| Abstract: | A comparison is made between tilling energy consumption characteristics of the moldboard plow and of the rotary blade and the approach pointed out to the reduction of the tilling energy consumption of the latter. By using a radiation spiral as a projection curve of the edge curve in the vertical view, differential equations are derived for the edge cuve, and its design parameters analyzed and dealt with. The designed widthwise edge curve will be used as a directix curve to form scoop surface of the energy-saving down-cut rotary blade by scanning method. |
