The concrete auxiliary spraying vehicle (spraying robot) is an intelligent construction solution designed for small and medium-sized tunnel applications. Utilizing a remote-control operating system, this equipment enables precise multi-dimensional coordination between the mechanical arm and spraying mechanism, effectively replacing conventional handheld spraying methods. Key benefits include minimized labor intensity, enhanced operational efficiency, improved spray surface uniformity, and alignment with national policies promoting intelligent transformation in coal mining. Beyond mining tunnels, the system can be adapted for lining support in transportation (road/rail), hydraulic, and urban underground projects through modular adjustments, demonstrating broad industry applicability.

1. Featuring a high-telescoping arm structure and a wide-coverage spraying system, the device ensures extensive concrete application in confined spaces.

2. Equipped with a four-way hydraulic support mechanism, its rapid deployment design and auto-leveling function provide dual stabilization under diverse working conditions.

3. The wireless remote-control platform incorporates safety safeguards, substantially lowering occupational hazards and operator fatigue.

4. An intelligent mixing system dynamically adjusts the water-cement ratio via real-time feedback, optimizing material performance.

5. A multi-axis linkage mechanism, paired with adaptive trajectory control, maintains optimal elevation angles while reducing rebound rates, thereby enhancing spray layer density.

6. The load-responsive hydraulic drive employs hybrid control strategies to balance actuator precision and energy efficiency, boosting overall system performance.
