摘    要:我国甘蔗种植主要集中在南方丘陵山区,地势起伏大,甘蔗收割机在收割过程中,刀盘不能随着地形变化自动调整高度,无法在合适的位置进行甘蔗切割,造成切割质量差及影响甘蔗第二年发苗和刀具损坏等问题.针对这一现象,设计了一种地面高度检测装置,能够测量出甘蔗垄的相对高度,并利用液压控制系统模拟甘蔗收割机的割台部分,配合检测装置进行了切割刀盘的仿地形自动升降测试.结果表明:地面高度检测装置的最大误差为6mm,采用了该检测装置的刀盘高度自动调节系统误差为9mm,能够满足生产使用的精度要求.

关 键 词:甘蔗收割机  高度检测  液压系统  自动调节

Abstract:In China, the planting of sugarcane is mainly concentrated in the hilly areas of the southern part of the country, where the terrain is undulating. In the process of harvesting sugarcane, the cutter can not automatically adjust its height with the changes of the terrain, so it can''t cut the sugarcane in the right position, causing poor cutting quality and influencing the germination of sugarcane the next year. In addition, the cutting tools may be damaged. In view of this phenomenon, a measuring device is designed, which can measure the height of the sugarcane ridges. The cutting part of the sugarcane harvester is simulated with a hydraulic control system, and an automatic adjusting test of terrain imitation is carried out. The result shows that the maximum error of the measuring device is 6 mm, and that of the automatic cutting height adjusting system with this device is 9 mm, which can meet the accuracy requirements of practical application.
Keywords:sugarcane harvester  height measuring  hydraulic system  automatic adjustment
