The Combination Of Tray Seedling Transplanting Into Pot Mechanism Design And Optimization

Flowers cultivation as an emergin g industry in modern agr iculture, esp ecially the cultivation of greenhouse flowers, is increasin g the degree of attention. In order to cater to the market demand, the industrialization of flower cultivation is d evelop in g continuously. However, the p roblem in automatic f lower mechanization p roduction common is the low efficiency and low success rate, if this p roblem can be solved smoothly in the p remise of quality assurance, the automatic p roduction mechanization develop ment of flower industry will be p romoted effectively.On the basis of extensive r esearch at home and abroad of transp lanting machin es and soil p rocessing agr icultural machines, for the f lower seedlin gs growth in 15 x 7 hole tray, p uts forward the combination of tray seedlin g transp lanting into p ot transp lanting machin e p roduction line scheme. The design p rocess is starting the combination of artificial hole tray seedlin gs transp lanting p rocess, comp lete the whole working p rocess of p lanning, and comp lete the structure design of p roduction line each p art, p rototyp e p roduction and exp eriment. On the basis of that, to soil build and cavitation stability as the op timization objective to study cavitation mechanism, comp lete the build and cavitation p rocess analy sis, and comp lete the build and cavitation mech anism design again, by exp erimental verif ication the soil build and cavitation effect. Research the soil build and cavitation sy stem of build and cavitation mechan ism, soil, flowerp ot by the modeling simulation and exp erimental an aly sis of cavitation mech anism, and bu ild up the multip le factors op erating system of cavitation mechan ism. On the basis of cavitation sy stem, research of the cav itation mechan ism optimization study against cavitation problems such as p oor stability, the soil collap se, through the analy sis of the organ ization op eration failure mechanism, and through the theory of TRIZ innovative methods to op timizing design of cavitation mechanism to achiev e the structure op timization design of the key mechanism. Then, carry out the p arameter optimization design and research, usin g Plackett-Burman design method to filter the p arameters, and through the orthogonal exp erimental method to get the effect maximu m value p arameters of the cavitation mod el sy stem, comp lete p arameter op timization design. The main research work and achievements are as follows.(1) Frist, based on the basis of consid erin g transp lanting object and the way of combination, start the combination of artificial hole tray seedlin gs transp lanting p rocess, comp lete the whole working p rocess of p lanning, the whole p roduction line accordin g to the functional modules are d ivided into p ot falling mechanism, soil fallin g mech anism, build and cav itation mechanism and p lug seedlin g comb ination transp lant mechanism four p arts. And then from the Angle of the mechanical d esign for each p art structure design research, accord in g to the module to comp lete the action required, determin e its working way and drive mode, and describ ed the p rocess of actual op eration, comp leted the combin ation of hole tray seedlin g transp lanting of the entire design into the basin.(2) Under the coordination of all modules institutions of transp lanting p roduction lines, p roduction of p hy sical p rototyp e and p rototyp e exp eriments, the exp erimental results show that the efficiency of p roduction line of transp lanting is far h igher than that of manual op eration, but also lacks in terms of success rate of transp lanting. Determined through the exp eriment analy sis and summary, the key of the success rate of transp lanting mech anism is built and cavitation mechan ism, and aims at build in g model cavitation failure p henomenon is analy zed, p ut forward a new bu ild and cavitation p rocess into a cave and built into a hole new p roject overall d esign, comp lete and the built model is verified by the exp erimental way cavitation effect.(3) Based on the new build and cavitation scheme, p rop ose the build and cavitation sy stem of build and cavitation mech anism, soil and flowerp ot, carry out the cavitation mechan ism of cavitation sy stem research. Combined with theory and exp eriment method, the sy stem of buildin g mod el cavitation effect and the f ailur e mechan ism of the cavity further through innovative methods TRIZ theory has been built and cavitation mechan ism k ey comp onents in the mold core and the new structure of the comp action module.(4) Carry out the structure op timization of build and cav itation mech anism b ased on the p arameter optimization design and study. Through the analy sis of the built model into a cave sy stem, get invo lved in all k inds of parameters in the sy stem, using the level 2 analy sis design method is used to filter the p arameters to get the p arameters of the strong correlation, h igh weight, and comp lete the p arameter test and test result analy sis, get the op timal p arameter combination.(5) After the comp letion of design imp rovements, comp lete the hole tray seedlin g fetching co mbination of transp lanting mech anism is designed, accord in g to its drag and combin ation p rocess, the reason in the form of a set of transp lanting to the p ot, the combination of flower seed lin gs and f ixed in the soil matrix cav ity within the basin, to comp lete the final work of transp lanting p rocess smoothly.The research achiev ements of this p ap er can p rovide for the combination of hole tray seedlings transp lanting op eration with high efficien cy, high success rate of automation equip ment. The study of the combination of tray seedling transp lanting into p ot transp lanting machine p roduction line has imp ortant p ractical value and high economic benefits.
