Abstract

A rapid filling mechanism for filling a coal mining conveyor mainly comprises an internal groove, an external groove, an inclined hydraulic jack, a horizontal hydraulic jack, steel wire ropes, a fixed steel plate, pulley wheels, an adjusting pushing plate, a pushing hydraulic jack, pushing plates, a slippage seat, frame connected hydraulic jacks and swing hydraulic jacks. The rotation of the internal groove and the external groove is achieved through the extension and retraction of the horizontal hydraulic jack and the extension and retraction motion of the external groove is achieved through the extension and retraction of the inclined hydraulic jack, so that the stacking positions of discharged solid filling materials are adjusted according to the filling requirement. The pushing plates are adjusted to slide along guide chutes through the extension and retraction of the pushing hydraulic jack to achieve the adjustment of the size of the working area of a pushing plate assembly. The adjusting pushing plate and the pushing plates are driven to operate through the extension and retraction of the swing hydraulic jack. The rapid filling mechanism for filling the coal mining conveyor has the advantages of being capable of effectively reducing negative influence to the mining work due to the splashing of the filling materials, improving the filling efficiency and filling effect and being simple in structure, easy to operate, low in investment and wide in practicality.

Description

technical field

[0001] The invention relates to a coal mine underground comprehensive mechanized filling device, in particular to a coal mining conveyor fast filling mechanism suitable for coal mine comprehensive mechanized solid filling. technical background

[0002] For a long time, coal has been the main energy source in our country. As a traditional and basic industry of the national economy, the coal industry plays an important role in the development of the national economy and promotes the rapid economic growth and social progress of our country. However, in coal mining, due to the destruction of the original stress balance state inside the overlying strata in the stope, stress redistribution occurs inside the strata, resulting in deformation, movement, separation, fracture and collapse of the overlying strata in the stope, and finally causes the surface Large-scale subsidence, migration of groundwater, damage to surface structures and deterioration of the ecological ...
