Design And Research Of Tea Micro Tillage Machine

Tea processing of intelligent clean to improve the quality of tea plays an important role,and the tea carding process is a key steps.In order to solve the conventional processing machine temperature control accuracy,large vibration,low the rolled twig rate and other issues,in reference to the article and foreign literature and existing processing machine,based on the combined requirements,designed a high temperature control accuracy,small vibration and high rolled twig rate of tea carding machine.The specific research contents are as follows:According to characteristics of tea carding process,determines the design of tea carding machine,analyzing the tea carding machine for belt transmission,the belt drive and two belt drive belt type,root number and speed of axial force;Using Matlab software calculation and analyzing the curve of tea carding machine by u type trough,combined with the least squares method to fit the curve that u type trough,results show that equation y=0.0005x~3-0.0211x~2+0.0946x-84.9003.Through carding machine kinematics and dynamics analysis,find trough and connecting rod the speed formula and acceleration formula,and the inertial force formula;using the series formula simplified inertial force formula,drawing in the formula with Matlab for graphics,to demonstrate the usefulness of simplified formula.On the basis of the inertia force analysis of carding machine U type trough and a connecting rod,and then through the crank on increasing weight method to reduce the inertia force,the quality of the final weight is 15kg,the horizontal displacement of tea carding machine vibration reduces 0.54mm,the vertical displacement reduced 0.40mm.In order to improve the rolled twig rate and reduce the broken rate,the transmission mechanism of carding machine and maximum of the minimum transmission angle as the design object,combined with the tea carding process requires,establishment of carding machine constraint equations,with the Matlab software optimization module,the genetic algorithm results showed that:the minimum transmission of the angle from 50°to71.1°,U groove working stroke by optimization of 118mm to122 mm;the limit angle decreased from 15°before optimization to 3.6°,carding machine work noise is reduced by 2 dB,the rolled twig rate increased by 2%.In order to change the traditional tae carding machine of the temperature accuracy,using the fuzzy algorithm to control the temperature of tea carding machine,using the fuzzy logic toolbox in Matlab and simulation tool Simulink,the establishment of tea carding machine temperature fuzzy control system model.Results showed that fuzzy temperature control on the main and auxiliary heating component with high stability,small overshoot and strong anti-interference ability,provide a reference for tea machinery intelligent processing.Tea carding temperature,tea carding time and leaf weight as experiment factors,single factor experiments were carried out in the experiment under the premise to become rolled twig rate and evaluation scores as the evaluation index,get into rolled twig rate and evaluation score influence is the tea carding temperature,followed by the teacarding time,after the leaf weight.The data processing method using multiple regression analysis,the establishment multiple regression equation,combined with Matlab artificial neural network optimization program,results show that the optimal tea carding process parameters temperature,tea carding time and leaf weight of 93?,5min and 1.0kg.
