Description

Technical Field

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

[0002] Tea, as one of the world's three major beverages, owes its quality largely to the harvesting process. Currently, the production of high-end premium teas still heavily relies on purely hand-picking to ensure the integrity and standardization of the buds and leaves. However, this traditional method suffers from significant efficiency bottlenecks. Skilled tea pickers can only harvest a few kilograms of fresh leaves per day, resulting in extremely low yields of finished tea after processing.

[0003] With the migration of rural laborers to cities, the tea-picking workforce is aging and its numbers are declining sharply, leading to a prominent seasonal labor shortage and a continuous rise in labor costs. Furthermore, the efficiency of manual picking is constrained by weather, terrain, and the physical condition of the workers, resulting in poor stability and making it difficult to meet the market demands of large-scale, standardized production. This traditional model, reliant on intensive labor, has become a key bottleneck restricting the modernization and efficiency improvement of the tea industry. Therefore, exploring and applying mechanized and intelligent picking technologies has become an important direction that the industry urgently needs to overcome. Utility Model Content

Detailed Implementation

[0025] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0026] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Furthermore, the various embodiments of the invention, the features within those embodiments, and the features of the embodiments may be freely combined without obvious conflict or contradiction.

[0028] See Figures 1 to 7A tea picking and collecting device, comprising a collecting mechanism 1 and a collecting box 2. Specifically, the collection mechanism 1 includes a collection box 11, a cutting component 12, and a guiding component 13. The collection box 11 has a picking opening 111 and a collecting opening 112 at opposite ends along its length, which are connected to the collection box 11. A grid plate 115 is detachably connected inside the collection box 11. The grid plate 115 is set at an acute angle to the bottom plate of the collection box 11. In this embodiment, the cross-sectional area of ​​the picking opening 111 is larger than the cross-sectional area of ​​the collecting opening 112 to form a constricted opening. The grid plate 115 cooperates with the corresponding snap-fit ​​plate 114 inside the collection box 11 through its snap-fit ​​part. A detachable grid plate 115 is added inside the collection box 11. It is precisely snapped into the corresponding snap-fit ​​plate 114 inside the collection box 11 through the preset snap-fit ​​part to achieve a stable assembly. The grid plate 115 is inclined at a 45° acute angle inside the collection box 11. The snap-fit ​​plate 114 also relatively divides the interior of the collection box 11, forming a natural flow guiding and screening path. This design effectively prevents larger branches and leaves from entering the collection box 2 after shearing, avoiding pipe blockage or impurity contamination. When branches and leaves accumulate on the surface of the grid plate 115 due to long-term operation, they can be quickly disassembled by simply pulling them outwards, emptying and cleaning them, and then reassembled for reuse, making maintenance convenient and efficient. This structure not only ensures the purity of the tea leaves but also reduces the burden on subsequent sorting processes, improving the reliability and durability of the overall harvesting device.

[0029] Specifically, a guide component 13 is provided on the harvesting box 11. The guide component 13 is located at the end of the picking opening 111. The guide component 13 includes multiple guide brackets 131, rotating wheels 132, and a belt 133. The multiple guide brackets 131 are spaced apart at the end of the picking opening 111. A sharp part 134 is provided at the bottom of the guide bracket 131 away from the picking opening 111. The sharp part 134 protrudes outside the belt 133. Two rotating wheels 132 are movably connected to the guide bracket 131. The two rotating wheels 132 are connected by the belt 133. The sharp part 134 can be accurately inserted into the tea tree branches, enhancing the positioning stability of the picking opening 111 and preventing deviation. The spaced guide brackets 131 distribute the force and improve the structural durability. The rotating wheels 132 and the belt 133 cooperate to form a flexible conveying channel, providing more precise guidance for the tea stems and preparing for subsequent cutting, thereby improving harvesting efficiency and operation quality.

[0030] Specifically, a cutting assembly 12 is provided on the harvesting box 11. The cutting assembly 12 is movably connected to the harvesting opening 111 and is located above the guide assembly 13. The cutting assembly 12 includes a drive unit 121 and a movable cutter head unit 122. The drive unit 121 includes a motor 1211 and an eccentric coupling 1212. The motor 1211 is fixed on a connecting plate 116, which is fixedly connected to one side of the harvesting box 11. The output end of the motor 1211 is connected to one end of the eccentric coupling 1212 via a coupling. The other end of the eccentric coupling 1212 is connected to the movable cutter head unit 122 via a connecting rod 1213. The movable cutter head unit 122 is located above the guide assembly 13. The harvesting opening 111 faces away from the collection opening 112. The movable cutter head unit 122 is movably connected to the harvesting opening 111 and extends along the horizontal direction of the harvesting opening 111. After the motor 1211 is started, the output shaft of the motor 1211 is connected through one end of the eccentric coupling 1212. The other end of the eccentric coupling 1212 is connected to the shaft, which drives the movable cutter head unit 122 to reciprocate in the horizontal direction, so that the movable cutter head unit 122 can move closer to or further away from the fixed cutter head unit 123. This design converts the rotational power into linear reciprocating motion through the eccentric design of the eccentric coupling 1212. The structure is compact and the motion precision is controllable, ensuring that the cutting process is smooth and without jamming.

[0031] Specifically, the movable blade unit 122 includes a fixed base 1221, a slide rod 1222, and a slide rail 1223. The fixed base 1221 is fixed on the connecting plate 116. The motor 1211 is arranged opposite to the fixed base 1221. The slide rail 1223 is provided on the fixed base 1221. The end of the connecting rod 1213 away from the eccentric coupling 1212 is connected to one end of the slide rod 1222 via a coupling. The slide rod 1222 is slidably connected to the slide rail 1223. The slide rod 1222 is arranged horizontally along the harvesting opening 111. The harvesting box 11 has an opening 119 at the end away from the connecting plate 116. A support plate 120 is provided on the opening 119. A sliding groove is provided on the support plate 120. The end of the slide rod 1222 away from the coupling is slidably connected to the support plate 120. Multiple movable blades 12221 are arranged at intervals on the slide rod 1222. The slide rod 1222 is set horizontally and mounted on the connecting plate 116 via a fixed base 1221, ensuring overall rigidity. A groove is provided at the bottom of the slide rod 1222. The motor 1211 drives the eccentric coupling 1212, which in turn drives the slide rod 1222 to slide relative to the support plate 120 and the slide rail 1223. The eccentric rotational displacement of the eccentric coupling 1212 is converted into the linear sliding displacement of the slide rod 1222. The slide rail 1223 and the support plate 120 provide dual guidance to ensure motion accuracy. Movable cutting edges 12221 are evenly distributed around the slide rod 1222, forming a precise interlacing with the fixed cutting edges 1232 as the slide rod 1222 translates. The motor 1211 drives the eccentric coupling 1212 to transmit the slide rod 1222 to slide along the slide rail 1223, causing the movable cutting edges 12221 to approach the fixed cutting edges 1232 to complete the cutting. Upon pullback, the slide rod returns to its original position, achieving continuous and efficient cutting.

[0032] It should be noted that, in this embodiment, the eccentric coupling 1212 includes a connecting part 12121, a central shaft 12122, and an eccentric shaft 12123. The central shaft 12122 and the eccentric shaft 12123 are located at opposite ends of the connecting part 12121. The central shaft 12122 and the eccentric shaft 12123 are eccentrically arranged. By setting the length of the slide rail 1223 and the support plate 120 to be greater than the circumference of the rotation of the eccentric shaft 12123, the linear sliding displacement of the slide rod 1222 is ensured.

[0033] Specifically, the cutting assembly 12 also includes a fixed blade unit 123 mounted on a guide bracket 131. The fixed blade unit 123 includes a support column 1231 and a fixed blade 1232. The support column 1231 is fixed on the guide bracket 131, and the fixed blade 1232 is mounted on the support column 1231. The end of the slide rod 1222 away from the connecting shaft passes through multiple guide brackets 131. The fixed blade 1232 corresponds to the position of the movable blade 12221. Both the fixed blade 1232 and the movable blade 12221 are located between the two rotating wheels 132, and the blade of the fixed blade 1232 faces the blade of the movable blade 12221. Both the fixed blade 1232 and the movable blade 12221 are arc-shaped. During the cutting process, the two move towards each other and finally complete the cutting operation of the buds and leaves, realizing the effective separation of the buds and leaves from the tea stems. After the cutting is completed, the buds and leaves will fall into the semi-circular enclosed groove formed by the fixed blade 1232 and the movable blade 12221.

[0034] Specifically, a blower assembly 14 is provided on one side of the harvesting box 11. The air outlet of the blower assembly 14 faces the top of the cutting assembly 12. The blower assembly 14 includes a blower 141 and an air duct 142. The blower 141 is fixed to one side of the harvesting box 11. The air outlet of the blower 141 is connected to the air duct 142. The air duct 142 is provided with multiple branch pipes 143 at intervals along its length. The branch pipes 143 face the gap of the adjacent guide bracket 131 and are located at the top of the fixed blade 1232. The blower 141 accurately blows airflow to the top gap of the fixed blade 1232 through the multiple branch pipes 143, effectively blowing the buds and leaves into the harvesting box 11 to improve work efficiency.

[0035] Specifically, the harvesting box 11 is equipped with multiple lights 117 and batteries 118. The top of the harvesting box 11 has a grip 113, which includes a light switch 1131, a motor switch 1132, a blower switch 1133, and a negative pressure fan switch 1134. The batteries 118 are electrically connected to the light switch 1131, motor switch 1132, blower switch 1133, and negative pressure fan switch 1134, respectively. The batteries 118 serve as the core energy supply unit, ensuring continuous and stable operation of the equipment. The included lights 117 significantly expand its applicability, ensuring normal operation even in low-light conditions. The ergonomically designed grip 113 provides a comfortable grip experience for operators, and its integrated multi-functional independent control switches are rationally laid out, facilitating precise and efficient operation of various functions.

[0036] Specifically, the collection port 112 is connected to the collection box 2 via the connecting pipe 3. The top of the collection box 2 is equipped with a negative pressure fan 21, and the bottom of the collection box 2 is equipped with a hinged base plate. The side wall of the collection box 2 has a viewing window 22, and the collection box 2 is also equipped with a carrying strap 23. The adjustable carrying strap 23 makes it easy for operators to carry the box, significantly improving the convenience of operation. At the same time, a transparent viewing window 22 is provided to observe the loading status of the buds and leaves inside the collection box 2. During operation, the negative pressure fan 21 is turned on by the negative pressure fan switch 1134, creating a negative pressure inside the collection box 2. Combined with the blowing effect of the blower 141, the buds and leaves are brought into the collection box 2. When it is necessary to clean the buds and leaves, the material can be removed simply by opening the hinged base plate. The process is simple and efficient.

[0037] This invention guides tea leaves precisely into the picking opening 111 via a guide component 13. A cutting component 12 is movably connected above the guide component 13, flexibly cutting tea stems and reducing damage to buds and leaves. A blower component 14 delivers air to the top of the cutting component 12, promptly blowing the buds and leaves into the harvesting box 11. The collection opening 112 is connected to a collection box 2 with a negative pressure fan 21 via a connecting pipe 3. After picking, the buds and leaves are automatically drawn into the box by the airflow, eliminating the need for manual transfer. The top grip 113 facilitates hand operation, and the compact and flexible structure adapts to different tea-growing environments. This tea picking and collecting device integrates picking and collecting functions, is highly practical, improves overall picking efficiency, ensures the integrity of tea leaves, reduces labor intensity, and meets the needs of efficient harvesting.
