Building concrete mixer

Abstract

The invention belongs to the technical field of concrete mixing, and particularly relates to a building concrete mixer. The building concrete mixer comprises a mixing mechanism, a base, a speed reduction motor, a belt, a first belt wheel and the like. A lock structure is composed of a handle plate, a third ring sleeve, a rotation rod, a fixing ring disc, a clamping ring, a connecting ring, a fixing ring, a first spring, a limiting plate and a second supporting ring sleeve, and the lock structure can achieve barrel shell rotation. In the concrete mixing process, a material port ring shell is arranged upwards. When unloading is needed, a barrel shell rotates, and the material port ring shell is arranged downwards. For the mixing mechanism, after a first rotation shaft is subjected to a series of transmission, a spiral sheet can be made to revolve around the axis of the first rotation shaft; when a first gear is fixed and a second gear rotates around the outer gear face of the first gear,the second gear can rotate by itself, and accordingly the spiral sheet is driven to rotate by itself after the second gear is subjected to a series of transmission; and finally, the spiral sheet canmix concrete in the mixing space.

Description

technical field [0001] The invention belongs to the technical field of concrete mixing, in particular to a concrete mixer for construction. Background technique [0002] At present, the technology of concrete mixing is mainly used in the field of construction, and plays a very important role in the construction of buildings such as industry, agriculture, transportation, national defense, water conservancy, and municipal administration. Concrete mixer is a common machine that uses concrete mixing technology. It is a machine that mixes cement, sand and gravel aggregates and water and mixes them into concrete mixtures. For a concrete mixer, the viscosity of the concrete will become higher and higher during the process of the concrete being mixed by the mixer; the concrete will often adhere to the inner wall of the mixer because of its high viscosity, and the stirring screw may not be able to touch the wall, making it difficult to attach When the concrete on the inner wall is m...

AI Technical Summary

Problems solved by technology

For a concrete mixer, the viscosity of the concrete will become higher and higher during the process of the concrete being mixed by the mixer; the concrete will often adhere to the inner wall of the mixer because of its high viscosity, and the stirring screw may not be able to touch the wall, making it difficult to attach When the concrete on the inner wall is mixed, even if the concrete mixed by the mixer is poured out, the concrete attached to the inner wall of the mixer will not easily fall off. Once the concrete attached to the inner wall of the mixer solidifies, it will affect the mixing of the mixer. Efficiency reduces the mixing quality, and it also causes trouble to clean the inner wall of the mixer
