The hydraulic vibrator is used, which is used as an autonomous unit of drive of working bodies of fruit harvesting shakers. The principle of operation of this vibrator is to create a working cylinder of the executive hydraulic cylinder pulsating pressure. Constructive features of a hydraulic vibrator allow to achieve high operational reliability, small dimensions and provide normal operation without a safety valve in the hydraulic system.

On its basis, a fruit shaker was created for the processing of trees in the continuous motion of fruit harvesting machines along the length of a row. The hydropulse drive of the vibrator carries the drive from the base machine, which is mounted on the fruit and harvesting unit.
