Embodiment Construction
[0044] The present invention will be described in further detail below in combination with 21 drawings and embodiments.
[0045] attached figure 1: Schematic diagram of the mechanical equipment and construction method for mud backfilling in the goaf of the mine. The speed-regulating hoist (1) is placed on the top of the cliff side of the excavation surface (2) of the loess mountain body. The hoisting wire rope (3) is wound on the drum of the speed-regulating hoist (1), and its end is hung with a double-shaft reciprocal (clockwise and counterclockwise) three-way (radial, end-to, oblique) rotation Mowers (4). The two-axis reciprocal (rotating clockwise and counterclockwise) three-way (radial, end-oriented, and oblique) rotary soil cutter (4) is close to the excavation surface (2) of the loess mountain to perform up-and-down reciprocating cutting motion. The loose soil material (5) that has been cut and stripped from the mountain body falls and accumulates on the soil field at...
