s2: when the incomplete worm (4) rotates, the worm wheel (12), the transmission shaft (6), the net barrel (7) and the material pushing plate (24) are driven to slowly rotate, and the material pushing plate (24) slowly pushes rice in the storage barrel (1), so that the medicine smell is more uniformly distributed;
s3: the motor (3) is turned off, the threaded rod (20) is rotated, the threaded rod (20) drives the baffle plate (21) and the partition plate (17) to move towards the right side when rotating, at the moment, the through hole (22) on the left side of the partition plate (17) is gradually moved out of the gas collecting tube (9), the through hole (22) on the right side of the partition plate (17) enters the discharging tube (8), the partition plate (17) respectively pulls the barrel cover (15) and the sealing cover (16) through the traction rod (18) and the ejector rod (19), so that the barrel cover (15) tilts towards the left side and is separated from the left end of the gas collecting tube (5), the sealing cover (16) downwards seals the gas inlet at the right end of the gas collecting tube (5), the motor (3) is started again, rice in the storage barrel (1) sequentially enters the discharging tube (8) and the gas collecting tube (5) under the pushing action of the material pushing plate (24), the auger (10, the rice taking action is realized, after the rice is taken, the threaded rod (20) is rotated, the partition plate (17) moves to the left side and resets, the left end of the gas collecting cylinder (5) can be gradually closed again by the cylinder cover (15), and finally the motor (3) is closed.
