Disc harrow blade device and harrow blade arrangement mode optimization method

The invention relates to a disc harrow blade device and a harrow blade arrangement mode optimization method; when harrow blades are arranged on a disc, a moving circular track of the telecentric endsof one stage of harrow blade in two adjacent stages of harrow blades coincides with a moving circular track of the proximal end of the other stage of harrow blade, and the moving circular tracks are concentric with an open circle in the center of the disc; compared with an equidistant arrangement mode of an existing disc harrow blade device, the harrow blade arrangement mode optimization method has the advantages that a harrow blade movement area can completely cover the disc, a large amount of materials are effectively prevented from being accumulated, the heat transfer area is effectively prevented from being wasted, the arrangement mode is suitable for various installation angles, and the process is simple and easy to understand; device performance can be significantly improved. 本发明涉及一种圆盘耙叶装置及耙叶排布方式优化方法，当耙叶在圆盘上
