AI Technical Summary

Technical Problem

The mechanical protective cover of existing underground crushers is subject to wear or thinning of the rigid liner plate due to the direct impact of high-speed splashing material, which affects the safety and service life of the liner plate.

Method used

The system employs a chain structure consisting of a head buffer roller, a middle buffer roller, and a tail buffer roller. Combined with a lead screw slide rail and a sliding frame driven by a servo motor, it removes embedded gravel through a hydraulic push rod, achieving both buffering and slag removal functions and extending the service life of the protective cover.

Benefits of technology

The protective cover has improved its protective efficiency, extended its service life, reduced wear, and ensured operational safety and production efficiency.

Abstract

The present application relates to the technical fields of downhole protection, in particular to a downhole crusher anti-splashing mechanical protective cover, which comprises a crusher assembly, a moving assembly connected to the crusher assembly, a buffer assembly movably connected to the moving assembly, a support assembly connected to the crusher assembly, and a slag removal assembly movably connected to the support assembly, wherein the buffer assembly comprises a head buffer roller movably connected to the moving assembly, a plurality of middle buffer rollers arranged inside the crusher assembly, and a tail buffer roller. The present application comprises a chain structure composed of the head buffer roller, the middle buffer rollers, and the tail buffer roller to form a circular arc-shaped protective structure. When splashing stones occur, the stones will hit the middle buffer rollers, and the stones will exert a force on the middle buffer rollers to drive them to rotate, thereby buffering the impact force exerted by the stones through the rotation of the middle buffer rollers, and thus improving the protection efficiency of the entire protective cover to a certain extent.
