Description

[Detailed description of the invention] Conventionally, as shown in Fig. 4, a swinging sorting device for a thresher consists of an original plate with a high supply port side and a low discharge port side below the lower screen of the handling room, and a corrugated plate extending from the lower end of the original plate. It is already known to have a sorting plate facing out and a sorting net extended to the tip of the sorting plate (culm opening).

However, when wet husk is threshed during or after rain when there is morning dew, the waste that leaks from the netting under the handling room adheres to and accumulates on the raw plate, forming clumps and forming wavy shapes. Falling onto the board, the transport speed temporarily decreases, which causes a thick layer of trench\
Since the straw was fed into the sorting net, the amount of straw waste blown through the sorting net was significantly reduced, and the amount of straw waste blown by the sorting wind was not well discharged.

In addition, the lumped material is transferred in a thick layer over the sorting net, and when it is thrown from the tip of the sorting net onto the second receiving gutter, the material on one end of the screen touches the tip of the sorting net. It gets stuck between the first plate and the original plate, significantly reducing the sorting function, and a large amount of straw waste also falls into the second receiving gutter, which clogs the second thrower and makes it impossible to recover.

In order to eliminate this drawback, as shown in Figure 5, the tip of the corrugated plate is formed low, a sorting net is extended to the lower end, and the perforated plate a is punched from the high end of the corrugated plate. If they are arranged in series to prevent cut straw A and relatively large straw waste from falling onto the sorting plate, and to allow grains and small straw waste to leak out,
If the hole diameter is small, not only will wet straw waste block the punched hole, but in order for the grains to leak out completely, the punched perforated plate a must be made quite long, which will cause the casing and leakage. If the punching hole is made larger to improve the quality of the material, the straw A will fall in an upright position, and its lower end will get stuck in the mesh of the sorting net. The disadvantage is that the movement of the air and the blow-through of the sorting air become worse.

Also, as shown in Figure 6, if a number of spokes b are protruded from the tip of the corrugated plate so as to face the upper surface of the sorting net at appropriate intervals, this can be done in cases where the materials to be sorted are transferred in layers. Although there is a certain degree of separation effect, when the amount of material to be handled decreases at low efficiency, the cut straw A falls in a vertical position and gets stuck in the sorting net B, or the cut straw falls from the sorting net and becomes the first grain. There is a drawback of mixing.

The purpose of this invention is to improve the above-mentioned drawbacks.
In a threshing machine, a swing sorting body consisting of an original plate facing below the lower screen of the handling room and lowered on the lower side in the transfer direction and the first grain flow sieve etc. connected to the tip of the original plate is installed. The bases of a large number of parallel spokes spaced apart in the width direction of the machine are fixed to the spanning board so that wedge-shaped gaps are formed between them, so that the board objects are dispersed while sliding down on the original board. The present invention is also characterized in that the cut straw is laid down as much as possible along the transport direction.

The present invention will be described in more detail with reference to the embodiment shown in the drawings below. Reference numeral 1 denotes a handling cylinder which is mounted on a handling cylinder shaft 1a in a handling chamber 2, and a feed chain 4a is attached along a handling opening 3. and a support rail 4e are arranged side by side, and a lower screen 5 is stretched on the lower surface of the handling room 2.

Reference numeral 6 denotes a winnow provided below the supply port 1, and the portion extending from the bottom of the lower screen 5 to the dust removal chamber a is formed into a sorting air passage 8 in a direction parallel to the handling cylinder axis 1a.

1 includes an eccentric wheel 10a and a swing link 10 in the sorting air passage 8.
b is a swinging sorting body that sorts plate products while swinging and transferring them in a direction parallel to the handling cylinder axis 1a, and includes a spanning board 9a that faces below the lower screen 5 and is lower on the lower side in the transport direction, and its tip. Sorting net (or sheep) 9 constituting the sieve sorting body extended to
b, the first original plate 9c facing the first receiving gutter 11 from the front end of the sorting net 9b, and the sorting net 9b from directly below the dust inlet 13 formed by cutting out the outlet 12 side of the lower screen 5. It is provided with a transfer plate 9d extending from the middle part to above the tip side, and a large number of parallel spokes 9e and 9e' are connected to the tip of the transfer plate 9d and the first original plate 9c.

The bases of a large number of spokes 15, which are substantially parallel to the handling trunk axis 1a and are spaced at appropriate intervals in the machine width direction, are fixed to the intermediate portion of the spanning plate 9a facing directly below the lower screen 5. , the spokes 15 are sloped more gently than the spanning board 9a in order to form a wedge-shaped gap between them and the spanning board 9a, and their tips are above the discharge port of the winnowing winnow 6 like the transfer plate 9d. It faces onto the sorting net 9b at a portion that intersects with the extension line of the edge.

In the above-mentioned apparatus, when the stock part of the culm is clamped and conveyed by the feed chain 4a and the fusei rail 4b, and the sugar part is inserted into the handling chamber 2 from the supply port I and threshed, the grains in the plank are transformed into small straws. Together with the waste, it falls from the lower screen 5 onto the original plate 9a, and flows down while being subjected to layered sorting with grains as the lower layer, and midway through the flow, it rides on the spokes 15, and is subjected to rocking motion while being transferred, thereby forming a shell culm. The wet and lumpy straw is loosened and coarsely sorted, and the grains are transferred and spread on the gangplank and fed onto the sorting net 9b, and the straw waste falls onto the grains. , Kiriwara A has two or more spokes 15
...While you are straddling the top, you will not fall, but while receiving the swinging action, your posture will change, and one end will become the spoke is, is
When it falls onto the original plate from the gap, it flows downward and ends up lying on its side during that time and transfers to the sorting net.

The grains being sent onto the sorting net 9b and being threshed leak out of the sorting net 9b and are wind-selected at the same time and fall directly or through the first original plate 9c into the first receiving gutter 11, and are transferred into a spiral. 11a
It is discharged outside the machine.

On the other hand, straw waste and the like on the sorting net 9b are discharged to the outside of the machine via the dust removal chamber a by the sorting wind blowing through the sorting net 9b.

On the other hand, the grains with twigs that have not leaked from the cut straw A or the sorting net 9b are transferred to the spokes 9e' on the second receiving gutter 14, but in the meantime, the cut straw A is transferred onto the sorting net 9b. Since the grains are transported on their sides, they do not get stuck in the mesh and interfere with transport, and the grains do not fall off and get mixed with the grains.

In addition, large pieces of straw, ear pieces, etc. in the handling chamber 2 are discharged from the dust outlet 13 onto the transfer plate 9d, where they are separated by the wind and the spokes 9e.
Some of the grains, ears of ears, short cut straw A, etc. that are mixed in after being sorted through the oscillating sieve leak onto the sorting net 9b, and are further sorted through the sieve as described above, resulting in large straw waste and straw. Cuts, ears, etc. are transferred onto the second receiving trough 14 and sent there.

Furthermore, large pieces of straw that have not leaked from the spokes 9e are discharged by the spokes 9e, and in the meantime, the ear cuttings and the like that have not yet leaked are transferred to the second original plate 16a.
