Aiming at the problems of poor cotton stalk pulling effect and poor quality of direct compression after pulling, the paper designs a cotton stalk pulling and crushing integrated harvesting platform for self‑propelled cotton stalk combine harvest baler, which can complete the functions of pulling, crushing and conveying at one time. Cotton stalks can be removed from the field using cotton stalk pulling mechanism equipped with soil loosening blades and pulling cotton stalk tooth plate, which can improve the pulling rate and reduce the breakage rate of cotton stalk. By coordinating the operation of the cotton stalk pulling mechanism and the crushing mechanism, the pulled cotton stalks can be crushed, which can improve the quality of subsequent bundling operations. The results of field comparative test showed that when forward speed of the machine, burying depth of cotton stalk pulling mechanism, rotation speed of cotton stalk pulling mechanism, rotation speed of crushing mechanism, rotation speed of conveying roller, and compression frequency of cotton stalk were 1.2 m/s, 0.1 m, 135 r/min, 1 800 r/min, 350 r/min and 110 times/min, the pulling rate, the breakage rate, baling density, baling rate, falling resistance rate and regular cotton baling rate of the machine were 98.4%, 1.31%, 159.28 kg/m3, 98.5%, 99.48% and 99.78%. The performance indicators of each test were improved by 4.79%, -63.61%, 8.83%, 2.48%, 3.73% and 1.51% respectively compared with the cotton stalk non parallel pulling platform, which indicated significant improvement in the operational performance of the cotton stalk pulling and crushing integrated harvesting platform designed in the paper.
