【摘要】 针对现有秸秆粉碎旋耕播种复式作业机具,存在技术集成度不够、配套性差、作业效果不理想等实际问题,设计了一种新型秸秆还田施肥播种机;同时,阐述了该机的总体结构、设计原则以及技术参数,确定了播种施肥装置的结构与参数。通过应用实践表明,该机具有结构合理、紧凑等特点,适应范围广,能实现秸秆粉碎、旋耕整地、播种施肥、镇压一次性复式作业。更多还原

【Abstract】 There are many problems in the straw chopping rotary tillage seeding compound unit at present,such as bad technology integration,poor matching performance and non- ideal operating,etc. So a straw returning and fertilization seeder was designed in this paper. The overall structure,design principles and key technologies were introduced,and the structures and parameters of the seeding- fertilizing machinery were determined. Through the application in the field,it is showed that the teamwork machine has a reasonable and compact structure and wide applicability,which can realize straw chopping,rotary tillage,soil preparation,seeding,fertilization and compacting.更多还原
