[0027] Various exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0028] The first embodiment is a three-dimensional vegetable hydroponic device, comprising a support frame 1, wherein a plurality of pipe supports 2 are installed at intervals in the vertical direction of the support frame 1, a hydroponic pipe 3 is installed on the pipe support 2, and a plurality of hydroponic troughs 4 arranged at intervals are provided on the hydroponic pipe 3. When in use, the plants to be cultivated are placed inside the hydroponic trough 4, and the pipe supports 2 grow in sequence from top to bottom, so that the hydroponic plants above and below will not block each other. A water inlet 5 is provided at one end of the hydroponic pipe 3, and a pumping device for injecting water into the water inlet 5 of the uppermost hydroponic pipe is fixedly installed on the support frame 1. The pumping device adopts a water pump. When in use, the water pump is fixedly installed on the support frame 1, and the water pump draws water from the water inlet 5 at the water tank 12 into the hydroponic pipe 3. A cleaning pipe 6 is installed at the other end of the hydroponic pipe 3. A rotating groove 7 is provided at the end of the cleaning pipe 6 away from the hydroponic pipe 3, and a water outlet 8 is provided at the bottom of the rotating groove 7. A rotating ring 9 is rotatably connected inside the rotating groove 7, and a plurality of filter holes 10 are provided on the outer edge surface of the rotating ring 9. The lower end of the cleaning pipe 6 is fixedly connected to a drainage pipe 11, which is located below the water outlet 8. The lower end of the drainage pipe 11 is located above the water inlet 5 of the hydroponic pipe 3 below. A driving structure for driving the rotating ring 9 to rotate is installed on the cleaning pipe 6. When in use, the rotating ring 9 is pushed to rotate by the driving structure; a water tank 12 is fixedly installed at the bottom end of the support frame 1, and the water tank 12 is used to collect water flowing out of the drainage pipe 11 on the cleaning pipe 6 at the bottom, and the water in the water tank 12 is pumped to the top through a water pump and flows into the water inlet 5;

[0029] During use, water enters from the water inlet 5 of the top hydroponic pipe 3 and flows out from the water outlet 8. The plant roots and fallen leaves inside the hydroponic pipe 3 are isolated into the rotating ring 9, and the water flows into the drainage pipe 11 through the filter holes 10. The rotating ring 9 is rotated to drive the plant roots and fallen leaves at the bottom of the rotating ring 9 to the top of the cleaning pipe 6. Under the action of gravity, the plant roots and fallen leaves inside the rotating ring 9 fall, and the water flows into the water inlet 5 of the hydroponic pipe 3 below, and then flows into the water tank 12 in sequence.

[0030] The driving structure includes a fixing frame 13 fixedly mounted on the end of the cleaning pipe 6 away from the hydroponic pipe 3, and a gravity water tank 14 is slidably connected inside the fixing frame 13. A tension spring 15 is installed between the gravity water tank 14 and the fixing frame 13. In the initial position, the gravity water tank 14 is pulled upward by the action of the tension spring 15, and a water storage pipe 16 located at the upper end of the gravity water tank 14 is installed on the cleaning pipe 6. The water inside the cleaning pipe 6 slowly flows into the gravity water tank 14 through the water storage pipe 16. The gravity water tank 14 A support plate 17 is installed on one side, and a sliding pin 18 is slidably connected to the support plate 17. A tensioning spring 19 is installed between the sliding pin 18 and the support plate 17. A plurality of fixed rods 20 arranged at intervals are fixedly connected to the rotating ring 9. One end of the fixed rod 20 close to the fixed frame 13 is fixedly connected to a toggle rod 21 that cooperates with the sliding pin 18. In the initial position, the sliding pin 18 is pushed towards the toggle rod 21 under the action of the tensioning spring 19. The cross-section of the toggle rod 21 is set to a right-angled trapezoid.

[0031] When in use, the gravity water tank 14 slides downward under the action of gravity, and the sliding pin 18 contacts the straight edge of the toggle rod 21, so that the sliding pin 18 drives the toggle rod 21 to slide downward, thereby causing the toggle rod 21 to drive the rotating ring 9 to rotate. When the gravity water tank 14 slides upward, the sliding pin 18 contacts the inclined surface of the toggle rod 21, and under the guidance of the inclined surface of the toggle rod 21, the sliding pin 18 is pushed in the direction away from the toggle rod 21 until the sliding pin 18 and the toggle rod 21 are disengaged. The sliding pin 18 is pushed in the direction close to the toggle rod 21 under the action of the tensioning spring 19, and this reciprocating cycle is carried out; the lower end of the gravity water tank 14 is provided with a water outlet structure, and the lower end of the fixing frame 13 is provided with a water collecting guide groove 23. The water collecting guide groove 23 is connected to the water storage tank 12 through a pipe. The water inside the gravity water tank 14 flows into the water storage tank 12 through the water guide groove 23 and the pipe.

[0032] The water outlet structure includes a plurality of drain ports 24 spaced apart at the lower end of the gravity water tank 14. When in use, the water inside the gravity water tank 14 flows out from the drain port 24. An L-shaped limit plate 25 is slidably connected to one side of the gravity water tank 14. A plurality of matching ports 26 that match the drain port 24 are formed on the lower end surface of the limit plate 25. A return spring 27 is installed between the limit plate 25 and the gravity water tank 14. When in use, the initial position is in the action of the return spring 27, which pulls the limit plate 25 to slide, so that the drain port 24 and the matching port 26 are not connected. The limit plate 25 blocks the drain port 24, so that the water inside the gravity water tank 14 does not flow out. A pushing block 28 with a right-angled trapezoidal cross section is fixedly connected to the right side of the limit plate 25. The fixing frame 13 is fixedly connected to a pushing fixed block 28. The fixed plate 29 pushes the fixed plate 29 to be fixedly connected with a matching block 30 that matches the pushing block 28. The cross-section of the matching block 30 is set to a right-angled trapezoid. A one-way check device is set on one side of the cleaning pipe 6. When the gravity water tank 14 slides downward, the inclined surface of the pushing block 28 and the matching block 30 push the limit plate 25 to slide, so that the water outlet 24 and the matching port 26 are connected, and the water inside the gravity water tank 14 flows out, so that the gravity water tank 14 slides upward to the initial position under the action of the tension spring 15. When the gravity water tank 14 slides upward, under the action of the reset spring 27, the limit plate 25 is pulled to slide, so that the water outlet 24 and the matching port 26 are not connected, and the limit plate 25 blocks the water outlet 24, so that the water inside the gravity water tank 14 does not flow out.

[0033] The one-way check device includes a check bracket 36 fixedly connected to one side of the cleaning pipe 6. A one-way check slider 37 that cooperates with the fixed rod 20 is slidably connected to the check bracket 36. The cross-section of the one-way check slider 37 is set to be trapezoidal. A check spring 38 is installed between the one-way check slider 37 and the check bracket 36. In the initial state, under the action of the check spring 38, the one-way check slider 37 is pulled in the direction close to the fixed rod 20;

[0034] When the rotating ring 9 is driven to rotate, the fixed rod 20 on the rotating ring 9 contacts the inclined surface of the one-way check slider 37, and the fixed rod 20 pushes the one-way check slider 37 in the direction away from the rotating ring 9, compressing the check spring 38. When the one-way check slider 37 and the fixed rod 20 are disengaged, under the action of the check spring 38, the one-way check slider 37 is pulled in the direction close to the rotating ring 9, and the straight surface of the one-way check slider 37 contacts the fixed rod 20, thereby preventing the rotating ring 9 from rotating in the opposite direction.

[0035] Example 2. Based on Example 1, when the rotating ring 9 rotates, the plant roots and branches inside the rotating ring 9 are likely to fall to the bottom of the rotating ring 9 and cannot move upward with the rotating ring 9. Therefore, this embodiment provides a barrier structure to solve the above problem. Specifically, a plurality of barrier plates 31 are arranged at intervals inside the rotating ring 9. When in use, when the rotating ring 9 rotates, the barrier plates 31 drive the plant roots and branches to move upward.

[0036] Example three, based on Example one, this example provides a collection structure. Specifically, a collection groove 32 is opened at the upper end of the cleaning pipe 6, and a collection box 33 is slidably connected inside the collection groove 32. When the rotating ring 9 rotates, it drives the roots and branches of the plant to move upward. When the rotating ring 9 drives the roots and branches of the plant to rotate to the top, they fall into the collection box 33 under the action of gravity.

[0037] A cleaning brush 34 is fixedly connected to the collecting box 33 . The cleaning brush 34 is used to clean the inside of the rotating ring 9 . When the rotating ring 9 rotates, the cleaning brush 34 cleans the plant roots and branches inside the rotating ring 9 and drops them into the collecting box 33 .

[0038] Example 4. Based on Example 1, this example provides a stirring device. Specifically, a stirring blade 35 is installed inside the water tank 12. The stirring blade 35 is connected to a driving device. The driving device adopts a driving motor. When in use, the driving motor is used to drive the stirring blade 35 to rotate. When adding nutrients inside the water tank 12, the stirring blade can stir it to make it more uniform in the water.

[0039] When implementing:

[0040] The water pump draws water to the top, and the water enters from the water inlet 5 of the top hydroponic pipe 3 and flows out from the water outlet 8. The plant roots and fallen leaves inside the hydroponic pipe 3 are isolated inside the rotating ring 9, and the water flows through the filter hole 10 into the drainage pipe 11.

[0041] The water inside the cleaning pipe 6 slowly flows into the gravity water tank 14 through the water storage pipe 16. The gravity water tank 14 slides downward under the action of gravity, and the sliding pin 18 contacts the straight edge of the toggle rod 21, so that the sliding pin 18 drives the toggle rod 21 to slide downward, so that the toggle rod 21 drives the rotating ring 9 to rotate. When the rotating ring 9 drives the roots and branches of the plant to rotate to the top, they fall into the collection box 33 under the action of gravity; when the gravity water tank 14 slides downward under the action of gravity, it drives the rotating ring 9 to rotate, and the fixed rod 20 on the rotating ring 9 contacts the inclined surface of the one-way check slider 37. The fixed rod 20 pushes the one-way check slider 37 in the direction away from the rotating ring 9, compressing the check spring 38.

[0042] When the gravity water tank 14 slides downward, the inclined surface of the pushing block 28 and the matching block 30 push the limit plate 25 to slide, so that the water outlet 24 and the matching port 26 are connected, and the water inside the gravity water tank 14 flows out, so that the gravity water tank 14 slides upward to the initial position under the action of the tension spring 15. When the gravity water tank 14 slides upward, under the action of the return spring 27, the limit plate 25 is pulled to slide, so that the water outlet 24 and the matching port 26 are not connected, and the limit plate 25 blocks the water outlet 24, so that the water inside the gravity water tank 14 does not flow out.

[0043] When the gravity water tank 14 slides upward, the sliding pin 18 contacts the inclined surface of the toggle rod 21, and under the guidance of the inclined surface of the toggle rod 21, the sliding pin 18 is pushed in the direction away from the toggle rod 21 until the sliding pin 18 and the toggle rod 21 are disengaged, and then the sliding pin 18 is pushed in the direction close to the toggle rod 21 under the action of the tensioning spring 19; when the gravity water tank 14 slides upward, under the action of the check spring 38, the one-way check slider 37 is pulled in the direction close to the rotating ring 9, and the straight surface of the one-way check slider 37 contacts the fixed rod 20, thereby preventing the rotating ring 9 from rotating in the opposite direction, and so on.

[0044] The present invention aims at an existing three-dimensional vegetable hydroponic device, and solves the problem that the roots and branches of cultivated plants are easy to fall off and fall into the hydroponic pipe and flow to the water outlet with the water flow, and the water outlet is easily blocked after long-term use, thereby causing the water in the hydroponic pipe to flow out from the upper water inlet. Over time, the water flow in the hydroponic pipe does not flow, resulting in the lack of oxygen and the easy death of plants; by adding a fixing frame, a gravity water tank, a tension spring, a water storage pipe, a support plate, a sliding pin, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod, a pull rod The tightening spring, the fixing rod, the toggle rod, the water collecting and guiding groove, the water outlet, the limit plate, the matching port, the reset spring, the pushing block, the pushing fixing plate and the matching block are configured to slowly inject water into the gravity water tank, and the gravity water tank slides downward under the action of gravity, and the rotating ring is driven to rotate under the action of the sliding pin and the toggle rod, thereby realizing automatic control of the rotation of the rotating ring and cleaning the foreign matter inside the rotating ring; by adding stirring blades, the oxygen of the water flow inside the water storage tank is increased, and when the nutrients are added inside the water storage tank, the stirring blades can stir it to make it more uniform in the water; the present invention is easy to use and can effectively clean foreign matter such as plant roots at the water outlet.
