AI Technical Summary

Technical Problem

The traditional pin-plate connection structure of crushers makes the replacement of hammer plates cumbersome and poses safety hazards. Furthermore, repeated disassembly and assembly leads to increased clearance, which in turn increases operational impact and vibration.

Method used

It adopts a segmented side shaft, docking shaft and positioning sleeve structure. The positioning sleeve connects multiple plate pins, allowing for individual replacement of the plate hammer. The side clamping plate and fastening screws ensure connection tightness and central support.

Benefits of technology

It enables quick assembly and disassembly of individual hammer plates, reducing safety hazards and wear, improving replacement efficiency and connection reliability, and reducing impact and vibration during operation.

Abstract

The utility model belongs to the technical field of plate hammer breaker, specifically relates to a breaker plate pin connecting and fixing structure, including two edge axle spare, a plurality of butt -joint axle spare and a plurality of positioning sleeve, the positioning sleeve sets up between edge axle spare and butt -joint axle spare, or set up between two butt -joint axle spare, all be provided with rotating sleeve on edge axle spare and butt -joint axle spare, the opposite side of two edge axle spare all is provided with edge clamping plate. The utility model discloses through setting up edge axle spare, butt -joint axle spare and positioning sleeve, can divide the plate pin of original whole root for plate hammer and rotor fixation into multiple sections, and the multiple sections are connected through positioning sleeve. Such through the sleeve joint of need replacing plate hammer is cancelled, can take out the plate hammer of need replacing, reinsert butt -joint axle spare and carry out the threaded connection with corresponding positioning sleeve, so can the single plate hammer is operated separately, thereby improve the replacement efficiency, reduce the security risk in the process of dismounting and the phenomenon of cooperation gap increase.
