Description

Technical Field

[0001] This utility model relates to the field of flower and fruit thinning technology, specifically a double-edged, center-position blade shearing structure for thinning flowers and fruits of kiwifruit. Background Technology

[0002] Chinese kiwifruit, also known as Yangtao vine, Yangtao, and Yangtao, is a large deciduous vine belonging to the genus Actinidis in the family Actinidiaceae. Young branches of the Chinese kiwifruit tree are pubescent, becoming glabrous or retaining broken remnants of hair as they age. Second-year branches are completely glabrous. Excessive flowering and fruiting disperses nutrient supply, leading to smaller fruits and reduced quality. Thinning flowers and fruits allows the tree to concentrate nutrient supply on the remaining fruits, resulting in larger, fuller fruits with better color and taste, thus increasing the fruit's commercial value.

[0003] Currently, most kiwifruit thinning tools use a single straight blade structure to cut small flower stalks and fruit stalks. When it is necessary to remove fruit branches with a high degree of lignification or thicker perennial branches, the single straight blade has high cutting resistance and is prone to wear, which requires the operator to repeatedly squeeze with force. This is not only inefficient, but may also cause the branches to tear or the flowers and fruits to be damaged due to blade slippage. Therefore, a double-edged, centrally positioned blade cutting structure is needed for kiwifruit thinning. Utility Model Content

[0004] The purpose of this invention is to provide a double-edged, center-position blade shearing structure for thinning flowers and fruits of kiwifruit, which solves the problems mentioned in the background art.

[0005] This application provides a double-edged center blade shearing structure for thinning flowers and fruits of kiwifruit, including a fixing plate. The top of the fixing plate has symmetrical slots on both sides. Each slot has a locking block that engages with it. Each locking block has a longitudinally threaded extension bolt, which is threaded to the fixing plate. A center blade is fixedly connected to the top of each locking block. Each center blade has a comb-tooth cutting edge on its opposite side and a straight cutting edge on its opposite side.

[0006] In use, the slot allows for reversible installation of the locking block, enabling the interchange of the straight cutting edge and comb-tooth cutting edge of the center blade. The locking block is then secured with an extension bolt. The straight cutting edge of the center blade, in conjunction with the upper straight cutting edges of the first and second shearing blades, can precisely cut delicate flower stems. The comb-tooth cutting edge of the center blade, in conjunction with the lower toothed cutting edges of the first and second shearing blades, can efficiently process thick branches through sawing. This allows one tool to handle multiple working conditions, significantly improving the convenience and efficiency of flower and fruit thinning.

[0007] Optionally, the front wall of the fixing plate is rotatably connected to a first handle via a pin, and the rear wall of the fixing plate is rotatably connected to a second handle via the same pin. A first shearing blade is fixedly connected to the top of the first handle, and a second shearing blade is fixedly connected to the top of the second handle.

[0008] By adopting the above technical solution, the first handle and the second handle can drive the first shearing blade and the second shearing blade to rotate respectively, and the shearing operation can be completed in conjunction with the center blade.

[0009] Optionally, a partition frame is fixedly connected to the top of the fixing plate. The partition frame is located between the two center blades and has a U-shaped structure.

[0010] By adopting the above technical solution, the separator can hold the flowers and fruits that need to be retained, thus avoiding damage to the flowers and fruits that need to be retained by the central blade during cutting.

[0011] Optionally, the height of the top end of the extended bolt is lower than the height of the top plane of the fixing plate.

[0012] By adopting the above technical solution, it is beneficial to conceal the installation of the extended bolts without affecting the normal rotation and shearing of the first and second shearing blades.

[0013] Optionally, the center blade is made of stainless steel.

[0014] By adopting the above technical solutions, it is beneficial to improve the strength and corrosion resistance of the center blade and extend its service life.

[0015] Optionally, the lower half of both the first and second shearing blades are toothed edges, which interlock with the comb-tooth edges.

[0016] By adopting the above technical solution, it is beneficial to use the comb-tooth cutting edge of the middle blade to cut thicker fruit tree branches.

[0017] Optionally, a return spring is fixedly connected to both sides of the bottom end of the fixing plate between the first handle and the second handle.

[0018] By adopting the above technical solution, it is beneficial to reset the first handle and the second handle, eliminating the need for operators to manually reset the first handle and the second handle.

[0019] Optionally, the card block and the card slot are compatible.

[0020] By adopting the above technical solution, the stability of the center blade installation can be improved, and shaking can be avoided.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application sets a front straight cutting edge and a rear comb-tooth cutting edge on the middle blade, so that the tool can accurately cut thin and soft flower stems and efficiently process thick branches by sawing. It achieves the goal of one tool to handle multiple working conditions, significantly improving the convenience and efficiency of thinning flowers and fruits. In addition, with the cooperation of extended bolts, locking blocks and locking slots, the middle blade is easy to disassemble and assemble, reducing the difficulty of disassembly and assembly.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a double-edged center blade shearing structure for thinning flowers and fruits of kiwifruit, including a fixed plate 2. The top of the fixed plate 2 is symmetrically provided with slots 13 on both sides. Each slot 13 has a locking block 12 inside it. Each locking block 12 has a longitudinal threaded extension bolt 11. Both extension bolts 11 are threaded to the fixed plate 2. The top of each locking block 12 is fixedly connected with a center blade 9. Each of the two center blades 9 has a comb-tooth cutting edge 8 on one side opposite to each other, and a straight cutting edge 10 on the side opposite to each other.

[0030] In the technical solution of this utility model, such as Figure 1As shown, the front wall of the fixed plate 2 is rotatably connected to the first handle 3 via a pin, and the rear wall of the fixed plate 2 is rotatably connected to the second handle 5 via the same pin. The top end of the first handle 3 is fixedly connected to the first shearing blade 1, and the top end of the second handle 5 is fixedly connected to the second shearing blade 6. The first handle 3 and the second handle 5 can drive the first shearing blade 1 and the second shearing blade 6 to rotate respectively, and can complete the shearing operation in conjunction with the center blade 9.

[0031] In the technical solution of this utility model, such as Figure 1 As shown, a partition frame 7 is fixedly connected to the top of the fixed plate 2. The partition frame 7 is located between the two middle blades 9. The partition frame 7 has a U-shaped structure. The partition frame 7 can put the flowers and fruits that need to be retained into its interior, which can prevent the middle blades 9 from damaging the flowers and fruits that need to be retained during cutting.

[0032] In the technical solution of this utility model, such as Figure 3 As shown, the top height of the extension bolt 11 is lower than the top plane height of the fixing plate 2; this facilitates the concealed installation of the extension bolt 11 and does not affect the normal rotation and shearing of the first shearing blade 1 and the second shearing blade 6.

[0033] In the technical solution of this utility model, not shown, the center blade 9 is made of stainless steel; this is beneficial to improving the strength and corrosion resistance of the center blade 9 and extending its service life.

[0034] In the technical solution of this utility model, such as Figure 1 As shown, the lower half of the first shearing blade 1 and the second shearing blade 6 are both toothed, and the toothed blades interlock with the comb-tooth blades 8; this is beneficial for completing the shearing of thicker fruit tree branches in conjunction with the comb-tooth blades 8 of the middle blade 9.

[0035] In the technical solution of this utility model, such as Figure 1 As shown, both sides of the bottom end of the fixing plate 2 are fixedly connected with a return spring 4 between the first handle 3 and the second handle 5; this facilitates the reset of the first handle 3 and the second handle 5, eliminating the need for the operator to manually reset the first handle 3 and the second handle 5.

[0036] In the technical solution of this utility model, such as Figure 4 As shown, the locking block 12 and the locking slot 13 are compatible; this helps to improve the stability of the installation of the center blade 9 and avoids shaking.

[0037] In use, the card slot 13 allows for the reverse installation of the card block 12, thereby allowing the position of the straight cutting edge 10 and the comb-tooth cutting edge 8 of the center blade 9 to be interchanged. Then, the card block 12 can be fixed by the extension bolt 11. The straight cutting edge 10 of the center blade 9, in conjunction with the upper half of the straight cutting edge surface of the first shearing blade 1 and the second shearing blade 6, can accurately cut thin and soft flower stems. The comb-tooth cutting edge 8 of the center blade 9, in conjunction with the lower half of the toothed cutting edge surface of the first shearing blade 1 and the second shearing blade 6, can efficiently process thick branches by sawing. This achieves the goal of using one tool to handle multiple working conditions, significantly improving the convenience and efficiency of thinning flowers and fruits.
