The connecting rod 11 pushes the ball seat 64 upward, and the ball seat 64 drives the right side of the screen 62 to move up and down. The motor 12 drives the eccentric wheel 13 to rotate, and then the eccentric wheel 13 drives the connecting rod 11 to move upward. The connecting rod 11 pushes the ball seat 64 upward, and the ball seat 64 drives the right side of the screen 62 to move up and down. The motor 12 drives the eccentric wheel 13 to rotate, and then the eccentric wheel 13 drives the connecting rod 11 to move up and down during rotation. The connecting rod 11 drives one end of the screen 62 to perform a reciprocating motion. When one end of the screen 62 moves up and down, the materials can quickly pass through the screen 62, accelerating the filtration speed of the screen 62. The spring 14 supports the vibrating plate 15. When the filtered materials fall onto the vibrating plate 15, they slide to the left, achieving the effect of conveying the materials.
