The invention relates to a wet-stirring hydraulic concrete jetting machine for coal mines. The wet-stirring hydraulic concrete jetting machine comprises an emulsion tank, an emulsion power pump, a concrete stirring device, a hydraulic concrete delivery pump, a first water pipe, a concrete delivery pipe and a jetting head. The emulsion tank, the emulsion power pump and the concrete stirring device are sequentially connected, the first water pipe is connected to a continuous stirring tank of the concrete stirring device, and the concrete stirring device is disposed above the hydraulic concrete delivery pump to form an assembly. A discharge outlet of the concrete stirring device is arranged right above a concrete bucket of the hydraulic concrete delivery pump, and the hydraulic concrete delivery pump and the jetting head are connected through the concrete delivery pipe. By the wet-stirring hydraulic concrete jetting machine for coal mines, wet concrete jetting support is fundamentally realized in a coal well, dust is obviously eliminated, the working environment of the concrete jetting support is improved, and safety and health level of coal mine workers is enhanced.
Description
technical field [0001] The invention belongs to the field of concrete spraying machines, in particular to a wet mixing hydraulic concrete spraying machine for coal mines. Background technique [0002] The roadway under the coal mine is a safe space that integrates the functions of coal mine transportation, pedestrians, ventilation and escape. Therefore, the safety support of the roadway is both necessary and very important. There are many ways of roadway support: wooden support, metal support, bracket support, bolt support, anchor net support and concrete shotcrete support, etc., but the safest, most reliable and most common support method is Shotcrete support. At present, the machine used for shotcrete support in coal mines is basically the PZ rotor-type shotcrete machine that has been used for nearly 30 years. Its advantages are small size, light weight, low price, simple operation, and easy for workers to master; Flour dust is large, which poses a great occupational ha...
