免耕半精量播种机的研制

摘要

文章阐述了一种免耕半精量播种机总体方案的确定和主要工作部件参数选择的原则及结构设计。该机解决了免耕播种过程中作物残茬对机具的缠绕和堵塞，避免了因壅土导致机具阻力过大、种肥混施、对土壤扰动过多等问题。该机结构简单、操作方便、制造成本低廉，而且一机多用，适宜在中小型农场或种植专业户中推广应用。%This paper described the determination of a general scheme on a kind of no-tillage half-precision seeder and parameter selection and the structural design of its main working parts. The machine solves the twining and jams by crop residue on the machine during the no-tillage sowing. That avoids the extreme resistance on the machine, mixture of the fertilizer and seeds,soil disturbance and other issues caused by earth hilling. This machine is simple in structure,convenient in operation and low costs in manufacture and it is a multi-purpose machine ,which is suitable for spreading and application in small and medium farms or specialized households.
