Abstract
The utility model discloses cantilever support and automatically put device for coal, comprise cantilever support back timber, the bottom of described cantilever support back timber is fixedly connected with cantilever support front pillar and cantilever support rear pillar, cantilever support back timber near cantilever support rear pillar is provided with a wheel shaft, described wheel shaft connects one end of a waste rock board, also comprise a hydraulic cylinder, the side of described hydraulic cylinder is connected with described cantilever support back timber, the opposite side of described hydraulic cylinder is connected with waste rock board, described hydraulic cylinder is provided with operating valve, and described operating valve is provided with operating grip.The purpose of this utility model devises a kind of variable coal discharge outlet, and according to putting coal needs, coal discharge outlet can become large.
Description
Technical field
The utility model relates to coal mining field.Be specifically related to cantilever support and automatically put device for coal.
Background technology
Cantilever support coal caving mining method, install a pair fixing waste rock board after the cantilever support of use, after stope moves frame, the coal be caving is blocked in after waste rock board, can not flow into work plane smoothly, needs operating personnel to use length that instrument is outwards taken off coal.Coal discharge outlet is fixed, and can not become large.
Utility model content
The purpose of this utility model devises a kind of variable coal discharge outlet, and according to putting coal needs, coal discharge outlet can become large.
In order to achieve the above object, the utility model has following technical scheme:
Cantilever support of the present utility model puts device for coal automatically, comprise cantilever support back timber, the bottom of described cantilever support back timber is fixedly connected with cantilever support front pillar and cantilever support rear pillar, cantilever support back timber near cantilever support rear pillar is provided with a wheel shaft, described wheel shaft connects one end of a waste rock board, also comprise a hydraulic cylinder, the side of described hydraulic cylinder is connected with described cantilever support back timber, the opposite side of described hydraulic cylinder is connected with waste rock board, described hydraulic cylinder is provided with operating valve, and described operating valve is provided with operating grip.
Further, described cantilever support back timber is also provided with a buffer bar, and described buffer bar is flexibly connected with waste rock board.
Owing to taking above technical scheme, the utility model has the advantage of:
The utility model is according to putting coal needs, and coal discharge outlet can become large.Variable coal discharge outlet device has broken coal cinder simultaneously, automatically puts coal function.
