2JB非机动单行播种机的研究设计

对于大中型播种机难以作业的小地块的播种，以往均采用人工作业。人工播种劳动强度大、播种质量差，因而需要研制适合于小地块的非机动单行播种机。为此，论述了该机具的工作原理和结构特点；阐明了非机动播种机关键部件的设计思想；指出了该机具有的使用范围和市场前景。

Study and Design of 2JB Non-moter Single-row Drill

For small area infield which large and middle machine is difficult to drilin,manuawork is adopted usually. Manual work drilling is high toilsome, low-level drilling quality so it is necessary to design a mon-motersingte-row drill which is suitable for working in small area in field. This paper discusses the drills working principle and struclture,illustrates the design idea of pivoltal parts, points out the usage range and the market foregrand.
