2BF-8小麦精量播种机的开发与研究

Development and study on 2BF-8 wheat precision planter

小麦精量播种农艺可实现省种、增产,经济效益显著。要推广小麦精播技术,小麦精播机具是实现的手段和保障。结合国家自然科学基金课题,研制开发了一种小麦精量播种机具,该机以排种定量、准确、可控、无带动层的内充种垂直轮式排种器和张角可调分置双圆盘式开沟器等新型核心部件构成整机。经试验,其性能指标符合农业部颁布的“精量半精量机械化播种技术实施要点的规范。为此,对该机具主要零部件及参数确定进行了分析。

Some new important components such as seedermeter of inner-filling seed of the vertical wheel characterized by accuracy and controllableness as well no pulling layer and opener of double individual plates with adjustable field angle were designed with the planter. The results of the experiment showed that performance accord with the implementation indexes of precision and semi-precision seeding with mechanization that the Agricultural Department had issued. The design of new seedermeter and opener and study of whole planter including the mechanism of deep applying fertilizer were presented and analyzed in the paper.
