Description

Technical Field

[0001] This utility model relates to the field of planting technology, and more specifically, to a three-dimensional eggplant planting device. Background Technology

[0002] Existing water supply systems often rely on timed or intermittent water supply, resulting in insufficient and unstable water supply. In some designs, the water supply may be affected by pressure fluctuations or improper water supply pipeline design, leading to intermittent interruptions or fluctuations in water supply. This makes it impossible to ensure that the eggplant seedlings receive continuous and stable water during their growth. During the water supply process, due to unreasonable layout, design, or connection methods of the water pipes, the water flow may be uneven among different planting pipes, resulting in insufficient water supply in some planting pipes while water accumulation may occur in other planting pipes, affecting the growth environment of the eggplant seedlings. The effect of continuous water supply cannot be guaranteed, leading to uneven distribution of water resources in the entire planting system, and may even cause problems such as root rot or eggplant seedling wilting.

[0003] In existing technologies, the regulation of water flow rate and volume often requires manual operation, and the adjustment methods are rather cumbersome. For example, using valves, regulating valves, and other devices to control the water flow rate and volume may have limited adjustment ranges or be inconvenient to operate. Manual adjustment requires sufficient understanding of the water flow status of the system and often relies on manual judgment and adjustment, which can easily lead to errors and thus affect the water supply to the eggplant seedlings. Existing water supply systems have low precision in regulating water flow rate and volume, and cannot achieve fine-tuning. In some designs, the water flow rate and volume can only be controlled by simple flow meters and regulating valves, but these devices have a narrow adjustment range and cannot be flexibly adjusted according to different planting stages, the water requirements of the eggplant seedlings, or changes in the external environment.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a three-dimensional eggplant planting device, which has the following features:

[0017] Beneficial effects:

[0018] This invention features a continuous water supply mechanism. Through the coordination of a water supply pipe, planting pipe, connecting pipe, and return pipe, the continuous water supply mechanism can achieve a stable water supply, ensuring that the eggplant seedlings receive continuous water throughout their growth process. This avoids water supply interruptions or instability. The multiple planting pipes are arranged in a stepped manner, and the presence of connecting pipes ensures that the water flow is evenly distributed to each planting pipe, allowing each eggplant seedling to receive an appropriate amount of water, thereby promoting balanced growth. The return pipe collects water from the bottom, forming a water circulation system, which saves water resources, improves the efficiency of the water supply system, and reduces water waste.

[0019] This invention incorporates a flow rate regulation mechanism. Through the cooperation of a regulating pipe, an elastic plate, a support spring, a directional ring, a threaded frame, and a threaded rod, this mechanism precisely regulates the water flow rate within the water supply pipe. This ensures that the flow rate can be flexibly adjusted according to needs, thereby meeting the water requirements of different eggplant seedling growth stages. The combination of the elastic plate and the support spring automatically adjusts the water flow, ensuring its stability. Even under fluctuating water pressure, a constant flow rate is maintained, preventing excessively fast or slow flow from affecting seedling growth. The combination of the threaded rod and the threaded frame makes flow rate regulation more precise, allowing for meticulous control of water flow and preventing uneven or excessive water supply, thus optimizing water resource utilization efficiency.

[0020] This utility model is equipped with an adjustment auxiliary mechanism. The adjustment auxiliary mechanism, through the cooperation of a rotating sleeve, a rotating block, a side fixing plate, a tightening block, and a tightening spring, ensures the stable operation of each component during the flow rate adjustment process, avoids errors in flow rate adjustment caused by unstable rotation, and makes the water flow adjustment more accurate and reliable. The design of the centripetal rail and the tightening block makes the adjustment process smoother. The tightening block slides centripetally on the centripetal rail, ensuring that the water flow adjustment component can be adjusted smoothly. The linkage design of the inner rotating sleeve and the rotating sleeve allows the adjustment tube to rotate smoothly, which in turn drives the threaded rod to rotate, ensuring precise control of the water flow.

[0030] Please see Figures 1-5 A three-dimensional eggplant planting device includes a three-dimensional frame 1, a continuous water supply mechanism, a flow rate regulating mechanism, and an auxiliary regulating mechanism. The continuous water supply mechanism includes a water supply pipe 2, planting pipes 3, connecting pipes 4, and a return water pipe 5. Multiple sets of planting pipes 3 are installed in steps on both sides of the three-dimensional frame 1. Connecting pipes 4 are installed between adjacent planting pipes 3. The water supply pipe 2 is connected to the top planting pipe 3, and the return water pipe 5 is connected to the bottom planting pipe 3. The flow rate regulating mechanism is installed at one end of the water supply pipe 2 and includes an regulating pipe 6 and a spring. The device comprises a spring 7, a support spring 8, a directional ring 9, a threaded bracket 10, and a threaded rod 11. Multiple sets of elastic plates 7 are rotatably mounted on the inner wall of the regulating tube 6. The support spring 8 is installed between the elastic plates 7 and the inner wall of the regulating tube 6. The directional ring 9 is directionally slidably mounted on the inner wall of the clamping tube. The threaded bracket 10 is installed on the inner wall of the directional bracket. The threaded rod 11 is rotatably limited within the regulating tube 6, and the threaded bracket 10 is threadedly connected to the threaded rod 11. One end of the directional ring 9 can push one end of the elastic plate 7, causing the elastic plate 7 to adhere to the inner wall of the regulating tube 6.

[0031] In this embodiment, an external water source is input through a water supply pipe 2, which is connected to the top planting pipe 3 of the system. Water enters the planting pipe 3 from the water supply pipe 2, is regulated, and then distributed to the eggplant seedlings in each planting pipe 3. Multiple planting pipes 3 are installed in a stepped manner on both sides of the three-dimensional frame 1. The bottom of each planting pipe 3 is connected to a return water pipe 5. Water flows from the top planting pipe 3 to each planting pipe 3 below, providing moisture to the eggplant seedlings. Connecting pipes 4 are installed between adjacent planting pipes 3 to ensure that water can flow smoothly from one planting pipe 3 to the next. The design of the connecting pipes 4 allows water to circulate between multiple planting pipes 3, thereby ensuring a balanced water supply in each planting pipe 3. The return water pipes 5 guide the water at the bottom of each planting pipe 3 back to the bottom of the system, providing a return channel for water circulation. Water pipe 5 is connected to the planting pipe 3 at the bottom. Water flows back through return pipe 5 to complete a water cycle, preventing the water flow from being too fast or too slow, which would affect the growth of the eggplant seedlings. The water first enters the regulating pipe 6, which is equipped with multiple elastic plates 7. When the water flows through the regulating pipe 6, the elastic plates 7 will deform under the action of the water flow, thereby changing the size of the water flow channel and achieving the effect of regulating the flow rate. The directional ring 9 is installed on the inner wall of the regulating pipe 6 and cooperates with the clamping pipe to ensure the directional sliding of the flow rate regulating device in the regulating pipe 6. One end of the directional ring 9 pushes one end of the elastic plate 7, making it close to the inner wall of the regulating pipe 6, thereby controlling the flow rate of the water. By rotating the threaded rod 11, the position of the threaded bracket 10 can be adjusted, thereby controlling the degree of deformation of the elastic plate 7 in the regulating pipe 6, and thus regulating the speed of the water flow.

[0032] The adjustment auxiliary mechanism includes a rotating sleeve 12, a rotating block 13, a side fixing plate 14, a tightening block 15, and a tightening spring 16. The rotating sleeve 12 is rotatably mounted on the outer wall of the clamping tube. The rotating block 13 is mounted on the bottom end of the rotating sleeve 12. The side fixing plate 14 is fixedly mounted on the outer wall of the adjustment tube 6. Multiple sets of tightening blocks 15 are slidably mounted on the top end of the side fixing plate 14. The tightening spring 16 is mounted between adjacent tightening blocks 15. The inner wall of the tightening block 15 presses against the outer wall of the rotating block 13, so that the rotating block 13 and the rotating sleeve 12 rotate stably.

[0033] When the auxiliary mechanism needs to be adjusted, multiple tightening blocks 15 are mounted on the side fixing plate 14 by radial sliding. Tightening springs 16 are installed between the tightening blocks 15. The inner wall of the tightening block 15 presses against the outer wall of the rotating block 13 to ensure that the rotating block 13 and the rotating sleeve 12 can rotate stably and avoid unnecessary loosening, thus maintaining the stability of the system. A radial rail 20 is installed on the side fixing plate 14. The tightening blocks 15 slide on the radial rail 20 and the tightening force is adjusted by the action of the tightening springs 16. With the cooperation of these accessories, the regulating pipe 6 can rotate stably, ensuring that the water flow regulation is more precise and stable.

[0034] Please see Figures 1-5As a supplementary embodiment of an eggplant three-dimensional planting device to the continuous water supply mechanism, flow rate regulation mechanism, and regulation auxiliary mechanism: An inner rotating sleeve 17 is rotatably mounted on the upper limit of the inner wall of the regulating pipe 6, and the inner rotating sleeve 17 is linked with the rotating sleeve 12. An inner rotating frame 18 is mounted on the inner rotating sleeve 17, and the inner rotating frame 18 is connected to the threaded rod 11. The rotation of the inner rotating frame 18 drives the threaded rod 11 to rotate. A culture dish 19 is provided on the planting pipe 3, and multiple sets of culture dishes 19 are provided. Eggplant seedlings are planted in the culture dishes 19. A side fixing plate 14 is installed with... There is a centripetal rail 20, and multiple sets of centripetal rails 20 are provided. The tightening block 15 is set to slide centripetally on the centripetal rail 20. A connecting plate 21 is installed on one side wall of the regulating pipe 6, and the connecting plate 21 is fixedly installed on the water supply pipe 2. An external pipe 22 is fixedly installed on one end of the return pipe 5 and the water supply pipe 2. One end of one set of external pipes 22 is connected to the connecting plate 21 on the side wall of the regulating pipe 6. The external pipe 22 is connected to the external water supply and return equipment. A bottom wheel 23 is installed at the bottom end of the three-dimensional frame 1, and multiple sets of bottom wheels 23 are provided.

[0035] More specifically, the water source enters the water supply pipe 2 system through the external pipe 22. The water flow begins to enter the top planting pipe 3. When the water flows through the regulating pipe 6, the flow rate regulating mechanism will adjust the water flow speed as needed. The elastic plate 7 will automatically adjust according to the water flow pressure to maintain a constant water flow speed. Through the connecting pipe 4, the water flow is evenly distributed to multiple planting pipes 3. The water flow rate and speed in each planting pipe 3 are controlled by the flow rate regulating mechanism. The water flow in each planting pipe 3 passes through the petri dish 19 to ensure that the eggplant seedlings can fully absorb water. The sufficient water in the petri dish 19 promotes the healthy growth of the eggplant seedlings. The water flow returns to the bottom of the system through the bottom return pipe 5 to provide a circulation path for the water flow, thereby maintaining a continuous water supply. If it is necessary to fine-tune the water flow rate, the user can adjust the flow rate precisely through the adjustment auxiliary mechanism to ensure that the water flow rate in each planting pipe 3 is kept at the optimal state.

[0036] In summary, when the overall equipment is in use or operation: When the continuous water supply mechanism is required, the external water source is input through the water supply pipe 2, which is connected to the top planting pipe 3 of the system. Water enters the planting pipe 3 from the water supply pipe 2, and after adjustment, it is distributed to the eggplant seedlings in each planting pipe 3. Multiple planting pipes 3 are installed in a stepped manner on both sides of the three-dimensional frame 1. The bottom of each planting pipe 3 is connected to the return water pipe 5. The water flows through the top planting pipe 3 to each planting pipe 3 below, providing water for the eggplant seedlings. The connecting pipe 4 is installed between adjacent planting pipes 3 to ensure that the water can flow smoothly from one planting pipe 3 to the next. The design of the connecting pipe 4 allows the water to circulate between multiple planting pipes 3, thereby ensuring the water balance of each planting pipe 3. The return water pipe 5 guides the water at the bottom of each planting pipe 3 back to the bottom of the system, providing a return channel for the water circulation. The return water pipe 5 is connected to the bottom planting pipe 3, and the water flows back through the return water pipe 5 to complete one water cycle.

[0037] When the flow rate regulation mechanism is in operation, to prevent the water flow from being too fast or too slow, which could affect the growth of the eggplant seedlings, the water first enters the regulating pipe 6. Multiple elastic plates 7 are installed inside the regulating pipe 6. Their function is to regulate the speed and flow rate of the water. When the water flows through the regulating pipe 6, the elastic plates 7 deform under the action of the water flow, thereby changing the size of the water flow channel and achieving the effect of regulating the flow rate. A directional ring 9 is installed on the inner wall of the regulating pipe 6 and cooperates with the clamping pipe to ensure the directional sliding of the flow rate regulation device in the regulating pipe 6. One end of the directional ring 9 pushes one end of the elastic plate 7, making it close to the inner wall of the regulating pipe 6, thereby controlling the flow rate of the water. By rotating the threaded rod 11, the position of the threaded bracket 10 can be adjusted, thereby controlling the degree of deformation of the elastic plates 7 inside the regulating pipe 6, and thus regulating the speed of the water flow.

[0038] When the auxiliary mechanism needs to be adjusted, multiple tightening blocks 15 are mounted on the side fixing plate 14 by radial sliding. Tightening springs 16 are installed between the tightening blocks 15. The inner wall of the tightening block 15 presses against the outer wall of the rotating block 13 to ensure that the rotating block 13 and the rotating sleeve 12 can rotate stably and avoid unnecessary loosening, thus maintaining the stability of the system. A radial rail 20 is installed on the side fixing plate 14. The tightening blocks 15 slide on the radial rail 20 and the tightening force is adjusted by the action of the tightening springs 16. With the cooperation of these accessories, the regulating pipe 6 can rotate stably, ensuring that the water flow regulation is more precise and stable.

[0039] Water enters the water supply pipe 2 system through the external pipe 22. The water flow begins to enter the top planting pipe 3. When the water flows through the regulating pipe 6, the flow rate regulating mechanism adjusts the water flow speed as needed. The elastic plate 7 automatically adjusts according to the water flow pressure to maintain a constant water flow speed. Through the connecting pipe 4, the water flow is evenly distributed to multiple planting pipes 3. The water flow rate and speed in each planting pipe 3 are controlled by the flow rate regulating mechanism. The water flow in each planting pipe 3 passes through the petri dish 19 to ensure that the eggplant seedlings can fully absorb water. The sufficient water in the petri dish 19 promotes the healthy growth of the eggplant seedlings. The water flow returns to the bottom of the system through the bottom return pipe 5, providing a circulation path for the water flow and thus maintaining a continuous water supply. If it is necessary to fine-tune the water flow rate, the user can precisely adjust the flow rate through the adjustment auxiliary mechanism to ensure that the water flow rate in each planting pipe 3 is kept at the optimal level.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
