[0019] 1. The present invention provides a placement component, and when the planting basket is installed on the mounting frame, the developed seeds are placed in the planting cotton, and the planting cotton with seeds is placed in the planting basket at the same time. By pulling the extrusion plate downward, the extrusion plate drives the guide rod through the extrusion rod to make the contact mechanism slide upward in the planting basket, so that the planting cotton with seeds is placed in the contact mechanism, avoiding the need to use tools to pound the planting cotton into the planting basket when placing the planting cotton in the planting basket because the planting cotton itself is relatively soft.

[0022] 4. The present invention provides a cleaning component. When the water storage box needs to be cleaned, the electric hydraulic cylinder is opened, and the output end of the electric hydraulic cylinder drives the sliding block to move in the sliding groove, so that the blocking block is separated from the inner wall of the drain tank, so that the nutrient solution in the water storage box can be discharged. At the same time, the movement of the sliding block can drive the moving rod to move in the water storage box, so that the connecting shaft drives the rubber block to contact and rotate with the bottom of the inner cavity of the water storage box, so that the rubber block contacts and cleans the bottom of the inner cavity of the water storage box. At the same time, the scraper moves against the water storage box, so that the nutrient solution attached to the bottom of the inner cavity of the water storage box can be removed. The impurities on the water box can be scraped off. At the same time, since the nutrient solution in the water storage box is in contact with the rhizomes of the seedlings for a long time, a large amount of rhizome debris will remain in the water storage box. By providing a triangular plate on the side of the blocking block close to the scraper, when the blocking block is moved in the water storage box for cleaning, the triangular shape of the triangular plate allows the rhizomes to move to both sides of the triangular plate when the triangular plate contacts the rhizomes remaining in the water storage box. At the same time, by providing a notch at the bottom of the triangular plate, the rhizomes guided into the notch through the triangular plate can be collected and limited, thereby avoiding a large amount of rhizome impurities remaining in the water storage box when the water storage box is cleaned.

[0043] like Figure 7-Figure 9 The present invention shows a hydroponic seedling device suitable for small seeds, based on the first embodiment;

[0044] The cleaning component 6 includes an electric hydraulic cylinder 61 and a sliding groove 62. The electric hydraulic cylinder 61 is arranged on one side of the water storage tank 31 close to the water drain tank 4.

At the same time, since the nutrient solution in the water storage box 1 is in contact with the rhizomes of the seedlings for a long time, a large amount of rhizomes will remain in the water storage box 1. A triangular plate 636 is provided on one side of 35, so that when the blocking block 632 is moved and cleaned in the water storage box 1, the triangular shape of the triangular plate 636 allows the rhizomes remaining in the water storage box 1 to move to both sides of the triangular plate 636 when the triangular plate 636 contacts the rhizomes, and at the same time, a notch 637 is provided at the bottom of the triangular plate 636, so that the rhizomes guided into the notch 637 through the triangular plate 636 can be collected and limited, thereby avoiding a large amount of rhizome impurities remaining in the water storage box 1 when the water storage box 1 is cleaned.

[0046] A hydroponic seedling method suitable for small seeds comprises the following steps:

[0047] S1: placing germinated seeds of small seeds in the placing component 5, and placing the placing component 5 on the mounting frame 2;

[0048] S2: Pour the nutritional powder into the connecting component 3, and mix and stir the nutritional powder and the water in the connecting component 3 through the connecting component 3;

[0049] S3: The nutrient solution after mixing in the connecting component 3 is transported to the water storage box 1 by opening the water pipe 7;

[0050] S4: After the seedling raising work is completed, the cleaning component 6 moves in the water storage box 1 to clean and discharge the inside of the water storage box 1.

[0051] The specific workflow is as follows:

[0052] During operation, the placing component 5 is placed on the mounting frame 2, and the germinated seeds are placed in the placing component 5. At the same time, water and nutrient powder are added to the connecting component 3, and the nutrient powder and water are mixed through the connecting component 3. At the same time, the mixed nutrient solution in the connecting component 3 flows into the water storage box 1 by opening the water pipe 7. At the same time, the mounting frame 2 is placed in the water storage box 1, so as to carry out hydroponic seedling cultivation. When the seeds are fully grown and picked, the inside of the water storage box 1 can be cleaned through the cleaning component 6.

[0053] When the planting basket 51 is installed on the mounting frame 2, the developed seeds are placed in the planting cotton, and the planting cotton with seeds is placed in the planting basket 51 at the same time. By pulling the squeezing plate 53 downward, the squeezing plate 53 drives the guide rod 56 through the squeezing rod 52 to make the contact mechanism 57 slide upward in the planting basket 51, so that the planting cotton with seeds is placed in the contact mechanism 57, avoiding the need to use tools to tamp the planting cotton into the planting basket 51 when placing the planting cotton in the planting basket 51 because the planting cotton itself is relatively soft;

[0054] The squeezing plate 53 drives the guide rod 56 to move the contact plate 571 upwards through the squeezing rod 52, so that the planting cotton is manually placed between the four contact plates 571 and the arc plate 574, so that the contact plate 571 is against the sponge, and at the same time, by evenly opening the slide grooves 572 on the contact plate 571, it is avoided that the squeezing force between the contact block 573 and the planting cotton is too large, thereby damaging the germinated seeds in the planting cotton. After the planting cotton is placed, by loosening the squeezing plate 53, the squeezing plate 53 is driven to move downwards by the stretching and resetting action of the first spring 54, so that the squeezing rod 52 drives the contact plate 571 to move downwards through the guide rod 56, so that the contact block 573 drives the planting cotton with seeds to contact the nutrient solution in the water storage tank 31, so that the germinated seeds are hydroponically cultivated;

[0055] The nutrient powder is added into the water tank 31, and the motor 32 is turned on. The output end of the motor 32 drives the stirring shaft 33 to rotate in the inner cavity of the water tank 31, so that the stirring shaft 33 drives the stirring blade 34 to fully mix the nutrient powder and water in the water tank 31. At the same time, the stirring shaft 33 drives the stirring blade 34 to rotate, and the rotating mechanism 35 rotates on the stirring blade 34.

[0056] When the stirring shaft 33 drives the stirring blade 34 to rotate, the centrifugal force generated by the rotation of the stirring shaft 33 causes the slider 353 to move on the slide rod 352. At the same time, the stirring shaft 33 continues to rotate in the water storage tank 31, so that the rotating plate 355 drives the curved hook 356 to rotate on the rotating rod 354, so that the curved hook 356 can hit the agglomerated substances in the nutrient powder, thereby accelerating the mixing speed of the nutrient powder and water, and preventing the agglomerated substances in the nutrient powder from being melted and mixed with water for a long time.

[0057] When it is necessary to clean the water box 1, the electric hydraulic cylinder 61 is opened, and the output end of the electric hydraulic cylinder 61 drives the sliding block 638 to move in the sliding groove 62, so that the blocking block 632 is separated from the inner wall of the drain tank 4, so that the nutrient solution in the water box 1 can be discharged. At the same time, when the sliding block 638 moves, it can drive the moving rod 631 to move in the water box 1, so that the connecting shaft 633 drives the rubber block 634 to contact and rotate with the bottom of the inner cavity of the water box 1, so that the rubber block 634 contacts and cleans the bottom of the inner cavity of the water box 1. At the same time, the scraper 635 moves against the water box 1, so that impurities attached to the bottom of the inner cavity of the water box 1 can be scraped off. At the same time, since the nutrient solution in the water storage box 1 is in contact with the rhizomes of the seedlings for a long time, a large amount of rhizome debris will remain in the water storage box 1. By providing a triangular plate 636 on the side of the blocking block 632 close to the scraper 635, when the blocking block 632 is moved in the water storage box 1 for cleaning, the triangular shape of the triangular plate 636 allows the rhizomes to move to both sides of the triangular plate 636 when the triangular plate 636 contacts the rhizomes remaining in the water storage box 1. At the same time, by providing a notch 637 at the bottom of the triangular plate 636, the rhizomes guided through the triangular plate 636 and entering the notch 637 can be collected and limited, thereby avoiding a large amount of rhizome impurities remaining in the water storage box 1 when the water storage box 1 is cleaned.
