Description

Technical Field

[0001] This invention relates to the field of fruit tree branch pruning technology, specifically to an adjustable pruning device for fruit trees. Background Technology

[0002] In modern fruit tree industry, scientific and effective pruning is a key step in ensuring fruit yield and quality. Proper pruning optimizes the tree canopy structure, promotes ventilation and light penetration, regulates the balance between growth and fruiting, and thus improves fruit quality and yield.

[0003] Traditional pruning shears are limited by their structural design, with a fixed opening size that can only fit fruit tree branches within a specific diameter range. In actual pruning operations, fruit tree branches vary significantly in thickness. When encountering thicker branches that exceed the opening range of the pruning shears, it is impossible to adjust them flexibly according to the actual thickness of the branch. When encountering thicker branches, it is necessary to switch to larger pruning tools midway through the pruning process. This process not only requires interrupting the pruning work, consuming extra time and energy, but may also disrupt the work rhythm due to frequent tool changes, significantly reducing the overall pruning efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable pruning device for fruit trees to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable pruning device for fruit trees, comprising a handle, a fixed block fixedly connected to the end of the handle, two pruning shears for pruning fruit trees mounted on the fixed block, the pruning shears including a first pruning shear and a second pruning shear; an adjustment component for changing the spacing between the pruning shears mounted on the fixed block, and a limiting component for limiting the pruning shears; and a hydraulic cylinder for pruning the branches of the fruit trees mounted between the pruning shears.

[0006] As a further aspect of the present invention, the adjusting component includes a fixing piece fixedly connected to the fixing block, and the pruning shears are slidably connected to the fixing block via a sliding groove; The sliding groove includes a straight groove and an adjusting groove. Sliding posts are fixedly connected to both trimmer blades. The first trimmer blade is slidably connected to the straight groove via the sliding posts. The second trimmer blade is adjusted to the adjusting groove via the sliding posts. The adjustment groove includes an inclined groove and a trimming groove that can increase the distance between the first trimmer and the second trimmer.

[0007] As a further embodiment of the present invention, the adjustment assembly further includes a drive rod capable of driving the first trimmer and the second trimmer, wherein one of the sliding columns is fixedly connected to the first trimmer, and the other sliding column is slidably connected to the second trimmer in the horizontal direction, and the drive rod is provided with a groove for the sliding column to slide.

[0008] As a further embodiment of the present invention, the limiting component includes a sliding plate that is slidably connected to the second trimmer and is capable of extension and retraction. The sliding plate is slidably connected to the second trimmer in the same direction. A first limiting piece is slidably connected to the lower surface of the sliding plate, and the first limiting piece is slidably connected to a fixed piece.

[0009] As a further embodiment of the present invention, the limiting component further includes a second limiting piece capable of limiting the second trimmer after the adjustment of the spacing. The second limiting piece is slidably connected to the second trimmer in the horizontal direction, and the end of the second limiting piece opposite to the sliding plate is fixedly connected. A wedge-shaped post is engaged on the second limiting piece, and the wedge-shaped post is elastically slidably connected to the second trimmer in the vertical direction by a return spring.

[0010] As a further embodiment of the present invention, the fixing block is provided with clamping plates capable of clamping fruit trees, and a driving cylinder capable of driving the clamping plates to clamp the fruit trees is provided between the two clamping plates.

[0011] As a further embodiment of the present invention, a push plate for pushing the drive rod is fixedly connected to the upper surface of the drive rod, and a drive groove is provided on the fixed plate to maintain the linear movement of the drive rod.

[0012] As a further embodiment of the present invention, the thickness of the second limiting piece is equal to the thickness of the sliding plate; a removable battery is provided at the end of the handle away from the fixed block, and the battery can provide power to the hydraulic cylinder.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. By pushing the drive rod forward, the sliding column of the second pruning shears moves along the inclined groove, while the first pruning shears move synchronously along the straight groove. Utilizing the inclined characteristics of the groove, the distance between the two pruning shears is increased. After adapting to the branch diameter, the hydraulic cylinder drives the pruning shears to close, completing the pruning. The distance between the first and second pruning shears can be flexibly adjusted to suit fruit tree branches of different thicknesses without the need to change tools. The simple structural design allows for multi-scenario adaptation without complex parts, significantly improving the device's versatility and practicality. It also reduces the frequency of tool replacements, lowers operating costs, and is simple and efficient to operate, significantly optimizing the pruning experience.

[0014] 2. When adjusting the spacing of the second trimmer shears, the wedge-shaped column can automatically disengage from its original slot as it moves. After adjustment, it can precisely engage with the corresponding slot under the action of the return spring to complete the fixation. Together with the sliding plate with its position unchanged, it forms a stable limit, which not only ensures the smooth adjustment of the spacing between the first and second trimmer shears, but also firmly fixes the position of the second trimmer shears during trimming, ensuring that the trimming spacing is accurately matched with the diameter of the fruit tree, improving the cutting accuracy and stability, and making the operation more convenient and efficient.

[0017] Please see Figures 1-6 The present invention provides a technical solution: an adjustable pruning device for fruit trees, including a handle 1, a fixing block 2 fixedly connected to the end of the handle 1, two pruning shears 3 capable of pruning fruit trees on the fixing block 2, the pruning shears 3 including a first pruning shear 31 and a second pruning shear 32; an adjustment component capable of changing the spacing between the pruning shears 3 is provided on the fixing block 2, a limiting component capable of limiting the pruning shears 3 is provided on the fixing block 2; and a hydraulic cylinder 33 capable of pruning the branches of the fruit trees is provided between the pruning shears 3.

[0018] When the fruit tree is working with the adjustable pruning device, it is held by the handle 1, and the battery 21 powers the hydraulic cylinder 33. The two pruning shears 3 (first pruning shears 31 and second pruning shears 32) on the fixed block 2 are adjusted in distance by the adjustment component to adapt to branches of different thicknesses. After adjustment, the limiting component fixes the pruning shears 3, and then the hydraulic cylinder 33 drives the pruning shears 3 to close and complete the pruning. It can flexibly adapt to different branch thicknesses, is easy to operate and has reliable power, reduces labor intensity, and the auxiliary clamping function further improves the safety and efficiency of the operation.

[0019] As a further embodiment of the present invention, the adjustment component includes a fixing piece 4 fixedly connected to the fixing block 2, and the pruning shears 3 are slidably connected to the fixing block 2 through a sliding groove; The sliding groove includes a straight groove 5 and an adjusting groove 6. Sliding posts 7 are fixedly connected to both trimming blades 3. The first trimming blade 31 is slidably connected to the straight groove 5 through the sliding posts 7. The second trimming blade 32 is adjusted to the groove 6 through the sliding posts 7. The adjustment groove 6 includes an inclined groove 9 and a trimming groove 8 that can increase the distance between the first trimmer 31 and the second trimmer 32.

[0020] As a further embodiment of the present invention, the adjustment assembly further includes a drive rod 10 capable of driving the first trimmer 31 and the second trimmer 32, wherein one of the sliding posts 7 is fixedly connected to the first trimmer 31, and the other sliding post 7 is slidably connected to the second trimmer 32 in the horizontal direction, and the drive rod 10 is provided with a groove 11 for sliding of the sliding post 7.

[0021] When working: When it is necessary to prune the branches of relatively thick fruit trees, such as Figure 6 As shown, pushing the drive rod 10 forward causes the sliding column on the second pruning shears 32 to move along the inclined groove 9, while the first pruning shears 31 moves forward along the straight groove 5, maintaining the same position as the second pruning shears 32. Since the inclined groove 9 is inclined, the distance between the first pruning shears 31 and the second pruning shears 32 increases, allowing for adaptation to branches of different thicknesses. When 32 moves to the position of the middle pruning groove 8, making the distance between 31 and 32 match the diameter of the fruit tree, the hydraulic cylinder 33 is activated, driving the second pruning shears 32 to move closer to the first pruning shears 31, thus pruning the branches of the fruit tree. This achieves the adjustment of the distance between the first pruning shears 31 and the second pruning shears 32, adapting to various branch diameters without a complex structure, improving the versatility and practicality of the device, reducing operating costs, and simplifying operation.

[0022] When pruning thicker fruit tree branches, this pruning device moves the sliding column of the second pruning shears 32 along the inclined groove 9 by pushing the drive rod 10 forward, while the first pruning shears 31 moves synchronously along the straight groove 5. The inclined groove 9 increases the distance between the two shears, adapting to the branch diameter. Then, the hydraulic cylinder 33 drives the shears to close, completing the cut. The distance between the first and second pruning shears 31 can be flexibly adjusted to suit different thicknesses of fruit tree branches (especially thicker ones), eliminating the need to change tools. The simple structural design allows for multi-scenario adaptation without complex components, significantly improving the device's versatility and practicality. It also reduces tool replacement frequency, lowers operating costs, and is simple and efficient to operate, significantly optimizing the pruning experience.

[0023] As a further embodiment of the present invention, the limiting component includes a sliding plate 12 that is slidably connected to the second trimmer 32 and is capable of extension and retraction. The sliding plate 12 is slidably connected to the second trimmer 32 in a horizontal direction. A limiting piece 13 is slidably connected to the lower surface of the sliding plate 12, and the limiting piece 13 is slidably connected to the fixing piece 4.

[0024] As a further embodiment of the present invention, the limiting component includes a sliding plate 12 that is slidably connected to the second trimmer 32 and is capable of extension and retraction. The sliding plate 12 is slidably connected to the second trimmer 32 in a horizontal direction. A first limiting piece 13 is slidably connected to the lower surface of the sliding plate 12, and the first limiting piece 13 is slidably connected to the fixed piece 4.

[0025] As a further embodiment of the present invention, the limiting component further includes a second limiting piece 14 capable of limiting the second trimmer 32 after the spacing of the second trimmer 32 is adjusted. The second limiting piece 14 is slidably connected to the second trimmer 32 in the horizontal direction, and the end of the second limiting piece 14 opposite to the sliding plate 12 is fixedly connected. A wedge-shaped post 15 is engaged on the second limiting piece 14, and the wedge-shaped post 15 is elastically slidably connected to the second trimmer 32 in the vertical direction through a return spring 16.

[0026] At work: such as Figures 3-6As shown, when the second trimmer 32 adjusts the spacing, as it moves diagonally to the right along 9, increasing the distance between it and the first trimmer 31, the sliding plate 12 cannot slide to the right. During this rightward movement, the second trimmer 32 creates a relative displacement with the sliding plate 12. This causes the inclined surface of the wedge-shaped post 15, which follows the second trimmer 32 to move to the right, to be pushed upwards by the groove of the second limiting plate 14, causing the wedge-shaped post 15 to leave the first groove of the second limiting plate 14. When the second trimming shears 32 move to the position of the middle trimming groove 8, so that the distance between the first trimming shears 31 and the second trimming shears 32 matches the diameter of the fruit tree, the wedge-shaped column 15 reaches the slot in the middle of the second limiting plate 14. Under the action of the return spring 16, the unloading column 15 engages with the second limiting plate 14, thereby limiting and fixing the second trimming shears 32. Finally, the hydraulic cylinder 33 is activated to drive the second trimming shears 32 to move closer to the first trimming shears 31 through the first limiting plate 13, thus cutting the fruit tree. When the spacing of the second trimming shears 32 is adjusted, the wedge-shaped column 15 can automatically disengage from the original slot as it moves. After adjustment, it can accurately engage with the corresponding slot under the action of the return spring to complete the fixation. Together with the sliding plate 12 with the position unchanged, it forms a stable limit, which not only ensures the smoothness of the spacing adjustment between the first trimming shears 31 and the second trimming shears 32, but also firmly fixes the position of the second trimming shears 32 during trimming, ensuring that the trimming spacing is accurately matched with the diameter of the fruit tree, improving the cutting accuracy and stability, and making the operation more convenient and efficient.

[0027] As a further embodiment of the present invention, the fixing block 2 is provided with a clamping piece 20 capable of clamping the fruit wood, and a driving cylinder 21 capable of driving the clamping piece 20 to clamp the fruit wood is provided between the two clamping pieces 20.

[0028] During operation: Driven by the cylinder 21, the two clamping plates 20 move relative to each other to clamp the branches of the fruit tree, thereby achieving auxiliary clamping of the branches.

[0029] As a further embodiment of the present invention, a push plate 17 for pushing the drive rod 10 is fixedly connected to the upper surface of the drive rod 10, and a drive groove 18 for maintaining the linear movement of the drive rod 10 is provided on the fixing plate 4.

[0030] As a further embodiment of the present invention, the thickness of the second limiting piece 14 is equal to the thickness of the sliding plate 12; a removable battery 21 is provided at the end of the handle 1 away from the fixing block 2, and the battery 21 can provide power to the hydraulic cylinder 14.
