Mine crusher

Abstract

The invention discloses a mine crusher. The mine crusher comprises a crushing box, wherein the upper end of the crushing box is fixedly communicated with a feeding hopper; the inner wall, close to theupper end, of the crushing box is symmetrically provided with two rotating shafts; the shaft walls of the rotating shafts are fixedly sleeved with crushing tubes; the surfaces of the crushing tubes are uniformly and fixedly connected with a plurality of crushing protruded pricks; one of the rotating shafts is rotatably connected with the inner wall of the crushing box through a ball bearing and one end of one of the rotating shafts extends out of the crushing box through a through hole; the outer wall of the crushing box is fixedly provided with a motor; an output shaft of the motor is fixedly connected with one end, extending out of the crushing box, of the upper rotating shaft; the two ends of the other rotating shaft extend out of the crushing box through a strip-shaped opening which is formed in the surface of the crushing box in the horizontal direction and are rotatably connected with a positioning plate through the ball bearing; the inner wall of the upper end of the feeding hopper is connected with a material blocking plate through hinges. According to the mine crusher disclosed by the invention, a crushing space can be changed according to actual demands so as to obtain crushed stone materials with different sizes, and thus, the stone materials can be separated from limes better.

Description

technical field [0001] The invention relates to the technical field of crushers, in particular to a crusher for mines. Background technique [0002] At present, when mining, it is often necessary to use a stone crusher to crush the ore into smaller stones and transport them away. The existing stone crusher will produce a large amount of lime when crushing the stone, and a large amount of lime is mixed with the crushed stone. During the transportation, this kind of lime will generate a lot of dust, which will lead to poor air quality around the mine, and the crushing mechanism is fixed, and the crushing size of the stone cannot be adjusted according to people's actual needs. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the stone crusher in the prior art will produce a large amount of lime when crushing stones, and a large amount of lime will be mixed in the crushed stone and transported away, and this lime will produce...
