Abstract

Harvesting apparatus for harvesting fruit, berries, and similar produce, including at least on vibratable shaker head assembly positioned to each side of a central longitudinal axis of the apparatus so that the shaker head assemblies are not transversely aligned but are in staggered relationship with respect to each other to each side of the longitudinal horizontal axis. Each shaker head assembly has a plurality of harvesting fingers which are subjected to rotational and vibrational movement by the shaker heads and, in use of the apparatus, the harvesting fingers come into contact and penetrate produce bearing plants or bushes and remain substantially continuously in contact with the plants and bushes as the apparatus moves through or over the plants or bushes, thereby subjecting the plants or bushes to continuous vibrations and shaking to cause fruit, berries or like produce to be dislodged therefrom.

Dependent claims

Harvesting apparatus, comprising:

(a) a main frame movable relative to the ground;
(b) power means mounted on said main frame to provide power for the relative movement between said main frame and the ground;
(c) at least one shaker head assembly located to each side of a longitudinal horizontal axis extending centrally through said main frame, each shaker head assembly having an output and a vertical axis of rotation, the or each shaker head assembly to one side of said longitudinal axis being located forwardly of the corresponding shaker head assembly on the other side of said longitudinal axis such that said shaker head assemblies are positioned in a staggered relationship along said main frame;
(d) a shaft attached to the output of each said shaker head assembly and
(e) at least one set of radially spaced harvesting finger means attached to each said shaft, said harvesting finger means, in use, coming in contact with and penetrating produce bearing plants or bushes and vibrating and shaking said plants or bushes to cause fruit, berries or the like produce to be dislodged therefrom, said harvesting finger means remaining substantially continuously in contact with said plants or bushes as said main frame moves through or over said plants or bushes, whereby said plants or bushes are subjected to continuous vibrations and shaking during said contact with said harvesting finger means.

A harvesting apparatus, comprising:

(a) a main frame movable relative to the ground;
(b) power means mounted on said main frame to provide power for the relative movement between said main frame and the ground;
(c) a pair of vibrational shaker head assemblies mounted to each side of a longitudinal horizontal axis extending centrally through said main frame, each of the assemblies having an input and an output with a respective associated input and output member;
(d) a prime mover;
(e) means for converting rotary motion applied to each input member into a torsional vibration superimposed on the associated output member, the output members being mounted so as to enable a rotary motion to be superimposed thereon;
(f) power transfer means for transmitting high speed rotational movement to the imput members of each pair of shaker head assemblies;
(g) means coupling together the output members of each pair of shaker head assemblies whereby the rotational and vibrational movement of one output member of the pair is the same as the other;
(h) at least one set of radially spaced harvesting finger means positioned in operative connection with each output member;
said shaker head assemblies being so positioned to each side of said longitudinal horizontal axis that they are not transversely aligned but are in a staggered relationship to each side of said longitudinal horizontal axis, said harvesting finger means in use, coming in contact with and penetrating produce bearing plants or bushes and vibrating and shaking said plants or bushes to cause fruit, berries or the like produce to be dislodged therefrom, said harvesting finger means remaining substantially continuously in contact, with said plants or bushes as said main frame moves through or over said plants or bushes, whereby said plants or bushes are subjected to continuous vibrations and shaking during said contact with said harvesting finger means.
