Mini Jaw Crusher

Abstract

The invention discloses a micro jaw crusher which comprises a crusher body (3), a flywheel (11) and a belt pulley (15), wherein the flywheel (11) and the belt pulley (15) are in positive screw assembling and negative screw assembling with a camshaft (14) of the crusher body (3) respectively; a copper-plastic composite cushion (12) is arranged between the flywheel (11) and the camshaft (14), and comprises a copper cushion (21) and fusible plastic washers (22) arranged at the two sides of the copper cushion (21); a hoop assembly (16) is arranged between the belt pulley (15) and the camshaft (14), and comprises a plurality of hoop bodies (31), hoop cushions (33) in fit assembling with the hoop bodies (31), and connecting pieces for fixing the hoop bodies (31); the cross sections of the hoop bodies (31) are wedge-shaped; and the hoop bodies (31) are in fit assembling with wedge-shaped clamping grooves of the hoop cushions (33). According to the micro jaw crusher, the problem that the disassembling is difficult due to the fact that continuous automatic locking occurs under loading action by adopting the screw assembling of the conventional jaw crusher can be solved effectively, and convenient and quick disassembling can be realized.

Description

technical field [0001] The invention relates to a crusher, which belongs to the technical field of ore crushing and powder making, and in particular relates to a miniature jaw crusher. Background technique [0002] Jaw crushers are generally used as primary crushing for ore crushing and powder making. Because the jaw crusher uses a camshaft-driven press plate to work in a crushing manner similar to crushing, it performs jaw crushing on ores. General equipment processing The quantity is large, and 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 seeing ordinary jaw crushers, people feel that they are all heavy machinery, and the miniature jaw Type crushers are not common, but in the laboratory it is often necessary to crush ore to carry out research work, so the design can meet the needs of a small amount of material handling in the laboratory, and it is easy to ma...

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 bulky, 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 laboratory use and can be easily and quickly disassembled, and a new design is required for assembly
