Circular stirring concrete stirrer

Abstract

The invention relates to the field of concrete preparation, in particular to a circular stirring concrete stirrer. The circular stirring concrete stirrer comprises a motor II, a spindle, stirring blades and ramming blades. According to different concrete mixing degrees, different stirring modes are employed, so that the stirring efficiency and the stirring effect are improved and the service lifeof rotary stirring equipment is prolonged. In an early stirring operation, a push-stirring plate moves left and right to a great extent for large-scaled initial stirring, and meanwhile, a rotary stirring mechanism composed of the stirring blades and the ramming blades stir concrete at fixed points, so that the work strength of the rotary stirring mechanism in the early stage is reduced. In the middle and later periods of stirring operation, the push-stirring plate moves leftward to push the initially stirred concrete to the rotary stirring mechanism to be stirred more finely, and then the push-stirring plate is elevated to move rightward, so that the finely stirred concrete flows back to the right side naturally to be circulated. So repeatedly, it is convenient to stir the concrete quicklyin a large volume container and the stirring effect is uniform.

Description

technical field [0001] The invention relates to the field of concrete preparation, in particular to a circulating mixing concrete mixer. Background technique [0002] For example, the publication number is CN206551220U a kind of concrete mixer, which includes a mixing bucket, and also includes a rotating drum vertically arranged in the mixing drum with openings at both ends, a first helical blade fixed on the inner wall of the rotating drum, and used to drive the mixing drum. The first power part for rotating the rotating drum, the stirring shaft inserted in the rotating drum, the second helical blade fixed on the stirring shaft, the second power part for driving the rotating shaft, the rotating The rotation direction of the drum is opposite to the rotation direction of the stirring shaft. The utility model has the following advantages and effects: the first power part is used to drive the rotating drum, and the second power part is used to drive the stirring shaft to rotat...

AI Technical Summary

Problems solved by technology

However, when the volume of the mixing tank is much larger than that of the rotary mixing mechanism, the mixer has a low discharge efficiency. It cannot mix a large amount of concrete when the intensity of the concrete mixing operation in the early stage is high, and it cannot perform more detailed mixing in the mixing operation of the concrete in the middle and later stages. , and it is not convenient to control the mixing degree of concrete, and it is prone to local over-mixing or insufficient mixing effect
