber 3 is transferred to the culm clamping transfer device A of the oscillating sorting body B by the rotation of the handling drum 8.
However, the suction force of the suction device C draws them together and distributes them approximately evenly, making the sorting action effective.

It is also hygienic because the dust blown out of the machine from the handling opening 19 is sucked into the suction machine C.
