The water outlet end of the water guiding frame 114 faces the placing hopper 7. The water guiding frame 114 can discharge water into the placing hopper 7. A water spraying pipe 113 is fixedly connected to the left side of the top of the movable plate 6. The water outlet end of the water spraying pipe 113 faces the water guiding frame 114. The water inlet end of the water spraying pipe 113 is connected to the shaft part of the movable plate 6 and is in communication with the inside of the annular pipe 112. A four-way pipe 111 is fixedly connected to the middle of the left cross plate 5. The four ends of the four-way pipe 111 are respectively connected to the four annular pipes 112. A connecting pipe 11 is fixedly inserted through the middle of the left side of the box body 1. The right end of the connecting pipe 11 is rotatably connected to the middle of the four-way pipe 111.

[0033] Please refer toFigures 7-9 As shown, it further includes a splitting component installed between the movable plate 6 and the placing hopper 7. The splitting component includes a conical pusher 12, a filter screen 121, a driving component, and a helical gear ring 128. The conical pusher 12 is rotatably connected to the inner side of the placing hopper 7 along the circumferential direction. When the conical pusher 12 rotates, the conical pusher 12 can separate the soil from the placing hopper 7. Six filter screens 121 are fixedly inserted through the bottom of the conical pusher 12 at uniform intervals. The filter screen 121 can filter water. A helical gear ring 128 is fixedly connected to the upper part of the outer side of the conical pusher 12 along the circumferential direction. The helical gear ring 128 rotatably penetrates the placing hopper 7. A driving component is arranged on the movable plate 6. When the driving component operates, the driving component can drive the helical gear ring 128 to rotate; the driving component includes a frame 122, a rotating rod 123, a guide rail 124, an elastic telescopic rod 125, a contact rod 126, and a helical gear 127. Three frames 122 are fixedly inserted through the movable plate 6 at uniform intervals. The three frames 122 are respectively located on the left side of the three placing hoppers 7. The middle part of the right side of the frame 122 is rotatably inserted with a rotating rod 123. A helical gear 127 is fixedly sleeved on the right end of the rotating rod 123. The helical gear 127 meshes with the helical gear ring 128. When the helical gear 127 rotates, the helical gear 127 can drive the helical gear ring 128 to rotate. The left end of the rotating rod 123 is fixedly connected to an elastic telescopic rod 125. The middle part of the right side of the elastic telescopic rod 125 is fixedly connected to a contact rod 126. Three guide rails 124 are fixedly connected to the top of the movable plate 6 at uniform intervals. The guide rail 124 is composed of a straight section and an arc section. The inner side of the guide rail 124 is slidably connected to the contact rod 126.

[0034] Initially, the connecting pipe 11 is externally connected to a water source. First, pull the box door 2 to swing forward and open it. Then, put the crop seedlings into the placing hopper 7 at the front directly, and pour soil into the placing hopper 7 at the front directly to cover the roots of the crop seedlings. When the crop seedlings are planted in the placing hopper 7 at the front directly, start the driving motor 41 to drive the rotating shaft 4 to rotate. The rotating shaft 4 drives the cross plate 5 to rotate. The cross plate 5 drives the placing hopper 7 to rotate through the movable plate 6. When the next group of placing hoppers 7 rotates to the front directly, turn off the driving motor 41. According to the above operation, the crop seedlings can be continuously planted in the placing hopper 7. When all the placing hoppers 7 are planted with crop seedlings, pull the box door 2 to swing backward and close it. Then, drain water into the connecting pipe 11. The water in the connecting pipe 11 is drained into the four-way pipe 111. The water in the four-way pipe 111 is drained into the annular pipe 112. The water in the annular pipe 112 is drained into the water spraying pipe 113. The water in the water spraying pipe 113 is drained into the water guiding frame 114. The water in the water guiding frame 114 is drained into the placing hopper 7 to contact the soil. The water penetrates into the soil to supply water to the crop seedlings. Part of the water that is not absorbed passes through the filter net 121 and drops downward into the box body 1. When an appropriate amount of water is supplied to the soil, stop draining water into the connecting pipe 11. Then, start the lighting lamp 31. The lighting lamp 31 irradiates the crop seedlings, which enables the crop seedlings to carry out photosynthesis, completing the seedling raising treatment of the crop seedlings. At the same time, start the driving motor 41 to drive the rotating shaft 4 to rotate continuously. The rotating shaft 4 drives the cross plate 5 to rotate. The cross plate 5 drives the guiding gear 8 and the movable plate 6 to rotate circumferentially along the box body 1. The movable plate 6 drives the driving gear 9 and the placing hopper 7 to rotate circumferentially along the box body 1. The guiding gear 8 rotates self-drivenly through the fixed gear 10. The self-rotation of the guiding gear 8 drives the self-rotation of the driving gear 9. The driving gear 9 drives the self-rotation of the movable plate 6, which enables the movable plate 6 to always be in a vertical state. The movable plate 6 enables the placing hopper 7 to always be in a vertical state. The rotation of the placing hopper 7 and always being in a vertical state drives the crop seedlings to rotate. When the crop seedlings rotate to the upper part, the crop seedlings are close to the lighting lamp 31 and are irradiated to carry out photosynthesis. In this way, all the crop seedlings can evenly receive the light amount for photosynthesis, thereby improving the seedling raising effect. At the same time, water can be regularly drained into the connecting pipe 11, so that the water guiding frame 114 drains water into the placing hopper 7 to supply water to the crops, and the ventilation in the box body 1 can be ensured through the shutter 3.After the crop seedling raising is completed, turn off the driving motor 41, and the movable plate 6 stops driving the crop seedlings to rotate through the placing hopper 7. Then turn off the lighting lamp 31. Subsequently, first pull the elastic telescopic rod 125 to contract, driving the contact rod 126 to move forward. When the contact rod 126 moves forward and contacts the arc section of the guide rail 124, stop pulling the elastic telescopic rod 125 to drive the contact rod 126 to move forward. Then, it is possible to pull the elastic telescopic rod 125 to drive the contact rod 126 to swing forward. The guide rail 124 guides the contact rod 126. The forward swing of the elastic telescopic rod 125 drives the rotating rod 123 to reverse. The reverse rotation of the rotating rod 123 drives the helical gear 127 to reverse. The reverse rotation of the helical gear 127 drives the helical gear ring 128 to rotate forward. The forward rotation of the helical gear ring 128 drives the conical pusher 12 to rotate forward, and the forward rotation of the conical pusher 12 divides the position where the soil adheres to the placing hopper 7. When the contact rod 126 swings forward to the maximum stroke within the guide rail 124, the separation of the soil from the placing hopper 7 is completed. Then, pull the elastic telescopic rod 125 to swing backward, driving the contact rod 126 to swing backward. At the same time, the elastic telescopic rod 125 drives the rotating rod 123 to rotate forward. The forward rotation of the rotating rod 123 drives the helical gear 127 to rotate forward. The forward rotation of the helical gear 127 drives the helical gear ring 128 to reverse. The reverse rotation of the helical gear ring 128 drives the conical pusher 12 to reverse and reset. Then release the elastic telescopic rod 125. Due to the elastic action of the elastic telescopic rod 125, the elastic telescopic rod 125 moves backward and resets, driving the contact rod 126 to move backward and reset. The contact rod 126 resets and continues to be within the straight section of the guide rail 124. The operator can easily take out the cultivated crop seedlings from the placing hopper 7. In this way, it is more convenient for the operator to take out the cultivated crop seedlings from the placing hopper 7, thereby improving the feeding efficiency.

[0035] Please refer to Figure 10 and Figure 11As shown in the figure, the crop seedling raising device further includes a control component installed on the movable plate 6. The control component includes a vertical rod 13, a closing plate 132, a mounting frame 133, a sponge strip 134, an electric screw rod 135, an opening and closing component, and a humidity sensor 1310. Three vertical rods 13 are fixedly connected to the bottom of the movable plate 6 at equal intervals. The three vertical rods 13 correspond to the three placement hoppers 7 respectively. A closing plate 132 is slidably sleeved between each group of vertical rods 13. The closing plate 132 contacts the bottom of the placement hopper 7, and the closing plate 132 can close the placement hopper 7. Three electric screw rods 135 are vertically installed on the front side of the movable plate 6 at equal intervals. The electric screw rod 135 is threadedly connected to the right front side of the closing plate 132. A humidity sensor 1310 is embedded in the inner wall of the placement hopper 7. The humidity sensor 1310 is electrically connected to the electric screw rod 135 through a control module. A mounting frame 133 is installed at the bottom of the movable plate 6. The mounting frame 133 is located below the closing plate 132. Sponge strips 134 are placed at equal intervals inside the mounting frame 133. The sponge strips 134 can absorb the dropped water. An opening and closing component is provided between the movable plate 6 and the closing plate 132. When the opening and closing component operates, the opening and closing component can control the water in the water guide frame 114. The opening and closing component includes a guide frame 136, a slotted rod 137, a convex block 138, and an opening and closing block 139. Three guide frames 136 are fixedly connected to the rear side of the bottom of the movable plate 6 at equal intervals. A slotted rod 137 is rotatably connected to the inside of each of the three guide frames 136. The slot of the slotted rod 137 consists of a vertical section and a spiral section. The left rear side of the closing plate 132 is slidably sleeved on the slotted rod 137. The top of the slotted rod 137 rotatably penetrates the bottom of the water guide frame 114. An opening and closing block 139 is fixedly connected to the top of the slotted rod 137. When the opening and closing block 139 rotates, the opening and closing block 139 can control the water in the water guide frame 114. Three convex blocks 138 are fixedly connected to the left rear side of the top of the closing plate 132 at equal intervals. The three convex blocks 138 are all located in the slot of the slotted rod 137. When the convex block 138 moves downward and contacts the spiral section of the slotted rod 137, the convex block 138 can drive the slotted rod 137 to rotate.

[0036] When water is drained into the water guide frame 114, the water in the water guide frame 114 contacts the opening and closing block 139. The water guide frame 114 drains the water into the placement hopper 7, and the water penetrates into the soil to supply water to the crop seedlings. At the same time, the humidity sensor 1310 monitors the humidity of the soil. When the humidity sensor 1310 detects that the humidity of the soil exceeds the set maximum value, the humidity sensor 1310 controls the electric lead screw 135 to rotate forward through the control module. The forward rotation of the electric lead screw 135 drives the closing plate 132 to move downward. The downward movement of the closing plate 132 disengages from the placement hopper 7, and the closing plate 132 stops closing the placement hopper 7. Part of the water in the placement hopper 7 will be discharged and fall onto the closing plate 132, thereby reducing the humidity of the soil. The closing plate 132 discharges the water and falls onto the sponge strip 134, and the sponge strip 134 absorbs the water. At the same time, the downward movement of the closing plate 132 drives the convex block 138 to move downward. When the convex block 138 moves downward and contacts the spiral section of the grooved rod 137, the convex block 138 drives the grooved rod 137 to rotate 90 degrees. The grooved rod 137 drives the opening and closing block 139 to rotate 90 degrees. The 90-degree rotation of the opening and closing block 139 closes the position of the water guide frame 114 corresponding to the relatively high soil humidity, and the water in the water guide frame 114 will not be drained into the soil with relatively high humidity. Instead, the water guide frame 114 continues to drain the water into the remaining two placement hoppers 7. The electric lead screw 135 is turned off, and the closing plate 132 stops moving downward. The closing plate 132 stops driving the convex block 138 to move downward. When the soil humidity returns to the standard value, the humidity sensor 1310 controls the electric lead screw 135 to rotate reversely through the control module. The reverse rotation of the electric lead screw 135 drives the closing plate 132 to move upward and reset. The upward movement of the closing plate 132 to reset continues to close the placement hopper 7. The upward movement of the closing plate 132 drives the convex block 138 to move upward. The upward movement of the convex block 138 drives the grooved rod 137 to rotate reversely 90 degrees to reset. The grooved rod 137 drives the opening and closing block 139 to rotate reversely 90 degrees to reset. The reset of the opening and closing block 139 stops closing the water guide frame 114. The water in the water guide frame 114 continues to flow into the placement hopper 7 and penetrates into the soil, thereby continuing to supply water to the crop seedlings. When the sponge strip 134 has been used for a long time, the sponge strip 134 can be taken out of the installation frame 133 for drying and then put back into the installation frame 133. In this way, it is possible to prevent the humidity in the soil from exceeding the humidity that the crop seedlings can withstand and affecting the growth of the crop seedlings, thereby improving the safety of crop seedling raising.

[0037] Please refer to Figure 12 As shown, the crop seedling raising device further includes an exhaust fan 14. The exhaust fan 14 is installed at the rear side inside the box body 1. The exhaust fan 14 is located in front of the rear side louvers 3. When the exhaust fan 14 rotates, the exhaust fan 14 can extract the air inside the box body 1 to complete the automatic ventilation of the box body 1.

[0038] When cultivating crop seedlings, start the exhaust fan 14. The exhaust fan 14 extracts the air in the box body 1 through the rear shutter 3, which makes the air in the box body 1 flow faster, thereby improving the ventilation effect in the box body 1.

[0039] Finally, it is necessary to note that the above content is only used to help understand the technical solution of the present invention and should not be construed as a limitation on the protection scope of the present invention; any non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention fall within the scope of protection required by the present invention.
