Problems solved by technology
For a concrete mixer, the viscosity of the concrete will become higher and higher during the process of the concrete being mixed by the mixer; the concrete will often adhere to the inner wall of the mixer because of its high viscosity, and the stirring screw may not be able to touch the wall, making it difficult to attach When the concrete on the inner wall is mixed, even if the concrete mixed by the mixer is poured out, the concrete attached to the inner wall of the mixer will not easily fall off. Once the concrete attached to the inner wall of the mixer solidifies, it will affect the mixing of the mixer. Efficiency reduces the mixing quality, and it also causes trouble to clean the inner wall of the mixer

[0076] Specific implementation method: before the mixer is ready to mix concrete, the feed port ring shell 5 faces upwards and the feed port ring shell 5 is connected with the charging mechanism; the first spring 49 is not stretched, and the two limit plates 50 on the rotating rod 37 They are respectively located in the two limiting grooves 52 of the second support ring 36 ; the slider spring 31 is always in a compressed state, and the slider 30 is located at the end of the guide rail 27 away from the first rotating shaft 9 .
[0077] When the mixer is mixing concrete, the raw materials of the concrete enter the mixing space 55 through the charging mechanism and the material opening ring shell 5; then start the reduction motor 40, and the reduction motor 40 drives the first pulley 43 to rotate through the drive shaft 44, and the first pulley 43 passes through The belt 42 drives the second pulley 6 to rotate, and the second pulley 6 drives the first rotating shaft 9 to rotate. ...

The invention belongs to the technical field of concrete mixing and in particular relates to a concrete mixer for constructional engineering. The concrete mixer comprises a mixing mechanism, a base, ageared motor, a belt, a first belt pulley and the like, wherein a handle plate, a third loop, a rotating rod, a fixing ring plate, a clamping ring, a connecting ring, a fixing ring, a first spring, alimiting plate and a second supporting ring form a locking structure, and the barrel shell can be rotated by the locking structure; in the concrete mixing process, the opening ring shell is upward; and when discharging is needed, the barrel shell rotates to enable the opening ring shell to be downward. For the mixing mechanism, the first rotating shaft can enable screw blades to rotate around theaxis of the first rotating shaft by virtue of a series of drive; and when the first gear is fixed and the second gear rotates around the outer tooth surface, the second gear can rotate, and the second gear drives the screw blades to rotate by virtue of a series of drive; and finally, concrete in the mixing space can be mixed by the screw blades.
Description
technical field [0001] The invention belongs to the technical field of concrete mixing, in particular to a concrete mixer used in construction engineering. Background technique [0002] At present, the technology of concrete mixing is mainly used in the field of construction, and plays a very important role in the construction of buildings such as industry, agriculture, transportation, national defense, water conservancy, and municipal administration. Concrete mixer is a common machine that uses concrete mixing technology. It is a machine that mixes cement, sand and gravel aggregates and water and mixes them into concrete mixtures. For a concrete mixer, the viscosity of the concrete will become higher and higher during the process of the concrete being mixed by the mixer; the concrete will often adhere to the inner wall of the mixer because of its high viscosity, and the stirring screw may not be able to touch the wall, making it difficult to attach When the concrete on the...
