Design and Experiment of Red Jujube Gathering Device Based on Bionic Mechanism
In view of the problems of the inability to gather the fallen red dates,the low efficiency of manual picking,and the low degree of mechanization in the southern Xinjiang region at present,based on the analysis of the jujube planting mode and the characteristics of the red dates materials,a rapid gathering device was designed by using the method of imi-tating the human arm to gather the red dates,and the structural parameters of each component were determined.The 3D modeling software SolidWorks and kinematics simulation software ADAMS were used to model and kinematics simulation of the gathering device,and it was concluded that the speed of contact of jujube during the gathering process was from small to large and then to small,there was no sharp mutation,and the damage to jujube was small,which met the design re-quirements.Taking the jujube aggregation rate as the response index,taking the forward speed,crank speed and drum speed as the influencing factors,the orthogonal combination test was designed,and the quadratic polynomial regression model of each factor on the aggregation rate index was established,and the influence law of each factor on the aggregation rate was analyzed.The main objective function method in the multiple response method was used to optimize its parame-ters,and the best parameters affecting the jujube aggregation rate were obtained:the forward speed was 0.37 m/s,the crank speed was 58r/min,and the drum speed was 32 r/min.At this time,the jujube aggregation rate was 88.65%.The research results can provide some reference for the improvement and development of the subsequent landing jujube gathering device.
