　　The lifting and spraying machine improves work efficiency, without stopping the machine, and can work continuously. The hopper automatically loads materials, saving manual labor. The size of the machine can be selected according to the construction environment to facilitate construction and increase workload. In terms of machine operation, it is also very user-friendly. The machine can start working as soon as it arrives, and everyone can operate it.

　　Working principle (1) Before starting up, read the manual carefully. 2. Unscrew the cover of the air filter on the fuel tank and inject 90 liters of clean anti-wear hydraulic oil No. 32 or No. 46 into the tank. The refueling height can be observed by the oil gauge next to the control switch inside the tank. When the tipping bucket is in position, the height of the hydraulic oil in the oil tank should be observable within the oil gauge. As the oil level is lower than the oil gauge when the cylinder is raised, the oil level height is above the oil gauge. 3. Open the bolt of the sprayer to add gear oil, add gear oil, and see the oil from the oil window position. 4. Turn on the spraying unit near the spraying working face. 5. Connect the three-phase 380V power supply and observe whether the voltage displayed on the voltmeter on the control board of the electrical control box is around 380V. If the voltage is lower than 360V, it is strictly prohibited to turn on the machine, otherwise the machine will not work properly due to low voltage. 6. Confirm the start button of the forward and reverse point-to-point spraying machine motor, observe whether the motor direction is the same as the marked direction. If it is different, the correct direction can be determined by adjusting the phase (the direction of this machine has been adjusted before leaving the factory). Confirm the use of the oil pump motor for the slope support hoisting type spraying machine and the Jingheng mine care spraying unit.

　　Shocked concrete has the characteristics of fast strength growth, strong bonding strength, high density, and good impermeability. It can effectively fill the cavities between rock blocks, increase the integrity of the surrounding rock, prevent weathering and loosening of the free surface, and work together with the surrounding rock. Compared with ordinary cast concrete, shotcrete construction combines several processes such as conveying, pouring, and compacting into one, without the need for formwork, making the construction fast and simple. Shocked concrete can play a bearing role early on. Experiments have shown that compared to cast concrete, sprayed concrete has poorer compactness and stability. Due to the many advantages of shotcrete, it is necessary to mechanize it to improve its spraying efficiency, and concrete sprayers have emerged. Spray concrete technology is a key technique that needs to be applied in tunnel construction. In the application process, this technology mainly relies on concrete spraying machinery - wet spraying machine, which sprays concrete with added quick setting agent onto the surface of structures or rocks, promoting the effective strengthening and protection of structures or rocks. The application of wet shotcrete technology has many advantages, so its application in the construction process is becoming more and more widespread. Slope support hoisting type shotcrete machine and Jingheng mine care shotcrete unit are being used.
