Description
Technical Field
[0001] This invention relates to the field of pruning technology, specifically to a pruning device for fruit tree cultivation. Background Technology
[0002] Pruning is a crucial aspect of fruit tree cultivation and management, directly impacting ventilation and light penetration, nutrient distribution efficiency, and the final quality and yield of the fruit. Regular, precise pruning of overly dense branches, vigorous shoots, and diseased or weak branches is essential to ensure healthy tree growth. However, existing fruit tree pruning devices have several shortcomings in practical application, failing to meet the demands for efficient and convenient pruning.
[0003] Firstly, disassembly and maintenance are inconvenient. Traditional trimming devices often use fixed welding or multiple sets of bolts to connect the blade assembly and the main support structure. When the blades wear out and need to be replaced, or when internal parts need to be repaired, multiple connecting parts need to be disassembled with special tools. This operation is cumbersome and time-consuming, which seriously affects the efficiency of trimming operations.
[0004] Secondly, the driving and pruning precision is insufficient. Some devices rely on manual pressing and swinging to achieve shearing, which can easily lead to hand fatigue for operators after long periods of operation, and it is difficult to accurately control the shearing force and angle. For thicker branches or densely growing branches, problems such as incomplete pruning, uneven branch breakage, and even the accidental pruning of healthy branches often occur, affecting the subsequent growth of fruit trees.
[0005] Third, the device has poor adaptability to different scenarios. The overall length of the existing device is mostly fixed, which makes it impossible to flexibly adjust the working radius according to the height of the fruit tree (such as dwarf fruit trees and tall fruit trees) and the growth position of the branches (such as branches at high positions and branches deep in the canopy). Operators need to move frequently and even use auxiliary tools such as ladders, which increases the operational risk and reduces the flexibility of pruning.
[0006] Fourth, the stability and durability are poor. The connection parts of the device lack effective dust protection structures, and the debris and dust generated during the pruning process can easily enter the internal gaps, accelerating the wear of the components. At the same time, some connection structures lack anti-loosening or buffer designs, and the connections are prone to loosening due to vibration during use, which further affects the pruning stability and shortens the overall service life of the device.
[0007] In summary, existing fruit tree pruning devices have shortcomings in terms of ease of assembly and disassembly, driving precision, scene adaptability, and durability, and cannot meet the needs of efficient, precise, and safe pruning in modern fruit tree planting. There is an urgent need for a pruning device with optimized structural design to solve the above problems. Summary of the Invention
[0008] The purpose of this invention is to provide a branch and leaf pruning device for fruit tree planting, which solves the problems mentioned in the background art.
[0009] To achieve the above objectives, the present invention provides the following technical solution: a branch and leaf pruning device for fruit tree planting, comprising:
[0010] Mounting column;
[0011] The mounting block is snapped into a rectangular opening on the end face of the mounting column. A circular block is fixedly mounted on the end of the mounting block. An upper blade is movably connected to the inner wall of the circular block by a pin. A lower blade is fixedly mounted to the circular block below the upper blade.
[0012] Disassembly and assembly components are used to connect the mounting column and the mounting block;
[0013] Drive components are used to connect the circular block and the mounting post;
[0014] Adjust the components and connect them to the mounting posts.
[0015] Preferably, the disassembly / assembly assembly includes:
[0016] A fixed tube is slidably sleeved on the outside of the right end of the mounting column, and the inner wall of the right end of the fixed tube is fixedly installed with the surface of the mounting block;
[0017] The outer wall of the fixed tube has a second annular groove and a notch, and the notch communicates with the second annular groove.
[0018] The rotating pipe is slidably installed relative to the fixed pipe.
[0019] The inner wall of the rotating tube is fixedly installed with an arc-shaped block that rotates with the second annular groove. The fixed tube is sleeved outside the mounting column, and the arc-shaped block on the inner wall of the rotating tube rotates and engages with the second annular groove of the fixed tube, which can quickly realize the connection / disassembly of the mounting column and the mounting block.
[0020] Preferably, a rubber ring is fixedly installed on the inner wall of the second annular groove. The side of the rubber ring is in contact with the arc-shaped block. The contact between the rubber ring and the arc-shaped block increases the frictional force between the arc-shaped block and the second annular groove by utilizing elasticity, thereby reducing loosening after connection.
[0021] Preferably, the size of the arc-shaped block is smaller than the size of the notch. When the arc-shaped block is smaller than the notch, the arc-shaped block can quickly enter and exit the annular groove through the notch during disassembly and assembly without the need for precise alignment, thus improving the efficiency of disassembly and assembly operations.
[0022] Preferably, an annular plate is fixedly installed at the end of the rotating tube. The annular plate is slidably disposed with a first annular groove opened on the outer wall of the mounting column. A spring is sleeved in the first annular groove and is in contact with the end face of the annular plate. A protective corrugated sleeve is fixedly installed on the end face of the annular plate and is in contact with the outer wall of the mounting column. In conjunction with the elastic force of the spring on the annular plate, the position of the rotating tube can be kept stable and the connection can be prevented from becoming loose. The protective corrugated sleeve can prevent dust and impurities from entering the interior, protect the components, and extend the service life.
[0023] Preferably, the driving component includes:
[0024] A short shaft, one end of which is fixedly installed to the end of a pin;
[0025] The gear is fixedly sleeved on the outer wall of the short shaft;
[0026] A rack is configured to mesh with a gear. A cylinder is fixedly mounted on the end of the rack, and a fixing plate is fixedly mounted on the end of the cylinder. The end of the fixing plate is fixedly mounted to the outer wall of the mounting column. The cylinder drives the rack to move, and the rack meshes with the gear to rotate the short shaft, which in turn drives the upper blade to rotate around the pin. This, in conjunction with the lower blade, completes automatic trimming, replacing manual force and saving manpower.
[0027] Preferably, a limiting rod is fixedly installed on the surface of the rack, and the end of the limiting rod is slidably disposed with a limiting groove opened on the outer wall of the mounting column. The limiting rod slides in the limiting groove to restrict the movement direction of the rack, avoid rack deviation and trimming misalignment, and ensure stable and accurate trimming action.
[0028] Preferably, the adjustment component includes a T-shaped column that is slidably configured with an inner groove inside the mounting column. An anti-slip sleeve is fixedly installed on the outer wall of the left end of the T-shaped column. The T-shaped column can slide along the inner groove of the mounting column to adjust the overall length of the device and adapt to the pruning needs of fruit tree branches and leaves at different heights and distances. The anti-slip sleeve increases the friction between the hand and the T-shaped column, preventing slippage when holding and improving operational safety, making it especially suitable for long-term pruning operations.
[0029] This invention provides a pruning device for fruit tree cultivation. This pruning device for fruit tree cultivation has the following beneficial effects:
[0030] 1. The branch and leaf pruning device for fruit tree planting can quickly connect or disassemble the mounting column and the mounting block through the cooperation of the fixed tube, rotating tube and arc block; the spring force on the ring plate can maintain the stability of the rotating tube position and avoid loosening of the connection; the rubber ring can also increase the contact friction between the arc block and the ring groove; at the same time, the protective corrugated sleeve can prevent dust and impurities from entering the interior, protect the components and extend the overall service life.
[0031] 2. The branch and leaf pruning device for this fruit tree planting uses a cylinder to drive the rack to move. The rack meshes with the gear to rotate the short shaft, which in turn drives the upper blade to rotate around the pin. It works with the lower blade to complete automatic pruning without manual force, greatly saving manpower. In addition, the limiting rod on the rack slides along the limiting groove, which can limit the direction of rack movement, prevent deviation during pruning, and ensure stable and accurate pruning action.
[0032] 3. The branch and leaf pruning device for fruit trees has an adjustable component with a T-shaped column that can slide along the inner groove of the mounting column, allowing for flexible adjustment of the overall length of the device to suit the pruning needs of fruit tree branches and leaves at different heights and distances. The anti-slip sleeve on the T-shaped column increases the friction between the hand and the components, preventing slippage during gripping and improving safety during operation, making it especially suitable for long-term pruning operations.

[0044] like Figure 1-6 As shown, the present invention provides a technical solution: a branch and leaf pruning device for fruit tree planting, comprising:
[0045] Mounting column 1;
[0046] Mounting block 21 is snapped into a rectangular opening on the end face of mounting column 1. A circular block 9 is fixedly mounted on the end of mounting block 21. An upper blade 10 is movably connected to the inner wall of the circular block 9 via a pin 9. A lower blade 11 is fixedly mounted to the circular block 9 below the upper blade 10.
[0047] A disassembly / assembly assembly is used to connect the mounting column 1 and the mounting block 21;
[0048] The disassembly and assembly components include:
[0049] The fixing tube 7 is slidably sleeved on the outside of the right end of the mounting column 1, and the inner wall of the right end of the fixing tube 1 is fixedly installed with the surface of the mounting block 27.
[0050] The outer wall of the fixed tube 7 is provided with a second annular groove 23 and a notch 24, and the notch 24 is connected to the second annular groove 23.
[0051] The rotating pipe 6 is slidably installed with the fixed pipe 7;
[0052] The inner wall of the rotating tube 6 is fixedly equipped with an arc-shaped block 26 that rotatably interacts with the second annular groove 23. A rubber ring 25 is fixedly installed on the inner wall of the second annular groove 23. The side of the rubber ring 25 contacts the arc-shaped block 26. The contact between the rubber ring 25 and the arc-shaped block 26 utilizes elasticity to increase the contact friction between the arc-shaped block 26 and the second annular groove 23, reducing loosening after connection. The size of the arc-shaped block 26 is smaller than the size of the notch 24. During disassembly and assembly, the arc-shaped block 26 can quickly enter and exit the annular groove through the notch 24 without precise alignment, improving the efficiency of disassembly and assembly operations. An annular plate 5 is fixedly installed at the end of the rotating tube 6. The annular plate 5 and the outer wall of the mounting column 1 are slidably connected to the first annular groove 21. A spring 22 is fitted inside the first annular groove 21 and is in contact with the end face of the annular plate 5. A protective corrugated sleeve 4 is fixedly installed on the outer wall of the mounting column 1 and is fitted on the end face of the annular plate 5. The fixing tube 7 is fitted outside the mounting column 1, and the arc-shaped block 26 on the inner wall of the rotating tube 6 is rotatably engaged with the second annular groove 23 of the fixing tube 7, which can quickly realize the connection / disconnection of the mounting column 1 and the mounting block 27. With the elastic force of the spring 22 on the annular plate 5, the position of the rotating tube can be kept stable and the connection can be prevented from loosening. The protective corrugated sleeve 4 can block dust and impurities from entering the interior, protect the components and extend the service life.
[0053] Drive assembly for connecting circular block 8 and mounting post 1;
[0054] The driver components include:
[0055] Short shaft 16, one end of which is fixedly installed to the end of pin 9;
[0056] Gear 15 is fixedly sleeved on the outer wall of short shaft 16;
[0057] A rack 12 meshes with a gear 15. A cylinder 13 is fixedly mounted on the end of the rack 12, and a fixing plate 4 is fixedly mounted on the end of the cylinder 13. The end of the fixing plate 4 is fixedly mounted to the outer wall of the mounting column 1. A limit rod 18 is fixedly mounted on the surface of the rack 12. The end of the limit rod 18 slides in a limit groove 17 opened on the outer wall of the mounting column 1. The cylinder 13 drives the rack 13 to move. The rack 12 meshes with the gear 15 to rotate the short shaft 16, which in turn drives the upper blade 10 to rotate around the pin. It works with the lower blade 1 to complete automatic trimming, replacing manual force and saving manpower. The limit rod 18 slides in the limit groove 17 to limit the direction of movement of the rack 13, preventing the rack 13 from deviating and causing trimming misalignment, and ensuring stable and accurate trimming action.
[0058] Adjust the component and connect it to mounting post 1;
[0059] The adjustment component includes a T-shaped column 20, which is slidably set with an inner sliding groove 19 inside the mounting column 1. An anti-slip sleeve 3 is fixedly installed on the outer wall of the left end of the T-shaped column 20. The T-shaped column 20 can slide along the inner sliding groove 19 of the mounting column 1 to adjust the overall length of the device and adapt to the pruning needs of fruit tree branches and leaves at different heights and distances. The anti-slip sleeve 3 increases the friction between the hand and the T-shaped column 20, preventing slippage when holding and improving operational safety, especially suitable for long-term pruning operations.
[0060] When using this fruit tree pruning device, the components are first adjusted to adapt to different pruning scenarios: pushing the T-shaped column 20 along the inner groove 19 inside the mounting column 1 adjusts the overall length of the device to accommodate fruit tree branches of different heights or distances. Simultaneously, the anti-slip sleeve 3 on the outer wall of the left end of the T-shaped column 20 increases hand grip friction, preventing slippage during operation. The pruning power is provided by the drive assembly; the cylinder 13 extends and retracts, causing the rack 12 fixed at the end to move. The gear 15 meshing with the rack 12 rotates accordingly. Because the gear 15 is fixedly sleeved on the outer wall of the short shaft 16, the short shaft 16 drives the pin 9 fixed at the end to rotate, thereby causing the upper blade 10, movably connected to the pin 9, to rotate around the inner wall of the circular block 8, cooperating with the lower blade 11 fixed to the circular block 8 to complete the branch and leaf trimming. Furthermore, the limiting rod 18 fixed on the surface of the rack 12 will slide along the limiting groove 17 on the outer wall of the mounting post 1 to prevent the rack 12 from shifting and causing misalignment during trimming. In addition, the assembly and disassembly components ensure stable connection: the fixing tube 7 is sleeved on the outside of the right end of the mounting post 1 and fixed to the mounting block 27. The arc-shaped block 26 on the inner wall of the rotating tube 6 rotates in the second annular groove 23 of the fixing tube 7 to maintain the connection between the mounting post 1 and the mounting block 27. The spring 22 in the first annular groove 21 of the mounting post 1 applies elastic force to the annular plate 5 at the end of the rotating tube 6, which can keep the position of the rotating tube 6 stable. The rubber ring 25 in the second annular groove 23 contacts the arc-shaped block 26 to increase friction and reduce loosening. The protective corrugated sleeve 4 on the outer wall of the mounting post 1 can prevent dust and impurities from entering the component, protect the components and extend their service life.
[0061] The above description is merely an illustrative embodiment of the present invention and is not intended to limit the scope of the invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention. Furthermore, it should be noted that the components of the present invention are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, the present invention naturally covers other combinations and specific applications related to the inventive points of this case.
