A screening type reloading crusher

Abstract

The invention relates to the technical field of screening crushing equipment for underground coal mines and mines, in particular to a screening transshipment crusher. The provided screening transshipment crusher is compact in structure, safe, easy to achieve, controllable in crushed particle size and good in floor roadway adaptability. The screening transshipment crusher comprises a detachable rack, tooth rollers, tooth rings, a chain wheel assembly, a scraper chain, a crushing beam, a synchronous gear, a telescopic groove, a belt conveyor and a motor. The chain wheel assembly, the scraper chain and the telescopic groove are the original parts of an original transshipment machine. The tooth rollers, the crushing beam and the synchronous gear are fixed to the detachable rack. The detachable rack is connected with the original transshipment machine through a screw-nut structure. The tooth rings are detachably connected to the tooth rollers. The number of the tooth rollers is two. The two tooth rollers are connected through the synchronous gear and move oppositely. One of the tooth rollers is connected with the motor. The crushing beam is arranged below the middle of the two tooth rollers. The belt conveyor is arranged below the chain wheel assembly and the crushing beam. The screening transshipment crusher is mainly applied to the coal mines.

Description

Technical field [0001] The invention relates to the technical field of screening and crushing equipment underground and above the mine, and more specifically, to a screening type transfer crusher. Background technique [0002] Coal mining and transportation at fully mechanized working faces in underground coal mines mostly use reloading machines and scraper conveyors. Most of the coal and ore transported are the size of the original mined size. Usually due to actual requirements, it is necessary to remove the coal and ore. The discharging particle size reaches the required particle size, so it is necessary to increase the corresponding crushing equipment to control the particle size. The whole set of equipment requires a large space, and the dust and noise are also large. [0003] At present, it is commonly used in mines to crush a part of coal and ore during transportation by a transfer machine, and then transport it out of the mine through a belt conveyor, and then use subsequent...

Problems solved by technology

[0002] Most of the coal mining and transportation in the fully mechanized mining face of the coal mine use reloaders and scraper conveyors. Most of the coal and ore transported out are the size of the original mining. The output particle size reaches the required particle size, so it is necessary to add corresponding crushing equipment to control the particle size. The whole set of equipment requires a large space, and the dust and noise are also relatively large.

[0003] At present, it is generally used in mines to crush a part of coal and ore during the transportation process of the reloader, and then transport it out of the mine through the belt conveyor, and then use the subsequent crushing equipment for crushing to meet the requirements of the output particle size. Although this can also meet the actual final requirements, However, the transportation and crushing space required for the installation of equipment is large, the structural equipment is more complex, the maintenance is cumbersome, and the reliability is low.
