Relative rotation occurs with the connecting block 503, and then the left turning block 509 drives the left transition frame 502 and the screen 501 to rotate relative to one end of the base 1 through the right turning block 509, and the screen 501 shakes back and forth, The screening of rapeseed can be accelerated, and the rapeseed will fall to the inside of the collection hopper 7 through the screen 501, and impurities such as chaff and branches will fall to the second collection on the right along the screen 501 and the transition frame 502 on the right. In the box 12, when the rapeseed inside the collecting hopper 7 does not pass the first humidity sensor 615, the first humidity sensor 615 will detect the humidity of the rapeseed. When the detected humidity does not meet the humidity requirements, the control cabinet 2 controls the first humidity sensor 615. The alarm light 13 alarms the outside world, and then the staff controls the second electric telescopic rod 10 through the control cabinet 2 to drive the guide bucket 9 and the baffle 8 to move to the left, so that the outlet of the collecting bucket 7 is connected to the guide bucket 9, and the staff The cover 612 is removed from the top of the ventilation cylinder 611, and the feeding port of the ventilation cylinder 611 is on the top, then the rapeseed inside the collecting hopper 7 will fall to the inside of the ventilation cylinder 611 through the guide hopper 9, and the rapeseed inside the collecting hopper 7 will fall to the inside of the ventilation cylinder 611. After falling, the baffle plate 8 is reset, and the staff continues to add rapeseed to the inner side of the upper hopper 401, and continues to screen the rapeseed. Then the staff resets the end cover 612, and then the control cabinet 2 controls the second motor 616 to drive the ventilating cylinder. 611 rotates, while the ventilation cylinder 611 rotates, the rapeseed will be lifted to a high place through the inner lifting plate 617, and the rapeseed will fall from the high place. The hot air quickly dries the rapeseed through the ventilation tube 611, and the filter screen 609 filters the dust inside the production workshop. When the humidity of the rapeseed inside the ventilation tube 611 reaches the requirement, the second humidity sensor 11 will be controlled by the control cabinet 2. The second alarm light 14 alarms the outside, reminding the staff to process the rapeseed inside the ventilation cylinder 611 in time, and then the second motor 616 drives the end cover 612 to be on the top through the ventilation cylinder 611, and the second motor 616 stops Work, then the worker removes the end cover 612, and then turns the ventilating cylinder 611 so that the outlet of the ventilating cylinder 611 faces down, and then the rapeseed falls to the bottom end of the processing box 601, and then the worker removes the door panel 602 through the handle 603, and then The staff takes out the rapeseed, and when the screen 501 needs to be replaced, the staff pulls out the limit pins 511 at both ends from the inside of the transition frame 502, and then removes the transition frame 502, so as to realize the replacement of the screen 501. It is easy to disassemble and operate. When replacing the new screen 501, follow the opposite steps. When the filter 609 needs to be replaced, the staff takes out the limit plate 608 from the inner side of the card holder 607, and then the filter 609 will be in the Under the action of the second spring 613, a part of the drying shell 604 is ejected, and then the staff can take out the filter screen 609. When reassembling, follow the opposite steps.
