Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, in particular to a water conservancy engineering construction device. Background Art

[0002] A water conservancy project refers to a project built to eliminate water disasters and develop and utilize water resources. Only by building water conservancy projects can we control the flow of water, prevent flood disasters, and regulate and distribute water to meet the people's needs for water resources for life and production.

[0003] Water conservancy projects cannot be separated from concrete during the construction process. When concrete is used, it needs to be mixed with water to meet the conditions for use. Therefore, concrete mixing equipment is a very important construction device for water conservancy projects. Concrete mixer is a machine that mixes cement, sand and gravel aggregates and water into concrete mixture.

[0004] Some water conservancy engineering devices currently on the market:

[0005] (1) During the mixing process, since concrete is mixed with multiple raw materials, and the proportions and densities of the raw materials are different, the mixer cannot mix the multiple raw materials well, reducing the mixing efficiency;

[0006] (2) When the mixer is not in use, the existing mixer mixing tank is not convenient to disassemble and clean. A small amount of concrete will remain in the mixing tank. If it is not cleaned for a long time, it will solidify inside the mixing tank, reducing the space in the mixing tank and reducing the mixing efficiency.
