Abstract
The utility model discloses a coal-baffle device, which is composed of a coal-baffle plate, a coal-baffle support frame, a coal-baffle curtain, etc. The utility model can be applied to a blasting coal face for preventing the coal form being thrown toward a pavement and a goaf, and thereby, the blasting coal loading rate is increased, the coal shoveling workload is reduced, the labor strength of labors is reduced, and the labor productivity and coal face yield are increased. The utility model has the advantages of simple structure, convenient operation, and safety.
Description
The utility model relates to a kind of retaining device for coal, particularly blasting coal mining driving surface and prevents that the old man from collapsing the retaining device for coal of coal.
The production technology of blast mining face mainly is to drill and blast to carry out coal blasting, the coal part of avalanche of blowing out drops in big gun road and the chute, a part is thrown into footway and old man, therefore, it is low to exist the blasting loading rate, and it is big manually to hovel the coal work capacity from one place to another, inefficiency, the old man is collapsed coal and is reclaimed shortcomings such as difficulty, affects the raising of blast mining face labor efficiency.
The purpose of this utility model provides a kind of retaining device for coal, and it can prevent that coal blasting from throwing to footway and old man, and coal is blocked in the chute.
The purpose of this utility model is achieved in that welded connection plate on the chute of slat conveyer, by joint plate and bolt spillplate is fixed on the chute, the lower link axle is installed on the stay bearing plate of spillplate, the bottom bracket and the retaining coal frame of retaining coal support are installed on the lower link axle, bottom bracket connects with tilted supporter with last coupking shaft by pin respectively mutually with retaining coal frame, forms the retaining coal support.On the retaining coal support Coal-baffle is installed.During the coal-face coal blasting, the opposite collapses the coal that comes, the bottom fall into chute in stopping of spillplate, the coal on top falls into chute in Coal-baffle, stopping of coal support of retaining, thereby stopped that effectively coal throws to footway and old man, realized the purpose of retaining coal.
Owing to adopt such scheme, can be blocked in coal in the chute effectively, improve the blasting loading rate, reduce and manually hovel the coal work capacity from one place to another, reduce labor strength, raise labour productivity and coal-face output.And spillplate, Coal-baffle, retaining coal support three both can unite use, also can use separately.It is simple in structure, is easy to remove and install, and is very easy to use.
The utility model is described in further detail below in conjunction with accompanying drawing:
