DRUM MIXER Russian patent published in 2015 - IPC B01F9/02 

FIELD: machine building.

SUBSTANCE: drum mixer contains gear motor, driving crank, drum and stand. Meanwhile the mixer contains spatial bar, main connecting rod and main connecting rod gear motor. And the drum and the spatial bar are connected articulately and are located in series between the driving crank and the main connecting rod, each of them is connected with its gear motor. Axes of holes of the driving crank and spatial bar are designed crossed spatially at identical angles and with identical shortest distances between these axes. The axes of holes of the drum and the main connecting rod are designed crossed under at identical right angles and with identical shortest distances between axes. Meanwhile the shaft of the driving crank is connected directly to the gear motor, and the hollow shaft main of the connecting rod is connected to the gear motor through the pair of gear wheels. And the shaft of the driving crank is mounted on the hollow shaft of the main connecting rod, installed on the stand, with a possibility of rotation with reference to each other, putting in complex planetary and spatial motion with variable speeds and accelerations of the drum.

EFFECT: improved quality of mixing.
