A weeding device for the between-seedlings in paddy field was designed,and its structure and working principle were gone into details.Carrying out the weeding experiment on the seventh day of transplanting rice seedlings,with the Box-Behnken experiment,the weeding-rate was affected by the numbers of gears,weeding depth,inclined angle for the test factors,and the experimental data was pressed and analyzed with the Design-expert software,and the best operating parameters were optimized.At last the best parameters of weeding device on the seventh day of transplanting rice seedling were 12 gears,42 mm of the weeding depth and 8°of the inclined angle,then the weeding rate was 68.7%.The weeding device between seedlings through the cultivator experiment provided a reliable weeding device for the design of the cultivator.
