Design and Virtual Test of Vibration-Type Digging Shovel
In order to improve the crushing soil effect of potato harvester, a vibration-type digging shovel with the amplitude and frequency adjustable was designed. The kinematic analysis of this vibration digging shovel was performed. A virtual prototyping model was established based on Solid Works and ADAMS software, and mechanical-hydraulic co-simulation was conducted in ADAMS. The virtual test results showed that: the amplitude of digging shovel was directly proportional to the system pressure; at constant system pressure, amplitude was inversely proportional to frequency; the maximum pressure value of the shovel on soil mass was lower than the breaking strength of potatoes.
