CONCRETE MIXER Russian patent published in 2017 - IPC B28C5/48 B01F11/00 

FIELD: construction.

SUBSTANCE: in the mixer containing resiliently fixed on the base the hollow housing assembled from sections, loading and unloading devices, the housing is made spiral in the form of hollow tunnel with multi-pass screw surface along the perimeter of spirally rolled axis 0₁-0₁ around the central straight axis 0₂-0₂ of the spiral housing provided with helical grooves inside and outside at the angle to the spiral axis 0₁-0₁ of the hollow tunnel in the form of polygonal pockets with three or more sides and assembled in the form of identical by shape and size of rings rolled from diamond shape strips, which has trapezoids, the sides of which are located on the sides of the diamond shape band and upper and lower bases of the trapezoids are arranged at sharp angle to the axis of symmetry of the strip 0₃-0₃ and are fold lines located at distances from one another, equal to the length of the pocket sides with polygonal shape with three or more sides, while the sections are mutually joined by sides of trapezoids, and the housing is rigidly fixed on the platform, under the bottom of which a vibrator is mounted.

EFFECT: improved reliability.
