Abstract

The invention relates to a continuous backfilling gangue projection system and belongs to the technical field of mine extracting equipment. The continuous backfilling gangue projection system is arranged on an inner track of a roadway. The projection system comprises a feeding belt conveyer and a projection belt conveyor, wherein the projection belt conveyor is connected with the discharge end ofthe feeding belt conveyor, and a mounting seat is arranged on the tail portion of the feeding belt conveyer. The mounting seat is connected with a first walking mechanism and is an open hollow cylinder body. The projection belt conveyer is arranged on A second walking mechanism by a rotating table, the rotating table is connected with the feeding end of the projection belt conveyer in a hinged mode. A first extension unit is hinged between the projection belt conveyor and the rotating table, and second extension units are hinged between the two sides of the rotating table and the second walking mechanism respectively. According to the continuous backfilling gangue protection system, the highest projection position can be maintained to achieve continuous movement and continuous filling, theheights of the backfilling bodies are the same, continuous filling of the roadway can be realized during operation, and the filling density and filling rate are increased.

Description

technical field [0001] The invention belongs to the technical field of coal mining equipment, and relates to an underground tunnel gangue filling and projecting system, in particular to a continuous filling gangue projecting system. Background technique [0002] At present, most of the gangue discharged from underground coal mines in my country is still transported underground to the ground, and then discharged to designated areas, forming a unique gangue hill in my country's coal industry over time. The existence of gangue hills not only occupies a large amount of land resources, but also often causes accidents such as spontaneous combustion and landslides, causing serious environmental damage. Dozens of components such as S, P, and C contained in gangue have caused serious damage to the atmosphere, water sources, and soil. different degrees of pollution. With the increasing requirements of environmental protection, coal enterprises are forced to find a way out in the comp...
