Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of stirring devices, and particularly relates to a concrete mixer capable of classified stirring. Background Art
[0002] Concrete is a general term for engineering composite materials that are made of aggregates bonded together by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, mixed with water in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering.
[0003] Concrete can be classified into dry-hard concrete, semi-dry-hard concrete, plastic concrete, fluid concrete, high-fluidity concrete, and flowable concrete according to the workability of the mixture. Due to the different fluidities of different concretes, the resistance to the mixing blades during the mixing process is also different. For ordinary mixers, when mixing concrete with weaker fluidity, the resistance to the mixing blades increases, and the mixing blades are more likely to be damaged. Therefore, a concrete mixer that can be mixed in different categories is proposed. Utility Model Content
[0004] The utility model aims to overcome the deficiencies in the prior art and provide a concrete mixer capable of classified mixing. By setting two mixing barrels, the two barrels are adapted to concretes of different fluidities respectively, so that the mixer can mix concretes of various fluidities more quickly and more evenly, thereby improving the mixing efficiency.

[0011] An electric valve is installed on the discharge pipe, and the electric valve is used to control the opening and closing of the discharge pipe.
[0012] The drive box is connected to the top of the barrel cover.
[0013] The sealing plate is connected to the upper inner wall of the second mixing barrel.
