Sieve plate for multi-shaft shearing type crushing machine

Abstract

The invention provides a sieve plate for a multi-shaft shearing type crushing machine. The multi-shaft shearing type crushing machine comprises a main cutter head and an auxiliary cutter head. The sieve plate comprises a sieve plate body, supporting side plates and locking plates, wherein the supporting side plates are fixedly connected to the left side and the right side of the sieve plate body;each locking plate is fixedly connected to the corresponding supporting side plate, and is used for fixing the sieve plate to the multi-shaft shearing type crushing machine; the sieve plate body comprises a main sieve part; the main sieve part comprises one or more main reinforcement plates; each main reinforcement plate comprises a plurality of arc-shaped first bar gratings; the first bar gratings form a comb tooth shape; and the normal line of each first bar grating can face the center line of a main cutter head. The sieve plate disclosed by the invention has high impact resistance, is not sensitive to the material abrasion, has preferable crushing effects on strip fiber materials or flexible slender type materials including jumbo bags, dust cloth and cloth, has higher crushing efficiency, has higher blocking resistance, and is more suitable for crushing of complex materials.

Description

technical field [0001] The invention relates to a sieve plate of a crusher, in particular to a sieve plate used for a multi-shaft shearing crusher. Background technique [0002] In the fields of mining, chemical industry, solid waste, hazardous waste, etc., large-volume materials are generally crushed step by step through crushers. Common crushers include jaw crushers, roll crushers, hammer crushers, shear crushers, etc. The main reference factors to measure the quality of a crusher are the smoothness of the processed materials and the actual processing capacity of the crusher. Due to the complexity and diversity of material sources, the sieve plates of the existing shearing crushers are mostly perforated structures, which have poor impact resistance. The sieve plates are easily deformed by the impact of falling materials, making the materials easy to block the sieve holes, or Due to the unreasonable design, especially in the face of long strips or fibrous materials, they ...

AI Technical Summary

Problems solved by technology

Due to the complexity and diversity of material sources, the sieve plates of the existing shearing crushers are mostly perforated structures with poor impact resistance. The sieve plates are easily deformed by the impact of falling materials, making the materials easy to block the sieve holes, or Due to the unreasonable design, especially in the face of long strips or fibrous materials, they cannot fall into the holes of the sieve plate to the maximum extent, causing the materials to be repeatedly drawn into the crushing area by the cutter head for multiple crushing, thereby reducing the crushing efficiency, or causing the holes to be blocked. As a result, the material cannot fall, resulting in equipment shutdown; moreover, the unreasonable selection of the sieve plate causes the sieve plate to be corroded or worn too quickly, requiring frequent replacement of the sieve plate, and frequent shutdowns cause major maintenance troubles and economic losses
