Dust suppression and material blocking prevention jaw crusher

Abstract

The invention discloses a dust suppression and material blocking prevention jaw crusher whcih comprises a machine body. A working cavity with an upper opening and a lower opening is formed in the machine body, an adjusting device is fixedly connected to the right side wall of the working cavity, a power device is fixedly arranged on the upper side face of the machine body, and a crushing plate is arranged at the output end of the power device; and the crushing plate extends into the working cavity, the right side face of the lower end of the crushing plate is hinged to the left end of the adjusting device, and a dust suppression device used for absorbing dust is arranged at the lower end of the crushing plate. Through the arrangement of a telescopic air pipe and an abutting rod, when a first overturning plate performs crushing, the telescopic air pipe is continuously extruded, so that the telescopic air pipe continuously exhausts air from a mounting groove through a second one-way valve, at the moment, due to pressure, dust and air enter the telescopic air pipe through a dust inlet hole and the second one-way valve, and the purpose of dust suppression is achieved.

Description

technical field [0001] The invention belongs to the field of mining equipment, in particular to a dust-suppressing and jam-proof jaw crusher. Background technique [0002] The jaw crusher is the most commonly used crushing equipment in the mining industry. It is mainly used for coarse crushing. However, in normal work, there will be situations where the crusher does not produce material. During the working process of the jaw crusher, the ore material with high water content enters the crushing chamber, and the crusher breaks the water-containing material into small pieces. The small pieces of material have a certain viscosity and will stick to each other. together, and blocked between the two jaw plates in the crushing cavity, resulting in the phenomenon of material jamming; it may also be that the crushed material is mixed with relatively viscous rare earth, so that the material is stuck into a piece and blocked in the crushing cavity , material jamming occurs; and dust wi...

[0002] The jaw crusher is the most commonly used crushing equipment in the mining industry. It is mainly used for coarse crushing. However, in normal work, there will be situations where the crusher does not produce material. During the working process of the jaw crusher, the ore material with high water content enters the crushing chamber, and the crusher breaks the water-containing material into small pieces. The small pieces of material have a certain viscosity and will stick to each other. together, and blocked between the two jaw plates in the crushing cavity, resulting in the phenomenon of material jamming; it may also be that the crushed material is mixed with relatively viscous rare earth, so that the material is stuck into a piece and blocked in the crushing cavity , material jamming occurs; and dust will be generated when the jaw crusher is working, which will affect the health of the staff. Therefore, it is urgent to design a jaw crusher that can suppress dust and effectively solve the problem of material jamming
