Description

Technical Field

[0001] The invention relates to the technical field of hedge trimming, in particular to a self-propelled hedge top and side branch and leaf synchronous trimmer. Background Art

[0002] Conventional hedge trimmers are green belt trimming equipment that rely on a small gasoline engine to drive the blade to cut and rotate. They are generally handheld or vehicle-mounted, with a single function, and are mostly used for trimming ordinary green belts. With the continuous development of social economy, large green belts such as highways have rapidly emerged, posing new challenges to trimming work.

[0003] Take the highway as an example: the middle of the two-way lane of the highway is a green belt. The main function of the belt is to separate the two-way vehicles, relieve the dizziness caused by the passing vehicles, and avoid the blinding of the headlights of the oncoming vehicles at night. Therefore, it can reduce the safety hazards of vehicle driving to a certain extent, and also play a role in beautifying the highway and protecting the environment.

[0004] At present, the vegetation on the slopes of highways mainly relies on manual pruning. Workers need to hold portable pruning equipment, but the length and width parameters, pruning flatness and even pruning efficiency are required to be high. Manual pruning is difficult and the pruning efficiency is low. Domestic vehicle-mounted hedge trimmers are generally in the form of vehicle-mounted single-arm structures. Although this product is more efficient than traditional manual pruning methods, it also has disadvantages such as single function and poor reliability. Because the moving vehicle has no lifting function and is affected by the uneven road surface, when using this type of hedge trimming machinery to complete the trimming of the top and sides of the central hedge belt, one trimming often fails to meet the requirements of flatness, and the vehicle needs to go back and forth for multiple trimmings, which has certain limitations.

[0005] Therefore, there is an urgent need to develop a hedge trimmer with efficient self-propelled top and side synchronous trimming of hedges, which can trim the top and side surfaces of the middle hedge at one time to improve the efficiency and benefits of the maintenance unit's work.
