Problems solved by technology

However, setting the discharge funnel will increase the volume of the cylinder, and the mixer must be suspended from the ground for erection, which is not only inconvenient to carry, but also the discharge funnel occupies a relatively large area, which will greatly increase the weight of the whole machine

Embodiment 1

[0021] Such as figure 1 Shown: a stirring device for a concrete mixer, including a cylinder 1 and a stirring device disposed in the cylinder 1; the stirring device includes two stirring shafts 2, and the two stirring shafts are equipped with stirring blades 3 and the helical structure 4, the stirring blade 2 and the helical structure 4 are respectively arranged on both sides of the stirring shaft.

[0022] The above scheme has the following advantages: by setting two stirring structures of stirring blade and spiral structure on one stirring shaft, both the stirring blade and the spiral can play a stirring role, especially the stirring blade plays the main stirring role, and the spiral structure can stir The final formed uniform concrete is unscrewed, so that there is no need to set a discharge funnel at the bottom of the cylinder, thereby reducing the volume and overall weight of the cylinder and making it easy to carry. It can be said that this embodiment can not only achiev...

Embodiment 2

[0031] Such as figure 2 Shown: the difference with embodiment 1 is that the structure of the two stirring shafts is: the first half of one stirring shaft 2 is provided with stirring blade 3, and the second half is provided with helical structure 4; the first half of the other stirring shaft is provided with Spiral structure 4, the second half is provided with stirring blade 3. And the helical structure is a complete helix. When the stirring blade on one stirring shaft is stirring at the front side, the stirring blade on the other stirring shaft is stirring at the rear side to improve the uniformity of the concrete; when the concrete is output, the spiral structure in front of one stirring shaft and the other The helical structure on the rear side of the mixing shaft works together to quickly spin out the concrete. This structure can greatly improve the mixing efficiency and unscrewing speed of concrete.

[0032] In summary, the mixing blade and the helical structure of the...

Abstract

A mixing device used for a concrete mixer comprises a barrel body and a mixing device body arranged in the barrel body. The mixing device body comprises two mixing shafts. Mixing blades and a spiral structure are arranged each mixing shaft, and the corresponding mixing blades and the corresponding spiral structure are arranged on the two sides of each mixing shaft correspondingly. According to themixing device, through the combined action of the mixing blades and the spiral structures, the mixing efficiency can be improved, uniformity of concrete can be high, the concrete can be rapidly output, and the screw-out speed is greatly increased; and the concrete can be directly output from a discharging port in the side face of the barrel body, a discharging funnel does not need to be additionally arranged at the bottom of the barrel body, the structure is more compact, the weight of the whole machine is greatly decreased, and carrying is convenient.

Description

technical field [0001] The invention relates to a concrete mixer, in particular to a mixing device for a concrete mixer. Background technique [0002] A concrete mixer is a machine that mixes cement, sand and gravel aggregates and water and mixes them into concrete mixtures. The concrete is stirred by the mixing blades to obtain concrete with good uniformity, and then it is transported to the hopper truck through the discharge funnel at the lower part of the cylinder to transport the concrete to the construction site. The stirring device of the existing mixer usually includes two stirring shafts, and stirring blades are arranged on the two stirring shafts, so as to improve the mixing efficiency of concrete and improve the uniformity. The stirred concrete is directly output through the lower discharge hopper. However, setting the discharge funnel will increase the volume of the cylinder, and the mixer must be suspended from the ground for erection, which is not only inconve...
