Embodiment Construction

[0042] As mentioned above, it is desirable to provide a tea harvester that can selectively harvest the largest area of ​​tea shoots without damaging immature tea shoots and preserve the leaves.

[0043] device

[0044] refer to Figure 1 to Figure 4 as well as Figure 8 The tea harvester 1 comprises a conveyor belt assembly 2 , a second plant engaging member being a rotor assembly 4 and a stem engaging member being a crusher rod assembly 3 . The conveyor belt assembly 2 comprises a conveyor belt 5 made of elastic material constituting the first plant engaging member, a front belt support roller 6 at the leading edge of the conveyor belt assembly 2, a rear belt support roller 7, a conveyor cross tube support Part 8, supporting part 9 and fixing bolt 10. The conveyor belt 5 is mounted on a front belt support drum 6 and a rear belt support drum 7 , which are supported by support members 9 linked to conveyor cross tube supports 8 . The support part 9 is attached to the conveyo...

Abstract

Apparatus for selectively harvesting plant material, particularly the leaves and bud of a plant having a stem, such as a tea plant, is provided. The apparatus includes a conveyor belt (5), plant engaging members (20) movable relative to the conveyor belt (5) to trap the plant matter between the conveyor belt (5) and the plant engaging members (20) at a first level, and a stem engaging member (11) arranged to contact a stem of the plant at a predetermined second level, lower than the first, wherein when the stem of trapped plant material extending above the predetermined second level is broken by the stem engaging member (11) to harvest the trapped plant material. In one embodiment, the stem engaging member is a breaker bar (11). In an alternative embodiment, the stem engaging member is a cable, wire or cord maintained in tension at the predetermined second level.

Description

technical field [0001] The present invention relates to plant harvesting devices, and more particularly to devices for harvesting selected plant matter of tea crops. Background technique [0002] The invention will be described herein with specific reference to the harvesting of tea, however, obviously the invention can also be used for harvesting other plant crops and the scope of the invention should therefore not be limited to harvesting tea. [0003] Machines have been devised to mechanically harvest leaves regardless of growth stage by mechanically cutting off all tea stems at a set height. This practice reduces overall tea bush productivity, but the practice is less labor intensive. It would be desirable to provide machinery for selectively harvesting only those shoots of the optimum size and growth stage ensuring highest tea quality and maximum bush productivity, while requiring less labor than manual harvesting. [0004] Williames Tea Pty Ltd has previously develop...
