DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the present invention, the present invention is further clearly and completely described below in conjunction with reference to the accompanying drawings and embodiments.

[0021] refer to Figure 1-Figure 12 The present invention provides a technical solution of a water-saving irrigation device with a filtering function, comprising a seedling raising structure 1, the seedling raising structure 1 comprising a platform 11 and a plurality of seedling raising boxes 13, a flow guide box 12 is fixedly sleeved on the outer bottom of the plurality of seedling raising boxes 13, a plurality of filter screens 15 are arranged between the flow guide box 12 and the seedling raising boxes 13, a flow guide elbow 17 is fixedly connected to the bottom of one side of the flow guide box 12, atomizing nozzles 3 are arranged on the tops of the plurality of seedling raising boxes 13, a water-saving irrigation structure 2 is installed on the platform 11, and the water-saving irrigation structure 2 supplies water to the atomizing nozzles 3; the water-saving irrigation structure 2 comprises a water storage tank 21, an inner portion of the water storage tank 21 A partition component, a water pump 22, a three-way valve 25 connected to the output end of the water pump 22, a three-way valve 27 connected to the normally open end of the three-way valve 25, two diversion pipes 4 28 fixedly connected at both ends of the three-way valve 27, a booster component arranged between the two diversion pipes 4 28 and the water tank 21, and a water inlet control component arranged on the top of one side of the water tank 21, a diversion pipe 8 223 fixedly installed at the normally closed end of the three-way valve 25, a reflux component arranged between the diversion pipe 8 223 and the seedling raising structure 1 and the water tank 21; the bottom of the water tank 21 is connected to the water inlet end of the water pump 22 through a diversion pipe 23.

[0022] Specifically, a guide groove 1 216 is provided at the bottom of the inner cavity of the water storage tank 21, a guide pipe 1 23 is provided at the bottom of the guide groove 1 216, two ends of the guide pipe 1 23 are respectively fixedly connected to the water inlet end of the water pump 22 and the bottom of the water storage tank 21, a guide pipe 2 24 is fixedly connected between the water outlet end of the water pump 22 and the three-way valve 1 25, and a guide pipe 3 26 is fixedly connected between the normally open end of the three-way valve 1 25 and the three-way valve 27. When the three-way valve 1 25 is not in operation, the water pump 22 can pump water from the inside of the water storage tank 21 through the guide pipe 1 23 and the guide groove 1 216, and the water is transported by the water pump 22 to the inside of the three-way valve 27 through the guide pipe 2 24, the three-way valve 1 25 and the guide pipe 3 26. Since the partition plate 215 in the partition assembly divides the interior of the water tank 21 into a clean water chamber and a mixed water chamber, the clean water chamber is arranged on the side of the partition plate 215 away from the water pump 22, and the mixed water chamber is located on the side of the partition plate 215 close to the water pump 22; an electric push rod 214 is fixedly connected to one side of the partition plate 215, and two mounting brackets 213 are fixedly connected between the outer side of the electric push rod 214 and the water tank 21. When the electric push rod 214 is not working, the partition plate 215 is arranged on the top of the guide groove 216 close to the water pump 22. At this time, the guide pipe 23 is connected to the clean water chamber, such as Figure 8 shown.

[0023] A diversion pipe four 28 is fixedly connected to the normally open end and the normally closed end of the three-way valve two 27, and a diversion pipe five 29 is fixedly installed between the two diversion pipes four 28, and a one-way valve 210 is fixedly installed at both ends inside the diversion pipe five 29, and a pressure relief valve 212 is fixedly connected between one end of the diversion pipe six 211 fixedly connected to the outer bottom of the diversion pipe five 29 and the top of one side of the water tank 21, and the water entering the diversion pipe four 28 can enter the diversion pipe five 29 through the one-way valve 210, but the water inside the diversion pipe five 29 is blocked by the one-way valve 210 and cannot flow back into the diversion pipe four 28, and when the hydraulic pressure on one side of the pressure relief valve 212 reaches a certain level, the pressure relief valve 212 will be flushed open, and the hydraulic pressure inside the diversion pipe four 28 and the diversion pipe five 29 will be pressurized to a certain value.

[0024] When it is necessary to irrigate the nurseries inside the multiple seedling boxes 13, the water pump 22 is controlled to work for the first time. The working water pump 22 draws clean water from the clean water cavity through the diversion pipe 1 23, and the water pump 22 transports the clean water to the inside of the three-way valve 2 27 through the diversion pipe 2 24, the three-way valve 1 25 and the diversion pipe 3 26. The clean water enters the left diversion pipe 4 28 fixedly installed at the normally open end of the three-way valve 2 27. After the hydraulic pressure in the diversion pipe 4 28 rises to a certain value, since the tops of the multiple seedling boxes 13 are all provided with atomizing nozzles 3, the atomizing nozzles 3 are fixedly connected to the diversion pipe 4 28 on the same side, therefore, the three-way valve 2 27 is normally installed at the open end. During the hydraulic rising process inside the left diversion pipe four 28, water is atomized by multiple atomizing nozzles 3 fixedly installed on the left diversion pipe four 28 and then sprayed into the bottom seedling box 13, and the nurseries inside the multiple seedling boxes 13 on the left are irrigated; because the water supply speed of the water storage tank 21 to the left diversion pipe four 28 exceeds the drainage speed of the multiple seedling boxes 13, the drainage water pressure of the atomizing nozzle 3 is maintained inside the diversion pipe four 28 to ensure that the seedling box 13 discharges the atomized water stably and uniformly to irrigate the nursery inside the seedling box 13; after a period of time, the water pump 22 is controlled to stop working for the first time, the irrigation stops, and the nurseries inside the multiple seedling boxes 13 on the left are watered.

[0025] A plurality of drainage grooves 14 are provided at the outer bottom of the seedling box 13, and a plurality of filter screens 15 are respectively arranged inside the plurality of drainage grooves 14. A small hole 16 is provided on one side of the filter screen 15. The small hole 16 is provided on the guide box 12 fixedly mounted on the outer bottom of the seedling box 13, and the small hole 16 is provided at a position of the guide box 12 close to the seedling box 13. As the water inside the nursery increases, the water is filtered by the filter screen 15 and collected into the guide box 12 through the small hole 16, and a guide bend 17 fixedly connected to the guide box 12 is arranged at the bottom of one side of the guide box 12. The guide bend 17 leads the water collected into the guide box 12 as recycled water, and during the watering of the nursery inside the seedling box 13, the recycled water not absorbed by the soil is guided and discharged, so as to avoid the accumulation of water inside the seedling box 13, and the vertical arrangement of the filter screen 15 can reduce the amount of soil discharged along with the water flow, reduce the rot of plant roots, and reduce losses.

[0026] The nursery inside the seedling box 13 at the bottom of the left diversion pipe four 28 is irrigated, one end of the diversion elbow 17 arranged on one side of the multiple seedling boxes 13 all penetrate the platform 11, and the multiple diversion elbows 17 on the left are fixedly connected to the left diversion pipe seven 220 in the reflux assembly, and the multiple diversion elbows 17 on the right are fixedly connected to the right diversion pipe seven 220, one end of the two diversion pipes seven 220 are fixedly connected to the water storage tank 21 with a solenoid valve 221, the solenoid valve 221 is connected to one end of the water storage tank 21 close to the water pump 22, and the diversion pipe seven 220 is connected to the mixing water chamber through the solenoid valve 221, so the recovered water is collected and stored inside the mixing water chamber in the water storage tank 21.

[0027] After the water pump 22 stops working for the first time, the irrigation of the nursery inside the left multiple seedling boxes 13 is completed, and a period of time is waited to provide time for the recycled water inside the left multiple seedling boxes 13 that is not absorbed by the soil to be discharged.

[0028] Since the transmission shaft 222 inserted at the bottom of the guide pipe 8 223 is rotatably connected to the guide pipe 8 223, the sealing plate 224 fixedly connected to the outer top of the transmission shaft 222 is arranged at the bottom of the inner cavity of the guide pipe 8 223, guide grooves 225 are provided on both sides of the bottom of the guide pipe 8 223, and guide grooves 3 226 are provided on the tops of the two guide pipes 7 220, and the guide grooves 3 226 are aligned with the guide grooves 225 on the same side, so that the guide pipe 8 223 is connected to the inside of the two guide pipes 7 220; A transmission shaft 218 is connected, the bottom end of the transmission shaft 218 passes through the water tank 21 and is rotatably connected to the water tank 21, multiple blades 219 fixedly installed on the outside of the transmission shaft 218 are all arranged on the side of the water tank 21 close to the water pump 22, and the multiple blades 219 are all arranged inside the mixing water chamber, and a driving motor 217 is fixedly connected to the bottom end of the transmission shaft 218. Two vertical plates are fixedly connected between the driving motor 217 and the water tank 21, and the water tank 21 forms a transmission relationship with the sealing plate 224 through the transmission shaft 218 and the transmission shaft 222.

[0029] After a period of time, the electric push rod 214 is controlled to work and the electric push rod 214 works and contracts. The electric push rod 214 drives the fixedly connected partition plate 215 to move in the direction away from the water pump 22. When the electric push rod 214 stops working, the partition plate 215 moves to the top of the guide groove 216 away from the side of the water pump 22. At this time, the guide pipe 23 is connected to the inside of the mixing chamber through the guide groove 216.

[0030] The three-way valve 25 is controlled to work, the normally closed end of the three-way valve 25 is opened, and the driving motor 217 is controlled to work once. The driving motor 217 drives the transmission shaft 218 to rotate three 180°, and the transmission shaft 222 fixed by the transmission shaft 218 and the sealing plate 224 fixed by the transmission shaft 222 rotate three 180°. At this time, the sealing plate 224 rotates to the top of the left diversion pipe 7 220, and the sealing plate 224 blocks the diversion groove 225 at the top of the left diversion pipe 7 220. At this time, the inside of the diversion pipe 8 223 is only connected to the inside of the diversion pipe 7 220 on the right through the diversion groove 3 226 and the diversion groove 2 225 on the right; and the transmission shaft 1 218 rotates during the rotation process, and the multiple blades 219 are driven to rotate. The rotating blades 219 stir the recycled water inside the mixing chamber to avoid the situation where the substances dissolved in the water are separated and precipitated to the bottom of the inner cavity of the water storage tank 21 and cannot be used, thereby ensuring that the substances in the recycled water inside the mixing chamber are evenly distributed and the quality of the recycled water put into use is ensured.

[0031] Subsequently, the two solenoid valves 221 are controlled to work and enter a closed state, at which time the communication between the diversion pipe 7 220 and the water storage tank 21 is blocked.

[0032] Finally, the water pump 22 is controlled to work. At this time, after the water pump 22 extracts the recycled water inside the mixing chamber through the diversion pipe 23 and the diversion groove 216, the water pump 22 transports the recycled water through the diversion pipe 2 24, the normally closed end of the three-way valve 25, the diversion pipe 8 223, the right diversion groove 3 226, and the right diversion groove 2 225 to the inside of the right diversion pipe 7 220. The diversion pipe 7 220 is fixedly connected with the multiple diversion elbows 17 on the right side. The recycled water is transported to the inside of the multiple diversion boxes 12 on the right side through the right diversion pipe 7 220 and the multiple diversion elbows 17. The water returns to the inside of the seedling box 13 through the multiple small holes 16 and the multiple filter nets 15 opened on the outside of the diversion box 12, and irrigates from the bottom of the nursery inside the multiple seedling boxes 13 to prevent the recycled water containing substances in the soil from directly acting on the leaves of plants in the nursery.

[0033] In the present embodiment, the water-saving irrigation structure 2 divides the multiple seedling boxes 13 supported on the top of a platform 11 into two rows on the left and the right. When the multiple seedling boxes 13 on the left are irrigated, they are irrigated from top to bottom by atomizing clean water. During the irrigating of the multiple seedling boxes 13 on the left, the water that is not absorbed by the soil in the seedling boxes 13 is collected to form recycled water, and the recycled water containing substances in the nursery soil is quickly put into use, thereby reducing the loss of nutrients, reducing the water resources used for irrigating multiple seedling boxes 13 at one time, and reducing the waste of water resources.

[0034] Similarly, when the irrigation works next time, the normally closed end of the three-way valve 27 can be controlled to open, and the water pump 22 can work to extract the clean water in the clean water chamber. The clean water enters the right-side diversion pipe 28 and is sprayed through multiple atomizing nozzles 3 at its bottom to irrigate multiple seedling boxes 13 on the right side; after a period of time, the water pump 22 is controlled to stop working; after waiting for a period of time, the electric push rod 1 214 is controlled to work and retract. After the partition plate 215 moves, the water pump 22 is connected to the mixing water chamber through the diversion pipe 1 23, and the driving motor 217 is controlled to work to drive the sealing plate 224 to rotate three 180 degrees, so that the sealing plate 224 is facing the right side. The guide groove two 225 and the guide groove three 226 at the top of the guide pipe seven 220 are sealed, so that the interior of the guide pipe eight 223 is connected with the left guide pipe seven 220; then the normally closed end of the three-way valve one 25 is controlled to open, and the water pump 22 is controlled to work. At this time, the water pump 22 extracts the recycled water from the mixing chamber and transports it to the left guide pipe seven 220 through the guide pipe two 24, the three-way valve one 25 and the guide pipe eight 223. The guide pipe seven 220 transports the recycled water to the inside of the multiple guide boxes 12 on the left through the multiple guide bends 17 on the left, and finally the recycled water enters the inside of the multiple seedling boxes 13 on the left, completing one irrigation.

[0035] In addition, if Figure 8As shown, a liquid level sensor 4 is fixedly connected to the top of the inner cavity of the water storage tank 21. The liquid level sensor 4 is arranged inside the mixing water cavity. The liquid level sensor 4 detects the height of the liquid level of the recovered water inside the mixing water cavity. During the process of the water pump 22 extracting the recovered water inside the mixing water cavity, when the liquid level sensor 4 detects that the height of the liquid level inside the mixing water cavity is lower than the preset height, and the working time of the water pump 22 is longer than the minimum working time of the water pump 22, the water pump 22 stops working and completes one irrigation work.

[0036] In addition, if Figure 8 , Fig.11 and Fig.12 As shown, the guide groove four 227 in the water inlet control assembly is arranged on the side of the partition plate 215 away from the water pump 22, and the guide groove four 227 is connected to the clean water chamber. The guide groove five 228 is arranged on the side of the partition plate 215 close to the water pump 22, and the guide groove five 228 is connected to the mixing water chamber. The guide groove four 227 and the guide groove five 228 are both formed on the top of one side of the water tank 21.

[0037] A water diversion pipe 229 is arranged on one side of the guide groove four 227. The water diversion pipe 229 is fixedly connected to the water storage tank 21. The water diversion pipe 229 is connected to the water supply system. When the water pump 22 works to extract clean water from the clean water chamber, the water supply system simultaneously fills water into the water diversion pipe 229 and the clean water chamber. A certain amount of clean water is always stored in the water storage tank 21 to ensure that the irrigation needs of multiple seedling boxes 13 can be met in the event of a failure of the water supply system.

[0038] A water diversion box 232 is provided on one side of the guide groove five 228, and the water diversion box 232 is fixedly connected to the water storage tank 21. The bottom of the water diversion pipe one 229 is fixedly connected to a diversion box 230, and an electric push rod two 237 and a telescopic tube 238 are fixedly connected inside the diversion box 230. A sealing block 235 is fixedly connected to the top of the electric push rod two 237.

[0039] When the water pump 22 extracts recycled water from the mixing water chamber for irrigation, the liquid level sensor 4 detects that the liquid level height inside the mixing water chamber is lower than the preset height, and the working time of the water pump 22 is lower than the preset minimum working time, the electric push rod 237 is controlled to work, and the electric push rod 237 pushes the sealing block 235 to move up, and the sealing block 235 separates the inside of the water diversion pipe 1 229.
