Shaftless spiral automatic proportioning concrete mixing conveyor

Abstract

The invention provides a shaftless, spiral and automatically-mixing concrete stirring and conveying machine and relates to the technical field of concrete stirring and conveying equipment. The shaftless, spiral and automatically-mixing concrete stirring and conveying machine comprises a conveying and stirring main drive shaft and a conveying and stirring driven shaft which are parallel to each other, and the conveying and stirring shafts are each provided with a feeding segment and a stirring and mixing segment from the head end to the tail end in the conveying direction; a shaft body, at the position of the feeding segment, of the conveying and stirring main shaft is provided with a spiral sand feeding spiral piece, the heal end of the conveying and stirring driven shaft is provided with the corresponding feeding segment in the conveying direction, a shaft body, at the position of the feeding segment, of the conveying and stirring driven shaft is provided with a cement feeding spiral piece, and the two feeding spiral pieces are contrary to each other in the turning direction as well as the rotation direction; shaft bodies, at the stirring and mixing segments, of the two conveying and stirring shafts are provided with hollow and shaftless big spiral pieces, and inner diameter spaces of the stirring big spiral pieces are provided with stirring small spiral pieces contrary in turning direction. By means of the shaftless, spiral and automatically-mixing concrete stirring and conveying machine, stable and precise mixing and reciprocating slurry stirring can be achieved, stirring can be more sufficient, efficiency is higher, and the shaftless, spiral and automatically-mixing concrete stirring and conveying machine is suitable for application and popularization.

Description

Technical field: [0001] The invention relates to the technical field of concrete mixing and conveying equipment, in particular to a shaftless screw automatic proportioning concrete mixing conveyor. Background technique: [0002] Concrete is a commonly used building material in the field of construction. When used, it needs to be mixed in a certain proportion, then added with water and stirred with a mixing device, and then laid or poured into shape. The supporting mixing equipment is also required to mix concrete in the grouting and spraying construction of the mine. Because the existing mixing equipment suitable for this kind of operation is generally mixed by manual batching and then placed in the mixer, the stability and accuracy of the batching ratio are low. It is not high, and most of them are intermittent mixing and feeding, and they are not concentrated on one equipment, so continuous and stable concrete preparation cannot be realized. Prior art application number: ...

AI Technical Summary

Problems solved by technology

The supporting mixing equipment is also required to mix concrete in the grouting and spraying construction of the mine. Because the existing mixing equipment suitable for this kind of operation is generally mixed by manual batching and then placed in the mixer, the stability and accuracy of the batching ratio are low. It is not high, most of them are intermittent mixing and feeding, and they are not concentrated on one equipment, so it is impossible to achieve continuous and stable preparation of concrete

Prior art application number: CN201310266603.1 disclosed invention patent, because sand and cement are not transported according to their respective channels, it is easy to have inaccurate ratios, and the ratio of concrete produced by one equipment is unique, and cannot produce A variety of concrete ratios are produced to meet the needs of projects. When cleaning after use, a lot of concrete is adhered to the shaft and accessories on the shaft, which is difficult to clean and needs to be improved.
