Study On The Handhold Grafting Machine

The machinery grafts is the contemporary one kind of emerging technology at this century.The main purpose is in order to reduce the worker labor intensity and increase the grafts quality.The grafts technology serves a contemporary agriculture better. The machinery grafts technology isfine accurate technologies and so on agriculture, micro electron, computer and automatic controlthe application centralism manifests in the agriculture, it is the agricultural production processautomation, the intellectualized important symbol. RealThe fruits and vegetables machinery grafts technology are the contemporary agriculture fruitsand vegetables production important link, it might enhances labor productivity and the work quality,reduces the labor intensity, improves working conditions, realizes fruits and vegetables growsseedlings the mechanization, the automation, the intellectualization. The grafting machines with thebiology characteristic and the cultivation way of the fruits and vegetables is obtain the developmentto mack grow seedlings. At present, Japan and South K orea should pass through the developmentand the commercialization production manual, semiautomatic and the completely automatic graftthe machinery. It mainly uses in the melon branch and the solanaceae fruits and vegetables.First, we according to the watermelon's biological characteristic, the cultivation way, grafts thecraft and the handhold graft machine the synthesis design synthesis principle, choice the way levelpeg grafting by the handhold grafting machine grafts. According to the measure of the grafsseeldings' biological structure characteristic and the technological requirement of grafts I design thehandhold grafting machine the basic organization.The clamps organization machine have clampsthe hinge by the double opening which braces with the flexible moderate double-acting. The stepmotor with the model fly servo and the static straight line step motor uses to provide the power forthe handhold grafting machine.With the multi-rigid dynamics knowledge, I estab[ishe the initial condition, the fundamentalequation and the Jacobian matrix for solution of the dynamics analysis model of the handhold graftmachine clamps organization and.After the determination handhold grafting machine organization, I use contemporarylarge-scale CAX software Pro/Engineer by the top to down design idea to design basic structure,and in the simple movement simulation and the interference inspection revises the handholdgrafting machine the concrete structure. And we carry on dynamics simulation with thecontemporary prototype software MSC.ADAMS and Pro/Engineer jointly, before physicalprototype test simultaneously obtains the reference in the design.We put this handhold grafting machine through a preliminary test with the twice develop software platform of AVR MPU control system What I compiler program for. It maybe bringscertainly conveniently for the control senate principle prototype parameter from the dynamicssimulation.After the mechatrical handhold grafts the machining to development completed, I carry on thedebugging to the prototype and test, and make the overall performance to the prototype tomake thecorresponding appraisal.This reseach studied in the process to apply the 3D modeling technology with top to downdesign idea, the modern rigid dynamics analysis, the modern simulation technology andmicro-electronic control technology and so on; we independently developed the handhold graftmachine, and solved the table graft machine the quality to bring the mobilized difficult problem;And unified the attempt with the theoretical analysis and the experimental study to carry on thesimulation analysis of the mechatrical handhold graft machine. The research result all have the vitalsignificance for the graft machinery miniaturization, the simplification, the collection assimilatedinto society.
