免耕播种机双刀盘有支撑切茬破茬装置的研制与试验

针对小麦收获后玉米免耕播种机作业时工作部件堵塞问题,该文提出了有支撑动力切茬和被动圆盘破土破茬联合作业的切茬方案,并设计了一种双刀盘动力切茬破茬装置,分析和确定了其主要结构参数。田间试验表明,双刀盘动力切茬破茬装置可将播种带地上部分96.2%的秸秆切断,地下的根茬98.7%破开,创造良好的种床条件,有效解决了秸秆堵塞问题,保证了玉米免耕播种机在小麦秸秆覆盖量较大时的通过性。研究结果为免耕播种机设计提供参考。...

According to the problem of straw blocking when using domestic no-till planters to sow corn in the fields with wheat straw-covered and residues, To overcome this problem,an attachment was developed to allow no-till planter to handle large amounts of straw and residue and improve planter performance. The device is consisted of a passive and a power driven coulter. The passive coulter is a ground-driven notched one. It penetrated into no-tillage soil and cut residue. The rotation direction of the power driven coulter is reversed. It cuts the covered straw on the soil surface together with the passive coulter. The key parameters were analyzed and determined. The field experiment showed that the device could cut off about 96.2% wheat straw on the seedbed
