Description

Technical Field

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

[0002] Urban greening is the activity of planting plants to improve the urban environment. Urban greening is the restorative tissue in the urban ecosystem. The urban ecosystem has the ability to recover from external interference and destruction, which is usually called the restorative function of the urban ecosystem. The main reason for the restorative function of the urban ecosystem is the role of the greening ecological environment in the city. The study of the urban greening ecological environment is to make full use of the urban greening ecological environment to make the urban ecosystem have a restorative function, which can improve the quality of the living environment of urban residents and also affect the reputation of a city. Usually, shrubs are trimmed manually using scissors or some other hand-held tools, which is time-consuming and labor-intensive. Therefore, a shrub trimming device for greening projects is needed.

If the length is not enough, the driving box is pushed to continue to extend by starting the hydraulic cylinder, and then the driving box drives the pruning shear disc to prune the shrubs, thereby improving the utilization efficiency of the pruning device. When pruning shrubs for greening projects, the pruning shear disc is driven by the driving box to prune the shrubs, and the two sides of the shrubs for greening projects will also grow excess parts, which also need to be pruned, but the device can only prune the top shrubs, which results in the device being unable to prune the shrubs on both sides, which has limitations, and then leads to low utilization efficiency of the pruning device.

[0026] Specific working principle:

[0027] When it is necessary to trim the shrubs, the first motor 11 installed in the supporting working groove 10 is started, and the first motor 11 drives the pulley 13, the belt 14 and the connecting column 12 to rotate. The rotation of the pulley 13 drives the first screw rod 15 to rotate and cooperates with the first guide rod 17. Since the first screw rod 15 is threadedly connected to the movable plate 20, the movable plate 20 is driven to rise, thereby realizing height adjustment. Then, by starting the second motor 21, the second screw rod 23 is driven to rotate, so that the threaded block 24 moves horizontally on the surface, and cooperates with the second guide rod 25 to push the movable block 2 to move horizontally. Then, the pruning shear disc 9 is driven by the drive box 8 to trim the top shrubs. When it is necessary to trim both sides of the shrubs, the worm 5 is driven to rotate by rotating the rotating handle 6, and the rotation of the worm 5 drives the worm wheel 4 to rotate. The rotation of the worm wheel 4 drives the rotating shaft 3 and the connecting rod 7 to rotate.
