Abstract:

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.

摘要：

入土切割是降低甘蔗收获机破头率的重要方法。为了实现甘蔗收获机切割器随地面起伏自动调控入土深度，保持切割器入土深度的一致性，基于4GQ-1型甘蔗收获机，设计一种甘蔗收获机切割器入土切割深度监测与自动控制系统，实现切割器入土深度自动调控及其参数可视化，并通过室内试验和田间试验检验系统的监控性能。室内试验结果表明，监控系统的入土深度监测精度平均值为98.90%，自动控制精度平均值为97.7%，监测精度和自动控制精度达到95.0%以上。田间试验结果表明，在20、30和50 mm入土深度的条件下，监控系统的自动控制精度的平均值分别是85.3%、90.6%、94.1%，自动控制精度达到85.0%以上，监控系统总体设计合理，性能良好。研究结果可为甘蔗收获机切割器入土切割深度控制系统研究提供理论参考，对甘蔗收获机优化升级具有重要的参考意义。
