Parametric Modeling and Moving Simulation of Vibrating Screen and Tubers on Potato Harvester

摘要

In order to overcome the behindhand and inefficient design of potato diggers, feature-based parametric modeling software Autodesk Inventor was used for modeling of potato diggers. The swing sieve, movement simulation with ADAMS was carried out. The complex velocity acceleration and displacement curves were analysed. Collision pressure curves were analysed too. Its velocity is less than or equal to 500 mm/s and its acceleration is more than or equal to 2.5 m/s~2 and less than or equal to 20 m/s~2. Test results indicated that Collision pressures of small and medium tubers are 120 Newton and 250 Newton, respectively, which are all smaller than damaging pressure. Potato can be transferred freely and damage rate is less than or equal to 4% when the frequency is 5.5 Hz and the swing is 30 mm.
