Description

Broken conveyor of coal Technical Field The utility model belongs to the technical field of coal production equipment, and particularly relates to a coal crushing and conveying device. Background Coal is a solid combustible mineral which is buried underground by ancient plants and gradually undergoes complex biochemical and physicochemical changes, and in the process of processing and utilizing the coal, massive coal is often required to be crushed and then conveyed to subsequent procedures. However, the existing coal crushing and conveying device is single in crushing mode, cannot crush coal blocks of different sizes efficiently, is inconsistent in size after crushing, is easy to cause coal to be scattered during transportation, causes resource waste, and meanwhile, a large amount of dust is generated in the crushing process, so that the operators are not only endangered, but also certain potential safety hazards exist. Disclosure of utility model Aiming at the situation, in order to overcome the defects of the prior art, the coal crushing and conveying device provided by the utility model effectively solves the problems that the coal crushing and conveying device is single in crushing mode, cannot crush coal blocks with different sizes efficiently, is inconsistent in size after crushing, is easy to cause coal to be scattered during transportation, causes resource waste, and generates a large amount of dust in the crushing process, so that the health of operators is endangered, and a certain potential safety hazard exists. The technical scheme adopted by the utility model is as follows: the utility model provides a coal crushing and conveying device, which comprises an equipment frame, a crushing and conveying structure and a dust removing structure, wherein the crushing and conveying structure is arranged on the equipment frame; The crushing unit comprises a jaw crusher, a charging hopper, a toothed roller crusher and a hammer crusher, wherein the jaw crusher is fixedly arranged on a top plate above the equipment frame, the charging hopper is fixedly arranged above the jaw crusher, the toothed roller crusher is fixedly arranged on a square diaphragm in the equipment frame, a feeding hole is positioned below a discharging hole of the jaw crusher, and the hammer crusher is fixedly arranged on a diaphragm below the equipment frame, and the feeding hole is positioned below the discharging hole of the toothed roller crusher.
