Design and Performance of Cutting Depth Monitoring System for Sugarcane Harvester Cutter
Cutting into soil is an important method to reduce the broken head rate of sugarcane harvester.In order to control the depth of the cutter automatically with the fluctuation of the ground and keep the consistency of the depth of the cutter,based on the 4GQ-1 sugarcane harvester,a monitoring and automatic control system for cutting depth of sugarcane harvester cutter was designed,which realizingautomatic control and parameter visualization of cutting depth,and the monitoring performance of the system was tested by indoor and field experiments.The indoor test results showed that the average monitoring precision of the monitoring system was 98.90%,the average of the automatic control precision was 97.7%,and the monitoring precision and the automatic control precision were over 95.0%.Under the condition of 20,30 and 50 mm depth in field experiment,the average of automatic control accuracy of the monitoring system was 85.3%,90.6%and 94.1%,respectively,and the automatic control accuracy was over 85.0%.The overall design of the monitoring system was reasonable,good performance.The results could be used as a theoretical basis for the research of cutting depth control system of sugarcane harvester,and had important reference significance for optimization and upgrading of sugarcane harvester.
