[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-8A rice seedling raising device includes a base plate 1, on which a first upright plate 2 and a second upright plate 3 are mounted. A first connecting rod 4 and a second connecting rod 5 are rotatably connected to each other via pins on adjacent sides of the first upright plate 2 and the second upright plate 3. The center ends of the first connecting rod 4 and the second connecting rod 5 are rotatably connected to the pins. The first connecting rod 4 and the second connecting rod 5 are parallel to each other. A first seedling trough 6 is fixedly connected between the pins of the first upright plate 2 and the second upright plate 3. A second seedling trough 7 is movably connected to the same end of the two sets of first connecting rods 4 and second connecting rods 5. A third seedling trough 8 is movably connected to the other end of the first connecting rod 4 and the second connecting rod 5. A bidirectional lead screw 9 is vertically rotatably connected to the outer side of the first upright plate 2. A first moving block 10 is threadedly connected to the positive thread section of the bidirectional lead screw 9, and a second moving block 11 is threadedly connected to the negative thread section of the bidirectional lead screw 9. A first guide shaft 12 is provided on the first moving block 10 and is slidably connected to one end of the adjacent first connecting rod 4. A second guide shaft 13 is provided on the second moving block 11 and is slidably connected to one end of the adjacent second connecting rod 5.

[0026] In its initial state, the third seedling trough 8 is located above the first seedling trough 6, and the second seedling trough 7 is located below the first seedling trough 6. Because the first moving block 10 and the second moving block 11 are vertically distributed, and the first connecting rod 4 and the second connecting rod 5 are arranged parallel to each other, the third seedling trough 8 and the second seedling trough 7 cannot be perfectly vertically distributed with respect to the first seedling trough 6, and there is a certain tilt angle. Using a handwheel to drive the bidirectional lead screw 9 to rotate, the first moving block 10 and the second moving block 11 move synchronously towards each other on the bidirectional lead screw 9. The first moving block 10 drives the first guide shaft 12 to slide downwards within the first connecting rod 4, and the second moving block 11 drives the second guide shaft 13 to slide upwards within the second connecting rod 5, so that the first connecting rod 4 and the second connecting rod 5 are connected by a pin. The pivot point is tilted in the same direction, causing the third seedling trough 8 to move downward in an arc from above the first seedling trough 6 to one side, and the second seedling trough 7 to move upward in an arc from below the first seedling trough 6 to the other side. This achieves the staggered arrangement of the third seedling trough 8, the first seedling trough 6, and the second seedling trough 7, preventing sunlight from being blocked between the upper and lower layers, while providing sufficient growth space for the rice seedlings. Furthermore, the bidirectional screw 9, the first moving block 10, the second moving block 11, the first guide shaft 12, and the second guide shaft 13 ensure the stability of the third seedling trough 8, the first seedling trough 6, and the second seedling trough 7 after the staggered arrangement is adjusted, preventing the first connecting rod 4 and the second connecting rod 5 from rotating twice after the seedling trough is planted in the water trough.

[0027] Specifically, in this embodiment, diagonal braces 14 are provided at both right-angled ends of the base plate 1 and the first upright plate 2, as well as at both right-angled ends of the base plate 1 and the second upright plate 3, to improve the connection effect between the first upright plate 2 and the second upright plate 3 and the base plate 1, and to prevent the overall device from tipping over when the center of the third seedling trough 8, the first seedling trough 6 and the second seedling trough 7 are misaligned, thereby improving the overall stability of the seedling device structure.

[0028] Specifically, in this embodiment, the first moving block 10 is provided with a positive thread hole 15 that is adapted to the positive thread section of the bidirectional lead screw 9, and the second moving block 11 is provided with a negative thread hole 16 that is adapted to the negative thread section of the bidirectional lead screw 9, so as to realize the effect of synchronous relative movement of the first moving block 10 and the second moving block 11 by the unidirectional rotation of the bidirectional lead screw 9.

[0029] Specifically, in this embodiment, a first sliding groove 17 is provided on the first upright plate 2. The first sliding groove 17 is arranged vertically. The first moving block 10 and the second moving block 11 are slidably connected in the first sliding groove 17, providing a unified movement guide for the first moving block 10 and the second moving block 11. At the same time, the first moving block 10 and the second moving block 11 can pass through the first upright plate 2, respectively driving the first guide shaft 12 and the second guide shaft 13 to cooperate with the first connecting rod 4 and the second connecting rod 5.

[0030] Specifically, in this embodiment, the first connecting rod 4 has two first guide grooves 18, which are arranged along the longitudinal direction of the first connecting rod 4 and are symmetrical to each other. The first guide shaft 12 is arranged in one of the first guide grooves 18. The second connecting rod 5 has two second guide grooves 19, which are arranged along the longitudinal direction of the second connecting rod 5 and are symmetrical to each other. The second guide shaft 13 is arranged in one of the second guide grooves 19. The movement of the first guide shaft 12 in the first guide groove 18 in the tilted state and the movement of the second guide shaft 13 in the second guide groove 19 in the tilted state realize the rotation effect of the first connecting rod 4 and the second connecting rod 5 on the corresponding pin shafts.

[0031] Specifically, in this embodiment, a guide rod 20 is provided on the outer side of the second upright plate 3. The guide rod 20 is arranged parallel to the bidirectional lead screw 9. A first guide block 21 and a second guide block 22 are slidably connected to the guide rod 20. A third guide shaft 23 is provided on the first guide block 21. The third guide shaft 23 is slidably connected to one of the first guide grooves 18 on the adjacent first connecting rod 4. A fourth guide shaft 24 is provided on the second guide block 22. The fourth guide shaft 24 is slidably connected to one of the second guide grooves 19 on the adjacent second connecting rod 5. The cooperation of the first guide block 21 and the third guide shaft 23, the cooperation of the second guide block 22 and the fourth guide shaft 24, the cooperation of the first moving block 10 and the first guide shaft 12, and the cooperation of the second moving block 11 and the second guide shaft 13 realize the synchronous rotation effect of the two sets of first connecting rods 4 and second connecting rods 5, thereby improving the horizontal stability of the misalignment adjustment of the third seedling trough 8 and the second seedling trough 7.

[0032] Specifically, in this embodiment, a second sliding groove 25 is provided on the second upright plate 3. The second sliding groove 25 is arranged vertically. The first guide block 21 and the second guide block 22 are slidably connected in the second sliding groove 25 to ensure that the movement of the first guide block 21 and the second guide block 22 maintains the same movement trajectory as the first moving block 10 and the second moving block 11.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
