Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and more specifically to a construction concrete mixing device capable of reducing dust. Background Art

[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementitious materials, granular aggregate (also called aggregate), water and admixtures and additives added when necessary in a certain proportion, which are evenly stirred, compacted into a dense shape, and cured and hardened. Ready-mixed concrete refers to a concrete mixture of cement, aggregate, water and admixtures and mineral admixtures added as needed in a certain proportion, which is sold after being measured and mixed at a mixing station and transported to the place of use within a specified time by a transport vehicle.

[0003] Since concrete is mainly composed of cementitious materials, water, sand, gravel, and chemical admixtures and mineral admixtures when necessary, they are mixed in appropriate proportions. There are materials of different sizes that need to be mixed, and the stirring blades of existing concrete mixing devices are mostly fixed in the stirring device, which is not uniform during stirring and the mixing quality of concrete is reduced.

[0004] After searching, the Chinese patent with publication number CN218053267U discloses a concrete mixing device for construction engineering. Through the mutual cooperation between the motor, worm, first stirring rod, transmission box, rotating rod, worm gear, second stirring rod and other mechanisms, more sufficient mixing of concrete can be achieved.

[0005] When the above-mentioned concrete mixing device for construction projects is actually used, there will still be a certain amount of concrete residue inside after mixing and stirring is completed, which may accelerate the wear and corrosion of the equipment. Long-term accumulation will cause the performance of the equipment to decline. At the same time, it may cause concrete from different batches and different proportions to be mixed together, which may lead to unstable product quality. Utility Model Content
