Description

Technical Field

[0001] This utility model relates to the field of vegetable harvesting, specifically to a vegetable planting and harvesting tool. Background Technology

[0002] There are many kinds of vegetables, some hanging on tree branches and some growing on the ground. Picking and harvesting vegetables requires walking to the vicinity of the target vegetable and reaching out, bending over or squatting down to pick them one by one. In order to reduce the pressure of picking vegetables and make the picking work easier, many auxiliary tools have emerged. The handle with a gripper can hold vegetables or fruits from a distance and pick them off. Currently, the opening and closing of the gripper is generally driven by a spring. The spring can open and close the gripper with its own return effect. However, the gripper needs to be in different tilt positions when gripping and releasing, and when gripping vegetables of different sizes. The spring component does not have a fixing effect, which makes the stability of this type of tool insufficient and its adaptability limited. Therefore, a vegetable planting and harvesting tool is provided. Utility Model Content

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a vegetable planting and harvesting tool, combined with the attached... Figure 1-2 The present invention includes: a grip bar with a handle at the top, the grip bar adopting a telescopic rod structure, and a support rod 1 and a sleeve 2 with their ends opening and closing respectively at the top and bottom, the support rod 1 and the sleeve 2 both adopting a hollow rod structure; Using a gripping tool to grab and pick vegetables, such as cabbage, eggplant, and peppers, the handle in this application is a telescopic rod. A telescopic rod is a common component, consisting of two or more rods of different diameters stacked together. The ends are equipped with clasps and buckles. After extending or shortening, the length is fixed by locking. Using a telescopic gripping tool here makes it convenient to touch and effectively pick individual vegetables that are high up or protruding from grass. The top of the gripper is connected to a carrier plate 14. The gripper uses multiple clamping rods 15, the bottom of which are evenly distributed and connected to the edge of the carrier plate 14 in a rotating manner. The clamping rods 15 adopt a V-shaped rod structure. Within a certain range, the V-shaped clamping rods 15 have a good clamping effect on vegetables of different sizes. After they are closed together, the ends form a support part, which makes it difficult for the vegetables to fall off during the clamping and transportation process. As shown in the attached drawings provided in this application, the clamping rods 15 are three in number and are evenly distributed with the gripping rod as the center. This is beneficial for picking fruit-type vegetables such as cabbage and eggplant. If the vegetables are flat, such as rapeseed and yam, their specifications can be changed in production and the clamping rods 15 can be arranged on both sides of the carrier plate 14. The carrier plate 14 can also be set in a square or long strip shape. Combined with appendix Figure 3-5 The top of the gripping rod is equipped with a threaded opening and closing assembly that enables the gripper to grasp vegetables by rotating the clamping rod 15. The threaded opening and closing assembly includes an annular support 11 arranged on the outside of the support rod 1 and capable of moving up and down. A drive rod 13 is rotatably connected between the support 11 and the bottom of the clamping rod 15. The support 11 supports the bottom end of the drive rod 13. The drive rod 13, the bottom of the clamping rod 15, and the top of the support rod 1 form a triangular structure. The ends of the three are connected by rotation. When the support 11 moves on the support rod 1, the length of one side of the triangle where the top of the support rod 1 is located changes, thereby causing the tilt angle of the clamping rod 15 to change accordingly. The distance between the tops of the clamping rods 15 increases or decreases, thereby achieving the clamping of vegetables or releasing them from the clamping area. Combined with appendix Figure 6 and attached Figure 8 The support rod 1 is equipped with a lifting assembly that carries the support 11 to move. The lifting assembly includes a support column 7 rotatably connected to the support rod 1. A screw rod 9 is connected to the top of the support column 7. A threaded sleeve 10 connected to the support 11 is threadedly connected to the screw rod 9. A limiting mechanism that prevents the threaded sleeve 10 from rotating is connected between the support rod 1 and the support 11. The limiting mechanism includes multiple slide rails 12 at the top of the support rod 1. Multiple connecting rods that are embedded in the slide rails 12 and maintain mutual sliding connection with the support rod 1 are connected between the threaded sleeve 10 and the support 11. Under the limiting conditions provided by the connecting rod embedded in the slide rail 12, the screw 9 rotates, causing the threaded sleeve 10 connected to the screw 9 to move along with the support 11. Since the threaded sleeve 10 and the screw 9 are connected by a threaded structure, their overall state has a locking function. Therefore, the state of the clamping rod 15 will not change without external interference, so that the effective clamping and bearing of the vegetables can always be maintained during the transportation process. The bottom of the grip is equipped with a drive assembly that causes the support column 7 to rotate, in conjunction with the attached... Figure 7 The drive assembly includes a rotating shaft 4 rotatably connected to the bottom end of the sleeve 2. The bottom end of the rotating shaft 4 extends to the outside of the grip and is connected to a knob 3. A hollow column 5 is connected to the top end of the rotating shaft 4. A sliding groove 8 is provided inside the bottom of the support column 7. Figure 9 The hollow column 5 has a through groove 8 and a guide rod 6 that is slidably connected to the support column 7 at its top end; Since the grip is extendable, and for ease of operation, the knob 3 is positioned near the operator. To accommodate the extendability of the grip and ensure that the knob 3 remains in the same position while still allowing for rotational control of the support column 7, a hollow column 5 is added inside the sleeve 2 as an extension of the bottom of the support column 7. A through hole is pre-drilled at the position of the support column 7 corresponding to the retracted position of the support rod 1, forming a groove 8. A guide rod 6 is horizontally connected to the top of the hollow column 5 and embedded in the groove 8. This allows the hollow column 5 to rotate under the guidance of the knob 3. Through the pushing and pulling action of the guide rod 6, the support column 7 and the screw 9 also rotate synchronously with the hollow column 5, effectively controlling the opening and closing of the clamping rod 15.

[0026] In the specific implementation of this utility model, the vegetables to be picked are taken as the target individuals, and the decision is made on whether to extend the grip on the pole based on the distance between them; Holding the bottom of the handle, bring the picking end containing the clamping rod 15 close to the vegetable. Depending on the size of the target vegetable, first rotate the knob 3 at the end of the handle to open the clamping rod 15 appropriately. Then move the tool forward to make the vegetable fit in the clamping area between the clamping rods 15. Then rotate the knob 3 in the opposite direction until the clamping rod 15 clamps the vegetable. At this time, the clamping rod 15 will not loosen due to the threaded connection between the screw 9 and the screw sleeve 10. Then, use appropriate force to pull the vegetable off, separating it from its mother plant, and then move it back. Finally, turn knob 3 to reopen clamp 15 and release the clamped vegetable.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
