Description

Technical Field

[0001] This application relates to the field of greening pruning, and more particularly to a road greening pruning device. Background Art

[0002] Landscaping is not only a way to increase the greening area and purify the air today, but also a project that reflects garden design, parks, communities, and even the urban image. Currently, greening is widely used in urban construction, road greening, and the isolation belt greening of expressways. With the continuous expansion of the types and areas of current greening, the workload of garden restoration and maintenance is also increasing. In order to achieve the purpose of high-efficiency and high-quality garden maintenance, the current pruning and maintenance methods have transitioned from the initial manual tool pruning to the semi-automatic pruning of electric tools and internal combustion engine tools.

[0003] The patent document with the publication number CN219536923U discloses a road greening pruning device. This utility model discloses a road greening pruning device, belonging to the field of pruning road greening plants. A road greening pruning device includes a base. A lifting column is arranged on the top of the base. A telescopic rod is arranged on the top of the lifting column. A rotating rod is arranged at the end of the telescopic rod. A first mounting plate is arranged at the bottom of the rotating rod. A second mounting plate is arranged on the lower surface of the first mounting plate. A pruning knife is installed at the bottom of the second mounting plate. A first movable block is movably connected to the lower surface of the first mounting plate on one side of the second mounting plate. The bottom of the first movable block is rotatably connected to a side plate. A third mounting plate is movably connected to the inner side surface of the side plate. In the above application document, three groups of pruning knives located above and on the left and right sides are adjusted through the lifting column and the telescopic rod, so that they cover the green belt and perform pruning during the moving process. However, there are pruning dead corners in the setting between the three groups of pruning knives. When it is necessary to prune green belts of different specifications, if the pruning knives on the left and right sides are adjusted, gaps will be generated with the pruning knives located above, which is not convenient for comprehensively pruning the green belt.

[0022] See Figures 1-4, this embodiment provides a road greening pruning device, including a base 1, which is used to be installed on a vehicle body. A first telescopic rod 2 is fixedly connected above the base 1. The upper end of the first telescopic rod 2 is fixedly connected with a connecting block 3. A second telescopic rod 4 is fixedly connected to the left side of the connecting block 3. Both the first telescopic rod 2 and the second telescopic rod 4 can be telescopically adjusted and fixed in length, which is prior art. A connecting column 5 is fixedly connected below the second telescopic rod 4. A pruning assembly 6 is arranged below the connecting column 5. The pruning assembly 6 includes a mounting plate 601, and the mounting plate 601 is fixedly connected to the lower part of the connecting column 5. A second sprocket 602 is rotatably connected below the mounting plate 601. A first sprocket 604 is drivingly connected to the left side of the second sprocket 602 through a chain 603. The chain 603 is provided with blades for shearing. The chain 603 is driven to drive the blades to sweep over the green belt, thereby pruning the green belt. The pruning assembly 6 further includes a support base 605, and the support base 605 is fixedly connected above the mounting plate 601. The support base 605 supports and fixedly connects a motor 606, and the output end of the motor 606 faces downward. The output end of the motor 606 is fixedly connected with a rotating shaft 607 through a coupling. The rotating shaft 607 penetrates and is rotatably connected above the mounting plate 601. A bearing is arranged between the rotating shaft 607 and the mounting plate 601. The rotating shaft 607 is fixedly connected above the first sprocket 604. A pruning device 7 is arranged on the front surface of the mounting plate 601. The number of pruning devices 7 is two. The pruning device 7 includes a protective cover, and a structure such as the chain 603 with blades in the pruning assembly 6 is arranged in the protective cover for pruning the greening.

[0023] When the above device is specifically used, first install the base 1 on the vehicle body, and then adjust the first telescopic rod 2 and the second telescopic rod 4 to place the chain 603 above the green belt. At this time, start the pruning device 7 and the motor 606. The motor 606 drives the rotating shaft 607 to rotate to make the first sprocket 604 rotate. The rotation of the first sprocket 604 will drive the chain 603 to make the second sprocket 602 rotate. The chain 603 will be driven between the first sprocket 604 and the second sprocket 602. The chain 603 is driven to drive the blades to sweep over the green belt, thereby pruning the upper part of the green belt. At this time, the pruning device 7 will prune the side of the green belt. Embodiment

[0024] See Figures 1-4, on the basis of the first embodiment, a sliding assembly 8 is provided behind the trimming device 7. The sliding assembly 8 includes an electric slide rail 801. Limit structures are provided at the left and right ends of the electric slide rail 801 to prevent the slider 802 from disengaging. The electric slide rail 801 is fixedly connected to the front surface of the mounting plate 601. The electric slide rail 801 can drive the slider 802 to slide left and right, which is prior art. The front surface of the electric slide rail 801 is slidably connected to the slider 802. The number of sliders 802 is two. An adjusting assembly 9 is provided below the slider 802. The number of adjusting assemblies 9 is two groups, which are respectively arranged on the two trimming devices 7. The adjusting assembly 9 includes a support piece 901. The support piece 901 is fixedly connected to the rear of the trimming device 7. A screw rod 902 is rotatably connected above the support piece 901. The screw rod 902 passes through the upper part of the slider 802 in a threaded manner. A threaded through hole adapted to the screw rod 902 is provided above the slider 802. The slider 802 is slidably connected to the outer surface of the trimming device 7. A chute is provided on the outer surface of the trimming device 7 for sliding within the slider 802.

[0025] When the above device is specifically used, when it is necessary to trim green belts of different specifications, the electric slide rail 801 can drive the two sliders 802 to slide towards or away from each other to adjust the distance between the two trimming devices 7, so as to adapt to green belts of different widths. By rotating the screw rod 902, the support piece 901 is driven to make the trimming device 7 slide up and down within the slider 802, thereby adjusting the height of the trimming device 7 to facilitate adapting to green belts of different heights. The trimming device 7 will always be staggered with the chain 603 during adjustment, achieving the effect of preventing trimming dead corners.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
