Vibrating screen

Abstract

The invention discloses a vibrating screen. The vibrating screen comprises an upper screen beam, a lower screen beam, a screen and a screen pressing mechanism, wherein the screen pressing mechanism comprises an upper connecting plate, a lower connecting plate, a right-hand Y joint, a left-hand Y joint and a right-hand and left-hand screw, and the upper connecting plate is vertically fixed below the upper screen beam; one end of the right-hand Y joint is vertically hinged to the upper connecting plate, and the other end is in threaded connection with the upper end of the right-hand and left-hand screw; one end of the left-hand Y joint is in threaded connection with the lower end of the left-hand and right-hand screw, and the other end of the left-hand Y joint is vertically hinged to the lower connecting plate; a pressing rod is fixed at the bottom of the lower connecting plate; when the end of the pressing rod abuts against a limiting block at the position of a discharging port of the vibrating screen, the right-hand and left-hand screw tends to be perpendicular to the screen; and a lower jacking block is fixed to the top of the lower screen beam, the screen is placed on the lower jacking block, and the lower jacking block and the pressing rod are used for pressing the screen up and down. In the use process of the vibrating screen, the screen pressing mechanism has a self-fastening effect on the screen, the right-hand and left-hand screw is pulled outwards to incline during disassembly, so that the screen is loosened and is convenient to disassemble, and time is saved and convenience is achieved.

Description

technical field [0001] The invention belongs to the technical field of material screening, in particular to a vibrating screen. Background technique [0002] Most of the vibrating screens in the prior art are fixedly connected to the screen box through densely arranged fastening bolts. When replacing the screen, it is necessary to manually enter the inside of the screen box to loosen the bolts for replacement. It costs more to replace the screen each time. For a long time, work efficiency is low. In addition, during production, in order to make it easier for maintenance personnel to enter and exit to replace the screen mesh, a sufficient height needs to be left between each layer in the screen box, which wastes space and materials. Contents of the invention [0003] The invention provides a vibrating screen mesh pressing device, which can quickly disassemble the screen mesh without manually entering the screen box for operation. [0004] Technical scheme of the present i...
