Description

Technical Field

[0001] The invention relates to the technical field of tea plucking equipment, in particular to a self-adaptive profiling tea plucking machine for high-quality and famous teas. Background Art

[0002] Existing mechanized tea picking technologies fall into two main categories: bulk tea picking machines, which utilize a reciprocating cutter as their primary component and employ a pruning-style plucking principle. While relatively mature, these machines can only handle bulk tea leaves of low-quality appearance. Humanoid robotic picking technology, specifically for premium teas, comprises key components such as a vision system, a robotic arm, and an end-point actuator. Currently in the exploratory research phase, mature, practical technologies are not yet available. The tea industry has long awaited the development of premium tea mechanization, but this challenge remains unresolved. Among existing premium tea picking technologies, computer vision recognition is commonly used for visual identification of tea leaves, employing traditional digital image processing and deep learning models and algorithms. Common end-point actuators include shearing, pinching, and squeezing mechanisms, all of which achieve the desired effect by simulating the plucking process of human fingers. Premium teas place stringent demands on appearance, demanding not only a complete and beautiful appearance, but also a beautiful aesthetic. All of the above picking methods require a visual system to accurately locate the tea buds and pick them individually, which theoretically results in higher picking quality. However, precise positioning is generally difficult to achieve, so the production efficiency and quality are far lower than manual labor.

[0003] In summary, the existing technology for picking high-quality tea has problems such as low positioning accuracy of the visual system, slow speed and low efficiency of the picking mechanism and control system. The picking quality and production efficiency are difficult to meet actual requirements. Therefore, the problem of picking high-quality tea has been difficult to solve, which has seriously hindered the development of the industry. Summary of the Invention

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] The purpose of the invention is to provide a self-adaptive tea-picking machine for picking high-quality tea, so as to solve the problems existing in the prior art.

[0047] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] Example 1:

[0049] The self-adaptive profiling tea picking machine for high-quality tea in this embodiment is as follows: Figures 1-11 As shown, it includes a walking chassis 1, a frame 2, a collection fan system 3, an air supply duct system 4, a picker floating link 5 and a picker system 6;

[0050] The frame 2 is arranged on the top of the walking chassis 1, and the walking of the frame 2 is achieved by pulling the walking chassis 1;

[0051] The collecting fan system 3 is arranged on the frame 2 and connected to the air supply duct system 4, and supplies air to the picking device system 6 through the air supply duct system 4;

[0052] The picker system 6 is arranged at the bottom of the air supply duct system 4 and is connected to the frame 2 through the picker floating connecting rod 5. The two ends of the picker floating connecting rod 5 are hinged to the frame 2 and the picker system 6 respectively;

[0053] The picking device system 6 includes a profiling plate 6-1, a cutting groove 6-2 and a tea delivery transition frame 6-3 arranged in sequence from front to back; the profiling plate 6-1 is used to profile the surface of the tea shed, and the cutting groove 6-2 is a strip groove distributed longitudinally and has a plurality of grooves distributed transversely. Each groove body includes two groove walls 6-2-2, and the two groove walls 6-2-2 of each groove body are oppositely provided with guide belts 6-2-3. The end section of the guide belt 6-2-3 can be set as a cutting edge 6-2-4 for cutting tea buds.

[0054] The tea conveying transition frame 6 - 3 is used to hang the tea leaf collecting net bag to collect the tea leaves picked by the picking system 6 .

[0055] In this specific embodiment, the collection fan system 3 includes a fan and a drive motor arranged on the middle crossbeam at the top of the frame 2, and the fan is driven by the drive motor.

[0056] In this specific embodiment, the air supply duct system 4 is fixed on the frame 2 and is located directly below the collection fan system 3. The air supply duct system 4 is connected to the air outlet of the fan through a pipe.

[0057] In this specific embodiment, two picker floating links 5 are provided and symmetrically arranged on both sides of the profiling plate 6-1. One end of the picker floating link 5 is hinged to the frame 2 through a pin shaft, and the other end is hinged to the hinge ears 6-1-1 arranged on both sides of the profiling plate 6-1 through a pin shaft.

[0058] In this specific embodiment, the front end of the profiling plate 6-1 is an upward curved arc plate structure, and the rear end is a flat plate structure, and the two are smoothly transitioned. The hinge ears 6-1-1 are set on both sides of the flat plate structure.

[0059] In this embodiment, the cutting groove 6-2 is provided at the rear end of the profiling plate 6-1. The top plate of the cutting groove 6-2 and the flat plate structure of the profiling plate 6-1 are an integrally formed structure, that is, it is an extension of the flat plate structure.

[0060] In this specific embodiment, the cutting groove 6-2 is a rectangular groove, and three layers of guide belts 6-2-3 are arranged in parallel on the two groove walls 6-2-2 of each cutting groove 6-2. The guide belts 6-2-3 on the same layer of the two groove walls 6-2-2 constitute a pair of guide belts 6-2-3. The tail end of at least one pair of the three pairs of guide belts 6-2-3 is a cutting edge 6-2-4. Each guide belt 6-2-3 is distributed along the inner wall of the groove from top to bottom and from front to back, gradually bending downward and gradually becoming horizontal backward. The vertical spacing between the guide belts 6-2-3 of each layer is equal, and the width of each guide belt 6-2-3 increases from front to back, so that the gap between the two guide belts 6-2-3 of each layer gradually decreases, and the lateral gap between the two guide belts of each layer decreases from top to bottom. According to different standards for picking tea tips, the cutting edge 6-2-4 is set at the tail end of the two guide belts 6-2-3 of one layer. The multi-layer guide belts achieve the effect of layered guidance, guiding the tea bud tips along the cutting groove to the middle (the symmetry plane), and separating the leaves from the bud tips. The leaves are perpendicular to the stems of the tea buds, so that when the blade is cut later, only the stems are cut without losing the leaves. The multi-layer guide belts can also be set according to the needs of picking, so different lengths can be picked, and picking can be done in layers.

[0061] In this specific embodiment, the two sides of the rear end of the cutting groove 6-2 are connected to the tea conveying transition frame 6-3 through S-shaped pins, and shaft sleeves 6-2-1 are set on both sides of the rear end of the cutting groove 6-2, and shaft sleeves 2 6-3-4 are set on both sides of the front end of the tea conveying transition frame 6-3. The front section of the S-shaped pin is hinged to the shaft sleeve 1 6-2-1, and the rear section of the S-shaped pin is hinged to the shaft sleeve 2 6-3-4.

[0062] In this specific embodiment, the tea conveying transition frame 6-3 includes a transition frame 6-3-1, a leaf collecting mesh belt hanging interface 6-3-2 and a leaf collecting mesh belt fixing ear 6-3-3. The leaf collecting mesh belt hanging interface 6-3-2 is in the shape of a rectangular frame and is fixed to the tail of the transition frame 6-3-1. There are 4 leaf collecting mesh belt fixing ears, which are respectively welded to the four corners of the leaf collecting mesh bag hanging interface. The leaf collecting mesh belt hanging interface 6-3-2 is used to support the bag opening of the leaf collecting mesh belt and strengthen the tea conveying transition frame 6-3. The leaf collecting mesh belt fixing ear 6-3-3 is used to connect the bag opening of the leaf collecting mesh belt.

[0063] In this embodiment, the main function of the slitting groove 6-2 is to cut the tea shed surface longitudinally into long strips, ensuring that the cross-section of the strip contains a small number of tea buds (typically 0-3). The guide belt 6-2-3 primarily separates the buds and leaves of the tea leaves. As the plucking device slides along the tea shed surface, the tea leaves move backward relative to the plucking device, sequentially entering the slitting groove 6-2 and moving backward along the guide belt 6-2-3. The guide belt 6-2-3 guides the tea leaves in two ways: first, it gathers the tea leaves toward the center of the slitting groove 6-2; second, it presses the larger leaves of the tea leaves downward, keeping them as perpendicular to the stems as possible, so that the rear section of the guide belt 6-2-3 does not cut the leaves when cutting the stems. Thanks to the dual action of the groove wall and the guide belt, the tea leaves moving within the slitting groove 6-2 are always in a vertical position. After exiting the slitting groove, the tea buds directly enter the tea conveyor transition frame 6-3. The rear end of the tea conveyor transition frame 6-3 is equipped with an interface for attaching a tea net bag to collect the picked tea leaves. A traction and attachment mechanism is located at the front of the tea plucking device, allowing for manual traction or attachment to a powered platform for tea bud harvesting. This device offers advantages such as a simple structure, no need for cutting and profiling power, and consistent picking quality.

[0064] The operation process is as follows: The picking device system 6, under the guidance of a mobile tea picking platform or manual traction, slides along the surface of the tea canopy, where neatly trimmed tea leaves are located. The profiling plate 6-1 profiles the tea canopy surface, ensuring that the cutting groove 6-2 is always positioned at a fixed depth below the canopy top surface. The young tea leaves move backward relative to the picking device and sequentially enter the cutting groove 6-2. Guided, gathered, and pressed by the guide belts 6-2-3 on each layer, they are kept upright and their stems nearly vertical. When they reach the latter half of the cutting groove 6-2, they are cut by the cutting edges 6-2-4 of a pair of guide belts 6-2-3. Pushed by the remaining tea leaves (the cutting wall principle), they are pushed out of the cutting groove 6-2 and into the tea conveyor transition frame 6-3. Under relative motion or the force of the fan, they enter the tea collection network. The tea picking process is thus completed. The profiling function is primarily performed by the flat plate at the front of the picking device. The front end of this plate is curved upward to prevent it from being blocked by the tea leaves, allowing it to glide smoothly along the tea canopy surface. The profiling plate 6-1 ensures uniform size of the picked tea tips (a fixed distance downward from the canopy top). The central portion of the picker is its core. This picker system 6 can be powered by mechanical traction or manually hauled. It offers advantages such as a simple structure, no need for cutting and profiling power, and consistent picking quality. This technology provides equipment and technical support for solving the challenges of machine-harvesting high-quality teas.

[0065] Example 2:

[0066] The difference between this embodiment and the first embodiment is that:

[0067] like Figure 12As shown, the rear section of the cutting groove 6-2 is rectangular and the front section is conical, which plays a role in peeling off the leaves below the buds of the tea shoots; a guide belt 6-2-3 is respectively arranged on the two groove walls 6-2-2 of the cutting groove 6-2, and the tail ends of the two guide belts 6-2-3 are cutting edges. Each guide belt 6-2-3 is distributed along the inner wall of the groove from top to bottom and from front to back, gradually bending downward and gradually horizontalizing backward. The height of the two guide belts 6-2-3 is set according to different picking standards.

[0068] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
