The guide plate 114 covers the upper end of the connecting shaft 121, so as to protect the connecting shaft 121 from damage. The arc screen plate 104 is fixedly installed with arc protection strips 124 on both sides close to the arc rack 123. The arc protection strips 124 can protect the gear 122 and prevent stones from falling on the gear 1 22 causes damage to it. When the servo motor 106 rotates, the belt 108 is driven to rotate through the pulley 107. The other end of the belt 108 is movably sleeved on the outer surface of the pulley 2 109. Therefore, the servo motor 106 drives the connecting shaft 121 to rotate while also driving the connecting shaft 2 115 to rotate. A plurality of eccentric blocks 116 are fixedly installed on the outer surface of the connecting shaft 2 115. The rotation of the eccentric blocks 116 drives the screen plate 117 to move up and down on the outer surface of the slide bar 119. Vibrating springs 120 are fixedly connected to the four corners of the bottom of the screen plate 117. The vibration springs 120 drive the screen plate 117 to perform secondary screening on the upper end of the stone.
