Description

Technical Field

[0001] This utility model belongs to the field of tender shoot harvesting technology, specifically relating to a harvesting device for thorny wild woody vegetables. Background Technology

[0002] Aralia elata (also known as spiny buds, thorny shoots, or thorny five-spice) is a deciduous shrub or small tree widely distributed in mountain forests. Its spring-sprouting tender shoots (commonly known as spiny shoots) are a distinctive seasonal wild vegetable, bright green in color, tender in texture, and rich in various vitamins, minerals, and unique active ingredients, possessing high nutritional and health value. In recent years, due to its unique flavor and health benefits, the demand for Aralia elata shoots has been increasing in the market, making it an important by-product of economic forestry and a source of specialty food. Therefore, timely and efficient harvesting of Aralia elata shoots is a key step in realizing its economic value.

[0003] However, Aralia elata plants (especially the branches and trunks) are typically covered with hard, sharp thorns (skin thorns or branch thorns). In the currently common manual harvesting method, operators need to reach directly into the dense foliage with their hands or simple tools (such as scissors) to find, grasp, and pinch or cut off the tender buds at the branch tips. During this process, the operator's hands and forearms inevitably come into contact with or traverse areas covered in thorns. The thorns on Aralia elata are not only dense but also sharp, easily scratching and piercing the operator's skin, leading to wounds, pain, and even the risk of infection. This not only directly affects the safety and health of harvesters, reducing their comfort and motivation, but also significantly reduces harvesting efficiency and increases labor costs due to the need to treat wounds or replace personnel after injury. This has become a prominent technical challenge restricting the large-scale, efficient harvesting of Aralia elata buds. Therefore, we propose a harvesting device for thorny wild woody vegetables to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a method that can reduce the risk of hand injuries to harvesters when picking Aralia elata buds and improve harvesting efficiency.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A harvesting device for thorny wild woody vegetables includes a stationary blade and a moving blade rotatably connected at their ends, and a fixed rod and a force-bearing rod respectively fixedly installed on the stationary blade and the moving blade. An extension rod is fixedly installed at the end of the fixed rod, and an adapter is provided at the end of the force-bearing rod. A sliding groove is provided on the extension rod, and a slider is slidably installed in the sliding groove. A rotating rod is provided between the slider and the adapter, and the rotating rod is rotatably connected to the slider. A drive mechanism is provided on the force-bearing rod to pull the slider to move in the sliding groove.

[0007] Further specifying, the drive mechanism includes a take-up reel, a pull rope, and a drive component that drives the take-up reel to rotate. The extension rod has a mounting groove communicating with the slide rail. The take-up reel is rotatably mounted in the mounting groove. The pull rope is fixedly connected between the take-up reel and the slider. The drive component is mounted on the extension rod. With this structural design, when the take-up reel rotates, the pull rope can pull the slider, thereby driving the stationary and moving blades to complete the shearing operation.

[0008] Further specifying, the driving component includes a fixed base and a mounting base fixedly mounted on the extension rod, a rotating handle rotatably mounted on the fixed base, a drive gear, and a movable rod. A fixed shaft is fixedly mounted at the center of the take-up reel, with both ends of the fixed shaft passing through the extension rod. The drive gear is fixedly mounted at the end of the fixed shaft near the mounting base. A limiting groove is formed on the mounting base, and the movable rod is movably mounted within the limiting groove. A groove is formed on the movable rod, and a rack is fixedly mounted within the groove. The rack meshes with the drive gear. The movable rod is L-shaped, and a collar is fixedly mounted at its end, which is fitted onto the end of the rotating handle. This structural design allows the rotating handle, in conjunction with the movable rod, to drive the drive gear and the take-up reel to rotate, facilitating the movement of the slider.

[0009] Furthermore, a return spring is fixedly installed between the rotating handle and the extension rod. This structural design allows the return spring to provide an elastic restoring force to the rotating handle, enabling it to return to its initial state when no external force is applied.

[0010] Furthermore, a tension spring is fixedly installed between the slider and the groove wall near the fixed rod. This structural design allows the tension spring to move the slider when the driving mechanism releases the tension on the slider, returning it to its initial state. This maintains a certain angle between the stationary and moving blades, facilitating subsequent use.

[0011] Further specifying, the adapter includes a sleeve, a threaded seat fixedly mounted on the sleeve and communicating with the inside of the sleeve, a locking bolt threaded onto the threaded seat, and a fixing post fixedly mounted on the sleeve. The sleeve is movably fitted onto the force-bearing rod, and the fixing post is rotatably connected to the end of the rotating rod away from the slider. This structural design is simple and easy to use.

[0012] The utility model adopting the above technical solution has the following advantages:

[0013] This invention incorporates a drive mechanism and an extension rod, enabling the harvesting device to perform both static and dynamic cutting operations with a single hand grip. This not only allows for the cutting of tender aralia elata buds at higher elevations but also prevents scratches from the thorns on the buds during harvesting, thus improving harvesting efficiency.

[0032] like Figures 1-6 As shown, this utility model discloses a harvesting device for thorny wild woody vegetables, including a stationary blade 1 and a moving blade 2 rotatably connected at their ends, and a fixed rod 11 and a force-bearing rod 21 respectively fixedly installed on the stationary blade 1 and the moving blade 2. An extension rod 3 is fixedly installed at the end of the fixed rod 11. The end of the extension rod 3 away from the stationary blade 1 is covered with a rubber anti-slip sleeve, which can increase the friction between the hand and the extension rod 3 and enhance the grip comfort. A connector 22 is provided at the end of the force-bearing rod 21. A groove 31 is opened on the extension rod 3. A slider 32 is slidably installed in the groove 31. A tension spring 7 is fixedly installed between the slider 32 and the groove wall of the groove 31 near the fixed rod 11. A rotating rod 33 is provided between the slider 32 and the connector 22. The rotating rod 33 is rotatably connected to the slider 32. A drive mechanism is provided on the force-bearing rod 21 to pull the slider 32 to move in the groove 31.

[0033] The drive mechanism includes a take-up reel 4, a pull rope 41, and a drive component that drives the take-up reel 4 to rotate. The extension rod 3 has a mounting groove that communicates with the slide groove 31. The take-up reel 4 is rotatably mounted in the mounting groove. The pull rope 41 is fixedly connected between the take-up reel 4 and the slider 32. The drive component is set on the extension rod 3.

[0034] The driving component includes a fixed base 5 and a mounting base 51 fixedly mounted on the extension rod 3, a rotating handle 52 rotatably mounted on the fixed base 5, a drive gear 53, and a movable rod 54. A return spring 6 is fixedly installed between the rotating handle 52 and the extension rod 3. A fixed shaft is fixedly installed at the center of the winding wheel 4. Both ends of the fixed shaft pass through the extension rod 3. The drive gear 53 is fixedly installed at one end of the fixed shaft near the mounting base 51. A limit groove is provided on the mounting base 51. The movable rod 54 is movably installed in the limit groove. A groove is provided on the movable rod 54. A rack 541 is fixedly installed in the groove. The rack 541 meshes with the drive gear 53. The movable rod 54 is L-shaped, and a collar 55 is fixedly installed at the end of the movable rod 54. The collar 55 is sleeved on the end of the rotating handle 52.

[0035] The adapter 22 includes a sleeve 221, a threaded seat 222 fixedly installed on the sleeve 221 and communicating with the inside of the sleeve 221, a locking bolt 223 threadedly connected to the threaded seat 222, and a fixing post 224 fixedly installed on the sleeve 221. The sleeve 221 is movably fitted onto the force-bearing rod 21. When the sleeve 221 is fitted onto the force-bearing rod 21, the locking bolt 223 is turned until its end abuts against the force-bearing rod 21. At this time, the adapter 22 will be locked onto the force-bearing rod 21. This locking position can be adjusted according to the opening and closing angle of the stationary blade 1 and the moving blade 2. The fixing post 224 is rotatably connected to the end of the rotating rod 33 away from the slider 32.

[0036] The method of using this utility model is as follows:

[0037] When in use, the harvester can hold the extension rod 3 with one hand and control the stationary blade 1 at the end of the extension rod 3 to be close to the target bud, so that the bud is located between the stationary blade 1 and the moving blade 2. Then, the harvester can use the fingers holding the extension rod 3 to hook the rotating handle 52 to rotate. The moving rod 54 moves vertically downward under the drive of the rotating handle 52. At this time, the rack 541 drives the winding wheel 4 to rotate through the drive gear 53. The winding wheel 4 winds up the pull rope 41, so that the slider 32 slides in the groove 31 towards the winding wheel 4.

[0038] When the slider 32 slides, the rotating rod 33 and the adapter 22 drive the force rod 21 to rotate, causing the moving blade 2 to close to the stationary blade 1, and cooperate with the stationary blade 1 to cut the tender bud. During the cutting process, the picker can place his other hand under the tender bud to catch it.

[0039] After the cutting is completed, the fingers release the force on the rotating handle 52, and the slider 32 and the rotating handle 52 will return to their initial state under the elastic force of the tension spring 7 and the return spring 6, respectively, so as to facilitate subsequent use.

[0040] The above provides a detailed description of a harvesting device for thorny wild woody vegetables provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
