[0026] The present application provides a seedling tray watering device for automated rice seedling raising equipment, comprising a mounting frame 2 detachably connected to a conveying mechanism 1 of the seedling raising equipment, a passage for the seedling raising tray 7 to enter and exit is reserved between the mounting frame 2 and the conveying mechanism 1 of the seedling raising equipment, a limiting component for limiting the movement of the seedling raising tray 7 is provided in the mounting frame 2, and a watering component that can extend into the seedling raising tray 7 is provided in the mounting frame 2. The watering device provided in the present technical solution mainly solves the problem in the prior art that an atomizing nozzle sprays water mist onto the surface of the seeds, thereby watering the seeds. However, the watering in the above-mentioned manner is uneven, the amount of watering is not easy to control, and the operation is relatively cumbersome, which can easily cause the liquid inside the seedling raising tray 7 to be partially uneven, thereby affecting the germination rate of the seeds. In order to solve the above-mentioned problem, the present technical solution fastens the mounting frame 2 made of steel profiles to the outer frame of the conveying mechanism 1 of the seedling raising equipment by bolts, thereby ensuring that the watering device can enable the watering component to accurately pour water into the seedling raising tray 7 that moves toward the watering device through the conveying mechanism 1, thereby improving the uniform distribution of water in the seedling raising tray 7. The germination rate of seeds in the seedling tray 7 is improved; and the limiting component set can limit the seedling tray 7 in continuous motion, so that the seedling tray 7 is placed on the lower side of the water spraying area of ​​the watering component, which is convenient for the watering component to cover the surface of the seeds in the seedling tray 7 with water; and the watering component can be placed in the supporting material for supporting the seeds in the seedling tray 7, so that the moisture on the surface of the seeds and the moisture in the middle and lower layers of the seedling tray 7 are evenly distributed. Through the above structure, it can be ensured that the device can thoroughly water the seeds and the supporting material in the seedling tray 7, and also avoid the problem of high water content of the seeds and the supporting material, thereby improving the success rate of seed development.

[0027] In some technical solutions of the present application, the limiting component includes a blocking plate 15 slidably arranged in the mounting frame 2 along the vertical direction, and an electric push rod 19 connected to the blocking plate 15 is arranged in the mounting frame 2.

The watering pipes 4 are distributed in an array on the mounting plate 3. The watering pipes 4 are in the shape of a needle tube. When the driving component pushes the mounting plate 3 to move toward the seedling raising tray 7, the watering pipes 4 can penetrate into the supporting material, thereby directly introducing water into the supporting material to achieve the purpose of watering the supporting material thoroughly. The front end of the watering pipe 4 is in a cone or arc shape, which is convenient for the watering pipe 4 to penetrate into the supporting material. After the watering pipe 4 penetrates into the supporting material, holes will be left in the supporting material, which is convenient for the seeds in the seedling raising tray 7 to improve the ventilation capacity, and avoid the seeds from becoming moldy due to excessive moisture enrichment in the supporting material, thereby affecting the germination rate of the seeds. The atomizing nozzle 14 does not share a water channel with the watering pipe 4. The atomizing nozzle 14 uses a single conduit and an independent water pump to supply water, and the amount of water sprayed is small. In this way, the atomizing nozzle 14 can spray the surface of the seeds repeatedly to improve the germination rate of the seeds.

[0029] Furthermore, the number of the atomizing nozzles 14 is at least 3.
