盘刀式切碎器广泛地应用在青饲草收获机和青饲草切碎机上。设计常用图解法。用本文给出的数学解析法设计,可更合理地选择切碎器的几何参数,改善切碎器的工作性能。本文并以ZC-6型和9ZF-1.0型青饲草切碎机为例分析,给出了切碎器改进设计的具体方法,经计算可节省功耗12～33％。 Disc knife cleaners are widely used in green forage harvesters and forage shredders. Design commonly used graphic method. With the mathematical analysis method given in this article, the geometric parameters of the chopper can be more reasonable to improve the working performance of the chopper. In this paper, ZC-6 and 9ZF-1.0 forage grass shredder as an example analysis, given a specific way to improve the design chopper, calculated to save power by 12 to 33%.
