Intelligent coal and gangue sorting device based on continuous transportation of underground coal mine rubber belt

Abstract

The invention discloses an intelligent coal and gangue sorting device based on continuous transportation of an underground coal mine rubber belt. The device comprises a power device, a conveying device, a lifting device and a recognition and separation device, the power device comprises a connecting belt, a belt pulley and a carrier roller, and the carrier roller performs power transmission to drive the belt pulley and the connecting belt to rotate; the conveying device comprises a conveying belt and a gangue throwing box, and the gangue conveying belt is responsible for conveying coal and gangue; the lifting device comprises a guide rail, a crab claw separating device and a lifting belt and is responsible for separating and transporting blocky coal; the recognition and separation device comprises a material box, a sliding groove, a camera device, a weighing device, a controller and an information processing device, coal is divided through the material box, queuing is conducted through the sliding groove, recognition is conducted through the weighing device, and then a baffle is controlled to be opened and closed to fall gangue. The device is used for separating coal mined from a working face through a continuous process, can be mounted in a crossheading or a main roadway to realize separation of coal and gangue, and is different from the conventional device limited in a single chamber.

Description

technical field [0001] The invention relates to an intelligent coal gangue sorting device based on continuous transportation of belts in a coal mine, belonging to the technical field of coal mining. Background technique [0002] As a large coal country, coal gangue separation has always been a very important part in the coal mine production process for a long time. This process is generally carried out when the coal material is transported to the ground; It will pose a considerable threat to the environment and cause serious pollution. Therefore, it is necessary to keep the gangue out of the well as much as possible, and to separate and use the gangue underground is a problem that coal mining enterprises should focus on in the future. Most of the processing devices are centralized processing in a single chamber, which not only needs to open up a new chamber, but also affects production because of the intermittent transportation, and the equipment is fixed, and a new chamber ...

Problems solved by technology

[0002] As a large coal country in my country, the separation of coal and gangue has been a very important link in the coal mine production process for a long time. This process is generally carried out when the coal material is transported to the ground; etc. will pose a considerable threat to the environment and cause serious pollution; therefore, it is a problem that coal mining enterprises should focus on in the future to ensure that the gangue does not go out of the well as much as possible, and to separate and utilize the gangue underground. Most of the processing devices are concentrated in a single chamber, which not only needs to open a new chamber, but also affects production because of the intermittent transportation, and the equipment is fixed, and a new chamber needs to be opened when moving; therefore, there is an urgent need for a new chamber. Coal and gangue separation device that does not affect underground production and is easy to disassemble and assemble during continuous transportation
