1. The conveying arm is foldable and occupies little space. 2. The height of the output end can be adjusted to reduce the damage to the potato skin during loading 3. The loading efficiency is high. The entire lifting conveying device is divided into continuous U-shaped potato pockets by a 20cm plastic mesh fence at an equal distance. The potatoes are more stable, with a larger lifting angle and higher efficiency than the slope loader during the lifting process 4. Additional cleaning. High strength, perforated, elastic mesh conveying device is used to further clean the clay on the potato skin during the conveying process. 5. Good protection effect and durability. The two sides of the conveying device are sealed with elastic rubber fingers to prevent potatoes from leaving the conveying device. At the same time, they make the potato transport stable without friction. Rubber fingers are very flexible and can be used permanently at all deflection points with little wear.
