DEVICE FOR PRODUCTION OF WOOD CONCRETE Russian patent published in 2020 - IPC B27N1/02 

FIELD: construction.

SUBSTANCE: invention relates to construction, in particular, to mixing equipment for production of wood concrete. Device for mixing wood particles with binder comprises housing (1) with loading (18) and unloading openings (20). Inside housing there is main drive shaft (2) with planetary reduction gear (3), in which sun gear (4) and central screw (5) are made together with drive shaft. On shafts (6) of pinions (7) mounted screws (8) of small diameter. On crown gear (9) rectangular plates (10) are rigidly fixed. On the opposite side of the planetary gearbox drum (11) is freely installed on the main drive shaft. On the drum there rigidly mounted are rectangular plates (12) entering the space between small diameter augers and rectangular plates of crown gear. Drum body is engaged via gear train (13) with main drive shaft, free end of which through coupling (14) is connected with motor-reducer (15). Between the planetary reduction gearbox and the coupling there is chain transmission (16) connecting it to screw (17) installed on the lower base of the device housing.

EFFECT: improved quality of mix mixing, simplified discharge of mix from device case.
