Description

Technical Field

[0001] The invention belongs to the technical field of irrigation equipment, and in particular relates to water-fertilizer integrated intelligent trace irrigation equipment. Background Art

[0002] In agricultural production, irrigation equipment is used to irrigate crops. Existing irrigation equipment can accurately control the amount of irrigation water and irrigation time according to the water requirements of different crops and soil moisture conditions, thereby improving the yield and quality of crops.

[0003] In the Chinese patent with the publication number CN217183876U, a water-fertilizer integrated intelligent trace irrigation device is mentioned, including a water-fertilizer integrated box and a trace irrigation mechanism. A feeding port is provided at the top of the water-fertilizer integrated box, and a water-fertilizer mixing mechanism is provided inside the water-fertilizer integrated box. The water-fertilizer mixing mechanism includes a net barrel, a top ring is provided at the top of the net barrel, and a convex ring is provided concentrically at the bottom of the top ring. A one-way limit component 1 is provided between the side wall of the feeding port and the convex ring, a stirring rod is provided on the inner wall of the bottom of the net barrel, and the stirring rod extends to the outer wall of the bottom of the net barrel. An outer ring is provided at the bottom of the water-fertilizer integrated box, and a one-way limit component 2 is provided between the outer ring and the stirring rod to limit the rotation direction of the stirring rod to be opposite to the rotation direction of the convex ring. A water box is provided on one side of the water-fertilizer integrated box, and the top of the water box is open. A slide bar is connected to the top of the water box, and the slide bar extends to the outside of the water-fertilizer integrated box to connect to the lifting brake mechanism. A water pipe is connected to one side of the water box, and the water pipe is connected to the trace irrigation mechanism. The device is easy to use and avoids blockage;

[0004] During the use of this irrigation equipment, the water source needs to be kept clean. The device does not have an integrated water source filtration function, which directly leads to a large amount of impurities mixed in the irrigation water. Trace irrigation technology, as a highly refined irrigation method, relies on the capillary force of the soil to accurately supply water to the plant roots in a slow and appropriate manner according to the actual needs of the plants. The core of this technology lies in its accuracy and efficiency, but once the irrigation water contains unfiltered impurities, these impurities may gradually accumulate in the irrigation pipes, eventually causing pipe blockage. Pipe blockage will not only reduce irrigation efficiency and affect the normal water absorption of plants, but may also damage the irrigation system, increase maintenance costs, and even shorten the service life of the equipment.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] See also Figure 1 - Figure 6 As shown, a water-fertilizer integrated intelligent trace irrigation device comprises:

[0034] Base 1;

[0035] Four support rods 2 are fixedly connected to one side of the top of the base 1 at equal distances, and a mixing tank 3 is fixedly connected between the four support rods 2. A water source control mechanism 4 is installed on one side of the top of the mixing tank 3.

[0036] The water source control mechanism 4 includes a filter structure 41, an outlet pipe 42, an inlet pipe 43 and a control valve 44. The outer surface of one end of the filter structure 41 is fixedly connected to the inlet pipe 43, the outer surface of the other end of the filter structure 41 is fixedly connected to the control valve 44, the output end of the control valve 44 is fixedly connected to the outlet pipe 42, and the end of the outlet pipe 42 away from the control valve 44 is installed together with the mixing tank 3;

[0037] A fixing frame 7 and a connecting frame 8 are fixedly connected to the other side of the top of the base 1, two fixing rods 9 are fixedly connected between the fixing frame 7 and the connecting frame 8, and a fertilizer box 10 is installed on the top of the two fixing rods 9, a control box 11 is installed at one end of the fixing frame 7, a control panel 12 is installed on the top of the control box 11, and a solenoid valve 15 is installed between the fertilizer box 10 and the mixing tank 3;

[0038] A mixer 6 is installed at the top of the mixing tank 3, and the lower part of the mixer 6 passes through the top of the mixing tank 3 and is installed in the mixing tank 3. An irrigation controller 13 is installed in the middle of the bottom end of the mixing tank 3, and a connecting pipe 14 is installed at one end of the irrigation controller 13. A support frame 5 is installed at the bottom end of the water source control mechanism 4, and the support frame 5 is fixedly connected between the two support rods 2.

[0039] Depend on Figure 2 - Figure 4 It can be seen that the filtering structure 41 includes a filter tank 411, a through groove 413, a filter 414 and a first rubber layer 416. Two first rubber layers 416 are provided, and the two first rubber layers 416 are respectively fixedly connected to the two sides of the inner wall of the filter tank 411. Three limiting grooves 412 are equidistantly provided on the inner wall of the bottom end of the filter tank 411, and the three limiting grooves 412 are all movably connected with insertion blocks 415. The through groove 413 is provided on the top outer surface of the through groove 413, and the filter 414 is movably connected in the through groove 413. The filter tank 411 is fixedly connected to the water inlet pipe 43.

[0040] As can be seen from the above, during the installation process, the filter 414 is firstly accurately inserted into the through groove 413 to ensure that the filter 414 is firmly fixed at the designated position. Subsequently, the through block 415 tightly connected to the filter 414 is inserted into the limiting groove 412, which further enhances the stability of the filter 414 and ensures its accurate positioning during the working process, thereby preventing unnecessary shaking.

[0041] When the system is put into use, clean water is introduced into the filter 414 through the water inlet pipe 43, and impurities and pollutants are effectively removed by the filter 414, and converted into a clear, transparent, and clean water source suitable for use. After the filtration process is completed, the pure water is guided to the outlet pipe 42 under the precise control of the control valve 44, and is transported to the mixing tank 3 through the outlet pipe 42. In the mixing tank 3, the water and the fertilizer are fully mixed and reacted.

[0042] Preferably, the interpenetrating blocks 415 are all fixedly connected to the bottom end of the filter 414 .

[0043] As can be seen from the above, the insertion block 415 is connected to the filter 414 , and during installation, the insertion block 415 is inserted into the limiting groove 412 , so that the filter 414 can be limited.

[0044] Embodiment 2:

[0045] refer to Figure 5 As shown, the filter 414 includes a filter cartridge 441, a slot 442, a filter layer 443, a limit seat 444 and a lifting structure 445. The slot 442 is opened at the top of the filter cartridge 441, and the lifting structure 445 is movably inserted and connected in the slot 442. The outer surfaces of both ends of the filter cartridge 441 are provided with filter layers 443. The limit seat 444 is fixedly connected to one end of one of the filter layers 443, and the filter cartridge 441 is movably inserted and connected in the filter tank 411.

[0046] As can be seen from the above, in the filtering process, water is first introduced into the space of the filter cartridge 441 through the water inlet pipe 43. Once entering, the water flows through the filter layer 443 on one side for preliminary and effective impurity removal, and the water quality is initially purified. Subsequently, the water flow that has undergone preliminary filtration is further deeply processed under the ingenious guidance of the lifting structure 445, effectively removing fine particles in the water and further improving the water quality.

[0047] After this double filtration, the water continues to flow to the other end of the filter cartridge 441, passes through the third layer of protection, and is further filtered by the filter layer 443 at the other end of the filter cartridge 441;

[0048] Finally, the clean water that has passed these three layers of strict filtration is guided into the filter tank 411 to be prepared for subsequent use. Such a multi-layer filtration design not only significantly improves the purity and quality of the water, but also effectively prevents the risk of water pipe blockage, thereby extending the service life of the entire filtration device and ensuring the stable and efficient operation of the irrigation system.

[0049] Preferably, one end of the water inlet pipe 43 passes through the outer surface of the filter cartridge 441 and is movably connected with the limiting seat 444 .

[0050] As can be seen from the above, the water inlet pipe 43 can be limited by the limiting seat 444.

[0051] Embodiment three:

[0052] refer to Figure 6 As shown, the lifting structure 445 includes an upper cover 51, a lifting frame 52, a connecting rod 53, a filter plate 54, a mounting seat 55 and a second rubber layer 56. The lifting frame 52 is fixedly connected to the outer surface of the top end of the upper cover 51, the connecting rod 53 is fixedly connected to the middle of the bottom end of the upper cover 51, the filter plate 54 is fixedly connected to the bottom end of the connecting rod 53, and there are two mounting seats 55 and two second rubber layers 56. The two mounting seats 55 are respectively fixedly connected to the two ends of the connecting rod 53, and the second rubber layer 56 is respectively fixedly connected to the two ends of the upper cover 51. The filter plate 54 is movably inserted and connected in the filter cartridge 441.

[0053] As can be seen from the above, first, the filter plate 54 is accurately passed through the through-slot 442 to ensure that it is firmly placed in the through-slot 442, and then the bottom end of the filter plate 54 is embedded in the bottom inner wall of the filter cartridge 441 to achieve a tight fit and fixation. Next, the connecting rod 53 is smoothly inserted into the through-slot 442 to ensure the stability of the entire structure. Finally, the mounting seat 55 is installed with the filter cartridge 441, and the assembly process of the entire component is completed through appropriate fastening measures, which not only simplifies the assembly steps, but also greatly facilitates the subsequent cleaning and maintenance of the lifting structure 445, effectively preventing the filter layer 443 and the filter plate 54 from being blocked and affecting the normal operation of the equipment, thereby ensuring the continuity and efficiency of use.

[0054] Preferably, the upper cover 51 is configured as an arc structure, the mounting seats 55 are configured as L-shaped structures, and the mounting seats 55 are installed at the top of the filter cartridge 441; the upper cover 51 is movably inserted and connected in the through groove 413, and the two second rubber layers 56 are respectively tightly attached to the two first rubber layers 416.

[0055] As can be seen from the above, the upper cover 51 is set to an arc structure so that it can better fit the filter tank 411, and the mounting seat 55 is connected to the filter tube 441, so as to facilitate the disassembly and assembly of the filter plate 54 and the cleaning of the filter plate 54, and the second rubber layer 56 and the first rubber layer 416 are tightly attached to improve the sealing and avoid water seepage.

[0056] Furthermore, the present invention is designed and applied in agricultural irrigation. By setting soil temperature and humidity sensors, pH sensors, agricultural meteorological stations, etc. in farmland, environmental parameters such as soil moisture, nutrient content, and meteorological conditions are collected in real time. The sensors are used to monitor soil moisture and transmit data to the control box 11. The control box 11 controls the irrigation water volume and time according to the sensor data and the preset irrigation strategy. The irrigation pipeline transports the water source to the irrigation area. Precise irrigation is carried out according to the instructions of the control center. The control box 11 and the control panel 12 are used for setting and control.

[0057] In the intelligent operation process of agricultural irrigation, first, the fertilizer in the fertilizer box 10 is automatically introduced into the mixing tank 3 under the precise control of the solenoid valve 15, waiting to be merged with the water source. At the same time, the other end of the water inlet pipe 43 is tightly connected to the water source pipeline to ensure that the clear water flow can be continuously supplied. This water flow first enters the filter cartridge 441 and passes through the fine screen of the filter layer 443 to effectively remove the suspended matter and impurities in the water. Then, the water flow continues to pass through the filter plate 54, further improving the purity of the water quality. The filtered clean water slowly flows into the guide tube under the precise control of the control valve 44. The water and fertilizer are mixed together in the mixing tank 3 by the mixer 6 to create an irrigation liquid with balanced nutrition and easy for crops to absorb. Finally, the irrigation liquid containing water and fertilizer is transported to the end of the drip irrigation equipment through the connecting pipe 14 under the intelligent scheduling of the irrigation controller 13. The drip irrigation equipment, with its high efficiency, water saving and precise irrigation characteristics, can accurately drop every drop of precious irrigation liquid on the roots of crops, which not only meets the water demand of crop growth, but also minimizes the waste of water, and significantly improves the irrigation efficiency and the yield quality of crops.
