During the fruit harvesting operation, the vehicle body 11 moves toward the fruit tree. When the vehicle body 11 passes the fruit tree, the harvesting ring 34 in a vibrating state contacts with the branches and leaves of the fruit tree. The harvesting ring 34 drives the branches and leaves to vibrate, so that the fruits on the branches and leaves fall off, thereby realizing the rapid collection of fruits. It should be noted that in order to increase the contact area between the harvesting ring 34 and the branches and leaves of the fruit tree, the harvesting ring 34 is tilted. Further, in this embodiment, the harvesting ring 34 is tilted toward the forward direction of the vehicle body 11; in addition, in this embodiment, the height of the vehicle body 11 should be greater than the height of the fruit tree, so that the fruit tree can pass through the vehicle body 11 smoothly;
