Description
Technical Field
[0001] The utility model relates to the technical field of concrete mixers, in particular to a concrete slurry mixing mixer. Background Art
[0002] Concrete slurry mixing mixer is a machine that mixes cement, sand and gravel aggregates and water into concrete mixture. It is mainly composed of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device. According to the working nature, it can be divided into intermittent (batch) and continuous type; according to the mixing principle, it can be divided into self-falling type and forced type; according to the installation method, it can be divided into fixed type and mobile type; according to the discharging method, it can be divided into tipping type and non-tipping type; according to the mixing drum structure, it can be divided into pear type, drum type, double cone type, disc vertical shaft type and round groove horizontal shaft type, etc. However, there are still some concrete slurry mixing mixers that use manual direct feeding method, which is to move the materials to a higher place and pour them into the concrete mixer. The manual labor intensity is large, the efficiency is low, and there are certain safety hazards. In addition, the internal discharge is not clean enough, and some mortar will stick to the inner wall and is difficult to clean. Therefore, we have launched a new concrete slurry mixing mixer.
