Abstract

The utility model discloses a lifting type tea leaf picking head which comprises a picking head body. The whole picking head body is in a cylinder shape. One end of the picking head body for material removing is a flat-type clamping part, the other end of the picking head body is a cylindrical rolling part, the back end of the rolling part is fixedly connected with a rotating shaft, the tail end of the rotating shaft is provided with a gear, and a ridge with a back angle is arranged at the edge of the clamping part. The picking head is of an opposite-rotating type structure during rotating, the angle speed is the same, the rotating directions are opposite, accordingly, clamping and lifting of tea leaf stems are achieved, the picking mode is similar to picking by fingers of a human being, the problem that the sections of tea leaf become black quickly due to cutting of metal blades is avoided, the color and luster and quality of finished product tea cannot be affected, tea leaves and tea trees cannot be damaged, tattered leaves in the finished product tea can be avoided, the quality is further guaranteed, and meanwhile the effect that tea tree germination rate and yield are not affected is guaranteed.

Description

The dark brownish green picking head of a kind of hoisting type

Technical field

The utility model relates to the dark brownish green picking head of a kind of hoisting type, belongs to the design and manufacture technical field of agricultural machinery.

Background technology

At present, in order to guarantee dark brownish green quality, manual harvesting remains dark brownish green general picking method, generally completed by several workmans of picking tea-leaves, be divided into select, break-off type plucks and the step such as collection, pluck and can guarantee dark brownish green quality though manual, but there is the drawbacks such as picking efficiency is low, labour intensity is large, and because manual harvesting slowly can cause high-quality tea leaves aging, and can not pluck in time, affect the income of high-quality tea leaves, and then made dark brownish green harvesting become the procedure taking time and effort most in dark brownish green production process.

Another kind of picking method is that mechanical type is plucked, mechanical type is plucked and is completed by dark brownish green picking machine, dark brownish green picking machine is generally realized dark brownish green harvesting by the blade in petrol engine or electromotor band movement machine as cutting movement, though can significantly promote dark brownish green picking efficiency, but owing to cutting dark brownish green by sharp blade, make the rear dark brownish green rapid blackening of otch of cutting, have a strong impact on into the color and luster product phase of sampling tea; And sharp blade is in the time of high-speed motion, and part is dark brownish green not completely in normal cut state, can only cut to dark brownish green blade-section, make to save bit by bit in tealeaves a lot of broken leaves, subsequent handling need screen out these broken leaves, and dark brownish green raw material are wasted in a large number, and cost is very high; Meanwhile, dark brownish green picking machine also may damage tea tree, and causes the germination number step-down of tea tree, is unfavorable for long-term production in enormous quantities.

Utility model content

In order to solve the problems of the technologies described above, the utility model aim to provide a kind of simple in structure, do not destroy dark brownish green and tea tree, can guarantee the dark brownish green picking head of hoisting type of dark brownish green quality and color and luster.

The utility model is achieved by the following technical solution:

The dark brownish green picking head of a kind of hoisting type, comprise picking head body, described picking head body entire body is cylindrical, its one end is except expecting to be flat-shaped clamping part, the other end is cylindrical rolled portion, rolled portion rear end is connected with rotating shaft, and rotating shaft end is furnished with gear, and clamping part edge is also provided with the seamed edge with relief angle.

The relief angle α size of described seamed edge is 0 °～60 °.

The horizontal width of described seamed edge is 0.2～3mm.

Described rolled portion length is 1/4～1/3 of clamping part length.

Described clamping part front end is trapezoidal, taper or half-cone.

The beneficial effects of the utility model are:

Compared with prior art, the dark brownish green picking head of hoisting type that the utility model provides, the rotation of picking head adopts contrarotating structure, angular speed is identical, direction of rotation is contrary, thereby realize clamping and lifting to dark brownish green stem, bionical form, subhuman picking finger, can not cause the rapid blackening of dark brownish green section because of the cutting of metal blade, affect into the color and luster product phase of sampling tea, and also can not damage tealeaves and tea tree, prevent into the appearance of broken leaf in sampling tea, further guarantee quality, the germination rate that has simultaneously guaranteed tea tree, output is unaffected.

Embodiment

Below in conjunction with drawings and Examples, the technical solution of the utility model is described further, but described in desired protection domain is not limited to;

As shown in Figure 1, 2, the dark brownish green picking head of hoisting type that the utility model provides, comprises picking head body; Described picking head body entire body is cylindrical, and its one end is flat-shaped clamping part 1 except expecting, the other end is cylindrical rolled portion 2, and rolled portion 2 rear ends are connected with rotating shaft 3, and rotating shaft 3 ends are furnished with gear 4, and clamping part 1 edge is also provided with the seamed edge 5 with relief angle.

In order to guarantee clamping dynamics, the relief angle α size of described seamed edge 5 is 0 °～60 °.

In order to guarantee the intensity of described seamed edge 5, the horizontal width of seamed edge 5 is 0.2～3mm.

Described rolled portion 2 length are 1/4～1/3 of clamping part 1 length; It can prevent the too short rotation offset causing of rolled portion 2.

For the ease of dark brownish green importing and sub-sieve, described clamping part 1 front end is trapezoidal, taper or half-cone.

Embodiment 1: it is horizontally disposed to get eight picking head, and picking head parameters is respectively: the relief angle of seamed edge 5 is 5 °, and width is 0.2mm, and the length of rolled portion 2 is 1/4 of clamping part 1 length, and picking head front end is trapezoidal; In eight picking head, between adjacent two, realize synchronized reverse rotation by gear 4, in the time that the gap between clamping part 1 is maximum (clamping part 1 straight down), green grass or young crops to be picked tea-leaves is imported between picking head, along with the mutual reverse rotation of picking head, gap dwindles gradually, and seamed edge 5 is clamped dark brownish green stem and upwards lifted, the most dark brownish greenly break from dark brownish green stem, completed dark brownish green hoisting type and plucked.
