[0027] During the implementation of the utility model: after the hawthorn and water enter the screening box through the feed port 9 and the water inlet 12 respectively, the output shaft of the driving member 8 rotates forward, the first ratchet 72 cooperates with the first one-way pawl, that is, the rotating rod drives the rotating shaft 7 to rotate, and then the rotating shaft 7 drives the semicircular wheel 71 to rotate, and the semicircular wheel 71 regularly cooperates with the screening box to push the screening box to compress the second elastic member 5. When the semicircular wheel 71 does not cooperate with the screening box, the second elastic member 5 pushes the screening box to reset, thereby causing the screening box to vibrate laterally, and the second ratchet 111 and the second one-way pawl do not cooperate, that is, the first push plate 14 and the second push plate 15 will not move, so as to avoid the hawthorn from being discharged in advance. When the hawthorn enters the screening box through the feed port 9, the pressure on the primary screening plate 4 and the secondary screening plate 3 increases, thereby driving The auxiliary rod 42 compresses the first elastic member 43. When the debris in the hawthorn is discharged through the sewage outlet 2, the pressure on the primary screening plate 4 and the secondary screening plate 3 is reduced, and then the first elastic member 43 drives the auxiliary rod 42 to rise, further completing the vertical vibration and increasing the screening efficiency. After the hawthorn is cleaned and screened, the output shaft of the driving member 8 is reversed, the second ratchet 111 and the second one-way pawl cooperate, and the rotating shaft 10 drives the reciprocating rod 11 to rotate, and the reciprocating rod 11 drives the reciprocating block 13 to reciprocate, and then the reciprocating block 13 drives the first push plate 14 and the second push plate 15 to move through the connecting rod, and the hawthorn on the primary screening plate 4 and the secondary screening plate 3 are pushed into the primary collecting box 41 and the secondary collecting box 31 respectively.
