Description

[Detailed description of the invention] [Field of industrial application] This invention is used for a sorting device in a threshing machine, and in particular, it is used for a sorting device in a thresher. This relates to a transfer sorting device installed on the opposite side.

[Conventional technology]

In the transfer sorting device configured as described above, a plurality of stroke racks or spokes are provided rearwardly extending from the tip of the transfer sorting plate, and the dust discharged from the dust outlet is received at the starting end of the dust sorting plate. The waste is then sent to the rear stroke rack or spoke, where it is oscillated and sorted to allow the second material to leak out, and the third material is discharged to the outside of the machine through a dust sorting room. There is.

[Problem that the invention attempts to solve]

However, when a stroller rack or the like is installed extending from the tip of the transfer sorting plate, large and small treated materials are mixed and moved to the stroke rack all at once, making it difficult to sort out leakage. ,
For example, if the distance between the stroke racks is set narrowly, the second product will not leak easily, and the third product containing a large amount of grains will be ejected outside the machine. There was a defect in which a lump of dust particles fell and increased the amount of secondary reduction.

The technical problem of this invention is to reduce the amount of secondary reduction and prevent the scattering of grains by separating the large particles in order and separating mixed grains from waste as quickly as possible. It is to do so.

[Means for solving problems]

The sorting device according to the present invention, which was adopted to solve the above problems, is as follows.

are erected at appropriate intervals in the lateral direction, and a base is attached to the tip of the transfer and sorting plate 20 between the stroke racks 22, so that the starting end is against the upper edge of the stroke rack 22 when viewed from the side. The stroke rack 22 is inclined upwardly, and spokes 23 are provided along the slope of the stroke rack 22 from the middle to the rear.

[Effect]

The dust discharged from the dust port 6 is sorted by specific gravity into large and small particles and grains on the upper transfer sorting plate 20, and then transferred.First, the upper large layer is transferred from the tip of the sorting plate 20 to the handling chamber. It is placed on the starting end of the upper stroke rack 22 inserted into the second side, separated from the lower layer, and oscillated rearward. Relatively small lumps and grains are further oscillated and transferred on the transfer sorting plate 20 between the stroke racks 22 and separated, reaching the tip of the plate. It is transported upward while being supported by the starting end,
The grains are transferred backwards while merging with the grains being transferred on the stroke rack 22, and fall from the end of the transfer sorting plate 20 onto the sorting net 15 and are collected in the first receiving trough 17.

〔Example〕

An embodiment of the present invention will be described based on the drawings. Reference numeral 1 is a handling chamber of a threshing machine, which is mounted on a shaft between a front wall 3 and a rear wall 4 of a handling chamber 2 provided at the front of the machine.
Reference numeral 5 denotes a receiving screen extending below the handling room 2, and 6 indicates a dust inlet opening at the terminal end of the receiving screen 5.

Reference numeral 7 denotes a feed chain disposed on the side of the handling chamber 2. The grain culm supplied to this feed chain is threshed while passing through the handling chamber 2 from the supply port in the front wall 3, and is passed through the feed chain from the discharge port in the rear wall 4 to the feed chain 4. It is designed to be discharged to the port 8.

A ventilation fan 9 is installed below the starting end of the handling room 2, and a dust sorting room 10 is installed at the rear of the handling room 2 via the fourth port 8. Mouth 12 is open. 11 is the dust sorting room 10
This is a suction type dust removal fan that is connected to and installed on the outside.

A swinging sorting body 13 is provided in the sorting chamber formed between the blower fan 9 and the lower part of the dust sorting chamber 10.
is installed so that it can swing freely in the front and rear directions. 13a are left and right frames of the swinging sorter 13.

To explain the oscillating sorter 13 in detail, 14 is a lower transfer plate facing below the receiving net 5; 15 is a lower transfer plate 1;
4 is a sorting net extending from the end of the first return plate 16 toward the top of the first return plate 16, and the lower end of the first return plate 16 is the first receiving gutter 17.
It is facing upward. Further, at the upper end of the first return plate 16, there is a lower stroke rack 1 facing above the second gutter 18.
9 has been extended.

Reference numeral 20 denotes an upper transfer and sorting plate whose starting end faces downward from the dust inlet 6, and the entire plate is inclined rearward upward, and the front part thereof is a corrugated non-perforated plate 21 provided with a row of lateral protrusions.
A plurality of upper stroke racks 22 are erected at appropriate intervals in the lateral direction, and their starting ends are located at positions that enter the handling chamber 2 from the tip of the corrugated non-perforated plate 21. The tip faces the lower part of the dust sorting chamber 10.

23 is a spoke installed between the upper stroke racks 22, the base of which is attached to the flat part 31a at the tip of the non-perforated plate 21, and the starting end inclined upward with respect to the upper edge of the upper stroke rack 22. ,
The rear part from the middle part is formed to follow the slope of the upper stroke rack 22, and extends to a position where the tip thereof almost coincides with the tip of the upper stroke rack 22.

Reference numeral 24 denotes an adjustable wave plate provided below the wave type non-perforated plate 21, and pins 24a protruding left and right from this plate are passed through long holes 13b in the front and back direction provided in the frame 13a of the swing sorting body 13. By moving the rod 25 engaged with the pin 24a in the front-back direction, the adjustable wave plate 24 can be moved in and out of the front and back to adjust the substantial length of the wave-shaped non-perforated plate 21. ing.

Incidentally, since the mounting base of the spoke 23 is mounted on the flat part 21a at the tip of the corrugated non-perforated plate 21,
The material to be sorted moving backward on the corrugated non-perforated plate 21 can move smoothly without being caught by the spokes 23. Moreover, the adjustment wave plate 24 is made by superimposing it below the wave type non-perforated plate 21 with a slight step difference,
This makes it possible to obtain a good sorting condition.

The present invention is constructed in this manner, and the grains and small debris that have been dropped by the handling drum 1 and leaked from the receiving net 5 fall onto the lower transfer plate 14 of the oscillating sorting body 13 and are transferred to the rear. The grains are sorted on the sorting net 15 by the sorting air that can be drawn through the screen, and the grains are discharged outside the machine through the dust sorting chamber 10, and the grains are collected in the first receiving trough 17.

Long straw and lumps containing grains that did not leak through the receiving net 5 become dust and fall from the dust inlet 6 to the starting end of the upper transfer sorting plate 20, and are transferred to the corrugated non-perforated plate 21. By gravity sorting, long straw and lumps are separated into the upper layer, and grains are separated into the lower layer while moving to the lower layer.

When these dust particles reach the starting end of the upper stroke rack 22, the straw and large lumps of the upper layer are first caught on the rack 22 and separated from other materials to be processed, and the upper edge of the rack 22 is separated. and transported backwards.

On the other hand, the remaining relatively small lumps, grains, etc. do not rest on the upper stroke rack 22, but pass between them and are oscillated and separated on the corrugated non-perforated plate 21 before reaching the end thereof.

Then, the grains fall onto the sorting net 15 while being screened at the end of the corrugated non-perforated plate 21, and relatively small debris and some lumps are placed on the slightly upwardly sloped part of the starting end of the spoke 23. When the straw is pushed forward by the following one and reaches the part along the upper edge of the upper straw rack 22, from there it is swung backward as the large lumps and straw on the rack 22 move.

In this way, the objects to be treated are separated step by step, starting from the largest one.

In addition, the large lumps placed on the upper straw rack 22 are crushed by the swinging transfer action of the rack during movement, and the grains and small debris mixed therein are separated and transferred to the upper or lower straw of the sorting net 15. Rack 19
Leak above. The remaining items are dispersed and moved backwards, and are subjected to wind separation near the end of the upper stroke rack 22. The third item is discharged outside the machine via the dust sorting chamber 10, and the second item is It falls and is collected into the second receiving gutter 18 via the lower stroke rack 19. Further, the starting end of the upper stroke rack 22 enters into the handling chamber 2 side, and the effective sorting length is correspondingly longer, so that grains will not be mixed into the third product.

Furthermore, small lumps on the spokes 23 are
The grains are crushed while being oscillated and transported by the large lumps moving on the upper stroke rack 22, and the grains and the like mixed therein are separated and leaked out. The remaining part (third part) is sucked and discharged near the end of the spoke 23.

[Effect of idea]

The upper stroke rack 22, whose starting end is inserted into the handling chamber 2 side from the tip of the upper transfer sorting plate 20, first separates large lumps from the dust to make it easier to separate relatively small objects. Since the grains are further oscillatedly transferred on the upper transfer sorting plate 20 between the upper stroke racks 22, most of the grains mixed in the small lumps are separated and the grains are transferred to the sorting plate 20 between the upper stroke racks 22.
Most of the grains fall at the end of the spoke 23, and the remaining relatively small debris and some lumps are supported by the starting ends of the spokes 23 and transported upwards, and are transported on the upper stroke rack 22. Since the grains are transferred to the rear while merging with the grains, it is possible to reduce the number of grains that fall into the second place, and to minimize the amount of grains that get mixed into the third place. In addition, since larger lumps can be sufficiently separated and separated by the long stroke rack 22 whose starting end is inserted above the upper transfer and sorting plate 20, the above effect is further enhanced.
