Concrete mixing drum blade and concrete mixing transport vehicle

Abstract

The invention discloses a concrete mixing drum blade and a concrete mixing transport vehicle, wherein the bottom ends of helical blades are fixedly connected with the inner wall of a drum body; each helical blade comprises a blade heightening section which is arranged at the front section of a rear cone; the blade heights of the blade heightening sections are greater than those of the helical blades respectively arranged at the two sides of the blade heightening sections; the top of a blade arranged on each blade heightening section is provided with an additional blade; each additional blade has a tube-shaped structure. The concrete mixing drum blade and the concrete mixing transport vehicle are obvious in material leakage prevention effect, and are capable of effectively realizing material sealing; the concrete mixing drum blade and the concrete mixing transport vehicle are low in cost, a tooling does not need to be additionally arranged, and the geometric volume, the angle of inclination and the like of the drum body do not need to be increased, so that the operation is simple, and the technological process is not changed.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a concrete mixing drum blade and a concrete mixing transport vehicle. Background technique [0002] At present, various manufacturers have launched a large number of mixer trucks one after another. The problem of material leakage from mixer trucks has become a difficult problem in the industry. The industry usually adopts the following two methods to solve this problem. One is to increase the geometric volume of the mixer drum; the other is to increase Mixing drum angle. Under the limitation of ultra-high conditions, the effects of the two methods are not obvious and the bearing moment of the reducer is relatively large. In contrast, increasing the geometric volume of the mixing drum can solve the problem of mixing volume under certain conditions, but the weight of the upper body increases significantly and the cost is higher. The above methods can properly allevi...

AI Technical Summary

Problems solved by technology

The above methods can properly alleviate the problem of material leakage when the mixer truck climbs, and are suitable for situations where the slope is small, the distance is short, and the overflow is not serious.

②Oil consumption increases significantly, and the use cost is higher
