Visual identification and separation system for belt conveyor in underground coal mine

Abstract

The invention discloses a visual identification and separation system for a belt conveyor in the underground coal mine. A first image acquisition module is fixed above a motor box of a coal mining machine, a mounting bracket is fixed on a middle frame at the outlet end of the belt conveyor in a welding mode, and a supporting baffle is fixedly connected with the mounting bracket through bolts; anda second image acquisition module and an illumination module are fixedly connected to a supporting top plate through screws, a conveyor separator is fixed under the belt conveyor, the conveyor separator comprises two inclined separation baffles, one end of each of the separation baffles is connected with a conveyor separator shell through a hinge, and the other end of each of the separation baffleis connected with a hydraulic rod through a hinge. According to the visual identification and separation system, the coal rock state in the cutting process of the coal mining machine and the coal rock state at the outlet end of the belt conveyor are identified in real time through the visual identification system, through computer analysis and effective control over the separation baffles, rock,gangue and fallen coal mixed with the rock and the gangue are separated out in time, the later sorting workload is reduced, and the sorting efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of coal mining, and in particular relates to a visual identification and separation system for an underground coal mine belt conveyor. Background technique [0002] During underground mining, coal shearers often encounter rocks, gangue, etc., causing the coal to be mixed with impurities such as rocks and gangue. These impurities are transported and stacked together with the coal through the belt conveyor. In order to improve the quality of coal, it is necessary Remove impurities such as rocks and gangue. At present, impurities are mainly removed by sorting coal gangue. This method needs to process a large amount of coal mixed with rocks and gangue, and sort out impurities such as rocks and gangue. The workload is large and The efficiency is low and the cost of coal production is increased. [0003] Therefore, it is necessary to design a visual identification and separation device for coal mine belt conveyor...
