Three-shaft vibrating screen with buffering storage hopper

Abstract

The invention relates to a three-shaft vibrating screen with a buffering storage hopper. The three-shaft vibrating screen comprises a screen frame, a supporting base, spring sets, a balance weight box and balance weight mechanisms arranged in the balance weight box. Three balance weight mechanisms are arranged in the balance weight box, and each balance weight mechanism comprises a wallboard base, wherein a bearing is arranged on the outer side wall of the wallboard base and sleeved with a bearing box, a transmission shaft is inserted in the hollow part in the middle of the wallboard base, the bearing box and the transmission shaft are connected through an end cover to conduct transmission, a balance weight block is arranged on the bearing box, balance weight pins are arranged between the balance weight block and the bearing box, the outmost circle of the bearing box is sleeved with a gear ring, and the balance weight box is fixed to the side wall of the screen frame. The spring sets are fixed between the supporting base and the screen frame, a screen shoe is arranged in the screen frame, the screen shoe is coated, or sleeved or clamped with buffering strips, and a discharging base is arranged on the right edge of the screen frame and is connected with the storage hopper. The three-shaft vibrating screen at least has the advantages that the gravity center and weight of the balance weight whole can be adjusted, materials can be screened conveniently, and the screen shoe is resistant to abrasion and long in service life.
