Design And Test Of 2ZZ-3 Deep Scarification Terrace Ridge Fertilzation Combine Intertill Machine

Deep loosening ridging fertilizer is an important production link in the process of planting corn.It can break the plow and further deepen the cultivation layer,it also can improve the soil layer structure and the ability of drought resistance and water.Corn root cannot grow without moisture nourishment,Cultivator can provide sufficient moisture of corn root growth.So that water can be supplied to the plant,and promote the growth of the plant.The crops need plenty of fertilizer in the growth process,fertilizer becomes particularly important,so deep loosening ridging fertilizer has important significance for agricultural development.This topic comes from the public sector(Agriculture)special scientific research(201503116-09):"Research and demonstration on the establishment of reasonable plough layer in the central and southern plains of Northeast China".The main research results and conclusions are as follows:(1)Through the analysis of the present situation of cultivating machines at home and abroad,introduces the advantages and shortcomings of the cultivator development,in order to solve the problem of soil tillage and soil fertilizing technique is not perfect,according to the special soil serious cause plant production at the same time in order to solve the problem,the area of Liaoning province in the construction reasonable technical index of related machines,developed a deep loosening ridging fertilizer combined cultivator.The structural design and material selection of each component is completed,and the three-dimensional modeling of the deep loose ridge,the depth limiting component and the fertilizer component.(2)On the basis of the overall structure design of 2ZZ-3 deep loosening ridging and fertilizing combine,the deep loosening ridging parts for the mechanical analysis,the paper researches the principle of forming Hiller surface,analyzes the process of turning over the soil covering device,the Hiller principle method.(3)Application of deep loosening ridging shovel handle model establishment of ANSYS Workbench software,and the finite element analysis was carried out,the equivalent shovel handle the stress and displacement plot,determine the deep loosening ridging shovel handle the maximum stress is 62.622 MPa,meet the design requirements.For monoblock hiller and surface hiller simulation,it is concluded that surface hiller ridging effect than a straightforward hiller ridging effect is better.(4)Based on soil moisture content and soil hardness determination on the test by the method of orthogonal experiment of three factors and three levels of 2ZZ-3 deep loosening ridging and fertilizing combine the effect of field work.To determine the speed of the tractor,subsoiling depth and Hiller open angle as three factors,specific resistance and seedling injury rate as test indexes.The results show that the speed of 5 km/h,subsoiling depth is 25 cm,Hiller open angle is 60 degrees.The seedling injury rate is the lowest,the minimum resistance ratio.
