Description

A kind of dark brownish green picking method of hoisting type and picking head
Technical field
The present invention relates to agricultural machinery technological field, be specifically related to the dark brownish green picking method of a kind of hoisting type and picking head.
Background technology
At present, picked by hand remains dark brownish green general picking method, is generally completed by several workman of picking tea-leaves, be divided into select, break-off type plucks and the step such as collection, though picked by hand can ensure dark brownish green quality, there is the drawbacks such as picking efficiency is low, labour intensity is large.Because picking efficiency is low, often cause high-quality tea leaves not pluck in time and aging, have a strong impact on the income of tea grower and tea enterprise.
Seek the concern that efficient high-quality tea leaves mechanical picking method and technology are subject to countries in the world all the time.At present, dark brownish green mechanical picking know-why is substantially all adopt the mode of cutting to carry out, in existing product, common are three kinds of modes such as reciprocating cutting, spiral hobbing cutter cutting, the cutting of horizontal rotary rotor.The application that tea machinery is plucked mainly concentrates on ordinary populace tea picking field, and reciprocating cutting, double or single picking machine use wider.Therefore the dark brownish green picking machine of reciprocating cutting has that picking efficiency is high, to save labour, plucking cycle short and ensure the advantages such as leaf quality, but also there is the shortcomings such as broken leaf rate is high, large, the dark brownish green old stalk Lao Ye of tea tree damage is many, for the harvesting of low and middle-grade tealeaves.
In addition, the dark brownish green Softening of cutting type adopts sharp blade cuts to realize dark brownish green harvesting, though can significantly promote dark brownish green picking efficiency, owing to cutting dark brownish green by sharp blade, make the rapid blackening of otch dark brownish green after cutting, have a strong impact on into the color and luster product phase of sampling tea.
Summary of the invention
In order to solve the problems of the technologies described above, the present invention aim to provide a kind of picking efficiency high, do not destroy dark brownish green with tea tree, the dark brownish green picking method of hoisting type that can ensure into quality of sampling tea and picking head.
The present invention is achieved by the following technical solution:
The dark brownish green picking method of a kind of hoisting type, dark brownish green harvesting is completed by the picking head that some groups rotate, every two picking head are one group, reversely rotate with group picking head, rotate and make the gap between picking head be "ON" and " closing " state, time between picking head in "On" state, green grass or young crops to be picked tea-leaves is imported between picking head, along with the reverse rotation of adjacent two picking head, gap between picking head is from "ON" to " closing ", the seamed edge of picking head is clamped dark brownish green stem and is upwards lifted, and the most dark brownish greenly breaks from stem, realizes carrying adopting.
Described blue or green importing of waiting to pick tea-leaves is dredged plate by dentation and has been come.
A kind of picking head realizing the dark brownish green picking method of above-mentioned hoisting type, this picking head is cylindrical or conical, its front portion is introduction segment, the section of adopting is put forward for clamping in middle part, rear portion is transmission segment, the cross section that the section of adopting is put forward in described clamping is symmetrical multiple tooth form, and between cog teeth groove is straight trough or helicla flute, and the cross section of each tooth is rectangle or wedge shape.
The end land width size that each tooth in the section of adopting is carried in described clamping is less than 3mm, and seamed edge relief angle α is less than 60 °.
When every two adjacent picking head are in " closing " state, seamed edge spacing is less than 1mm.
The quantity that tooth in the section of adopting is carried in described clamping is 2 ~ 4.
Described introduction segment is rectangle or taper.
Described transmission segment is gear.
Described transmission segment is gear.
The invention has the beneficial effects as follows:
Compared with prior art, the dark brownish green picking method of hoisting type provided by the invention, it can replace traditional picked by hand, there is the advantages such as speed is fast, efficiency is high, safe ready, and its adopt rotation, clamp, promote, the mode of pulling apart is dark brownish green to pluck, pluck compared to traditional cutting type, this method pluck dark brownish green can not the rapidly blackening because sharp cutter cutting, ensure that into the color and luster product phase of sampling tea; And leave gap between picking head, there will not be the phenomenons such as cutting is incomplete, prevent the appearance of broken leaf, effectively can ensure dark brownish green integrality, make it have good outward appearance; The method also can not damage tea tree simultaneously, and the germination rate of tea tree is guaranteed, and then output is unaffected.

Embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is described further, but described in required protection domain is not limited to;
The dark brownish green picking method of hoisting type provided by the invention: dark brownish green harvesting is made up of the picking head that some groups rotate, the direction of rotation often organizing two picking head is contrary, rotate and make the gap between picking head be "ON" and " closing " state, time between picking head in "On" state, green grass or young crops to be picked tea-leaves is imported between picking head, and the gap between picking head is from "ON" to " closing ", and the seamed edge of picking head is clamped dark brownish green stem and upwards lifts, the most dark brownish greenly to break from stem, realize carrying adopting.
Described blue or green importing of waiting to pick tea-leaves is dredged plate by dentation and has been come, dredge plate and be positioned at picking head top, dredging plate is dentation, the corresponding picking head opened and closed positions of between cog part, toothed portion correspondence is plucked between head group, this dentation is dredged plate and by green grass or young crops to be picked tea-leaves combing import between picking head in an orderly manner, can be convenient to follow-up proposing and adopt.
In order to realize the dark brownish green picking method of above-mentioned hoisting type, present invention also offers the dark brownish green picking head of a kind of hoisting type, as shown in Figure 1,2 and 3, this picking head is cylindrical or conical, and its front portion is introduction segment 1, and middle part is that the section of adopting 2 is put forward in clamping, rear portion is transmission segment 3, the cross section that the section of adopting 2 is put forward in described clamping is symmetrical multiple tooth form, and between cog teeth groove is straight trough or helicla flute, and the cross section of each tooth is rectangle or wedge shape.
In order to ensure that clamping can provide certain clamping dynamics after dark brownish green, prevent dark brownish green coming off, tooth in the section of adopting 2 is carried in described clamping to be had and is less than 3mm width seamed edge, and seamed edge relief angle α is less than 60 °.
In order to avoid lifting process damages dark brownish green blade-section, ensure into the quality and outward appearance of sampling tea, reduce the appearance of broken leaf, " close " conjunction minimum spacing with the adjacent picking head of group and be less than 1mm, " close " conjunction minimum spacing and can also select suitable spacing according to different local tea varieties, ensure best harvesting state.
In order to ensure dark brownish green clamping and realize importing smoothly, the quantity that tooth in the section of adopting 2 is carried in described clamping is 2 ~ 4.
For the ease of waiting to pick tea-leaves, blue or green smooth importing prevents dark brownish green blocking, and described introduction segment 1 is rectangle or taper.
In order to control cost and realize reverse function, described transmission segment can be gear.
