Ore crusher

Abstract

The invention relates to the technical field of ore crushing, and discloses an ore crusher. The ore crusher comprises a bottom plate, guide columns are arranged on the side, away from the ground, of the bottom plate, a lifting plate is slidably connected to the sides, away from the bottom plate, of the guide columns, and the ore crusher further comprises a lifting mechanism and a crushing mechanism; the lifting mechanism is arranged on the two sides of the bottom plate and comprises an air cylinder used for pushing the lifting plate to move; and the crushing mechanism comprises supporting plates arranged on the side, away from the bottom plate, of the lifting plate, the supporting plates are fixedly connected with the two sides of the lifting plate, the ends, away from the lifting plate, of the supporting plates are rotationally connected with rotating shafts, cams are arranged at the ends, away from the device center, of the rotating shafts, rotating discs are arranged at the ends, close to the device center, of the rotating shafts, and a fixing rod is arranged between the two rotating discs. According to the ore crusher, two components, an impact head and a screen frame, can be driven to move at the same time through a driving motor, the impact head can carry out crushing treatment on ore, and screening treatment of ore can be achieved through up-down movement of the screen frame.

Description

technical field [0001] The invention relates to the technical field of ore crushing, in particular to an ore crusher. Background technique [0002] The ore crusher is mainly used for crushing the stones produced during mining, often using extrusion, splitting, bending, impact, rolling and other methods to break large rocks into pieces. Commonly used are jaw crusher, cone crusher, hammer crusher and roller crusher. [0003] However, the current common crushers can only simply crush the stones, but the crushed stones cannot be effectively screened, which leads to some stones not being crushed well and then together with other crushed stones. Discharge, resulting in uneven crushing effect, so this situation needs to be improved. Contents of the invention [0004] The present invention provides an ore crusher, which solves the problems raised in the above-mentioned background technology. [0005] To achieve the above object, the present invention provides the following tech...
