[0036] The support assembly 2 also includes a locking bolt 24, the insertion sleeve 23 is threaded with the locking bolt 24 on the outside of the insertion end of the insertion rod 22, and the locking bolt 24 is in extrusion contact with the insertion rod 22 inserted into the insertion sleeve 23. The insertion sleeve 23 at the bottom of the support assembly 2 outside the second side plate 12 is installed with a moving wheel 25, and the insertion sleeve 23 at the bottom of the support assembly 2 outside the first side plate 11 is fixed with a fixed foot 26. The cultivation tray body is connected by the insertion of the insertion sleeve 23 and the insertion rod 22 and the top plate 21, forming a vertical support frame. The bottom of the insertion rod 22 is inserted into the lower end of the insertion sleeve 23, and the top of the insertion rod 22 is fixedly connected with the upper end of the insertion sleeve 23 or the top plate 21. The insertion position of the insertion sleeve 23 corresponding to the insertion rod 22 can be locked by the locking bolt 24, which can be adjusted according to the growth height of soybean seedlings, so as to avoid the influence of the distance between the upper and lower cultivation tray bodies 1 on the growth of soybean seedlings. At the same time, the bottom moving wheel 25 of the support assembly 2 outside the second side plate 12 can facilitate the movement of the second side plate 12 by cooperating with the advancing assembly 4, and the fixed foot 26 on the other side can be fixed on the ground to keep the position of the first side plate 11 unchanged, thereby facilitating the staggered expansion of the four cultivation frames.

[0037] The lighting assembly 3 also includes a telescopic plate 38 in this embodiment, which is fixed between the adjacent front light plate 31 and the adjacent rear light plate 32. The bottom of the front light plate 31 at the end of the lighting assembly 3 away from the advancing assembly 4 is fixed with a fixed block 39, which is fixedly connected with the second side plate 12. The side of the front light plate 31 at both ends of the lighting assembly 3 is provided with a moving groove 34, and the moving groove 34 is slidably connected with a moving block 35 inside. The outer side of the moving block 35 is rotatably connected with a first connecting rod 36 through a rotating shaft. The other end of the first connecting rod 36 is rotatably connected with the rear light plate 32. The top of the rear light plate 32 at the other end of the lighting assembly 3 is rotatably connected with a second connecting rod 37 through a rotating shaft, and the top of the second connecting rod 37 is rotatably connected with the top of the upper end or the second side plate 12. Here, the front light plate 31 and the rear light plate 32 are composed of multiple plates, and the rear light plate 32 is folded at the rear end of the front light plate 31. When the distance between the upper and lower groups of seedling tray bodies 1 is not adjusted, the rear light plate 32 does not need to be unfolded, and only the front light plate 31 needs to be opened to meet the light cultivation of soybean seedlings in the seedling tray bodies 1 from both sides. Under the pushing action of the advancing assembly 4, the second side plate 12 of all the seedling tray ladders moves horizontally forward. At this time, because the fixed block 39 is connected with the front light plate 31, and the top of the fixed block 39 is connected with the corresponding rear light plate 32 through the first connecting rod 36, the front light plate 31 and the rear light plate 32 will move and unfold synchronously with the second side plate 12, corresponding to the outermost end of the second side plate 12. The telescopic plate 38 maintains the connectivity of the adjacent front light plate 31 and rear light plate 32. At the same time, because the end of the rear light plate 32 close to the advancing assembly 4 is rotatably connected with the second side plate 12 at the upper end or the top plate 21 through the second connecting plate, and the rear light plate 32 at this position is also connected with the front light plate 31 through the first connecting rod 36, the front light plate 31 and the rear light plate 32 at the position of the second connecting rod 37 remain stationary, corresponding to the frontmost end of the first side plate 11. With the movement of the second side plate 12, the four groups of cultivation frames will be unfolded in a staggered manner. At this time, the length of the cultivation tray is lengthened, and the lighting assembly 3 maintains the same length by unfolding the front light plate 31 and the rear light plate 32, thereby maintaining the light irradiation effect on the whole range of soybean seedlings on the cultivation tray body. When the distance between the upper and lower groups of cultivation trays is adjusted by the supporting assembly 2, the front light plate 31 remains stationary in connection with the second side plate 12 due to the fixed block 39. The rear light plate 32 moves upward by pulling the second connecting rod 37, and the first connecting rod 36 drives the moving block 35 to slide along the moving groove 34, thereby maintaining the connection between the front light plate 31 and the rear light plate 32. Therefore, after adjusting the distance between the upper and lower groups of cultivation trays, the light irradiation requirement of soybean seedlings at different heights can be met by unfolding the front light plate 31 and the rear light plate 32.

[0038] When the device is used, soybean seeds are planted in the planting groove 16 of each seedling raising frame 13 for cultivation. The cultivation frame slides along the long plate 14 on both sides through the first insertion plate 110 at the bottom and the sliding frame 15, keeps the first side plate 11 position unchanged, and moves the second side plate 12 horizontally. When the second side plate 12 moves horizontally, the two rotating shaft seats drive the long plate 14 to rotate. At this time, the sliding frame 15 and the first insertion plate 110 connected with the long plate 14 move inside the insertion frame 19. Four groups of cultivation frames are staggered and unfolded. The part of the inner soybean seedlings that is blocked by the outer soybean seedlings is exposed. Because part of the length of the long plate 14 penetrates the rotating seat 111, the rotating groove 17 can avoid the interference of the rotation of the long plate 14. The rotating seat 111 can penetrate the sliding of the long plate 14. When the second side plate 12 translates, the connection between the first side plate 11, the second side plate 12 and the long plate 14 can be maintained to avoid movement interference. The cultivation disc body is connected through the insertion of the insertion sleeve 23 and the insertion rod 22 and the top plate 21 to form a vertical support frame. The bottom of the insertion rod 22 is inserted into the lower end of the insertion sleeve 23. The top of the insertion rod 22 is fixedly connected with the upper end of the insertion sleeve 23 or the top plate 21. The insertion sleeve 23 corresponding to the insertion position of the insertion rod 22 can be locked by the locking bolt 24 for adjustment according to the growth height of the soybean seedlings to avoid the distance between the upper and lower seedling cultivation disc bodies 1 affecting the growth of the soybean seedlings. At the same time, the bottom moving wheel 25 of the second side plate 12 outside the support assembly 2 can facilitate the pushing of the second side plate 12 by the pushing assembly 4. The fixed foot 26 on the other side can be fixed on the ground to keep the first side plate 11 position unchanged, thereby facilitating the staggered unfolding of the four groups of cultivation frames. When the support assembly 2 adjusts the distance between the cultivation disc bodies, the outside connecting plate 42 keeps the connectivity of the upper and lower horizontal plates 41 through the second insertion plate 43. Similarly, the inside connecting plate 44 is also connected through the second insertion plate 43 to adapt to the cultivation disc bodies with different height intervals. By rotating the screw rod 45, the inside connecting plate 44 is moved. The inside connecting plate 44 drives the second side plate 12 to move horizontally forward, which is staggered with the first side plate 11 to stagger and unfold the four groups of cultivation frames inside. It is convenient to eliminate the shielding of the inner soybean seedlings by the outer soybean seedlings. When the distance between the upper and lower two groups of seedling cultivation disc bodies 1 is not adjusted, the rear light plate 32 does not need to be unfolded. Only the front light plate 31 needs to be turned on to meet the light cultivation of the soybean seedlings in the seedling cultivation disc body 1 from both sides. Under the pushing action of the pushing assembly 4, all the second side plates 12 of the seedling cultivation disc ladders move horizontally forward. At this time, because the fixed block 39 is connected with the front light plate 31, and the front light plate 31 at the top of the fixed block 39 is connected with the rear light plate 32 behind through the first connecting rod 36, the front light plate 31 and the rear light plate 32 will move and unfold synchronously with the second side plate 12. The telescopic plate 38 keeps the connectivity of the adjacent front light plate 31 and rear light plate 32. At the same time, because the end of the rear light plate 32 close to the pushing assembly 4 is rotationally connected with the upper end of the second side plate 12 or the top plate 21 through the second connecting plate,The rear light board 32 at the position is also connected with the front light board 31 through the first connecting rod 36, so the front light board 31 and the rear light board 32 at the position of the second connecting rod 37 keep the position unchanged and correspond to the most front end of the first side plate 11, with the movement of the second side plate 12, the four groups of cultivation frames will be misaligned and unfolded, at this time, the length of the cultivation disc is lengthened, the lighting assembly 3 keeps the same length with the cultivation disc through the unfolding of the front light board 31 and the rear light board 32, and keeps the light irradiation on the whole range of the soybean seedlings on the cultivation disc body, when the supporting assembly 2 adjusts the distance between the upper and lower cultivation disc bodies, because of the fixed block 39, the front light board 31 keeps the connection with the second side plate 12 unchanged, the rear light board 32 is pulled upward through the second connecting rod 37, and the first connecting rod 36 drives the moving block 35 to slide along the moving groove 34, so the connection relationship between the front light board 31 and the rear light board 32 is kept, so after adjusting the distance between the upper and lower cultivation disc bodies, the light irradiation requirement of the soybean seedlings of different heights can be met through the unfolding of the front light board 31 and the rear light board 32.
