摘　　要：为了提高驱动圆盘犁的旱耕入土能力,改善平衡性能,该文提出了一种无需尾轮装置、由驱动圆盘犁和铧式犁组合而成的组合式左翻驱动圆盘犁,比普通驱动圆盘犁的结构有了显著的简化,减轻了犁的整机重量,降低了原材料及加工成本。通过对入土力矩及侧向力平衡装置在沟墙上的支撑面积的计算,结果表明了组合式驱动圆盘犁比通驱动圆盘犁入土力矩增大了58.8%,侧向力平衡能力增加2～4倍,可有效提高驱动圆盘犁的旱作耕深,满足一般旱作农艺要求。A solution was presented to increase the ability of embedment and improve the balance of power driven disc plow in dry-land. It synthesized left-turn power driven disc plow and moldboard plow. The new plow need no tail-wheel that much simplified the structure. As a result, the overall weight of the new plow was reduced, and the cost on material and manufacture was lowered. By calculating the embedment moment of plow and the support area of lateral-force balance device upon the plow groove, results showed that the embedment moment of the new plow was enlarged 58.8%, and the balance capacity was enhanced 2-4 times. Thus it increases the plowing depth and fulfills the demand of general agronomy in dry-land.
