Description

Technical Field

[0001] This utility model relates to the field of agricultural harvesting tools, and in particular to a portable chrysanthemum quick-picking device. Background Technology

[0002] Chrysanthemums, especially those used for tea or medicine such as Gongju and Hangbaiju, are characterized by their concentrated flowering period and large harvest volume. Currently, small-scale chrysanthemum harvesting still relies heavily on manual labor, which is inefficient and labor-intensive. Some simple harvesting tools are available on the market, such as a comb-like harvesting shovel, which involves inserting the comb teeth into the flower cluster and using manual force to pull back and break the flower stems. However, this pulling-back harvesting method has the following obvious drawbacks: (1) The pulling force is difficult to control, which often damages the appearance of the flowers and may even uproot the entire plant. (2) The efficiency improvement is limited and the physical exertion on the operator is relatively large; in addition, the broken flowers are easy to fall, causing losses.

[0003] Therefore, developing a portable harvesting tool that is simple in structure, highly efficient in harvesting, and does not damage the flowers has significant practical value. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the issues of existing picking tools relying on pulling, easily damaging flowers, and being inefficient, and to provide a portable chrysanthemum quick-picking device.

[0005] To solve the above-mentioned technical problems, this portable chrysanthemum quick-picker includes a hollow shell, a stationary blade comb fixedly disposed at the lower part of the shell, and a moving blade comb horizontally reciprocating inside the shell. The stationary blade comb includes a stationary blade seat fixed at the lower edge of the front opening of the shell, and a plurality of stationary blade teeth spaced apart on the stationary blade seat and extending outward in a C- or J-shape, the inner edges of the stationary blade teeth forming stationary cutting edges. The moving blade comb includes a horizontally sliding moving blade seat, and moving blade teeth spaced apart on the moving blade seat, their shape matching the stationary blade teeth, the outer edges of the moving blade teeth forming moving cutting edges that cooperate with the stationary cutting edges. A collection cavity is formed inside the shell, a handle is provided at the top of the shell, and a drive mechanism for driving the moving blade comb to perform horizontal reciprocating motion is provided inside the shell.

[0006] Furthermore, the front end of the stationary blade tooth is integrally extended with a support rod, and multiple support rods together form a support platform. This support platform is used to temporarily support the cut flower and can guide the flower to the collection cavity when the shell is tilted.

[0007] Furthermore, the drive mechanism includes a trigger pivotally connected to the handle, a slide rail and an arm seat disposed within the housing, and a slotted slider and a crank arm connecting rod. The crank arm connecting rod includes an upper connecting rod and a lower crank arm. The lower part of the slotted slider is slidably mounted within the slide rail, and one side of the slotted slider is fixedly connected to the moving tool holder. The upper end of the connecting rod is hinged to the front end of the trigger, and the lower end of the connecting rod is hinged to one end of the crank arm. The other end of the crank arm passes through the arm seat, which serves as a fulcrum, and extends into the slot of the slotted slider.

[0008] Furthermore, the drive mechanism also includes a reset torsion spring, which is sleeved on the shaft of the trigger, with its two ends abutting against the inner side of the trigger and the inner wall of the handle, respectively, to apply a reset torque to the trigger to return it to its initial position.

[0009] This utility model discloses a portable chrysanthemum quick-picker, overcoming the shortcomings of existing picking tools that rely on pulling, easily damage flowers, and are inefficient. Through a combined internal and external shearing structure, it achieves non-destructive cutting of the flower stems, ensuring flower quality. Its C-shaped or J-shaped static comb automatically guides the flower stems to the optimal cutting point, while the front support platform effectively prevents flowers from falling and being lost. The entire machine adopts a purely manual mechanical structure, is durable, easy to operate, and significantly improves picking efficiency and quality. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0014] The present invention will be further described below with specific embodiments, but the scope of protection of the present invention is not limited to the following embodiments.

[0015] Implementation method 1: such as Figures 1 to 7As shown, this portable chrysanthemum quick-picker includes a hollow shell 1, a stationary blade comb 2 fixedly disposed at the lower part of the shell 1, and a moving blade comb 3 that reciprocates horizontally inside the shell 1. A collection cavity 11 is formed inside the shell 1, and a handle 12 is provided at the top. The stationary blade comb 2 includes a stationary blade seat 21 fixed at the lower edge of the front opening of the shell 1, and several stationary blade teeth 22 extending outward in a C-shape or J-shape spaced apart on the stationary blade seat 21. The inner edge of the stationary blade teeth 22 forms a sharp stationary cutting edge 23. This C-shaped or J-shaped structure is key to achieving automatic positioning of the flower stem; it can smoothly guide the flower stem to the optimal cutting area at the root using its geometry when the device is pushed forward. The moving blade comb 3 includes a horizontally sliding moving blade seat 31, and moving blade teeth 32 fixed thereon, whose shape matches the stationary blade teeth 22. The outer edge of the moving blade teeth 32 forms a moving cutting edge 33 that closely engages with the stationary cutting edge 23. The housing 1 also includes a drive mechanism 4, which drives the moving blade comb 3 to reciprocate horizontally relative to the stationary blade comb 2, thereby achieving a cutting action on the flower stem placed between them. This embodiment, through the cooperation of the stationary and moving blade combs, fundamentally solves the problem of traditional tools pulling and damaging flowers, achieving high-quality, damage-free harvesting.

[0016] Implementation method 2: such as Figures 4 to 7 As shown, the drive mechanism 4 of this portable chrysanthemum quick-picker is a manual four-bar linkage mechanism, which includes a trigger 41 pivotally connected to the handle 12, a slide rail 42 and an arm seat 43 disposed within the housing 1, as well as a slotted slider 44 and a curved arm linkage 45. The curved arm linkage 45 includes an upper link 451 and a lower curved arm 452; wherein, the lower part of the slotted slider 44 is slidably mounted in the slide rail 42, and one side of the slotted slider 44 is fixedly connected to the moving blade seat 31; the upper end of the link 451 is hinged to the front end of the trigger 41, and the lower end of the link 451 is hinged to one end of the curved arm 452, and the other end of the curved arm 452 passes through the arm seat 43, which serves as a fulcrum, and extends into the slot of the slotted slider 44. This structure can efficiently convert the circular motion of pressing the trigger 41 with a finger into the linear reciprocating motion of the moving blade comb 3. The remaining structures and components are as described in Embodiment 1 and will not be described again.

[0017] Implementation method 3: such as Figures 1 to 3 As shown, the front end of the stationary blade 22 of this portable chrysanthemum quick-picking device has an integrally extended support rod 24. Multiple support rods 24 together form a support platform, which is used to temporarily support the cut flowers. Simply tilt or stand the device upright to guide the flowers into the collection chamber 11. The collection chamber 11 narrows at the rear end and is equipped with a rear cover 111. Once a certain amount of flowers has been collected, the cover is opened at the rear end to empty the collection chamber 11. The remaining structures and components are as described in Embodiment 1 and will not be repeated.

[0018] In use: The operator holds handle 12, inserts the front end of the harvester into the chrysanthemum bushes, and pushes it forward. The C-shaped stationary blades 22 of the stationary comb 2 automatically guide the flower stems to the root cutting area. When several flower stems are felt to have entered, the operator pulls the trigger 41 with their thumb. The front end of trigger 41 rotates on the arm seat 43 via the lower end of the crank arm connecting rod 45. The front part of the lower end of the crank arm connecting rod 45 pushes against the groove wall of the slotted slider 44, causing it to move along the groove, which drives the moving comb 3 to complete a horizontal translation in an instant. The moving cutting edge 33 of the moving comb 3 interacts with the stationary cutting edge 23 of the stationary comb 2, cutting the flower stems at the junction of the flower and the stem. The operator releases their thumb, and the moving comb 3 returns to its original position under the action of the return torsion spring. The cut flowers fall directly onto the support platform below due to gravity. The operator can harvest flowers multiple times in a row. Once a certain number of flowers have accumulated on the support platform, the operator only needs to stand the device upright or tilt it backward. The flowers will then slide into the collection chamber 11 at the rear, completing an efficient collection.

[0019] This portable chrysanthemum harvester utilizes a combined internal and external shearing structure to cut flower stems without damage, ensuring flower quality. Its C-shaped or J-shaped static comb automatically guides the flower stem to the optimal cutting point, while the front support platform effectively prevents flowers from falling and being lost. The entire machine employs a purely manual mechanical structure, ensuring durability and ease of operation, significantly improving harvesting efficiency and quality. Specifically, (1) Harvesting without damage and high quality: The cutting action of the static comb and the dynamic comb is combined to cut the flower stems at the root, avoiding the pulling damage of traditional tools and ensuring the integrity and appearance of the flowers.

[0020] (2) Precise positioning and high efficiency: The C-shaped or J-shaped structure of the static comb can automatically guide the flower stem to the best cutting position during the forward push. The operator only needs to press the trigger to complete the picking. The action is smooth and the efficiency is significantly improved.

[0021] (3) Clever structure to prevent falling: The support rod extending from the front end of the stationary blade forms a support platform, which can temporarily support the cut flowers and effectively prevent them from falling and being lost. The design is humane.

[0022] (4) Simple structure, reliable and durable: It adopts a pure manual mechanical transmission structure, which does not require power supply. The structure is simple and reliable, easy to maintain, and suitable for use in complex field environments.
