摘要：
针对中国南方稻田留茬高、土壤黏重,油菜栽种复式作业机耕整地作业部件易缠草、壅泥,影响作业质量和油菜出苗的难题,提出了将田间稻秸秆收集切碎并绕过耕作部件后均匀覆盖于播种行行间的种植方法,研发了多功能油菜覆草直播播种机,围绕该机器设计了一种动刀与定刀及风送叶片同轴安装的稻秸秆切碎装置,并分别对稻秸秆的＂站秆＂和＂残茬＂进行切碎台架试验。结果表明：喂入压辊转速、动刀转轴转速、动定刀间隙3个影响因素对切碎长度合格率、功耗影响显著;对＂站秆＂和＂残茬＂切碎的各因素取值为：喂入压辊转速399.2、401.64 r/min,动刀转轴转速968.12、977.23 r/min,动定刀间隙0.52、0.49 mm时,稻秸秆切碎合格长度率为95.78%、96.98%,功率损耗为3.09、2.68 k W。经整机田间试验,该装置的秸秆田间覆盖效果达到油菜种植农艺要求。该研究为多功能油菜覆草直播播种机产业化提供了技术参考。
