Description

Technical Field

[0001] The invention relates to the field of hedge trimming tools, in particular to a garden green plant trimming device. Background Art

[0002] With the acceleration of urbanization and the improvement of people's requirements for garden quality, low green plants, mainly shrubs, are planted in large quantities in parks and on both sides of urban roads. Due to the rapid growth of low green plants and the need for gardening shapes, they need to be pruned frequently, mainly including top surface pruning, arc surface pruning, and shape pruning. At present, since garden pruning tools are mainly for tall trees, there are few special pruning tools and designs for low green plants, so there are the following problems.

[0003] 1. Pruning is basically done by manual scissors, which is labor-intensive and causes fatigue to the operator.

[0004] 2. There is a lack of control over branches during pruning. The branches are prone to shaking during the pruning process, and there is a certain amount of space between the branches, resulting in low pruning efficiency.

[0005] 3. There is a lack of standard control during the pruning process, and it is difficult to achieve precise pruning shapes relying solely on manual operation. Summary of the invention

[0006] In order to overcome the problems of existing garden pruning tools in pruning low green plants, such as high work intensity, low pruning efficiency, and difficulty in precise shaping, the present invention provides a garden green plant pruning device, which is characterized by comprising four parts: a transfer vehicle, a top surface pruner, a curved surface pruner, and a fine pruner.

[0007] 1. The transfer vehicle consists of three parts: a base, a bottom plate, and rotating wheels.

[0008] The base is located on the upper part of the base plate and is a rectangular parallelepiped, divided into three parts longitudinally. Each part is connected to the top surface trimmer, arc trimmer, and fine trimmer through a lifting mechanism. The middle part is controlled by a hydraulic system to adjust the height and angle of each trimmer. The bottom end of the base is connected to the movable rail of the base plate and can be moved.

[0009] The bottom plate is equipped with an electric motor and a generator, and has multiple movable rails in the horizontal direction. The bottom is connected to rotating wheels, and the top is connected to a base.

[0010] There are multiple rotating wheels made of rubber, with a spherical cavity at the center, which are installed on two sides of the base plate, and the outer walls are radially connected to multiple supporting legs.

[0011] 2. The top trimmer consists of four parts: an outer cover, a combing cylinder, a cutting blade, and a storage container.

[0012] The outer cover is a trapezoidal body, with the top and side surfaces closed and the bottom surface open, and the interior accommodates a combing cylinder, a shearing blade, and a storage container. The outer cover is connected to the base through a lifting mechanism.

[0013] The carding cylinder is cylindrical, connected to the rotating shaft horizontally, and connected to the flat push side strips on the outside. Driven by the motor, the rotating shaft drives the carding cylinder to rotate counterclockwise, and the rotation frequency of the carding cylinder is synchronized with the movement of the shearing blade.

[0014] The shearing blade is divided into two parts: a fixed blade and a cross-cutting blade. The fixed blade is rectangular as a whole, with a continuous V-shaped outer edge, adjacent to the push edge strip; the cross-cutting blade is strip-shaped as a whole, with serrated edges, and is controlled by a motor. Its serrations make a linear reciprocating motion along the V-shaped edge of the fixed blade.

[0015] The receiver is located on the opposite side of the combing cylinder and uses vacuum suction equipment to form a strong adsorption airflow.

[0016] 3. The curved trimmer consists of four parts: a hanger, a slide rail, a shear wheel, and a fixed frame.

[0017] The hanger is arc-shaped, and the top is connected to the lifting mechanism of the base. Under the adjustment of the lifting mechanism, it can not only move up and down, but also rotate 360 ​​degrees. The hanger is divided into multiple units, with rotating shafts between the units. There are hydraulic push rods at the top and bottom. Through the control system operation, the extension and retraction of different push rods between the units can be realized, so as to adjust the hanger to a variety of arcs.

[0018] The slide rail is a long elastic metal strip, the top surface of which is connected to the bottom of the hanger, and the bottom surface has a groove that changes with the curvature of the hanger.

[0019] The shear wheel is divided into two parts: a fixture and a rotary cutter. The upper part of the fixture is connected to the slide rail, and the lower part is connected to the rotary cutter. Under the operation of the control system, the fixture slides back and forth along the groove of the slide rail. The rotary cutter is cylindrical with a metal cover on the outside and an opening at the bottom. There is a rotating shaft inside the cover that is connected to the cutting tool. The motor drives the rotating shaft to rotate, and the cutting tool performs cutting action at the opening.

[0020] The fixed frame is an elastic metal mesh, which is connected to hangers on both sides and is rectangular. The diameter of the mesh wire in the middle of the mesh is larger than that on both sides. It is below the shearing wheel and maintains a fixed distance with the shearing wheel.

[0021] 4. The fine trimmer is rectangular in shape and is divided into two layers, the upper layer is the controller and the lower layer is the fixing frame.

[0022] The controller consists of three parts: a frame, a sliding rod, and a cutting drill. An electronic device is installed inside the frame. After the operation command is input, the electronic device receives the design data and converts it into instructions for controlling the pruning operation. The frame is connected to the sliding rod. After receiving the operation instruction, the sliding rod moves at a constant speed. The cutting drill is connected to the controller by a data cable. The top of the cutting drill is a telescopic device. The telescopic device runs along the sliding rod and adjusts the length of the cutting drill according to the design data. The end is a trapezoidal drill bit. After the input program is started, the cutting drill rotates according to the design data route and depth to prune branches within the set range.

[0023] The fixed frame consists of three parts: a lifter, a mesh plate, and a pressure plate. The four corners of the lifter are connected to the controller. Driven by the motor, it performs two actions: rising and falling. The lifter is connected to the mesh plate by bolts. The mesh plate is divided into various specifications such as arc surface and flat surface, and can be replaced according to the work task. There are fine circular holes distributed on the surface of the mesh plate, and the pressure plate is connected around the circular holes. The pressure plate encloses the circular holes in the shape of lotus petals, and the bottom of the pressure plate is connected to a spring.

[0024] The positive effects of the present invention are as follows: the labor intensity of pruning green plants can be effectively reduced, while achieving the purpose of improving pruning efficiency and accurate shaping. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0043] Figure 1 As shown, the present invention comprises four parts, namely, a transfer vehicle 1, a top surface trimmer 2, a curved surface trimmer 3, and a fine trimmer 4, and their relative positional relationships.

[0044] Figure 2 As shown, the transfer vehicle 1 includes three parts: a base 5, a bottom plate 6, and a rotating wheel 7. The base 5 is located on the upper part of the bottom plate 6 and is a rectangular parallelepiped, which is divided into three parts longitudinally. The middle part is controlled by a hydraulic system to adjust the height and angle of each trimmer. The bottom end of the base 5 is connected to the movable rail of the bottom plate 6, and the position can be moved; the bottom plate 6 is equipped with an electric motor and a generator, and there are multiple movable rails in the horizontal direction; the rotating wheel 7 is made of rubber and installed on both sides of the bottom plate 6. The center position is a spherical cavity, and the outer wall is radiantly connected to multiple support frames. When the rotating wheel 7 passes through a raised road surface, the support frame shrinks to the center position, and the height difference between the raised road surface and the horizontal road surface is offset by the middle cavity of the rotating wheel 7, which has a small overall impact on the balance of the bottom plate 6, thereby providing a foundation for the smooth operation of the pruning tools.

[0045] Figure 3 As shown, the top trimmer 2 includes four parts: an outer cover 8, a combing cylinder 9, a storage container 10, and a shearing blade 12.

[0046] The outer cover 8 is a trapezoidal body, with the top and side surfaces closed and the bottom surface open, and the interior accommodates the combing cylinder 9, the storage container 10, and the shearing blade 12. The outer cover 8 is connected to the base 5 through a lifting mechanism.

[0047] The combing cylinder 9 is cylindrical, connected to a rotating shaft inside and a push side strip 11 outside. Driven by the motor, the rotating shaft drives the combing cylinder 9 to rotate counterclockwise, and the push side strip 11 moves and fixes the top branches of the green plants to concentrate on the shearing blade 12. The rotation frequency of the combing cylinder 9 is synchronized with the movement of the shearing blade 12.

[0048] The storage device 10 is located on the opposite side of the combing cylinder 9, and adopts a vacuum suction device to form a strong adsorption airflow to suck the cut branches 15 into the storage device, further reducing the work intensity.

[0049] Figure 4 As shown, the shear blade 12 is divided into a fixed blade 13 and a cross-cutting blade 14. The fixed blade 13 is rectangular in shape and has a continuous V-shaped outer edge close to the flat push edge strip 11 of the combing cylinder 9. The cross-cutting blade 14 is above the fixed blade 13 and is driven by the motor. During operation, the branches moved by the flat push edge strip 11 enter the V-shaped angle of the fixed blade 13 to fix the trimmed branches 15; the cross-cutting blade 14, driven by the motor, moves back and forth along the V-shaped outer edge of the fixed blade 13 to cut off the branches 15 pressed by the flat push edge strip 11 and the fixed blade 13.

[0050] Figure 5 As shown, the curved trimmer 3 includes four parts: a hanger 16, a slide rail 17, a shearing wheel 18, and a fixing frame 19.

[0051] The hanger 16 is arc-shaped, and the top end is connected to the lifting mechanism of the base 5. Under the adjustment of the lifting mechanism, it can not only move up and down, but also rotate 360 ​​degrees. The hanger 16 is divided into multiple units, and there are rotating shafts between the units. The top and bottom ends of the hanger 16 are respectively provided with hydraulic push rods. Through the control system operation, the push rods between the units are extended and retracted, and the hanger 16 is adjusted to a variety of arcs.

[0052] The slide rail 17 is a long elastic metal strip, the top surface of which is connected to the bottom of the hanger 16 , and the bottom surface has a groove that changes with the curvature of the hanger 16 .

[0053] The shear wheel 18 is divided into two parts: a fixing device 20 and a rotary cutter 21 . The upper part of the fixing device 20 is connected to the slide rail 17 , and the lower part is connected to the rotary cutter 21 .

[0054] The fixed frame 19 is an elastic metal mesh, connected to the hanger 16 on both sides, and is rectangular. The diameter of the mesh in the middle of the mesh is larger than that on both sides, and it is below the shearing wheel 18, and a fixed distance is maintained between the shearing wheel 18. By adjusting the height of the hanger 16, the fixed frame 19 is attached to the top of the green plant, and the branches 15 at the top of the green plant that are higher than the fixed frame 19 are limited by the metal mesh. After setting the curvature of the hanger 16, the curvatures of the slide rail 17 and the fixed frame 19 are synchronized in place, and the shearing wheel 18 is started. The shearing wheel 18 reciprocates along the slide rail 17 and cuts at a set height above the fixed frame 19, forming a regular arc surface on the top of the green plant. After completing the arc surface trimming of an area, adjust the angle of the lifting mechanism, and the hanger 16 rotates to enter the operation of the next arc surface area.

[0055] Figure 6 As shown, the fixture 20 on the upper part of the shearing wheel 18 slides back and forth along the groove of the slide rail 17 under the command of the control system. The rotary cutter 21 is cylindrical, with a metal cover 22 on the outside and an opening at the bottom. There is a rotating shaft inside the cover 22, which is connected to the cutting tool. The motor drives the rotating shaft to rotate, and the cutting tool performs a cutting action at the opening to complete the pruning of the branches 15 defined on the fixed frame 19.

[0056] Figure 7 As shown, the fine trimmer 4 is rectangular in shape and is divided into two layers, the upper layer is the controller, and the lower layer is the fixed frame. The controller includes three parts: a frame 23, a sliding rod 24, and a cutting drill 25. The frame 23 is equipped with electronic equipment. After the operation command is input, the controller receives the design data and converts it into a pruning operation instruction. The controller is connected to the sliding rod 24. After receiving the operation instruction, the sliding rod 24 moves at a constant speed. The cutting drill 25 is connected to the controller by a data line. The top of the cutting drill 25 is a telescopic device. The telescopic device runs along the sliding rod 24. The length of the cutting drill 25 is set and adjusted according to the design data. The end is a trapezoidal drill bit. After receiving the command of the controller, the cutting drill 25 rotates according to the design data route and depth after the input program is started, and the branches 15 within the set range are trimmed. Through the data setting of the controller and the trapezoidal structure of the cutting drill 25, the cutting is carried out more accurately at the trimming position, and a more regular text and pattern shape is obtained on the surface of the green plant.

[0057] Figure 8As shown, the fixing frame includes three parts: a lifter 26, a mesh plate 27, and a pressing piece 28. The lifter 26 is connected to the four corners of the controller. Driven by the motor, it performs two actions: rising and falling. The lifter 26 is connected to the mesh plate 27 by bolts. The mesh plate 27 is divided into various specifications such as arc surface and plane surface. It is replaced according to the task. The surface of the mesh plate 27 is distributed with fine and dense round holes. The periphery of the round hole is connected with the pressing piece 28. The pressing piece 28 surrounds the round hole in the shape of a lotus petal. The bottom of the pressing piece 28 is connected with a spring 29. Through control, the lifter 26 descends to press the surface of the green plant. After the top branch 15 of the green plant hits the pressing piece 28, it extends out from the round hole of the mesh plate 27. The spring 29 at the bottom of the pressing piece 28 applies force to pull the pressing piece 28 to tighten. The branch 15 is relatively stably fixed at the position of the round hole, providing good working conditions for pruning.
