The self-loading concrete mixer is a fully integrated engineering vehicle that combines automatic loading, mixing, transport, and discharge into a single unit. Its core capability lies in a hydraulically driven system that enables fully automated, on-site concrete production and delivery without the need for external loading equipment.
Power Transmission System
Energy Conversion: The system draws power from the chassis engine via a Power Take-Off (PTO) unit. This mechanical energy is converted into hydraulic pressure by a variable-displacement pump and transmitted to a fixed-displacement hydraulic motor.
Drive Execution: The hydraulic motor powers a reduction gearbox, which drives the rotation of the mixing drum, ensuring a smooth and high-torque power transfer for efficient operation.
Automatic Loading Process
Material Scooping: The vehicle features an integrated loading arm and bucket. The operator maneuvers the arm to scoop aggregates, cement, and other raw materials directly from the ground, eliminating the need for a separate front-end loader.
Lifting and Feeding: Once loaded, the arm elevates the bucket over the mixing drum. The rear gate opens to deposit the materials precisely into the tank for mixing.
Mixing and Discharge Mechanism
Mixing Operation: During the mixing phase, the drum rotates forward. Internal helical blades blend the materials, capable of handling both plastic and semi-dry hard concrete mixes to ensure homogeneity.
Discharge Operation: Upon reaching the destination, the drum reverses rotation. This action utilizes the internal blades to rapidly and cleanly expel the concrete, ensuring efficient unloading.
