DETAILED DESCRIPTION

[0025] Example 1, as Figures 1-8 As shown, the present embodiment proposes an integrated intelligent irrigation and seedling raising device for soilless cultivation of agricultural vegetables, which includes a frame 12, a soilless cultivation mechanism, a water supply mechanism and a blocking component.

[0026] The soilless cultivation mechanism is arranged in multiple groups in an array both vertically and horizontally on the frame 12. The soilless cultivation mechanism includes an irrigation pool 1, a cultivation plate 2 placed on top of the irrigation pool 1, and multiple irrigation mechanisms arranged in a horizontal array. The cultivation plate 2 has multiple cultivation holes 201, each of which is provided with a cultivation cup 202. The cultivation holes 201 are stepped holes, and the cultivation cup 202 is a variable diameter cup. The upper outer diameter of the cultivation cup 202 is larger than the lower outer diameter, allowing it to fit in the cultivation hole 201 and be easily removed. The lower portion of the cultivation cup 202 is evenly distributed with mesh holes, and vegetable seeds are embedded in the matrix within the cultivation cup 202 for seedling cultivation. The cultivation plate 2 has a raised plate portion in the middle that snaps into the top of the irrigation pool 1. Both sides of the plate extend to the outside of the irrigation pool 1 on both sides in the width direction, making it convenient to remove and place the cultivation plate 2. The irrigation mechanism includes a water delivery assembly that extends through and into the irrigation tank 1; a vertically sliding lift tube 10 mounted on top of the water delivery assembly; two spray heads 11 connected to either side of the lift tube 10; two outlet pipes 5 connected to either side of the upper portion of the water delivery assembly; and a removable drip irrigation assembly connected to the outlet pipe 5. When connected to the outlet pipe 5, the drip irrigation assembly is positioned around the lower portion of the cultivation cup 202, providing uniform drip irrigation and replenishing water into the cultivation cup 202. The lift tube 10 has a through hole 101. When raised to its maximum position, it blocks the connection between the outlet pipe 5 and the water delivery assembly, allowing the spray heads 11 to spray water mist for aeroponics. When the lifting tube 10 moves down to the extreme position, the through hole 101 is connected to the water outlet pipe 5, so that water is added to the irrigation pool 1 through the water outlet pipe 5 to realize hydroponics, or water is transported to the drip irrigation assembly through the water outlet pipe 5. The drip irrigation assembly is used to add water to the substrate during substrate cultivation. Water seeps from the substrate in the irrigation pool 1 to the substrate in the cultivation cup 202, which is beneficial to the seed seedling cultivation in the cultivation cup 202.

[0027] like Figure 5 As shown, the water delivery assembly includes a water delivery pipe 3 and a limiting cylinder 4 connected to the top of the water delivery pipe 3. The inner circumferences of the water delivery pipe 3 and the limiting cylinder 4 are both circular surfaces, and the inner diameter of the water delivery pipe 3 is smaller than the inner diameter of the limiting cylinder 4. The lifting pipe 10 is a stepped circular tubular structure with a lower diameter larger than an upper diameter, an open bottom end, and a closed top end. When the lifting pipe 10 moves down to the extreme position, the bottom end of the lifting pipe 10 contacts the top end of the water delivery pipe 3, and the water delivery pipe 3 can be blocked under the lifting pipe 10. The lower part of the lifting pipe 10 is located inside the limiting cylinder 4, and the upper part passes through the top end of the limiting cylinder 4. When the lifting pipe 10 moves up to the extreme position, the lower top end of the lifting pipe 10 contacts the inner top end of the limiting cylinder 4. The outer circumference of the lifting pipe 10 has vertically distributed ridges, and the limiting cylinder 4 has grooves for the ridges to slide, ensuring that the lifting pipe 10 can be lifted and lowered vertically.

[0028] like Figure 1 、 Figure 6 、 Figure 7 and Figure 8As shown, the water supply mechanism supplies water to the irrigation system. The water supply mechanism includes a water pump 27, a water tank assembly whose bottom end is connected to the output end of the water pump 27, a vent pipe 26 connected to the water tank assembly, a diverter pipe 13 connecting the water tank assembly to the water delivery assembly, and a valve 14 mounted on the diverter pipe 13. Each diverter pipe 13 is used to deliver water to multiple groups of water delivery assemblies at the same height. A mounting base 28 is provided at the bottom of the water pump 27 and the water tank assembly.

[0029] like Figure 1 As shown, the blocking assembly is used to control the opening and closing of the top end of the vent tube 26.

[0030] This irrigation and seedling raising device can meet the irrigation and water replenishment needs of three different types of soilless cultivation seedlings. Users can choose according to their needs. The usage of the three types of irrigation and water replenishment are as follows:

[0031] 1. When using this irrigation and seedling raising device for hydroponics, place the cultivation plate 2 on top of the irrigation pool 1, and place the cultivation cup 202 containing a built-in substrate and embedded seeds at the cultivation hole 201, with the cultivation cup 202 extending downward into the irrigation pool 1. Close valve 14, and pump 27 to pump water into the water tank assembly. Then, shut down pump 27 and open valve 14. The water in the water tank assembly automatically flows through the diverter pipe 13 to the water delivery assembly, flows through the through hole 101 to the outlet pipe 5, and is discharged into the irrigation pool 1 through the outlet pipe 5. When the water level rises to the level of the cultivation cup 202, it can seep through the mesh into the substrate inside the cultivation cup 202, replenishing water for the development of the seeds inside.

[0032] 2. When using this irrigation and seedling raising device for drip irrigation during substrate cultivation, connect the drip irrigation assembly to the outlet pipe 5, add substrate into the irrigation pool 1, reserve a placement groove for the cultivation cup 202 on the top of the substrate, place the cultivation plate 2 on the top of the irrigation pool 1, place the cultivation cup 202 with built-in substrate and buried seeds on the cultivation hole 201, extend the cultivation cup 202 downward into the substrate placement groove in the irrigation pool 1, and the drip irrigation assembly is located around the cultivation cup 202. Close the valve 14, pump water into the water tank assembly through the water pump 27, then shut down the water pump 27, open the valve 14, and the water in the water tank assembly automatically flows through the shunt pipe 13 to the water delivery assembly, flows through the through hole 101 to the water outlet pipe 5, and is delivered to the drip irrigation assembly through the water outlet pipe 5. The drip irrigation assembly seeps water into the matrix in the irrigation pool 1, and the water continues to seep into the interior of the cultivation cup 202 through the mesh on the cultivation cup 202, replenishing water for seed seedling cultivation, thereby realizing drip irrigation during matrix cultivation.

[0033] 3. When using this irrigation and seedling raising device for aeroponics, the cultivation plate 2 is placed on top of the irrigation pool 1, and the cultivation cup 202 with a built-in matrix and embedded seeds is placed at the cultivation hole 201, with the cultivation cup 202 extending downward into the irrigation pool 1. The valve 14 is closed, and water is pumped into the water tank assembly via the water pump 27. The water is then sealed at the top of the vent pipe 26 via the sealing assembly. The valve 14 is then opened, and the water pump 27 continues to pump water, pumping the water in the water tank assembly through the diverter pipe 13 to the water delivery assembly. The water lifts the lifting pipe 10 upward to its limit position, misaligning the through hole 101 with the water outlet pipe 5. The lifting pipe 10 is sealed at the connection between the water outlet pipe 5 and the limiting cylinder 4. Water is then transported to the spray head 11 through the spray head 11, and a water mist is sprayed from the spray head 11 toward the mesh of the cultivation cup 202. The water penetrates into the matrix inside the cultivation cup 202, replenishing water for seedling cultivation.

[0034] This embodiment can be used for uniform irrigation during matrix cultivation, and can also be used for water replenishment during hydroponics and aerosol cultivation. It has a wide range of applications and can meet the water replenishment and irrigation needs of different types of soilless vegetable seed seedling cultivation, which is beneficial to seedling cultivation. When performing hydroponics, water is directly added to the irrigation pool 1 through the outlet pipe 5. The water penetrates into the matrix in the cultivation cup 202 through the mesh to replenish water for seed cultivation. When performing aerosol cultivation, it is necessary to block the vent pipe 26, maintain the water pumping state through the water pump 27, and push the lifting pipe 10. The water pressure is relatively high and can be sprayed in a mist form through the spray head 11. The water penetrates into the matrix in the cultivation cup 202 through the mesh to replenish water for seed cultivation. When performing matrix cultivation, it is necessary to connect the drip irrigation assembly to the outlet pipe 5. Water automatically seeps out from the drip irrigation assembly into the matrix in the irrigation pool 1, and then continues to penetrate into the matrix with seeds buried inside the cultivation cup 202 through the mesh to replenish water for seed cultivation.

[0035] Example 2, as Figures 1-8 As shown, this embodiment proposes an integrated intelligent irrigation and seedling raising device for soilless cultivation of agricultural vegetables. Compared to the first embodiment, the drip irrigation assembly in this embodiment includes a baffle 9 rotatably mounted on the outer end of the outlet pipe 5, a rotating frame 8 mounted on the baffle 9, a connecting pipe 6 slidably mounted on the rotating frame 8, a dripping member 7 connected to the outer end of the connecting pipe 6, and a first retaining ring 61 and a second retaining ring 62 arranged side by side on the connecting pipe 6, with retaining rings 1 and 2 located on either side of the rotating frame 8. When the outlet pipe 5 is used to discharge water for hydroponics, the dripping member 7 is naturally placed. When the drip irrigation assembly is connected to the outlet pipe 5 for drip irrigation in substrate cultivation, the baffle 9 is flipped upward, which drives the rotating frame 8 to rotate, aligning and connecting the connecting pipe 6 with the outlet pipe 5. The dripping member 7 rotates to a horizontal position, correspondingly positioned below the cultivation hole 201. Water is then transported through the outlet pipe 5 and the connecting pipe 6 to the dripping member 7, and drip irrigation is performed using the dripping member 7.

[0036] The dripper 7 comprises multiple coaxially arranged annular tubes and a connecting tube that connects the multiple annular tubes. Both the annular tubes and the connecting tube have seepage holes at their bottoms. Once the cultivation cup 202 is in place, it passes through the innermost annular tube. Water flows from the connecting tube 6 into the dripper 7, seeping through the seepage holes at the bottoms of the annular tubes and the connecting tube. This allows for uniform drip irrigation, allowing water to seep through the mesh into the cultivation cup 202, replenishing water for seed development and facilitating seedling cultivation.

[0037] The outer end of the outlet pipe 5 has external threads, and the connecting pipe 6 has internal threads that match the external threads. When the drip irrigation assembly is not in use, the connecting pipe 6 and the dripping member 7 are naturally stacked, and the retaining ring 1 61 is blocked by the rotating frame 8. When the drip irrigation assembly is in use, the connecting pipe 6 is threadedly connected to the outlet pipe 5. Once connected, the retaining ring 2 62 is blocked by the rotating frame 8.

[0038] like Figure 2 and Figure 3 As shown, when the outlet pipe 5 and the connecting pipe 6 are connected, the baffle 9 blocks the spray head 11. On the one hand, the spray head 11 can position the rotation of the baffle 9. When the baffle 9 blocks the spray head 11, the dripping element 7 rotates to a horizontal position. On the other hand, the baffle 9 prevents water from being sprayed out of the spray head 11.

[0039] This embodiment can conveniently connect the drip irrigation assembly to the water outlet pipe 5 or remove it from the water outlet pipe 5 to carry out different types of irrigation, water replenishment and seedling cultivation.

[0040] Example 3, as Figures 1-8As shown, this embodiment proposes an integrated intelligent irrigation and seedling raising device for soilless cultivation of agricultural vegetables. Compared with the first embodiment, the water tank assembly in this embodiment includes a bottom tank 21, a top tank 22, and multiple connecting tanks 23 stacked between the bottom tank 21 and the top tank 22. The number of connecting tanks 23 is determined by the number of layers of the soilless cultivation mechanism, specifically two fewer than the number of layers of the soilless cultivation mechanism, to ensure that the bottom tank 21, the top tank 22, and the connecting tank 23 each correspond to one layer of the soilless cultivation mechanism. The bottoms of the connecting box 23 and the top box 22 both have insertion openings, and the tops of the bottom box 21 and the connecting box 23 both have convex cylinders 211 passing through the insertion openings. The top of the convex cylinder 211 has an arcuate surface, and a baffle 24 and a counterweight ball 25 are inserted into the convex cylinder 211. The baffle 24 is an inverted T-shaped rod structure, with the bottom end blocking the bottom of the convex cylinder 211. The counterweight ball 25 is connected to the top of the baffle 24 and can be sealed against the top of the convex cylinder 211 when it fits the arcuate surface. The outer surface of the counterweight ball 25 is made of rubber, and the interior is embedded with counterweight material. Its own gravity can overcome buoyancy and sink. There are multiple ventilation pipes 26, which are connected to the bottom of the bottom box 21, the top box 22 and the connecting box 23 one by one. The output end of the water pump 27 is connected to the bottom of the bottom box 21. The tops of the multiple ventilation pipes 26 are flush and all higher than the top of the top box 22. When the vent tubes 26 are unblocked, they maintain pressure balance with the outside air during drainage of the bottom tank 21, top tank 22, and connecting tank 23. Transparent vent tubes 26 allow users to visually observe the water level within the vent tubes 26 to determine the water levels within the bottom tank 21, top tank 22, and connecting tank 23. Each vent tube 26 can be secured to the water tank assembly using a fixing plate to ensure stability.

[0041] The blocking assembly includes a lifting mechanism 30 disposed on the top box 22 and a blocking platform 29 disposed at the movable end of the lifting mechanism 30. The blocking platform 29 is located above the vent pipe 26. The lifting mechanism 30 can be an electric push rod, an air cylinder, or an oil cylinder. The bottom of the blocking platform 29 has a plug that can be inserted into the interior of the vent pipe 26.

[0042] In this embodiment, in the three usage modes of hydroponics, mist cultivation and drip irrigation, in the process of pumping water into the water tank assembly by the water pump 27 and opening the valve 14, the water first enters the bottom box 21, and then pushes open the counterweight ball 25 at the convex cylinder part 211 from the top. The inverted T-shaped rod-shaped baffle 24 can limit the range of movement of the counterweight ball 25, and the water gradually fills the connecting box 23 adjacent to the bottom box 21. Similarly, the water sequentially fills the remaining connecting boxes 23 and the top box 22 above.

[0043] After the bottom tank 21, top tank 22, and connecting tank 23 are all filled, if hydroponics or drip irrigation is being used, the water pump 27 is shut down, the weighted ball 25 descends due to its own gravity and blocks the curved surface of the convex cylindrical portion 211. The valve 14 is opened, and the bottom tank 21, top tank 22, and connecting tank 23 each deliver water through the corresponding shunt pipes 13 without interfering with each other. The vent pipe 26 is used to maintain the connection between the bottom tank 21, top tank 22, and connecting tank 23 and the outside world, allowing water to be discharged smoothly through the shunt pipes 13. The water delivered to the water delivery assembly is insufficient to push the lifting pipe 10 upward, and the through hole 101 of the lifting pipe 10 remains connected to the water outlet pipe 5.

[0044] After the bottom tank 21, top tank 22, and connecting tank 23 are all filled with water, if aeroponics is being used, the top of the vent tube 26 is sealed with a sealing assembly, valve 14 is opened, and water pump 27 continues pumping water. The water in the bottom tank 21 is not only sprayed out through the corresponding spray nozzle 11, but also pushes the counterweight ball 25 upward to be transported to the adjacent connecting tank 23. Similarly, the water in each connecting tank 23 is not only sprayed out through the corresponding spray nozzle 11, but also transported upward, allowing the water in the top tank 22 to be sprayed out through the corresponding spray nozzle 11. Overall, aeroponics can be performed using spray nozzles 11 at different heights, replenishing water to the seed-embedded substrate inside the cultivation cup 202, which is beneficial for seedling cultivation.

[0045] Example 4, as Figures 1-8 As shown, this embodiment proposes an integrated intelligent irrigation and seedling raising device for soilless cultivation of agricultural vegetables. Compared to the first embodiment, in this embodiment, valve 14 comprises a valve housing, a valve plate rotatably disposed within the valve housing, and a rotating shaft rotatably disposed on the valve housing and connected to the valve plate. The frame 12 is provided with an adjustment assembly that adjusts the opening of valve 14 by adjusting the position of the rotating shaft. The adjustment assembly adjusts the range of the rotating shaft, thereby adjusting the position of the valve plate, achieving adjustment of the opening of valve 14, controlling the water flow rate, and thus the irrigation speed of hydroponics, aeroponics, and drip irrigation.

[0046] The adjustment assembly includes a motor 15 mounted on the frame 12, a screw rod 16 connected to the output end of the motor 15 and rotatably mounted on the frame 12, a movable platform 17 threadedly connected to the screw rod 16, a movable rod 18 mounted on the movable platform 17, a plurality of racks 19 arranged vertically side by side on the movable rod 18, and a gear 20 mounted on the rotating shaft, wherein the racks 19 are meshedly connected to the gears 20. The motor 15 can drive the screw rod 16 to rotate forward and reverse, which in turn drives the movable platform 17 to rise and fall. The movable platform 17 drives the racks 19 to rise and fall via the movable rod 18, which in turn drives the gears 20 to rotate. The gears 20 then drive the rotating shaft to rotate, thereby adjusting the valve plate position and synchronously regulating the opening of each valve 14 with a high degree of uniformity.

[0047] In this embodiment, the opening of each valve 14 is uniformly regulated by the regulating component, thereby uniformly regulating the water delivery speed of each diversion pipe 13, and controlling the irrigation speed during hydroponics, mist cultivation and drip irrigation.

[0048] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
