摘要

This device for harvest of fruit or racks, in particular grapes, for cultures in the lines of the type constituted by a vehicle on the chassis of which are mounted to rotate the drums "hedgehogs" of fingers or flails penetrating the vegetation and unhooking the fruit. The drums are bunk subdivided in coaxial elements 16, 16a.. Each comprising a hub 26 cleat on the vertical drive shaft 7 and forming a variable angle a with the latter, and the sleeves 16 mounted for free rotation on these hubs and also inclined axes of the same angle a, these hubs carrying the fingers 15 and a support 38 of the vibrating masses entrained in terms of rotation 19. This device gives rise to a vibration of the fingers 15 adjustable by the speed of rotation of the shaft 7, the variation of the angle a and the clearance of the weights, vibration obtained by means of a vertical component and a horizontal component adjustable independently of one another.
