Screen self-cleaning device

Abstract

The invention discloses a screen self-cleaning device which comprises a screen body and a screen arranged in the screen body, wherein a cleaning device is arranged at the lower part of the screen and comprises connecting bases, connecting rods and beating rings; the connecting bases are symmetrically arranged on the two sides of the bottom of the screen; the connecting rods are arranged between the connecting bases; through holes are formed in the centers of the beating rings; and the connecting rods are movably sleeved with the beating ring through the through holes. According to the screen self-cleaning device, the beating rings are mounted on the connecting rods to beat the screen; the beating rings can beat an elastic screen surface in all directions and at variable magnitudes; the device can effectively solve the problems of difficult screening and high possibility of hole blocking due to high viscosity and humidity of a material, so that the labor intensity of field workers is reduced; the production efficiency is improved; moreover, the connecting bases are movably connected with the screen and the connecting rods; the replacement is convenient; the replacement efficiency is improved; and the production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of vibrating screens, in particular to a screen self-cleaning device. Background technique [0002] Most of the existing vibrating screens have a ball frame structure inside, a basket is installed on the rail seat, and rapping balls are placed inside the basket. The basket material needs to be bent and welded when making the basket. The material thickness and material selection have limitations, and Baskets have a short service life and need to be replaced frequently. During replacement, all the sieve plates and rail seats need to be removed. The replacement workload is large and the replacement cost is high. When encountering materials with high viscosity and high humidity, the screening efficiency is low. , seriously affecting production efficiency and production costs. Contents of the invention [0003] The object of the present invention is to provide a screen mesh self-cleaning device with reasonable...
