The top of the top cover body 51 is fixedly connected to a worm motor placement seat 52 on one side away from the feeding port 55, and the top of the worm motor placement seat 52 is fixedly connected to a worm motor 53, and the output end of the worm motor 53 is fixedly connected to a worm 54, and the outer wall of the worm 54 meshes with the gear 56, and the gear 5 6 is fixedly connected to a rotating rod 57, the bottom of the rotating rod 57 penetrates the inner wall of the culture column 44 and is fixedly connected to a stirring mechanism 58, the stirring mechanism 58 includes a stirring rotating rod 581, a plurality of L-shaped connecting rods 582 are fixedly connected to the outer wall of the stirring rotating rod 581 in a circular array, a bottom of the stirring rotating rod 581 is movably connected to a bottom rod connecting plate 583, a bottom of the bottom rod connecting plate 583 is fixedly connected to a bottom rod 584, the bottom of the bottom rod 584 is fixedly connected to the bottom of the inner wall of the culture column 44, a second gear 585 is fixedly connected to the top of the outer wall of the bottom rod 584, a plurality of L-shaped connecting rods 582 are movably connected to a stirring rod rotating rod 587 on one side away from the stirring rotating rod 581, and a third gear 586 is fixedly connected to the outer walls of the plurality of stirring rod rotating rods 587.The outer walls of the plurality of third gears 586 are all meshed with the outer wall of the second gear 585, the outer walls of the plurality of stirring rod rotating rods 587 on the side away from the third gear 586 are movably connected with the stirring rod outer limiting shaft 588, the outer walls of the stirring rod outer limiting shaft 588 are all fixedly connected with the outer limiting shaft connecting rod 589, the sides of the plurality of outer limiting shaft connecting rods 589 away from the stirring rod outer limiting shaft 588 are fixedly connected with the bottom rod sleeve shaft 5811, the inner wall of the bottom rod sleeve shaft 5811 is movably connected to the outer wall side of the bottom rod 584 away from the second gear 585, and the bottoms of the plurality of stirring rod rotating rods 587 are all fixedly connected with the stirring rod 5810;

[0033] When it is necessary to cultivate watermelon seeds, firstly, the watermelon seeds are placed in the cultivation pot 4610 and placed on the cultivation pot placement plate 463. Since the outer walls of the cultivation pot 4610 are opposite to the two groups of clamping plates 469 on both sides, the motor 465 drives the bidirectional screw rod 466 to rotate, thereby driving the two transmission shafts 467 to move relative to or opposite to each other along the direction of the screw rod, so that the two groups of clamping plates 469 can tightly clamp the cultivation pot 4610, thereby fixing the cultivation pot 4610 to prevent the cultivation pot 4610 from shifting or tipping over due to shaking or other factors during the cultivation process;

[0034] Subsequently, an appropriate amount of nutrient solution is injected into the culture column 44 through the feed port 55, and the nutrient solution flows in through the pipeline 3 to ensure the purity of the nutrient solution and avoid the adverse effects of impurities on the cultivation of watermelon seeds. At the same time, the nutrient solution will be sprayed by the atomizing nozzle 47 and evenly covered on the watermelon seeds in the cultivation basin 4610 to provide necessary nutrition and moisture;

[0035] During the cultivation process, the temperature is controlled as needed. The temperature in the culture column 44 can be adjusted by setting the temperature controller 49 to ensure that the watermelon seeds grow under the most suitable temperature conditions. The temperature controller 49 can be adjusted according to actual needs to meet the different temperature requirements of different varieties of watermelon seeds.

[0036] In addition, in order to better mix and stir the nutrient solution and ensure that the watermelon seeds can evenly absorb nutrients, the worm motor 53 starts to work, and the rotation of the worm 54 drives the gear 56 and the rotating rod 57 to rotate, thereby starting the stirring mechanism 58 to work, and the stirring rotating rod 581 drives the L-shaped connecting rod 582 and the stirring rod rotating rod 587 to rotate, and the stirring rod 5810 rotates accordingly to stir the nutrient solution in the culture column 44. At the same time, due to the meshing of the third gear 586 and the second gear 585, the stirring rod rotating rod 587 will also revolve around the bottom rod 584 while rotating, further enhancing the stirring effect;

[0037] Waste or unnecessary nutrient solution generated during the cultivation process can flow into the waste storage box 2 through the pipeline 3 for collection and treatment, so as to keep the cultivation environment clean and hygienic;

[0038] In addition, since the overall cylindrical design of the device is convenient for staff to observe and place watermelon seeds, the cylindrical structure is also conducive to reducing heat loss, maintaining a stable temperature in the culture column 44, and providing a more suitable growth environment for watermelon seeds.

[0039] like Figure 7 As shown, the telescopic baffle control mechanism 6 includes a telescopic baffle transmission frame 61, a second motor 62 is fixedly connected to the front bottom of the telescopic baffle transmission frame 61, a lifting block slot 63 is provided on the front side of the telescopic baffle transmission frame 61, a screw rod 65 is fixedly connected to the output end of the second motor 62, the top of the screw rod 65 is movably connected to the front top of the telescopic baffle transmission frame 61, a lifting block 66 is threadedly connected to the outer wall of the screw rod 65, a lifting block slider 67 is fixedly connected to the rear side of the lifting block 66, the outer wall of the lifting block slider 67 is slidably connected to the inner wall of the lifting block slot 63, a cylindrical telescopic baffle 68 is fixedly connected to the front side of the lifting block 66, the top of the cylindrical telescopic baffle 68 is fixedly connected to the bottom of the top plate 48, and the bottom outer wall of the cylindrical telescopic baffle 68 is fixedly connected to the front side of the lifting block 66;

[0040] When the culture column 44 needs to be opened or closed, the staff can drive the screw rod 65 to rotate by controlling the rotation of the second motor 62. Since the screw rod 65 is connected to the lifting block 66 by a thread, when the screw rod 65 rotates, the lifting block 66 will move up and down along the axial direction of the screw rod 65. At the same time, the lifting block slider 67 slides in the lifting block slide groove 63, ensuring the stability and guidance of the lifting block 66 during the lifting process.

[0041] As the lifting block 66 rises and falls, the cylindrical telescopic baffle 68 fixedly connected to its front side will also extend and retract upward or downward accordingly. When the cylindrical telescopic baffle 68 extends and retracts upward, it will gradually move away from the sealing groove 42 at the bottom of the culture column 44, thereby allowing the staff to put in or take out the culture basin 4610, as well as clean and maintain the interior. When the cylindrical telescopic baffle 68 moves downward, it will completely close the sealing groove 42, ensuring the temperature inside the culture column 44 is stable, and preventing external impurities from entering and affecting the cultivation of watermelon seeds.

[0042] Working principle of the present invention: When it is necessary to cultivate watermelon seeds, firstly, the watermelon seeds are placed in the cultivation pot 4610 and placed on the cultivation pot placement plate 463. Since the two sides of the outer wall of the cultivation pot 4610 are respectively opposite to the two groups of clamping plates 469, the motor 465 drives the bidirectional screw rod 466 to rotate, thereby driving the two transmission shafts 467 to move relative to or opposite to each other along the direction of the screw rod, so that the two groups of clamping plates 469 can tightly clamp the cultivation pot 4610, thereby fixing the cultivation pot 4610, and preventing the cultivation pot 4610 from shaking or other factors during the cultivation process. 10 is shifted or poured, and then, an appropriate amount of nutrient solution is injected into the culture column 44 through the feed port 55. The nutrient solution flows in through the pipeline 3 to ensure the purity of the nutrient solution and avoid the adverse effects of impurities on the cultivation of watermelon seeds. At the same time, the nutrient solution will be sprayed by the atomizing nozzle 47 and evenly covered on the watermelon seeds in the cultivation basin 4610 to provide necessary nutrition and moisture. During the cultivation process, the temperature is controlled as needed. The temperature in the culture column 44 can be adjusted by setting the thermostat 49 to ensure that the watermelon seeds grow under the most suitable temperature conditions. The thermostat 4 9 can be adjusted according to actual needs to meet the different temperature requirements of different varieties of watermelon seeds. In addition, in order to better mix and stir the nutrient solution and ensure that the watermelon seeds can evenly absorb nutrients, the worm motor 53 starts to work, and the rotation of the worm 54 drives the gear 56 and the rotating rod 57 to rotate, thereby starting the stirring mechanism 58. The stirring rotating rod 581 drives the L-shaped connecting rod 582 and the stirring rod rotating rod 587 to rotate, and the stirring rod 5810 rotates accordingly to stir the nutrient solution in the culture column 44. At the same time, due to the third gear 586 and the second gear 5 85 are meshed, the stirring rod 587 will revolve around the bottom rod 584 while rotating, further enhancing the stirring effect. Waste or unnecessary nutrient solution generated during the cultivation process can flow into the waste storage box 2 through the pipeline 3 for collection and treatment, keeping the cultivation environment clean and hygienic. In addition, since the device is designed as a whole in a cylindrical shape, it is convenient for staff to observe and place watermelon seeds. At the same time, the cylindrical structure is also conducive to reducing heat loss, maintaining a stable temperature in the culture column 44, and providing a more suitable growth environment for watermelon seeds.

[0043] When it is necessary to open or close the culture column 44, the staff can drive the screw rod 65 to rotate by controlling the rotation of the second motor 62. Since the screw rod 65 is connected to the lifting block 66 by a threaded connection, when the screw rod 65 rotates, the lifting block 66 will move up and down along the axial direction of the screw rod 65. At the same time, the lifting block slider 67 slides in the lifting block slide groove 63, ensuring the stability and guidance of the lifting block 66 during the lifting process. As the lifting block 66 rises and falls, the cylindrical telescopic baffle 68 fixedly connected to its front side will also be extended and retracted upward or downward accordingly. When the cylindrical telescopic baffle 68 is extended and retracted upward, it will gradually move away from the sealing groove 42 at the bottom of the culture column 44, thereby allowing the staff to put in or take out the culture basin 4610, as well as clean and maintain the interior. When the cylindrical telescopic baffle 68 moves downward, it will completely close the sealing groove 42, ensuring the temperature inside the culture column 44 is stable, and preventing external impurities from entering and affecting the cultivation of watermelon seeds.
