摘　　要：多功能节水覆膜播种机是集起垄、开沟、施肥、播种、覆土、喷药、铺膜、压膜及膜上覆土等过程于一体的播种机。为此,通过对排种器、开沟器、挂膜机构、覆土镇压等装置的结构进行优化设计,解决了传统播种机功能单一及覆土筒盖土不实、种肥间距难以调节等问题。同时,利用Pro/E对播种机整机进行建模,对部分零件进行了参数化及动态仿真。结果表明:该机结构紧凑、功能完善,能够完成开沟、播种、铺膜、覆土、铺滴灌管,以及喷药等一体化联合作业。Multifunctional water-saving membrane seeder is one of the seeding machines which is used for seeding peanut and ditching ditches, ridging, fertilizing, seeding, covering soil, spraying and mulching.Based on the seeding device the design has solved some problems which the cylindrical sealers can＇t transport enough soil and the distance between seed and fertilizers is difficult to be adjusted, with structures such as opener, film device and cylindrical sealers have been optimized.Using PROE to make a seeder model, with some parts parameterized.Then make a dynamic simulation for the seeder.The results show that, the machine has a compact structure, perfect function, which can complete the ditching, seeding, mulching film, covering soil, drip irrigation pipe laying, spraying and other integrated joint operation.
