Structure parameters optimization and performance experiment for planetary geared anti-sliding ground wheel

In order to solve the problem of seed missed caused by high sliding of no-tillage planter, a new planetary geared anti-sliding ground wheel was designed and its configuration parameters were optimized by experiments in this paper. The quadratic orthogonal rotational regressive tests were designed in the experiments with the ground wheel’s diameter, width, vertical load, extension of anti-sliding tooth as input parameters and sliding ratio as output parameters. The regression mathematics models between output parameters and input parameters were established and then parameters were optimized through Design-expert 7.1. The optimal combination was that diameter of the wheel was 626?mm, width of the wheel was 112 mm, vertical load was 214 kg, extension of the anti-sliding tooth was 28 mm, and the sliding was 0.45%in this condition. The verification test showed that advance speed of the implement was 6-8 km/h and the average sliding was 0.497%. The research provides a basis for technical support for designing no-tillage planter.
