Movable screening and breaking integrated machine for underground coal mine road

Abstract

The invention provides a movable screening and breaking integrated machine for an underground coal mine road, and relates to the technical field of underground coal mine equipment. The movable screening and breaking integrated machine is arranged at the position of a reversed loader head and located on the upper portion of a conveying belt of a belt conveyor. The movable screening and breaking integrated machine comprises a road body, a screening device and a breaking device. The screening device and the breaking device are arranged in one device, coal briquettes entering the road body from the reversed loader head are screened by the screening device firstly, small coal briquettes penetrate through the screening device to fall onto the conveying belt of the belt conveyor, large coal briquettes slide to the position making contact with the breaking device along the screening device to be broken by the breaking device, sequential screening and breaking are achieved, the situation that the small coal briquettes are broken again is avoided, a part of distance is reserved at the screening position of the screening device, the screening time of the coal briquettes is prolonged, the coalbriquettes are conveniently screened, the large coal briquettes incapable of penetrating through the screening device make contact with the breaking device to be broken, screening and breaking are integrated, no procedures are added, and therefore the production efficiency is relatively improved.

Description

technical field [0001] The invention relates to the technical field of underground coal mine equipment, in particular to a mobile screening and crushing integrated machine for underground coal mines. Background technique [0002] Coal mines need to be crushed and then transported after mining. The current method is that the mined coal mines are first crushed by a crusher, and then unloaded to the conveyor belt by a reloader. The crushed coal in the crusher is of different sizes. Coal blocks can be broken into small coal blocks that meet the requirements, but if small coal blocks are crushed by a crusher, they will easily become low-quality cinders. Therefore, it is very difficult to screen the coal blocks first and then crush them. Minimize the situation that small coals are broken again. [0003] The current method of screening first and then crushing is to add a screening machine, and the screening machine and the crusher are operated separately. Although this method can ...

Problems solved by technology

[0003] The current method of screening first and then crushing is to add a screening machine, and the screening machine and the crusher are operated separately. Although this method can achieve the goal, but because of the increase in the process, the production efficiency will be reduced.
