1、摘要摘要: :大中型施肥播种机在小块地、 山坡地或套种作物行间进行播种时难以适应, 而传统人工播种的劳动强度较大,效率低,播种质量差,针对这种情况,应用人机 工程学的原理研究设计了一种手持式播种施肥机,该机也可在作物根部进行追 肥。主要由控制器、种肥箱、排种肥系统、鸭嘴式开沟器等零部件组成,适用于 谷物穴播或追肥,可使传统的人工播种(施肥)操作变为半机械化操作,将开沟、 播 种施肥、覆土一次完成。它采用了简单可靠的机构和通用的零部件,具有携带方 便、使用可靠,耗材少、易加工、成本低等特点。 关键词关键词:施肥播种机;开沟器;排种;施肥 Abstract : Working with large
