我厂在牵引五铧犁的基础上,改成了深耕犁,现已使用三年多了。改制的深耕犁可深耕50厘米(上翻27厘米,下松23厘米),班效达40亩,改制后不破坏原五铧犁结构,恢复原状仍能普耕。该犁存在的问题是耕作阻力大。改制的方法(见图):1.卸掉五铧犁的第四、五两犁体。为了减少阻力,在第二、三犁体的犁柱与梁架联接面处加垫板,使犁体向 I plant on the basis of the five-plow traction, into a deep plowing, has now been in use for more than three years. The plow system can be deep plowing 50 cm (up 27 cm, down 23 cm), class efficiency of 40 acres, after the restructuring does not undermine the original five-plow plow structure, restore the status quo can still farming. The problem with the plow is the heavy tillage resistance. The method of restructuring (see Figure): 1. Remove the fifth and fifth plow the fourth and fifth plow body. In order to reduce the resistance, in the second, three plow plow columns and beam joints at the surface of the pad, the plow to the body
