摘　　要：To solve the problems faced by 4TSQ-2 sugar beet top cutting machine,i.e.large structure,high power consumption and high manufacturing cost,the multi-roller mechanism for leaves removal and fixed-thickness cutting method was studied.Using five-factor and two-level tests,the structure configuration of the leaf removal device was optimized,and the scheme of two roller shafts defoliation,the roller shaft rotation speed of 800 r/min and the forward speed of 0.8 m/s were determined.Through the working process and mechanical analysis of the top cutting device,the cutting device with the slant profiling plate structure characterized by a profiling angle of 25°-45°for the profiling plate and a cutting angle of 20°-40°was studied.With the two-factor and three-level experiments,the profiling angle of profiling plate of the top cutting device was 35°,and the cutting angle was 30°.Compared with the 4TSQ-2 sugar beet top cutting machine before optimization,the structure size of the machine was reduced by 30%,the weight was reduced by 15%,the cost was reduced by 25%,the qualified rate of top cutting wad was increased by 2.6%,and the push over rate of sugar beet was reduced by 0.5%.Besides,each index met the index requirements of beet top cutting harvest.
