Branch pruning machine for green belts

Abstract

The invention discloses a branch pruning machine for green belts, and belongs to the field of environmental construction management. The branch pruning machine comprises a carrying vehicle and a branch pruning device; the branch pruning device comprises a pruning mechanism, an adjusting mechanism and a branch recycling mechanism; the pruning mechanism comprises a main cutter wheel, auxiliary cutter wheels, a cutting motor, a transmission component and a protection cylinder cover, the main cutter wheel is directly driven by the cutting motor, the main cutter wheel externally engages with the auxiliary cutter wheels through gear teeth, and the inner wall of the protection cylinder cover is provided with rack rings which engage with the auxiliary cutter wheels; the interior of the main cutterwheel is provided with double layers of pruning blades, a front-layer pruning blade is directly connected with the output shaft of the cutting motor, and the free end of the front-layer pruning bladeis fixed on a wheel ring sleeve, a rear-layer pruning blade sleeves the output shaft of the cutting motor through a bearing, and rotating directions of the two layers of the pruning blades are opposite through transmission of the transmission component; and a filter net is arranged in a suction pipe. The branch pruning machine disclosed by the invention has a wider range of primary pruning, largepruning strength, more complete pruning and high pruning efficiency, facilitates saving energy, and has higher application value.

Description

technical field [0001] The invention relates to the field of environmental construction management, in particular to a green belt pruning machine. Background technique [0002] At present, pruning green belts is mainly to prune branches manually after leveling with ropes, holding scissors or hand-held electric tools. The pruned branches are scattered on the ground, and are first cleaned and piled to designated places by manual cleaning, and then centralized cleaning, especially highways. When pruning branches, there are many vehicles, which is easy to leave personal hidden dangers to the operator, and at the same time, it is labor-intensive and time-consuming. [0003] A hand-push hedge trimmer is disclosed in the patent with the authorization announcement number of CN 104488579 B, which includes a lifting device and a shearing device arranged on a trolley, and the lifting device and the shearing device are connected as a whole , It can be slid, rotated and lifted around th...

Problems solved by technology

However, it has the following disadvantages: the blade structure is simple, and during the cutting process, the blade rotates in one direction, and the building strength is small, and it is easy to produce branches that are missed, and the cutting effect on the branches is poor; , if the rear branch to be cut is bent due to the push of the front branch when it is cut, the blade cuts the rear branch without reset, which will result in only part of the branch to be cut or even not being trimmed. One-time cutting is not complete, which affects the cutting efficiency
