Control of vibrator hook for harvesting fruit

摘要

The control enables the conversion of angular rotation of a motor into an alternating linear movement. This movement is transmitted to the end of a pole to produce vibrations at its end. A hook (11) at the end of the pole transmits the vibrations to a branch (14) introduced into the hook internal surface (11a). The control (10) is constituted by an assembly divided into three zones. These is a neck (18) which emerges perpendicularly to the side cylindrical surface of a zone (19). Inside the cylindrical zone are crown wheels (21) with a counterweight (25) rotated by a pinion (23) which drives a control spindle transforming the angular movement into alternating linear of the hook. The cylindrical zone is extended by a flange (12) inside which are elements enabling adjustment of length toward the front or rear of the hook relative to the flange.
