Description

Technical Field

[0001] The utility model belongs to the technical field of crushers, and in particular relates to a crusher screen installation structure. Background Art

[0002] The crusher is a waste treatment equipment used to crush domestic waste, power plant waste, construction waste and hazardous waste. During the material crushing process, in order to prevent large particles of material from not being crushed properly, a screen is installed around the crusher rotor. Only when the material particle size is smaller than the mesh diameter of the screen can it pass through, thereby avoiding blockage in the subsequent pipeline transportation process.

[0003] For example, Chinese patent publication number CN207271415U discloses an automatically locking and detachable screen for a crusher, which is evenly arranged on one side of the cover plate through a screen support plate; a screen sheet is provided between adjacent screen support plates, and guard plates are provided at both ends of the screen sheet, and mounting holes are provided on the guard plates; the screen sheet is screwed to the screen support plate through the mounting holes; the guard plate and the screen support plate are connected by bolts, and after the screen sheet is worn, the screen sheet can be easily removed and replaced, thereby improving work efficiency.

[0004] Although this patent provides a crusher installation structure that is convenient for replacing the screen, this patent has structural deficiencies. For example, the purpose of convenient installation and disassembly is achieved by providing a guard plate, a screen support plate and an automatic locking device provided on the cover plate through the screen. In actual use, because the crusher's rotating shaft is almost coaxial with the screen and the distance between the crusher's rotating shaft and the screen is very close, the cover plate drives the screen support plate and the screen plate to rotate through the rotation of the rotating shaft, so that the screen plate is away from the crusher's rotating shaft, but it needs to be rotated at a larger angle, and then the screen plate is disassembled and replaced, which makes the operation process too complicated. At the same time, the screen plate is limited and fixed by the threaded connection between the mounting hole opened by the guard plate provided on the screen plate and the support plate, which makes the disassembly and assembly of the screen plate not flexible enough.
