1. A mechanical, built-in rotating plate adjusts the hopper discharge opening size, allowing for stepless control of the concrete spraying volume and enabling long-distance concrete delivery.
2. The hopper seat automatically flips and the rotor body automatically lifts when removed, reducing maintenance labor.
3. Automatic lubrication of the joint surface between the connecting plate and the steel liner ensures a tight seal, effectively reducing wear on moving parts, preventing compressed air leakage, and improving compressed air utilization.
4. A hydraulic clamping system automatically zones the clamping force for precise control.
5. An automatic accelerator dosing system precisely controls the amount of accelerator added.
6. The overall machine structure is more compact, making it easier to move between sites.
