[0039] The first gear ring is driven to rotate by the second motor, and the rotation of the first gear ring drives the driving component to slide on the bracket, thereby causing the boxes to move away from each other. During the movement of the boxes, the baffle originally slidably arranged in the first slide groove will be exposed, that is, the baffle is used to block the gap generated after the two adjacent boxes move, and the movement of the boxes will drive the baffle to move together, and the elastic cloth is used to block the gap between the baffle and the bottom plate after the boxes move, so that the box size can be adjusted, so that the plants have enough growth space; when the driving component drives the box to adjust the size, it will also drive the spiral conveying component to move upward for a short distance, and during the movement, the bottom plate and the box will vibrate slightly to achieve the function of loosening the soil; there is residual space after the box is adjusted in size, and the limit assembly can prevent the plants from collapsing.

Since the protrusions on the bottom plate and the first sleeve are engaged with each other at this time, the box, the bottom plate and the first sleeve will move upward together, and the second connecting rod will slide on the first connecting rod. At the same time, the first spring is stretched. After moving a certain distance, the combined force of the box, the bottom plate, the gravity of the soil and the tension of the first spring is greater than the maximum static friction between the protrusions on the bottom plate and the first sleeve.
