Efficient stone crusher for mines

Abstract

The invention discloses an efficient stone crusher for mines. The efficient stone crusher comprises a precrushing box, a crushing box, a collecting box, a feeding motor, a feed hopper and a feeding cylinder; the top of the precrushing box communicates with the upper end of the feeding cylinder inclined downwards; an output shaft of the feeding motor is fixedly connected with a spiral auger; a horizontal precrushing roller is mounted in an unloading port; multiple crushing teeth, longitudinally arranged, are fixed on the side wall of the unloading port; two horizontal main crushing rollers, cooperating with each other, are arranged in the crushing cavity; and a baffle plate is arranged in the collecting box under a blanking port. Stones crushed by the main crushing rollers can be contactedwith the main crushing rollers by multiple times from the bottoms, so that the crushing of the stones is facilitated; the crushed stones fall down from gaps at the two ends of the baffle plate, so that the stones fall smoothly, and are not easy to block; the stones in the blanking port can be totally discharged through manual operation to achieve the use flexibility; and during loading, through the feeding cylinder inclined upwards, more time and power are saved in feeding, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a high-efficiency crushing stone crusher for mines. Background technique [0002] Mining stone crushers are mainly used for crushing various types of stones. In practice, double-roller crushers are widely used. Double-roller crushers use two rollers to crush materials that need to be crushed. The effect is better; but when there are more stones, it is easy to cause the load of the crushing roller to increase, so that the crushing roller stops, causing the motor to burn out, and affecting the use of the stone crusher; the stone needs to be manually fed into the higher equipment when loading. The required labor intensity is high and consumes a lot of manpower, which is very unfavorable to the production of mines; in addition, two crushing rollers are used for extrusion, and often only one extrusion is used, resulting in incomplete crushing of some stones, and frequent manual operations are re...

The required labor intensity is high and consumes a lot of manpower, which is very unfavorable to the production of mines; in addition, two crushing rollers are used for extrusion, and often only one extrusion is used, resulting in incomplete crushing of some stones, and frequent manual operations are required to circulate the stones. Pour it into the stone crusher to increase the labor intensity of workers
