韭菜联合收获机的设计与试验OA

To resolve the problems of uneven stubble cutting,disordered harvesting and low efficiency of manual collec-tion and bundling in the current mechanized harvesting of Chinese chives,combined with the physical characteristics of Chinese chives and domestic Chinese chives planting agronomy,a Chinese chives combine harvester integrating the func-tions of feeding,cutting,clamping and conveying,orderly laying and collection and bundling is designed.The Chinese chives combine harvester adopts an electric self-propelled structure.The structural parameters of key working parts such as grain lifter,cutting device,clamping conveying and laying device,cluster and baling device are designed.The Chi-nese chives harvesting and baling test-bed is constructed,and the Chinese chives harvesting and baling tests are carried out.The test results show that the harvesting full stubble rate is 93.1%,the damage rate is 2.6%,and the loss rate is 1.8%.The harvester can complete the combined harvesting functions of Chinese chives full stubble harvesting,orderly conveying and cluster baling with low damage and high quality,and all performance parameters meet the design require-ments.
