整秆式甘蔗联合收获机的输送通道总成的设计与试验OA

Aiming at the problems of existing whole-stalk sugarcane combine harvesters,such as unsatisfactory cutting effect,unsmooth feeding,easy blockage of the conveying channel,and low operational efficiency,a conveying channel assembly for whole-stalk sugarcane combine harvesters was designed.By analyzing key parameters including the structure and rotational speed of the conveying channel,the structures of various components(for sugarcane root cutting,feeding,conveying,leaf stripping,impurity separation,and sugarcane stem collection)and the matching of their operational parameters were optimized to improve the working performance and adaptability of the whole-stalk sugarcane combine harvester.Field test results showed that when the operating speed was 2.0 km/h,the cutter disc rotational speed was 600 r/min,the front conveying roller set was 280 r/min,the leaf stripping roller set was 1 100 r/min,the rear conveying roller set was 300 r/min,the leaf discharge roller set was 200 r/min,and the cane throwing roller set was 300 r/min,the trash content rate was 2.5%,the total loss rate was 2.6%,the broken stubble rate of ratoon sugarcane was 8.9%,and the qualified rate of sugarcane stems was 92.3%.The operating performance indicators of the harvester are superior to the technical requirements specified for whole-stalk sugarcane combine harvesters.
