垄作免耕播种机三维建模研究

Ridge tillage and conservation tillage combination is an important technology, the main role of northeast Alpine arid area development of ridge tillage and conservation tillage is to resist drought and wind erosion control, gradually fertility, while the sowing time can use mechanical removal of ridge and furrow can be covered with weeds, weed suppression using straw growth, reduce dependence herbicide. According to the characteristics of planting technology and conservation tillage technology, 3D modeling of ridge-till and no-till planter is Researched, including the planter frame, grass cutting disc, a furrow opener, a fertilizer box, pressing wheel and reshaped device etc.. The machine can finish the fertilization, seeding, soil covering, suppression and so on, and reduce the number of times of the machine. Three modeling of planter is useful to conducive to the promotion of no tillage seeding technique, and is a better combination of advantages of ridge tillage and conservation tillage.
