Electric green fence shearing machine with speed changing structure

Abstract

The present invention discloses an electric cropper for hedgerow with a shift mechanism. The cropper includes a casing with an inner cavity. A gear ground plate ,a gear motion plate and a guiding orientating plate cooperate and are mounted on front end of the inner cavity, motor assembly consisted of a mini motor and a controller is installed outside of the casing, bevel wheel fabricated on exserting part of a center shaft of the motor extends into a inner cavity on rear end of the casing to mesh with a bevel wheel in the cavity of the casing; the bevel wheel is mounted on a gear shaft, the first end of the gear shaft is connect to a inside track of first bearing, a outside track of the first bearing is fixed on a casing of the mini motor; the second end of the gear shaft is connect to a inside track of the second bearing, a outside track of second bearing is fixed on outside cavity body of a upper cover. A turnplate is connect to the gear shaft, compliance mechanism of a connecting rod for controlling forth and back in reciprocating motion of the gear motion plate is mounted on eccentricity distance D of the turnplate surface. D is 5mm-30mm.Its structure is compact. It is easy to operate and carry, noise is low, whole assembled structure is reasonable.

Description

technical field [0001] The invention relates to a portable garden machine, in particular to an electric hedge trimmer with a variable speed structure.
