A miniature jaw crusher with monitoring

Abstract

The invention discloses a miniature jaw crusher. The miniature jaw crusher comprises a miniature jaw crusher body and a monitoring system, wherein the miniature jaw crusher body comprises a machine body (3), a flywheel (11) and a belt pulley (15); the flywheel (11) and the belt pulley (15) are assembled with a camshaft (14) of the machine body (3) in a normally and reversely threaded manner; the monitoring system comprises a strain sensor (6) arranged on a bearing block (2) of the machine body (3); and the strain sensor (6) is connected with a signal processor (8) through a signal line (7), carries out processing and controlling through a computer (9). By the miniature jaw crusher, the problem that threaded assembly of the jaw crusher is locked automatically and continuously and is not easy to detach can be solved effectively, the jaw crusher can be detached conveniently, meanwhile, impact load in a crushing operation process can be monitored indirectly, particularly, the miniature jaw crusher can be detached conveniently after components of the miniature jaw crusher are locked in a threaded manner, and working condition maintenance of the miniature jaw crusher can also be implemented.

Description

Technical field [0001] The invention relates to a crusher, belonging to the technical field of ore crushing and powder milling, in particular to a miniature jaw crusher with monitoring. Background technique [0002] Jaw crushers are generally used as the primary crushing of ore crushing and powder milling. Since the jaw crusher uses camshaft-driven pressure plates to work in a manner similar to crushing, the ore is subjected to jaw crushing and general equipment processing The quantity is very large, the power consumption per unit product is very low, but the impact load of the equipment is very large, so the strength of the machine structure is very high, so when you see ordinary jaw crushers, it feels like they are heavy machinery with miniature jaws. Type crusher is not common, but in the laboratory, it is necessary to frequently crush ore to carry out research work. Therefore, the design meets the small amount of material processing needs in the laboratory, and is convenient ...

AI Technical Summary

Problems solved by technology

The structure of ordinary jaw crushers is generally that one end of the camshaft is a pulley and the other end is a flywheel. The flywheel and the pulley are very heavy, which is conducive to rotation to obtain a large moment of inertia to generate impact for crushing; because jaw crushers are generally long Time continuous impact load operation, so the bearing is easy to be damaged. To replace the bearing, the flywheel and pulley at both ends of the camshaft must be disassembled first. Carry out load-bearing transmission, so it needs to meet the needs of the laboratory and can be easily disassembled, assembled, and computer monitoring needs to be newly designed
