摘要
介绍了悬挂式棉秆粉碎还田搂膜机的设计要求、基本结构,给出了搂膜机构的结构参数。对切根铲工作阻力进行了理论分析,并通过试验获得主要技术参数;同时,搂膜齿排列试验结果表明,搂膜齿的排列方式对搂膜率有一定的影响,最后一排的齿密度越大效果越好,但排列过密容易壅土,齿间距最小约为110 mm;通过综合试验,确定了悬挂式棉秆粉碎还田搂膜机的主要技术参数的较优水平组合;切根铲工作深度H为4～5 cm、提升角(或碎土角)β为16°、机具前进速度V为6.2 km/h。
This article concisely introduced the design requirement and main components of hanging film raker with crushing cotton stalk and returning fragment to field, and presented the configuration parameters of raking film mechanism. Based on the theory analysis and the tests of working resistance of root cutting shovel, the authors gained the level of main technological parameters of root cutting shovel; the authors also studied on the arrangement of raking film tooth, the results indicated that the array of raking film tooth had a certain effect on film raking ratio, the larger array density of last row is, the better effect of raking film, but if array density was so denser that the tooth is clogged by the soil, and the minimum space between tooth is about 110 cm. At last, the authors attained the better level combination of main technological parameters by integrated experiment, which is that combination of the work depth cutting root shovel is about 4-5 cm, upgrade angle β（or smash soil angle） is 16° and machine working speed V is 6.2 km/h.
