CONCRETE MIXER OF CONTINUOUS ACTION Russian patent published in 2012 - IPC B28C5/20 

FIELD: construction.

SUBSTANCE: in a concrete mixer of continuous action comprising a casing arranged on a stand by means of a frame with pneumatic cylinders introduced into a device, and the casing is equipped with a drive, the casing is mounted from sections different in their shape and dimensions increasing from loading to unloading, which are joined in series and in turns, at the same time the first section is arranged from two subsections, one of which is mounted from two large scalene triangles joined by their bases with lateral sides of a large equilateral trapezoid, and the second subsection is mounted from a small equilateral trapezoid, to lateral sides of which two small equilateral triangles are connected by their small lateral sides, bases of which are equal to large lateral sides of triangles of the first subsection, by which the subsections are connected to each other, besides, upper bases of trapezoids of two subsections are equal to each other and are equal to small lateral sides of triangles of the first subsection with formation of a small inlet hole of the section, and lower bases of trapezoids are equal to each other and are equal to large lateral sides of triangles of the second subsection with formation of a large output hole of the section, to which the second section is connected, arranged in the form of a right triangular prism formed by a section of a cube along a diagonal, at the same time along the entire length of the casing there is a cylindrical spring mounted, which is equipped with a device to vary a pitch of turns by means of their tension or compression and is equipped with a pipeline with a fixed conical screw nozzle for supply of hardening water for a distance L.

EFFECT: expansion of functional capabilities.
