Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinders, in particular to a combined release oil cylinder. Background Art

[0002] During operation, the existing ore crusher uses a group of active rollers and a group of auxiliary rollers to convert large pieces of stone into small gravel after passing through the crusher. During this crushing process, the auxiliary rollers need to frequently reciprocate to cooperate with the active rollers. Since the active rollers and the auxiliary rollers generate large vibrations during the reciprocating motion, the connection between the hydraulic cylinder and the accumulator is easily loosened or even disconnected, thereby damaging the hydraulic cylinder and the accumulator, thereby increasing maintenance costs. At the same time, the original release cylinder is a split structure when it leaves the factory. The quality inspector needs to inspect the split components, and after assembly on site, it also needs to undergo a secondary inspection of the entire structure, which is time-consuming and labor-intensive. Therefore, a combined release cylinder is proposed. Utility Model Content
