Concrete mixer used for municipal construction engineering and based on spiral sheets

Abstract

The invention belongs to the technical field of mixers, and particularly relates to a concrete mixer used for municipal construction engineering and based on spiral sheets. The concrete mixer comprises a mixing shell, an adjustment mechanism, spiral mixing sheets, an arc-shaped scraping sheet, a thread rod and a thread sleeve. When the mixer designed by the invention is used, before use, a fillingport formed in the mixing shell is enabled to be upward through the adjustment mechanism; then the raw materials of concrete are filled into the mixing shell through the filling port in the mixing shell through a filling mechanism; according to the mixer designed by the invention, the concrete adhered onto the inner circle surface of the mixing shell can be cleared through the designed arc-shapedscraping sheet; influence on normal use for the concrete due to inadequate mixing for the concrete adhered onto the inner circle surface of the mixing shell, is prevented; and meanwhile, if the inadequately-mixed concrete is adhered onto the inner circle surface of the mixing shell, during unloading for the concrete, the inadequately-mixed concrete adhered onto the inner circle surface of the mixing shell falls into the adequately-mixed concrete to influence the overall quality of the concrete.

Description

technical field [0001] The invention belongs to the technical field of mixers, and in particular relates to a concrete mixer based on spiral blades used in municipal construction projects. Background technique [0002] Concrete mixing device is a machine that mixes cement, sand and gravel aggregate and water and mixes it into concrete mixture. With the rapid development of the construction industry, concrete mixing devices are becoming more and more diversified, but the traditional concrete mixer The inner surface of the mixing shell often adheres to the unmixed concrete; when the concrete is unloaded, the unmixed concrete sticking to the inner surface of the mixing shell will fall into the fully mixed concrete, which is harmful to the concrete. Therefore, it is very necessary to design a mixer that can clean the insufficiently mixed concrete adhered to the inner surface of the mixing shell during the mixing process. [0003] The present invention designs a concrete mixer b...

[0002] Concrete mixing device is a machine that mixes cement, sand and gravel aggregate and water and mixes it into concrete mixture. With the rapid development of the construction industry, concrete mixing devices are becoming more and more diversified, but the traditional concrete mixer The inner circular surface of the medium mixing shell often adheres to the unmixed concrete; when unloading the concrete, the unmixed concrete stuck to the inner circular surface of the mixing shell will fall into the fully mixed concrete. Therefore, it is very necessary to design a mixer that can clean the insufficiently mixed concrete adhered to the inner surface of the mixing shell during the mixing process
