Description

Technical Field

[0001] This utility model relates to the field of hammer crusher technology, and in particular to a hammer crushing device for a hammer crusher. Background Technology

[0002] In the dismantling of used refrigerators, hammer crushers are an important type of crushing equipment. Their main function is to break down used refrigerators into smaller particles for subsequent processing and utilization. During the operation of a hammer crusher, the hammers, as the key working components, are responsible for directly crushing the materials. The performance and durability of the hammers directly affect the working efficiency and production costs of the hammer crusher.

[0003] Traditional hammerhead devices typically employ a fixed connection, with the hammerhead and hammer shaft integrally molded. While this design ensures the stability and strength of the hammerhead to some extent, it also presents several problems in practical use. First, the hammerhead is subjected to severe impacts and wear during prolonged operation, leading to deformation and shortening its lifespan, requiring periodic replacement. Second, traditional hammerheads are directly connected to the crusher's shaft, making disassembly inconvenient, the replacement process cumbersome, and time-consuming, increasing equipment downtime and reducing production efficiency. Furthermore, the disassembly and replacement of hammerheads may damage other components, increasing maintenance costs.

[0004] There are no effective solutions yet for the problems in related technologies, such as the cumbersome disassembly of hammers from hammer crushers, the easy deformation of hammers affecting service life and work efficiency, and the easy damage to equipment caused by frequent disassembly of other equipment.
