Problems solved by technology

However, the existing miniaturized soil scarifiers have some defects, which reduce the efficiency of soil scarification and the ease of use
First of all, in order to ensure the stability of the structure, the miniaturized soil loosening machine generally cannot be folded, so that it will occupy a large space when not in use and is not convenient for storage; in addition, the process of loosening soil will generate a lot of dust that is not easy to dissipate, which will affect the operator's body Health; third, due to the miniaturization of the ripper, when encountering a relatively hard soil block, it is easy to be tilted or even bounced by the vibration force, which is laborious and laborious

Abstract

The invention provides a foldable handrail. The handrail is divided into a lower pole body and an upper pole body. Connecting pieces are respectively fixed on one side of the lower pole body and the upper pole body. The connecting pieces of the lower pole body and the upper pole body The ends are respectively hinged to a rod shaft, and the upper rod body realizes rotation and folding relative to the lower rod body through the connecting piece and the rod shaft. The handrail of the invention can be folded and disassembled conveniently.

Description

technical field [0001] The invention belongs to the technical field of agricultural production machinery, and in particular relates to a small ripper. Background technique [0002] The soil scarifier is a commonly used machine for loosening hard soil, frozen soil, old soil surface and other cultivated land in the agricultural production process. After planting for a period of time, the soil tends to harden and agglomerate, which reduces the air permeability of the soil and affects the cellular respiration of the plant roots. The use of rippers to plow the soil particles can increase the gaps between the soil particles, strengthen the respiration and transpiration of the roots, and can also Promote root absorption and exchange of nutrients in the soil. [0003] Large-scale soil rippers are not suitable for the use of planting soil on slopes, small farmlands, and family gardens. Simple and compact rippers are flexible and convenient, and are widely used in these areas. Howev...
