Using independent drive, microcomputer control, constant-speed automatic control systems. The diesel-powered SC9DK220 diesel engine has a powerful power of 162kW. Adopting a three-in-one powerful composite radiator, the transmission and distribution adopt four sets of independent hydraulic system transmission, automatic material level control, ultrasonic sensor control technology for material distribution, and ultrasonic or material control technology for feeding materials to ensure the material trough. The material level is stable. The height of the dividing device can be conveniently moved up and down to accommodate different paving thicknesses and reduce segregation. High wear-resistant alloy materials are used for the material-dividing blades, and highly wear-resistant steel plates are used for the material conveying floor and the screed bottom plate to effectively extend the service life of the machine. Central centralized lubrication system can automatically evenly lubricate bearings in high temperature parts.
