Abstract

The invention relates to control of a coal mine underground transfer point unloading device and a coal flow system, in particular to a multi-loading point coal flow control system which comprises an unloading hopper, an unloading hopper opening on-off drive device and an automated control system, wherein the opening position at the bottom of the unloading hopper is articulated with a fan-shaped gate, and an unloading hopper switching-on travel switch and an unloading hopper switching-off travel switch are installed on the fan-shaped gate; the unloading hopper opening on-off drive device comprises an forward and inverse rotating roller winch installed on a top plate of a belt lane top and two fixed pulleys; a steel wire is wound on the roller winch; one end of the steel wire is fixed at the free end of the fan-shaped gate after passing through the right fixed pulley, and the other end is fixed at the free end of the fan-shaped gate after sequentially passing through the right fixed pulley and the left fixed pulley. The invention has simple structure, convenient installation and use, safety and reliability, reduces the accident rate and solves the serious problems of pressed transmission rubber belts, burning-out motor, influenced normal production order, and the like.

Description

(1) Technical field [0001] The invention relates to the control of unloading device and coal flow system at transfer points in underground coal mines, in particular to a multi-loading point coal flow control system for multi-point unloading of a belt conveyor and centralized control of coal flow blocking. (2) Background technology [0002] In the production system of the mine, due to environmental and human factors, especially the needs of on-site work, unloading devices are installed in the underground production coal flow system, and the methods include pneumatic, hydraulic and manual; the life of the conveyor belt is very large. To a certain extent, it is related to the structure of the feeding device. Post workers often operate the underground unloading device; these methods are very simple, but they cannot control the amount of coal unloaded by each unloading of the coal flow system, cannot grasp whether each parameter of the coal flow system meets the requirements, and...
