　　Seller of Double material Bucket Lifting Spray Machine and Jingheng Water Diversion Culvert Spray Unit

　　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.

　　Construction steps for material spraying on concrete spraying unit:

　　1. The transport vehicle pours concrete materials directly into the flipping bucket through the feeding support. The concrete material is a wet sprayed material, and its moisture content should not exceed 0.2, otherwise it will affect the discharge port.

　　2. Press the oil pump switch, the oil cylinder fixed on the bracket will flip up the tipping bucket, pour the material into the upper storage hopper, turn off the oil pump motor, and lower the tipping bucket.

　　3. Turn on the switch of the spraying machine and start spraying according to the spraying requirements.

　　4. When the material in the hopper of the sprayer is lower than the screen mesh, jog the vibration motor switch of the upper storage hopper to control the discharge.

　　5. When the material in the upper storage hopper is almost used up, repeat the operation of (2) to complete a cycle.

　　6. When there is too much accumulation of large particles on the sieve in the hopper of the sprayer, the particles should be cleaned up in a timely manner. The seller of the double hopper lifting sprayer Jingheng diversion culvert spraying unit should be responsible for the cleaning of the particles.

　　Spray concrete operation process: Before starting the spray concrete operation, an old belt should be laid on the spraying site to collect rebound material, with a rebound rate not exceeding 10%. Boil water and adjust the water volume to maintain a pressure of no less than 0.4 MPa. The water pressure should be about 0.1 MPa higher than the pressure, and the amount of water added should be controlled based on the experience of the shooter. The water cement ratio should be 0.4. The sprayer operates the nozzle to flush the rock surface from top to bottom. The concrete spraying machine is powered on and sprayed with material. Adjust the air flow rate again according to the feeding situation to ensure that there are no dry spots, no flow, strong adhesion, and less rebound material on the sprayed surface. The spraying is carried out in sections from bottom to top, starting with the wall and then the arch. When spraying, the nozzle should be as perpendicular as possible to the sprayed surface, with an angle not less than 70 degrees. When spraying, the nozzle should move in a spiral shape, uniformly and slowly moving with a diameter of 200-300mm and a circle pressing against a semicircle. The concrete spraying machine sprays concrete with a thickness of 50-70mm at a time, and it should be re sprayed in a timely manner, with an interval of no more than 2 hours between re spraying. Otherwise, use high-pressure water to rinse the sprayed surface again. Two people should be assigned, one to hold the nozzle for spraying, and one to assist with lighting and be responsible for communication, observing the safety of the roof and the quality of spraying. Operation method for stopping the concrete spraying machine: After the spraying of concrete is completed, operate in the order of stopping the material first, then stopping the water, then cutting off the power, and turning off the air. After the spraying work is completed, remove the nozzle, clean the water ring and the mortar or material inside and outside the sprayer, and coil the air and water pipes. Clean and collect rebound materials, and use up the mixed materials on duty. After spraying concrete for 2 hours, watering and curing will begin. 28 days later, core testing will be conducted to determine the strength of the double hopper lifting type spraying machine and the seller of the Jingheng diversion culvert spraying unit.
