During the operation of the rice combine harvester, the fuselage tilts due to the tilt and unevenness of the ground affect its maneuverability and operational reliability. Aiming at the problem of leveling due to the tilt of the field surface, this research developed an innovative dual-parallelogram chassis lifting mechanism for rice harvesters designed a hydraulic system to adjust the chassis height by extending the cylinder. Using Adams simulation software, a detailed model of the lifting chassis was constructed to analyze its performance, revealing a direct correlation between the hydraulic cylinder extension and chassis elevation. Notably, the mechanism could achieve leveling on slopes with inclination angles of up to 7.5°. Comprehensive evaluations of the liftable chassis system were conducted under both static and dynamic conditions. In the static tests, the system exhibited the capacity for comprehensive or unilateral auto-leveling contingent upon the tilt, with leveling times and angular variations confined to 3.6 s and ±0.4°, respectively. In dynamic tests conducted on sloped fields and paddy soils, the system reduced post-leveling mean tilt angles and standard deviations remained below 1.2° and 0.6°, respectively. These results demonstrated a substantial improvement in the stability and reliability of the chassis during operations. This research provides valuable insights into the design and optimization of automatic leveling mechanisms and structural innovations for harvester chassis.

水稻联合收割机在作业过程中由于地面倾斜和不平整导致机身倾斜，影响其通过性和可靠性。本研究针对田间表面倾斜需要调平的问题，设计了一种适用于水稻联合收获机的双平行四边形底盘升降机构，并设计了液压系统，通过油缸伸出实现对底盘高度的调整。利用Adams软件构建了升降底盘的仿真模型，分析得出液压缸伸出长度与底盘高度呈正相关关系，且该机构能够在7.5°的倾斜角度下实现调平；并对可升降底盘系统进行了静态和动态评价。在静态试验中，系统能够根据倾斜情况实现全面或单侧自动调平，调平时间和角度偏差分别控制在3.6 s和±0.4°以内。在斜坡地和水田地上的动态测试显示，调平后的平均倾斜角度和标准差分别保持在1.2°和0.6°以下，显著提高了底盘的稳定性和可靠性。本研究为水稻联合收获机底盘的自动调平技术和结构设计提供了参考。

水稻联合收割机在作业过程中由于地面倾斜和不平整导致机身倾斜，影响其通过性和可靠性。本研究针对田间表面倾斜需要调平的问题，设计了一种适用于水稻联合收获机的双平行四边形底盘升降机构，并设计了液压系统，通过油缸伸出实现对底盘高度的调整。利用Adams软件构建了升降底盘的仿真模型，分析得出液压缸伸出长度与底盘高度呈正相关关系，且该机构能够在7.5°的倾斜角度下实现调平；并对可升降底盘系统进行了静态和动态评价。在静态试验中，系统能够根据倾斜情况实现全面或单侧自动调平，调平时间和角度偏差分别控制在3.6 s和±0.4°以内。在斜坡地和水田地上的动态测试显示，调平后的平均倾斜角度和标准差分别保持在1.2°和0.6°以下，显著提高了底盘的稳定性和可靠性。本研究为水稻联合收获机底盘的自动调平技术和结构设计提供了参考。

During the operation of the rice combine harvester, the fuselage tilts due to the tilt and unevenness of the ground affect its maneuverability and operational reliability. Aiming at the problem of leveling due to the tilt of the field surface, this research developed an innovative dual-parallelogram chassis lifting mechanism for rice harvesters designed a hydraulic system to adjust the chassis height by extending the cylinder. Using Adams simulation software, a detailed model of the lifting chassis was constructed to analyze its performance, revealing a direct correlation between the hydraulic cylinder extension and chassis elevation. Notably, the mechanism could achieve leveling on slopes with inclination angles of up to 7.5°. Comprehensive evaluations of the liftable chassis system were conducted under both static and dynamic conditions. In the static tests, the system exhibited the capacity for comprehensive or unilateral auto-leveling contingent upon the tilt, with leveling times and angular variations confined to 3.6 s and ±0.4°, respectively. In dynamic tests conducted on sloped fields and paddy soils, the system reduced post-leveling mean tilt angles and standard deviations remained below 1.2° and 0.6°, respectively. These results demonstrated a substantial improvement in the stability and reliability of the chassis during operations. This research provides valuable insights into the design and optimization of automatic leveling mechanisms and structural innovations for harvester chassis.
