Description

Technical Field

[0001] This utility model relates to the field of leaf trimming technology, specifically a citrus leaf trimming device. Background Technology

[0002] In the planting and maintenance of citrus trees, proper pruning of leaves is a crucial task. Appropriate pruning not only improves ventilation and light penetration within the tree canopy, reducing the occurrence of pests and diseases, but also regulates nutrient distribution, promotes fruit growth and development, and increases the yield and quality of citrus fruits.

[0003] Currently, there are various leaf trimmers on the market. For example, a leaf trimmer with publication number CN218680291U includes a support rod, a rotating rod rotatably mounted at one end of the support rod, and a first hollow rod rotatably mounted at the other end of the rotating rod. A movable rod is located inside the first hollow rod, and a motor is mounted at the end of the movable rod. A blade is mounted at the end of the motor's output shaft. A threaded groove is formed inside the movable rod, and a threaded rod is threadedly connected within the groove. The end of the threaded rod away from the blade is fixedly connected to the rotating rod. Limiting grooves are formed on both sides of the inner wall of the first hollow rod, and limiting blocks are installed within these grooves. The ends of the limiting blocks are connected to the outer surface of the movable rod. A protective cover is provided on the outside of the blade. This design allows the movable rod to extend and retract by rotating the first hollow rod, adjusting the blade height for convenient trimming of trees at height. It also offers high trimming efficiency. The protective cover can cover the blade when not in use, preventing accidental damage during transport and ensuring high safety.

[0004] However, the aforementioned existing technologies still have some shortcomings in practical applications. On the one hand, the process of disassembling and assembling the pruning blades is relatively cumbersome, making it inconvenient to regularly maintain, replace, or clean the blades. When the blades are worn, damaged, or need to be replaced with different specifications to adapt to different pruning needs, the operation is inconvenient, affecting the efficiency and effectiveness of the pruning work. On the other hand, while some height adjustment can be achieved, the operation is not convenient and flexible enough, making it difficult to quickly and accurately adjust the pruning device to the appropriate pruning height. Especially under different growth stages, different varieties of citrus trees, and different pruning scenarios, the requirements for pruning height vary, and the existing technology cannot meet diverse pruning needs.

[0012] Optionally, the top of the side of the support cylinder is threaded with a fixing bolt for positioning the adjusting slide rod, and the side of the adjusting slide rod is provided with a plurality of fixing grooves that match the fixing bolt.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a fixed frame to hold the branch to be pruned. The electric cylinder drives the abutment block to cooperate with the pruning shears, which can quickly and efficiently complete the pruning. Loosening the fixing bolts allows the adjusting slide rod to slide in the support cylinder. After adjustment, tightening can accurately fix the cutting height of the pruning component to meet various pruning needs. Loosening the fixing nut allows for easy disassembly and removal of the pruning shears, which is convenient for replacement, maintenance and cleaning, ensuring the device is in good working condition, extending its service life and reducing costs. It provides an efficient, convenient and flexible tool for pruning citrus trees.

[0014] 2. Convenient Pruning Function: In actual use, the operator only needs to accurately clamp the fixing frame onto the branch to be pruned, and then activate the electric cylinder, which drives the abutment block to move. The interaction between the abutment block and the pruning shears allows for quick and effective pruning of the branches. This design makes pruning operations simpler and more direct, greatly improving pruning efficiency, and is especially suitable for pruning large areas of citrus trees, saving labor and time costs.

[0015] 3. Convenient Adjustment of Pruning Height: When the cutting height of the pruning component needs to be adjusted according to different pruning requirements, the operator only needs to loosen the fixing bolt, disengaging it from the corresponding fixing groove on the side of the adjusting slide rod. At this time, the adjusting slide rod can slide freely on the inner wall of the support cylinder, allowing the operator to adjust it to the appropriate position according to the actual situation. After adjustment, tighten the fixing bolt, ensuring it is securely locked in the corresponding fixing groove, thus achieving precise fixing of the pruning component's cutting height. This design makes the adjustment of pruning height simple and quick, meeting the diverse requirements for pruning height at different growth stages, for different varieties of citrus trees, and in different pruning scenarios.

[0016] 4. Easy disassembly and assembly of the trimmer shears: When the trimmer shears need to be replaced, maintained, or cleaned, the operator only needs to loosen the fixing nut. Since the trimmer shears are fixed to the frame by the mounting bolts and fixing nuts, they can be easily removed from the frame after loosening the fixing nut. Similarly, installing new trimmer shears is also very simple; just align the trimmer shears with the corresponding position on the frame using the mounting bolts, and then tighten the fixing nut. This detachable design facilitates the replacement and maintenance of the trimmer shears, ensuring that the trimming device is always in good working condition, extending the service life of the equipment, and reducing operating costs.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6 A citrus leaf pruning device is disclosed, which mainly consists of a pruning component 1 for pruning citrus tree leaves and an adjustable grip component 2 installed at the bottom of the pruning component 1. This structural design enables the entire pruning device to not only have efficient pruning function, but also to allow operators to easily adjust the grip and height according to actual needs, so as to adapt to citrus tree leaf pruning work in different scenarios.

[0021] To achieve precise and efficient pruning of citrus tree leaves, in this embodiment, the pruning component 1 includes a fixed frame 101, on which a detachable pruning shear 1011 is mounted. The bottom of the pruning shear 1011 is equipped with a movable abutment block 1012 that works in conjunction with the pruning shear 1011. Through this unique structural design, during pruning, the abutment block 1012 and the pruning shear 1011 work together to quickly and accurately cut the leaves, greatly improving pruning efficiency and quality. Simultaneously, the detachable pruning shear 1011 facilitates subsequent maintenance, replacement, and cleaning, extending the equipment's lifespan and reducing operating costs.

[0022] To facilitate quick assembly and disassembly of the trimmer scissors 1011, adapting to replacement needs of different specifications or for routine maintenance, in this embodiment: two symmetrically arranged mounting bolts 102 are fixedly connected to the top of the trimmer scissors 1011. The top of the mounting bolts 102 extends through the fixing frame 101 and outwards, and the mounting bolts 102 are fixedly mounted to the fixing frame 101 by fixing nuts 1021. When it is necessary to disassemble the trimmer scissors 1011, simply loosen the fixing nuts 1021 to remove the trimmer scissors 1011 from the fixing frame 101; during installation, align the trimmer scissors 1011 with the corresponding holes on the fixing frame 101 via the mounting bolts 102, and then tighten the fixing nuts 1021 to complete the installation. This installation method is simple, convenient, and quick, greatly improving work efficiency.

[0023] To ensure the stability of the abutment block 1012 during lifting and lowering, and to enable it to accurately cooperate with the trimmer scissors 1011 to complete the trimming action, in this embodiment: a limiting slider 103 is fixedly connected to the side of the abutment block 1012, and a limiting groove 1031 matching the limiting slider 103 is provided on the side of the inner wall of the fixing frame 101. During the lifting and lowering of the abutment block 1012, the limiting slider 103 slides within the limiting groove 1031, effectively preventing the abutment block 1012 from shifting in the horizontal direction, ensuring the relative positional accuracy between the abutment block 1012 and the trimmer scissors 1011, thereby improving the accuracy and stability of trimming.

[0024] To achieve automatic lifting and lowering of the abutment block 1012, thereby cooperating with the pruning shears 1011 to complete automated pruning, in this embodiment: an electric cylinder 104 for driving the lifting and lowering of the abutment block 1012 is installed at the bottom of the inner wall of the fixed frame 101, and the output end of the electric cylinder 104 is fixedly connected to the bottom of the abutment block 1012. Through the extension and retraction movement of the electric cylinder 104, the lifting height and speed of the abutment block 1012 can be precisely controlled, enabling the pruning of leaves of different thicknesses and hardness. This electric drive method not only improves pruning efficiency but also reduces the labor intensity of operators, making pruning work easier and more convenient.

[0025] To facilitate operator gripping of the pruning device and allow for height adjustment of the pruning component 1 according to different pruning height requirements, in this embodiment, the gripping component 2 includes a support cylinder 201. An adjusting rod 2011 is slidably mounted on the inner wall of the support cylinder 201, and the top of the adjusting rod 2011 is fixedly connected to the bottom of the fixed frame 101. Operators can adjust the sliding position of the adjusting rod 2011 within the support cylinder 201 to change the height of the pruning component 1, adapting to pruning work on citrus tree leaves of different heights. This adjustable gripping component 2 design improves the versatility and practicality of the device.

[0026] To ensure the stability of the adjusting slide bar 2011 when sliding within the support cylinder 201 and to prevent it from wobbling or shifting during the sliding process, in this embodiment, a positioning slider 202 is fixedly connected to the bottom of the adjusting slide bar 2011, and a positioning groove 2021 matching the positioning slider 202 is provided on the inner wall of the support cylinder 201. During the sliding process of the adjusting slide bar 2011, the positioning slider 202 slides within the positioning groove 2021, providing a stable guiding effect for the adjusting slide bar 2011, ensuring the smoothness and accuracy of the sliding of the adjusting slide bar 2011, thereby improving the stability and reliability of the entire grip assembly 2.

[0027] To ensure the adjusting slide bar 2011 is securely fixed after sliding to the desired position, thus maintaining the stable height of the trimming assembly 1, in this embodiment: a fixing bolt 203 for positioning the adjusting slide bar 2011 is threadedly connected to the top of the side of the support cylinder 201. Several fixing grooves 2031, matching the fixing bolt 203, are provided on the side of the adjusting slide bar 2011 at positions corresponding to the fixing bolt 203. Once the adjusting slide bar 2011 has slid to the desired height, the operator simply tightens the fixing bolt 203, causing it to engage with the corresponding fixing groove 2031, thus securely fixing the adjusting slide bar 2011 within the support cylinder 201, thereby ensuring the stability of the trimming assembly 1 during operation. This fixing method is simple to operate, reliable, and can meet the needs of different height adjustments.

[0028] In use, the operator first accurately clamps the fixing frame 101 onto the branch to be pruned, ensuring that the pruning shears 1011 and the abutment block 1012 are in the appropriate working position. Then, the electric cylinder 104 is activated, and the output end of the electric cylinder 104 pushes the abutment block 1012 upward. Under the limiting action of the limiting slider 103 and the limiting groove 1031, the abutment block 1012 rises steadily and cooperates with the pruning shears 1011 to achieve convenient pruning of the branch.

[0029] When the cutting height of the pruning component 1 needs to be adjusted according to the different heights of citrus tree leaves, the operator loosens the fixing bolt 203, causing it to disengage from the corresponding fixing groove 2031 on the side of the adjusting slide rod 2011. Then, the adjusting slide rod 2011 slides smoothly on the inner wall of the support cylinder 201, and under the positioning action of the positioning slider 202 and the positioning groove 2021, the adjusting slide rod 2011 slides smoothly. After adjustment, the fixing bolt 203 is tightened, causing it to engage in the corresponding fixing groove 2031, thus achieving precise adjustment of the cutting height of the pruning component 1.

[0030] Meanwhile, when the pruning shears 1011 need to be replaced, simply loosen the fixing nut 1021 to remove the pruning shears 1011 from the fixing frame 101, which is convenient and quick. The entire device has a reasonable structure, is simple to operate, and can efficiently and stably complete the pruning of citrus tree leaves.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
