Abstract

The invention relates to an automatic mine filling pipeline switching device. The automatic mine filling pipeline switching device comprises a bracket, a connecting pipe, a swing pipe oil cylinder and a pressing oil cylinder, wherein a feed port is formed at one end of the bracket; a plurality of discharge ports are formed at the other end of the bracket; the inlet end of the connecting pipe is fixedly connected and communicated with the feed port; the outlet end of the connecting pipe is connected with the swing pipe oil cylinder and is selectively communicated with one of the plurality of discharge ports under the action of the swing pipe oil cylinder; the pressing oil cylinder is provided with a telescopic piston rod; and when the piston rod stretches out, the outlet end of the connecting pipe can be pressed on the discharge port communicated with the outlet end.

Description

Technical field [0001] The invention relates to a mine filling pipeline, in particular to an automatic switching device for the mine filling pipeline. Background technique [0002] Mine filling is a common treatment method for mine goafs at this stage. Normally, risers and flat pipes are used for mine filling to connect the underground goaf. The risers and flat pipes are used to transport filling materials from the ground to the underground goaf, so that the underground goaf has a certain structural strength to avoid cavings and ground subsidence. The occurrence of geological hazards. [0003] When filling a mine, the filling material usually has a relatively high viscosity and a relatively high roughness, and pipe blockage accidents often occur in the filling pipeline. Restricted by the structure of the filling pipeline, the riser pipe is rarely blocked, and the pipe blockage often occurs in the flat pipe at the bottom of the well. Once a pipe blockage accident occurs, it will ...
