Abstract

The invention discloses a guniting device for a coal mine tunnel and belongs to the technical field of guniting equipment. The guniting device comprises a frame and a guniting mechanism, a material overturning mechanism, a material conveying mechanism and a position adjusting mechanism are arranged at the top of the frame; the position adjusting mechanism comprises an angle adjusting assembly anda rotating assembly; four traveling wheels are arranged at the bottom of the vehicle frame, the guniting mechanism comprises a rotating table, a rotating arm, a material stretching assembly and a material scraping assembly, a fixing base and a mounting base are arranged at the top of the rotating table, a hydraulic cylinder is arranged on the fixing base, and the output end of the hydraulic cylinder is hinged to one end of the rotating arm. According to the guniting device, raking operation can be conducted on blasted small stones in a small space through the raking assembly; by means of the angle adjusting assembly, the adjusting plate can rotate, so that a guniting head can conduct guniting operation at different angles, raw materials can be poured into a material storage cabinet insteadof manual work through the material overturning mechanism, and workers do not need to conduct pouring operation.

Description

technical field [0001] The invention relates to the technical field of spraying equipment, in particular to a spraying device for coal mine roadways. Background technique [0002] During the excavation process of the coal mine, the gas gushes out rapidly, and the gas content in the ventilation often exceeds the limit, making it difficult to carry out the operation smoothly. In order to stabilize the rate of gas gushing and reduce the frequency of overruns, the mine currently adopts the method of hanging net shotcrete to close the roadway and the method of shotcreting the coal wall of the underground shotcrete material, usually cement, sand, gravel and other materials on site. Stir, and then use a shotcrete machine or a grouting machine to directly spray it onto the coal mine rock formation. After the cement material is solidified, it can play the role of closed support to slow down the gas gushing out of the coal wall. The existing shotcrete machine has a structure The di...
