The water pump is turned on, and the external water source is conveyed to the hose 11 through the connecting pipe, and then enters the rotary water supply pipe 9 through the conveying pipe 10, and then enters the plurality of spray branch pipes 12 respectively, and is sprayed out through the plurality of atomizing nozzles 13 to water the seedlings; after watering the seedlings through the spraying mechanism 3, the motor 7 is turned on, and the motor 7 drives the rotary water supply pipe 9 and the rotating shaft 8 to rotate, driving the plurality of spray pipelines to rotate clockwise by 90°, and the plurality of spray pipelines are arranged upward; it creates favorable conditions for the efficient progress of photosynthesis of the seedlings during the seedling raising process, thereby promoting the vigorous growth and healthy development of the seedlings; in addition, when transplanting the seedlings, it makes it more convenient to take out the seedlings from the seedling tray body 1 and reduces the complexity of the operation;

[0029] When taking out the seedlings at a certain growth stage from the seedling raising tank 14 for out-planting, rotate the turntable 25. The turntable 25 drives the rotating shaft 24 to rotate. While the second bevel gear 23 rotates, it drives the first bevel gear 22 to rotate, and then drives the threaded rod 21 to rotate. Through the threaded fit between the internal thread sleeve 20 and the threaded rod 21, the lifting plate 19 is driven to rise. The slider 28 slides in the chute 27 at the same time, synchronously driving a plurality of struts 18 connected to the lifting plate 19 to rise. Two struts 18 located in the seedling raising tank 14 rise, and the two struts 18 synchronously drive the ejector plate 16 to rise. The ejector plate 16 gradually ejects the seedlings and the soil from the seedling raising tank 14 together. When the seedlings and the soil are exposed two-thirds of the height of the seedling raising tank 14, stop rotating the turntable 25, and take out the soil and the seedlings in a plurality of seedling raising tanks 14 in sequence; thus, the device realizes the function of efficiently and conveniently taking out the soil and the seedlings from a plurality of seedling raising tanks 14 at the same time, shortens the transfer time from the seedling raising tank 14 to the out-planting land during the transplanting process, and improves the efficiency of quickly taking out the seedlings from the seedling raising tank 14.
