[0036] The agricultural greenhouse seedling raising device and the Internet-based smart agricultural seedling raising greenhouse according to embodiments of the present invention have the following beneficial effects:

[0037] 1. This device arranges several seedling boxes on a pair of rotating frames, with a water tank pre-stored with aqueous solution below each seedling box. The rotating frames drive the seedling boxes to rotate, immersing them in the aqueous solution in the tank, thus irrigating the crops growing in the seedling boxes. Utilizing the fact that impurities mixed in the aqueous solution tend to settle at the bottom of the tank, this effectively prevents impurities from clogging the water supply components of the device.

[0038] 2. This device uses a pair of rotating frames to rotate multiple seedling boxes, allowing users to adjust the suspension angle of the rotating frames according to the incident angle of light in the greenhouse. Additionally, the device uses an electric telescopic rod on the rotating frames to adjust the distance between a pair of long rods, thereby adjusting the relative positions of the seedling boxes on the rotating frames and ensuring that the crop seedlings in the boxes receive sufficient light.

[0039] 3. This device, by setting multiple water supply components in the seedling box and cooperating with the rotating bed frame, draws water from the water tank to irrigate the crop seedlings cultivated in the seedling trays mounted on the same supporting box. It can also use the water supply components to irrigate the crop seedlings cultivated in the seedling box located below it. There is no need to set up a separate irrigation mechanism to irrigate the crops cultivated in the seedling box rotatably connected to the middle section of the long rod, which simplifies the structure of the device and reduces its production cost.

[0057] Furthermore, such as Figure 1 , 3 As shown in Figures 4, 6, and 7, the seedling box 2 includes: a support box body 21, an assembly window 22, a seedling tray 23, a pair of clamping plates 24, a sponge filling material 25, and several water supply components; the support box body 21 is positioned between a pair of rotating bed frames 4, with both ends of the support box body 21 rotatably connected to the pair of rotating bed frames 4, and the top of the support box body 21 adopts an open design; the assembly window 22 is located at the bottom of the support box body 21 and communicates with the bottom of the inner cavity of the support box body 21; the seedling tray 23 is positioned in the top port of the support box body 21 and is snapped into the top port of the support box body 21; the pair of clamping plates 24 are respectively movably positioned at the bottom of the inner cavity of the support box body 21 along the radial direction of the support box body 21. One clamping plate 24 is located between the other clamping plate 24 and the seedling tray 23, and the radial cross-sectional shape of any clamping plate 24 matches the bottom of the inner cavity of the supporting box 21; the sponge filling material 25 is disposed between the pair of clamping plates 24; several water supply components are disposed on the pair of clamping plates 24, and the several water supply components are all connected to the inner cavity of the seedling tray 23; in this embodiment, the pair of seedling boxes 2 rotatably connected to the middle section of the long rod 41 are not provided with clamping plates 24, sponge filling material 25 and water supply components, so that after the crop seedlings cultivated in the seedling tray 23 of the pair of seedling boxes 2 rotatably connected to the middle section of the long rod 41 are watered, the seeping water solution can flow out through the drainage hole 231 and the assembly window 22 of the seedling tray 23 in sequence.

[0058] Furthermore, such as Figures 3-6 As shown, the water supply assembly includes: a pair of water supply holes 261 and a water supply rod 262; the pair of water supply holes 261 are respectively opened on a pair of clamps 24, and the position of any one of the water supply holes 261 corresponds to one of the drainage holes 231 of the seedling tray 23, and the diameter of the water supply hole 261 is smaller than the diameter of the drainage hole 231; the water supply rod 262 is movably inserted into the pair of water supply holes 261, the top end of the water supply rod 262 extends into the inner cavity of the seedling tray 23, and the bottom end of the water supply rod 262 protrudes from the bottom surface of the support box 21 through the assembly window 22.

[0059] Furthermore, such as Figures 3-5As shown in Figures 6 and 8, the water supply rod 262 includes: a connecting section 2621, a bottom limiting section 2622, and a top limiting section 2623; the two ends of the connecting section 2621 are fixedly connected to the bottom limiting section 2622 and the top limiting end, respectively. The central axes of the connecting section 2621, the bottom limiting section 2622, and the top limiting end are collinear. The connecting section 2621 is movably inserted into a pair of water supply holes 261; the bottom limiting section 2622 is located at the bottom end of the water supply rod 262, and the outer diameter of the bottom limiting section 2622 is larger than the diameter of the water supply hole 261; the top limiting section 2623 is located at the top end of the water supply rod 262, and the outer diameter of the top limiting section 2623 is larger than the diameter of the water supply hole 261, but not larger than the diameter of the drain hole 231.

[0060] Furthermore, such as Figure 5 , 6 As shown in Figure 8, the top end of the bottom limiting section 2622 is provided with a first rounded corner portion 26221, and the bottom end of the top limiting section 2623 is provided with a second rounded corner portion 26231. During the process of the water supply rod 262 pushing the clamping plate 24 located on the lower side to rise, the first rounded corner portion 26221 cooperates with the bottom port of the water supply hole 261 opened on the clamping plate 24 located on the lower side to block it. Similarly, during the process of the water supply rod 262 driving the clamping plate 24 located on the upper side to fall, the second rounded corner portion 26231 cooperates with the top port of the water supply hole 261 opened on the clamping plate 24 located on the upper side to block it.

[0061] Furthermore, such as Figure 5 , 6 As shown in Figure 8, the water supply rod 262 also includes: a plurality of guide grooves 2624, which are formed on the circumferential sidewall of the connecting section 2621. The plurality of guide grooves 2624 are arranged in a circumferential array around the central axis of the connecting section 2621. Any one of the guide grooves 2624 is arranged along the axial direction of the connecting section 2621. The outer diameter of the connecting section 2621 is equal to the diameter of the water supply hole 261.

[0062] Furthermore, such as Figure 3 , 6 As shown, the seedling box 2 also includes: a plurality of first positioning holes 27, a plurality of second positioning holes 28, and a plurality of positioning pins 29; the plurality of first positioning holes 27 are formed on the side wall of the supporting box body 21, and the plurality of first positioning holes 27 penetrate through the outer wall of the supporting box body 21 and communicate with the inner cavity of the supporting box body 21; the plurality of second positioning holes 28 are formed on the side wall of the seedling tray 23, and the plurality of second positioning holes 28 penetrate through the outer wall of the seedling tray 23 and communicate with the inner cavity of the seedling tray 23, and the positions of the plurality of second positioning holes 28 correspond one-to-one with the plurality of first positioning holes 27; the plurality of positioning pins 29 are respectively inserted into the plurality of first positioning holes 27 and the plurality of second positioning holes 28 for fixing the seedling tray 23 onto the supporting shell.

[0063] Furthermore, such as Figure 1 , 2 As shown in Figure 9, the rotating bed frame 4 includes: a pair of long rods 41, a pair of short rods 42, an active rod 43, a flipping motor 44, and an electric telescopic rod 45; the pair of long rods 41 are arranged in parallel, and both ends of any one long rod 41 and the middle section of the long rod 41 are rotatably connected to the seedling box 2; the pair of short rods 42 are set on the pair of long rods 41, and both ends of one short rod 42 are hinged to the head end of the pair of long rods 41, and both ends of the other short rod 42 are hinged to the tail end of the pair of long rods 41, and the pair of short rods 42 are arranged in parallel; the active rod 43 is set on the pair of long rods 41, and both ends of the pair of active rods 43 are hinged to the middle section of the pair of long rods 41, and the active rod 43 is rotatably connected to any one of the long rods 41. A pair of short rods 42 are arranged in parallel. The middle section of the active rod 43 is rotatably connected to the support bracket 1. One end of the electric telescopic rod 45 is rotatably connected to one end of one of the short rods 42. The rotatable connection between the electric telescopic rod 45 and the short rod 42 is located at the head end of one of the long rods 41. The other end of the electric telescopic rod 45 is rotatably connected to one end of the active rod 43. The rotatable connection between the electric telescopic rod 45 and the active rod 43 is located in the middle section of another long rod 41. This is used to adjust the distance between the pair of long rods 41. A flipping motor 44 is fixedly mounted on the support bracket 1. The drive end of the flipping motor 44 is connected to the middle section of the active rod 43. This is used to drive the active rod 43 to rotate.

[0064] Furthermore, such as Figure 1 As shown, the device also includes: several linear drive devices 5, which are fixedly mounted on the support bracket 1. Each linear drive device 5 is vertically mounted along the axial direction of the support bracket 1. The several linear drive devices 5 are connected to the water tank 3 and are used to drive the water tank 3 to move up and down along the axial direction of the support bracket 1.

[0065] When the agricultural greenhouse seedling raising device irrigates the crop seedlings cultivated in the seedling box 2, firstly, the flipping motors 44 of a pair of rotating bed frames 4 drive the connected active rods 43 to rotate. After the pair of rotating bed frames 4 rotates to the point where their long rods 41 are in a vertical position, the flipping motors 44 of the pair of rotating bed frames 4 stop running, locking the long rods 41 in a vertical position. This causes the pair of seedling boxes 2 at the bottom of the several seedling boxes 2 installed on the pair of rotating bed frames 4 to be in the lowest position. Then, several linear drive devices 5 drive the water tank 3 to rise, causing the bottom of the supporting box 21 to gradually immerse in the aqueous solution stored in the inner cavity of the water tank 3. The aqueous solution passes through the assembly window 22 in sequence. The water supply rod 262's guide channel 2624 enters the cavity between a pair of clamps 24, where it is absorbed by the sponge filling material 25, saturating the sponge filling material 25 with water. Next, as the water tank 3 rises further, the bottom wall of the inner cavity of the water tank 3 contacts the bottom end of the water supply rod 262, pushing the water supply rod 262 upwards. This causes the top of the bottom limiting section 2622 at the bottom end of the water supply rod 262 to block the water supply hole 261 on the clamp 24 near the assembly window 22. Furthermore, the top limiting section 2623 at the top of the water supply rod 262 extends through the drain hole 231 into the inner cavity of the seedling tray 23. As the water supply rod 262 rises further, the lower clamp 24... Pushed by the bottom limiting section 2622 of 62, the water tank 3 moves towards the upper clamping plate 24, causing the pair of clamping plates 24 to move closer together. This squeezes out the aqueous solution absorbed in the sponge filling 25 between the pair of clamping plates 24. As the cavity between the pair of clamping plates 24 decreases, the squeezed aqueous solution, under pressure, enters the inner cavity of the seedling tray 23 through the guide channel 2624 and is absorbed by the soil in the inner cavity of the seedling tray 23, thus completing the irrigation. After irrigation, the water tank 3 slowly descends under the drive of the linear drive device 5. During this process, the water supply rod 262 and the lower clamping plate 24 descend accordingly. After the lower clamping plate 24 descends to the bottom of the inner cavity of the supporting box 21, the water supply... The bottom limiting section 2622 of the rod 262 disengages from its water supply hole 261, and the aqueous solution stored in the water tank 3 enters the cavity between the pair of clamps 24 again through the guide groove 2624 of the water supply rod 262, so that the sponge filling 25 located between the pair of clamps 24 absorbs water and becomes saturated again. Then the water tank 3 continues to descend and completely disengages from the seedling box 2. A pair of rotating supports drive the multiple seedling boxes 2 set between the pair of rotating supports to rotate 180°, flipping the pair of seedling boxes 2 that have absorbed water to the top layer, and at the same time flipping the pair of seedling boxes 2 that were originally on the top layer to the bottom layer. Several linear drive devices 5 drive the water tank 3 to rise again to irrigate the pair of seedling boxes 2 that are currently on the bottom layer.After the pair of seedling boxes 2, saturated with water, are flipped to the top, the water supply rod 262 loses the support of the bottom wall of the inner cavity of the water tank 3. This causes the top limiting section 2623 of the water supply rod 262 to block the water supply hole 261 located on the upper side. Furthermore, the weight of the water supply rods 262 of the multiple water supply components is fully applied to the clamping plate 24 located on the upper side. This causes the clamping plate 24 located on the upper side to shift towards the bottom of the inner cavity of the supporting box 21, squeezing the sponge filling 25 between the pair of clamping plates 24 and squeezing out the absorbed aqueous solution. The squeezed aqueous solution flows out through the guide channel 2624, sequentially through the water supply hole 261 and the assembly window 22 on the lower clamping plate 24, and drips along the guide at the bottom of the water supply rod 262 onto the area below. The seedling tray 23 of the lower seedling box 2 allows for irrigation of the crops cultivated in the seedling box 2, which is rotatably connected to the middle section of the long rod 41. This eliminates the need for a separate irrigation mechanism, simplifying the device's structure and reducing production costs. Furthermore, as the upper clamping plate 24 moves towards the bottom of the inner cavity of the supporting box 21, the cavity between the seedling tray 23 and the upper clamping plate 24 gradually increases. Excess water in the soil within the seedling tray 23 can flow through the filter holes of the seedling tray 23 into the cavity between the upper clamping plate 24 and the seedling tray 23, preventing over-irrigation of the crops cultivated in the seedling tray 23.

[0066] Furthermore, another embodiment of the present invention proposes an Internet-based smart agricultural seedling greenhouse, including the above-mentioned agricultural greenhouse seedling device.

[0068] 1. This device arranges several seedling boxes on a pair of rotating frames, with a water tank pre-stored with aqueous solution below each seedling box. The rotating frames drive the seedling boxes to rotate, immersing them in the aqueous solution in the tank, thus irrigating the crops growing in the seedling boxes. Utilizing the fact that impurities mixed in the aqueous solution tend to settle at the bottom of the tank, this effectively prevents impurities from clogging the water supply components of the device. This solves the problem of existing rotating vertical seedling beds, where nozzles are easily clogged by large particles in the water or external pollution, requiring regular manual maintenance.

[0069] 2. This device uses a pair of rotating frames to rotate multiple seedling boxes, allowing users to adjust the suspension angle of the rotating frames according to the incident angle of light in the greenhouse. Additionally, the device uses an electric telescopic rod on the rotating frames to adjust the distance between a pair of long rods, thereby adjusting the relative positions of the seedling boxes on the rotating frames and ensuring that the crop seedlings in the boxes receive sufficient light.

[0070] 3. This device, by setting multiple water supply components in the seedling box and cooperating with the rotating bed frame, draws water from the water tank to irrigate the crop seedlings cultivated in the seedling trays mounted on the same supporting box. It can also use the water supply components to irrigate the crop seedlings cultivated in the seedling box located below it. There is no need to set up a separate irrigation mechanism to irrigate the crops cultivated in the seedling box rotatably connected to the middle section of the long rod, which simplifies the structure of the device and reduces its production cost.
