Description

Technical Field

[0001] The utility model relates to the technical field of solid waste disposal and crushing, in particular to a piston-type material pressing structure of a crusher. Background Art

[0002] During the operation of the crusher, due to the difference in the size of the materials entering the crusher, when large pieces of materials enter the crusher, there will be a bridging phenomenon (large pieces of materials will accumulate on the top of the cutter frame and cannot be crushed). The crusher cutter frame rotates normally but does not perform actual crushing work, resulting in no load.

[0003] Since the crushing volume is low when the crusher is under load or no load, but the energy consumption is the same as that when fully loaded, the traditional crusher needs to be manually pressed with a wooden stick in the crusher when it is under load or under load. However, manual pressing takes time to react and process, resulting in low crushing efficiency, high energy consumption cost, and high labor cost. In addition, the traditional crusher relies on manual pressing, so it is necessary to hire one person to be responsible for pressing the material, which has a high risk factor. The traditional crusher uses a wooden stick to press the material in the crusher, which has high requirements for workers. If the force is small, it cannot be pressed down, and if the force is large, the wooden stick is easily brought into the crusher. After the wooden stick breaks under the force, it is easy to hit people or bring people into the crusher. Utility Model Content
