Description

Technical Field

[0001] The utility model relates to the technical field of highway greening pruning, in particular to a highway greening pruning device. Background Art

[0002] Highway greening trimming device is a mechanical device designed for highway green belts, which aims to improve trimming efficiency, ensure the smoothness and accuracy of trimming, and reduce the difficulty and risk of manual trimming. It is usually equipped with a powerful motor or engine to drive the blade or cutter to rotate at high speed to achieve rapid trimming of the green belt.

[0003] However, in practical applications, highway greening trimming devices also face some challenges. Due to the different widths of highway green belts, the adjustment structure of the device becomes cumbersome and time-consuming. This is mainly due to the fixed and inflexible design of existing devices and the complexity of the working environment.

[0004] First, many existing greenery trimming devices are relatively fixed in structure, which requires frequent manual adjustments when facing green belts of different widths. This adjustment process is not only time-consuming and labor-intensive, but may also affect the trimming effect due to improper operation. In addition, the environment of highway green belts is changeable and may include obstacles and uneven terrain, which further increases the difficulty and time-consuming nature of the adjustment.

[0005] Secondly, the lack of flexibility in the design also limits the application scope of greening trimming devices in highway green belts. Some devices may not be able to adapt to green belts of different widths, resulting in poor trimming results or failure to complete the trimming task. This not only affects the overall aesthetics of the highway, but may also pose a potential threat to driving safety.

[0006] Therefore, in order to overcome these challenges, future highway greening pruning devices need to pay more attention to design flexibility and adaptability, so as to better adapt to green belts of different widths and complex operating environments. At the same time, improving and adjusting mechanisms, simplifying the adjustment process, and improving pruning efficiency and quality are also important directions for future development.

[0007] The main purpose of the utility model is to provide a highway greening pruning device, which can effectively solve the problems raised in the background technology.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] A highway greening pruning device comprises a support frame, a transmission device, a side frame and a pruning rake, wherein the transmission device is mounted on the support frame, the pruning rake is mounted on the side end of the support frame through the side frame, and the pruning rake is designed to be perpendicular to the support frame;

[0010] An upper fixing frame is installed on the two side frames, and an oblique fixing frame is provided at the lower end of the upper fixing frame, and aligned sliding grooves are opened at the upper fixing frame and the oblique fixing frame, and the connecting screw is inserted into the sliding groove, and the connecting screw is fixed to the upper fixing frame and the oblique fixing frame by a fastening nut;

[0011] The lower end of the connecting screw is connected to a fixed block, and the side of the fixed block is installed with an angle adjustment frame, a driving motor is installed on the angle adjustment frame, and the output end of the driving motor is connected to a pruning disc, and the shrubs on the highway green belt are pruned by the pruning disc and the pruning rake.

[0012] As a preferred solution of the utility model, the side frame is fixed to the support frame by bolts, and the side frame is connected to the pruning rake by bolts, and the pruning rake is designed as a rack;

[0013] As a preferred solution of the utility model, the upper fixing frame is designed as an integral unit with the pruning rake, and the cross-sections of the upper fixing frame and the pruning rake strip are designed in an "L" shape, the oblique fixing frame is obliquely arranged on the upper fixing frame and the pruning rake strip, and is fixed by bolts, and a rubber strip is bonded to the connection between the oblique fixing frame, the upper fixing frame and the pruning rake;

[0014] As a preferred solution of the utility model, the two connecting screws are symmetrically installed on the upper end of the fixing block, and the connecting screws and the fixing block are fixed by fastening nuts;

[0015] As a preferred solution of the utility model, the angle adjustment frame is fixed to the fixed block by bolts, nuts and washers, and the angle adjustment frame is fixed to the drive motor by bolts to adjust the position of the drive motor and the trimming blade;

[0016] As a preferred solution of the utility model, a plurality of the slide grooves are evenly distributed on the upper fixed frame, and the distance between the two pruning blades is adjusted according to the width of the highway green belt by moving along the slide grooves through the connecting screw rods.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] In the present invention, the width of green belts in different highway sections may vary, and our pruning device can easily cope with green belts of various widths by flexibly adjusting the distance between the pruning blades. This design not only avoids replacing the entire device or the cumbersome adjustment process, but also greatly simplifies the workflow.

[0019] In addition, the design helps improve the precision and efficiency of pruning work. By precisely adjusting the distance between the pruning discs according to the actual width of the green belt, we ensure that the pruning work can be carried out evenly and consistently. At the same time, by optimizing the pruning angle and speed, we further improve the pruning efficiency, effectively shorten the working time and reduce labor costs.

[0020] What’s more, adjusting the distance between the pruning discs can also help reduce damage to the green belt. If the pruning device cannot adapt to the width of the green belt, it may cause some areas to be over-pruned or under-pruned, causing unnecessary damage to the green belt. By accurately adjusting the distance between the pruning discs, we can ensure a more even and precise pruning work, thus protecting the health and beauty of the green belt.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figure 1 - Figure 5 As shown, a highway greening pruning device comprises a support frame 1, a transmission device 2, a side frame 3 and a pruning rake 4. The transmission device 2 is firmly mounted on the support frame 1 to provide a power source for the entire device. The pruning rake 4 is cleverly mounted on the side end of the support frame 1 through the side frame 3 to ensure that the pruning rake 4 is designed vertically with the support frame 1 so as to better perform greening pruning work.

[0029] On the two side frames 3, a sophisticated upper fixing frame 5 is installed. This design not only increases the stability of the entire device, but also improves work efficiency. At the lower end of the upper fixing frame 5, an oblique fixing frame 6 is cleverly set. This design makes the device more stable and less likely to shake. Aligned sliding grooves 7 are provided at the upper fixing frame 5 and the oblique fixing frame 6, so that the connecting screw 8 can be smoothly inserted, and the connecting screw 8 is firmly fixed to the upper fixing frame 5 and the oblique fixing frame 6 by tightening the nut 9.

[0030] The lower end of the connecting screw 8 is connected to a sturdy fixing block 10. A flexible angle adjustment frame 11 is installed on the side of the fixing block 10. This design allows the device to adjust the pruning angle as needed. A powerful drive motor 13 is installed on the angle adjustment frame 11, and the output end of the drive motor 13 is connected to a sharp pruning disc 12. Through the coordinated work of the pruning disc 12 and the pruning rake 4, the shrubs on the highway green belt can be efficiently pruned.

[0031] The side frame 3 is tightly fixed to the support frame 1 by bolts to ensure the stability of the entire device. The side frame 3 is also connected to the pruning rake 4 by bolts, so that the pruning rake 4 can perform pruning work stably. The pruning rake 4 has a unique design and is in the shape of a rack, which can better adapt to shrubs of different shapes.

[0032] The upper fixing frame 5 and the pruning rake 4 are designed as one body, making the whole device more compact and beautiful. The cross section of the upper fixing frame 5 and the long strip of the pruning rake 4 is designed in an "L" shape, which not only increases the stability of the device, but also makes the whole device more durable. The oblique fixing frame 6 is obliquely arranged on the upper fixing frame 5 and the long strip of the pruning rake 4, and is fixed by bolts to ensure the stability of the whole device. Rubber strips are also bonded at the connection between the oblique fixing frame 6 and the upper fixing frame 5 and the pruning rake 4 to reduce friction and noise.

[0033] Two connecting screws 8 are symmetrically mounted on the upper end of the fixed block 10, making the entire device more balanced. The connecting screws 8 and the fixed block 10 are firmly fixed by the fastening nuts 9 to ensure the stability of the connection. The angle adjustment frame 11 is fixed to the fixed block 10 by bolts, nuts and washers, making the angle adjustment more flexible and convenient. At the same time, the angle adjustment frame 11 is also fixed to the drive motor 13 by bolts, so that the drive motor 13 and the trimming blade 12 can work stably.

[0034] In addition, a plurality of chute grooves 7 are evenly distributed on the upper fixing frame 5, so that the connecting screw 8 can move freely along the chute groove 7. By adjusting the position of the connecting screw 8 in the chute groove 7, the distance between the two pruning blades 12 can be flexibly adjusted according to the width of the highway green belt, thereby adapting to the pruning requirements of green belts of different widths.

[0035] Working process: Start the transmission device 2 to provide power for the entire pruning device. The transmission device 2 can be an electric motor or a hydraulic motor, etc., and its output end drives the pruning rake 4 and the pruning shear disc 12 to work through a transmission mechanism such as a chain or a gear; next, the operator adjusts the angle adjustment frame 11 according to actual needs to make the pruning shear disc 12 reach a suitable pruning angle. The design of the angle adjustment frame 11 makes the adjustment of the pruning angle flexible and convenient, and can meet the needs of pruning shrubs of different shapes and densities; then, start the drive motor 13 to drive the pruning shear disc 12 to rotate at high speed. The sharp blades of the pruning shear disc 12 can effectively cut the shrubs and complete the pruning work. At the same time, the rack shape design of the pruning rake 4 can better adapt to the shape of the shrubs and improve the pruning efficiency; during the pruning process, the operator can achieve precise pruning of the shrubs by controlling the speed and direction of the transmission device 2, as well as the rotation speed and angle of the pruning shear disc 12. At the same time, the stable design of the structural components such as the side frame 3, the upper fixing frame 5 and the oblique fixing frame 6 ensures the stability and safety of the entire device during the pruning process; finally, after completing the pruning of a section of the green belt, the operator can adjust the position of the connecting screw 8 in the slide 7 to adapt to the pruning requirements of green belts of different widths. This design enables the pruning device to flexibly respond to pruning tasks in different scenarios and improves work efficiency.
