Description

Technical Field

[0001] The present application relates to the technical field of plant cultivation, and specifically discloses a hydroponic device for plants. Background Art

[0002] Plant hydroponics refers to a cultivation method that uses nutrient solution to provide water, nutrients and oxygen to make plants grow in water. Common hydroponic plants include ornamental foliage plants such as green radish, spider plant, ivy, syngonium, and monstera. In addition, vegetables such as lettuce, kale, and spinach can also be grown. These vegetables usually grow quickly and are easy to manage in a hydroponic system.

[0003] When hydroponically growing plants, not only the lighting, temperature and humidity of the plant cultivation environment need to be strictly controlled, but also the hydroponic container, the quality of the culture solution in the hydroponic container, and the liquid level of the culture solution need to be strictly controlled. For example, a lower liquid level may be required in the seedling stage of the plant to promote the development of the root system; while in the mature stage, a higher liquid level may be required to meet the needs of its transpiration, and too high a liquid level may cause the plant to be immersed in water for a long time, which is easy to cause root diseases. By controlling the liquid level, the environment for the growth of pathogens can be reduced and the risk of disease can be reduced.

[0004] At present, most of the liquid level of the nutrient solution in the hydroponic container is still controlled by regular manual detection, and drainage and watering operations are performed according to actual needs. Some hydroponic equipment is also equipped with an automatic water supply system, the main principle of which is to use ultrasonic and other equipment to detect the water level, and to control the opening or closing of the valve through a controller to adjust the liquid level in the container. However, the automatic water supply system not only has many equipment and high cost, but also is difficult to debug and has poor stability. Of course, some hydroponic equipment automatically controls the water supply to the container through the action of buoyancy blocks. The principle is mainly to use buoyancy blocks to automatically control the water supply to the container. The buoyancy block floats on the liquid surface, and the rise or fall of the liquid level will drive the buoyancy block to rise and fall, thereby controlling the connection or disconnection of the pipeline. However, this water supply method is only applicable to small hydroponic containers. When the hydroponic container is large, the required amount of water is large, and the pressure of the water above on the buoyancy block is large, and the buoyancy demand of the buoyancy block is also large, which makes the overall structure of the buoyancy block larger, resulting in the occupation of the space used for cultivating plants. In summary, the current control of the liquid level height in the hydroponic equipment is relatively complicated and cumbersome, and the cost is relatively high. Therefore, in view of this, the inventor provides a hydroponic equipment for plants to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that traditional hydroponic equipment uses manual monitoring, ultrasonic monitoring or buoyancy adjustment to control the liquid level of nutrient solution for hydroponic plants, and the control process is complicated and cumbersome, and the cost is high.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the present invention provides a hydroponic equipment for plants, including a hydroponic box and a feeding assembly arranged on the side wall of the hydroponic box and used to supply nutrient solution into the hydroponic box, the feeding assembly includes a sealing cylinder arranged on the side wall of the hydroponic box, a feeding pipe arranged on the outer top of the sealing cylinder and capable of passing nutrient solution into the sealing cylinder, a feeding pipe arranged between the bottom of the sealing cylinder and the bottom of the hydroponic box, and a pressure-stabilizing pipe arranged on the top of the sealing cylinder, the end of the pressure-stabilizing pipe extends into the hydroponic box and is level with the liquid level required for plant hydroponics, and an air storage chamber connected to the pressure-stabilizing pipe is formed between the nutrient solution in the sealing cylinder and the inner top of the sealing cylinder.

[0007] The principles and effects of this basic solution are:

[0008] Compared with the prior art, the present invention provides a sealing cylinder, a feeding pipe and a pressure-stabilizing pipe. When the liquid level of the nutrient solution in the culture box is lower than the end of the pressure-stabilizing pipe, the pressure-stabilizing pipe is connected to the external air, so that the nutrient solution enters the culture box from the sealing cylinder through the feeding pipe. When the liquid level of the nutrient solution in the culture box is level with the end of the pressure-stabilizing pipe, the nutrient solution seals the end of the pressure-stabilizing pipe, and a closed environment is formed in the sealing cylinder. The air pressure prevents the nutrient solution in the sealing cylinder from flowing out, so that the liquid level in the culture box is always at the liquid level required for plant hydroponics. This improves the growth quality of plants, saves resources and enhances the ornamental value, and solves the problem that the traditional hydroponic equipment uses manual monitoring, ultrasonic monitoring or buoyancy adjustment to control the liquid level of the nutrient solution of hydroponic plants, and the control process is complicated and cumbersome, and the cost is high.

[0009] Furthermore, it also includes a plurality of drainage pipes arranged in the hydroponic box, the top of the drainage pipe is located above the end of the pressure-stabilizing pipe in the hydroponic box, and the bottom of the drainage pipe passes through the bottom of the side wall of the hydroponic box. The drainage pipe is arranged to discharge the excess nutrient solution in the culture box to avoid the problem that the liquid level is too high and the plant roots are partially submerged, causing the plant to be short of oxygen and affecting the normal growth of the plant.

[0010] Furthermore, a drainage groove is provided in the hydroponic box, the end of the pressure-stabilizing pipe passes through the drainage groove from top to bottom and is flush with the bottom of the drainage groove, and the end of the drainage pipe passes through the drainage groove from bottom to top and is connected to the inside of the drainage groove. With this arrangement, when the liquid level of the nutrient solution is too high, it is discharged from the drainage groove, and the drainage groove also plays a role in fixing the pressure-stabilizing pipe and the drainage pipe.

[0011] Furthermore, the two sides of the hydroponic box are respectively threadedly connected with a rotating handle, and the bottom of the rotating handle is rotatably connected to the drainage groove. Through this arrangement, the height of the pressure-stabilizing pipe and the drainage pipe can be adjusted according to the growth needs of the plants in different cycles, that is, the liquid level of the nutrient solution in the culture box can be adjusted, and the synchronous adjustment of the pressure-stabilizing pipe and the drainage pipe can be achieved at the same time.

[0012] Furthermore, a separation cylinder is provided between the feed pipe and the sealing cylinder, a through hole is provided between the top of the sealing cylinder and the bottom of the separation cylinder, and a sealing plate is rotatably connected in the sealing cylinder to seal the through hole. The provision of the separation cylinder facilitates the passage of the nutrient solution into the sealing cylinder, and the provision of the sealing plate enables the sealing cylinder to maintain a sealed environment.

[0013] Furthermore, the top of the feed pipe extends into the sealing cylinder and communicates with the inner bottom surface of the sealing cylinder, and a roller is provided at the bottom of the sealing cylinder, which is driven to rotate by the sealing plate and can seal the top of the feed pipe. The connection and disconnection between the sealing cylinder and the feed pipe are controlled by the roller, so that when the nutrient solution enters the sealing cylinder from the separation cylinder, the sealing cylinder and the feed pipe are separated by the roller, and the nutrient solution does not enter the incubator, so as to avoid the pressure balance in the sealing cylinder being destroyed when the nutrient solution is added to the sealing cylinder, resulting in a large amount of nutrient solution flowing into the incubator.

[0014] Furthermore, the sealing cylinder is rotatably connected with an adjustment shaft, the adjustment shaft is provided with a torsion spring, one end of the sealing plate is connected with the adjustment shaft, the adjustment shaft is provided with a lever, the roller is provided with a sleeve rod, the sleeve rod is provided with a slide groove, and the lever is provided with a slider slidably connected to the slide groove. This arrangement enables the sealing cylinder to be supplemented with nutrient solution when the sealing cylinder is rotated, driving the adjustment shaft to rotate, and then driving the lever to rotate, and then driving the sleeve rod and the roller to rotate through the matching relationship between the slider and the slide groove, thereby isolating the sealing cylinder from the feed pipe.

[0015] Furthermore, the bottom of the sealing cylinder is provided with an arc surface, the rotating roller is provided with a sealing roller adapted to the arc surface, and the sealing roller is provided with a plurality of liquid conducting grooves that can connect the sealing cylinder with the top of the feed pipe. This arrangement enables the liquid conducting grooves on the sealing roller to connect the sealing cylinder with the feed pipe, and the sealing roller can separate the sealing cylinder from the feed pipe after rotation.

[0016] Furthermore, an air guide cavity is provided in the sealing plate, an air guide hole is provided at the bottom of the sealing plate to connect the air guide cavity with the air storage cavity, and the top of the pressure stabilizing pipe is connected with the air guide cavity. This arrangement can prevent the nutrient solution from entering the pressure stabilizing pipe and destroying the pressure balance in the sealing cylinder.

[0017] Furthermore, a buoyancy ball is provided at the bottom of the sealing plate, so that when the liquid level in the sealing cylinder is too high, the buoyancy of the buoyancy ball can drive the sealing plate to rotate upward, thereby isolating the sealing cylinder from the separation cylinder and preventing the nutrient solution from entering the air guide cavity of the sealing plate.

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0028] A hydroponic device for plants, for example Figure 1 and Figure 2 As shown: it includes a hydroponic box 1 and a feeding assembly arranged on the side wall of the hydroponic box 1 and used for supplying nutrient solution into the hydroponic box 1.

The feeding assembly includes a fixing frame 3 arranged on the side wall of the hydroponic box 1, a sealing cylinder 4 arranged on the fixing frame 3, a separating cylinder 6 arranged on the top of the sealing cylinder 4, a feeding pipe 5 arranged on the top of the separating cylinder 6 and capable of passing nutrient solution into the sealing cylinder 4, a feeding pipe 7 arranged between the bottom of the sealing cylinder 4 and the bottom of the hydroponic box 1, and a pressure-stabilizing pipe 10 arranged on the top of the sealing cylinder 4.

[0029] like Figure 2 and Figure 3 As shown, a drainage trough 12 is provided in the incubator, which is level with the liquid level required for hydroponics of plants. To meet the different liquid level requirements of plants in different growth cycles, two ear seats 13 are symmetrically provided on the two side walls of the incubator. The ear seats 13 are respectively threadedly connected to a rotating handle 14. The inner bottom surface of the drainage trough 12 is provided with a rotating sleeve 15 rotatably connected to the bottom of the rotating handle 14. The bottom of the rotating handle 14 is provided with a protrusion located below the rotating sleeve 15 to prevent the rotating handle 14 from being separated from the rotating sleeve 15. By rotating the rotating handle 14, the drainage trough 12 can be driven to rise and fall.

[0030] like Figure 2 and Figure 4 As shown, the end of the pressure-stabilizing pipe 10 passes through the drainage groove 12 from top to bottom and is flush with the bottom of the drainage groove 12. Similarly, a drainage pipe 11 is provided in the hydroponic box 1. The end of the drainage pipe 11 passes through the drainage groove 12 from bottom to top and is connected to the inside of the drainage groove 12. The bottom of the drainage pipe 11 passes through the bottom of the side wall of the hydroponic box 1 and is connected to the drainage main pipe 8.

[0031] like Figure 5As shown, adjusting boxes 9 are respectively provided at both ends of the sealing cylinder 4, and adjusting shafts 16 and rollers 17 are rotatably connected between the adjusting boxes 9 on both sides, and torsion springs 20 are respectively provided at both ends of the adjusting shaft 16, a lever 18 is provided on the adjusting shaft 16, a sleeve rod 19 is provided on the roller 17, a slide groove 22 is provided on the sleeve rod 19, and a slider 21 slidably connected in the slide groove 22 is provided on the lever 18, so that when the adjusting shaft 16 rotates, the lever 18 is driven to rotate, and then the sleeve rod 19 and the roller 17 are driven to rotate through the matching relationship between the slider 21 and the slide groove 22.

[0032] like Figure 6 As shown, the adjusting shaft 16 and the rotating roller 17 pass through the sealing cylinder 4, and a through hole communicating with each other is provided between the top of the sealing cylinder 4 and the bottom of the dividing cylinder, and an arc-shaped sealing plate 24 that can seal the through hole is provided on the adjusting shaft 16; the top of the feed pipe 7 extends into the sealing cylinder 4 and communicates with the inner bottom surface of the sealing cylinder 4, and an arc-shaped surface is provided at the bottom of the sealing cylinder 4. The rotating roller 17 is located on the wall surface inside the sealing cylinder 4 and is provided with a sealing roller 23 adapted to the arc-shaped surface, and the sealing roller 23 is provided with a plurality of liquid conducting grooves that can conduct the sealing cylinder 4 with the top of the feed pipe 7, and the liquid conducting grooves on the sealing roller 23 can conduct the sealing cylinder 4 with the feed pipe 7, and the sealing roller 23 can separate the sealing cylinder 4 from the feed pipe 7 after rotation.

[0033] like Figure 6 and Figure 7 As shown, an air guide cavity is provided in the sealing plate 24, and an air guide hole connecting the air guide cavity with the inside of the sealing tube 4 is provided at the bottom of the sealing plate 24. The top of the pressure-stabilizing pipe 10 is connected to the air guide cavity, and a buoyancy ball 25 is provided at the bottom of the sealing plate 24. When the liquid level in the sealing tube 4 is too high, the buoyancy of the buoyancy ball 25 can drive the sealing plate 24 to rotate upward, thereby isolating the sealing tube 4 from the separation tube 6 to prevent the nutrient solution from entering the air guide cavity of the sealing plate 24, so that an air storage cavity connected to the pressure-stabilizing pipe 10 is formed between the nutrient solution in the sealing tube 4 and the inner top of the sealed tube 4, and a pressure gauge is provided on the air storage cavity to detect the air pressure value to prevent the air pressure in the air storage cavity from being too high.

[0034] In this embodiment, the liquid level in the sealing cylinder 4 needs to be higher than the liquid level required for plant hydroponics. Of course, the sealing cylinder 4 can be structured in a manner that the entire sealing cylinder 4 is higher than the liquid level required for plant hydroponics to ensure that the nutrient solution in the sealing cylinder 4 can flow into the incubator. When the nutrient solution level in the incubator is lower than the end of the pressure-stabilizing pipe 10, the pressure-stabilizing pipe 10 is connected to the outside air, so that the nutrient solution enters the incubator from the sealing cylinder 4 through the feed pipe 7, and when the nutrient solution level in the incubator is level with the end of the pressure-stabilizing pipe 10, the nutrient solution seals the end of the pressure-stabilizing pipe 10, and a closed environment is formed in the sealing cylinder 4. The air pressure prevents the nutrient solution in the sealing cylinder 4 from flowing out, so that the liquid level in the incubator is always at the liquid level required for plant hydroponics. When the sealing cylinder 4 is supplemented with nutrient solution, the liquid pump on the feed pipe 5 pumps the nutrient solution into the sealing chamber. The impact of the nutrient solution causes the sealing plate 24 to rotate. At the same time, the rotation of the sealing plate 24 drives the adjusting shaft 16 to rotate, and then drives the lever 18 to rotate. Through the cooperation between the slider 21 and the slide groove 22, the sleeve rod 19 and the roller 17 are driven to rotate, thereby isolating the sealing cylinder 4 from the feed pipe 7, avoiding the pressure balance in the sealing cylinder 4 being destroyed when the nutrient solution is supplemented into the sealing cylinder 4, resulting in a large amount of nutrient solution pouring into the incubator.

[0035] Compared with the prior art, the present invention can ensure that the liquid level in the incubator is always at the liquid level required for hydroponic plants, thereby improving the growth quality of plants, saving resources and enhancing the ornamental value, and solving the problem that the traditional hydroponic equipment uses manual monitoring, ultrasonic monitoring or buoyancy adjustment to control the liquid level of the nutrient solution of hydroponic plants, and the control process is complicated and cumbersome, and the cost is high.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
