Description

Technical Field

[0001] The utility model provides a road greening pruning device, which relates to the technical field of greening pruning devices. Background Art

[0002] In the process of rapid economic development, along with the large-scale construction of roads, it also brings about the damage of road construction projects to the ecological environment. In order to repair the disruption of the ecological system caused by road lines, the damage to the environment caused by road construction, and the impact of road traffic on the environment, people have been studying and practicing the theory, technology and methods of road greening for a long time, making road greening a relatively independent discipline. Road greening (roadplanting) refers to the planting of trees, flowers and plants on both sides or in the middle of the road, with the purpose of improving the traffic environment.

[0003] In the process of road greening, the most common greening work is to trim the green plants on both sides of the road. When trimming some larger green areas, sometimes the staff needs to step into the green belt to trim to a position closer to the inside, which is extremely inconvenient. The existing trimming devices are usually only equipped with one trimming head, and the trimming range of a single trimming head is limited. For trimming in a large area, the staff needs to go back and forth multiple times for trimming, resulting in low trimming efficiency. Even if some trimming devices are improved to retractable structures, the trimming heads can be extended deeper and the staff do not need to step into the green area for operation, but due to the limited trimming range of a single trimming head, it is still necessary to trim the green plants on the outside first, and then use the telescopic structure to extend the trimming head into the depth of the green area for trimming. It still requires multiple operations to complete the trimming, and the efficiency is not effectively improved. For this reason, we propose a road greening trimming device. Utility Model Content

[0019] The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0020] Reference Figures 1 to 4 The utility model provides a road greening pruning device, including a pruning assembly 11, the pruning assembly 11 is connected to a telescopic bracket, the telescopic bracket is connected to a walking chassis 1, the telescopic bracket includes a lifting arm 4 and a rotating arm 10 hinged at one end of the lifting arm 4, the lifting arm 4 is L-shaped, the rotating arm 10 is arranged at the short side end of the lifting arm 4, the lifting arm 4 is close to the bottom of the rotating arm 10, and the output shaft of the second motor 16 is fixed to the end of the rotating arm 10. Specifically, the rotating arm 10 can be driven to rotate by the second motor 16, so that the telescopic bracket can be moved from Figure 4 The state is extended to Figure 2 state, so that when it is necessary to trim deeper, the trimming range can be expanded by extending the telescopic bracket.

[0021] Furthermore, if Figure 1 As shown, in the utility model, the top of the lifting arm 4 is fixedly connected with a first reinforcing rod 8, the top of the rotating arm 10 is fixedly connected with a second reinforcing rod 9, and the end of the first reinforcing rod 8 and the end of the second reinforcing rod 9 are hinged to each other. Specifically, the structure of the telescopic bracket is reinforced by the first reinforcing rod 8 and the second reinforcing rod 9, so that the telescopic bracket structure is more stable and reliable.

[0022] Furthermore, if Figure 1 As shown, the traveling chassis 1 of the utility model is fixedly connected with a hydraulic cylinder 3 and a sleeve 2, the telescopic end of the hydraulic cylinder 3 is fixedly connected with the end of the lifting arm 4, the sleeve 2 is provided with two and symmetrically arranged on both sides of the hydraulic cylinder 3, the sleeves 2 are slidably connected with guide rods 5, the top of the guide rods 5 is fixedly connected with the lifting arm 4, and the traveling chassis 1 is provided with an electric control box 6. Specifically, the lifting arm 4 can be driven to be lifted and lowered by the extension and retraction of the hydraulic cylinder 3, and when the lifting arm 4 is lifted and lowered, the guide rod 5 slides in the sleeve 2 to guide the lifting and lowering of the lifting arm 4, so that the lifting process is more stable.

[0023] It should be noted that the traveling chassis 1 and the electric control box 6 are both based on the existing technology, which is well known to those skilled in the art, and thus will not be described in detail.

[0024] Furthermore, if Figure 2 , Figure 3 As shown, the trimming assembly 11 in the utility model includes a rotating shaft 13 arranged at equal intervals, a trimming head 12 coaxially fixed to the bottom end of the rotating shaft 13, and a sprocket 14 and a chain 15 connected between the rotating shafts 13. The trimming assembly 11 is provided with two, and is respectively provided at the bottom of the lifting arm 4 and the rotating arm 10. Specifically, a plurality of trimming heads 12 are provided in the trimming assembly 11, so that the range width of one-time trimming is multiplied, thereby multiplying the work efficiency. After the telescopic bracket is extended and retracted, the two groups of trimming assemblies 11 trim the green plants inside and outside at the same time. Compared with the traditional trimming device that trims the outside first before trimming the deep green plants, the present device can trim at the same time, which is more efficient.

[0025] Furthermore, if Figure 2 , Figure 3 As shown, the rotating shaft 13 in the utility model is rotatably connected with the telescopic bracket, and three rotating shafts 13 are equidistantly arranged. Sprockets 14 are coaxially fixed on the rotating shafts 13, and the number of sprockets 14 on the middle rotating shaft 13 is 2, and the number of sprockets 14 on the rotating shafts 13 on both sides is 1, and the sprockets 14 are connected between two adjacent sprockets 14 on the left and right.

[0026] Working principle: Start the first motor 7 to drive the trimming assembly 11 to operate, and use multiple pruning heads 12 to trim the green plants at the same time, so that the trimming range is larger and the efficiency is better. When the greening area is relatively wide, start the second motor 16 to drive the rotating arm 10 to rotate 180 degrees clockwise, extend the length of the telescopic bracket, and make the two groups of trimming assemblies 11 change from front and back side by side to left and right adjacent positions, thereby further expanding the trimming range. When trimming, the two groups of trimming assemblies 11 trim the green plants inside and outside at the same time, without the need to make multiple trips back and forth for trimming, which is more efficient.

[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
