Optimal Design of Compensatory Cam for Precision Corn Planting Device of Furrow Seeder with Vertical Dropping with Whole Plastic-Film Mulching on Double Ridges

Abstract:

The design focus of precision corn planting device of furrow seeder with vertical dropping with whole plastic-film mulching on double ridges is to optimize its compensatory cam, and it aims to make compensation for the horizontal velocity of soil opener when the whole machine is moving forward. Under the precondition of ensuring sowing with vertical dropping by soil opener, the structure of compensatory cam shall also meet the requirements of smooth transition, space and cost saving. In order to achieve the above-mentioned design goals, the forward speed of machines and tools, the horizontal distance between the supporting point of amplification mechanism and the centering point of crank rotation, and the horizontal distance between cam and the centering point of crank rotation are taken as the experimental factors, offset circle radius, small-curvature radius and mass are regarded as the experimental indicators, therefore three factors and three levels orthogonal experiment is carried out, it is obtained that the optimal combination is A₁B₂C₁ by analyzing the results of experiment.
