为了进一步完善耕作系统,针对国内外现有深松机存在的深松度达不到要求、耕作阻力大、易堵塞及能耗高等问题,对深松效应进行了深入研究,设计了适合在保护性耕作条件下进行深松作业的机械。通过对深松机工作原理和结构的分析与计算,确定了该机具各部件的总体布局,设计出适合动力配置的能对土壤进行高效松碎的深松部件及其结构参数。通过对深松铲作业时的受力情况进行详细地剖析,得出深松铲的结构参数工作幅宽B、翼宽b、翼张角a、刃角δ、翼倾角β、切土角i和隙角ε对其牵引阻力的影响。据此设计出新型凿尖加小双翼形深松铲。
In order to further improve the tillage system, in view of the problems of subsoiling degree, tilling resistance, blockage and high energy consumption of existing subsoilers at home and abroad, deep subsoiling effect was studied in depth, Deep tillage under the conditions of tillage machinery. Through the analysis and calculation of working principle and structure of the subsoiler, the overall layout of each component of the machine is determined, and the subsoiler components and their structural parameters that can be effectively and loosely shredded for the dynamic configuration are designed. Through the detailed analysis of the working conditions of the deep-shovel shovel, the working parameters of deep shovel shovel B, wing width b, wing opening angle a, cutting angle δ, wing inclination angle β, cutting angle i And clearance angle ε on the traction resistance. Accordingly, a new type of chiseling tip with a small wing-shaped deep shovel was designed.
