7m3/H Remote Dry Concrete Spraying Shotcrete Machine For Tunnel
The PYS7IL-J type mining remote shotcrete machine uses the rotor-type working principle and is fully hydraulically controlled. By increasing the lubrication and hydraulic compression of the friction plate, to improve the sealing performance, reduce the ineffective air consumption, and realize the concrete spraying for long-distance transportation, reduce the labor intensity, and the setting of the dust removal system effectively reduces the dust concentration at the spraying operation site. It has the advantages of quick operation by the on-site operator, less wear of moving parts, high degree of automation, and low cost of use.
1. Stepless adjustment of concrete spraying volume to realize the concrete spraying operation of remote conveying;
2. Automatic lubrication to ensure sealing performance, effectively reduce the wear of moving parts, and improve the utilization rate of air pressure;
3. The clamping device is automatically compressed to ensure precise control of the pressing force;
4. Dust removal system reduces dust emission during operation and protects the physical and mental health of workers;
5. The accelerator is automatically and evenly added, effectively reducing the shotcrete rebound;
6. The hopper seat is automatically rolling over to reduce the labor intensity of maintenance;
7. The crawler chassis runs automatically, which is convenient and fast to move.
1. Combination of hydraulic pressure and machinery to realize stepless adjustment of concrete spraying volume;
2. The lubrication method and automatic lubrication system of the friction pair composed of the friction board and the rotating lining plate;
3. The clamping device suitable for remote conveying is automatically compressed by regional hydraulic pressure;
4. Automatic control of the system.
