Description

Technical Field

[0001] This utility model relates to the field of biological culture tools, and more specifically, to a ginseng adventitious root cutting knife. Background Technology

[0002] As a precious medicinal plant, the root system structure of ginseng has a significant impact on its quality and yield. During the cultivation of ginseng, the growth of adventitious roots consumes excessive nutrients and affects the development of the taproot. Therefore, it is necessary to prune the adventitious roots in a timely manner.

[0003] Currently, the angle adjustment aspect is particularly prominent in the cutting of ginseng adventitious roots cultivated in culture containers. The limited space within the culture container and the complex growth morphology of adventitious roots—including those growing obliquely, laterally, and almost vertically—often intertwine with other root systems. Furthermore, some adventitious roots grow at the edges or corners of the container, all of which place extremely high demands on the angle adjustment capability of the cutting tools. However, existing ordinary cutting tools have significant shortcomings in angle adjustment. Most ordinary cutting tools lack angle adjustment functionality altogether; the blade and handle are at a fixed angle, unable to be flexibly adjusted according to the growth angle and position of the adventitious roots. This makes it difficult to align the blade at the optimal cutting point, resulting in low cutting precision and the risk of damaging surrounding healthy roots. The few ordinary cutting tools that do have angle adjustment functions have poorly designed adjustment structures, resulting in poor stability after adjustment. They are prone to angle deviation during cutting, affecting operational safety, and the adjustment process is cumbersome, requiring additional tools for tightening and fixing. In addition, the handle length of ordinary knives is fixed and cannot be adjusted according to the depth of the culture container and the operating space. The blades are mostly non-removable and need to be replaced as a whole after wear, which also exacerbates the inconvenience of operation. Utility Model Content

[0004] The present invention aims to solve the problems of insufficient angle adjustment capability, low cutting accuracy, poor operational flexibility, and non-removable blade when ordinary knives are used to cut ginseng adventitious roots in culture containers.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a ginseng adventitious root shearing knife, comprising a handle, a connecting plate, and a blade body, wherein the handle, the connecting plate, and the blade body are arranged sequentially from top to bottom; one end of the blade body is a cutting edge, and the other end of the blade body is threadedly connected to the connecting plate; the connecting plate is hinged to the connecting part of the handle; the connecting plate has several limiting holes evenly distributed along its circumference; the connecting part is provided with a movable limiting member, which can extend into the limiting holes and restrict the rotation of the connecting plate; a miniature LED light is provided on the handle near the blade body; the handle includes a hand grip, which is a multi-stage telescopic sleeve structure.

[0006] Furthermore, the connecting part has a threaded hole, the limiting member is a hexagonal bolt, the hexagonal bolt is disposed in the threaded hole, the connecting disc is a fan-shaped toothed disc, the limiting opening is a toothed groove, and the hexagonal bolt can pass through the threaded hole, extend into the toothed groove, and abut against the tooth.

[0007] Furthermore, the handheld part includes an inner tube and an outer tube, the inner tube is inserted into the outer tube, the outer side wall of the inner tube is provided with an elastic limiting bead, and the side wall of the outer tube is provided with a plurality of limiting holes, the inner tube and the outer tube are engaged through the elastic limiting bead and the limiting holes.

[0008] Furthermore, the blade body is made of food-grade stainless steel, and the blade surface is coated with a ceramic anti-stick coating.

[0009] Furthermore, an elastic element is attached to the gear teeth. Furthermore, an adjustable bracket is provided on the tool holder, and the LED light is mounted on the adjustable bracket.

[0010] Furthermore, the outer surface of the handheld part is provided with anti-slip texture, and the end of the handheld part is provided with a hanging hole.

[0011] Furthermore, the blade surface is provided with a mesh-like pattern.

[0012] Furthermore, the connecting disc is connected to the tool holder by rivets.

[0013] Furthermore, the tip of the blade is rounded.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: The overall structural design of the shearing blade is adapted to the narrow space of the culture container, allowing for easier insertion into the container for shearing operations. It adapts to the complex spatial environment within the culture container, offering high operational flexibility. The surface of the blade features a mesh pattern to prevent slippage of adventitious roots, facilitating precise control of the shearing position by the operator. The rounded tip of the blade prevents accidental punctures during insertion into the culture container, enabling rapid shearing, reducing operation time, and improving shearing efficiency. The inclusion of a miniature LED light illuminates the shearing area in low light conditions, allowing the operator to clearly see the details of the adventitious roots, further ensuring shearing accuracy and preventing damage to surrounding roots. The blade body is detachably mounted on the connecting plate via threaded holes and screws, enabling a detachable connection. When the blade wears down, only the blade needs to be replaced, eliminating the need to replace the entire tool. Reduced operating costs: The handle is hinged to the connecting plate, which is fixed by a limiting port and limiting components to prevent the blade on the connecting plate from shifting angle when cutting adventitious roots. In addition, the blade angle can be adjusted by rotating the connecting plate, allowing the blade to be aligned with the cutting point in the optimal position. For adventitious roots growing on the edge or corner of the culture container, the angle can be adjusted to allow the cutting blade to penetrate smoothly, avoiding tool jamming or root damage caused by forced operation due to an unsuitable angle. The handle has a multi-stage telescopic sleeve structure to meet the needs of culture containers of different depths and different operating spaces. When operating in shallow culture containers or confined spaces, retracting the handle can improve flexibility. When operating in deeper culture containers, extending the handle can prevent the hand from contacting the adventitious roots, keeping the operation clean and convenient. The anti-slip texture of the handle can increase the friction between the hand and the handle to prevent slippage during operation. Attached Figure Description

[0020] Example like Figures 1-4 As shown, this utility model discloses a ginseng adventitious root cutting knife. The cutting knife includes a handle 100, a connecting plate 200, and a blade 300, which are arranged sequentially from top to bottom. One end of the blade 300 is a cutting edge 301, and the other end of the blade 300 is threadedly connected to the connecting plate 200. The connecting plate 200 is hinged to the connecting part 110 of the handle 100. The connecting plate 200 has several limiting holes 210 evenly distributed along the circumference of the connecting plate 200. The connecting part 110 is provided with a movable limiting member 111, which can extend into the limiting hole 210 and restrict the rotation of the connecting plate 200. A miniature LED light 130 is provided on the handle 100 near the blade 300. The handle 100 includes a handhold part 120, which is a multi-stage telescopic sleeve structure. In use, the operator first adjusts the length of the handle 120 according to the depth of the culture container and the operating space; then, the shearing blade is inserted into the culture container to observe the root distribution inside the culture container. If the light is insufficient, the LED light 130 is turned on; when adjusting the angle of the blade body 300, the position of the limiting member 111 is first adjusted to move it away from the limiting port 210. Then, the blade body 300 is rotated around the hinge point to the target angle. Finally, the position of the limiting member 111 is adjusted so that it extends into the limiting port 210 to fix the angle; the operator holds the handle 100 and aligns the blade 301 with the adventitious root to be cut before cutting; when the blade 301 is worn, the screw is loosened and the blade 301 is replaced.

[0021] The connecting part 110 is provided with a threaded hole, and the limiting member 111 is a hexagonal bolt 112. The hexagonal bolt 112 is set in the threaded hole, the connecting plate 200 is a sector-shaped gear plate 220, and the limiting port 210 is a tooth groove 221. The hexagonal bolt 112 can pass through the threaded hole and extend into the tooth groove 221 to abut against the gear teeth 222. When adjusting the angle of the cutter body 300, first rotate the hexagonal bolt 112 to move it away from the sector-shaped gear plate 220, then rotate the sector-shaped gear plate 220 to adjust it to the preset position, and finally tighten the hexagonal bolt 112 so that the hexagonal bolt 112 is close to the sector-shaped gear plate 220 and extends into the tooth groove 221 to abut against the gear teeth 222, thus fixing the sector-shaped gear plate 220.

[0022] The aforementioned handheld part 120 includes an inner tube 122 and an outer tube 123. The inner tube 122 passes through the outer tube 123. An elastic limiting bead 124 is provided on the outer side wall of the inner tube 122, and multiple limiting holes 125 are provided on the side wall of the outer tube 123. The inner tube 122 and the outer tube 123 are engaged by the elastic limiting bead 124 and the limiting holes 125. When the length of the handheld part 120 needs to be adjusted, the elastic limiting bead 124 is pressed first, and then the position between the inner tube 122 and the outer tube 123 is adjusted. When the sleeve extends or retracts to the target length, the elastic limiting bead is engaged in the limiting hole 125 to fix the length.

[0023] The blade body 300 is made of food-grade stainless steel, and the blade 301 is coated with a ceramic anti-stick coating. The ceramic anti-stick coating not only has excellent anti-stick properties, but also improves the wear resistance and corrosion resistance of the blade 301, extending the service life of the tool.

[0024] An elastic element is attached to the aforementioned gear tooth 222. The elastic element is made of rubber. This elastic element can prevent the hexagonal bolt 112 and the gear tooth 222 from directly contacting each other, reducing mutual friction. At the same time, the elastic element has elastic properties that can eliminate the gap between the hexagonal bolt 112 and the gear tooth 222, thus better fixing the sector gear disk 220.

[0025] The aforementioned tool holder 100 is equipped with an adjustable bracket, and the LED light 130 is mounted on the adjustable bracket, so that the position of the LED light 130 can be flexibly adjusted.

[0026] The outer surface of the aforementioned handheld part 120 is provided with anti-slip texture, and the end of the handheld part 120 is provided with a hanging hole 121, which conforms to the ergonomic design, making it easy to operate flexibly and easy to store.

[0027] The blade 301 has a mesh pattern on its surface. The mesh pattern can enhance the friction between the blade and the adventitious root, prevent the adventitious root from slipping during cutting, and further improve the cutting accuracy.

[0028] The connecting disc 200 and the tool holder 100 are connected by rivets 230, which is simple and practical.

[0029] The blade 301 has a rounded end, which can prevent the blade 300 from accidentally piercing other roots when it penetrates the culture container.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
