The invention provides a planting device. The planting device comprises a machine frame, a rotary driving device and a seedling picking and planting device, wherein the machine frame comprises two supporting plates which are arranged oppositely; the seedling picking and planting device is arranged between the two supporting plates and is hinged with the two supporting plates separately through a first hinged shaft; the seedling picking and planting device is used for picking and planting seedlings; and the first end of the rotary driving device is hinged with the machine frame, and the second end of the rotary driving device is hinged with the seedling picking and planting device to drive the seedling picking and planting device to rotate around the first hinged shaft to realize mutual switching between the picking position and the planting position. According to the planting device provided by the invention, the seedling picking and planting device is driven by the rotary driving device to rotate around the first hinged shaft and mutually switch between the picking position and the planting position, so that seedling picking and planting are realized, manual planting is replaced, the damage rate of the seedlings is reduced, the labor intensity is reduced, and the planting efficiency and the planting quality are improved.
