According to a third aspect of the present invention, in the invention according to the first or second aspect, a space between the first receiving net and the swing sorting plate is formed in a leakage space of the reprocessed material. There is to be.

[0008] The feature of the invention according to claim 4 is the invention according to any one of claims 1 or 2,
A second reduction device configured to form a second reduction passage along the front and rear sides of the first processing cylinder on a lateral outer side opposite to the handling cylinder, and to bounce and discharge the second processing material. The outlet
From the rear end side of the first processing cylinder, facing the entrance of the second reduction passage, the first receiving net is directed upward along the peripheral surface of the first handling cylinder in a state of facing the second reduction passage. It has been extended.

According to a fifth aspect of the present invention, in the invention according to any one of the first, second, third and fourth aspects, the first processing cylinder and the second processing cylinder are shifted left and right. It is in.

According to a sixth aspect of the present invention, in the invention according to any one of the first, second, third, fourth, and fifth aspects, a third rotating member is provided around the left-right axis behind the handling chamber.
A processing cylinder, and a guide portion for guiding a non-leakage material discharged from a rear end side of the first processing cylinder and the first receiving net to the third processing cylinder, and performs a process of sorting the non-leakage material. And it is constituted so that it may be discharged to the rear part of the swing sorting plate.

According to the structure of the first aspect, the processed material reaching the second half of the handling chamber enters the first processing cylinder side and is handled and processed, and the grains and the like are shaken through the first receiving net. Leakage etc. leaks onto the moving sorting plate, and the straw chips and the like exit from the first processing cylinder and the rear end side of the first receiving net. The second processed material from the second reduction device enters the second processing cylinder side and is handled and processed. Grains and the like leak onto the oscillating sorting plate via the second receiving net, and straw waste and the like are removed from the second processing drum side. 2 It exits from the processing cylinder and the rear end side of the second receiving net.

That is, since the processed material on the second half side of the handling room, which contains a large amount of waste chips, is reprocessed by the first processing cylinder and the first receiving net, for example, the rotation speed of the first processing cylinder and the first processing cylinder By setting the processing conditions of the processed material, such as the volume of the processing cylinder and the first receiving net, so as to match the properties of the processed material, the kernels can be easily collected, and the load on the handling cylinder can be reduced. It can be reduced and the processing capacity of the handling cylinder can be increased. And, since the second processed material is handled and processed by the second processing body side and subjected to leakage sorting by the second receiving net, even if it is paddy mixed with straw waste or paddy with branches, the grain is reduced to straw waste. It can be easily separated and collected from the branches.

According to the second aspect of the present invention, in addition to the same effect as the operation of the first aspect, the main receiving network stretched opposite to the handling cylinder can be provided by the second processing cylinder. Because it extends upward along the peripheral surface of the handling cylinder so as to face the space above the main net, it is necessary to increase the leakage area of the main receiving net and improve the leakage performance of grains from the main receiving net Can be. Further, by forming the space above the second processing cylinder, the pressure in the handling room can be reduced, and similarly, the performance of leaking kernels from the main receiving net can be improved.

Since it extends upward along the peripheral surface of the first handling cylinder so as to face the passage, the leakage area of the first receiving net is increased, and the leakage performance of the grains from the first receiving net is increased. Can be raised. Further, fine processed products such as grains leaked from the portion of the first receiving network facing the second reduction passage are blown off toward the first half of the handling room by the discharge air flowing through the second reduction passage, and the fine processed products are shaken. It is possible to lengthen the distance for the dynamic sorting and prevent it from being immediately discharged from the rear end of the handling room.

According to the configuration of claim 5, in addition to the same operation as the operation of any one of the first, second, third, and fourth aspects, the main receiving network / second receiving network can be provided. The processed material that has leaked from the network / third receiving network is difficult to mix,
Grains etc. can be prevented from accumulating unevenly on the swing sorting plate,
It is possible to prevent the recovery rate of the grain from becoming uneven in the width direction of the swing sorting plate.

According to the structure of claim 6, in addition to the effect of the structure of any one of claims 1 or 2, 3, 4, and 5, the first processing cylinder and The non-leakage material discharged from the rear end side of the first receiving net is guided by a guide portion to a third processing cylinder rotating about the left and right axes, and the non-leakage material is sorted and oscillated. The discharge to the rear of the plate increases the sorting accuracy.

[Effect] Therefore, according to the structure of claim 1,
The sorting accuracy was improved and the grain recovery rate was increased.

According to the structure of claim 2, in addition to the effect similar to the effect of the structure of claim 1, it is possible to improve the performance of grain leakage from the main receiving net. As a result, the grain recovery rate could be further increased.

According to the structure of claim 3, in addition to the effect similar to the effect of the structure of claim 1 or 2, the leakage performance of the kernel from the first receiving net is improved. And the grain recovery rate could be further increased.

According to the structure of claim 4, in addition to the same effect as the effect of any one of the above-described claims 1 and 2, and in addition to the effect of the kernel from the first receiving net, Leakage performance can be improved, and the distance from which small processed materials such as grains that have leaked from the portion facing the second reduction passage of the first receiving net are rocked and selected is increased, and from the rear end of the handling room Since it can be prevented from being discharged immediately, the recovery rate of the grain can be further increased.

According to the structure of claim 5, in addition to the same effect as the effect of any one of claims 1 or 2, 3, and 4, the width of the swing sorting plate in the width direction can be obtained. Thus, it is possible to avoid unevenness in the recovery rate of the grains, so that the recovery rate of the grains can be further increased.

According to the configuration of claim 6, in addition to the same effect as the effect of any one of the above-described claims 1, 2, 3, 4, and 5, the first processing cylinder and The non-leakage material discharged from the rear end side of the first receiving net is guided by a guide portion to a third processing cylinder rotating about the left and right axes, and the non-leakage material is sorted and oscillated. Since it was discharged to the rear part of the plate and the sorting accuracy could be increased, the recovery rate of the grain could be further increased.
