摘　　要：为推动玉米秸秆还田保护性耕作农艺的发展,设计了一种集土壤耕作技术、玉米秸秆还田技术于一体的1LF-5型液压翻转犁,一次作业既翻转了土层、松碎了土壤,又可将土壤表层的玉米秸秆与作物残茬翻入土层下,形成隔层进行还田;同时,犁体受到突发外力冲击时,安全装置自动生效,使犁柱绕固定轴栓旋转,从而保护犁体与犁柱的安全。田间试验表明:1LF-5型液压翻转犁的平均耕作深度稳定为33.45cm,平整度为20mm,变异系数在3.166%~3.535%之间;在第1工况下,翻转犁的耕宽平均值为220.75cm,耕宽的变异系数范围为1.21%~1.71%;在第2工况下,翻转犁的耕宽平均值170.1cm,耕作宽度的变异系数范围为1.26%~1.68%;植被覆盖率平均值为89.97%,土垡破碎率为72.27%。机具满足国家标准GB/T14225对于耕作质量的各项要求,也满足翻耕农艺要求。In order to promote the development of corn straw returning protective tillage agronomy,a 1LF-5 hydraulic flip plough integrating soil tillage technology and corn straw return technology is designed,which not only flipped the soil layer and loosened the soil at one time,but also flipped the corn straw and crop residue of the soil surface into the soil layer to form a partition layer for returning to the field,and at the same time,when the plough body was affected by sudden external force impact during the operation,its safety device automatically took effect,so that the plough column rotated around the fixed shaft bolt,thereby protecting the safety of the plough body and the plough column.Field experiments showed that the average tillage depth of the 1LF-5 hydraulic flip plough was stable at 33.45 cm,the flatness was 20 mm,the coefficient of variation was between 3.166%and 3.535%,the average tillage width of the flipped plough under the first working condition was 220.75cm,the coefficient of variation of the tillage width ranged from 1.21%to 1.71%,the tillage width of the flipped plough was 170.1 cm under the second working condition,and the coefficient of variation of the tillage width ranged from 1.26%to 1.68%.The average vegetation coverage rate is 89.97%,and the fracture rate of the soil is 72.27%,indicating that the machine meets the requirements of the national standard GB/T14225 for tillage quality and meets the requirements of ploughing agronomy.
