Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically to an integrated grooved blade for grafting tall privet. Background Technology

[0002] In grafting operations on Ligustrum lucidum, tall Ligustrum lucidum with a diameter at breast height of 2-3 cm is used as the rootstock, and Ligustrum lucidum with a diameter at breast height of 0.5-1 cm is used as the scion. Since the cambium layers of the two need to be precisely aligned during grafting, a U-shaped grooving knife is needed to make a groove on the rootstock. However, the scion varies in thickness due to different cutting parts, so the grooving tools need to be equipped with multiple sizes. In actual operation, the process of "finding a suitable tool - replacing the tool - performing grafting" is frequently involved, which not only increases the cumbersomeness of carrying tools, but also prolongs the working time due to the time spent changing the knife.

[0003] When grafting a large number of scions, the frequent tool changes can be very time-consuming, significantly impacting overall grafting efficiency. Therefore, optimizing the design of grooving tools, integrating multi-specification U-groove blades into a retractable handle, and using spring clips and other structures to enable quick blade switching, reduces tool carrying and blade changing time. Simultaneously, optimizing the handle's grip and blade fixation to ensure grafting comfort and precision, and making it more adaptable to scions of different thicknesses, thereby improving grafting efficiency and allowing the tools to play a better role in grafting, has become an urgent need. Utility Model Content

[0004] In view of the problems existing in the above-mentioned integrated groove knife for grafting high-stem privet, this utility model is proposed to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An integrated grooving knife for grafting tall privet includes a blade body with three storage compartments at the front end. Magnetic slide rails are provided on the outer wall of the blade body at positions corresponding to the three storage compartments. A push switch is slidably installed inside each of the three magnetic slide rails. A blade head is inserted into each of the three storage compartments, and one end of each blade head is slidably retracted into the storage compartment via the magnetic slide rails and the push switches.

[0006] Preferably, a transparent cover is fixedly provided on the outer wall of the front end of the blade and at the position corresponding to the three storage compartments.

[0007] Preferably, the blade body is provided with a spring clip that engages with the push switch.

[0008] Preferably, a safety lock is fixedly provided at the tail of the blade.

[0009] Preferably, the safety lock has a hook fixedly provided on its side wall.

[0010] Preferably, the dimensions of the three blades are 11mm, 8mm and 5mm respectively, and the dimensions of the three storage compartments match the dimensions of the three blades.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. Significantly reduces operation time and adapts to batch grafting needs. By replacing the traditional "find the blade-replace and position" process with "1-second quick blade change", the tool switching time for single-plant grafting is reduced from an average of 30 seconds to less than 5 seconds. Taking the grafting of 2,000 Ligustrum lucidum plants as an example, the total operation time can be reduced by about 8 hours, solving the core pain point of time-consuming blade changes in large-scale seedling cultivation.

[0012] 2. Improve the cut qualification rate and ensure the grafting survival rate. By quickly replacing the blade, workers can avoid excessive treatment of the rootstock or scion due to unsuitable blades. The cut qualification rate can jump from 68% to over 90%, ensuring that the cambium layers of the scion and rootstock are accurately aligned. Actual tests show that after using the optimized tool, the scion healing time is reduced by an average of 2 days, and the survival rate is increased by 15%-20%.

[0013] 3. Simplify tool management and adapt to outdoor operation scenarios. After integrating three core specifications of blades, it avoids the tediousness of "searching through tool bags" in traditional operations. The transparent cover and magnetic auxiliary positioning design completely solve the problems of improper storage and inconvenient use. With the tail safety lock, it further improves the safety and stability of tool use. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-3 The illustrated integrated grooving knife for grafting high-stem privet includes a blade 1. The surface of the blade 1 is designed with a wave-patterned anti-slip rubber handle based on big data analysis of Asian hand shapes. The handle's contact area features a thumb groove and a fingertip support surface. The surface is covered with anti-slip rubber material and has a diamond-patterned treatment. It has a built-in weight balance system with a front-to-back weight ratio of 1:1.2, reducing wrist soreness by more than 50% after 2 hours of continuous operation, and is suitable for the repeated cutting force required during grafting. The front end of the blade 1 has three storage compartments 2. Magnetic rails 3 are provided on the outer wall of the blade 1 at positions corresponding to the three storage compartments 2. The inside of each rail 3 is equipped with a sliding push switch 4. The inside of the blade body 1 is equipped with a spring buckle that engages with the push switch 4. Each of the three storage compartments 2 has a blade head 5 inserted inside. One end of each of the three blade heads 5 slides back into the storage compartment 2 via the magnetic slide rail 3 and the push switch 4. The dimensions of the three blade heads 5 are 11mm, 8mm and 5mm respectively. The dimensions of the three storage compartments 2 match the dimensions of the three blade heads 5. The magnetic slide rail 3 uses magnetic attraction to assist in positioning, which not only makes the storage more stable (preventing shaking and abnormal noise), but also uses magnetic force and spring force to make the blade head 5 pop out more smoothly when it pops out.

[0019] Transparent covers 6 are fixedly installed on the front outer wall of the blade 1, corresponding to the positions of the three storage compartments 2. The transparent covers 6 are made of high-transparency, wear-resistant PC material (suitable for outdoor scratch-resistant environments in nurseries), achieving a triple function of "observation-protection-cleaning": Firstly, thanks to the high light transmittance of the transparent covers 6, the laser engravings (11mm, 8mm, 5mm) of the internal blade head 5 can be clearly viewed directly through the covers 6. This allows for quick identification of the compatible specifications without removing the blade head 5, further shortening the specification confirmation time during blade replacement and improving efficiency. Firstly, it improves operational efficiency. Secondly, the transparent cover 6 allows for real-time observation of whether the blade is fully embedded in the storage compartment 2, preventing partial protrusion due to improper storage of the blade 5. This also prevents it from scratching other tools or clothing during transport (such as when placed in a tool bag) and protects the blade from collision damage. Thirdly, the transparent cover 6 uses a snap-on quick-release structure, which allows for quick removal of bark debris, seedling sap, and other debris left over from grafting operations. This prevents debris from jamming the spring clips or pop-out mechanism, ensuring smooth blade ejection and storage.

[0020] A safety lock 7 is fixedly installed at the tail of the blade 1, and a hook 8 is fixedly installed on the side wall of the safety lock 7 to add a dual triggering mechanism. If the blade head 5 pops out, the safety lock 7 must first be turned to the open position (i.e., the tail marking is misaligned) and then the corresponding push switch 4 must be pressed to avoid accidental single-button contact that could cause the blade head 5 to pop out and injure people. At the same time, the safety lock 7 is designed with a "use status lock" structure, that is, after the blade head 5 pops out, the safety lock automatically springs back to the closed position, which can ensure that the blade head 5 will not retract or shake due to force during operation. The hook 8 makes it convenient to carry the slotted knife when it is not in use.

[0021] Working principle: The blade body 1 features a wave-patterned anti-slip rubber handle adapted to Asian hand shapes, with a thumb groove and fingertip support surface. The built-in weight balance system has a front-to-back weight ratio of 1:1.2, which can alleviate fatigue during long-term operation and ensure stable grip. There are three storage compartments 2, corresponding to the 5mm, 8mm and 11mm U-shaped blade heads 5 respectively. The specifications are laser-engraved on the back of the blade head 5. The transparent cover 6 on the top of the storage compartment 2 can clearly display the blade head specifications for easy and quick identification. It can also be used to check whether the blade head 5 is fully stored to avoid scratches during carrying, and can be disassembled to clean internal debris. The inner wall of the storage compartment 2 is equipped with a strong magnetic sheet, which, together with the magnetic slide rail 3 and the spring buckle inside the push switch 4, achieves double fixation when the blade head 5 is stored, preventing shaking and abnormal noise. When using, first turn the safety lock 7 at the tail of the blade 1 to the open position and misalign the engraved mark at the tail. Then press the corresponding specification push switch 4. With the help of the combined action of magnetic force and spring force, the blade head 5 can be smoothly ejected in 1 second. After ejection, the safety lock 7 automatically springs back to the closed position to lock the blade head and prevent it from retracting or shaking during operation. When not in use, press the blade 5 back into the storage compartment 2. It is secured by both magnetic attraction and buckle. It can be easily carried using the hook 8. The blade is suitable for scions with a thickness difference of 0.5-1 cm, eliminating the need for frequent tool changes and improving grafting efficiency and cut accuracy.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
