Detailed Description
The technical solutions in the novel embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the novel embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the novel embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the novel concept, are within the scope of the novel protection of the present invention.
Terms used herein, including technical and scientific terms, have the same meaning as terms commonly understood by one of ordinary skill in the art, unless otherwise defined. It will be understood that terms defined in commonly used dictionaries have meanings that are consistent with their meanings in the prior art.
Referring to fig. 1 to 2, a concrete admixture anti-settling device for building construction includes an outer cylinder 1; the outer cylinder body 1 is provided with a weighing hopper, and the inner cylinder body 2 is arranged in the outer cylinder body 1; the inner cylinder body 2 is rotationally connected with the outer cylinder body 1 and vertically moves along the outer cylinder body; a main shaft 3 is arranged in the outer cylinder 1; the main shaft 3 is provided with a stirring disc 4; the side part of the stirring disc 4 is connected with the inner side of the inner cylinder body 1; the bottom of the inner cylinder body 2 is provided with a plurality of through holes 2.1.
