Description

Technical Field

[0001] This utility model relates to the field of tea picking technology, and in particular to a tea picking mechanism and picking equipment. Background Technology

[0002] Manual tea picking has a long history and offers irreplaceable advantages for certain tea varieties with high quality requirements. However, for teas of average quality or those harvested outside their optimal picking time, manual picking is inefficient, time-consuming, labor-intensive, and costly. In contrast, tea-picking machines can be used to harvest these types of tea.

[0003] Some tea-picking machines are not portable and require manual pushing or self-movement in the tea garden. These machines are generally large and use sharp blades to cut the tea leaves, collecting them through negative pressure adsorption. Some machines use manual blades for cutting, which undoubtedly requires repeated operation and cuts a small number of leaves at a time, significantly increasing the manual burden during long harvesting periods.

[0004] For example, patent publication number CN221228274U discloses an integrated device for tea picking and storage, in which shearing blades are symmetrically slidably connected inside the picking cover. The shearing blades are manually pressed to cut the tea leaves. The number of leaves that can be cut at one time is small, and the shearing blades need to be mechanically pressed repeatedly. Summary of the Invention

[0005] To address the problem that some tea-picking machines still require frequent manual cutting operations, this utility model provides a tea-picking mechanism and equipment. The electric-driven shearing blades continuously rotate to cut tea leaves in batches, greatly reducing the amount of manual operation. At the same time, the picking equipment facilitates the centralized collection of the cut tea leaves.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A tea picking mechanism includes a picking seat and a shearing unit for picking tea leaves. The picking seat is a channel structure with an open front and back, which facilitates the flow of tea leaves from front to back within the picking seat. The picking seat is wider at the front and narrower at the back, which facilitates the concentration and gathering of tea leaves. The upper front of the picking seat is open, which facilitates the observation of the tea leaf cutting process. A collection port for concentrating tea leaves is provided at the front of the picking seat to facilitate the guidance and gathering of tea leaves. The shearing unit is also provided at the front of the picking seat. The shearing unit includes a drive motor and a shearing blade controlled by the drive motor. The rotation range of the shearing blade covers the collection port, which facilitates the cutting of tea leaves within the collection port.

[0008] Furthermore, the picking stand includes a collection section and a channel section integrally formed at the front and back. The width of the collection section is greater than the width of the channel section. The collection section and the channel section have a smooth arc transition. The top of the collection section is open. The collection port and the shearing unit are both arranged on the collection section.

[0009] Furthermore, a hand-held handle is provided above the picking seat to facilitate manual handling of the picking seat. The hand-held handle extends from the front end to the rear end of the picking seat, and the cross-section of the hand-held handle is in the shape of "[".

[0010] Furthermore, the collection port is a long, thin strip structure, with one end of the collection port penetrating through the picking seat, and there are two collection ports arranged side by side.

[0011] Furthermore, the drive motor is located below the picking seat, and the output axis of the drive motor extends upward into the picking seat and is connected to the shearing blade, the shearing blade having an "X" shaped cross section.

[0012] Furthermore, a limiting ring is provided inside the picking seat, and the limiting ring has a notch. The position of the notch corresponds to the position of the collecting port, and the shearing blade is arranged inside the limiting ring.

[0013] A limiting cover is also provided above the limiting ring. The limiting cover has a notch, the position of which corresponds to the position of the collection port. The limiting cover covers the shearing blade, improving the safety of using the shearing blade.

[0014] A tea picking device includes the picking mechanism described above, and also includes a collection frame and a blower mechanism. The collection frame is located at the rear end of the picking seat and is connected to the picking seat. The blower mechanism is located at the front end of the picking seat. The blower mechanism, the picking seat and the collection frame are arranged in sequence. The blower mechanism generates airflow to blow the tea leaves cut by the shearing unit through the picking seat into the collection frame.

[0015] Furthermore, the collection frame includes a housing and a cover attached to the top of the housing. The housing is a rectangular groove structure made of transparent plastic with an open top, and the cover is a perforated mesh structure.

[0016] Furthermore, the blower mechanism includes a mounting frame and a duct fan mounted on the mounting frame. The mounting frame has a U-shaped cross-section, and the duct fan is located in the middle of the mounting frame. The air outlet of the duct fan faces the picking seat, and both ends of the mounting frame are bolted to the picking seat.

[0017] The beneficial effects of this utility model through the above technical solution are:

[0018] The picking stand of this invention has a channel structure, which facilitates the flow of tea leaves from the front end to the rear end of the picking stand. The front end of the picking stand has a collection port, which helps to guide and gather the tea leaves, causing them to concentrate in the collection port. The front end of the picking stand also has a shearing blade controlled by a drive motor. The rotating shearing blade quickly cuts the tea leaves in the collection port, thereby realizing automated picking operations.

[0019] The picking equipment of this utility model consists of a blower mechanism, a picking seat, and a collection frame arranged in sequence. Based on the picking seat being able to cut the tea leaves, the blower mechanism blows air into the picking seat through a pipe fan, thereby blowing the cut tea leaves through the picking seat into the collection frame for temporary storage of the tea leaves. This reduces the need for a large amount of manpower in the entire picking process and improves picking efficiency. Attached Figure Description

Detailed Implementation

[0025] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0026] like Figures 1-3 As shown, a tea picking mechanism includes a picking seat 1 and a shearing unit 2 for picking tea leaves. The picking seat 1 is a handheld component that needs to be used by hand. The picking seat 1 has a channel structure with open front and back, and the interior of the picking seat 1 is a channel cavity of a certain length. This channel is the channel for collecting and flowing tea leaves, and the tea leaves will flow inside the picking seat 1.

[0027] The picking seat 1 includes a collecting section 101 and a channel section 102 which are integrally formed front and back. There is a smooth arc transition between the collecting section 101 and the channel section 102. The cross-section of the collecting section 101 is in a "凵" shape, and the cross-section of the channel section 102 is in a "口" shape. The picking seat 1 is wider at the front and narrower at the back, that is, the width of the collecting section 101 is greater than the width of the channel section 102; the front end of the picking seat 1 is open above, that is, the collecting section 101 is open above.

[0028] A collecting port 3 for concentrating tea leaves is provided at the front end of the picking seat 1. After the tea leaves are placed in the collecting port 3, it is convenient for the shearing unit 2 to cut them off. The number of collecting ports 3 is two arranged in parallel. The collecting port 3 is a slender strip structure. Here, the collecting port 3 is a U-shaped port. One end of the collecting port 3 penetrates through the picking seat 1, facilitating the tea leaves to be placed into the picking seat 1 through the collecting port 3.

[0029] A shearing unit 2 is also provided at the front end of the picking seat 1. Specifically, both the collecting port 3 and the shearing unit 2 are arranged on the collecting section 101. The shearing unit 2 includes a driving motor 21 and a shearing blade 22 controlled by the driving motor 21. The operation of the driving motor 21 can drive the shearing blade 22 to rotate circumferentially. The driving motor 21 uses a micro DC motor.

[0030] When the shearing unit 2 is installed, the driving motor 21 is arranged below the picking seat 1. The output shaft of the driving motor 21 extends vertically upward into the picking seat 1 and is connected to the shearing blade 22. The cross-section of the shearing blade 22 is in a "×" shape, and the rotation range of the shearing blade 22 covers the two collecting ports 3. It is convenient to simultaneously shear the tea leaves in the two collecting ports 3 through the high-speed rotating shearing blade 22.

[0031] In order to improve the safety of the rotation of the shearing blade 22, a limiting ring 4 is provided in the picking seat 1. The limiting ring 4 has a notch, and the position of the notch corresponds to the position of the collecting port 3. Thus, the limiting ring 4 is divided into two segments, a major arc segment and a minor arc segment. The shearing blade 22 is arranged inside the limiting ring 4.

[0032] At the same time, a limiting cover 5 is connected above the limiting ring 4 through a set screw. The limiting cover 5 has a notch, and the position of the notch corresponds to the position of the collecting port 3. The limiting cover 5 covers above the shearing blade 22. Through the cooperation of the limiting ring 4 and the limiting cover 5, the shearing blade 22 can be restricted within a certain space to prevent the blade from hurting people. However, it should also be noted not to place the hand inside the collecting port 3 during use.

[0033] In order to improve the convenience of using the picking seat 1, a hand-held rod 6 is also provided above the picking seat 1. The hand-held rod 6 extends from the front end to the back end of the picking seat 1. The cross-section of the hand-held rod 6 is in a "[" shape, and the lengths of both ends of the hand-held rod 6 are different. By holding the hand-held rod 6, it is convenient to pick up the picking seat 1.

[0034] When in use, the picking stand 1 is worn by workers in a waist pack containing a DC lithium battery pack. The DC lithium battery pack is connected to the drive motor 21 via wires to power the drive motor 21. After the drive motor 21 drives the shearing blade 22 to rotate at high speed, the worker moves the picking stand 1 by hand. The entire picking stand 1 is similar to a shovel. During the movement, the tea leaves are automatically gathered by the collection port 3 and guided to the position of the shearing blade 22, thereby realizing the cutting and picking of the tea leaves.

[0035] like Figure 4 As shown, a tea-picking device includes a picking mechanism, a collection frame 7, and a blower mechanism 8. The collection frame 7 is located at the rear end of the picking seat 1 and is connected to the picking seat 1. The picked tea leaves enter the collection frame 7. The collection frame 7 includes a housing 71 and a cover 72 that is connected to the top of the housing 71. The housing 71 is a rectangular groove structure made of transparent plastic with an open top. The cover 72 is a perforated mesh structure and is used to open and close the collection frame 7.

[0036] The blower mechanism 8 is located at the front end of the picking seat 1. The blower mechanism 8, the picking seat 1, and the collection frame 7 are arranged in a front-to-back sequence. In this way, the blower mechanism 8 generates airflow to blow the tea leaves cut by the shearing unit 2 through the picking seat 1 into the collection frame 7. After a certain amount of tea leaves are stored in the collection frame 7, they are then taken out and placed into a larger container such as a basket.

[0037] The blower mechanism 8 includes a mounting frame 81 and a duct fan 82 mounted on the mounting frame 81. The mounting frame 81 has a U-shaped cross-section, and the duct fan 82 is located in the middle of the mounting frame 81. There is at least one duct fan 82. The duct fan 82 passes through the mounting frame 81. The duct fan 82 can be a 2-inch / 50mm diameter DC duct fan. The duct fan 82 is connected to a DC lithium battery pack in the waist pack via wires to power the duct fan 82.

[0038] The outlet of the duct fan 82 faces the picking seat 1, thus blowing the cut tea leaves backward and into the collection frame 7. The mounting bracket 81 is connected to the picking seat 1 at both ends by mounting bolts 9, which include bolts and nuts, and the nuts can be hand-tightened. This allows the outlet angle of the duct fan 82 to be adjusted by loosening the mounting bolts 9.

[0039] Meanwhile, elongated adjustment holes 10 are made on both sides of the mounting bracket 81. The mounting bolts 9 pass through the adjustment holes 10 and connect to the picking seat 1, so that the distance between the outlet of the duct fan 82 and the shearing unit 2 can be adjusted. By adjusting the distance and angle, the tea leaves can be blown more effectively. After tightening the mounting bolts 9, the duct fan 82 can maintain a fixed position and angle.

[0040] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
