The stirrer is compact in structure, convenient to use and high in stirring efficiency.

Description

technical field [0001] The invention relates to the field of construction machinery and equipment, in particular to a novel concrete mixer. Background technique [0002] With the continuous development of concrete materials and construction technology, concrete mixers of various new structures have appeared one after another. The mixer is a machine that mixes cement, sand aggregates and water and mixes them into concrete mixtures. It is mainly composed of a mixing drum. , feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device, etc. Traditional concrete mixing equipment is mostly large concrete mixer, vehicle-mounted or ground-fixed, and the working efficiency of this mixer is relatively high. High, suitable for projects with a relatively large amount of engineering. However, at present, the mixing blades of most concrete mixers cannot change their positions, and cannot fully mix the concrete evenly. Some concret...

[0002] With the continuous development of concrete materials and construction technology, concrete mixers of various new structures have appeared one after another. The mixer is a machine that mixes cement, sand aggregates and water and mixes them into concrete mixtures. It is mainly composed of a mixing drum. , feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device, etc. Traditional concrete mixing equipment is mostly large concrete mixer, vehicle-mounted or ground-fixed, and the working efficiency of this mixer is relatively high. High, suitable for projects with a relatively large amount of engineering. However, at present, the mixing blades of most concrete mixers cannot change their positions, and cannot fully mix the concrete evenly. Some concrete requires manual mixing of concrete, which is time-consuming and laborious. ,low efficiency
