Abstract

The utility model discloses a concrete mixer, which comprises an outer housing, a rotating shaft, rotating arms, shovel heads, and a motor, wherein the shovel heads are arranged at outer ends of the rotating arms; inner ends of the rotating arms are fixedly arranged on the rotating shaft; the rotating shaft is driven by the motor to rotate; the rotating shaft, the rotating arms, and the shovel heads are all positioned inside the outer housing; the motor is positioned outside the outer housing which is spherical; and an included angle between the rotating shaft and the horizontal plane is less than 90 degrees. According to the utility model, when the included angle between the rotating shaft and the horizontal plane is less than 90 degrees, that is to say, the rotary plane of the rotating arms is not horizontal, so that under double actions of the rotary shovel heads and self-gravities, mixtures are allowed to be in relative motion, therefore, the mixing is even. The concrete mixer provided by the utility model has simple structure and is low in cost, and can realize full mixing and even stirring of concretes.

Description

Concrete mixer

Technical field

The utility model relates to construction engineering technical field, relates in particular to a kind of concrete mixer.

Background technology

For some small-sized architectural engineerings, often use that some costs are lower, the comparatively easy concrete mixer of structure, the structure of this mixer mainly comprises the shell of tubular and the paddle that horizontally rotates.Deficiency low-cost, that the concrete mixer of simple structure exists usually is: because the situation that highdensity compound sinks to the bottom usually takes place the density difference of concrete mixture, thereby it is inhomogeneous that concrete is stirred; Concrete is bonded on the mixer inwall easily in addition, also causes stirring inhomogeneous easily.The concrete mixer that existing structure is comparatively complicated, the mode of utilizing shell to rotate can overcome the problems referred to above effectively, but makes that also cost significantly improves, and is unfavorable for extensive use in small-sized engineering project.

Summary of the invention

The purpose of this utility model provides a kind of concrete mixer, and is simple in structure, cost is low, and can realize concrete abundant mixing and evenly stir.

Technical solution of the present utility model is:

Concrete mixer, comprise shell, rotating shaft, spiral arm, shovel head, motor, described shovel head is arranged at the outer end of described spiral arm, the inner of described spiral arm is fixedly arranged in the described rotating shaft, described rotating shaft is rotated by described motor drives, described rotating shaft, spiral arm, shovel head all are positioned at described shell, state outside the shell under described motor is positioned at; Described shell is spherical, and the angle of described rotating shaft and horizontal plane is less than 90 °.The angle of described rotating shaft and horizontal plane is the non-level of Plane of rotation of spiral arm less than 90 °, thereby makes compound under the double action of the shovel head of described rotation and self gravitation, relative motion takes place, thereby evenly mix.

As the further improved concrete mixer of the utility model, the angle of described rotating shaft and horizontal plane is 30 °～45 °.The self gravitation effect of the Plane of rotation of spiral arm and the too little then compound of the angle of horizontal plane is not obvious, the movement locus of the too big then compound of the Plane of rotation of spiral arm and the angle of horizontal plane is too simple, it is the gyration of simple vertical direction, and need power consumption excessive, it is excessive that spiral arm bears active force, and the equipment energy consumption high life is short; And the angle of rotating shaft and horizontal plane is when being 30 °～45 °, compound by the shovel head of described rotation kick up the back under the self gravitation effect to level two lateral movements of shell, after arriving the sidewall of described shell, move in bottom to described shell under the self gravitation effect again, thereby realize the even stirring of compound.

As the further improved concrete mixer of the utility model, be provided with elastomer between described spiral arm and the described shovel head.The concrete scaling that can be under described elastomeric thrust the described outer casing inner wall of concrete mixer be bondd, thus realize fully mixing and evenly stirring.

As the further improved concrete mixer of the utility model, the outer end of described spiral arm is provided with groove, and described shovel head is provided with projection, described projection can with described groove fit, described elastomer is between described projection and described bottom portion of groove.

As the further improved concrete mixer of the utility model, fixedly connected with shovel with described spiral arm respectively in described elastomer two ends.The extended length of described elastomer nature is during less than described depth of groove, fixedly connectedly can prevent that described shovel head from coming off.

Concrete mixer provided by the utility model, simple in structure, cost is low, and can realize concrete abundant mixing and evenly stir.
