Description

Technical Field

[0001] The utility model belongs to the technical field of coal mines, and in particular relates to a device for filling coal mine cavities with inorganic materials. Background Art

[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, the coal is usually mined by tunneling underground, which is an underground coal mine. When the coal seam is very close to the surface, the coal is usually mined directly by stripping the surface soil layer, which is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. Coal mines encompass large areas above and below ground, including related facilities. Coal mines are the spaces created by humans when excavating coal-rich geological strata. They typically include tunnels, shafts, and mining faces. After coal mining, cavities are formed. To prevent collapse, these cavities are filled with inorganic materials.

[0003] When filling holes, the existing filling method is to directly use a filling pump in conjunction with a filling nozzle to deliver filling materials. The filling nozzle is directly hung or placed on the ground for fixed-position spraying. This spraying method will cause material accumulation, making it difficult to diffuse quickly and inconvenient to move back and forth, and has certain limitations in use. Utility Model Content

Such a spraying method will cause material accumulation, making it difficult to diffuse quickly and inconvenient to move back and forth, and there are certain limitations in use.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a coal mine cavity inorganic material filling device, comprising a base, wheels are installed at the four corners of the base, a filling pump is installed on the upper surface of the base, the outlet pipe of the filling pump is connected to a telescopic hose, the end of the telescopic hose away from the filling pump is connected to a filling nozzle, a regulator is provided on the base, the regulator comprises a lower shell, a motor is fixedly installed on the inner wall of the lower shell, a threaded rod is fixedly installed on the output shaft of the motor, a threaded plate is threadedly installed on the outer surface of the threaded rod, a connecting plate is fixedly installed on the upper surface of the threaded plate, and the connecting plate slides through and extends out of the lower shell and An upper shell is fixedly installed, and a rotating shaft is fixedly installed on the lower shell and the upper shell, a fixed seat is rotatably installed on the outer surface of the rotating shaft, two sliding frames are slidably installed on the side of the fixed seat, a cross socket is fixedly installed on the side of the sliding frame, and a cross slot for inserting the cross socket is opened at the end of the rotating shaft, the fixed seat at the lower position is fixedly installed on the upper surface of the base, and an outer plate frame is installed on the surface of the fixed seat at the upper position, an inner plate frame is slidably installed in the outer plate frame, the filling nozzle is fixed on the end of the inner plate frame, a cylinder is fixedly installed on the surface of the outer plate frame, a fixed block is fixedly installed on the end of the piston rod of the cylinder, and the fixed block is fixed to the surface of the inner plate frame.

[0011] By adopting the above solution, the disc is rotated in conjunction with the articulated arm. When the disc rotates, the sliding frame can be pulled to move under the action of the eccentrically arranged articulated arm, thereby driving the cross socket to move.

[0015] By adopting the above solution and using it in conjunction with a stabilizing shaft, the threaded rod can be supported to prevent the threaded rod from centrifugal shaking.

[0016] As a preferred embodiment, a guide bar is fixedly mounted on the inner wall of the outer plate frame, and a guide groove for use with the guide bar is opened on the side surface of the inner plate frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are:
