摘要
贵州烟区烟草种植多采用人工方式覆膜,作业成本高、劳动强度大、机械化水平低。为解决这一问题,根据贵州烟草种植农机农艺融合要求,研制了一款小型电动覆膜机,并简述了覆膜机的结构和工作原理。覆膜机采用主动培土方式实现覆土,分析了培土刀刀轴轴线与水平面夹角对覆膜质量的影响;通过EDEM软件对培土刀的入土过程进行仿真分析,确定了培土机构的结构和工作参数。田间试验结果表明,当覆膜机培土刀刀轴轴线与水平面夹角为5°时,覆膜后垄基宽、垄顶宽、垄高、覆土宽度、透光面宽度的稳定性系数均大于80%,断条率小于5%。
Cultivation of tobacco in Guizhou tobacco growing area mostly uses manual mulch covering,which is characterized by high operating cost,high labor intensity and low mechanization level.In order to solve this problem,a small motor drive mulching applicator was developed according to the integration of agricultural machinery and agronomy for tobacco cultivation in Guizhou.The structure and working principle of the mulching applicator were briefly described.It adopts active soil covering mechanism to complete the soil cover operation.The paper analyzes the influence of the angle between the axis of the soil tillage knife and the horizontal plane on the mulch covering quality.Through the simulation analysis of the soil tilling process by the tillage knife with the EDEM software,the structure and working parameters of the soil covering mechanism are determined.The field test results showed that when the angle between the axis of the blade and the horizontal plane was 5°,the stability coefficients of the width of the ridge base,the width of the ridge top,the height of the ridge,the width of the soil covering,and the width of the transparent surface after mulching were all greater than 80%,and the broken strip rate was less than 5%.
