In the tea processing process, the picking mode of the tea is very important to the final quality of the tea. When high-grade tea leaves are picked, the picking mode of the tea leaves is required to be a handle picking method, and the handle picking method comprises the following steps: when the tea leaves are picked, after the forefinger and the thumb are clamped, the forefinger and the thumb are lifted upwards simultaneously, and the tea tips are forced to be separated from the tea tree bodies under the action of lifting force. The collection mode can ensure that the cells in the tea tip are completely separated from each other, so that the protection of 'membrane wall' is formed on the section, and the color change at the section is further prevented. Finally, the tea can be used for processing high-grade tea.

However, in order to meet the requirement of high-grade tea, most tea pluckers adopt a manual handle picking method for tea plucking, but the tea pluckers are prone to fatigue and pain of fingers due to large collecting amount, and the collecting efficiency is further reduced.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

Referring to fig. 1 to 3, the present invention provides a tea leaf picking device, which includes a housing 100, a clamping assembly 200 and a driving assembly 300 for collecting tea leaves.

Specifically, the bottom of the housing 100 defines a first opening 110, and one side of the housing 100 defines a second opening 120. The clamp assembly 200 includes a mounting block 210, a first resilient member 220, two links 230, two jaws 240, and a resilient distractor 250. The mounting block 210 is located within the interior cavity of the housing 100. The inside wall of the housing 100 is vertically provided with a downward sliding groove 130, and the mounting block 210 can slide up and down along the sliding groove 130, so as to guide the mounting block 210. One end of the first elastic member 220 is disposed on the top of the mounting block 210 and connected to the inner top surface of the housing 100, and the first elastic member 220 presses the mounting block 210 downward. The top portions of the two clamping jaws 240 are hinged to the bottom portion of the mounting block 210 by two connecting rods 230, respectively, and the bottom portions of the two clamping jaws 240 protrude from the first opening 110. A resilient distractor 250 is connected between the two jaws 240 to distract the two jaws 240. In particular embodiments, the elastic distractor 250 may preferably be a spring.

The driving assembly 300 is disposed on the housing 100 and connected to the clamping assembly 200, and can drive the whole clamping assembly 200 to ascend or descend relative to the housing 100, and the two clamping jaws 240 are gradually closed during the whole clamping assembly 200 ascends to the topmost part, and the two clamping jaws 240 are gradually separated during the whole clamping assembly 200 descends to the lowest end.

Under the normal state, the clamping assembly 200 is positioned below the shell 100 under the action of the first elastic member 220, at the moment, the tail ends of the two clamping jaws 240 are in a separated state under the action of the elastic spreader 250, a tea plucker can move the whole tea plucking device to a required place and enable a target tea tip to be plucked to be positioned between the two clamping jaws 240, then, the driving assembly 300 is started to drive the whole clamping assembly 200 to ascend, and the two clamping jaws 240 are gradually folded in a period of time before the ascending, so that the tea tip can be clamped; thereafter, the clamping assembly 200 continues to rise, and a lifting force can be applied to the tea point until the tea point breaks. After the clamping assembly 200 rises to the last upper end, the driving assembly 300 is loosened, the whole clamping assembly 200 is pushed to descend under the action of the restoring force of the first elastic piece 220, the clamping jaws 240 are gradually separated in the descending process of the clamping assembly 200, the collected tea tips can be discharged, and then, the second tea-picking operation can be carried out.

In this embodiment, the drive assembly 300 includes a guide plate 310, a handle 320, and a strut 330. There are two guide plates 310. The two guide plates 310 are transversely and oppositely arranged on two sides of the two clamping jaws 240 and are positioned close to the bottom of the mounting block 210, and the end part of each guide plate 310 is in sliding contact with the side wall of the clamping jaw 240 on the same side. The handle 320 is transversely disposed on the outer wall of the housing 100 where the second opening 120 is formed. The middle of the pressing rod 330 is hinged to the handle 320, one end of the pressing rod 330 is hinged to the bottom of the mounting block 210, and the other end of the pressing rod 330 extends out of the second opening 120.

In order to prevent the clamping jaws 240 from pinching the tea leaves, a soft pad 260 is provided on the opposite side of the ends of both clamping jaws 240. The soft pad 260 can protect the tea leaves to a certain extent.

When picking tea, the handle 320 and the pressure lever 330 are held by hand, the tail end of the pressure lever 330 is pressed downwards, the head end of the pressure lever 330 can lift the mounting block 210 to move upwards rapidly, the two clamping jaws 240 are gradually folded in the lifting process under the action of the two guide plates 310, the tea tip can be clamped, and then the two clamping jaws 240 continue to lift in a clasping state, so that the tea tip can be lifted until the tea tip is broken. After the mounting block 210 rises to the top end, the pressure lever 330 is loosened, the mounting block 210 moves downwards under the action of the first elastic piece 220, the two clamping jaws 240 are driven to move downwards, and the two clamping jaws 240 are gradually separated under the action of the elastic spreader 250, so that the tea leaf picking can be completed.

In this embodiment, in order to ensure that the pressing rod 330 can be smoothly reset, the driving assembly 300 further includes the second elastic member 340, and the second elastic member 340 is connected between the pressing rod 330 and the tail end of the handle 320. After the pressing rod 330 is released, the tail end of the pressing rod 330 is spread under the action of the second elastic member 340, so that the driving pressing rod 330 can be reset smoothly.

In a preferred embodiment, the guide plate 310 is provided with a roller 350 capable of rolling, and the guide plate 310 is in rolling connection with the side wall of the clamping jaw 240 through the roller 350. The friction force can be reduced.

The use mode of the tea leaf picking device is as follows:

when picking tea, the handle 320 and the pressure lever 330 are held by hands, a single target tea point is aligned between the two clamping jaws 240, then the tail end of the pressure lever 330 is pressed downwards, the two clamping jaws 240 are gradually closed, the tea point is clamped, and then the two clamping jaws 240 are lifted continuously in a clasping state to form a lifting force on the tea point until the tea point is broken. When the mounting block 210 is raised to the top, the pressing rod 330 is released, the two clamping jaws 240 are lowered and gradually separated, the collected tea tips can be discharged, and then, a second tea-collecting operation can be performed. By the picking mode, the tea leaves are picked by the lifting handle in the picking process, so that the color change of the section of the tea tip can be prevented, and the quality of the tea leaves is finally improved.
