Concrete stirring device for construction site

Abstract

The invention discloses a concrete mixing device for a construction site, which comprises a machine case. The inner chamber of the machine case is symmetrically provided with partitions, and a plurality of through holes are arranged on the partition board. The partition board divides the inner chamber of the machine case into a mixing chamber and two The inner wall of the clamping chamber is provided with a number of top sleeves corresponding to the through holes. The top sleeve is provided with a top hole. The stirring chamber is equipped with a main stirring rod. The top of the main stirring rod passes through the chassis and is fixedly connected. On the motor shaft of the main motor, a number of rotating rollers are evenly arranged on the main stirring rod. Track grooves are arranged on the rotating rollers, and rollers are arranged in the track grooves. The auxiliary stirring rods are fixedly connected to the rollers. There are several stirring blades, and the bottom of the cabinet is evenly provided with several legs; the main motor of the present invention drives the main stirring rod to rotate, and then drives the rotating roller to rotate, and the rotating roller drives the auxiliary stirring rod to stir, so that the stirring blades stir irregularly Materials, improve the mixing efficiency of materials, and ensure that sand or stones are completely 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
