Subsoiling and tilling device

Abstract

The invention discloses a subsoiling and tilling device. The subsoiling and tilling device comprises a transmission case, wherein more than one transmission shaft is arranged in the transmission case, one end of each transmission shaft extends out of the transmission case, and extending ends of the transmission shafts are connected with 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, 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 device, due to the structure, the subsoiling and tilling knife tool can more easily pierce soil and is more uniformly stressed during soil piercing, and the fluffiness and crushing degrees of land in the vertical direction are different, so that the growth of plants is better facilitated, and 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 devices. 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 the given structure cannot effectively crush the soil for the second time. In addition, if the pile of soil is too much or too high, when the cross-cutting blade of the structure is leveling the soil, the horizontal cutting blade may be stuck due to insufficient power. , 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

[0007] In addition, during the growth of plants, the fluffy performance and degree of crushing in the vertical direction of the land will also affect the growth of plants.
