【摘要】：針對現(xiàn)有開溝刀片在密植果園開溝施肥過程中存在功率消耗大、溝深穩(wěn)定性差的問題,運用旋耕理論和試驗分析的方法,設計了一種正弦指數(shù)曲線型開溝刀片。通過分析拖拉機前進速度、刀盤轉速以及二者相互作用對功率消耗和溝深穩(wěn)定性的影響,確定了正弦指數(shù)曲線型開溝刀片工作參數(shù)的最佳組合為:拖拉機前進速度1 m/s,刀盤轉速為200 r/min。以正弦指數(shù)曲線型開溝刀片B處彎曲角、彎曲半徑、C處彎曲角為影響因子,以功率消耗和溝深穩(wěn)定性為響應值,通過三因素四水平正交試驗,確定了正弦指數(shù)曲線型開溝刀片結構參數(shù)的最佳組合為:B處彎曲角為95°,C處彎曲角為140°,彎曲半徑為9 mm。對正弦指數(shù)曲線型開溝刀片和現(xiàn)有開溝刀片進行對比試驗,結果表明:在工作參數(shù)和開溝深度相同的條件下,正弦指數(shù)曲線型開溝刀片比現(xiàn)有開溝刀片功率消耗下降3.29 k W,溝深穩(wěn)定性提高8.83個百分點,各項技術指標均達到了國家相關標準的技術要求。
[Abstract]:In order to solve the problems of large power consumption and poor stability of ditch depth in the process of furrow application in close planting orchard, a sinusoidal exponential curve groove cutting blade was designed by means of rotary tillage theory and experimental analysis method. By analyzing the effects of tractor speed, cutter speed and interaction between them on power consumption and channel depth stability, The optimum combination of operating parameters of sinusoidal exponential curve open groove inserts is determined as follows: the speed of the tractor is 1 m / s and the speed of the cutter head is 200 r / min. Taking sinusoidal exponent curve cutting blade with bending angle at B, bending radius, bending angle at C as the influencing factor, power consumption and channel depth stability as response value, three factors and four levels orthogonal test were carried out. The optimum combination of structural parameters of sinusoidal exponential curve groove cutting blade is determined as follows: the bending angle at B is 95 擄, the bending angle at C is 140 擄, and the bending radius is 9 mm.. The comparison test between sinusoidal exponential curve groove cutting blade and existing trench blade shows that: under the same operating parameters and trench depth, The power consumption of sinusoidal index curve groove cutting blade is reduced by 3.29 kW and the stability of trench depth is increased by 8.83 percentage points. All the technical indexes meet the technical requirements of relevant national standards.
