Dustproof adjustable coal crushing and screening equipment

Abstract

The invention discloses dustproof adjustable coal crushing and screening equipment. The dustproof adjustable coal crushing and screening equipment comprises a machine body, a feeding opening with an upward opening is formed in the upper side of the machine body, closed door positioning cavities communicating with each other are symmetrically formed in the left side wall face and the right side wall face of the feeding opening, and closed door shafts are fixedly arranged between the front wall faces and the rear wall faces of the closed door positioning cavities; turnover sealing doors are hinged to the outer circle faces of the sealing door shafts, and an extrusion cavity is formed in the lower side of the feeding opening in a communicating mode. According to the dustproof adjustable coalcrushing and screening equipment, large coal blocks are cut, coal dust in the cutting process is collected and treated, dry-wet separation is achieved, large coals and small coals are classified in time while the coal cutting quality is effectively guaranteed, pollution of the coal dust to the environment is avoided, in addition, the coal cutting size can be adjusted by adjusting the coal extrusion gap, pressure is unloaded in time through the machine body, and the service life of a hydraulic cylinder is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of mineral resource processing, in particular to dust-proof adjustable coal crushing and screening equipment. Background technique [0002] In our daily life, a large amount of coal is used. Coal needs to undergo a series of processing in the early stage of use. For processed dry coal, it is easy to generate a large amount of coal dust, which not only pollutes the environment, but also affects people's health. In the existing Among the coal processing equipment, there are few equipment with coal dust removal function, which cannot effectively reduce the pollution of coal dust to the environment. In the process of processing, it is also extremely important to deal with the size of coal cutting blocks. Manual sorting is inefficient and reduces the coal processing process. The present invention illustrates a device capable of solving the above-mentioned problems. Contents of the invention [0003] technical...
