When the piston 51 is located at the left end of the cylinder 50, the first contact block 70 presses the first automatic valve switch 71, the first automatic valve 12 is opened, the second contact block 72 does not press the second automatic valve switch 73, the second automatic valve 23 is in a closed state, and the blocking plate 24 blocks the trash box 20, so that a closed space is formed in the trash box 20. Piston 51 moves rightwards, negative pressure is generated in cylinder 50, cylinder 50 sucks air, cylinder 50 sucks water vapor in drying box 30 through hose 36, first automatic valve 12 is opened simultaneously, grains fall onto conveyor belt 60 in impurity removing box 20 through first automatic valve 12 and draft tube 13, in the grain falling process, dust in the grains is sucked into cylinder 50, grains and stones fall into impurity removing box 20, the grains are suspended above conveyor belt 60 just through airflow, stones are left on conveyor belt 60, piston rod 52 drives conveyor belt 60 and hose 36 to move rightwards, grains fall into lower hopper 21 under self gravity, stones are left on conveyor belt 60 and are conveyed to the right end of conveyor belt 60, and finally fall into chute 22 and are automatically discharged, so that automatic separation of the grains, the dust and the stones is realized. When the piston 51 moves to the rightmost end, the second automatic valve 23 is opened, and the grains in the lower hopper 21 enter the drying box 30 for drying.
During the leftward movement of the piston 51, the cylinder 50 is exhausted, and both the first automatic valve 12 and the second automatic valve 23 are closed.
The specific implementation process is as follows:
in the initial state, the piston 51 is located at the leftmost end, the first automatic valve 12, the second automatic valve 23 and the third automatic valve 33 are all in the closed state, and the impurity removing box 20 is blocked by the blocking plate 24. The hot-blast stove 43 is opened to introduce hot air into the drying box 30, and the bucket elevator 34 is started to feed the grains into the feed hopper 11. The first motor 40, the second motor and the third motor are started, the piston 51 moves rightwards, the cylinder 50 sucks air, the cylinder 50 sucks water vapor in the drying box 30 through the hose 36, the first automatic valve 12 is opened, grains in the feed hopper 11 enter the impurity removing box 20, dust is sucked into the cylinder 50 in the grain falling process, meanwhile, the grains are suspended above the conveyor belt 60 through air flow, stones fall on the conveyor belt 60, the piston rod 52 moves rightwards to drive the conveyor belt 60 and the hose 36 to move rightwards, the grains fall into the discharging hopper 21 under the action of self gravity, the stones are conveyed to the rightmost end by the conveyor belt 60 and then fall into the chute 22 and are automatically discharged, the second automatic valve 23 is opened when the piston 52 moves to the leftmost end, and the grains automatically fall into the drying box 30. During the leftward movement of the piston 51, both the first automatic valve 12 and the second automatic valve 23 are closed, the cylinder 50 is exhausted, the dust is filtered in the cylinder 50 and discharged to the dust collecting chamber 57 and finally settled in the cloth bag 59, and the clean air is exhausted into the air. On grain gets into the spiral sieve 42 in the stoving case 30, along with the rotation of spiral sieve 42, the grain is dried when rolling downwards, and finally grain arranges to out in the hopper 31, if grain is dried qualified, can open third automatic valve 33 and discharge grain, if grain is dried unqualifiedly, can close third automatic valve 33, let grain get into in the bucket carries 34, dry once more, until qualified.
The steps are repeated continuously, so that automatic intermittent impurity removal and automatic continuous drying of the grains are realized.
