Research Of Rotary-stubble Universal Blade Designing And Imitating Experiment

With science and technology development and agricultural mechanization increasing, and realize agricultural modernization, combining artificial intelligence and bionic mechanical technology theory, play an important role for applying to combine farming production, increasing production and saving energy.The rotary-stubble universal blade designing is studied in this paper. It is the critical component of bionic intelligent scarification equipment. In order to simultaneously satisfy plow, and broken spin crop two homework form, with high efficiency and energy saving, water conservation purpose realizing bionic mechanical technology applied in agriculture. Spin tillage-broken blade design crop general overall thought can be summarized as follows:First, the general blade equation of motion is obtained by analyzing the form of universal blade's movement and then the characteristic of the general blades curve equation is analyzed. Second, analysis of the structure of the general blade with general blade, get relevant design of structure parameters, choose the important structure parameters to arrange experiments.As with single-blade unit of general blade width torque is the indicator of power consumption and selecting the four important factors affecting general blade design gives nine groups. Each group general blade choose three levels, according to the mathematical statistical analysis of orthogonal table L9(34) sequenced the experiment table. According to the experiment in the laboratory respectively zero and watch broken stubbly spin homework test. Get the date of width torque with two assignments of rotary-stubble.Using the mathematical models of statistical analysis to respectively analyzing the date of width torque with two assignments forms test of rotary and stubble. Two assignments forms of experiment, the upper poor analysis the secondary order of four influencing factors, by comparing obtain optimal collocation program. Analysis of variance in the exclusion of a certain factors in the premise, analysis the influence of get three other factors even the width torque unit of significant differences. Finally, respectively get the regression equation of every factor and width torque in regression analysis, and then analyzes the curve of each regression equation, and obtain the change trend of reducing single-blade unit width torque, each factor value range change, eventually to guide the design of general blade.
