Automatic screw matching concrete stirring conveyer

Abstract

The invention discloses an automatic screw matching concrete stirring conveyer. The automatic screw matching concrete stirring conveyer is provided with two conveying and stirring shafts in parallel; each conveying and stirring shaft is sequentially provided with a primary feeding section, a secondary feeding section and a stirring and mixing section from the head end to the tail end according to the conveying direction; the shaft body of each conveying and stirring shaft at the first feeding section part and the second feeding section part is respectively provided with feeding screw sheets at the same screw direction, namely a primary feeding screw sheet and a secondary feeding screw sheet respectively; the feeding screw sheets of the two conveying and stirring shafts are opposite in direction; the volume of screw sheets in a screw pitch of the primary feeding screw sheets is less than the volume of screw sheets in a screw pitch of the secondary feeding screw sheets; the shaft bodies of the stirring and mixing sections of the two conveying and stirring shafts are connected with large hollow stirring screw sheets through support plates; spaces between the large stirring screw sheets and the shaft bodies are internally provided with small stirring screw sheets. The automatic screw matching concrete stirring conveyer can match stably and accurately, can stir slurry repeatedly and fully, is high in efficiency, and is suitable for being popularized and applied.

Description

technical field [0001] The invention relates to concrete mixing and conveying equipment, in particular to a screw automatic proportioning concrete mixing conveyor, which can realize continuous stirring and conveying. 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, and there is ...

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 cannot achieve continuous and stable preparation of concrete, which still needs to be improved
