A self-cleaning sieve plate and sieving mechanism

Abstract

The invention discloses a self-cleaning sieve plate and a material sieving mechanism, which are applied to material sieving and classifying equipment. The sieve plate comprises the material sieving mechanism, wherein the material sieving mechanism comprises sieve pieces, a frame and knocking and striking mechanisms, and a plurality of filtering holes are formed in the sieve pieces; the sieve pieces are fixed on the frame; the knocking and striking mechanisms are fixed on the frame, so that the sieve pieces are knocked and stricken by the knocking and striking mechanisms along with a vibration and discharging process of the material sieving mechanism. The self-cleaning sieve plate and the material sieving mechanism which are disclosed by the invention can solve the problem that rod strips are extremely easy to wear and crack when a rod strip type sieve plate is adopted in the prior art, and overcome the technological defect that material clamping and large material leakage are easy to cause in a long-term use process because the width of a reserved discharging gap between the adjacent rod strips is too wide or the length of the reserved discharging gap is too long.

Description

technical field [0001] The invention belongs to the technical field of material screening and classification, in particular to a self-cleaning sieve plate and a sieving mechanism. Background technique [0002] Most of the screening equipment is a vibrating screen, and the sieve plate is an important core component of the vibrating screen. When the vibrating screen vibrates, the material passes through the sieve plate, and the materials with different particle sizes are separated and classified under the vibration force applied by the external equipment. However, Sufficient separation has not been achieved in the prior art. [0003] At present, in each screening process, the selected sieve plate is a bar-type sieve plate, that is, several bars are distributed in strips to form a sieve plate structure, and the transverse gap reserved between adjacent bars is Feed gap. [0004] However, the rod-type sieve plate is currently commonly used as a sieve plate. In the actual applic...

Problems solved by technology

[0005] The invention provides a self-cleaning sieve plate and a sieve material mechanism, which solves the problem that when the bar-type sieve plate is used in the prior art, the bars are easily worn and broken, and due to the gap between the adjacent bars The width of the material gap is too wide, or the length is too long, which makes it easy to cause technical defects of large material leakage during long-term use
