Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rough sorting section for receiving a processed material which has leaked from a handling room and swinging and transferring it, and swinging a sorted processed material which has leaked from this rough sorting section. A coarse sorting section is provided with a fine sorting section that causes the grains to be sorted and leaked to the first one collecting section while being transferred, and the second one is dropped onto the second collecting section that is arranged on the lower side in the transfer direction. The present invention relates to an oscillating sorting device in a threshing device in which a Straw rack for receiving the discharged straws and discharging the straws is disposed on the lower side in the transfer direction of the fine sorting unit.

2. Description of the Related Art In the rocking sorting apparatus of the above threshing apparatus, conventionally, as disclosed in, for example, Japanese Patent Application Laid-Open No. 4-75533, a fine selection consisting of a Glen pan and a Glen sieve is provided below a Straw rack type rough sorting section. There is a separate part that is equipped with a fixed glensive and a slidable movable gren pan, and the movable glen pan is slid to change the leakage area of the glen pan according to the difference in throughput. It was Further, there is also a configuration in which the rough sorting section is constituted by a chaff sheave whose leakage opening can be changed, and a fine sorting section is arranged below it.

[0003]

According to the first conventional structure, the leakage area of the Glenpan is variably adjusted according to the amount of threshing treatment so that the leakage area is increased when the treatment amount is large. In this way, it is possible to reduce grain loss by performing sufficient leakage selection, and to prevent the cut waste from being mixed into the first product recovery section as much as possible when the processing amount is small. However, in the above-mentioned conventional structure, since the structure of the rough sorting unit is of Strawac type, there is a high possibility that a large amount of broken chips will be mixed in the leakage processing product from this rough sorting unit, and especially the processing amount. When the grain size becomes large, the amount of straw waste increases, and when the leaking area of the Glensieve is increased, there is a disadvantage that these straw wastes are most likely to be mixed into the object recovery section. Therefore, if the leaked area of the grain sieve is changed to a small side in order to eliminate such a problem, there is an adverse effect such that the grain is discharged and the loss becomes large. In the above-mentioned second conventional structure, by changing the leakage opening of the rough sorting section to the closed side according to the throughput, it is possible to prevent the fall of straw debris into the fine sorting section as much as possible. Then, there is a drawback that the processed material is likely to be deposited on the rough sorting portion and clogging occurs early. Incidentally, as a method of preventing the above-mentioned harmful effects, it is possible to increase the processing leakage area in the rocking sorting device, but if this is done, there is a drawback that the threshing device becomes large and the cost becomes high. . An object of the present invention is to provide a rocking / sorting device in a threshing device capable of improving the threshing treatment performance while having a compact shape without increasing the size of the device.

[0004]

The features of the present invention are as follows:
The rough sorting section is composed of a chaff sheave whose leakage opening can be changed and adjusted, and a fixed Glen pan that is fixed in position in a swing sorting case at an upper and lower intermediate position between the rough sorting section and the fine sorting section. A movable gren pan that is vertically slidable on the fixed gren pan and is slidable along the workpiece transfer direction; and a plurality of sieve lines arranged in parallel on the lower side of the movable gren pan in the transfer direction along the transfer direction in a cantilever manner. And the tip of the sieving line is arranged to be close to the Straw rack in a sliding state in which there is little overlap between the movable Glen pan and the fixed Glen pan.

[0005]

[Operation] When the threshing treatment amount is small, the leakage opening in the chaff sieve type rough sorting section is changed to the closed side to prevent straw dust from leaking downward from the rough sorting section as much as possible. In addition to that, by sliding the movable Glen Pan to a position where there is less overlap margin with the fixed Glen Pan, and increasing the effective length of specific gravity difference selection by the Glen Pan section,
Straws are effectively removed, and straws are oscillated and transferred from the tip of the sieving line to the Straw rack, and mainly only the grain leaks to the fine sorting section below, and the grain collecting section It is possible to prevent straw dust from mixing in. Also, when the threshing treatment amount is large, the leakage opening in the chaff sheave type rough sorting unit is changed to the open side, and the movable Glen pan is slid to a position where the overlapping margin with the fixed Glen pan is large, While smoothing the leakage of the processed material in the sorting section and minimizing the retention of the processed material in the rough sorting section, the sieving by the sieving line effectively removes the scraps to the precise sorting section below. Means that the treated products are sorted and leaked with a small amount of straw scraps.

[0006]

EFFECTS OF THE INVENTION Therefore, by reasonably improving the structural structure, it is possible to prevent straw dust from leaking onto the fine sorting part as much as possible without increasing the sorting leaking area, regardless of the difference in the threshing treatment amount. While reducing the risk of straw debris mixing in the grain recovery unit, it is possible to sort and discharge straw debris effectively not only in the precise sorting unit but also in the intermediate unit, even when the processing amount is large. As a result, it is possible to effectively prevent the harmful effects such as the loss of the grains mixed with the straw waste and discharged to the outside of the machine body, and the sorting efficiency can be improved.

The screening mechanism 17 is configured by arranging a plurality of sieving lines 25 arranged in parallel in a cantilevered state. The movable grain pan portion 24b and the sieving line 25 are integrally slidable in a direction along the workpiece transfer direction,
When the movable grain pan portion 24b is slid to the upper side in the processed material transfer direction, the fixed margin pan portion 24a and the movable Glen pan portion 24b are overlapped with each other, and the transfer length of the Glen pan portion is shortened so that the leakage of the processed material is smooth. When it is slid in the opposite direction, the overlap margin is reduced, and the tip end of the sieving line 25 comes close to the second Straw rack 23, and the working length of the Glenpan portion becomes long, and the specific gravity difference sorting is performed. The amount of slide and the length of extension are set so that the waste scraps are effectively discharged to the outside of the machine body through the second straw rack 23 while sufficiently performing the above.

That is, when the processing amount is small, the opening of the chaff sheave 19 is narrowed to prevent straw debris from leaking to the fine sorting unit 16, and the movable Glen pan portion 24b is slid to the lower side in the transfer direction to lengthen the Glen Pan portion. In this way, the specific gravity difference is sufficiently sorted, and the scraps are controlled to be discharged onto the second Straw rack 23. Further, when the processing amount is large, the opening degree of the chaff sheave 19 is widened to prevent the processed material from staying, the movable grain pan portion 24b is slid upward in the transfer direction, and the Karato wind amount is changed to the large side. It is controlled so that the straw dust is effectively blown off to the lower side and the grain can be efficiently collected in the fine sorting section 16.
