Description
Technical Field
The utility model relates to an conjuncted buffering coal bunker and corresponding colliery crossheading rubber belt conveyor system.
Background
In the coal mining process, coal mined on a working face needs to be conveyed out through a gate-way rubber belt conveyor in a belt roadway. The adjacent crossheading belt conveyors are connected through the coal sliding hopper, once a certain crossheading belt conveyor or a peripheral system of the certain crossheading belt conveyor needs to be overhauled or has a fault, all the upstream crossheading belt conveyors and all the working face conveyors need to be stopped, particularly, the fully-mechanized excavation working face is stopped without completing a cycle, so that the head-on empty top of the fully-mechanized excavation working face is caused, the roof support is extremely unfavorable, the coal mining continuous operation is not facilitated, and the underground safety is not facilitated.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is how to fill the above-mentioned blank of prior art, provide a conjuncted buffering coal bunker and corresponding colliery crossheading rubber belt conveyor system that is favorable to in succession coal mining and working face roof to strut.
In order to solve the technical problem, the conjoined buffering coal storage bin comprises a rack and a coal sliding hopper, wherein the coal sliding hopper is fixed on the rack, the upper opening of the coal sliding hopper is large, and the lower opening of the coal sliding hopper is small, and the conjoined buffering coal storage bin is characterized in that: the coal chute is characterized in that the number of the coal chute buckets is two or three, the coal chute buckets are sequentially arranged and fixed along the crossheading direction, a gate valve is arranged at the lower opening of each coal chute, and the gate valves are driven by a hydraulic telescopic cylinder or a manual lead screw nut mechanism. By the design, when the downstream belt conveyor breaks down, coal flow produced by the coal face can be temporarily stored in the conjoined buffering coal storage bin and the corresponding coal mine crossheading belt conveyor system without stopping coal mining and conveying operation of the face. When the coal chute is used, only the gate valve of the coal chute hopper in use is opened, and the gate valves of other coal chute hoppers are closed. After one coal sliding hopper is filled, the other coal sliding hopper is switched to. Two or three coal chutes are combined, so that the buffering capacity can be doubled or doubled.
Preferably, the lower edge of the side plate at the downstream end of the coal chute hopper at the most downstream is provided with an inverted V-shaped notch, and the lower edges of the side plates at the two sides of the inverted V-shaped notch are respectively fixed with a rubber plate. By the design, the coal flow of the upper layer rubber belt of the crossheading rubber belt conveyor is high in the middle and low on two sides, and can contain more coal than flat coal flow in the same length, so that the coal conveying capacity of the rubber belt conveyor is improved.
This colliery crossheading band conveyer system includes many crossheading band conveyer, and above-mentioned crossheading band conveyer sets gradually its characterized in that along the belt lane: the combined buffering coal storage bin is arranged between the adjacent crossheading belt conveyors, the rack of the combined buffering coal storage bin stretches over the tail of the downstream crossheading belt conveyor between the adjacent crossheading belt conveyors, the lower opening of each coal chute hopper is over against the upper layer of rubber belt of the tail of the downstream crossheading belt conveyor, the tail end of the machine head of the upstream crossheading belt conveyor between the adjacent crossheading belt conveyors is provided with a telescopic extension frame, the tail end of the extension frame is provided with a tail end roller, the rubber belt of the upstream crossheading belt conveyor spans the tail end roller, and the tail end roller of the machine head can move to the tail end of each coal chute hopper along with the telescopic extension frame and is fixed above each coal chute hopper.
By the design, the coal mine crossheading belt conveyor system solves the key technical problems of short-time storage, transfer and adjustment of the coal and gangue quantity when the working face belt conveyor transports the coal and gangue, reduces the phenomenon that the fully-mechanized excavation working face is empty because of incomplete circulation, reduces the influence time of the peripheral transportation system on the operation of the working face belt conveyor, and improves the starting rate of the working face. The method can be widely applied to the field of direct lapping and transferring of the conveyor, and is suitable for various large coal mines.
