| By the end of 2014, the national apple area has reached 38.5 million acres, outp ut reached 39.58 million tons, apple production area in China accounted for 47.3% of the world,accounts for 40.8%. Apple industry is big industrie and farmers get rich. ap ple industry development in our country has entered a stable, peaceful development.Fertilization is an important link of the process of fruit tree planting, is one of the important measures for high yield and good quality fruit. At present domestic orchard fertilization by artificial fertilization, especially solid fertilizer is very deep trouble, need artificial digging ditches, fertilization, fill, not only time-consuming, laborious and bad for the fertilizer rate control, easy to cause waste, the intensity of labor is big, the efficiency is low,have do not conform to the requirements of modern fruit tree planting. Therefore, we need to solve the artificial low efficiency, big trenching fertilizer waste and low fertilizer effect.Based on the above factors, this topic is proposed to develop a set of furrowing, fertilizing,filling, leveling function in an orchard furrow fertilization machinery, trenching implement techniques namely uniform mixing、fertilizer、covering the joint operation, effectively avoid existing burn root phenomenon caused by the concentration of fertilizing, improve the work efficiency of orchard fertilization, promote orchard production stable and high yield of production, meet the needs of the development of current orchard industry, promote the rapid development of orchard planting industry.Design of fruit tree furrowing soil mixing fertilizer machine is mainly composed of frame,power transmission system, hydraulic lifting system, trenching work system, soil mixing system, covering plate, controlled distributing system, ground wheel. Tractor power after power transmission system of variable speed, through the chain transmission to drive the ditch assignments and soil mixing mixing operation of the stir over. Besides cutting out of the soil are soil collected from soil in the cylinder. Fertilizer box fertilizer fertilizer after the controlsystem of accurate control, by rows fat stir over to implement, soil, soil mixing barrel stirring.So as to realize the integration of furrowing, soil mixing, precise fertilization.Through consulting a large number of literature to compare trenching machinery research status at home and abroad, to provide theoretical basis for the design of fruit tree trenching machinery. UG 8.5 software is used to modeling and virtual assembly of the machine parts.By using simulation software simulation and analysis of key parts, the optimum designparameters,to ensure its reliability, and make the structure more reasonable. |
