Description

Technical Field

[0001] This utility model relates to the technical field of hydroponic devices for melon seedlings, specifically a hydroponic device for muskmelon seedlings. Background Technology

[0002] Melon seedlings are the seedlings that grow to a certain stage after the melon seeds germinate. This is an important stage in the melon planting process. During the initial growth of melon seedlings, they need to be cultivated to ensure stable and rapid growth and improve the survival rate in the later stages.

[0003] In the current cultivation process, melon seedlings are usually grown hydroponically, with the roots immersed in a nutrient solution to ensure sufficient absorption and stable growth. However, during actual cultivation, as the seedlings grow and absorb nutrients, and due to temperature variations, the nutrient solution level in the cultivation box will drop. Since staff cannot constantly monitor the cultivation box, it's easy for them to fail to replenish the nutrient solution in time when the level drops, thus affecting the cultivation effect and resulting in poor actual performance. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a hydroponic device for melon seedlings, which solves the problem that during the cultivation process, as the seedlings continuously absorb nutrients and evaporate due to temperature changes, the liquid level in the cultivation box drops, making it impossible for staff to monitor the liquid level in the cultivation box at any time, resulting in nutrient deficiency in the seedlings and affecting their normal growth and cultivation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A cultivation box is included, with a cultivation plate movably connected inside. Several evenly distributed cultivation grooves are formed on the upper surface of the cultivation plate. A through groove is formed on one side of the cultivation box, and a water box is provided at the through groove. The water box is fixedly connected to the cultivation box. An adjusting block is slidably connected inside the water box. A liquid level sensor is fixedly connected to the upper surface of the adjusting block, and a liquid level probe is fixedly connected to the lower surface of the liquid level sensor. A positioning frame is fixedly connected to the lower surface of the water box. A forward and reverse motor is fixedly connected to the upper surface of the positioning frame. A screw rod is connected to the output end of the forward and reverse motor. A connecting frame is screwed onto the outer wall of the screw rod. A connecting rod is fixedly connected to the connecting frame. A limiting block is fixedly connected to the end of the connecting rod away from the connecting frame. The limiting block is slidably connected to the water box and fixedly connected to the adjusting block. A limiting groove adapted to the limiting block is formed on one side of the water box.

[0006] The beneficial effects of this utility model are as follows: the operation of the forward and reverse motors causes the screw rod to be screwed to the connecting frame, thereby allowing the connecting frame, along with the connecting rod and the limiting block, to move flexibly up and down. This, in turn, causes the limiting block, along with the liquid level sensor and liquid level probe on the connecting block, to move flexibly up and down, allowing the liquid level probe to move to the appropriate position. In conjunction with the use of the liquid level sensor and liquid level probe, the liquid level of the nutrient solution in the cultivation box is detected, ensuring that the nutrient solution is always kept at an appropriate level, thereby providing sufficient nutrients for the seedlings and ensuring their stable growth.

[0007] In order to support the cultivation board;

[0008] As a further improvement to the above technical solution: a limiting frame is fixedly connected to the inner wall of the cultivation box, and the limiting frame is located on the lower end face of the cultivation plate;

[0009] The beneficial effects of this improvement are: by using a limiting frame, the cultivation plate can be limited and supported, ensuring sufficient stability during use.

[0010] In order to achieve docking and fixation of the cultivation board;

[0011] As a further improvement to the above technical solution: docking grooves are provided at the four corners of the limiting frame, and docking posts are movably connected in the docking grooves, and the docking posts are fixedly connected to the cultivation plate;

[0012] The beneficial effects of this improvement are: by connecting the docking column and the docking groove, the cultivation plate can be made stable enough during use, without tilting or shaking, thus ensuring that the cultivated seedlings can grow stably.

[0013] In order to achieve the delivery of nutrient solution;

[0014] As a further improvement to the above technical solution: a water inlet trough is provided on one side of the cultivation box, a water inlet pipe is provided at the water inlet trough, the water inlet pipe is fixedly connected to the cultivation box, a water pump is fixedly connected to the end of the water inlet pipe away from the cultivation box, and a connecting pipe is fixedly connected to the end of the water pump away from the water inlet pipe.

[0015] The beneficial effects of this improvement are: by using a water pump, external nutrient solution can be connected through a connecting pipe, and the nutrient solution can be delivered through the water inlet pipe and the nutrient solution can be delivered into the water inlet tank cultivation box.

[0016] In order to discharge excess nutrient solution;

[0017] As a further improvement to the above technical solution: a drain pipe is fixedly connected to the side of the cultivation box away from the water inlet pipe, and a control valve is fixedly connected to the drain pipe;

[0018] The beneficial effects of this improvement are: by using the control valve, the opening and closing of the drain pipe can be flexibly controlled, and in conjunction with the use of the drain pipe, excess nutrient solution in the cultivation tank can be discharged, ensuring that the liquid level of nutrient solution in the cultivation box is appropriate.

[0019] In order to allow the roots of the seedlings to extend downwards smoothly;

[0020] As a further improvement to the above technical solution: several evenly distributed water-permeable holes are provided on the bottom wall of the cultivation tank;

[0021] The beneficial effects of this improvement are: the use of permeable holes allows the nutrient solution to enter the cultivation tank smoothly, while also facilitating the downward extension of the seedling roots, ensuring sufficient contact between the roots and the nutrient solution.

[0022] In order to enable operation of the cultivation board;

[0023] As a further improvement to the above technical solution: two symmetrical handles are fixedly connected to the upper surface of the cultivation plate;

[0024] The beneficial effects of this improvement are: the use of handles allows for the installation and lifting of the cultivation plate, making it easier for staff to operate.

[0025] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

A through groove 13 is opened on one side of the cultivation box 1, and a water box 14 is provided at the through groove 13. The water box 14 is fixedly connected to the cultivation box 1, and an adjusting block 15 is slidably connected inside the water box 14. A liquid level sensor 16 is fixedly connected to the upper surface of the adjusting block 15, and the lower surface of the liquid level sensor 16... A liquid level probe 17 is fixedly connected. A positioning frame 18 is fixedly connected to the lower end face of the water box 14. A forward and reverse motor 19 is fixedly connected to the upper end face of the positioning frame 18. A screw rod 20 is connected to the output end of the forward and reverse motor 19. A connecting frame 21 is screwed onto the outer wall of the screw rod 20. A connecting rod 22 is fixedly connected to the connecting frame 21. A limit block 23 is fixedly connected to the end of the connecting rod 22 away from the connecting frame 21. The limit block 23 is slidably connected to the water box 14. The limit block 23 is fixedly connected to the adjusting block 15. A limit groove 24 adapted to the limit block 23 is opened on one side of the water box 14. The limit groove 24 can limit the limit block 23, ensuring the stability of the limit block 23. Under the action of the forward and reverse motor 19, the screw rod 20 and the connecting frame 21 are screwed together, thereby connecting... The frame 21, along with the connecting rod 22 and the limiting block 23, allows for flexible lifting and lowering adjustments, moving the liquid level probe 17 to a suitable position. Through the use of the liquid level sensor 16 and the liquid level probe 17, the liquid level of the nutrient solution in the cultivation box 1 is monitored. A limiting frame 31 is fixedly connected to the inner wall of the cultivation box 1, located on the lower end face of the cultivation plate 11. The limiting frame 31 supports the cultivation plate 11. Each of the four corners of the limiting frame 31 has a docking groove 41, within which a docking post 42 is movably connected. The docking post 42 is fixedly connected to the cultivation plate 11. With the use of the four docking grooves 41 and their corresponding docking posts 42, a stable connection can be established between the cultivation plate 11 and the limiting frame 31, ensuring sufficient nutrient solution for the cultivation plate 11 during use. The cultivation box 1 is stable. A water inlet trough 51 is provided on one side, with a water inlet pipe 52 fixedly connected to the cultivation box 1. A water pump 53 is fixedly connected to the end of the water inlet pipe 52 furthest from the cultivation box 1, and a connecting pipe 54 is fixedly connected to the end of the water pump 53 furthest from the water inlet pipe 52. Under the action of the water pump 53, the connecting pipe 54 connects to the external nutrient solution, thus delivering the nutrient solution into the cultivation box 1. A drain pipe 61 is fixedly connected to the side of the cultivation box 1 furthest from the water inlet pipe 52, and a control valve 62 is fixedly connected to the drain pipe 61. The control valve 62 controls the opening and closing of the drain pipe 61, and the drain pipe 61 allows for the collection and discharge of excess nutrient solution from the cultivation box 1.Two symmetrical handles 81 are fixedly connected to the upper surface of the culture plate 11. The use of the two handles 81 facilitates the handling of the culture plate 11 by workers, and makes it convenient to install or disassemble it.

[0037] The working principle and usage process of this utility model are as follows: First, the four corner joints 42 at the lower end face of the cultivation plate 11 are aligned with the joint grooves 41 on the limiting frame 31 to ensure sufficient stability of the cultivation plate 11. Then, the seeds to be cultivated are placed in the cultivation trough 12. With the use of the permeable holes 71, the seeds are allowed to fully contact the nutrient solution, enabling germination and root development. The roots of the seedlings extend downwards through the permeable holes 71. During use, the operation of the forward and reverse motors 19 causes the spiral rod 20 to connect with the connecting frame 21. The connecting frame 21, along with the connecting rod 22 and the limiting block 23, is screwed together, allowing the connecting frame 21 to be raised and lowered. This, in turn, causes the limiting block 23 to be raised and lowered along with the liquid level sensor 16 and the liquid level probe 17 on the connecting block. The liquid level probe 17 is then moved to a suitable position to monitor the nutrient solution level in the cultivation box 1. When the liquid level is low, the water pump 53 is used to pump the nutrient solution into the cultivation box 1 through the connecting pipe 54 and the inlet pipe 52, thus completing the entire process of using the melon seedling hydroponic device.
