農業機械.多功能通用機架和耘鋤,帶支撐的鴨式鋤鏟Aiming at the defects of the imc - 70 model stubble - plastic film residue collector that the draft is rather great and the plastic residue or stubble are sometimes left out in the operation process, formulas for the principal parameters of the knives have been driven out based on the analysis of the distribution manner in the field of the stubble and plastic film residue, the variation range and the variation tendency of the principal parameters for the reduction of the draft have been found on a trial basis in the corn field through theoretical analysis and experimental study and a mathematical model for the draft applied on the knives has been established in accordance with the movement and distortion of the soil under the action of the knives
本文針對1mc ? 70型地膜回收起茬機起膜、起茬鏟刀在作業中阻力大,殘膜、根茬有漏起的現象,通過對作物收獲后殘膜、根茬在田間分佈情況的分析,推導出鏟刀滿足生產要求主要參數的求取方法和公式,並經理論分析和試驗研究,確定了鏟刀對玉米茬地進行起膜、起茬時主要參數的取值范圍和減小牽引阻力各參數的取值規律。以鏟刀作用下土壤的運動變形為基礎,建立了鏟刀牽引阻力模型。Spade is the type of farm machine operator. many moulding - making method were tested in the research. common bi - spade, plain bi - spade and half - sweeps shovel ? solid mouldings were built
以鏟式部件為農機工作部件的代表,嘗試了各種鏟式部件的造型方法,建立了雙翼平鏟、雙翼通用鏟、單翼平鏟的實體模型。And the field of scientific research have been attached importance to research of subsoiling and develop of subsoiler, and gained considerable development, but subsoiling technology has not been extensive application, subsoiler has so many limitations too, and great resistance is prominent limitation. this dissertiation start with improving the status of resistance, optimizing parameter of structure, ploting structure graph of subsoiler by autocad, and constituting mathematical model of subsoiler resistance, finding out every affect factor of resistance, it is not only significant to optimize subsoiler, but to gain more precise value and parameter. and that it can detract the process of producing sample, experimentation and correcting, in addition to economizing time, saving resource and enhancing efficiency
本文從改善深松鏟受力狀況、優化其結構參數以更好的滿足深松要求入手,利用計算機輔助設計( autocad )技術繪制深松鏟的結構圖形以利於其分析和設計,並通過對現存深松鏟的結構和受力分析,建立了深松鏟工作狀態的受力數學模型,找出了影響深松鏟受力的各個因素,不僅對深松鏟的優化有著重大的意義,而且可以得到更加精確的數值和參數,並減少了必須生產出樣機進行試驗、修正等煩瑣的過程,大大節省了時間,節約了資源,提高了生產效率。分享友人
