This product is a set of shotcrete, automatic shift, automatic feeding, large comprehensive mining equipment can only be added in an accelerator, which solves the disadvantages of the traditional manual feeding shotcreting, the feeding, spraying two moves through the realization of unified machinery, completely eliminate the previous process of shotcrete mixing on the artificial. The material produce dust on workers health hazards;With low rebound rate and good quality of shotcrete face, it can greatly improve the tunneling speed and work efficiency. It is an efficient equipment for shotcrete bolt support in tunnel construction;

1. High efficiency and low energy consumption. This product is about 30% more efficient than manual injection. Due to the increase in efficiency, the shotcreting time for accomplishing the same amount of work is reduced, thereby reducing the power consumption of the sprayer and the power consumption of the auxiliary equipment in the construction work surface. According to incomplete statistics, it can save about 35% of the electricity for the construction site.
2. Labor and materials
Provincial labor: Tunnel construction is one of the most difficult environments in the existing construction, and it is a high-risk environment. This product features mechanical automatic cutting equipment, which can be easily operated by only 2~3 people.
Material saving: The hopper discharge port is provided with a regulating feed speed gate, which can adjust the cutting speed according to the spraying speed without causing the mixing material to leak to the lower barrel of the spray machine to cause waste of the mixing material.
3. Reduce pollution. First of all, the hopper automatic cutting process is that the hopper discharge port is directly aligned with the lowering of the shotcrete machine, and the mixing material is not subjected to the artificial lifting process, thereby avoiding a large amount of mixture waste and dust pollution generated in the process of popping. Secondly, this product changed the return structure of the original shotcrete machine and completely eliminated the return air dust.
