A plowing tool

Abstract

The invention discloses a subsoiling and tilling knife tool. The subsoiling and tilling knife tool comprises a knife carrier, a spiral sheet is fixed on the knife carrier, knife blades are mounted on the spiral sheet, a first soil piercing knife blade is fixed at the lower end of the spiral sheet, and a second soil piercing knife blade is fixed at the lower end of the knife carrier; and the lower ends of the first and second soil piercing knife blades are lower than the bottom face of the knife carrier, an inclination angle of the first soil piercing knife blade and an inclination angle of the second soil piercing knife blade each is slightly greater than a spiral angle of the spiral sheet, crushing and leveling knife blades are arranged at the upper end of the knife carrier in a staggered manner, and each crushing and leveling knife blade has an insertion part, a first bent part and a second bent part. According to the subsoiling and tilling knife tool, due to the structure, the subsoiling and tilling knife tool can more easily pierce soil and is more uniformly stressed during soil piercing, so that leveling re-crushing for topsoil can be better carried out by using the knife tool.

Description

technical field [0001] The invention relates to loose tillage cutters. Background technique [0002] For the loose tiller, one of the important parts that affect the loose tillage effect is the loose tiller tool. The traditional loose tillage tools are plow and harrow, but the plow can only plow the land and cannot achieve the purpose of crushing. Although the harrow can play a certain role in crushing, the crushing effect is poor and the crushing efficiency is low. [0003] With the country's strong support for agricultural production, the current semi-automated or automated farming equipment has been widely used, such as existing agricultural machinery such as seeders and harvesters. [0004] For plants, the fluffy soil can promote the root system of the plant to be more developed during the growth process, and the developed root system can absorb more nutrients from the soil, making the plant grow faster and more lush. When cultivating the land, if we continue to use tr...

However, the cross-cutting blade of this structure cannot effectively perform secondary crushing on the soil. In addition, if the pile of soil is too much or too high, the cross-cutting blade of this structure may be stuck due to insufficient power when leveling the soil. , and eventually the drill pipe will stop rotating, while the power continues to output, it is easy to damage the equipment or even burn the equipment
