Concrete spraying machine is a device used for wet shotcrete. Compared with dry sprayer and wet sprayer, it has significant advantages such as less operating dust, less spray rebound, protecting working environment, saving raw materials, and improving spray layer quality. And easy to operate and maintain. Adopting the working principle of low-pressure low-speed vortex airflow and close-range jet, it overcomes the problems of pipe blockage, pulse, segregation and so on. Make the jet flow uniform and stable, and improve the quality of the spray layer.

Structure and working principle of concrete spraying machine:

The mixed materials are unloaded into the vibrating hopper from the discharge port of the batching mixer (or artificially mixed and loaded), fed into the hopper of the jet machine through the screen, and injected into the straight-through material cavity of the rotor by the dialer. It rotates with the rotor to the discharge port, where the compressed air passed through the air chamber blows the material into the cyclone. Here, another wind is introduced by the cyclone, which blows and accelerates the material in a multi-headed wind spiral state, and makes it rotate, float, enter the conveying pipe, and then add a small amount of supplementary water to the nozzle and spray it out. The wet shotcrete machine is a bolt-and-shoot support tool with good comprehensive performance such as reducing dust, reducing waste, and saving materials. Wet shotcrete machine is a construction equipment widely used in engineering construction. It uses compressed air or other power to The agitated material matched in a certain proportion is transported through the pipeline and sprayed at a high speed to the sprayed surface to condense and harden.

Application fields of concrete spraying machine:

1. This concrete spraying machine can be widely used in anchor grouting (grouting) grouting, consolidation grouting and backfill grouting for highways, railways, urban rail transit, hydropower stations and other anchor grouting projects.

2. Shotcrete machine can be used for pressure grouting projects such as dams, slopes, and soft rock reinforcement.

3. Gunite machine can be used for the spray protection construction of the bottom layer and cover layer of the inner and outer walls of urban construction projects and other grouting projects. The opening pressure of the safety valve must be adjusted according to the requirements in the table below.

Use and operation of concrete spraying machine:

1. The operator must be familiar with the operating procedures and the main structure of the machine before starting the operation.

2. Before starting the machine, check whether the contacts of each line of the electronic control system are firm and whether there is any leakage.

3. Observe the oil mark and check whether the lubricating oil in the reducer is sufficient or not.

4. The lubricating oil in the main reducer is No. 50 industrial gear oil or No. 30 mechanical oil.

5. Check whether the fastening of each part of the machine is loose.

6. Check the metering pump, see the metering pump manual.

7. Adjust the amount of accelerator added, and adjust the flow rate of the metering pump according to the actual amount of accelerator required in the project.

8. Run the machine for a short time in order to grasp the operation situation.
