Embodiment Construction

[0027] refer to figure 1 , The general area or surface determined by the previous tea harvest is called the crown surface or picking working surface. If the crop is harvested mechanized by cutting at canopy level 1, both mature and immature usable parts of the plant will be harvested. In contrast, harvesters according to preferred embodiments of the present invention only harvest selected usable parts of the plants. Ideal tea growths 2 and 3 will be harvested correctly but immature tea buds and partially developed leaves 4, 5 and 6 will not be harvested.

[0028] now refer to figure 2 , where a first plant engaging device is shown, which is a conveyor belt system with a small diameter front roller 8 at the leading edge 31 for engaging tea tree leaves. If the stems and leaves of the leaves are sufficiently high above the canopy level 1, the second plant engaging means, which is a rotor 9 comprising a rotor member 10 having a resilient outer surface, deflects the stems and l...

Abstract

A harvester for harvesting plant matter including a first plant engaging means and a second plant engaging means movable relative to the first plant engaging means wherein the first plant engaging means is advanced to contact plant matter and the second plant engaging means is moved relative to the first plant engaging means to harvest plant matter by engaging the plant matter between the first and second plant engaging means.

Description

technical field [0001] The field of the invention relates to the harvesting of tea plant usable parts, and in particular to selectively harvesting only certain tea plant usable parts in a tea crop. Background technique [0002] In order to ensure high productivity, i.e. to ensure maximum potential yield and highest quality tea, the tea is generally picked selectively by hand. The aim is to pick only the tea that has grown into two leaves and one bud, and leave the immature new shoots, which if picked would reduce the total annual production of the tea tree. The work is slow and tedious and therefore the picked tea has to be held by hand. [0003] Each tea stem is pinched between the picker's thumb and forefinger and then turned over and dragged on the forefinger to snap the stem off. The usual practice is to continue this action until the hands are filled with successive plucked tea stems accumulated before being thrown into the blue basket. The tea leaves are squeezed du...
