Description

Technical Field

[0001] This utility model relates to the technical field of landscaping equipment, specifically to a pruning device for landscaping projects. Background Technology

[0002] The trees and shrubs planted in green belts in gardens not only improve the environment but also serve as partitions and enhance the aesthetic appeal. Because the plants in green belts grow at different rates, they require regular pruning. Current pruning methods generally rely on manual labor. To maintain the aesthetic appeal of the green belts, the pruning must be done evenly, requiring professional pruning, thus increasing the cost of landscaping.

[0003] Patent document CN217241582U discloses a green belt pruning device for landscaping. This device, through the design of a support frame, allows for sliding installation of the connecting arms at both ends of the support frame onto guide rods on both sides of the top of the base via sliding holes. A threaded hole on the connecting arm in the middle of the rear side of the support frame is threaded onto a first threaded rocker rod rotatably mounted on the top of the base. Rotating the first threaded rocker rod allows for easy adjustment of the support frame's extension length, ensuring that the guide wheel mounted on the guide plate of the support frame contacts the side of the curb stone and provides guidance, facilitating smooth pruning of the green belt. The second electric pruning saw is designed so that its rear mounting block slides onto a guide groove on the outer surface of the base. A threaded hole on the mounting block at the rear end of the second electric pruning saw is threaded onto a second threaded rocker rod rotatably mounted within the guide groove on the outer surface of the base. Rotating the second threaded rocker rod allows for easy adjustment of its height, enabling the device to simultaneously prune the vertical sides and top surface of the green belt. However, in some green belts, trees are planted at intervals. When this device is pruning the plants in the green belt, it cannot properly avoid pruning the trees planted in the green belt, so it is inconvenient to use.

[0004] Patent document CN216650590U discloses a landscaping pruning device. This device allows the user to adjust the pruning depth by rotating a turntable, then activates a motor. The motor drives blades to evenly prune the trees, addressing the problems of low efficiency and potential damage to saplings associated with manual lawn mowing. However, when pruning plants in greenbelts, this device cannot effectively avoid pruning the upper parts of the plants, resulting in inconvenience in its use. Utility Model Content

[0005] The main purpose of this utility model is to provide a pruning device for landscaping projects that can stagger the trees planted in the green belt and prune the upper part of most of the plants in the green belt during a single linear movement.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: A pruning device for landscaping projects includes a base plate with multiple wheels mounted on its lower end. A lifting assembly is fixed to the upper front side of the base plate, and a horizontally positioned upper plate is fixed to the upper end of the lifting assembly. A rope-releasing wheel is elastically rotatably connected to the upper end of the upper plate, with its axis perpendicular to the upper plate. A hedge trimmer is mounted above the rope-releasing wheel, comprising a drive unit and a cutting unit. The drive unit of the hedge trimmer is detachably and fixedly connected to the upper end of the rope-releasing wheel. The length direction of the cutting unit of the hedge trimmer is perpendicular to the movement direction of the base plate. A first stop bar is fixed to the upper end of the upper plate in front of the drive unit of the hedge trimmer, and the first stop bar affects the drive unit of the hedge trimmer. The front side of the hedge trimmer is blocked. A second stop is fixed at the upper end of the upper plate behind the drive unit of the hedge trimmer. After the rope release wheel drives the hedge trimmer to rotate counterclockwise, the second stop can block the drive unit of the hedge trimmer. A push rod is fixed at the upper end of the rear side of the base plate. A rope take-up wheel is concentrically mounted on the push rod. The rope take-up wheel and the rope release wheel are connected by a pull rope. The pull rope is wound around the rope take-up wheel. A rotating sleeve is concentrically fixed on one side of the rope take-up wheel. The rotating sleeve is rotatably connected to the push rod. An outer spline sleeve is concentrically fixed on the other side of the rope take-up wheel. An inner spline sleeve is connected to the inner spline sleeve. The inner spline sleeve is slidably mounted on the outside of the push rod. The inner spline sleeve is splinedly connected to the push rod.

[0007] Specifically, the lifting assembly includes a square sleeve, which is vertically arranged. The lower end of the square sleeve is fixedly connected to the base plate. A square tube is slidably arranged inside the square sleeve. The upper plate is fixed to the upper end of the square tube. A locking bolt is threadedly connected to the square sleeve, and the locking bolt is tightly pressed against the square tube.

[0008] Specifically, the axle of the rope-releasing wheel is rotatably connected to the upper plate, and the rope-releasing wheel is connected to the upper plate through a torsion spring. One end of the torsion spring is fixedly connected to the rope-releasing wheel, and the other end of the torsion spring is fixedly connected to the upper plate.

[0009] Specifically, multiple guide members are installed on one side of the base plate below the hedge cutting unit, and the multiple guide members are linearly arrayed in the traveling direction of the base plate; the guide members include ear seats fixed to the side end of the base plate, and guide wheels are rotatably connected inside the ear seats.

[0010] Specifically, the push rod is fixedly connected to the base plate through a support frame, the push rod is set horizontally, and the axial direction of the push rod is perpendicular to the traveling direction of the base plate.

[0011] Specifically, the square sleeve and the base plate are fixedly connected by diagonal bracing.

[0012] Specifically, a groove is provided on the bottom plate on the rear side of the lifting assembly.

[0013] Specifically, the drive unit of the hedge trimmer is fixed with multiple mounting bases, and the mounting bases are fixedly connected to the rope release wheel by fastening bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Operators only need to push this device to move in a straight line along the green belt to trim the upper part of the plants in the green belt, which greatly reduces the labor intensity of manually holding the machine. The cutting unit of the hedge trimmer is arranged perpendicular to the direction of travel, which ensures that most of the green belt area can be trimmed at one time during continuous travel, reducing repetitive operations.

[0015] 2. The adjustable lifting component supports rapid height adjustment of the hedge trimmer. By adjusting the height of the square tube, the cutting position can be precisely controlled to adapt to different plant growth patterns and ensure the flatness of the trimmed surface.

[0016] 3. After separating the inner spline sleeve and the outer spline sleeve, the torsion spring drives the rope release wheel to rotate automatically counterclockwise, causing the cutting unit to tilt and avoid the tree. At the same time, the second stop lever limits the angle to ensure safety.

[0017] 4. The guide wheels are designed to assist in stable movement along the roadside stones and prevent the device from deviating during operation.

[0018] 5. Rotate the rope take-up wheel to tighten the rope. The hedge trimmer will be stopped and reset by the first stop bar. After the inner spline sleeve is locked back into the outer spline sleeve, it can resume operation. It is easy to operate.

[0019] 6. The hedge trimmer can be quickly fixed to the rope release wheel via the mounting base and fastening bolts, and is easy to disassemble.

[0020] 7. The limiting system of the first and second stops ensures the structural stability of the equipment during operation or obstacle avoidance, and reduces the impact of vibration on trimming accuracy.

[0021] 8. The grooved base plate design reduces overall weight and improves maneuverability. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1: Refer to Figures 1-3 As shown, a pruning device for landscaping projects includes a base plate 1, with multiple rotating wheels 17 installed at the lower end of the base plate 1, a lifting assembly fixed at the upper front side of the base plate 1, and a horizontally arranged upper plate 11 fixed at the upper end of the lifting assembly.

[0028] The lifting assembly includes a square sleeve 18, which is vertically positioned. The lower end of the square sleeve 18 is fixedly connected to the base plate 1, and the square sleeve 18 and the base plate 1 are fixedly connected by a diagonal brace 15. A square tube 19 is slidably disposed inside the square sleeve 18, and an upper plate 11 is fixed to the upper end of the square tube 19. A locking bolt 20 is threaded onto the square sleeve 18, and the locking bolt 20 is tightly pressed against the square tube 19. Loosening the locking bolt 20 allows the height of the square tube 19 to be adjusted. After the height of the square tube 19 is adjusted, the locking bolt 20 can position the square tube 19.

[0029] A groove 16 is provided on the base plate 1 at the rear of the lifting assembly. By providing the groove 16 on the base plate 1, the weight of the base plate 1 can be reduced, thereby reducing the overall weight of the device.

[0030] The upper end of the upper plate 11 is elastically rotatably connected to a rope release wheel 12, and the axis of the rope release wheel 12 is perpendicular to the upper plate 11.

[0031] The axle of the rope release wheel 12 is rotatably connected to the upper plate 11, and the rope release wheel 12 is connected to the upper plate 11 by a torsion spring. One end of the torsion spring is fixedly connected to the rope release wheel 12, and the other end of the torsion spring is fixedly connected to the upper plate 11.

[0032] A hedge trimmer 14 is mounted on the upper end of the rope-feeding reel 12. The hedge trimmer 14 includes a drive unit and a cutting unit. The drive unit of the hedge trimmer 14 is detachably and fixedly connected to the upper end of the rope-feeding reel 12. Specifically, multiple mounting seats 13 are fixed on the drive unit of the hedge trimmer 14, and the mounting seats 13 are fixedly connected to the rope-feeding reel 12 by fastening bolts.

[0033] The length direction of the cutting unit of the hedge trimmer 14 is perpendicular to the movement direction of the base plate 1.

[0034] A first stop bar 21 is fixed to the upper end of the upper plate 11 on the front side of the drive unit of the hedge trimmer 14. The first stop bar 21 blocks the front side of the drive unit of the hedge trimmer 14. A second stop bar 22 is fixed to the upper end of the upper plate 11 on the rear side of the drive unit of the hedge trimmer 14. After the rope release wheel 12 drives the hedge trimmer 14 to rotate counterclockwise, the second stop bar 22 can block the drive unit of the hedge trimmer 14.

[0035] A push rod 3 is fixed to the upper rear side of the base plate 1. The push rod 3 is fixedly connected to the base plate 1 through the support frame 2. The push rod 3 is set horizontally, and the axial direction of the push rod 3 is perpendicular to the travel direction of the base plate 1.

[0036] A take-up rope wheel 8 is concentrically mounted on the push rod 3. The take-up rope wheel 8 is connected to the release rope wheel 12 via a pull rope 10, with part of the pull rope 10 wound around the take-up rope wheel 8. A rotating sleeve 9 is concentrically fixed on one side of the take-up rope wheel 8, and the rotating sleeve 9 is rotatably connected to the push rod 3. An outer spline sleeve 7 is concentrically fixed on the other side of the take-up rope wheel 8. An inner spline sleeve 6 is splinedly connected to the inner side of the outer spline sleeve 7. The inner spline sleeve 6 is slidably fitted on the outside of the push rod 3, and the inner spline sleeve 6 is splinedly connected to the push rod 3.

[0037] When this device is working, the drive unit of the hedge trimmer 14 is fixedly connected to the upper end of the rope release wheel 12 through the cooperation of the mounting base 13 and the fastening bolt. Then, the inner spline sleeve 6 moves along the axial direction of the push rod 3 and separates the inner spline sleeve 6 from the outer spline sleeve 7. The rope take-up wheel 8 is rotated by the rotating sleeve 9, and the rope take-up wheel 8 winds the pull rope 10, and the rope release wheel 12 is tightened. At the same time, the first stop rod 21 blocks the drive unit of the hedge trimmer 14. Finally, the inner spline sleeve 6 and the outer spline sleeve 7 are splined together, and the hedge trimmer 14 is stabilized.

[0038] Start the drive unit of the hedge trimmer 14. The drive unit of the hedge trimmer 14 drives the cutting unit of the hedge trimmer 14 to move. The push rod 3 pushes the device to move along the extension direction of the green belt. The cutting unit of the hedge trimmer 14 can trim the upper part of the plants in the green belt.

[0039] By adjusting the height of the square tube 19, the height of the hedge trimmer 14 can be adjusted, thereby adjusting the cutting height of the upper part of the plants in the green belt.

[0040] When it is necessary for the cutting unit of the hedge trimmer 14 to be offset from the trees planted in the green belt, the inner spline sleeve 6 moves along the axial direction of the push rod 3, causing the inner spline sleeve 6 to separate from the outer spline sleeve 7. After the inner spline sleeve 6 separates from the outer spline sleeve 7, under the elastic force of the torsion spring, the rope release wheel 12 drives the hedge trimmer 14 to rotate counterclockwise. The rope release wheel 12 winds up the pull rope 10, and the pull rope 10 on the rope take-up wheel 8 is unwound. When the second stop lever 22 blocks the drive unit of the hedge trimmer 14, the state of the hedge trimmer 14 is as follows. Figure 3 As shown, at this time, the cutting unit of the hedge trimmer 14 is tilted, and the cutting unit of the hedge trimmer 14 can avoid the trees planted in the green belt during the process of moving.

[0041] When the cutting unit of the hedge trimmer 14 moves to the front of the trees planted in the green belt, the winding wheel 8 is rotated by the rotating sleeve 9. The winding wheel 8 winds the pull rope 10. After the release wheel 12 is tightened, the first stop 21 blocks the drive unit of the hedge trimmer 14. At this time, the hedge trimmer 14 is reset, and then the inner spline sleeve 6 and the outer spline sleeve 7 are splined together. The hedge trimmer 14 is stabilized again and can be pushed forward to continue moving.

[0042] This device allows for easy navigation around trees planted in the green belt during its movement, and can trim the tops of most plants within the green belt in a single straight-line motion. Using this device only requires adjusting the height of the hedge trimmer 14 before pushing it along the direction of the green belt to trim the tops of the plants. It requires minimal technical skill from the user, and its stable movement enhances the stability of the hedge trimmer 14, resulting in a smoother trim of the plants within the green belt.

[0043] After this device trims the tops of most of the plants in the green belt, other hedge trimmers 14 can be used to trim the tops of the plants near the trees in the green belt.

[0044] Example 2: Based on Example 1, referring to... Figures 1-3 As shown, multiple guide members are installed on one side of the base plate 1 below the cutting unit of the hedge trimmer 14. The multiple guide members are linearly arranged in the traveling direction of the base plate 1. The guide members include ear seats 4 fixed to the side end of the base plate 1, and guide wheels 5 are rotatably connected inside the ear seats 4.

[0045] In this embodiment, a guide wheel 5 is provided. When there is a curb stone 23 at the edge of the green belt, the guide wheel 5 can roll into contact with the side of the curb stone 23 of the green belt during the process of pushing the device to move along the extension direction of the green belt. This improves the stability of the device during the movement along the extension direction of the green belt, avoids deviation of the device during the movement, and improves the ease of operation of the device.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
