Description

[Detailed explanation of the invention] Conventionally, a swinging sorter was installed in the sorting air passage from the bottom of the receiving screen in the handling room, through the dust sorting room, and through the dust outlet at the rear to make the grains leak out and to air-sort them. That is already known.

When the amount of grain is large compared to the amount of straw waste, such as in rice, the mesh leakage sorter facing the first receiving trough is fully utilized and the sorting wind blows from the bottom to the top, and the second sorter is It is desirable to stand up the receiving plate installed at the end to prevent the grain from scattering.Also, in cases where a large amount of straw is generated, such as in wheat, where the amount of grain is relatively small, a mesh leakage is required. Blocking a part of the lower sorting body or reducing the sorting wind that blows through to suppress leakage and prevent cut straw from getting mixed in with some grains, and the receiving plate to lie down to promote release of straw waste. is desirable.

If the leakage area of the mesh leakage sorter described above is changed or the wind direction plate and receiving plate for adjusting the sorting air are adjusted separately, the structure becomes complicated and the work becomes complicated. This results in drawbacks such as the need to provide windows for inserting hands during adjustment at the portions of the front wall facing the wind direction plate and receiving plate.

The present invention is capable of performing leakage sorting and wind sorting that are most suitable for the threshing conditions, and is also capable of good discharge of straw waste and prevention of scattering, and is simple in structure and easy to operate. The present invention aims to provide a very simple sorting device for a threshing machine, in which the receiving screen in the handling room is connected to a sorting air path from below, through the dust sorting room, to the dust exhaust port, with a transfer sorting device facing below the receiving screen. A board, a mesh-like leakage sorting body extending to the end of the plate and facing the top of the first receiving gutter, and a mesh-like leakage sorting body extending to the end thereof and facing the second receiving gutter on the lower side, and allowing the second material to leak while transferring straw waste. In a threshing machine equipped with a swinging sorter consisting of a sorter whose terminal end faces a dust exhaust port, a horizontal shaft supported on the side plate of the swinging sorter is installed at the lower part of the mesh leakage sorter of the swinger. A wind direction plate is provided that rotates around the center, and a receiving plate is provided at the end of the second sorting body that rotates around a horizontal shaft supported on the side plate of the oscillating sorting body, and the above-mentioned wind direction plate and the receiving plate are connected to each other as a wind direction plate. When the wind direction plate approaches the mesh leakage sorter, the receiving plate lowers, and when the wind direction plate tilts downward, the receiving plate rises. The receiving plate is configured to be lowered.

The present invention will be explained in more detail with reference to the drawings below. Reference numeral 1 denotes a handling barrel that is mounted on a shaft in a handling chamber 2. A feed chain 3 and a sandwich rail 4 are provided along the handling opening, and a receiving net 5 is provided. The part extending from the bottom to the dust removal chamber 6 and the dust removal lower at the rear is formed into a sorting air passage 9 by a pressure wind turbine 8, and the swinging sorter 10 installed in the sorting air passage 9 is made of A transfer sorting plate 10a having a step-like shape, a sorting net 10b extending to the end thereof and facing the first receiving gutter 11, and the first flow plate 10c,
It is composed of a sheave 10d with a rack that extends further rearward of the rising part 10c' at the end of the first flow plate 10c and faces above the second receiving gutter 12, a second original plate 10e, etc.
A second thrower 13 is provided on the opposite side of the second receiving gutter 12 from the handling opening, and its discharge port 13a opens into the second reducing passage formed between the receiving net 5 and the mechanism. The second return passage communicates with the transfer and sorting plate 10a.

Further, a suction windmill 14 is provided on the same side as the feed chain 3 in the upper part of the dust sorting chamber 6, and a No. 4 funnel 15 is provided in front of the suction windmill 14.

The side plate 1 between the sorting net 10b and the partial flow plate 10c
Wind direction plates 17 are installed in the water holes 16 and 16 drilled at 0' and 10'.
A horizontal shaft piece 18°18 protruding from both sides of is fitted loosely,
A square hole 19a provided at the bent part of the L-shaped arm 19 is fitted into the square column part 18' at the outer end of one horizontal shaft piece 18, and fixed with a screw 19a'. A plurality of adjustment holes 20 (19b) are formed in the side plate 10'.
Select one of them to match, and then press washer 2.
1, inserting thumbscrews 22 and screwing them onto fixing nuts 23, the wind direction plate 11 can be placed in a position in which the sorting air is blown upward as shown in FIG. 2, and in a sorting net as shown in FIG. The position is changed to be in contact with the lower surface of 10b and close the mesh, and to an appropriate position intermediate therebetween.

Furthermore, at the end of the second original plate 10e, the lower part of the receiving plate 25 is connected in a hinge-like manner by a support rod inserted through the holes 24 of the side plates 10' and 10', so that when the receiving plate 25 is rotated backward, it collapses. Then, when it rotates forward, it stands up.

Further, on the front surface of this receiving plate 25, there is a sub-plate 26 which can be adjusted up and down by means of a pole 27.27 inserted into the elongated hole 25a of the receiving plate 25 and a wing screw 28.28 screwed thereto. As shown, the storage position can be adjusted so that it does not obstruct the discharge of straw waste.

By adjusting the vertical movement of the sub-plate 26, it is possible to prevent scattering according to the amount of straw waste.

The small hole 19c at the rear upper end of the arm 19 is rotatably engaged with the front end of the connecting rod 29, and the rear end of the connecting rod 29 is connected to the elongated hole 30 bored in the side plate 10'. After inserting it into the receiving plate 2
It is inserted into a small hole 31 at the side end of 5 and fixed with a nut 33 via a bullet 32.

Therefore, when the arm 19 is adjusted in tilt, the receiving plate 25 rises and falls in conjunction with the tilt adjustment.

In addition, 34 in the drawing is a straw chain, and 35 is the second original plate 10e.
It is a rubber plate that slides into contact with the bottom surface of the

In the above-mentioned device, the threshed medium grains and small straw waste generated in the handling room 2 leak from the receiving net 5, and the cut ears, long straw, etc. fall from the dust outlet 36 and are transferred to the transfer sorting plate 10a. When the grains reach the sorting net 10b, the lower grains and small straw waste leak out, and some of the grains slide down on the flow plate 10c and fall into the first receiving gutter. The straw waste is blown away by the sorting wind from the upper air path X.

The straw remaining on the sorting net 10b is thrown onto the rack-equipped thief 10d, the second straw slides down on the second original plate 10e and falls into the second receiving gutter 12, and the straw waste is sent backward by the rack. The dust is discharged outside the machine from the dust exhaust port 1.

In addition, the straw and dust floating in the dust sorting room are removed by the suction windmill 14.
It is sucked and discharged from.

If the grains to be threshed are comparatively large in grains and there is little straw waste, such as in the case of rice, there is a window 3 provided in the mechanism □ as shown by the dotted line in the diagram.
After removing the lid 7, insert your hand and set the wind direction plate 17 so that the sorting air blows upward as shown in FIG.

In this state, the screening net 10b performs leakage screening over its entire surface, and the screening air actively blows through the mesh of the screening net 10b, removing straw waste from the material on the screen, so that the grains leak well.

In addition, in the rack-equipped sheep 10d, there is relatively little straw waste, and the mixed grains are not scattered outside the machine by the sorting wind in the lower air path y, but the receiving plate 25 is Since it stands up, it prevents the above-mentioned scattering.

Furthermore, when there are relatively few grains and a lot of straw waste during threshing, such as wheat, on the other hand, the wind direction plate 17 is used as a sorting net 1 as shown in FIG.
If it is brought into contact with the lower surface of 0b to reduce its leakage area, there will be fewer grains, so even from the narrowed sorting net 10b, sufficient leakage will occur and the mixing of cut straw will be prevented. Therefore, it does not become an obstacle to the discharge of straw waste, and the amount of straw waste can be discharged quickly and smoothly by at most 1@.

As mentioned above, the present invention has a sorting air path extending from the bottom of the receiving screen in the handling room, through the dust sorting room, to the dust exhaust port, and a transfer sorting plate facing below the receiving screen, which is extended to the end of the screening air path. A shaker consisting of a mesh-like leakage sorting body that faces above the catch gutter, and a sorting body that faces the second gutter on the lower side and allows the second thing to leak while transferring straw waste, and whose end faces the dust exhaust port. In a threshing machine equipped with a movable sorter, a wind direction plate is provided at the lower part of the mesh leakage sorter of the oscillating sorter, which rotates around a horizontal shaft supported on the side plate of the oscillating sorter; At the end of the sorting body, there is provided a receiving plate that rotates around the horizontal shaft No. 77 supported on the side plate of the swinging sorting body, and when the wind direction plate approaches the mesh leakage sorting body, the receiving plate rotates between the wind direction plate and the receiving plate. When the wind direction plate descends and the wind direction plate tilts downward, the receiving plate is linked and connected so that it rises, and when there is little straw waste, the receiving plate is raised, and when there is a lot of straw waste, the receiving plate is lowered. When adjusting the rotation of the wind direction plate according to the type or condition of the culm, the distance between the wind direction plate and the receiving plate is always constant no matter where the swinging sorter is located, and the two are smoothly interlocked and rotated. Moreover, when there are few grains and a lot of straw waste during threshing, when the wind direction plate is rotated upward, the receiving plate is rotated downward in the opposite direction, and the flow is removed from the mesh leakage sorter. leakage is suppressed, thereby preventing cut straw from getting mixed into the grain, and at the same time making it possible to smoothly discharge straw waste, reducing the amount of second material, which makes it easier to sort. It is possible to improve performance.

In addition, when there are relatively many grains and little straw waste during threshing, rotating the wind direction plate downward will improve the leakage of grains and prevent grains from getting mixed into the second grain and causing damage. can,
There is relatively little straw waste on the sorting body facing the second receiving gutter, so the grains mixed in are not scattered outside the machine from the dust exhaust port by the sorting wind, but the receiving plate is raised and oscillates. While swinging integrally with the sorting body, the grains to be scattered are received and collected in the second receiving gutter, thereby reducing the time required for the third scattering of grains.
