Coal smashing device

Abstract

The invention discloses a coal smashing device which comprises a smashing bin, a motor, a coal guide hopper, a coal receiving hopper, a coal conveying pipe, a coal lifting hopper, an electromagnetic valve, a dust collecting pipe, a dust removing device, a fan and a gas outlet pipe. The motor and a feeding barrel are arranged on the top of the smashing bin, the smashing bin is sealed, and the motor is a bi-directional rotary motor; the motor is in drive connection with a spindle, a stirring paddle is arranged on the upper side of the spindle, and a movable cone is arranged below the stirring paddle; movable cutters are arranged on the outer surface of the movable cone, protrusions are arranged on the lower side of the smashing bin and are matched with the movable cone, and fixed cones are arranged on the surfaces of the protrusions; a bin is arranged below the movable cone and the fixed cones; the bin is connected with the coal guide hopper, the coal receiving hopper is connected with the bottom of the coal guide hopper and is connected with the coal lifting hopper by the coal conveying pipe, and the electromagnetic valve is arranged on the coal conveying pipe; the dust collecting pipe is arranged on the top of the coal receiving hopper and is connected with an air inlet of the dust removing device. The coal smashing device has the advantages that the coal smashing device is safe in use, good smashing effect and dust removing effects can be realized, and accordingly the physical health of staffs can be guaranteed.

Description

technical field [0001] The invention relates to a coal crushing device, in particular to a coal crushing device. Background technique [0002] Crusher can be divided into medical crusher and mining crusher according to major categories; [0003] Common crushing machines for heavy mining machinery include jaw crusher, impact crusher, vertical impact crusher, hydraulic cone crusher, ring hammer crusher, hammer crusher, roll crusher, compound crusher, Cone crushers, double-stage crushers, gyratory crushers, mobile crushers, etc., the working principles of different types of crushers are completely different; [0004] Cone crusher is a mining machine used to crush ore. When working, the ore enters from the feed port of the cone crusher, and is crushed by impact and extrusion in the crushing cavity formed by the movable cone and the fixed cone. However, during the feeding process, the ore is broken to produce debris, which is easy to splash People, and the feeding direction is...

AI Technical Summary

Problems solved by technology

When working, the ore enters from the feed port of the cone crusher, and is crushed by impact and extrusion in the crushing cavity formed by the movable cone and the fixed cone. However, during the feeding process, the ore is broken to produce debris, which is easy to splash people, and the feeding direction is easy to deviate, which makes the materials in the crushing chamber on both sides uneven and increases the load of the crusher.
