It will be apparent to those skilled in the art that and use device recited above to have a lot of substantial advantage, these advantages comprise:

No longer need any passage between (I) tea clump band, so the tea clump can connect the body growth, form the tea clump canopy that mutually intersects, not lead to passage or the opening on ground, thereby can control weed growth and reduce the use of herbicide agent.

(II) machine is supported by the tea clump, no matter so that the arrangement of its tea clump or position pick tea-leaves on can both be in any direction.

(III) picked tea-leaves in the tea place with this device and is not subjected to the restriction of gutter direction below the tea clump or quantity.

(IV) this device is the cutting height of the new long tender tealeaves of control very accurately, and plucks to realize automatic adjusting by not in contact with the ground from tea clump top.

(V) this device can be avoided the ground pressuring action, because it is by the supporting of tea clump, and weight fraction is dispersed on the larger area.

Because this device is by tea clump top-supported, gathering can raise along with the growth of tea clump and integral shroud highly naturally (VI), therefore can improve the quality of tealeaves.

(VII) this device can improve the output of tea clump, because it can adopt down long tea stalk.

(VIII) this device need not just can be picked tea-leaves with maintenance suitable height overhead in beta pruning.

Just because be not by ground supporting, this device can be picked tea-leaves on precipitous slope (IX). At this kind occasion (seeing Figure 21), the top of tea clump will cut flat usually, in order to can support machine thereon.

Existing mechanical picking device can only be on the level land or wavy ground use. If cover belt or the wheeled machinery operation on precipitous slope of picking tea-leaves, may skid because of common wet condition, and slip into the tea clump and then damage the tea clump. In the plantation of the precipitous country of landform, the tea clump is become the terrace type plantation, so that the use of hand-held formula tea picking machine difficulty and dangerous very, because operator stands in the bottom of terraced fields, another operator stands in the top. Another difficult problem of precipitous landform is the soil erosion. In order to address this problem, the gutter of digging level surrounded by mountains, and communicate with vertically downward ditch, so that water is drained. Employing is hand-held wheeled or cover belt machinery, and it is difficult crossing these ditches. In the present invention, mechanical device is only advanced by the supporting of tea clump and along the contour on slope, like this, basically keep horizontal state along isocontour one top of arranging (or two rows) tea clump, thereby machine also keeps horizontal state. In addition, the top surface of tea clump also can be consistent with the landform on slope, and machine is along the slope upstream or downstream.

Variation of being done within the scope of the appended claims or improvement also are predictable.For example, except can be along collecting chute 64 upwards blows, can also be air-breathing with being contained in the appropriate device of collecting the chute upper end.
