DISK-TYPE WORKING TOOL OF THE SMOOTHING MACHINE WITH VERTICAL VIBRATIONS Russian patent published in 2006 - IPC B28B11/00 

FIELD: construction industry; construction equipment.

SUBSTANCE: the invention is pertaining to the field of construction industry, in particular, to construction equipment and may be used for superfine working of the non-solidified concrete surfaces of the concrete products molded out of the hard concrete mixtures with production of the required class roughness on the face surface. The technical result of the invention is reached due to the fact, that the disk-type working tool is supplied with the disk with the undulation surface, which with the help of the planetary drive is connected to the drive unit, and the body, which is capable to rotate, is connected to the drive unit and with the main part of the disk, the effective area of which consists of the main part and two movable in the vertical direction batches of the sectors. At that the disk with the undulation surface interacts with the sectors and has a possibility of rotation and transfer through the pushers of the vertical vibrations in opposite directions to the first and the second batches of the sectors.

EFFECT: the invention ensures the superfine working of the non-solidified concrete surfaces of the concrete products molded out of the hard concrete mixtures, production of the required class roughness on the face surface.
