Abstract: Aiming at the problems such as  the complexity of ground conditions after the Camellia oleifera tree forest, the limited space for the picking machinery operation, and the challenges of medium and large‑scale mechanized picking, a lightweight and simple Camellia oleifera fruit lateral branch clamping vibration picking device based on the working principle of horizontal clamping vibration picking of the Camellia oleifera lateral branches was designed. The mechanics model for Camellia oleifera fruit vibration was established by analyzing the main factors that affected the effectiveness of Camellia oleifera fruit picking, based on the vibration device picking principle and experimental analysis methods. The experiment tested the Camellia oleifera fruit picking rate and bract damage rate by using branch diameter, amplitude, and frequency of the vibration mechanism as test factors. The results showed that the vibration frequency of the vibration mechanism had the most significant impact on the Camellia oleifera fruit picking rate and bract damage rate. Specifically, when the branch diameter of 16 mm, amplitude of 40 mm, the vibration frequency of 16 Hz, corresponding to the Camellia oleifera fruit picking rate was 85.70%, bud damage rate of 4.45%, which was in line with the picking requirements.
