Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural planting equipment, in particular to a plant pruning device for strawberry cultivation. Background Art
[0002] Pruning strawberry plants is an important task in the strawberry planting process. This is because there is a tip effect in plant growth, also known as apical dominance. It is a phenomenon in which the growth of the top of the main stem of the plant is dominant, while inhibiting the growth of the adjacent side buds below it, making the side buds dormant. In order to increase strawberry yield, it is often necessary to prune the tips of strawberry plants.
[0003] Patent publication number CN221653220U provides a strawberry plant pruning device. This solution utilizes a combination of a long tube, a pruning mechanism, and a handle, allowing workers to prune strawberry plants while standing. This avoids frequent bending and standing, alleviating back pain. Furthermore, the strawberry plant pruning device allows for more efficient pruning, saving time and labor. While this solution utilizes a combination of a long tube, a pruning mechanism, and a handle, allowing workers to prune strawberry plants while standing, the tips of the blades fall into the soil, forcing workers to bend over and pick them up, which is inconvenient. The cut tips should be carried away rather than left in the soil, as cut leaf tips or stems can harbor pathogens and pests. If left in the soil, they can spread disease. Summary of the Invention

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.
[0029] The utility model provides a plant pruning device for strawberry cultivation, referring to Figures 1-4 ,include:
[0030] A long pole 1, the top of which is detachably provided with a handle 2;
[0031] A base 4 is detachably fixed to the bottom end of the long pole 1;
[0032] A pair of brackets 5 are slidably connected to the bottom end of the base 4 and are symmetrically arranged; and the lower side of each bracket 5 is equipped with blades 6 arranged opposite to each other;
[0033] A pair of clamping blocks 7 are symmetrically arranged on the upper side of the blade 6; a limit rod 8 is fixed to the ends of the two clamping blocks 7 that are away from each other, the limit rod 8 is movably connected to the bracket 5, and the limit rod 8 is covered by a second spring 9, which is fixed between the bracket 5 and the clamping block 7; and
[0034] The movable component 3 includes a mounting block 33, a rotating rod 34, a lifting rod 35 and a pull rod 31; the two ends of the mounting block 33 are rotatably connected to the rotating rod 34, the other end of the rotating rod 34 is rotatably connected to the bracket 5, and the rotating rod 34 is arranged at an angle; the upper end of the lifting rod 35 passes through the base 4, and the lower end of the lifting rod 35 is externally sleeved with a first spring 36, and the first spring 36 is fixed between the base 4 and the mounting block 33; the pull rod 31 is placed under the handle 2, and the pull rod 31 is slidably connected to the long rod 1, the bottom of the pull rod 31 is fixedly connected to the connecting rope 32, and the connecting rope 32 is fixedly connected to the upper end of the lifting rod 35.
[0035] In this embodiment, the long pole 1 forms the main framework of the entire device and is constructed from a lightweight, high-strength metal material, ensuring both lightness and strength. The handle 2 is detachable and ergonomically designed to ensure a comfortable grip and facilitate user-friendly angle adjustment, enhancing flexibility. The base 4, also constructed from lightweight materials, plugs into and secures to the bottom of the long pole 1. Its primary function is to provide a stable support for the entire device. The bracket 5 at the bottom of the base 4 is symmetrically and slidably connected, offering an adjustable structure that allows the bracket 5 to slide within a certain range. The blade 6 mounted on the underside of the bracket 5 is bolted and removable for easy maintenance. A pair of clamping blocks 7, located above the blade 6 and connected to the bracket 5 via a limit rod 8, ensure that the clamping blocks 7 operate before the blade 6 during the shearing process, firmly gripping the plant tip and preventing it from dislodging. A second spring 9 provides the necessary elastic support for the clamping blocks 7, ensuring smooth operation and avoiding excessive pressure and damage to the plant. The mounting block 33 is linked to the bracket 5 via rotating rods 34 at either end. The tilted design of the rotating rods 34 facilitates force transmission and distribution. A lifting rod 35 extends through the base 4, and a first spring 36 mounted at its lower end provides a rebound force, ensuring the device automatically resets after shearing. The pull rod 31 indirectly controls the movement of the lifting rod 35. The operator simply pulls the nearby pull rod 31 to start and end the shearing and clamping process.
[0036] During use, the operator first grasps the handle 2 and extends the device to the tip of the target strawberry plant, positioning the tip between a pair of clamping blocks 7 and a blade 6. The operator then pulls the pull rod 31 upward, causing it to move upward, driving the connecting rope 32 to pull the lifting rod 35. As the lifting rod 35 moves upward, the first spring 36 is compressed, and the rotating rod 34 is forced to tilt further, causing the bracket 5 to retract inward. At this point, the clamping block 7 first clamps the plant tip. Then, as the bracket 5 continues to approach, the blade 6 cuts in, completing the shearing. The sheared tip is firmly held by the clamping block 7 and will not fall immediately. The operator can then move the clamping block 7 and the tip above the collection container. The operator then releases the pull rod 31, causing the first spring 36 to reset, driving the mounting block 33 to reset, causing the bracket 5 to open and the tip to fall into the collection container for collection. The entire process does not require the operator to bend over, significantly reducing labor intensity.
[0037] Reference Figure 2-Figure 3 Specifically, the spacing between the pair of clamping blocks 7 is slightly smaller than that between the pair of blades 6, ensuring that the clamping blocks 7 can pre-engage and securely hold the plant tip before the shearing operation begins. This pre-clamping mechanism effectively prevents the tip from slipping or splashing due to direct contact with the blades 6 at the moment of shearing, greatly improving shearing accuracy and safety. It also prevents the cut tip from suddenly falling due to gravity, reducing the risk of contamination to the operating environment.
[0038] Specifically, refer to Figure 3 The pair of blades 6 are staggered vertically, providing a more balanced and effective shear force distribution. Compared to a parallel arrangement, the staggered blades 6 create a "sawtooth effect" during the shearing process. When encountering hard or thick stems, the structural integrity of the material is gradually weakened through alternating shears, rather than a single, forceful cut. This approach not only reduces shear resistance and power consumption, but also avoids unnecessary damage to the plant, ensuring a smooth cut and facilitating subsequent plant recovery and regrowth.
[0039] Reference Figure 2 and Figure 3 The pair of clamping blocks 7 are each equipped with an anti-slip pad 10 at their respective ends, preferably made of rubber. The surface of the anti-slip pad 10 typically has special textures or grooves, which significantly increase the friction between the clamping blocks 7 and the plant tissue, preventing slippage even on smooth or wet surfaces. This allows for a more stable grip on the plant tip, ensuring accurate and safe cutting.
[0040] Reference Figure 4The handle 2 is fixed to the long pole 1 by plugging, for example, a special socket or slot is designed at the top of the long pole 1, and the end of the handle 2 is equipped with a corresponding plug or tenon. The two are simply aligned and assembled with a light push, and the process is quick and easy. In order to enhance the stability of the connection, a rubber ring or other anti-slip material can be added at the plug-in point to prevent loosening during vibration.
[0041] Specifically, reinforcing ribs are provided at the connection between the base 4 and the long rod 1, mainly to increase the rigidity and stability of the connection area between the base 4 and the long rod 1, to prevent deformation or breakage during long-term use or when carrying a large load; by structurally reinforcing the connection points, stress concentration can be effectively dispersed, ensuring the reliability and safety of the entire device in various working environments.
[0042] In this embodiment, the connecting rope 32 is made of a high-tenacity fiber material, such as a synthetic fiber material such as polyester, nylon, or Kevlar. High-tenacity fibers are not easily worn or broken, and can maintain their original shape and strength even after repeated pulling for a long time, significantly extending the service life of the connecting rope 32.
[0043] Implementation principle: When pruning strawberry plants, the operator can carry a container for collecting the cut tips. During the pruning process, the user can hold the handle 2 and extend the lower end of the device to the tip of the strawberry plant so that the tip is located between a pair of clamping blocks 7 and a pair of blades 6. Then the user can use his fingers to pull the pull rod 31 upward to move the pull rod 31 upward. The pull rod 31 will pull the connecting rope 32, and then the connecting rope 32 will pull the lifting rod 35 to move upward on the base 4. The lifting rod 35 will squeeze the first spring 36 when moving. The movement of the lifting rod 35 can drive the pair of rotating rods 34 to rotate, thereby forcing the pair of brackets 5 to approach each other. When the pair of brackets 5 approach each other, During the process, a pair of clamping blocks 7 will first clamp the upper part of the plant tip, and as the pair of brackets 5 continue to approach, a pair of limit rods 8 slide on the bracket 5 and squeeze the second spring 9, thereby causing the pair of blades 6 to collide, and the pair of blades 6 will cut off the tip of the plant. Since the pair of clamping blocks 7 have already clamped the tip, the cut tip will not fall off. The user moves the tip clamped by the pair of clamping blocks 7 to the top of the container, and then releases the pull rod 31. Under the elastic force of the first spring 36, the mounting block 33 will be reset, thereby causing the pair of brackets 5 to move away from each other, and then the pair of blades 6 and the pair of anti-slip pads 10 will be opened one after another, causing the plant tip to fall into the container for collection.
[0044] The above are only preferred embodiments of the present invention and do not limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
