    摘要:

    在實驗室土槽中對旋耕—碎茬通用刀片單刀扭矩進行了試驗，確定了在旋耕作業(yè)和碎茬作業(yè)時，耕深、刀輥轉(zhuǎn)速、機組作業(yè)速度對功率消耗的影響，建立了這兩種作業(yè)狀態(tài)下扭矩與工作參數(shù)關(guān)系的回歸方程。土槽試驗結(jié)果表明，轉(zhuǎn)速對功率消耗影響顯著，耕深影響次之，作業(yè)速度對功率消耗影響較小。將通用刀片安裝到仿生智能耕整機上進行田間旋耕和碎茬試驗，田間測試結(jié)果表明，耕深穩(wěn)定性達93%，平均碎茬率、根茬覆蓋率、碎土率分別為81.8%、87.2%、87.9%，均滿足兩種作業(yè)的農(nóng)藝要求。

    Abstract:

    Power consumption (torque) tests of a single universal blade for rototilling and stubble breaking were conducted in the soil bin, to investigate the influences of the tillage depth and rotary speed of the blade as well as the working speed of the machine on power consumption. The regression equations for the relations between power consumption and the above parameters were established. Soil bin tests indicated that the parameter that had significant influence on power consumption is the rotary speed, next is the tillage depth, and the working speed had less influence. Then the universal blades were mounted on the bionic intelligent rototilling-stubble-breaking machine to perform rototilling and stubble-breaking tests respectively. Field tests showed that the stability of the tillage depth is over 93%, stubble-breaking rate, stubble coverage rate and soil-crushing rate are 81.8%, 87.2%, 87.9% on average, respectively, which meets the agrotechnical requirements.
