The rotating screen guard plate 6 can provide an installation position for the components inside and drive the surrounding components to vibrate mechanically. A rotating screen 11 is installed on the inner side of the rotating screen guard plate 6. The rotating screen 11 can roll by the rotating screen drive motor 12, and then the fruit scooped up by the digging shovel 9 can be vibrated and screened, so as to shake off the soil on the surface of the fruit and transport and collect the fruit. A digging shovel 9 is installed on one side of the rotating screen guard plate 6. The digging shovel 9 can contact the ground, and then the fruit inside the soil can be scooped up and transported to The rotary screen 11 is used for transportation and soil removal. A rotary screen driving motor 12 is installed on the front side of the rotary screen guard plate 6. The rotary screen driving motor 12 can rotate after being energized, thereby driving the rotary screen 11 to roll. The output end of the rotary screen driving motor 12 extends to the interior of the rotary screen guard plate 6 and is connected to the rotary screen 11, which is used to transport the potato crops and vibrate the soil. The fruit is moved by the rotary screen 11, and mechanical vibration is performed under the cooperation of the vibrating arm 1 2 and the vibrating arm 2 5, which can shake off the soil on the surface of the fruit, facilitate the collection of the fruit, and avoid damage to the fruit.
