Description

Technical Field

[0001] This utility model relates to the technical field of green belt pruning equipment, specifically a shrub green belt pruning device. Background Technology

[0002] Shrubs refer to short trees that do not have a distinct main trunk and grow in clumps. They can generally be divided into several categories, such as those for flowering, fruiting, and branches. Short and clump-forming woody plants are generally broad-leaved plants, but some coniferous plants are also shrubs. Green belts refer to strips of landscaping that provide greenery. They can relieve visual fatigue, purify the environment, beautify the city, and reduce traffic accidents, and they occupy an irreplaceable and important position in the city. Garden shrub green belts refer to green belts formed by planting shrubs.

[0003] However, existing shrub pruning devices have many inconveniences in practical use, seriously affecting the efficiency and safety of pruning operations. For example, as the saw blade rotates, it moves forward with the traction equipment (such as a tractor). When cutting shrub branches, the high-speed rotating blades are prone to getting stuck in the gap between the saw blade and the outer casing, or wrapped around the crossbeam structure where the drive motor is installed, due to the elasticity of the branches or fiber entanglement. This may accelerate equipment wear or even cause malfunctions. In addition, because the cutting angle of the saw blade is fixed, it cannot be flexibly adjusted according to the height or density of the shrubs, which can easily lead to uneven pruning and affect the aesthetics of the green belt. To address these issues, a new shrub pruning device for green belts is proposed. Utility Model Content

[0004] Based on this, the present invention aims to at least solve one of the technical problems existing in the prior art. To this end, a shrub pruning device is proposed, which can comprehensively and precisely prune the tops and sides of shrubs to improve the aesthetics of the pruned shrubs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shrubland green belt pruning device, comprising a square strip, the outer wall of which is fitted with a load-bearing beam capable of rising and falling along its length, the end of which is rotatably connected to a hydraulic motor, the upper surface of which is mounted with a second hydraulic rod capable of pulling the hydraulic motor to rotate vertically, three sets of pruning components are provided below the hydraulic motor, and the output end of the hydraulic motor is provided with a mechanism capable of pulling the three sets of pruning components to operate;

[0006] The output end of the hydraulic motor is connected to a central disc. Three sets of positioning tubes are installed on the outer wall of the central disc along its circumference. Each set of positioning tubes has a mounting plate welded to its end. Each set of pruning components includes a motor mounted on the outer wall of the mounting plate. The output end of the motor is equipped with a saw disc for pruning shrubs.

[0007] As a preferred technical solution, the end of the load-bearing beam is provided with a frame that is sleeved on the outer wall of the square bar and can slide up and down. A first hydraulic rod is installed on the top of the load-bearing beam near the side of the square bar. The telescopic end of the first hydraulic rod is fixed to the top of the square bar by a plate.

[0008] As a preferred technical solution, the telescopic end of the second hydraulic rod is rotatably mounted on the upper surface of the load-bearing beam, and the other end of the second hydraulic rod is rotatably connected to a connecting plate, the end of which is rotatably connected to the outer wall of the hydraulic motor.

[0009] As a preferred technical solution, an arc-shaped reinforcing rib is welded between two adjacent sets of positioning tubes, and the three sets of arc-shaped reinforcing ribs form an annular reinforcing rib on the outer wall of the positioning tube. A reinforcing plate is welded at the end of the arc-shaped reinforcing rib where it contacts the outer wall of the mounting plate.

[0010] As a preferred technical solution, the motor has ear plates on both outer walls, and the ear plates are detachably connected to the mounting plate by bolts.

[0011] As a preferred technical solution, a positioning seat is welded to the bottom of the square bar, and the positioning seat is fixedly connected to the metal frame at the rear of the tractor by bolts.

[0012] As a preferred technical solution, the inner wall of the frame is provided with multiple sets of rolling balls along its length, and the outer wall of the square bar is provided with ball grooves at positions corresponding to the rolling balls.

[0013] In summary, the present invention has the following main advantages:

[0014] This utility model achieves flexible adjustment of the height and angle of the pruning component by setting up a liftable load-bearing beam and a rotatable hydraulic motor, thereby adapting to the height and density changes of different shrub groups. The pruning component can be adjusted to a vertical state to prune the sides of the shrubs, so as to achieve comprehensive and precise pruning of the sides of the shrubs and ensure that the vegetation shape is neat and beautiful.

[0015] Furthermore, the three pruning components in this application improve pruning efficiency and reduce repetitive work time through the coordinated operation of the central disc and positioning tube, and avoid problems such as branch jamming and entanglement, thereby enhancing the operational stability and safety of the equipment and extending its service life.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] A shrubland greenbelt trimming device, such as Figures 1 to 6 As shown, it includes a square bar 100, and a load-bearing beam 110 that can be raised and lowered along its length is fitted on the outer wall of the square bar 100. A hydraulic motor 120 is rotatably connected to the end of the load-bearing beam 110. A second hydraulic rod 170 that can pull the hydraulic motor 120 to rotate into a vertical position is installed on the upper surface of the load-bearing beam 110. Three sets of trimming components 140 are provided below the hydraulic motor 120. The output end of the hydraulic motor 120 is provided with a tool that can pull the three sets of trimming components 140 to operate.

[0026] The output end of the hydraulic motor 120 is connected to a central plate 130. Three sets of positioning tubes 180 are installed on the outer wall of the central plate 130 along its circumference. The end of each set of positioning tubes 180 is welded with a mounting plate 182. Each set of pruning components 140 includes a motor 141 mounted on the outer wall of the mounting plate 182. The output end of the motor 141 is equipped with a saw disc 142 for shrub pruning.

[0027] The end of the load-bearing beam 110 is provided with a frame 111 that is sleeved on the outer wall of the square bar 100 and can slide up and down. The top of the load-bearing beam 110 is equipped with a first hydraulic rod 150 on the side near the square bar 100. The telescopic end of the first hydraulic rod 150 is fixed to the top of the square bar 100 by a plate.

[0028] The telescopic end of the second hydraulic rod 170 is rotatably mounted on the upper surface of the load-bearing beam 110, and the other end of the second hydraulic rod 170 is rotatably connected to a connecting plate 171. The end of the connecting plate 171 is rotatably connected to the outer wall of the hydraulic motor 120.

[0029] It is worth noting that the output end of the motor 141 is connected to the drive shaft 143 via a coupling. The saw disc 142 is precisely assembled onto the outer wall of the drive shaft 143 via a keyway and is fixed by an anti-slip nut 144. This effectively prevents it from loosening on its own under vibration and facilitates fastening or disassembly using special tools, making it convenient for subsequent replacement.

[0030] The hydraulic motor 120 consists of a motor and a housing, the top of which is provided with a removable cover plate;

[0031] The end of the load-bearing beam 110 is connected to the outer shell of the hydraulic motor 120 via a base 160;

[0032] A positioning seat 101 is welded to the bottom of the square bar 100, and the positioning seat 101 is fixedly connected to the metal frame at the rear of the tractor by bolts.

[0033] An outer cylinder 103 is fixed to the top of the positioning seat 101, and an inner shaft 104 fixed to the bottom of the square bar 100 is rotatably provided inside the outer cylinder 103.

[0034] The outer cylinder 103 is equipped with locking bolts that can tightly abut against the outer wall of the inner shaft 104. When the trimming device is not in working condition, the entire device can be stably positioned directly behind the tractor. This avoids potential interference and safety hazards that the trimming device may cause during road travel and ensures the smooth operation of the tractor. When trimming is required, the square bar 100 and the inner shaft 104 can rotate flexibly inside the outer cylinder 103, allowing the trimming assembly 140 to move smoothly to one side of the tractor, as shown in the attached instruction manual. Figure 1 As shown, the pruning assembly 140 is finally locked with a locking bolt, enabling it to perform efficient and convenient pruning of the bushes on the side of the tractor.

[0035] A generator is mounted on a metal frame, and the rotor at the end of the generator can be firmly connected to the power take-off shaft (PTO shaft) at the rear of the tractor, thereby driving the generator to perform efficient power generation through shaft rotation; the generated electrical energy is stably transmitted to the motor 141 through a voltage stabilizing circuit and cable system to provide it with continuous power so as to drive the pruning mechanism to complete the purpose of vegetation pruning.

[0036] In addition, the hydraulic motor 120 and the two sets of hydraulic rods are fully connected to the tractor's hydraulic oil tank through high-pressure oil pipes to form a complete hydraulic circuit, ensuring sufficient oil supply and thus providing reliable auxiliary power to enhance the cutting ability of the motor 141 and the saw disc 142, thereby efficiently pruning the bushes.

[0037] The tractor moves the device via a metal frame. The generator causes the motor 141 to start rotating. As the tractor moves forward, it can cut the shrubs in the green belt. At the same time, the output of the hydraulic motor 120 drives the three sets of pruning components 140 to revolve through the central plate 130. This allows the saw disc 142 to evenly cover the surface of the shrubs during the rotation and cutting process, effectively preventing branches from getting stuck or tangled in the gaps of the equipment. As it revolves, it can push the cut shrub branches to one side to facilitate subsequent manual cleaning.

[0038] By adjusting the lifting position of the load-bearing beam 110 on the square bar 100 using the first hydraulic rod 150, the tractor driver can flexibly control the horizontal height of the load-bearing beam 110 according to the operational needs, thereby adapting to the pruning requirements of shrubs of different heights; at the same time, the second hydraulic rod 170 pulls the hydraulic motor 120 to rotate to a vertical state, so that the three sets of pruning components 140 are arranged vertically with the load-bearing beam 110, thereby achieving comprehensive and precise pruning of the sides of the shrubs and ensuring that the vegetation shape is neat and beautiful.

[0039] The inner wall of the frame 111 is provided with multiple sets of rolling balls 112 along its length, and the outer wall of the square bar 100 is provided with ball grooves 102 at positions corresponding to the balls 112.

[0040] When the frame 111 and the square bar 100 move relative to each other, the ball 112 converts the traditional sliding friction into rolling friction through rolling action, reducing frictional resistance and improving the smoothness of movement and the durability of the component.

[0041] Please refer to this carefully. Figure 3 and Figure 5 An arc-shaped reinforcing rib 181 is welded between two adjacent sets of positioning tubes 180. The three sets of arc-shaped reinforcing ribs 181 form a ring-shaped reinforcing rib on the outer wall of the positioning tube 180. A reinforcing plate is welded at the end of the arc-shaped reinforcing rib 181 where it contacts the outer wall of the mounting plate 182.

[0042] The arc-shaped reinforcing rib 181 and the reinforcing plate structure enhance the connection strength between the positioning tube 180 and the mounting plate 182, reduce vibration and wear, and improve the stability of the device.

[0043] The reinforcing plate enhances the structural strength of the positioning tube 180 and the mounting plate 182, enabling them to better bear the weight of the motor 141 and ensuring the stability and safety of the overall structure.

[0044] Meanwhile, the wires connected to the motor 141 can be threaded through the positioning tube 180, avoiding the risk of damage to the wires due to exposure or friction during the trimming operation.

[0045] Please refer to this carefully. Figure 3 The outer walls on both sides of the motor 141 are provided with ear plates 145, which are detachably connected to the mounting plate 182 by bolts.

[0046] To facilitate the replacement of aging motor 141, bolts are used. A modular structure and quick-connect interface are adopted, which simplifies the disassembly and installation process of motor 141.

[0047] The parts of the device not covered herein are the same as or can be implemented using existing technologies.
