Mixer scraper
The JWZ scraper drive device adopts a single-stage worm gear speed reduction transmission, which can be driven by a pendulum needle reducer, an adjustable speed motor through a chain wheel chain, a triangular belt wheel belt, or directly connected. This equipment is a low-speed wheel-output transmission device, with large output torque, low noise, stable operation, and no leakage. It is mainly used for water treatment equipment and mud scraper mechanical matching products. The reducer comes in various forms, including manual lifting, manual-electric dual-purpose lifting, etc. Depending on user requirements, safety shear pins and spring-type overload automatic protection devices (JGZ4500) can be added to ensure the safe operation of the speed sleeve equipment.
