ACTIVATOR OF HARVESTING MACHINE Russian patent published in 2015 - IPC A01D46/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry. The activator comprises two vertical finger drums mounted on opposite sides of the longitudinal-vertical plane of symmetry of the machine with the possibility of oscillation by the drive in the vertical direction and free rotation of the axis (4) of the finger drum about the vertical axis. On the axis of the finger drum, the alternating ball bearings (6) are rigidly fixed. On each of the bearings (6) a shell (8 and 11) is mounted, which covers the corresponding ball bearing with its inner spherical surface. On the shell the fingers (10) are mounted, oriented in the radial direction. In the upper part of the shell an annular recess is made, on the horizontal surface of which a compression spring (12) rests, enveloping the axis and resting with the second end to the annular recess in the lower part located above the ball bearing (6). The spring (12) is closed with a bellows (13) of elastic material.

EFFECT: implementation of an optimal algorithm of impact on fruiting branches is ensured, excluding their breaking with high efficiency of the vibration impact on berries or other fruit harvested.
