Research and Validation of Vibratory Harvesting Device for Red Jujube Based on ADAMS and ANSYS

The mechanization of red jujube industry is a high-potential agricultural research field in China. In this study, vibration harvesting device has been developed for trees that features adjustable frequency and amplitude. designed to make vibrate with varying diameters by utilizing different frequencies amplitudes according the tree’s size such jujubes can be harvested efficiently. study completed structural design excitation fruit collection mechanisms based on working principle harvesting. mechanism was dynamically simulated using ADAMS, it found acceleration at end rod had tendency sharply increase decrease, which conducive shedding jujube. A collision model between umbrella constructed, structurally ANSYS. tests showed effectively from nine types diameter ranges 29.15–31.26 mm, 49.56–52.34 65.23–73.25 mm. average net rates were 93.98%, 94.71%, 94.33%, efficiencies 95.78%, 89.43%, 85.04%, respectively. These results demonstrate effectiveness provide theoretical basis development vibratory devices jujubes.
