Mixer is a kind of construction machinery, which is mainly used for mixing cement, sand, various dry powder mortar and other building materials. This is a kind of machine with blades rotating in a cylinder or tank to mix a variety of raw materials into a mixture or suitable consistency. There are many kinds of mixers, including forced mixer, single horizontal shaft mixer, double horizontal shaft mixer and so on.
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 supporting device. According to the nature of work, it is divided into intermittent type (batch type) and continuous type; According to the mixing principle, it is divided into self falling type and forced type; It is divided into fixed type and mobile type according to the installation mode; According to the discharging method, it is divided into tipping type and non tipping type; According to the structure of mixing drum, it can be divided into pear type, drum type, double cone type, disc 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 body is equipped with a gear ring arranged around the drum body, 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 gear and gear ring are meshed, the sliding phenomenon between the supporting wheel and the mixer drum can be effectively overcome in rainy and foggy weather; The transmission mechanism adopted can further ensure the elimination of slip between the supporting wheel and the mixer drum.
