Description

Technical Field

[0001] This utility model relates to the field of horticultural technology, and more specifically, to an improvement of a fruit-picking shear to prevent fruit drop. Background Technology

[0002] In traditional fruit harvesting, ordinary fruit shears only have the single function of cutting the vines. Once the vines are cut, the fruit loses its support and falls freely. This is especially problematic for soft, ripe fruits like grapes and cherries; the fruit is easily damaged and rots upon impact with the ground or other objects, severely impacting its quality and market value. Furthermore, for fruits growing at higher elevations, falling fruit can cause accidental injuries to workers below. Although some existing harvesting tools attempt to incorporate support structures to prevent fruit from falling, these structures generally suffer from unstable support, cumbersome operation, and low harvesting efficiency. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a fruit-picking shear with a vine-locking and fruit-fall-preventing function. This shear can reliably lock the vine while cutting it, preventing the fruit from falling. Furthermore, it features a reasonable structural design, is easy to operate, and can improve harvesting efficiency, meeting the actual needs of horticultural harvesting. This solves the problems of existing harvesting tools that attempt to add a support structure to prevent fruit from falling, but these structures generally suffer from unstable support, cumbersome operation, and low harvesting efficiency.

[0005] (II) Technical Solution

[0006] To achieve the advantages of reliably securing the fruit vine while cutting it, preventing the fruit from falling, and with a reasonable structural design, convenient operation, and improved harvesting efficiency to meet the actual needs of horticultural harvesting, the specific technical solution adopted by this utility model is as follows: It includes a fixed blade, a moving blade, and a supporting clamping block. The fixed blade, moving blade, and supporting clamping block are hinged together. The supporting clamping block is fastened to the fixed blade with screws. The moving blade is equipped with a spring seat, a clamping tooth block, a fixing screw, and a limiting screw. The spring seat is bolted to the back of the moving blade. The clamping tooth block is connected to the other side of the moving blade via the fixing screw and the limiting screw. A gap is left between the clamping tooth block and the moving blade. The clamping tooth block has a pointed tooth structure. A fixed shaft and a travel groove are provided inside the clamping tooth block. The spring of the spring seat is connected to the fixed shaft. The limiting screw is adjusted within the travel groove and connected to the clamping tooth block. The supporting clamping block opens and closes below the clamping tooth block.

[0007] Furthermore, the moving blade has a wire hole that connects to the fixing wire and the limiting wire.

[0008] Furthermore, the clamping block is a U-shaped component with a through hole at the top and multiple slots on both sides, through which the spring passes and is connected to the fixed shaft.

[0009] Furthermore, the spring seat is vertically connected to the moving blade.

[0010] Furthermore, the upper end of the support clamping block is provided with teeth that cooperate with the clamping tooth block.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, this utility model provides a fruit-picking shear with anti-drop properties for vines, which has the following beneficial effects:

[0013] It uses the cooperation of clamping teeth and supporting clamping blocks to quickly clamp the fruit vines while cutting them, preventing the fruit from falling and greatly reducing damage caused by fruit falling. This effectively protects fruit quality and reduces economic losses.

[0019] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0020] According to an embodiment of this utility model, a fruit-picking shear with anti-dropping properties for vines is provided.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3 As shown, a fruit-picking shear with anti-drop properties according to an embodiment of the present invention includes a fixed blade 1, a movable blade 3, and a support clamping block 5. The fixed blade 1, the movable blade 3, and the support clamping block 5 are hinged together. The support clamping block 5 is fastened to the fixed blade 1 by screws. The movable blade 3 is provided with a spring seat 4, a toothed block 2, a fixing screw 6, and a limiting screw 7. The spring seat 4 is bolted to the back of the movable blade 3. The toothed block 2 is connected to the other side of the movable blade 3 by the fixing screw 6 and the limiting screw 7. There is a gap between the toothed block 2 and the movable blade 3. The toothed block 2 has a pointed tooth structure. The toothed block 2 has a fixed shaft 21 and a travel groove 22 inside. The spring 41 of the spring seat 4 is connected to the fixed shaft 21. The limiting screw 7 is adjusted in the travel groove 22 and connected to the toothed block 2. The support clamping block 5 opens and closes below the toothed block 2. The limiting wire 7 is installed in the stroke groove 22 and connected to the clamping tooth block 2. By adjusting the position of the limiting wire 7 in the stroke groove 22, the movement stroke and angle of the clamping tooth block 2 can be controlled, thereby adapting to the clamping needs of fruit vines of different thicknesses.

[0022] In one embodiment, the moving blade 3 has a wire hole 11 that connects to the fixing wire 6 and the limiting wire 7.

[0023] In one embodiment, the clamping block 2 is a U-shaped component with a through hole at the top and a series of slots on both sides. The spring 41 passes through the through hole and is connected to the fixed shaft 21.

[0024] In one embodiment, the spring seat 4 is vertically connected to the moving blade 3.

[0025] In one embodiment, the upper end of the support clamping block 5 is provided with teeth that cooperate with the clamping tooth block 2. When the moving blade 3 moves, it drives the clamping tooth block 2 to move. The support clamping block 5 cooperates with the clamping tooth block 2, which can reliably clamp the fruit vine after it is cut, preventing the fruit from falling. At the same time, the moving blade 1 is provided with wire holes 11 that connect to the fixing wire 6 and the limiting wire 7, ensuring the stability of the connection between the clamping tooth block 2 and the moving blade 3.

[0026] Working Principle: When using this fruit-picking shears, hold the handle so that the moving blade 3 is open relative to the fixed blade 1. Align the fixed blade 1, moving blade 3, and support clamp 5 with the fruit vine, and firmly grip the handle. The moving blade 3 will rotate around the hinge point toward the fixed blade 1 under the action of the handle. During the rotation of the moving blade 3, since the spring 41 is connected to the fixed shaft 21 of the clamping block 2, the tension of the spring 41 drives the clamping block 2 to rotate around the fixed wire 6, and the clamping block 2 gradually moves toward the fruit vine. When the blades of the moving blade 3 and the fixed blade 1 contact the fruit vine, they work together to cut the fruit vine. At the moment the fruit vine is cut, the spring 41 continues to exert force, causing the clamping block 2 to further clamp the fruit vine. At the same time, the support clamp 5 moves upward under the action of the moving blade 3, and its upper teeth cooperate with the clamping block 2 to firmly clamp the fruit vine and prevent the fruit from falling. At this time, the fruit and the fruit vine can be removed from the fruit-picking shears together, completing the harvesting process. To harvest again, release the handle, and the moving blade 3 will return to its original position under the action of the spring. The clamping block 2 and the support clamping block 5 will also open, allowing the harvesting operation to be repeated.
