Portable scarifier

Abstract

The invention discloses a portable scarifier. The scarifier can reduce or eliminate the potential safety hazards caused by the beating of the machine body when breaking the soil. The portable scarifier comprises a machine body and a handle that are connected, the machine body is composed of a rotary knife assembly, a transmission module and a power module, the center line of the handle is perpendicular to the axis of the rotary knife assembly, a long rod-shaped plow aid for fixing the handle to the ground is pivotally connected to the handle,and the plow aid can maintain the angle between thehandle and the center line of the handle fixed in laying-down state or a retracted state. The portable scarifier also comprises a shock absorber clamped between the machine body and the handle and fixedly connected, the shock absorber can be deformed in the direction of the extension line of the center line of the handle and the direction perpendicular to the center line, and the shock absorber isa U-shaped leaf spring assembly with an upward opening.

Description

technical field [0001] The invention relates to a portable soil scarifier, which comprises a connected machine body and a handle. The machine body is composed of a rotary knife assembly, a transmission module and a power module. The center line of the handle is perpendicular to the axis of the rotary knife assembly. Background technique [0002] A scarifier, as the name suggests, is a practical tool for loosening soil. According to the size, it can be divided into large and medium-sized scarifiers and portable scarifiers. Large and medium-sized soil rippers are used as agricultural machinery in the field of agricultural production; while portable rippers are used in small areas such as home gardens, such as planting flowers and trees and fertilizing trees, etc., which require loose soil and soft land. Most of them are lawns or overgrown and hardened land, usually powered by electric motors or small gasoline engines; many operators are elderly people, women and other physica...

AI Technical Summary

Problems solved by technology

In the stage of breaking soil, the rotating loosening knife and the ground produce a large amount of continuous impact force, causing the body to generate intense jumping and impacting force. The violent jumping will bring safety hazards to the weak; stage, users often need to hold the handle of the scarifier tightly because of violent shaking when using it, which will cause an increase in user fatigue

[0004] Due to its portability requirements, the design of portable scarifiers has been blindly pursuing lightness, compactness and power, with little consideration for the safety and comfort of the operator.
