Description

Jet flow type profiling follow-up root cutting device for grassland pasture recovery

Technical Field

Background

The prairie leymus chinensis is perennial rhizome grass, the rhizome of the prairie leymus chinensis is developed and mainly distributed in a soil layer of 5-15cm, and the prairie leymus chinensis has no rest for a long time, is over-loaded to be grazed and is trodden by livestock to be eaten, and the rhizome is comprehensively staggered along with the prolonging of the growth age limit, so that the hardening of grassland soil is serious, the air permeability is poor, the growth is weak, and the yield of the prairie leymus chinensis is reduced, therefore, when the prairie leymus chinensis is used for 5-6 years, the rhizome is usually cut by a leymus chinensis root cutting machine, so that the asexual propagation of the prairie chinensis is promoted, and the continuous high yield of the prairie leymus chinensis is kept. In the correlation technique, the ripple blade disc cuts the root, the break shovel loosens the soil, and ditching has caused very big disturbance to the grassland, and soil is very easily blown away by wind and causes the soil desertification, so needs land wheel suppression. The main defects at present are that natural grassland soil is hardened, the ditching resistance is large, stones in the grassland easily cause damage of soil contact parts to lose efficacy, and the power consumption of root cutting, soil loosening and pressing is large, so that the adaptability, reliability and economy of the root cutting fertilizer applicator are low, and the large-scale improvement benefit of the degraded grassland is limited. The water jet cutting is that high-pressure water passes through a specially designed nozzle small hole to form a high-energy jet beam with the speed several times of the speed of sound, the jet has huge kinetic energy, and when the jet beam acts on an object to be cut, the generated impact force reaches the material damage limit, the jet beam can cut or break. The existing jet flow type weeder mostly has the following problems: (1) the distance between the nozzle nozzles is fixed and cannot be adjusted, the growth distance of the leymus chinensis is not fixed, and the rhizomes of the leymus chinensis cannot be efficiently cut by adopting one distance, so that the working efficiency is reduced, and a large amount of time is wasted; (2) the distance between the nozzle and the ground is inconvenient to adjust, and the nozzle cannot adapt to grasslands with different densities and different flatness degrees.
