When the temperature is low at night, the seedlings cultivated in the seedling tube 4 can be kept warm, and at the same time, the seedlings can be prevented from being rained on in rainy weather.

[0064] A fixing block 10 is fixedly connected to the upper surface of the top plate 9, and the longitudinal section of the fixing block 10 is a triangle. A solar panel 11 is fixedly connected to the inclined surface of the fixing block 10, and the solar panel 11 is electrically connected to the plant growth lamp 8. A battery is fixedly connected to the lower surface of the top plate 9, and the wires on the solar panel 11 are electrically connected to the plant growth lamp 8 through the battery, so that the solar panel 11 can convert solar energy into electrical energy and store it in the battery, thereby facilitating the plant growth lamp 8 to provide light for the plants at night and promote the growth of seedlings.

[0065] The support frame 3 includes a horizontal rod 12 and a vertical rod 13 .

[0066] There are two cross bars 12 symmetrically arranged about the vertical bar 13 . When the support frame 3 is in a vertical position, the two cross bars 12 are respectively located at the top and the bottom of the vertical bar 13 .

[0067] There are at least two vertical rods 13 , and the ends of the vertical rods 13 are fixedly connected to the cross rod 12 , and the vertical rods 13 and the cross rod 12 are perpendicular to each other.

[0068] At least two seedling tubes 4 are arranged between two adjacent vertical rods 13, and a connecting shaft 14 is fixedly connected to the outer ring wall of the seedling tube 4, and the end of the connecting shaft 14 is rotatably connected to the side wall of the vertical rod 13. There are at least two seedling tubes 4, and each group of seedling tubes 4 is distributed between two adjacent vertical rods 13. There are at least two seedling tubes 4 in each group. When the support frame 3 is in a vertical state, multiple groups of seedling tubes 4 are arranged horizontally, and multiple seedling tubes 4 in each group are distributed vertically, which is convenient for growing seedlings of plants.

[0069] The interior of the base 1 is hollow, and a first partition 15 is horizontally fixedly connected to the interior of the base 1. The first partition 15 divides the interior of the base 1 from top to bottom into a driving chamber 16 and a water storage chamber 17. The winding roller 6 is horizontally rotatably connected to the side wall of the driving chamber 16, and the lower end face of the protective plate 7 is fixedly connected to the circumferential wall of the winding roller 6.

[0070] A first servo motor 18 is fixedly connected to the bottom of the driving chamber 16, and a first sprocket 19 is fixedly connected to the output shaft of the first servo motor 18 and the winding roller 6, and a first chain 20 is sleeved on two adjacent first sprockets 19, and a transmission shaft is fixedly connected to the winding roller 6, and a first sprocket 19 is fixedly connected to the end of the transmission shaft, wherein two first sprockets 19 are fixedly connected to the output shaft of the first servo motor 18, and the two first sprockets 19 are respectively connected to the first sprocket 19 on the transmission shaft through the first chain 20, so that the output shaft of the first servo motor 18 drives the winding roller 6 to rotate forward and reverse through the cooperation of the first sprocket 19 and the first chain 20, so as to facilitate the winding roller 6 to unfold and reel in the protective plate 7.

[0071] The protective plate 7 is made of a flexible material, and the protective plate 7 includes a waterproof layer, a heat-insulating layer and a reflective layer. When the protective plate 7 is covered on the end of the fixed plate 2, the outer layer of the protective plate 7 is a protective layer, the middle layer is a heat-insulating layer, and the opposite sides of the two protective plates 7 are reflective layers. When the support frame 3 is in a vertical state, the protective plate 7 is covered on the end of the fixed plate 2, and a seedling box is formed between the protective plate 7 and the fixed plate 2, the base 1, and the top plate 9. In rainy weather, the waterproof layer of the protective plate 7 can prevent rainwater from penetrating into the seedling box through the protective plate 7. Since the seedling box is closed on all sides, the light inside is dim, which is not conducive to plant growth. At this time, the plant growth lamp 8 is turned on, and the light emitted by the plant growth lamp 8 is reflected by the reflective layer of the protective plate 7, thereby further improving the brightness inside the seedling box and promoting plant growth.

[0072] A connecting rod 21 is fixedly connected to the upper end surface of the protection plate 7 .

[0073] A strip slide groove 22 is opened on the side wall of the fixed plate 2, and a lead screw 23 is rotatably connected to the bottom of the strip slide groove 22.

The lower end of the rotating shaft 24 passes through the bottom of the strip-shaped slide groove 22 and extends into the driving chamber 16 . The lower end of the rotating shaft 24 is rotatably connected to the bottom of the strip-shaped slide groove 22 .

[0075] A second servo motor 25 is fixedly connected to the bottom of the driving chamber 16 . A second sprocket 26 is fixedly connected to the output shaft of the second servo motor 25 and the rotating shaft 24 . A second chain 27 is sleeved on two adjacent second sprockets 26 .

[0077] A rotating rod 31 is rotatably connected to the inner wall of the control room 30, and a control rope 32 is wound on the rotating rod 31. The lower end of the control rope 32 passes through the bottom of the control room 30 and is fixedly connected to the upper end of the support frame 3. There are multiple control ropes 32, and the lower ends of the control ropes 32 are fixedly connected to the cross bar 12, and the fixed position of the control rope 32 corresponds to the position of the vertical bar 13.

[0078] A third servo motor 36 is fixedly connected to the upper surface of the base 1 , and a first gear 37 is fixedly connected to the output shaft of the third servo motor 36 .

[0079] A rotating shaft 38 is fixedly connected to the lower end of the support frame 3 , and a second gear 39 is fixedly connected to the rotating shaft 38 . The second gear 39 meshes with the first gear 37 .

[0080] A third sprocket 40 is fixedly connected to the output shaft of the third servo motor 36 and the rotating rod 31. A third chain 41 is sleeved on the third sprocket 40. The diameter of the second gear 39 is greater than the diameter of the first gear 37, and the number of teeth on the second gear 39 is greater than the number of teeth on the first gear 37. When the control rope 32 on the rotating rod 31 is fully extended, the support frame 3 is in a horizontal state.

[0081] A strip-shaped rainwater collecting groove 33 is provided on the upper surface of the top plate 9 , and the strip-shaped rainwater collecting groove 33 is located at the lower end of the solar panel 11 . A drainage hole 35 is provided on the side wall of the strip-shaped rainwater collecting groove 33 , and the drainage hole 35 is connected to the rainwater collecting chamber 29 .

[0082] A drainage pipe 34 is fixedly connected to the bottom of the rainwater collection chamber 29, a water storage chamber 48 is opened in the fixed plate 2, the lower end of the drainage pipe 34 passes through the control chamber 30 and is connected to the water storage chamber 48, and a check valve is arranged in the drainage pipe 34 to prevent the water in the water storage chamber 48 from flowing back into the rainwater collection chamber 29 through the drainage pipe 34.

[0083] The end of the rotating shaft 38 passes through the side wall of the fixed plate 2 and extends into the water storage chamber 48. The rotating shaft 38 is hollow. The top of the rotating shaft 38 and the vertical rod 13 are provided with interconnected through holes 42. The bottom of the water storage chamber 48 is fixedly connected with a connecting pipe. The lower end of the connecting pipe passes through the bottom of the driving chamber 16 and extends into the water storage chamber 17, so that the water in the water storage chamber 48 flows into the water storage chamber 17 through the connecting pipe, thereby facilitating the storage of the collected rainwater.

[0084] A water inlet hole 43 is provided on the side wall of the connecting shaft 14, one end of the water inlet hole 43 is connected to the through hole 42 on the vertical rod 13, and the other end of the water inlet hole 43 is connected to the seedling tube 4. An automatic control valve 45 is fixedly connected to the side wall of the water inlet hole 43 to facilitate the transportation of water into the seedling tube 4, thereby watering the seedlings in the seedling tube 4.

[0085] A plurality of water seepage holes 44 are provided at the bottom of the seedling raising tube 4 , and the water seepage holes 44 are communicated with the water storage box 5 .

[0086] The water storage box 5 is slidably connected to the outer side of the seedling tube 4, a spring 46 is arranged between the water storage box 5 and the seedling tube 4, and a gravity sensor 47 is fixedly connected to the water storage box 5, the gravity sensor 47 is connected to the automatic control valve 45 through a signal, the upper end of the spring 46 is fixedly connected to the connecting shaft 14, and the lower end of the spring 46 is fixedly connected to the upper surface of the water storage box 5. When water accumulates in the water storage box 5, the weight of the water storage box 5 increases, and the water storage box 5 pulls the lower end of the spring 46 downward through the action of gravity. When the water in the water storage box 5 evaporates, the weight of the water storage box 5 decreases. At this time, the water storage box 5 is pulled upward through the elastic force of the spring 46, so that the position of the water storage box 5 is restored.

[0087] Working principle: Pour nutrient soil into the seedling tube 4, and then bury the seeds to be cultivated in the nutrient soil in the seedling tube 4. When the buried seeds are photophobic seeds such as amaranth seeds, the staff starts the third servo motor 36 at this time. The output shaft of the third servo motor 36 drives the second gear 39 to rotate through the meshing of the first gear 37. Since the number of teeth on the second gear 39 is greater than the number of teeth on the first gear 37, the rotation speed of the second gear 39 is less than the rotation speed of the first gear 37 during the process of the first gear 37 driving the second gear 39 to rotate, so that the support frames 3 on both sides of the fixed plate 2 rotate in opposite directions, that is, the end of the support frame 3 in the horizontal state away from the base 1 rotates upward. At the same time, during the rotation of the output shaft of the third servo motor 36, the third sprocket 40 and the third chain 41 cooperate to drive the rotating rod 31 to rotate. During the rotation, the rotating rod 31 reels in the control rope 32, so that the control rope 32 pulls the end of the support frame 3 away from the base 1 upward, thereby facilitating the support frame 3 to rotate vertically. Since the seedling tube 4 is rotatably connected to the vertical rod 13, during the upward rotation of the end of the support frame 3 away from the base 1, since the seedling tube 4 is filled with nutrient soil, the seedling tube 4 is always vertically downward due to gravity. Therefore, when the support frame 3 rotates to a vertical state, the open end of the seedling tube 4 is still facing upward.

[0088] When the support frame 3 is in a vertical state, the second servo motor 25 and the first servo motor 18 are turned on. The output shaft of the first servo motor 18 drives the winding roller 6 to rotate through the cooperation of the first sprocket 19 and the first chain 20, and the winding roller 6 unfolds the protective plate 7. When the second servo motor 25 drives the rotating shaft 24 to rotate through the cooperation of the second sprocket 26 and the second chain 27, the rotating shaft 24 drives the lead screw 23 to rotate, thereby driving the connecting rod 21 to move upward through the lead screw 23, so that the connecting rod 21 drives the upper end of the protective plate 7 to move upward. When the upper surface of the connecting rod 21 contacts the upper surface of the top plate 9, a closed seedling box is formed between the top plate 9, the base 1, the fixed plate 2 and the protective plate 7, thereby isolating external light and facilitating the germination rate of photophobic seeds.

[0089] When the photophobic seeds germinate and need light, the staff starts the first servo motor 18 and the second servo motor 25. The first servo motor 18 drives the winding roller 6 to rotate in the opposite direction through the cooperation of the first sprocket 19 and the first chain 20, and the winding roller 6 reels the protective plate 7. The second servo motor 25 drives the rotating shaft 24 and the lead screw 23 to rotate in the opposite direction through the cooperation of the second sprocket 26 and the second chain 27, thereby driving the connecting rod 21 to move downward through the lead screw 23, so that the winding roller 6 can reel in the protective plate 7. When the lower surface of the connecting rod 21 contacts the upper surface of the base 1, The third servo motor 36 is started, and the output shaft on the third servo motor 36 drives the rotating rod 31 to rotate through the cooperation of the third sprocket 40 and the third chain 41, and the rotating rod 31 unfolds the control rope 32. At the same time, the third servo motor 36 drives the rotating shaft 38 to rotate through the cooperation of the first gear 37 and the second gear 39, driving the upper end of the vertical support frame 3 to rotate downward. When the support frames 3 on both sides of the fixed plate 2 rotate to a horizontal state, the multiple seedling tubes 4 on the support frames 3 are horizontally unfolded, thereby facilitating the lighting of the seedlings in the seedling tubes 4, promoting the photosynthesis of the seedlings, and facilitating the growth of the seedlings.

[0090] During the photosynthesis of the seedlings, when sunlight shines on the solar panel 11, the solar panel 11 converts the sunlight into electrical energy and stores it in the battery. At night and in rainy weather, the staff starts the first servo motor 18, the second servo motor 25 and the third servo motor 36 to horizontally store the multiple horizontally unfolded seedling tubes 4, and turn on the plant growth lamp 8 at the same time. Since the side walls relative to the two protective plates 7 are reflective layers, after the plant growth lamp 8 is turned on, the protective plate 7 reflects the light emitted by the plant growth lamp 8, thereby increasing the light brightness in the seedling box formed between the protective plate 7, the top plate 9, the base 1, and the fixed plate 2, thereby further promoting the growth of the seedlings. At the same time, in rainy weather, it also avoids the staff from carrying the seedlings, which brings convenience to the staff.

[0091] In rainy weather, rainwater flows downward through the inclined surface of the solar panel 11 to the strip rainwater collection groove 33, and then flows into the rainwater collection chamber 29 through the drainage hole 35, and at the same time flows downward into the water storage chamber 17 through the drainage pipe 34, the water storage chamber 48 and the connecting pipe at the bottom of the water storage chamber 48 for storage. When it is necessary to water the seedlings in the seedling tube 4, the water in the water storage chamber 48 flows into the through hole 42 through the port of the rotating shaft 38, and then flows into the rainwater collection chamber 29 through the drainage hole 35. 3 flows into the seedling tube 4, thereby watering the seedlings in the seedling tube 4. When the water in the seedling tube 4 penetrates into the water storage box 5 through the nutrient soil downward through the seepage hole 44, and the excess water in the nutrient soil accumulates in the water storage box 5, the gravity of the water storage box 5 increases. When the gravity sensor 47 senses the increase in the gravity of the water storage box 5, the gravity sensor 47 transmits information to the automatic control valve 45, and the automatic control valve 45 is closed, thereby avoiding excessive water accumulation in the seedling tube 4.

[0092] When the water in the water storage box 5 evaporates upward and enters the nutrient soil in the seedling tube 4, the gravity of the water storage box 5 is reduced. At this time, the gravity sensor 47 transmits information to the automatic control valve 45, and the automatic control valve 45 opens, so as to automatically water the seedlings in the seedling tube 4, reduce manpower and time, and effectively avoid water accumulation in the nutrient soil in the seedling tube 4, which is convenient for the growth of seedlings.

[0093] An electric control valve is installed in the connecting pipe at the bottom of the water storage chamber 48, and a water pump is fixedly connected to the bottom of the water storage chamber 17. The water outlet end of the water delivery pipe on the water pump passes through the top of the water storage chamber 17 and is connected to the water storage chamber 48, so that the water pump can transport the rainwater collected in the water storage chamber 17 upward to the water storage chamber 48. The water pump and the electric control valve are connected to the gravity sensor 47 through a signal. When the gravity sensor 47 senses that the gravity of the water storage box 5 is reduced, the water pump is turned on to transport the water in the water storage chamber 17 to the water storage chamber 48, and the electric control valve is in a closed state to prevent the water in the water storage chamber 48 from flowing back downward into the water storage chamber 17 through the connecting pipe. The water storage chamber 17 is connected to an external water delivery system such as a faucet through a pipe, so as to replenish the water in the water storage chamber 17.
