Parameters Optimization and Test of an Arc-Shaped Nail-Tooth Roller-Type Recovery Machine for Sowing Layer Residual Film

The aim of this paper is to optimize the working parameters arc-shaped nail-tooth roller-type recovery machine for sowing layer residual film. Firstly, tooth roller device film designed, and main affecting operation value range each parameter are determined through analysis process. Secondly, virtual simulation technology used establish a model interaction process between soil. At same time, taking soil-hilling quantity as index, we build quadratic regression mathematical with three factors—the forward speed, rotation depth—using Box–Behnken method. Consequently, results show that order most significant factors depth, speed. optimal combination follows: speed 4.5 km/h, 43.2 r/min, depth 100.0 mm. Meanwhile, predicted 23.1 kg. Finally, carried out field tests using parameters; normal collection rate 66.8%, 24.2 kg, relative error test 4.8%. This indicates devised DEM can be predict operational performance in study provides reference planning boundary enhancement agricultural machinery equipment.
