Description

Technical Field

[0001] This utility model relates to the field of stone processing, and in particular to a crushing device for stone production. Background Technology

[0002] Stone is a blocky or granular rock material formed by geological processes or artificial processing, possessing specific physicochemical properties and engineering application value. Stone is a fundamental material for engineering construction, with applications spanning multiple fields: in the construction field, it is used as a structural material and concrete aggregate; in the transportation field, it is used as road base layers and railway ballast; in the water conservancy field, it is used for dam construction and slope protection; and in the decorative field, it is used as shaped stone and artificial stone.

[0003] Stone production involves raw material mining, crushing, shaping, screening, and other auxiliary processes. Crushing requires the use of crushing equipment. In the Chinese utility model patent "Announcement No.: CN207102693U, Name: Stone Crusher", multiple screening plates are set up, and the size of the screen holes of the screening plates is adjusted according to the combination of different screening plates to screen stones of different particle sizes. Although the above application can screen stones, the screened stones are difficult to discharge and accumulate on the screen, which can easily affect the subsequent screening operation of the screen. In addition, in the above application and the prior art, the stones are piled up together and directly fed into the crushing roller, resulting in a large amount of stones being crushed by the crushing roller at one time, which affects the crushing accuracy of the crushing roller.
