The mixer is used to mix concrete.

The mixer is used to mix concrete.

Concrete mixer is a machine that mixes cement, sand aggregate and water to make concrete mixture. It is mainly composed of mixing drum, feeding and discharging mechanism, water supply system, prime mover, transmission mechanism, frame and support device.

According to the working nature, it is divided into batch type (batch type) and continuous type; According to the mixing principle, it can be divided into self falling type and forced type; Fixed type and mobile type according to installation mode; According to the discharging mode, it can be divided into tilting type and non tilting type; According to the structure of mixing drum, it can be divided into pear type, drum type, double cone type, disk vertical shaft type and circular groove horizontal shaft type.

The concrete mixer includes a power mechanism connected with the transmission mechanism through a shaft and a drum driven by the transmission mechanism. The drum barrel is provided with a gear ring arranged around the drum barrel, and the transmission shaft is provided with a gear meshing with the gear ring.

The structure of the utility model is simple and reasonable. After the gears and gear rings are meshed, the sliding phenomenon between the supporting wheel and the mixer drum in rainy and foggy weather can be effectively overcome; The adopted transmission mechanism can further ensure that the slip phenomenon between the supporting wheel and the mixer drum is eliminated.
