Description

Technical Field

[0001] This utility model relates to the field of pneumatic grouting pump technology, and in particular to a mining pneumatic grouting pump that prevents clogging of the grout suction end. Background Technology

[0002] Pneumatic grouting pumps for coal mines use working media such as slurry and gas to transmit pressure signals, thereby achieving closed-loop automatic control performance. Existing grouting pumps have graduations marked on the material cylinder. During use, water needs to be added before material is added. During stirring, splashing or overflow is easy. The drain valve at the bottom of the material cylinder is prone to water accumulation, making cleaning inconvenient and prone to clogging after use.

[0003] This invention improves the cylinder structure of a pneumatic grouting pump and designs a mining pneumatic grouting pump that prevents clogging of the grout suction end, thereby solving the above-mentioned problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A mining pneumatic grouting pump for preventing clogging of the grout suction end includes a material bucket with a horizontal mounting frame on the bucket. A mixing device and a pneumatic grouting device are vertically mounted on the mounting frame at opposite ends. The upper edge of the material bucket is bent outwards horizontally to form a platform, and the mounting frame is fixed on the platform. A first mounting plate is fixedly mounted on one end of the mounting frame for mounting the pneumatic grouting device, and a slide is provided on the other end. A second mounting plate is slidably connected to the slide for mounting the mixing device. A drain valve is provided at the bottom of the material bucket wall.

[0007] The outer wall of the material barrel is equipped with a baffle, which is cylindrical. The top edge of the baffle is bent inward horizontally to form a limiting ring. The lower part of the inner wall of the baffle is equipped with several limiting blocks. The outer wall of the material barrel is equipped with limiting grooves corresponding to the limiting blocks.

[0008] The carriage includes two horizontally arranged slide rods, with a threaded rod in the center of each slide rod. The threaded rod is threadedly connected to a second mounting plate, and the second mounting plate is slidably connected to the slide rod.

[0009] One end of the threaded rod is equipped with a threaded cap.

[0010] The mounting bracket is fixed to the edge of the platform at both ends with bolts.

[0011] The mixing device includes a mixing motor and a paddle, with the mixing motor fixed to the second mounting plate.

[0012] Pneumatic grouting equipment includes a grouting pump, a grout suction end, and a grout injection end.

[0013] This utility model has the following beneficial effects:

[0014] The slide of this utility model can precisely adjust the mixing device to the center position of the material bucket, thereby effectively forming a vortex, which is convenient for cleaning the cylinder wall and pump head; the pull-out baffle on the outer wall of the material bucket effectively prevents mud from overflowing and contaminating the outer wall, and the cylindrical baffle occupies little space; the detachable mounting bracket installed by bolts makes it easy to disassemble and deeply clean the suction end and blades.
