Description

Technical Field

[0001] The utility model relates to the technical field of urban green belt trimmers, in particular to an urban green belt trimmer. Background Art

[0002] At present, seedlings in green belts of urban roads in China need to be pruned regularly. There are two main existing pruning methods: manual pruning and manual handheld chain saw pruning. Both pruning methods have the problem of low efficiency, and the pruning width can only be judged by the naked eye, which is difficult to control continuously and stably.

[0003] In order to solve the problem that the pruning width of the existing urban green belt pruning device is mainly judged by the naked eyes of the operator and the pruning width is not well controlled, the scheme CN210226296U discloses an urban green belt seedling pruning device, including a base, a branch and leaf collection vehicle body, a pruning saw and a branch and leaf collection box body, a pulley support rod is arranged on one side wall of the base, a supporting pulley is arranged on the pulley support rod, and a rotating shaft is arranged between the supporting pulley and the pulley support rod...

[0004] The above scheme sets a pulley support rod and a support pulley, so that when the push device is used to prune the seedlings in the green belt, the support pulley always rolls on the curb below the seedlings, thereby ensuring that the pruning width of the pruning saw is always consistent. However, it does not take into account that in practice, when the operator is pruning along the green belt, it is likely that due to the conscious attention of the electric saw pruning or the influence of the traffic next to it, it is difficult for the eyes to always keep an eye on whether the support pulley is against the curb, resulting in the push being unknowingly deviated, and the pruning of the pruning saw is also deviated. Therefore, it is difficult to keep the pruning width consistent from beginning to end only by subjective eyesight. Utility Model Content
