Description

Technical Field

[0001] This invention belongs to the field of seedling cultivation technology, specifically relating to a tree seedling pruning device for forestry engineering. Background Technology

[0002] Forestry engineering, based on the principles of efficient utilization and sustainable development of forest resources, applies engineering technology to activities related to forest resource cultivation, development, and processing of forest products. In forestry engineering, seedling cultivation is the fundamental step in forest cultivation, and pruning operations are integral to the entire seedling cultivation process, directly impacting seedling morphology control, growth quality, and subsequent afforestation effectiveness. Currently, tree seedling pruning primarily relies on manual labor, with commonly used tools including handheld pruning shears and high-branch shears.

[0003] Existing technology uses high-branch shears to prune high branches. This pruning method only cuts off the branches, and the cut-off waste branches are left at the top of the seedling. These waste branches need to be cleaned up again, resulting in low efficiency of tree seedling pruning. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a tree seedling pruning device for forestry engineering, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides a tree seedling pruning device for forestry engineering, including a movable base, an electric push rod mounted on the upper surface of the movable base, an inclined platform mounted on the movable end of the electric push rod, and an electric shears mounted on the upper surface of the inclined platform. The inclined platform is equipped with a waste branch clamping assembly on its side. The waste branch clamping assembly includes a bracket one, a bracket two hinged to the top of the bracket one, a through groove in the middle of the bracket two, a pressing rod one fixed to the left side of the bracket one, an arc-shaped electric telescopic rod fixed to the middle of the right side of the bracket one, a limit bracket fixed to the outside of the right side of the bracket one, a pressing rod two fixed to the side of the limit bracket, two gears symmetrically fixed to the back side of the bracket two, each gear having a clamping rod fixed to it, a double-toothed slide rod slidably connected to the middle of the back side of the bracket two within the through groove, the two sides of the double-toothed slide rod meshing with the two gears respectively, and a shaped groove opened at the lower end of the inner part of the double-toothed slide rod. This application incorporates a waste branch clamping component. After the electric shears complete the pruning action, the arc-shaped electric telescopic rod pushes the second support to rotate, causing the first and second squeezing rods to sequentially squeeze the double-toothed sliding rod. This drives two gears to rotate the two clamping rods relative to each other, clamping the cut waste branches and removing them from the top of the sapling as the second support rotates. This prevents waste branches from remaining on the sapling, eliminating the need for subsequent secondary cleaning and effectively improving the efficiency of pruning operations.

[0006] Preferably, the top and bottom of the irregular groove are inclined surfaces, and damping rollers are installed on both sides of the double-toothed slide bar, with the damping rollers fitting against the inner wall of the through groove.

[0007] Preferably, the top ends of both the first extrusion rod and the second extrusion rod are semi-circular structures, and the first extrusion rod and the second extrusion rod are located on both sides of the movement trajectory of the double-toothed slide bar.

[0008] Preferably, the movable end of the arc-shaped electric telescopic rod is connected to the second bracket, and the maximum angle of motion of the movable end of the arc-shaped electric telescopic rod to rotate the second bracket is ninety degrees.

[0009] Preferably, the upper surface of the inclined platform is equipped with a protective liquid application component for applying protective liquid to the pruned areas of tree seedlings.

[0010] Preferably, the protective liquid application assembly includes an L-shaped bracket fixed to the upper surface of an inclined platform, an arc-shaped friction rod fixed to the side of the movable handle of an electric scissor, and a friction wheel rotatably connected to the upper surface of the inclined platform. A storage box is fixed to the side of the L-shaped bracket, and an opening is provided at the bottom plate of the storage box, through which a protective liquid roller is rotatably connected. A connecting block is fixed to the top of the friction wheel, and a connecting rod is fixed to the side of the connecting block. A second friction wheel is rotatably connected to the side of the connecting rod, and an application roller is fixed to the side of the second friction wheel. An arc-shaped friction rod is fixed to the side of the L-shaped bracket. The first friction wheel and the arc-shaped friction rod are pressed together, and the second friction wheel and the arc-shaped friction rod are pressed together. This application incorporates a protective liquid application component. When the handle of the electric shears rotates, it drives the first arc-shaped friction rod to rotate the first friction wheel. This, in turn, drives the second friction wheel to roll along the second arc-shaped friction rod via a connecting rod. As the application roller rotates, it evenly applies the protective liquid from the storage tank's protective liquid roller to the pruning cut of the seedling, achieving immediate sealing and protection of the pruning wound. This effectively prevents the invasion of pathogens and moisture evaporation, promoting rapid healing of the seedling.

[0011] Preferably, the protective liquid roller is wrapped with nylon material, and the protective liquid roller is initially attached to the application roller.

[0012] Preferably, a dispersing assembly is fitted at the edge of the upper surface of the inclined platform. The dispersing assembly includes multiple protruding rods fixed to the outer side of an arc-shaped friction rod and a dispersing rod. The dispersing rod is rotatably connected to the edge of the upper surface of the inclined platform via a rotating shaft. A torsion spring is fitted inside the rotating shaft at the rotatable connection between the dispersing rod and the inclined platform, and a horizontal plate is fixed to the outer side of the rotating shaft. By setting up the dispersing assembly, during the rotation of the electric shears' handle, the multiple protruding rods on the outer side of the arc-shaped friction rod sequentially push the horizontal plate, causing the dispersing rod to overcome the torsion spring force and rotate outward around the rotating shaft. This disperses the branches and leaves around the pruning position to both sides, creating sufficient working space for the electric shears, preventing surrounding branches and leaves from interfering with the cutting path, ensuring the accuracy of the pruning position and the flatness of the cut, and improving the pruning quality.

[0013] Preferably, the cross plate is located on the movement trajectory of the multiple protruding rods.

[0014] The advantages of this application are: (1) By setting up a waste branch clamping component, after the electric shears complete the pruning action, the arc-shaped electric telescopic rod pushes the second support to rotate, so that the first and second squeezing rods squeeze the double toothed slide bar in sequence, driving the two gears to drive the two clamping rods to rotate relative to each other, clamping the cut waste branches and pulling them away from the top of the seedling as the second support rotates, avoiding waste branches remaining on the seedling, saving the subsequent secondary cleaning process, and effectively improving the efficiency of pruning operations.

[0015] (2) This application sets up a protective liquid coating component. When the electric shears handle rotates, it drives the arc-shaped friction rod to rotate the friction wheel. Then, through the connecting rod, the friction wheel rolls along the arc-shaped friction rod. During the rotation, the coating roller evenly coats the protective liquid on the protective liquid roller in the storage box onto the pruning cut of the seedling, thereby achieving immediate sealing and protection of the pruning wound, effectively preventing the invasion of pathogens and the evaporation of moisture, and promoting the rapid healing of the seedling.

[0016] (3) By setting up a prying component, during the rotation of the electric shears' handle, multiple protrusions on the outer side of the arc-shaped friction rod push the horizontal plate in sequence, causing the prying rod to overcome the torsion spring force and rotate outward around the axis, thus prying aside the branches and leaves around the pruning position to both sides, freeing up sufficient working space for the electric shears, avoiding interference from the surrounding branches and leaves on the cutting path, ensuring the accuracy of the pruning position and the flatness of the cut, and improving the pruning quality.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0020] Example 1, as Figures 1-6As shown, a tree seedling pruning device for forestry engineering includes a movable base 100, an electric push rod 200 is mounted on the upper surface of the movable base 100, an inclined platform 300 is mounted on the movable end of the electric push rod 200, and an electric shears 400 is mounted on the upper surface of the inclined platform 300. The inclined platform 300 is equipped with a waste branch clamping assembly 500 on its side. The waste branch clamping assembly 500 includes a first bracket 501, a second bracket 502 hinged to the top of the first bracket 501, a through groove 503 in the middle of the second bracket 502, a first pressing rod 504 fixed to the left side of the first bracket 501, an arc-shaped electric telescopic rod 507 fixed to the middle of the right side of the first bracket 501, a limit bracket 505 fixed to the outside of the right side of the first bracket 501, a second pressing rod 506 fixed to the side of the limit bracket 505, two gears 509 symmetrically fixed to the back side of the second bracket 502, each gear 509 having a clamping rod 508 fixed to it, and a double-toothed slide rod 510 slidably connected to the middle of the back side of the second bracket 502 within the through groove 503, with the double-toothed slide rod 510 having two sides respectively Engaging with two gears 509, the lower end of the double-toothed slide bar 510 has a shaped groove 511. The top and bottom of the shaped groove 511 are inclined surfaces. Both sides of the double-toothed slide bar 510 are equipped with damping rollers 512, and the damping rollers 512 are in contact with the inner wall of the through groove 503. The damping rollers 512 and the inner wall of the through groove 503 are in contact to ensure that the double-toothed slide bar 510 slides smoothly and has a damping feel. The tops of the first extrusion rod 504 and the second extrusion rod 506 are both semi-arc structures. The first extrusion rod 504 and the second extrusion rod 506 are located on both sides of the movement trajectory of the double-toothed slide bar 510. The movable end of the arc-shaped electric telescopic rod 507 is connected to the second bracket 502. The maximum movement angle of the arc-shaped electric telescopic rod 507 that pushes the second bracket 502 to rotate is ninety degrees. This application incorporates a waste branch clamping component 500. After the electric shears 400 completes the pruning action, the arc-shaped electric telescopic rod 507 pushes the second support 502 to rotate, causing the first squeezing rod 504 and the second squeezing rod 506 to sequentially squeeze the double-toothed slide bar 510. This drives two gears 509 to rotate the two clamping rods 508 relative to each other, clamping the cut waste branches and removing them from the top of the sapling as the second support 502 rotates. This prevents waste branches from remaining on the sapling, eliminating the need for subsequent secondary cleaning and effectively improving the efficiency of pruning operations.

[0021] In practical use, when the electric shears 400 are moved to the trimming area, the arc-shaped electric telescopic rod 507 is activated. Its movable end pushes the bracket 2 502 to rotate around the hinge point at the top of the bracket 1 501. During the rotation of the bracket 2 502, the double-toothed slide rod 510, which is slidably connected in the through groove 503 inside the bracket 2 502, moves along with it. When the double-toothed slide rod 510 moves to the pressing rod 1 504, the semi-arc structure at the top of the pressing rod 1 504 extends into the irregular groove 511, pressing the inclined surface at the top of the irregular groove 511 and pushing the double-toothed slide rod 510 to slide downward along the through groove 503. The teeth on both sides of the double-toothed slide rod 510 drive the two teeth that mesh with it to slide downward. The gears 509 rotate synchronously, and the two gears 509 drive the two clamping rods 508 to rotate relative to each other, thereby clamping the upper part of the branch to be pruned. Then, the electric shears 400 are started to prune. After pruning, the arc-shaped electric telescopic rod 507 controls the bracket 2 502 to rotate in the opposite direction, so that the bracket 2 502 rotates to the limit bracket 505. At this time, the top of the squeezing rod 2 506 extends into the irregular groove 511, squeezing the inclined surface at the bottom of the irregular groove 511, pushing the double toothed slide rod 510 to slide upward and reset. The two gears 509 rotate in the opposite direction, causing the two clamping rods 508 to open, releasing the waste branch and letting it fall off, thus solving the problem of waste branches remaining on the top of the tree seedling. At the same time, the damping roller 512 fits against the inner wall of the through groove 503, ensuring that the double toothed slide bar 510 slides smoothly and has a damping feel.

[0022] Example 2, as Figure 7 and Figure 8As shown, based on Embodiment 1, the upper surface of the inclined platform 300 is equipped with a protective liquid application component 600 for applying protective liquid to the pruned areas of tree seedlings. The protective liquid application component 600 includes an L-shaped bracket 601 fixed to the upper surface of the inclined platform 300, an arc-shaped friction rod 602 fixed to the side of the movable handle of the electric shears 400, and a friction wheel 604 rotatably connected to the upper surface of the inclined platform 300. A storage box 603 is fixed to the side of the L-shaped bracket 601. An opening is provided at the bottom plate of the storage box 603, and a protective liquid roller 610 is rotatably connected inside the opening. A connecting block 605 is fixed to the top of friction wheel 604, a connecting rod 606 is fixed to the side of the connecting block 605, a second friction wheel 607 is rotatably connected to the side of the connecting rod 606, an applicator roller 608 is fixed to the side of the second friction wheel 607, an arc-shaped friction rod 609 is fixed to the side of the L-shaped bracket 601, the first friction wheel 604 and the first arc-shaped friction rod 602 are pressed and adhered together, the second friction wheel 607 and the second arc-shaped friction rod 609 are pressed and adhered together, the outer surface of the protective liquid roller 610 is wrapped with nylon material, and the protective liquid roller 610 is initially adhered to the applicator roller 608. This application utilizes a protective liquid application component 600. When the handle of the electric shears 400 rotates, it drives the first arc-shaped friction rod 602 to rotate the first friction wheel 604. This, in turn, drives the second friction wheel 607 to roll along the second arc-shaped friction rod 609 via the connecting rod 606. As the application roller 608 rotates, it evenly applies the protective liquid from the protective liquid roller 610 in the storage box 603 to the pruning cut of the seedling, achieving immediate sealing and protection of the pruning wound. This effectively prevents the invasion of pathogens and the evaporation of moisture, promoting rapid healing of the seedling.

[0023] In specific use, based on Embodiment 1, when the electric scissors 400 perform a trimming action, its movable handle rotates, and the arc-shaped friction rod 602 fixed to the side of the movable handle rotates accordingly. Because the arc-shaped friction rod 602 is pressed and adhered to the friction wheel 604, the frictional force drives the friction wheel 604 to rotate around its rotation center. When the friction wheel 604 rotates, the connecting rod 606 swings synchronously through the connecting block 605 at the top. The friction wheel 607 on the side of the connecting rod 606, during its movement with the connecting rod 606, interacts with the friction wheel fixed to the L-shaped support. The arc-shaped friction rod 609 on the side of the frame 601 is pressed and adhered, generating rolling friction and rotating. The friction wheel 607 rotates, driving the coating roller 608 fixed to it to rotate. At the same time, the protective liquid roller 610 in the bottom opening of the storage box 603 is in contact with the coating roller 608 in the initial state. The nylon material wrapped around the protective liquid roller 610 absorbs the protective liquid in the storage box 603 and transfers the protective liquid to the surface of the rotating coating roller 608. The coating roller 608, with the rotation of the friction wheel 607, evenly coats the protective liquid onto the cut of the seedling.

[0024] Example 3, as Figures 7-9As shown, based on Embodiment 2, a disengaging assembly 700 is assembled at the edge of the upper surface of the inclined platform 300. The disengaging assembly 700 includes multiple protruding rods 702 fixed to the outside of the arc-shaped friction rod 602 and a disengaging rod 701. The disengaging rod 701 is rotatably connected to the edge of the upper surface of the inclined platform 300 through a rotating shaft 703. A torsion spring 704 is assembled inside the rotating shaft 703 at the rotatable connection between the disengaging rod 701 and the inclined platform 300. A horizontal plate 705 is fixed to the outside of the rotating shaft 703. The horizontal plate 705 is located on the movement trajectory of the multiple protruding rods 702. This application, by setting up a dispersing component 700, allows multiple protruding rods 702 on the outer side of the arc-shaped friction rod 602 to sequentially push the horizontal plate 705 during the rotation of the movable handle of the electric shears 400. This causes the dispersing rod 701 to overcome the elastic force of the torsion spring 704 and rotate outward around the pivot 703, thus dispersing the branches and leaves around the pruning position to both sides. This provides ample working space for the electric shears 400, avoids interference from surrounding branches and leaves on the cutting path, ensures the accuracy of the pruning position and the flatness of the cut, and improves the pruning quality.

[0025] In specific use, based on Embodiment 2, before pruning, when the electric shears 400 are pushed to the pruning location, the pusher rod 701 will initially push aside the accumulated branches. When the movable handle of the electric shears 400 rotates to prune, multiple protruding rods 702 fixed to the outside of the arc-shaped friction rod 602 move synchronously with the arc-shaped friction rod 602. When the protruding rods 702 rotate with the arc-shaped friction rod 602 to the position of the horizontal plate 705, the protruding rods 702 contact the horizontal plate 705 and push the horizontal plate 705. The horizontal plate 705 drives the rotating shaft 703 to rotate, thereby causing the pusher rod 701 to overcome the elastic force of the torsion spring 704 inside the rotating shaft 703 and flip outward around the rotating shaft 703, pushing aside the branches and leaves around the pruning position to both sides, providing sufficient working space for the electric shears 400 to cut.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
