Hedge knife and hedge trimmer for spherical vegetation trimming

Abstract

The invention provides a hedge knife for spherical vegetation trimming. The knife comprises a bottom plate, two side plates, a lower serrated blade, an upper serrated blade, a movable plate and a rotating shaft, an opening slot is formed between the side plates and the bottom plate, and both ends of the movable plate are located in the opening slot; the hedge knife is characterized in that the lower serrated blade is fixed on the outer side of the bottom plate, and the upper serrated blade is located above the lower serrated blade and fixed to the movable plate; two ends, extending from the opening slot, of the movable plate are fixed to vertical guiding plates, guiding grooves are formed in the centers of the guiding plates, the two ends of the rotating shaft are arranged on the two sideplates, cranks are fixed at both ends, extending out from the side plates, of the rotating shaft, and the cranks extend into the guiding grooves of the guiding plates; the rotating shaft between the two side plates is fixed to two pulleys. According to the hedge knife, in the process of a belt driving the pulleys and the rotating shaft to rotate, the cranks at both ends of the rotating shaft can drive the movable plate to move back and forth, thereby driving the upper serrated blade to move back and forth relative to the lower serrated blade, and achieving the trimming work on plants.

Description

technical field [0001] The invention relates to a hedge knife and a hedge trimmer, more specifically, to a hedge knife and a hedge trimmer for pruning spherical vegetation. Background technique [0002] The hedge trimmer can trim green plants in gardens and greening roads. The hedge trimmer replaces the pruning pliers and relies entirely on manual trimming. It is driven by a motor or a gasoline engine, and the trimming of plants can be achieved by manually holding the hedge trimmer. With the requirements of garden design for changing plant shapes, the conventional flat shape no longer meets the requirements, and more and more plants require spherical shapes, such as holly balls, boxwood balls, etc. If the spherical shape of the purely artificial pruning plant is used, not only the work efficiency is low, but also the labor intensity is high. When the plant is relatively tall, it is necessary to use a climbing tool, which increases the difficulty and danger of pruning. [00...

Problems solved by technology

The drive shaft of the hedge cutter disclosed in the patent document CN2017108464243 is vertically arranged, which is not conducive to the arrangement of the belt, especially when multiple hedge cutters form an arc-shaped pruning knife, the belt is more difficult to arrange, which will affect the entire belt. Normal use of pruning knife
