    摘要:

    針對河北省一年兩熟地區(qū)小麥免耕播種機存在的問題,提出利用驅動雙向螺旋刀作為向種行兩側推開秸稈和切斷種行上玉米根茬的開溝裝置,通過分析確定了雙向螺旋刀、弧形種肥開溝器的主要參數和雙向螺旋刀在刀軸上的排列方案。田間試驗表明,驅動雙向螺旋刀具有較強的向種行兩側推開秸稈的能力,能夠有效地切斷或切碎種行上的玉米根茬,安裝雙向螺旋刀與弧形種肥開溝器的小麥免耕播種機通過性能較好;施肥深度為8.56cm,播種深度為4.3cm;出苗情況表明作業(yè)質量能夠滿足小麥播種要求。

    Abstract:

    A dextral and laevogyrate helicoid driven cutting mechanism was developed for no-till drills in the area of two crops a year of Hebei province. In the operation of the no-tillage wheat drill, the mechanism worked well, moving the residue from the row, cutting off the corn stalk and rootstalk, loosening the soil of the seedbed and opening the seed furrows. The key parameters of the mechanism and an arc seeding-fertilizing opener were optimized and the optimal arrangement of the dextral and laevogyrate helicoid cutting mechanism was determined. In the field with cover of crop stubble, the anti-blocking performance of the new no-tillage wheat drill was well. The experimental result showed that it has a good ability to move the residue from the row and cut corn stalk and rootstalk. The depth of seeding fertilizer is 8.56cm and the seeding depth is 4.3cm. A good seedbed was made which is beneficial to seeds germinating and seedlings growing.
