The substrate and seeds are placed on the seedling plate 15, and the servo motor 11 is started. The servo motor 11 drives the rotating frame 12 and the rotating shaft 16 to rotate, which in turn drives the fixed rod 13, the connecting frame 14 and the seedling plate 15 to rotate. The connecting frame 14 rotates around the fixed rod 13 under the action of gravity, and the seedling plate 15 always remains in a horizontal position, so that the seeds on the seedling plate 15 are evenly illuminated by the light source. The lubricating liquid is put into the oil storage tank 24 through the oil injection pipe 25, and the lubricating liquid is soaked into the sponge 23 through the oil leak. The screw 21 is turned, and the screw 21 drives the fixed plate 22 and the sponge 23 to move. The guide rod 2 The 6th step acts as a guide, moving the fixing plate 22 and sponge 23 to the appropriate position. When the fixing rod 13 rotates, it contacts the sponge 23, and lubricant is applied to the surface of the fixing rod 13 to lubricate the connection frame 14 and the fixing rod 13. The water inlet pipe 31 is connected to an external water pump, which pumps clean water or culture solution into the water distribution pipe 32 and sprays it out through the nozzle 33, spraying the clean water or culture solution onto the substrate on the top of the seedling board 15 to replenish water for the seeds or seedlings. The counterweight 4 is slidably connected to the bottom of the connection frame 14, increasing the weight of the bottom of the connection frame 14 and lowering the center of gravity of the connection frame 14 and the seedling board 15. The knob 5 is turned by hand, which drives the lead screw 21 to rotate. When the hand contacts the knob 5, the anti-slip texture 51 increases the friction between the knob 5 and the hand. Waste water dripping from the seedling board 15 is collected by the water collection tank 6, improving the convenience of waste water collection and reducing the situation of waste water dripping onto the ground and causing dirt.
