In order to realize the accurate horizontal seeding of sugarcane seeds, a kind of pre-cutting sugarcane transplanter was designed. The influence that the speed of seed metering chain, angle of chain and angle of cane box made on the performance of planting was confirmed by analyzing the movement of the planting device and the simulation study. By using the sugarcane planter test platform, the physical experiments of the first-stage chain speed, the angle of conveyor chain inclination and the cane box inclination angle of planting device were carried out. The experiment results showed that the angle of chain had a very significant impact on the performance of planter. The speed of chain shaft and angle of box had no significant effect on the performance of planter. The order of primary and secondary factors affecting performance was the angle of conveyor chain, rotation speed of chain shaft, and inclination angle of cane box. There was no interaction between these factors. The optimal value of chain angle was 55°, the best value of chain shaft speed was 9.16r/min, the best inclination angle of cane box was 45°. In performance verification experiments, missing seed rate was 5%, replanting rate was 3.2% and pass rate was 92.6%. The reseed phenomenon during the planting can be effectively avoided. The seed consumption can be reduced during the planting process, and the missing seed phenomenon can also be avoided during the planting process. The qualified rate of seed metering direction was 93.37%, and the qualified rate of seed metering plant spacing was 90.33%. The spacing of planting was between 33cm and 49.5cm (a reasonable range), and the precise horizontal planting of double-buds section sugarcane can be realized.
