Description

  The present invention relates to a carrier driving device in a combine.

Conventionally, in order to improve the threshing performance and sorting performance, the dust feeding mouth processing cylinder is arranged in parallel on the side of the rear part of the handling cylinder, and the branch rachis adhering grains etc. that could not be processed by the handling cylinder are sent to the processing cylinder, Of the grains to be processed in the threshing section, usually 10-15% of the grains are made into a single grain and discharged through the processing net onto the swinging sorting device of the lower sorting section.
Further, the second thing after the grain is sorted by the sorting device from the grain and sawdust flowing down from the threshing section is sent to the branch raft processing device via the second conveyor and the second reduction conveyor, After removing the branches and the like by the processing device, the processing is again returned to the sorting start portion of the swing sorting device.

  However, if the amount of threshing processing increases due to the speed and efficiency of the combine unit, the processed material in the dust inlet processing cylinder will be rough, the filtration of the processing cylinder will be worsened, and the amount of emissions outside the machine will be reduced. Even if it increases or is filtered on a rocking sorter, the discharge from the third port to the outside of the machine increases without being filtered by a chaff sheave or the like, and it is difficult to achieve a normal single granulation rate. In particular, since a large amount of grain concentrates just below the dust-feed port processing cylinder, there is a case where the swing selection is poor.

Therefore, the applicant can reduce the grain loss from the third exit, etc., and can effectively increase the grain by effectively utilizing the sorting width of the swing sorting device. Receiving the processed material that is below the dust feeding port processing cylinder and discharged from the dust feeding port processing cylinder, and transporting the processed material in a direction opposite to the direction of feeding the crushed material by the dust feeding port processing cylinder. Proposed to have a carrier to be discharged onto the rocking sorter of the part.
