To increase the qualified rate of sowing depth and the qualified rate of film hole for electric driving maize planter with dibbling on membrane, forward speed compensation device and limited depth mechanism were calculated. With Matlab impact of parameters of speed compensation mechanism on dibbling trajectory were simulated. Screening out that crank angular velocity, center distance and assistant crank length have significant impact on qualified rate of sowing depth and the qualified rate of film hole. According to response surface method with 3 factors and 3 levels, multi-factor variance analysis was conducted. Results showed that influence on the qualified rate of sowing depth was order, center distance, assistant crank length and crank angular velocity, and influence on qualified rate of film hole was order, assistant crank length, crank angular velocity and center distance. To get maximizing the qualified rate of sowing depth and the qualified rate of film hole, optimal parameters was that crank angular velocity was 89.10rad/s, center distance was 58.55mm, and assistant crank length was 95.1mm. Under that condition, the qualified rate of sowing depth and the qualified rate of film hole respectively was 94.89%, 93.61%. Test process showed that speed compensation mechanism run smoothly and reliably, and results met standard requirements related to seeder and agricultural requirements for maize planting in Gansu.
