摘要:

为解决干旱地区现有保护型整地机功能单一、进地次数多、功率消耗大等问题，设计了一种深松、灭茬、碎土、镇压联合作业机。本文简述了整机结构和工作原理，并对深松、灭茬、碎土、镇压的作业装置进行了设计和理论计算，确定结构形式和参数。对镇压碎土辊与土壤接触过程建立模型并进行有限元仿真模拟分析，同时设计防夹装置解决粘附壅土现象。对整机稳定性进行理论分析得出该机符合雷诺1204机型悬挂质量要求。样机田间试验结果表明，该机深松深度为489.3?.6mm，深松稳定性为94.6%，根茬粉碎率为90.3%，碎土率为89.3%。该机各参数满足农艺要求，为联合整地作业机提供了参考。

Abstract:

Pointed to the problems of single function of existing protective tillage machine, many times enter the field and high power consumption, a subsoiling, stubbling, crushing and supressing soil combined tillage machine. The paper describes the structure and working principle, and the design and theoretical calculation of subsoiling, stubbling, crushing and supressing soil working device are carried out, then confirm the structural form and parameters. The model of the soil contact process of suppress soil crushing roller and soil is established, and finite element simulation analysis is carried out. At the same time, the design of anti clamping device to solve the adhesion phenomenon of hilling. The theoretical analysis on the stability of the whole machine show that it can meet the requirement of the suspension quality of the Renault 1204. Results of the field experiment show that the subsoiling depth of the machine is 489.3?.6mm, the stability of subsoiling is 94.6%, the crushing rate of root stubble is 90.3%, and the crushing soil rate is 89.3%. The machine parameters meet the agronomic requirements, which provides a reference for the combined tillage machine.
