Improved Design Of 1-Row Trialed Potato Combine Harvester

With the market demand for potatoes continuously increased, it's industrialization and mechanization planting, harvesting, deep processing mechanism become an important subject in different countries. According to statistics, the world's potatoes planting area is about 20 million hm2in 2006, in which our countries planting area reached 5.0153 million hm2, with the potatoes planting area and the total yield all jumped to the first place in the world, our country become one of the quickest growing potato's consumer in the world. But in the most areas of our country, there are more than 70% total work of the potatoes harvesting are basically stopped in the traditional artificial seeding cutting, digging, picking stage, the level of mechanization of harvest in some areas relatively low, it's seriously influence the potatoes scale production and make it far not meet the demand of the market.In recent year, the research and extension of the potato harvest machinery has made a great development, but at present, our machine type mainly in small type, small mating power, simple structure and light. There is a big gap between our country and foreign country about the technology level of the equipment research, the labor intensity is still great, they are seriously hold back the potatoes industrial development. So in order to adaptation the globe and international competition, through the comprehensive research on the present potatoes harvest machinery at home and abroad, we improved the design of a new type single lined potato's combine harvest, which integrated the digging, separation, transportation, grading, cleaning and selecting, bagging(boxing) in one machine.After improved the design of the potato combine harvester, which separating device used the arc round roller components. This device has simple structure and good separation, overcome the restriction of the jitter chain and screen type separation, that in small type potatoes harvest machine and the use in viscous soil, improve the separation efficiency. The grading device's improve is mainly used the first order and the second order grading mechanism which composed of cylindrical roller and semi lunar groove had different space, realized the big, medium, small potatoes grading and transportation, greatly reduced the labor intensity and improved the product efficiency. After determined the whole improving design scheme, using the CAXA software built the integral three-dimensional modeling and make the motion simulation to the grading device by using the ADAMS software, analysis the all level potatoes simulated motion situation, verify the feasibility and reliability of the design and proposed the improving suggestion according to the simulation results.
