Design And Experimental Study Of Collecting And Distributing Soil Device Of Self-propelled Potted Flower Automatic Transplanter

The method of collecting and distributing soil device is the most important part in potted flower transplanting technology.Pot soil filling is basically carried out manually for small and medium greenhouse potted flower transplanting in China,which is labor intensive and inefficient.Therefore,developing a self-propelled automatic transplanter for flower has been an urgent demand for the usage of small and medium sized,soft potted pots transplanter.This research summed up the development condition for flower transplanter based on the analysis for physical and mechanical properties of soft pot.And designed the self-propelled flower transplanter collecting and distributing soil device part based on the small and medium greenhouse properties.The main research results of this paper include the following aspects:(1)According to the actual working environment in greenhouse and the demands of users and the performance of the potted flower pot seedling automatic transplanter,the overall structure of the collecting and distributing soil device was determined.According to the design requirements,different design schemes of the collecting and distributing soil device for potted flower automatic transplanter were proposed.(2)Through the comparative analysis of the two schemes,the optimization of the design scheme was completed,and the overall structure of collecting and distributing soil device by 3D modeling software Solid Works.The mechanical system design of the potted plant automatic transplanting machine was completed by using the simulation analysis method.Physical and mechanical properties function for collecting soil device was built according to the actual operation situation,and it was analyzed from the microscopic and macroscopic aspects,and the important components of the collecting soil device were designed and calculated.At the same time,the static analysis of the collecting soil device frame and the allowable stress check of the material were carried out through Solid Works Simulation.Combined with the design requirements of the potted flower automatic transplanter,the design and calculation of the distributing soil device of the collecting soil device,the design and calculation of the conveyor belt size,and the static analysis and material permitting of the conveyor roller through Solid Works Simulation stress check.(3)Complete the design of control and drive system for the potted flower automatic transplanter collecting and distributing soil device.By analyzing the working logic of the this two devices and the operating parameters of each driving component during the operation,the motor required for the collecting soil device is selected,and the gear reducer is selected according to other conditions,and the motor and control components selection for distributing soil is completed.(4)Based on the theory and method of experimental analysis,taking the matrix mixed soil as the research object,the collecting and distributing soil device of the potted flower automatic transplanter were tested respectively.Firstly,the single factor experiment of the l colletingsoi device were selected as experimental factor,the error rate of the soil volume was selected as experimental index.Secondly,the single factor experiment of the soil distributing device is carried out,in which the opening angle of the soil controller,the running speed of the conveyor belt and the inclination angle of the soil separator were selected as experimental factors.The filling rate of the soil was selected as experimental index.The optimized parameters were selected through the triple quadratic regression orthogonal rotation combination test method.The collecting and distributing soil test results shows that the design can fulfill the requirements of the flower transplanter.
