The invention discloses an automatic loading shotcrete machine for a coal mine. The automatic loading shotcrete machine is provided with a chassis equipped with bottom wheels; a sliding plate is arranged above the chassis; a traveling oil cylinder is connected between the chassis and the sliding plate which is fixed with an operation platform and a hydraulic station; a guniting device is supported on the sliding plate through a rotary device; a lifting oil cylinder is fixedly connected with the guinting device; a piston rod of the lifting oil cylinder is connected with a loading device; a discharge outlet of the loading device is corresponding to a feed inlet of the guniting device; and hydraulic power of the hydraulic station is connected with the traveling oil cylinder, the lifting oil cylinder and the loading device through a hydraulic pipeline. The loading device is a scraper conveyor comprising a machine frame, a scraper chain and a traction motor. The invention is used for guniting to treat tunnel surface under the coal mine, enables loading and guniting to unify through machines, completely eliminates damages from dusts generated from underground manual mixing and loading on worker bodies. The invention has the advantages of low resilience rate, good guniting face quality, greatly improved advancing drilling depth and enhanced work efficiency. The device is driven hydraulically and can realize stepless speed regulation with safe, reliable and stable operation.
Description
Technical field: [0001] The invention relates to an automatic feeding and spraying machine for coal mines, which is used for spraying the surface of roadways in underground coal mines. Background technique: [0002] The existing methods of grouting in the underground tunnels of coal mines, such as manual underground mixing and manual feeding, are not only labor-intensive and labor-inefficient, but also produce a large amount of dust in the environment, which seriously affects the health of workers. At the same time, the high rebound rate of the shotcrete and the poor quality of the shotcrete surface greatly restrict the safety and stability of the excavation work, and urgently need to be improved. Invention content: [0003] The purpose of the present invention is to provide an automatic feeding and spraying machine for coal mines, which can realize the function of automatic feeding and spraying, and solve the problems of high labor intensity, low labor efficiency and envi...
