用样机在重粘土及砂土中进行田间试验,以弄清深耕旋耕机的旋耕模型和刀轴扭矩的各种特性。本文主要对旋耕模型进行分析研究,深耕时,刀轴在地表以下向上切土的旋耕方式,在足够的转速下,切削的土块能良好地向后方抛掷,是一种有发展前途的深耕方法。第三报将叙述刀轴扭矩和比能量的特性。 Field trials were conducted in heavy clay and sand with a prototype to clarify various characteristics of the rotary model and shaft torque of the deep-plow rotary cultivator. In this paper, we mainly analyze and study the rotary tillage model. During deep tillage, rotary tillage with the cutter shaft cutting upwards above the surface of the earth can cut the soil well to the rear at a sufficient speed, which is a promising development Deep plowing method. The third newspaper will describe the spindle torque and specific energy characteristics.
