Design and simulation of integrated machine for breaking film and covering soil on ridge

In order to solve problems of insufficient soil cover on root of tobacco seedlings and grasses grow easily around seedlings in Tongren tobacco-producing area by punching holes and transplanting seedlings after film, an integrated machine for breaking film and soil covering on ridging was designed for tobacco production in Tongren tobacco-producing area．The machine consisted of extended range generator, lead-acid battery, walking device, taking and moving soil device, breaking film and covering soil device, control panel, frame and driver's seat．The virtual prototype model of double-crank multi-link duck-bill breaking film and covering soil mechanism was established by Solidworks software．The model was simplified and imported into ADAMS for simulation analysis, and motion trajectory, displacement and time change curves in X and Y directions were obtained．Results showed that designed double-crank multi-link duck-bill breaking film and covering soil mechanism could meet requirements of 55 cm fixed plant distance breaking film and 0.067 hm²/h operation efficiency, which verified rationality of structure selection and parameter design．The machine could replace operation of artificial film covering soil, reduce labor and cost, improve efficiency of soil covering, and had value of popularization and use．
