Filling vehicle for backfilling coal mining roadway

Abstract

The invention discloses a filling vehicle for backfilling a coal mining roadway, and belongs to the technical field of coal mining roadway backfill. A U-shaped groove vehicle body of the filling vehicle is internally provided with a lifting U-shaped groove bucket, a corresponding filling opening and a corresponding U-shaped feeding inlet are formed in the upper parts of both a bottom plate of theU-shaped groove vehicle body and a bottom plate of a U-shaped groove body of the U-shaped groove bucket, a supporting frame is arranged at the rear part of the U-shaped groove vehicle body, and wheelsare mounted at the lower end or the lower part of the U-shaped groove vehicle body; a lifting hydraulic oil cylinder is mounted on the supporting frame and connected with a lifting seat at the rear part of the bottom plate of the U-shaped groove body of the U-shaped groove bucket, and the lifting seat can ascend and descend along a lifting sliding channel in the bottom plate of the U-shaped groove vehicle body; the supporting frame is connected with a travelling-type belt conveyor; the filling opening is connected with a conveying belt; and the lifting hydraulic oil cylinder is connected witha hydraulic control device. According to the filling vehicle for backfilling the coal mining roadway, a large amount of coal gangue can be backfilled, filler can be quickly formed, the strength and compactness are improved, stacking is facilitated, a coal mining area is filled fully, the gap is eliminated, and the filling strength and compactness are enhanced.

Description

technical field [0001] The invention belongs to the technical field of coal mining roadway backfilling, in particular to a filling vehicle for backfilling coal mining roadway. Background technique [0002] Backfilling of coal mining roadway is to solve the impact of mining subsidence on ground buildings and industrial and agricultural production, and the problem of environmental hazards caused by coal gangue stacked on the ground after being lifted into the well, as well as the "three downs" (underwater, under the road, under the building) Filling after coal mining is a common problem faced by the coal industry. [0003] At present, the backfilling of the coal mining roadway after mining is generally carried out by drilling and grouting. Although this method solves the problem of backfilling the goaf, it is easy to form a conical filling body in the goaf and form a huge filling gap, which will lead to the collapse of the goaf and affect the later treatment work; moreover, ...

AI Technical Summary

Problems solved by technology

Although this method solves the problem of backfilling the goaf, it is easy to form a conical filling body in the goaf and form a huge filling gap, which will lead to the collapse of the goaf and affect the later treatment work; moreover, The utilization rate of coal gangue is not high, causing harm to the environment; the third, even if the filling is complete, the density and strength of the filling body are not high, which will easily cause the goaf to collapse and affect the later treatment work
