Arm type hedgerow trimmer

Abstract

The invention discloses an arm type hedgerow trimmer. The arm type hedgerow trimmer comprises a fixing plate, a supporting arm, a trimming saw head, a connecting seat and an adjusting hydraulic rod, wherein the supporting arm comprises a vertical arm, an angle adjusting arm, a telescopic outer arm and a movable arm; the lower end of the vertical arm is arranged on the fixing plate; the upper end of the vertical arm is hinged to the lower end of the angle adjusting arm; the upper end of the angle adjusting arm is hinged to one end of the telescopic outer arm; the other end of the telescopic outer arm is hinged to one end of the movable arm; the connecting seat is arranged at the other end of the movable arm; the trimming saw head is arranged on the connecting seat; the adjusting hydraulic rod comprises a lower hydraulic rod, an upper hydraulic rod and a top hydraulic rod; the lower hydraulic rod is arranged between the vertical arm and the angle adjusting arm; the upper hydraulic rod isarranged between the angle adjusting arm and the telescopic outer arm; and the top hydraulic rod is arranged between the telescopic outer arm and the movable arm. Trimming operation is facilitated, and the trimming quality and efficiency are greatly improved.

Description

technical field [0001] The invention relates to the technical field of hedge trimming, in particular to an arm-type hedge trimmer. Background technique [0002] Hedgerows are mostly green landscapes composed of dwarf shrubs, and are the main vegetation for adorning scenic spots, parks, residential areas, courtyards and urban greening. There are many species of trees that make up the hedge, and their growth characteristics are different. Some have trunks, some have no trunks, and the growth is different. Therefore, it must be pruned reasonably to become an ideal landscape. On the one hand, it is to control its height, and on the other hand, it is to form a certain shape, neat crown and side shape, etc. [0003] At present, the pruning geometry of hedge trees in China is mainly carried out by hand-held hedge trimmers or scissors, which has the following disadvantages: the hedge trimmer uses a single-cylinder gasoline engine as power, and its noise is high, which affects the w...

Problems solved by technology

[0003] At present, the pruning geometry of hedge trees in China is mainly carried out by hand-held hedge trimmers or scissors, which has the following disadvantages: the hedge trimmer uses a single-cylinder gasoline engine as power, and its noise is high, which affects the work and study of surrounding people; the labor intensity of green workers is high , the pruning work efficiency is low; and it affects the physical safety of greening workers; high energy consumption, serious pollution (gasoline engine combustion efficiency is low, releasing harmful gases); artificial pruning techniques are different, resulting in poor neatness and aesthetics
