Corn is one of the main food crop in north China, the planting area is broad, corn seedlingtransplanting technology is an effective way of cultivation of corn production, is an important partof the corn fertility techniques, is early sow, early maturity, an important means to escape summerdrought. The technology of the main features are: choose satisfactory, seedling, seedling fieldoperation process was finished ahead of schedule, such as, in turn, changed the traditional way ofcorn, greatly improve the corn planting area and yield. Application of this planting technology hasthe following advantages: The first is the resistance to low temperature, avoid early frost damageto seedlings. The second is effective to solve the contradiction in each quarter indirect stubble,stages of growth and yield increase. The third is to reduce cost of corn, significantly improve theeconomic benefit.Transplanting machine is a key link of the maize seedling transplanting technology, lowassurance rate artificial planted seedlings planted all degrees of difference and low survival rate ofdefects. Mechanical transplanting maize with high survival rate, high assurance rate, planting alldegree is high, planting depth uniformity is good wait for a characteristic, Most of the currentdomestic application of transplanting machine is semi-automatic transplanting machine, Is thecommon disadvantages of these types of planting machine are planting frequency is low, usuallyonly35~60plants/points, therefore, it is difficult to use large area promotion. The researchresults show that the factors influencing planting frequency is mainly influenced by artificialseedling rate, when the speed of the artificial seedlings above60plants/time-sharing, people willfeel panic, overworked, leading to lost the seedlings efficiency drops, prone to throw the seedlings,lost the seedlings phenomenon, the serious influence plant quality and how to improve thefrequency of semi-automatic feeding seedling transplanting machine become the most criticalproblem in transplanting machine was developed.In view of the current domestic semi-automatic transplanting machinery plant the problem oflow frequency and in combination with transplanting maize agronomic and efficiency requirement,this paper studies with automatically submitted to the office of seedling transplanting machine ofcorn, the transplanting machine can send the seedlings, furrowing, planting, covering and suppressmultiple operations, such as a one-time, its main characteristic is to use the machine to send theseedlings to replace artificial seedlings, from artificial plant seedlings into the one-time on whole set seedling, greatly reduced people’s labor intensity, solved by the seedlings of the decline of theefficiency of high speed cause. Not only improve the degree of mechanization of the wholeprocess of transplanting, and significantly improve the efficiency of the transplanting machine,eventually to reduce corn planting cost, increase production is critical.In this article, through analysis of the current way of transplanting machine at home andabroad to send seedlings, finally determine the transplanting machine adopts the mechanized sendseedling way, according to the features of dish itself has a small hole at the bottom, the studydesigned the top seedlings with device, remove seedlings from dish smoothly is realized. At thesame time the machine using the crank connecting rod mechanism, realize the device seedlingsand seedlings is harmonious and unified, through a large number of test finally determine thetransmission parameters of transplanting machine main institutions. In maize transplantingmachine of agronomy agronomic requirements under the premise of the original opener oftransplanting machine and the roller was improved. At the same time according to the variabilityof transplanting planting depth and speed of design parameter of automatic send seedlingsinstitutions multi-factor orthogonal test, determine the transplanting machine in3.5~4.5km/hspeed and planting depth for100~120mm operation case, it is best of planting quality.The transplanting machine has simple structure, novel design, low cost the most keycomponents designed adjustable structure, make it simple and flexible operation, easymaintenance, has the extremely broad market application prospect. With automatically submittedto the office of seedling transplanting machine of corn for the successful development oftransplanting machinery in our country from semi-automatic to fully automated development hasmade some very meaningful work.
