Refuse receiving device for coal face supports

Abstract

The present invention relates to a refuse receiving device for coal face supports. The refuse receiving device comprises a fixed bracket and a refuse receiving plate. An upper portion of the fixed bracket is provided with an installing hole. A lower portion of the fixed bracket is bended to form an inclined plate. An included plate is formed between the inclined plate and the horizontal direction.The refuse receiving plate is welded to the inclined plate and arranged to be parallel to the inclined plate. Two ends of the refuse receiving plate are raised up to form baffle plates. One portion of the refuse receiving plate is welded to the inclined plate, and the other portion of the refuse receiving plate is positioned outside the inclined plate without being welded to the inclined plate. The refuse receiving device has the advantages that refuses falling off from gaps between the supports can be effectively cushioned, received and guided, personnel and equipment are prevented from being influenced by the refuses falling off between the supports, and safe production environment is ensured; the refuses can be effectively prevented from falling off by the baffle plates, and can be ensured to fall off in a chute according to a normal guiding program.

[0002] In the mining process of underground coal mining face, affected by geological conditions and other aspects, there is often a phenomenon that the roof of the working face is broken. Strengthening the safety management of the roof during the mining process is a key task that cannot be ignored, and there is nothing in the world. It is seamless and foolproof, and there are often some loopholes or deficiencies. The protection of the roof of the working face is mainly completed by the brackets. The complete support of the roof of the working face is completed by multiple brackets, which are combined into a complete For the roof and floor protection system, due to the position of each bracket and its own design, there are certain gaps between each bracket, which may be large or small. In the process of pulling the bracket or operating the bracket during maintenance, it is inevitable that there will be some gangue. When falling from the gap left between the frames, in front of the pedal of the frame and in the cable groove of the shearer, the increase of gangue will affect the blockage of the push-pull rod and the cable groove of the frame, making it difficult to pull the frame and the cable and cable clamp of the shearer. At the same time, it has brought great safety hazards to the safe construction and walking of personnel on the working face

[0003] Due to the design of the bracket, the side guards and top beams of the bracket only have a certain protection range, and cannot provide effective protection according to the site conditions. At present, there is no protection device specially designed for this problem on the market.
