However, in this device, multiple layers of "trays" are stacked vertically, resulting in the trays arranged on the upper side blocking the light of the seedlings in the tray on the lower side, resulting in the lower seedlings not being able to receive sufficient light, and thus growing slower than the upper seedlings, reducing the quality of rice seedlings, and having disadvantages. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a rice seedling raising device which is convenient for transplanting rice seedlings and can adjust the longitudinal support distance between seedling raising trays according to the actual growth height of the rice seedlings, thereby ensuring sufficient growth space for the rice seedlings and preventing the seedlings from being crushed. In addition, the seedling raising trays can be flexibly arranged, and the longitudinal staggered arrangement can reduce the light blocking to the lower seedling layer, thereby ensuring sufficient light for the seedlings, accelerating the growth of the seedlings, and improving the quality of the rice seedlings. The utility model can also reduce the overall storage space of the seedling raising rack by longitudinally arranging the seedlings in a straight line.

Beneficial Effects

[0008] The utility model adopts a split design between the seedling tray and the supporting tray, which is convenient for quick taking during transplanting and improves the efficiency of rice seedling transplanting. A plurality of water permeable holes are provided at the bottom of the seedling tray, which is convenient for the nutrient solution and other water contained in the water storage tray to penetrate into the root system of the rice seedlings, which is beneficial for the seedlings to absorb nutrients and accelerate the growth of the seedlings. When the seedling tray is transplanted, the excess water in the root system of the seedling tray can be quickly drained out through the water permeable holes and discharged into the water storage tray, reducing the loss of nutrient liquid. The water storage tray is fixedly connected to the installation support sleeve by a thread, and is easy to disassemble and assemble, so that the nutrient solution and other water in the water storage tray can be regularly dumped and replaced, and the operation is convenient.

[0009] The positioning support sleeve of the utility model has a support plate and a pressure plate for clamping and supporting the upper and lower sides of the rotating plate, thereby improving the stability of the supporting force of the support tray and preventing the seedling tray from tipping over. At the same time, the positioning support sleeve is positioned and connected to the positioning column through a thread, so that the longitudinal support distance between the seedling trays can be adjusted accordingly according to the actual growth height of the rice seedlings, thereby ensuring that the rice seedlings have sufficient growth space and preventing the seedlings from being crushed.

[0010] The utility model has a plurality of groups of positioning lock grooves evenly distributed on the axial direction of the rotating plate, which cooperate with the positioning lock block to increase the positioning fulcrum between the pressure plate and the rotating plate. When the positioning lock block is driven to move to the position where it is embedded in the positioning lock groove by turning the knob, the rotating plate is braked and locked and cannot be rotated on the support plate. At this time, the support plate can be supported in the direction where the support plate is located. When the positioning lock block is driven to move to the position where it is stored in the storage groove by turning the knob in the opposite direction, the positioning fulcrum of the rotating plate on the pressure plate disappears. At this time, the rotating plate can be rotated to change the supporting direction of the support plate. The structure is flexible and the operation is convenient.

[0011] The utility model can prevent the seedling trays on the upper layer from blocking the light of the seedlings on the lower layer when multiple groups of seedling trays are in a longitudinal staggered state, so that the rice seedlings on the lower layer can be exposed to sufficient light, the growth of the seedlings can be accelerated, and the quality of the rice seedlings can be improved. When multiple groups of seedling trays are in a longitudinal straight line arrangement, the overall storage space of the seedling rack can be reduced, and the structure is flexible.

[0012] The utility model is convenient for transplanting rice seedlings, and can adjust the longitudinal support distance between the seedling trays according to the actual growth height of the rice seedlings, so as to ensure that the rice seedlings have sufficient growth space and prevent the seedlings from being crushed. In addition, the arrangement of the seedling trays is flexible, and the longitudinal staggered arrangement can reduce the blocking of light to the lower seedling layer, thereby ensuring sufficient light for the seedlings, accelerating the growth of the seedlings, and improving the quality of the rice seedlings. The longitudinal straight arrangement can also reduce the overall storage space of the seedling rack. BRIEF DESCRIPTION OF THE DRAWINGS
