Building concrete configuration equipment

Technical Field

The invention belongs to the field of building construction, and particularly relates to building concrete configuration equipment.

Background

Concrete mixing proportion and mixing operation are important work in concrete engineering, and directly influence the setting strength and construction cost of concrete. The conventional mixing method of concrete is to mix cement: water: sand 1: x: y sets up, and water, grit and stone are the use amount and can select corresponding use amount according to the use occasion.

When the mixing of cement, water and grit is stirred, generally the manual work is whole with cement, water and grit and is placed subaerial, then adopts the shovel to turn over the concrete, and the concrete adheres to subaerial easily, and then can lead to the waste of partial concrete, when adopting the manpower to turn over simultaneously and stir, relatively wastes time and energy, still can lead to the mixing of cement, water and grit inhomogeneous.

Disclosure of Invention

The invention aims to provide building concrete configuration equipment to solve the problem that concrete is easy to adhere to the ground, and further, partial concrete is wasted.

In order to achieve the above object, the basic scheme of the invention is as follows: building concrete configuration equipment includes the agitator and installs the stirring unit in the agitator, still includes feed unit, and feed unit includes the portion of intaking that can add water in the agitator and a plurality of feed portion that can add cement or grit in the agitator, and portion of intaking and feed portion all fix on the agitator, and portion of intaking and feed portion all communicate with the agitator.

The principle and advantages of the basic scheme are as follows: before mixing of water, cement and sand, the cement and the sand can enter the stirring barrel through the feeding parts, meanwhile, the water can enter the stirring barrel through the water inlet parts, and at the moment, the water, the cement and the sand can be stirred and mixed in the stirring barrel through the stirring units in the stirring barrel, so that the waste amount of concrete can be effectively reduced; meanwhile, the water, the cement and the sand can be fully stirred and mixed, manual stirring is not needed, and time and labor are saved.

Simultaneously when cement and grit enter into the agitator through the feed portion in, cement and grit are also difficult for scattering from the agitator, can realize the make full use of cement and grit, the further waste volume that reduces cement and grit.

Further, a plurality of feed portions evenly set up on the vertical lateral wall of agitator, and feed portion all is located the upper end of agitator.
