Concrete stirring device for construction site

Abstract

The invention discloses a concrete stirring device for a construction site, which comprises a case. The inner cavity of the case is symmetrically provided with baffles left and right, a plurality of through holes are arranged in the baffles, the baffles divide the inner cavity of the case into a stirring cavity and two clamping cavities, the inner wall on one side of each clamping cavity is provided with a plurality of pushing covers corresponding to the through holes, pushing holes are arranged in the pushing covers, a main stirring rod is arranged in the stirring cavity, the top end of the main stirring rod penetrates through the case and is fixedly connected to the motor shaft of a main motor, the main stirring rod is uniformly provided with a plurality of rollers, track grooves are arranged in the rollers, idler wheels are arranged in the track grooves, the idler wheels are fixedly connected to secondary stirring rods, the secondary stirring rods are uniformly provided with a plurality of stirring blades, and the bottom end of the case is uniformly provided with a plurality of support legs. The main motor of the concrete stirring device drives the main stirring rod to rotate and further drives the rollers to rotate, the rollers drive the secondary stirring rods to move and stir, such that the stirring blades stir materials irregularly, the stirring efficiency of the materials is improved, and sand, stones, and the like are enabled to be totally stirred.

Description

technical field [0001] The invention relates to the technical field of concrete mixing, in particular to a concrete mixing device for a construction site. Background technique [0002] Concrete, referred to as "concrete" for short: refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. [0003] The mixing of concrete usually requires the use of concrete mixing equipment. At present, the domestic large-scale concrete mixing equipment first directly mixes sand, gravel, water, cement and additives according to the proportion, and then mixes them through the mixing equipment at one time. However, ...

AI Technical Summary

Problems solved by technology

At present, the domestic large-scale concrete mixing equipment first directly mixes sand, gravel, water, cement and additives according to the proportion, and then mixes them through the mixing equipment at one time. However, the internal mixing mechanism of this equipment is Rotate evenly, so that the materials are stirred regularly, resulting in a long mixing period of the materials, and the sand or stones are not stirred or are not stirred evenly, which leads to poor quality of the produced concrete and cannot achieve satisfactory results, and large concrete The mixing equipment is tall and difficult to feed materials, which brings great troubles to the workers' operation
