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

[0002] Hydroponics is a method of cultivating plants by placing their roots in nutrient solution or clean water, so that the plants can directly absorb the nutrients and water they need from the water. This method is not only convenient for viewing the growth of plant roots, but also has the advantages of being clean and easy to manage.

[0003] Common hydroponic plants include: green radish, spider plant and pennywort, etc.

[0006] The above patents all have the same problem, no matter whether the plant fixing tube or the first fixing ring or the second fixing ring has a fixed size, if the plant is changed or the plant grows, the components used for planting need to be re-adapted or replaced, which is time-consuming and labor-intensive. In view of this, the inventor has proposed a hydroponic plant cultivation device. Summary of the invention

[0007] The purpose of the present invention is to solve the problem that the planting components of the traditional plant cultivation equipment used for planting cannot adapt to new hydroponic plants and the hydroponic plants that continue to grow.

[0008] In order to achieve the above object, the present invention provides the following basic scheme:

[0009] A hydroponic plant cultivation device comprises a cultivation cylinder, a water changing cover detachably connected to the bottom of the cultivation cylinder, a planting assembly detachably connected to the top of the cultivation cylinder, and a fixing plate detachably connected inside the cultivation cylinder;

[0010] The planting assembly includes a top ring detachably connected to the top of the cultivation tube, a sleeve ring fixed to the top ring, and a plurality of planting rods arranged in the sleeve ring and rotatably connected to the sleeve ring;

[0011] The center of the fixed plate is provided with a hydroponic plant main stem positioning hole, a plurality of limiting holes are provided around the hydroponic plant main stem positioning hole, and a positioning ring is provided in the hydroponic plant main stem positioning hole;

[0012] A traction rope is provided at the end of the planting rod, and the other end of the traction rope is connected to a positioning ring;

[0013] The planting rod is also provided with a limiting component, and the limiting component cooperates with the limiting hole to control the rotation angle of the planting rod.

[0014] The principles and effects of this basic solution are:

[0015] 1. Compared with the prior art, the present device has a simple structure and a more ingenious design. The present device is a hydroponic plant cultivation equipment with a planting function, which is suitable for replacing new types of hydroponic plants and continuing to grow hydroponic plants. Compared with traditional hydroponic plant cultivation equipment with a planting function, the present device is more competitive in the market, and there are no difficult problems in terms of cost and process, and it has market value.

[0016] 2. Compared with the prior art, this device divides hydroponic plants into root system, stem and branches and leaves. For the root system, a fixing plate is used so that the root system is located below the fixing plate. Similar to the traditional hydroponic plant cultivation equipment, a hydroponic plant main stem positioning hole is opened at the center of the fixing plate. The main stem positioning hole of the hydroponic plant is used to determine the approximate growth position of the hydroponic plant. As the hydroponic plant grows, the stem grows and becomes thicker, and the branches and leaves begin to flourish. If no intervention is made, the growth direction cannot be controlled. Based on this starting point, this case is designed. This device is provided with a rotationally connected to the ring. The stem grows and thickens, causing the planting rods to rotate upward. The growth and thickening of the stem will not affect the general growth direction of the hydroponic plant because of the presence of the main stem positioning hole of the hydroponic plant. However, there is a small range of growth deviation. Therefore, a limit assembly is provided. The limit assembly cooperates with the limit hole to control the rotation angle of the planting rod. The rotation angle of the planting rod can be artificially controlled. When the rotation angle of the planting rod is controlled, the small range of growth deviation (side branches or side stems) is blocked by the planting rod, so that the growth of the hydroponic plant returns to the correct track, that is, always upward.

[0017] 3. Compared with the prior art, a traction rope is provided at the end of the planting rod, and the other end of the traction rope is connected to a positioning ring. When the hydroponic plants grow, the planting rod tilts upward, and the traction rope drives the positioning ring to move upward. The positioning ring cooperates with the positioning hole of the main stem of the hydroponic plant to fix the double-point position of the main stem of the hydroponic plant. Because of the growth of the stem, the double-point position fixation is used to ensure that the approximate growth position of the hydroponic plant does not change and remains vertical.

[0018] Furthermore, a water leakage hole is opened at the bottom of the cultivation tube, a threaded groove is opened on the inner wall of the water leakage hole, a connecting thread is arranged on the outer wall of the water changing cover, the water changing cover is threadedly connected to the water leakage hole and a sealing gasket is arranged at the connection between the water changing cover and the water leakage hole.

[0019] Furthermore, a ring groove is formed at the top of the cultivation tube, and the ring groove is threadedly connected to the top ring. After the ring groove is threadedly connected to the top ring, the highest point of the sleeve ring is higher than the top of the cultivation tube.

[0020] Furthermore, the cultivation tube is a conical tube, the size of the head of the conical tube is larger than the size of the bottom of the conical tube, and the size of the fixing plate is equal to the center line length of the waistline of the conical tube.

[0021] Furthermore, an installation groove is formed on the inner wall of the collar, installation points are evenly installed in the installation groove, a rotatable rotating shaft is installed on the installation point, the planting rod is connected to the rotating shaft, and the end points of the planting rod all point to the center of the collar.

[0022] Furthermore, the planting rod comprises a main rod, a secondary rod threadedly connected to the main rod, and a rubber ball arranged at the end of the secondary rod and in contact with the hydroponic plants, and the traction rope is installed on the rubber ball.

[0023] Furthermore, the limiting assembly includes a first hole opened at one end of the main rod, a second hole at the other end of the main rod, a connecting rope, a blocking block and an iron ring, one end of the connecting rope is connected to the iron ring, and the other end of the connecting rope passes through the first hole to connect to the blocking block. A magnet sheet is provided on the inner wall of the positioning ring, and the magnet sheet can be magnetically connected to the iron ring.

[0024] Furthermore, when the hydroponic plants grow, the planting rods tilt upward, the traction rope drives the positioning ring to move upward, and the positioning ring cooperates with the positioning holes of the main stems of the hydroponic plants to fix the double-point positions of the main stems of the hydroponic plants.

[0025] Furthermore, the sleeve ring is made of transparent plastic material.

[0026] Furthermore, after the water-changing cover is threadedly connected to the water leakage hole, the portion of the water-changing cover located inside the cultivation tube is higher than the inner bottom surface of the cultivation tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] 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.

[0036] The figure marks in the drawings of the specification include: cultivation cylinder 1, water change cover 2, connecting thread 3, sealing gasket 4, ring groove 5, fixing plate 6, limiting hole 7, top ring 8, sleeve ring 9, installation groove 10, planting rod 11, main rod 1101, auxiliary rod 1102, traction rope 1104, first hole 1105, leakage hole 12, installation point 13, rotating shaft 14, rubber ball 15, hydroponic plant 16, positioning ring 17, hydroponic plant main stem positioning hole 18, blocking block 19, iron ring 20, connecting rope 21.

[0037] Implementation example Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown:

[0038] A hydroponic plant cultivation device, comprising a cultivation tube 1, a water changing cover 2 detachably connected to the bottom of the cultivation tube 1, a planting assembly detachably connected to the top of the cultivation tube 1, and a fixing plate 6 detachably connected inside the cultivation tube 1;

[0039] About the overall structure:

[0040] A water leakage hole 12 is provided at the bottom of the cultivation tube 1, a threaded groove is provided on the inner wall of the water leakage hole 12, a connecting thread 3 is provided on the outer wall of the water change cover 2, the water change cover 2 is threadedly connected to the water leakage hole 12, and a sealing gasket 4 is provided at the connection between the water change cover 2 and the water leakage hole 12.

[0041] Specifically, the purpose of setting the water leakage hole 12 and the water changing cover 2 is to realize the overall water changing process. By opening the water changing cover 2, all the water can be changed, which is more convenient. A sealing gasket 4 is provided to improve the connection sealing characteristics of the above two and avoid water leakage.

[0042] like Figure 3 As shown, after the water-changing cover 2 is threadedly connected to the water leakage hole 12, the portion of the water-changing cover 2 located inside the cultivation barrel 1 is higher than the inner bottom surface of the cultivation barrel 1. Since it is a hydroponic plant 16, the roots are all in the water, and a certain amount of adhesive covering is required to improve the survival rate of the roots. Therefore, the portion of the water-changing cover 2 located inside the cultivation barrel 1 is higher than the inner bottom surface of the cultivation barrel 1.

[0043] A more ingenious structural connection is adopted on the fixing plate 6:

[0044] The cultivation tube 1 is a conical tube, the size of the head of the conical tube is larger than the size of the bottom of the conical tube, and the size of the fixing plate 6 is equal to the center line length of the waistline of the conical tube;

[0045] Specifically: the fixing plate 6 is put into the cultivation tube 1. Since the size of the head of the conical tube is larger than the bottom of the conical tube and the size is decreasing, the fixing plate 6 stops fixing at the center line of the waistline.

[0046] The planting assembly includes a top ring 8 detachably connected to the top of the cultivation tube 1, a sleeve ring 9 fixed to the top ring 8, and a plurality of planting rods 11 arranged in the sleeve ring 9 and rotatably connected to the sleeve ring 9;

[0047] About the rotating planting rod 11:

[0048] like Figure 3 As shown, the inner wall of the ring 9 is provided with a mounting groove 10, and mounting points 13 are evenly installed in the mounting groove 10. A rotatable rotating shaft 14 is installed on the mounting point 13. The planting rod 11 is connected to the rotating shaft 14, and the end points of the planting rod 11 all point to the center of the ring 9. The ring 9 is made of transparent plastic material to improve the light transmittance of the ring 9.

[0049] Since the rotating shaft 14 is rotatable and the implanting rod 11 is connected to the rotating shaft 14, the implanting rod 11 can naturally rotate based on the setting of the rotating shaft 14. Figure 3 It can be seen that the rotation of the planting rod 11 is in the up and down direction;

[0050] An annular groove 5 is formed on the top of the cultivation tube 1 , and the annular groove 5 is threadedly connected to the top ring 8 . After the annular groove 5 is threadedly connected to the top ring 8 , the highest point of the sleeve ring 9 is higher than the top of the cultivation tube 1 .

[0051] The overall disassembly of the planting component is achieved, making installation and replacement of the planting component convenient.

[0052] The fixing plate 6 has a hydroponic plant main stem positioning hole 18 at its center, and a plurality of limiting holes 7 are formed around the hydroponic plant main stem positioning hole 18. A positioning ring 17 is provided in the hydroponic plant main stem positioning hole 18.

[0053] A traction rope 1104 is provided at the end of the planting rod 11, and the other end of the traction rope 1104 is connected to the positioning ring 17;

[0054] The planting rod 11 is also provided with a limiting assembly, and the limiting assembly cooperates with the limiting hole 7 to control the rotation angle of the planting rod 11.

[0055] About planting rod 11:

[0056] The planting rod 11 includes a main rod 1101 , a secondary rod 1102 threadedly connected to the main rod 1101 , and a rubber ball 15 disposed at an end position of the secondary rod 1102 and in contact with the hydroponic plant 16 , and the traction rope 1104 is installed on the rubber ball 15 .

[0057] The limiting assembly includes a first hole 1105 opened at one end of the main rod 1101, a second hole at the other end of the main rod 1101, a connecting rope 21, a blocking block 19 and an iron ring 20. One end of the connecting rope 21 is connected to the iron ring 20, and the other end of the connecting rope 21 passes through the first hole 1105 to connect to the blocking block 19. A magnet sheet is arranged on the inner wall of the positioning ring 17, and the magnet sheet can be magnetically connected to the iron ring 20.

[0058] Specific implementation process:

[0059] In the first step, the growth and development of the hydroponic plant 16 is described in detail as an example. First, the root system of the hydroponic plant 16 passes through the main stem positioning hole 18 of the hydroponic plant and is located below the fixing plate 6, and the root system is supported on the water changing cover 2;

[0060] In the second step, the stem above the root system passes through the main stem positioning hole 18 of the hydroponic plant above the fixing plate 6. At this time, the main stem positioning hole 18 of the hydroponic plant determines the approximate growth direction of the hydroponic plant 16, that is, vertically upward growth;

[0061] In the third step, when the hydroponic plant 16 grows, the stem becomes longer and thicker. At this time, the longer and thicker stem will act on the planting rod 11. Figure 4 , which will cause the planting rod 11 to tilt upward. When the planting rod 11 tilts upward, the guide rope drives the positioning ring 17 to move upward, and the positioning ring 17 cooperates with the main stem positioning hole 18 of the hydroponic plant to fix the double-point position of the main stem of the hydroponic plant 16.

[0062] The double-point position is fixed because the approximate growth direction of the hydroponic plant 16 will be offset as the stem becomes longer and thicker. The double-point position fixation can correct the approximate growth direction of the hydroponic plant 16 to ensure that the approximate growth direction of the hydroponic plant 16 is still vertically upward;

[0063] In the third step, the stem becomes longer and thicker, which will inevitably lead to the luxuriance of branches and leaves (i.e. the generation of side branches and deviated stems). In order to ensure that the entire growth is not deviated in the vertical upward direction, a limit assembly is required at this time. The magnet sheet can be magnetically connected to the iron ring 20, so that the hydroponic plant 16 cannot continue to rotate against the planting rod 11. At this time, the planting rod 11 plays a role in preventing the deviated growth. This effect can minimize the impact of the side branches and deviated stems. For details, see Figure 4 ;

[0064] Regarding the use of a magnet sheet that can be magnetically connected to the iron ring 20 to limit the rotation of the planting rod 11, this article further describes:

[0065] Since the magnet sheet can be magnetically connected to the iron ring 20, a certain limiting force is generated, and Figure 7 As shown, there are multiple limiting holes 7, and the limiting force generated can be large or small. The limiting force hinders the planting rod 11 from rotating upward due to the lengthening and thickening of the stem. The rotational force is smaller than the limiting force, which limits the rotation of the planting rod 11.

[0066] The present invention further elaborates on the role of the planting rod 11 in preventing offset growth;

[0067] At this time, the side branches and stems will be blocked by the planting rod 11. The planting rod 11 has a sub-rod 1102. The sub-rod 1102 can be fixed in size and width. Since the angle is fixed, when the width of the sub-rod 1102 is determined, most of the side branches and stems will not grow wildly beyond the width of the sub-rod 1102. Based on this, the planting of the hydroponic plants 16 is completed.

[0068] Finally, since the planting rods 11 in this case are in a rotatable state before the limiting assembly is used, this case is suitable for new hydroponic plants 16, that is, new hydroponic plants 16 of different types can still be used.

[0069] The device solves the problem that the planting components of the conventional plant cultivation equipment used for planting cannot adapt to the new hydroponic plants 16 and the hydroponic plants 16 that continue to grow.

[0070] 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.
