The Design and Study of the key Comppnents of 2BM-9 Model No-till Planter

主要论述了2BM—9型免耕播种机的构造及关键部件——开沟器与排种器的设计与参数的计算与确定,并且对播种机性能试验结果进行了分析,同时提出在研制中存在的问题及改进方法,本文可作为保护性耕作关键设备——免耕播种机设计的参考资料。

The design of construction and crucial components of the 2BM-9 model no-till planter as well as the calculation and determination of its relevant parameters were expounded. Besides, the testing result of performance of this machine was analysed, the problems existing in the developing course of its was pointed out and the corresponding ways for improvement was advanced in this paper. We deemed that this article can be used as a reference for the design of the no -till planter that is the key implement of the conservitive cultivation technique.
