Improvement And Experimental Research On The Opener Of The Cultivator

As is known to all of the fertility in soil tillage increases with time and gradually decline, leading to crop yield and quality. To maintain and improve soil fertility, people must constantly applying fertilizer on the soil. Traditional fertilization mechanical opener fertilization depth more shallow, easy to cause chemical fertilizer volatilization and loss, waste of fertility, environmental pollution and destruction of ecological balance, the utilization rate of fertilizer directly affect the production.Aiming at the existence of heilongjiang province existing row mechanical fertilization depth, high injury rate, locomotive fuel consumption increase, in addition to the summary is not ideal, through the analysis and the research status of fertilizer machinery at home and abroad, to improve the key components of fertilization devices, using spherical single disc harrow piece to replace the traditional double disc type and cross knife type opener, and the fertilizer application prototype test, through contrast test optimization scheme was finally determined.Combined with the actual production situation of single factor experiment, the selection factors affecting the effects of fertilizing row homework for speed, rake Angle, fertilization depth, and the level of various factors were determined. On the basis of single factor to carry on the three factors five levels quadratic orthogonal rotation regression test. Of the use of software Design expert6.0.1 split groove parameters optimization, set up 3 d response surface figure of the various factors and two-dimensional contour map, and theoretical analysis of the test factors, get the opener work best when the locomotive speed is 7.5 km/h, harrow piece of Angle is 16.5 °, fertilization depth 8 cm, and a field validation test was carried out.Through the field test shows that the improved opener device can meet the requirements of agronomy, fertilizing row machinery in row and autumn ridging fertilizer to improve the fertilization effect, reduce consumption, reduce the injury rate, increase in addition to the summary, the increase of root density, the purpose of increasing production, for the research of the whole machine design provides an important theoretical basis.
