Description

Technical Field

[0001] This application relates to the field of irrigation for tea seedling cultivation, and in particular to an irrigation device for tea seedling cultivation. Background Technology

[0002] During the cultivation of tea seedlings, in order to promote their healthy and efficient growth and lay a good foundation for the subsequent cultivation of mature plants, it is necessary to irrigate the tea seedlings through irrigation devices to ensure that they have sufficient water and guarantee their normal growth.

[0003] The existing publication number CN210726138U discloses an irrigation device for tea seedling cultivation, but it still has the following shortcomings in practical use:

[0004] The device irrigates seedlings using water mist generated by atomizing nozzles. However, the water mist is easily diffused by airflow, and a large amount of water evaporates before it comes into contact with the seedlings or soil, resulting in a waste of water resources. At the same time, the water mist mainly acts on the surface of the seedlings and the air, with only a small amount penetrating into the root zone of the soil. Long-term use can easily lead to water shortage in the seedling roots, affecting the seedlings' rooting and nutrient absorption, thus impacting their growth. Utility Model Content

[0005] In order to improve the problem that the water mist generated by the atomizing nozzle can only penetrate a small amount of the soil root area, resulting in root dehydration and affecting the normal growth of seedlings, this application provides an irrigation device for tea seedling cultivation.

[0006] The irrigation device for tea seedling cultivation provided in this application adopts the following technical solution:

[0007] A tea seedling cultivation irrigation device includes a water guide pipe and a cultivation seat. A mounting frame is fixedly provided on one side of the surface of the cultivation seat. A water return plate is fixedly provided on one side of the surface of the cultivation seat near the mounting frame. A plurality of cultivation seats for cultivating tea seedlings are fixedly provided on one side of the surface of the water return plate. An atomizing irrigation mechanism for atomizing irrigation of tea seedlings and a drip irrigation mechanism for drip irrigation are provided on one side of the surface of the water guide pipe near the cultivation seat.

[0008] The atomizing irrigation mechanism includes a T-shaped tube fixed on the side of the mounting frame away from the culture base surface. An atomizing nozzle for spraying water is provided at the end of the T-shaped tube near the culture base. An adjusting tube that is slidably disposed at the end of the T-shaped tube near the culture base is fixed at the end of the atomizing nozzle near the T-shaped tube. A positioning rod for positioning the adjusting tube is slidably disposed on one side of the surface of the T-shaped tube. A plurality of positioning holes that are adapted to the positioning rod are opened on the surface of the adjusting tube.

[0009] The drip irrigation mechanism includes a water supply pipe installed inside the mounting frame. Multiple drip tubes for dripping water are fixed on the side of the water supply pipe near the cultivation base. The drip tubes are installed at a 45-degree angle on the surface of the water supply pipe. A limiting block for limiting the position of the water supply pipe is provided at the end of the water supply pipe away from the water guide pipe.

[0010] By adopting the above technical solution, the drip irrigation mechanism provides targeted water supply to the seedlings, directly delivering water to the soil around the roots and avoiding ineffective water loss. This matches the water absorption needs of the roots and reduces growth differences caused by uneven water distribution. At the same time, the atomizing irrigation mechanism can regulate air humidity. When the air is dry, the atomization increases the air moisture content around the seedlings, compensating for the shortcomings of simple drip irrigation in regulating air humidity and creating a more comfortable microenvironment for the seedlings. The height of the atomizing nozzle can be adjusted by adjusting the pipe and positioning rod, allowing the atomizing nozzle to apply most of the water mist to the seedling area.

[0011] Preferably, the atomizing irrigation mechanism further includes a water inlet pipe fixed on the surface of the water inlet pipe, a solenoid valve fixed at the end of the water inlet pipe away from the water inlet pipe, a water outlet pipe fixed at the end of the solenoid valve away from the water inlet pipe, and a conduit fixed on the surface of the water outlet pipe away from the solenoid valve, which is attached to the end of the T-shaped pipe near the water outlet pipe.

[0012] By adopting the above technical solution, water is drawn out from the water inlet pipe, and then enters the water outlet pipe through the solenoid valve. The solenoid valve controls the flow of water, and the water is diverted from the water outlet pipe to the conduit pipe. The water then flows from the conduit pipe to the T-shaped pipe, and then enters the second water inlet pipe from the T-shaped pipe. Finally, the water is sprayed out through the atomizing nozzle to achieve atomized irrigation of the seedlings.

[0013] Preferably, a driving block is fixed at the end of the positioning rod away from the adjusting tube, a limiting plate is fixed on the surface of the positioning rod and slidably disposed on the side of the T-shaped tube near the surface of the driving block, protrusions are fixed on both sides of the surface of the limiting plate and slidably disposed on the side of the T-shaped tube near the surface of the driving block, and a spring is fixed inside the T-shaped tube on the side of the protrusions near the surface of the driving block.

[0014] By adopting the above technical solution, the driving block is pulled in a direction away from the surface of the T-shaped tube, so that the driving block provides power to the positioning rod, causing the positioning rod to gradually move away from the adjusting tube. As a result, the end of the positioning rod away from the driving block gradually disengages from the interior of the positioning hole. After the end of the positioning rod away from the driving block is completely disengaged from the interior of the positioning hole, the positioning rod releases its positioning of the adjusting tube, allowing the adjusting tube to slide inside the T-shaped tube, thereby adjusting the height of the atomizing nozzle.

[0015] Preferably, the drip irrigation mechanism further includes a second water inlet pipe fixed on the surface of the water inlet pipe, a second solenoid valve fixed at the end of the second water inlet pipe away from the water inlet pipe, a second water outlet pipe fixed at the end of the second solenoid valve away from the second water inlet pipe, and a plurality of second conduits rotatably disposed on the surface of the second water outlet pipe near the end of the water inlet pipe.

[0016] By adopting the above technical solution, water is drawn out from the water inlet pipe 2 and then enters the water outlet pipe 2 through the solenoid valve 2. The solenoid valve 2 controls the flow of water, and the water is diverted from the water outlet pipe 2 to the conduit pipe 2. The water then flows from the conduit pipe 2 to the water delivery pipe, and then from the water delivery pipe into the drip irrigation pipe. The water drips out from the drip irrigation pipe to irrigate the seedlings.

[0017] Preferably, the end of the water supply pipe away from the water guide pipe is fixedly provided with a rotating shaft that is rotatably disposed on the inner wall of the mounting frame, the limiting block is fixedly disposed on the surface of the rotating shaft, the end of the rotating shaft away from the water supply pipe is fixedly provided with a rotating block, and the side of the mounting frame near the rotating block is fixedly provided with a limiting seat that abuts against the limiting block.

[0018] By adopting the above technical solution, the rotating block provides power to the rotating shaft, causing the rotating shaft to rotate. The rotating shaft drives the water supply pipe to rotate, and the water supply pipe drives the drip tube to rotate, causing the drip tube to rotate 180 degrees. This prevents the drip tube from interfering with the seedling cultivation process. After the rotation, the drip tube's own weight and the support of the limiting seat will prevent the water supply pipe from rotating on its own without being subjected to external force.

[0019] Preferably, a water return plate is fixed on the side of the cultivation seat near the mounting frame. The surface of the water return plate is provided with water return holes for water return and a cultivation seat for cultivating tea seedlings is fixed thereon. The interior of the cultivation seat is provided with a water return cavity communicating with the water return holes. The side wall of the water return cavity is provided with a water return component for water return.

[0020] By adopting the above technical solution, excess water or water mist that is not sprayed on the seedling area is collected into the water return chamber through the water return hole, and then the water is introduced into the water pipe by the water return component, thus avoiding the waste of too much water resources.

[0021] Preferably, the water return assembly includes a water return pipe fixed to the side wall of the water return chamber, a processing pipe inserted at the end of the water return pipe away from the culture seat, a sealing ring one fixed at the end of the water return pipe away from the culture seat and snapped into the processing pipe near the end of the water return pipe, a guide pipe inserted at the end of the processing pipe away from the water return pipe, and a sealing ring two fixed at the end of the guide pipe near the processing pipe and snapped into the processing pipe away from the water return pipe.

[0022] By adopting the above technical solution, the water in the return water chamber is discharged through the return water pipe, the water is discharged from the return water pipe into the treatment pipe, the water is introduced from the treatment pipe into the return pipe, and then the water is guided back into the return pipe.

[0023] Preferably, the internal thread of the treatment pipe is connected to a filter plate one for coarse filtration of the return water. The end of the filter plate one away from the return water pipe is fixed with a plurality of connecting posts arranged in a ring. The end of the connecting posts away from the filter plate one is fixed with an activated carbon plate for adsorbing the return water. The surface of the activated carbon plate away from the filter plate one is fixed with a filter plate two for fine filtration of the return water through the connecting posts. The filter plate two is threaded to the inner wall of the treatment pipe.

[0024] By adopting the above technical solution, during the process of water flowing in the treatment pipe, the water undergoes three stages of filtration in sequence through filter plate one, activated carbon plate, and filter plate two: coarse filtration, adsorption, and fine filtration. This prevents impurities in the return water from clogging the return pipe and causing the return water to fail.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The drip irrigation system delivers water directly to the roots of tea seedlings, reducing ineffective water evaporation; the mist irrigation system regulates the air humidity in the seedling cultivation area, and both systems work on the seedling area to create a stable and suitable microenvironment for the seedlings, improving survival rate and growth quality. At the same time, the water return component filters excess water in three stages and recycles it for reuse, significantly reducing water waste and combining water conservation with irrigation, thus greatly improving the recycling rate of water resources.

[0027] 2. The height of the atomizing nozzle can be flexibly adjusted by adjusting the tube and positioning rod to ensure that the water mist covers the seedling area. The drip irrigation tube can be rotated 180 degrees by rotating the rotating block, and then limited by the limiting block after rotation, so that the drip tube will not rotate on its own without external force, avoiding interference with the seedling cultivation process and ensuring that the seedlings are not affected during cultivation.

[0057] The following is in conjunction with the appendix Figures 1-12 This application will be described in further detail.

[0058] This application discloses an irrigation device for tea seedling cultivation.

[0059] Reference Figure 1 A tea seedling cultivation irrigation device includes a water tank 1, which includes a door and a cover. The cover and the tank body are connected by a snap-fit ​​seal. A drain pipe 11 is fixed on one side of the surface of the water tank 1. A water pump and a booster pump are installed inside the water tank 1. The outlet of the water pump is connected to the drain pipe 11, so that the water pump can deliver water through the drain pipe 11. The water pump is an existing and mature technology. The principle of the water pump will not be described in detail. A water guide pipe 12 is fixed at the end of the drain pipe 11 away from the water tank 1.

[0060] Water is pumped from inside the water tank 1 to the outlet pipe 11, and then from the outlet pipe 11 to the water guide pipe 12, thus completing the water outflow.

[0061] Reference Figure 4 A cultivation seat 4 is provided on one side of the water tank 1 near the outlet pipe 11. A mounting frame 43 is fixed on one side of the surface of the cultivation seat 4. A return water plate 42 is fixed on one side of the surface of the cultivation seat 4 near the mounting frame 43. Multiple cultivation seats 422 for cultivating tea seedlings are fixed on one side of the surface of the return water plate 42.

[0062] The tea seedlings are cultivated by the cultivation seat 422, so that the tea seedlings can be neatly arranged on one side of the surface of the water return plate 42, preventing the individual tea seedlings from interfering with each other during their growth.

[0063] Reference Figures 1-9A misting irrigation mechanism 2 for misting irrigation of tea seedlings is provided on the side of the water pipe 12 near the cultivation base 4. The misting irrigation mechanism 2 includes a water inlet pipe 21 fixed to the surface of the water pipe 12, a solenoid valve 211 fixed to the end of the water inlet pipe 21 away from the water pipe 12, and a water outlet pipe 212 fixed to the end of the solenoid valve 211 away from the water inlet pipe 21. A conduit 213 is fixed to the surface of the water outlet pipe 212 away from the solenoid valve 211. The conduit 213 is located away from the water outlet pipe 212. One end of tube 212 is fixed with a T-shaped tube 214. The end of the T-shaped tube 214 away from the conduit 213 passes through the side of the mounting frame 43 away from the culture base 4. The T-shaped tubes 214 are arranged in a rectangle on the side of the mounting frame 43 away from the culture base 4. Every two T-shaped tubes 214 are connected by a connecting tube 22. The two T-shaped tubes 214 are connected by the connecting tube 22, and the connecting tube 22 is fixed to the T-shaped tube 214. The end of the T-shaped tube 214 near the culture base 4 is provided with an atomizing nozzle 23 for spraying water.

[0064] It should be noted that the water inlet pipe 12, water outlet pipe 21, solenoid valve 211, water outlet pipe 212, conduit pipe 213, and T-shaped pipe 214 are connected, and the diameters of the water outlet pipe 212, conduit pipe 213, and T-shaped pipe 214 decrease sequentially. Therefore, the diameter of the water outlet pipe 212 is greater than the diameter of the conduit pipe 213, and the diameter of the conduit pipe 213 is greater than the diameter of the T-shaped pipe 214, so that the water in the water outlet pipe 212 is sufficient to supply water to multiple conduits 213, thereby achieving water diversion.

[0065] The connection between the water inlet pipe 21 and the water outlet pipe 212 is controlled by solenoid valve 211. When solenoid valve 211 is closed, the water inlet pipe 21 and the water outlet pipe 212 are in a closed state. When solenoid valve 211 is open, the water inlet pipe 21 and the water outlet pipe 212 are in an open state.

[0066] Water is supplied to the water inlet pipe 21 through the water pipe 12. Water flows from the water pipe 12 into the water inlet pipe 21. Water from the water inlet pipe 21 is introduced into the water outlet pipe 212 through the solenoid valve 211. Water from the water outlet pipe 212 is introduced into the conduit pipe 213. Water from the conduit pipe 213 is introduced into the T-shaped pipe 214. Water is sprayed out from the atomizing nozzle 23 to irrigate the tea seedlings.

[0067] Reference Figures 1-9An adjusting tube 231 is fixed at one end of the atomizing nozzle 23 near the T-shaped tube 214. The surface of the adjusting tube 231 abuts against the inner wall of the T-shaped tube 214, allowing the adjusting tube 231 to slide stably inside the T-shaped tube 214. A driving block 24 is provided on one side of the surface of the T-shaped tube 214. A positioning rod 241 is fixed in the middle of the side of the driving block 24 near the surface of the T-shaped tube 214. A plurality of positioning holes 232 are opened on the surface of the adjusting tube 231, which are adapted to the end of the positioning rod 241 away from the driving block 24. The positioning rod 241 passes through the side of the T-shaped tube 214 near the driving block 24. A limiting plate 242 is fixed on the surface of the end of the positioning rod 241 away from the driving block 24. A limiting space 25 adapted to the limiting plate 242 is opened on the side of the T-shaped tube 214 near the driving block 24. The surface of the limiting plate 242 abuts against the inner wall of the limiting space 25, allowing the limiting plate 242 to slide stably inside the limiting space 25.

[0068] A protrusion 243 is fixedly provided on the middle of both sides of the surface of the limiting plate 242. The inner wall of the limiting space 25 is provided with a sliding groove 251 that matches the protrusion 243. The surface of the protrusion 243 abuts against the inner wall of the sliding groove 251, so that the protrusion 243 can slide stably inside the sliding groove 251. A spring 244 is fixedly provided on the middle of the side of the protrusion 243 near the driving block 24. The end of the spring 244 away from the protrusion 243 is fixed to the side wall of the sliding groove 251.

[0069] It should be noted that the calculation formula for spring 244 is: F=kx, where F is the external force on spring 244, in N, k is the spring constant of spring 244, in N / m, and x is the deformation of spring 244, in m. The elastic force of spring 244 is then calculated so that it can be used in this application.

[0070] The distance between the two positioning holes 232 is used to control the movement distance of the adjusting tube 231, thereby controlling the adjustment height of the atomizing nozzle 23.

[0071] By pulling the drive block 24 away from the surface of the T-shaped tube 214, the drive block 24 provides power to the positioning rod 241, causing the positioning rod 241 to gradually move away from the adjusting tube 231. As a result, the end of the positioning rod 241 away from the drive block 24 gradually disengages from the interior of the positioning hole 232. After the end of the positioning rod 241 away from the drive block 24 is completely disengaged from the interior of the positioning hole 232, the positioning rod 241 releases its positioning of the adjusting tube 231, allowing the adjusting tube 231 to slide inside the T-shaped tube 214. At this time, the atomizing nozzle 23 is pulled down, causing the atomizing nozzle 23 to drive the adjusting tube 231 to move downward, thereby adjusting the height of the atomizing nozzle 23.

[0072] During the sliding process, the positioning rod 241 drives the limiting plate 242 to move closer to the driving block 24. The limiting plate 242 drives the protrusion 243 to move closer to the driving block 24. The protrusion 243 presses the spring 244, causing the spring 244 to deform. During the process of pulling the atomizing nozzle 23, the driving block 24 needs to be released, so that the positioning rod 241 loses its tension, the limiting plate 242 loses its power from the positioning rod 241, and the protrusion 243 loses its power from the limiting plate 242. The protrusion 243 no longer presses the spring 244, and the spring 244 recovers its deformation. The protrusion 243 moves away from the driving block 24 with the elastic force of the spring 244 recovering its deformation. The protrusion 243 drives the limiting plate 242 away from the driving block 24. The limiting plate 242 drives the positioning rod 241 to move closer to the adjusting tube 231, so that the movement of the positioning rod 241 away from the driving block 24 abuts against the surface of the adjusting tube 231.

[0073] During the downward movement of the adjusting tube 231, when the positioning hole 232 moves to be directly opposite the end of the positioning rod 241 away from the drive block 24, the positioning rod 241 is re-inserted into the positioning hole 232 by the elastic force of the spring 244, positioning the adjusting tube 231 and fixing the adjusting tube 231 inside the T-shaped tube 214, thereby automatically fixing it after the height of the atomizing nozzle 23 is adjusted, ensuring the stability of the height adjustment.

[0074] Reference Figures 1-12 A drip irrigation mechanism 3 for drip irrigation is provided on the side of the water guide pipe 12 near the culture base 4. The drip irrigation mechanism 3 includes a second water inlet pipe 31 fixed to the surface of the water guide pipe 12. A second solenoid valve 311 is fixed at the end of the second water inlet pipe 31 away from the water guide pipe 12. A second water outlet pipe 312 is fixed at the end of the second solenoid valve 311 away from the second water inlet pipe 31. A second conduit 313 is fixed to the surface of the second water outlet pipe 312. A second water delivery pipe 314 is provided at the end of the second conduit 313 away from the second water outlet pipe 312. An installation ring 33 is fixed to the surface of the end of the second water delivery pipe 314 near the second conduit 313. The second conduit 313 has an installation groove 34 that matches the installation ring 33 at one end near the water supply pipe 314. The surface of the installation ring 33 abuts against the inner wall of the installation groove 34. A sealing ring 331 for sealing the connection between the second conduit 313 and the installation ring 33 is fixed on the surface of the installation ring 33. An annular groove 341 that matches the sealing ring 331 is opened on the inner wall of the installation groove 34. The surface of the sealing ring 331 abuts against the inner wall of the annular groove 341. A plurality of drip tubes 315 for dripping water are fixed on one side of the surface of the water supply pipe 314. The drip tubes 315 are set at a 45-degree angle on the surface of the water supply pipe 314.

[0075] It should be noted that: the water inlet pipe 12, the water inlet pipe 2 31, the solenoid valve 2 311, the water outlet pipe 2 312, the conduit pipe 2 313, the water supply pipe 314, and the drip pipe 315 are connected to each other, and the diameters of the water outlet pipe 2 312, the conduit pipe 2 313, the water supply pipe 314, and the drip pipe 315 decrease sequentially. Therefore, the diameter of the water outlet pipe 2 312 is greater than the diameter of the conduit pipe 2 313, the diameter of the conduit pipe 2 313 is greater than the diameter of the water supply pipe 314, and the diameter of the water supply pipe 314 is greater than the diameter of the drip pipe 315, so that the water in the water outlet pipe 2 312 is sufficient to supply water to multiple conduits 2 313, thereby achieving water diversion.

[0076] The connection between the water inlet pipe 31 and the water outlet pipe 312 is controlled by the solenoid valve 311. When the solenoid valve 311 is closed, the water inlet pipe 31 and the water outlet pipe 312 are in a closed state. When the solenoid valve 311 is open, the water inlet pipe 31 and the water outlet pipe 312 are in an open state.

[0077] Water is supplied to the second water inlet pipe 31 through the water guide pipe 12. Water flows from the water guide pipe 12 into the second water inlet pipe 31. Water is then introduced from the second water inlet pipe 31 into the second water outlet pipe 312 through the second solenoid valve 311. Water is then introduced from the second water outlet pipe 312 into the second conduit pipe 313. Water is then introduced from the second conduit pipe 313 into the water delivery pipe 314. Water is then introduced from the water delivery pipe 314 into the drip pipe 315. Water drips from the end of the drip pipe 315 away from the water delivery pipe 314 onto the roots of the seedlings, thus providing drip irrigation for the seedlings.

[0078] Reference Figures 1-6 A rotating shaft 32 is fixed at the end of the water supply pipe 314 away from the water guide pipe 12. The surface of the rotating shaft 32 is rotatably connected to the side wall of the mounting bracket 43 via a bearing. The bearing includes an inner ring, an outer ring, rolling elements, and a cage. The bearing is an existing and mature technology, and the principle of the bearing will not be described in detail. The outer ring of the bearing on the surface of the rotating shaft 32 is fixed to the side wall of the mounting bracket 43. A limiting block 321 is fixed to the surface of the rotating shaft 32. A rotating block 322 is fixed at the end of the rotating shaft 32 away from the water supply pipe 314. A limiting seat 431 that abuts against the limiting block 321 is fixed on the side of the mounting bracket 43 near the surface of the rotating block 322. A limiting block 321 for limiting the water supply pipe 314 is provided at the end of the water supply pipe 314 away from the water guide pipe 12.

[0079] Rotating block 322 provides power to rotating shaft 32, causing rotating shaft 32 to rotate. Rotating shaft 32 drives water pipe 314 to rotate, and water pipe 314 drives drip tube 315 to rotate, causing drip tube 315 to rotate 180 degrees. This prevents drip tube 315 from interfering with seedling cultivation. After rotation, the drip tube 315's own weight and the support of limiting seat 431 prevent water pipe 314 from rotating on its own without external force.

[0080] Reference Figures 1-4The surface of the water return plate 42 is provided with a water return hole 421 for water return, and the cultivation seat 422 is also provided with a water return hole 421 on the side of the surface near the water return plate 42. The inside of the cultivation seat 4 is provided with a water return cavity 41 that communicates with the water return hole 421. The bottom wall of the water return cavity 41 is inclined at an angle of 5-10°.

[0081] Excess water or water mist that was not sprayed on the seedling area is collected into the water return chamber 41 through the water return hole 421, thereby reducing water resource loss.

[0082] Reference Figures 1-9 The side wall of the return water chamber 41 is provided with a return water assembly 5 for returning water. The return water assembly 5 includes a return water pipe 51 fixed to the side wall of the return water chamber 41. The return water pipe 51 is located at the lower end of the inclined bottom wall of the return water chamber 41. A processing tube 52 is inserted into the end of the return water pipe 51 away from the culture base 4. A sealing ring 511 is fixed to the end of the return water pipe 51 away from the culture base 4. A sealing groove 521 is symmetrically opened inside the processing tube 52. The surface of the sealing ring 511 abuts against the inner wall of the sealing groove 521, so that... A sealing ring 511 seals the return pipe 51 and the treatment pipe 52. A guide pipe 57 is inserted into the end of the treatment pipe 52 away from the return pipe 51. The end of the guide pipe 57 away from the treatment pipe 52 is fixed to one side of the surface of the water tank 1, so that the guide pipe 57 is connected to the water tank 1. A sealing ring 571 is fixed at the end of the guide pipe 57 near the treatment pipe 52. The surface of the sealing ring 571 abuts against the inner wall of the sealing groove 521, so that the sealing ring 571 can seal the guide pipe 57 and the treatment pipe 52.

[0083] The internal thread of the treatment pipe 52 is connected to a filter plate 53 for coarse filtration of the return water. At the end of the filter plate 53 away from the return water pipe 51, a plurality of connecting posts 54 arranged in a ring are fixed. At the end of the connecting posts 54 away from the filter plate 53, an activated carbon plate 55 for adsorbing the return water is fixed. On the side of the activated carbon plate 55 away from the filter plate 53, a filter plate 56 for fine filtration of the return water is fixed through the connecting posts 54. The filter plate 56 is threaded to the inner wall of the treatment pipe 52. The pore diameter of the filter plate 53 is larger than that of the filter plate 56.

[0084] As water flows through the treatment pipe 52, it undergoes three stages of filtration: coarse filtration, adsorption, and fine filtration, through filter plate 53, activated carbon plate 55, and filter plate 56. This prevents impurities in the return water from clogging the return pipe 57 and causing return water failure. At the same time, the filter plate 53, activated carbon plate 55, and filter plate 56 in the treatment pipe 52 can be quickly replaced through threaded and plug-in connections, thereby ensuring the filtration quality of the return water.

[0085] Reference Figures 1-9 An air humidity sensor 6 is fixedly installed in the middle of the inner wall of the mounting bracket 43, and a soil humidity sensor is installed inside the cultivation base 422.

[0086] It should be noted that: the user needs to install relay module one and controller module one on one side of the surface of mounting bracket 43, connect air humidity sensor 6 to controller module one, connect controller module one to relay module one, connect relay module one to solenoid valve 211, and connect air humidity sensor 6, controller module one, relay module one, and solenoid valve 211 to the power supply.

[0087] When the air humidity sensor 6 detects that the air humidity is below 50%, it transmits a low humidity signal to the controller module 1. After logical judgment, the controller module 1 sends a high-level signal to the drive circuit of the solenoid valve 211. The relay module 1 then activates, opening the solenoid valve 211. High-pressure water flows through the atomizing nozzle 23 to form a water mist, increasing the air humidity. When the air humidity rises back to 70%, the controller module 1 sends a low-level signal to close the solenoid valve 211, preventing excessively high air humidity from causing damage.

[0088] The user needs to install relay module 2 and controller module 2 on both sides of the surface of mounting bracket 43, connect the soil moisture sensor to controller module 2, connect controller module 2 to relay module 2, connect relay module 2 to solenoid valve 311, and connect the soil moisture sensor, controller module 2, relay module 2, and solenoid valve 311 to the power supply.

[0089] When the soil moisture sensor detects that the soil moisture is below the lower limit (40%), it transmits a signal to controller module two. After logical judgment, controller module two sends a high-level signal to the solenoid valve 311 drive circuit of the drip irrigation branch. Relay module two is activated, opening solenoid valve 311 to replenish water to the seedling roots. As drip irrigation proceeds, the soil moisture increases. When the sensor detects that the moisture reaches the appropriate upper limit (60%), controller module two outputs a low level, closes solenoid valve 311, stops drip irrigation, and maintains the soil moisture within a reasonable range.

[0090] It should be noted that: the outlet pipe 11, water guide pipe 12, regulating pipe 231, drip pipe 315, return water pipe 51, and treatment pipe 52 are made of polyvinyl chloride (PVC); the first water inlet pipe 21, the first water outlet pipe 212, the first conduit pipe 213, the T-shaped pipe 214, and the connecting pipe 22 are all made of ABS; the second water inlet pipe 31, the second water outlet pipe 312, the second conduit pipe 313, and the water delivery pipe 314 are made of polyethylene (PE); the sealing ring 331 is made of nitrile rubber; the first sealing ring 511 and the second sealing ring 571 are made of silicone; and the inner wall of the cultivation base 422 is provided with a rubber layer.

[0091] Solenoid valve 1 (211) and solenoid valve 2 (311) are of the 12VDC series, air humidity sensor 6 is of the RHT30 series, and soil humidity sensor is of the SM150 series.

[0092] Users need to install a pressure compensation valve between the outlet pipe 11 and the water pump. When the water level in the water tank 1 changes, causing fluctuations in the outlet pressure (such as the water level dropping from 80% to 20%), the compensation valve will automatically adjust its opening to stabilize the outlet pressure at 0.15-0.2MPa, ensuring the operational stability of the drip irrigation and atomization systems.

[0093] The user installs a 1500L / h booster pump inside the water tank 1 and connects the inlet of the booster pump to the end of the return pipe 57 near the water tank 1, so that the return pipe 57 can accelerate the return water speed through the booster pump.

[0094] Before cultivation, the user opens the lid of water tank 1 and fills it with water. After the tank is full, the lid is closed again. This process is existing technology and will not be described in detail here.

[0095] The implementation principle of the irrigation device for tea seedling cultivation in this application embodiment is as follows: Before planting the tea seedlings inside the cultivation seat 422, the rotating block 322 needs to be rotated in a direction away from the cultivation seat 422 to provide power to the rotating shaft 32, so that the rotating shaft 32 rotates. The rotating shaft 32 drives the water supply pipe 314 to rotate, and the water supply pipe 314 drives the drip tube 315 to rotate, so that the drip tube 315 is rotated 180 degrees, so that the drip tube 315 is away from the cultivation seat 422, preventing the drip tube 315 from interfering with the seedling cultivation process. After the rotation, the water supply pipe 314 will not rotate on its own without being subjected to external force due to the weight of the drip tube 315 and the support of the limiting seat 431.

[0096] The seedlings are then planted inside the cultivation base 422 using a shovel or other tools. The cultivation process is existing technology, and the cultivation principle will not be described in detail.

[0097] After cultivation, by pulling the drive block 24 away from the surface of the T-shaped tube 214, the drive block 24 provides power to the positioning rod 241, causing the positioning rod 241 to gradually move away from the adjusting tube 231. This causes the end of the positioning rod 241 away from the drive block 24 to gradually disengage from the interior of the positioning hole 232. After the end of the positioning rod 241 away from the drive block 24 is completely disengaged from the interior of the positioning hole 232, the positioning rod 241 releases its positioning of the adjusting tube 231, allowing the adjusting tube 231 to slide inside the T-shaped tube 214. At this time, the atomizing nozzle 23 is pulled down, causing the atomizing nozzle 23 to drive the adjusting tube 231 to move downward, thereby adjusting the height of the atomizing nozzle 23.

[0098] During the sliding process, the positioning rod 241 drives the limiting plate 242 to move closer to the driving block 24. The limiting plate 242 drives the protrusion 243 to move closer to the driving block 24. The protrusion 243 presses against the spring 244, causing the spring 244 to deform. During the pulling of the atomizing nozzle 23, the driving block 24 needs to be released, so that the positioning rod 241 loses its tension, the limiting plate 242 loses its power from the positioning rod 241, and the protrusion 243 loses its power from the limiting plate 242. The protrusion 243 no longer presses against the spring 244, the spring 244 recovers its deformation, and the protrusion 243 moves away from the driving block 24 with the help of the elastic force of the spring 244 recovering its deformation. The protrusion 243 drives the limiting plate 242 away from the driving block 24. The limiting plate 242 drives the positioning rod 241 to move closer to the adjusting tube 231, so that the movement of the positioning rod 241 away from the driving block 24 abuts against the surface of the adjusting tube 231. During the downward movement of the adjusting tube 231, when the positioning hole 232 moves to be directly opposite the end of the positioning rod 241 away from the driving block 24, the positioning rod 241 is re-inserted into the positioning hole 232 by the elastic force of the spring 244, positioning the adjusting tube 231 and fixing the adjusting tube 231 inside the T-shaped tube 214. Thus, it is automatically fixed after the height of the atomizing nozzle 23 is adjusted, ensuring the stability of the height adjustment.

[0099] When the air humidity sensor 6 detects that the air humidity is below 50%, it transmits a low humidity signal to the controller module 1. After logical judgment, the controller module 1 sends a high-level signal to the drive circuit of the solenoid valve 211. The relay module 1 then activates, opening the solenoid valve 211. High-pressure water flows through the atomizing nozzle 23 to form a water mist, increasing the air humidity. Water is introduced from the inlet pipe 21 through the solenoid valve 211 into the outlet pipe 212. Water is then introduced from the outlet pipe 212 into the conduit 213. Water is then introduced from the conduit 213 into the T-shaped pipe 214. Finally, water is sprayed out from the atomizing nozzle 23 to irrigate the tea seedlings.

[0100] When the air humidity rises to 70%, the controller module sends a low-level signal to close the solenoid valve 211, preventing excessive air humidity from causing damage.

[0101] When the soil moisture sensor detects that the soil moisture is below the lower limit (40%), it transmits a signal to controller module two. After logical judgment, controller module two sends a high-level signal to the solenoid valve 311 drive circuit of the drip irrigation branch. Relay module two is activated, opening solenoid valve 311. Water flows from the inlet pipe 31 through solenoid valve 311 into outlet pipe 312. Water flows from outlet pipe 312 into conduit pipe 313. Water flows from conduit pipe 313 into delivery pipe 314. Water flows from delivery pipe 314 into drip tube 315. Water drips from the end of drip tube 315 away from delivery pipe 314 onto the roots of the seedlings, thus providing drip irrigation to replenish the seedling roots.

[0102] As drip irrigation proceeds, soil moisture increases. When the soil moisture sensor detects that the moisture has reached the appropriate upper limit (60%), the controller module 2 outputs a low level, closes the solenoid valve 311, stops drip irrigation, and maintains the soil moisture within a reasonable range.

[0103] Excess water or water mist not sprayed on the seedling area is collected in the return water chamber 41 through the return water hole 421. Then, the water is introduced into the return water pipe 51 through the inclined surface of the bottom wall of the return water chamber 41. The water is then introduced into the treatment pipe 52 from the return water pipe 51. During the flow of the water in the treatment pipe 52, the water undergoes three stages of filtration in sequence through the filter plate 53, the activated carbon plate 55, and the filter plate 56: coarse filtration, adsorption, and fine filtration. This prevents impurities in the return water from clogging the return pipe 57 and causing the return water to fail. The filtered water is then returned to the water tank 1 through the return pipe 57, thereby saving water resources for irrigating tea seedlings and greatly improving the water resource recycling rate.

[0104] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
