Stone crushing device for mining machinery

Abstract

The invention discloses a stone crushing device for mining machinery. The device structurally comprises a dust inhibiting mechanism, a stone crushing case, a case cover, a feeding hopper, a power coupler, a base and a discharging hopper, wherein a housing of the dust inhibiting mechanism is fixed to the top part of an annular edge of the middle part of the stone crushing case through a bolt; the top part of the case is movably connected to the case cover and is in interference fit with the bottom part of the feeding hopper; the power coupler is vertically fixedly welded to the front end of thestone crushing case; the bottom part of the stone crushing case clings to the top part of the base; and the discharging hopper is mounted on the top part of the stone crushing case and communicates with the inner part of the feeding hopper at the left side. According to the stone crushing device for the mining machinery, the improved stone crushing device is capable of removing dust, and the operating environment of workers in work can be improved; and the service life is prolonged while the dust is decreased.

Description

technical field [0001] The invention relates to a crushing device for mining machinery, which belongs to the field of crushing devices. Background technique [0002] Mines include coal mines, metal mines, non-metal mines, building materials mines and chemical mines, etc. The scale of mines (also called production capacity) is usually expressed by annual output or daily output. , Divided into three types: large, medium, and small. The size of the mine should be compatible with the economically reasonable service life of the mine. Only in this way can infrastructure costs be saved and costs reduced. In the mine production process, the mining operation not only consumes the most manpower, material resources, occupies the most funds, but also has the greatest potential to reduce mining costs. Workers have been exposed to stone powder for a long time in the working environment and inhaled into the lungs to form silicosis, which is a very serious occupational disease. Contents ...
