Description
Summary:Basecutting is a key procedure in sugarcane harvesting. It is necessary to improve the cutting quality of sugarcane for the development of mechanical harvesting. In the study, force analysis was conducted and demonstrated the stubble damage and uprooting mechanism, and it is found that the cutting force was not only related to the cutting length, but also related to the structural parameters (the cutting angle, the blade bevel angle, etc.) of the basecutter by mechanical equations. Then, field single-factor test was conducted to study the influence of the cutting depth (CD), the cutting angle (CA), and the blade bevel angle (BA) on the basecutting quality. The interaction of various factors and the optimal parameter was obtained by the response surface test. Through the response surface analysis and multi-objective parameter optimization, the influence of each factor on the evaluation index and optimal parameters combination was obtained. The order of three factors affecting the damage index (DI) and uprooting index (UI) was as follows: CA > CD > BA, and CD > CA > BA. It could get the optimal cutting quality when the CD of 10 cm, the CA of 10°, and the blade BA of 20°, respectively. After the field verification test, the stubble DI and UI index were −0.623 and −0.767, respectively, under the optimal parameter combination, which were in agreement with the predicted values of the model. The results could provide a reference for the structure improvement and performance optimization of sugarcane harvester.
