MACHINE FOR HARVESTING FRUIT AND BERRIES AND THE LIKE FROM FRUIT TREES AND BUSHES PLANTED IN A ROW, AND SHAKER ROD FOR A MACHINE OF THIS KIND

摘要

In this harvesting machine using shaker members in the form of rods to shake the fruit-bearing bushes and harvest the fruit, each shaker rod has an elongate base part (11a) which has, in use, a required flexibility characteristic for the rod (11) in a horizontal plane and which has an oblong cross-section whose height is greater than its width, said cross-section having two main geometrical axes which are respectively horizontal and vertical and dimensions of height (a) and width (b) such that its moment of area about the horizontal main axis is significantly greater than its moment of area about the vertical main axis and its height (a) is less than a predefined value. The base part (11a) forms a core for the rod (11), which can further include a wear part (32) which covers the core (11a) and which is made of a material and has a thickness such that the rod has flexibility characteristics in the horizontal and vertical planes that are practically unchanged relative to those of the core, even after substantial wear of the wear part (32).
