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] For example, see Figure 1-Figure 4 The present invention provides a technical solution: a farmland water and fertilizer integrated irrigation equipment, including a delivery box 1, a mixing barrel 3 is fixedly connected to the top of the delivery box 1, a feeding chamber 4 is fixedly connected to the left side of the mixing barrel 3, a suction pump 2 is fixedly connected to the top of the delivery box 1, and a delivery block 5 is fixedly connected to the surface of the suction pump 2. First, water from the water source is sucked into the delivery block 5 through the suction pump 2, and the water flows into the interior of the mixing barrel 3 through the delivery block 5. Then, fertilizer is introduced into the interior of the mixing barrel 3 through the feeding chamber 4. When the fertilizer and water are mixed, the bottom of the mixing barrel 3 is started. The power device drives the stirring rod 10 to rotate, so that the fertilizer and water are stirred and mixed into a water-fertilizer solution. Finally, the water-fertilizer solution in the mixing barrel 3 is sucked through the nozzle 6 and the farmland is sprinkled. The end of the conveying block 5 away from the suction pump 2 is fixedly connected to the inner wall of the mixing barrel 3, the right side of the mixing barrel 3 is fixedly connected with the nozzle 6, and the nozzle 6 is fixedly connected to the top of the conveying box 1. The stirring rod 10 is rotatably connected to the bottom of the inner wall of the mixing barrel 3. The inner wall of the mixing barrel 3 is provided with a telescopic mechanism 9, and the inner wall of the conveying block 5 is provided with a filtering mechanism 7. It also includes:

[0033] The filtering mechanism 7 includes an elastic ring 701, one end of which is fixedly connected to the bottom of the inner wall of the conveying block 5. The elastic ring 701 has a telescopic elastic function. When the filter block 704 slides outward to a certain distance, the filter block 704 will be driven to slide inward and reset through the elastic ring 701. The end of the elastic ring 701 away from the bottom of the inner wall of the conveying block 5 is fixedly connected to a connecting rod 703, and push membranes 702 are fixedly connected to both sides of the connecting rod 703. The end of the connecting rod 703 away from the elastic ring 701 is fixedly connected to the filter block 704. The filter block 704 is slidably connected to both sides of the inner wall of the conveying block 5 through a slider. A telescopic capsule 705 is slidably connected to the surface slot of the filter block 704. The telescopic capsule 705 is made of a characteristic material that can be stretched inside and outside, and a pressure hole is opened inside. Compressed gas is injected inside. When the telescopic capsule 705 is squeezed, the internal gas is squeezed into the compression tube 7062. Cleaning components 706 are provided on both sides of the inner wall of the filter block 704.

[0034] The cleaning assembly 706 includes a side plate 7061, which is fixedly connected to both sides of the inner wall of the filter block 704. A compression tube 7062 is fixedly connected to the bottom of the inner wall of the side plate 7061. The end of the compression tube 7062 away from the bottom of the inner wall of the side plate 7061 is fixedly connected to a contact block 7063. The surface of the contact block 7063 is fixedly connected to an extrusion membrane 7064. The right side of the contact block 7063 is fixedly connected to a jet chamber 7065. Four jet membranes are installed at the surface of the jet chamber 7065. When the jet chamber 7065 ejects gas outward, it will push the jet membrane, and the jet membrane has the characteristic of telescopic reset. When the ejected gas disappears, the jet membrane will reset to its original position and cover the ejection hole.

[0035] The working method of the first embodiment is as follows: a leather hose is tied to the water inlet pipe of the suction pump 2, and one end of the leather hose is connected to the water source. When the suction pump 2 is started, the water in the water source is sucked into the conveying block 5 through the leather hose. When the water flows inside the conveying block 5, it will impact the push membrane 702. The impact force generated on the push membrane 702 will push the filter block 704, so that the filter block 704 slides toward the mixing barrel 3. When the water flows from the inside of the conveying block 5 to the inside of the mixing barrel 3, it will pass through the inside of the filter block 704. After the filter block 704 filters the impurities in the water flow into the inside, the water flow will continue to flow into the mixing barrel 3. When the filter block 704 slides toward the surface of the spray plate 801 inside the conveying block 5, the plug-in tube 803 will squeeze the telescopic capsule 705, so that the telescopic capsule 705 shrinks inward into the filter block 704. The telescopic capsule 705 05 After being squeezed, gas will be generated and flow into the side plate 7061 through the internal passage of the filter block 704. The gas will drive the compression tube 7062 to expand and contract outward. When the compression tubes 7062 on both sides expand and contract outward and drive the contact block 7063 to move and contact together, the extrusion membranes 7064 on both sides will collide with each other, thereby ejecting the gas in the compression tube 7062 to the outside through the jet chamber 7065. The ejected gas will blow the water-fertilizer solution at the filter holes on the surface of the filter block 704, thereby preventing a large amount of impurities in the water-fertilizer solution from clogging the filter holes. Impurities in the water flow can be filtered to prevent a large amount of impurities in the water from mixing with fertilizers. If they are not cleaned up in time, they will eventually adhere to the inside of the mixing barrel 3 and become more difficult to remove. At the same time, impurities in the water flow can be prevented from clogging the filter holes inside the filter block 704.

[0036] Embodiment 2: Based on Embodiment 1, continue to refer to Figure 5-Figure 6 The pushing mechanism 8 includes a spray plate 801 fixedly connected to the bottom of the inner wall of the mixing barrel 3, the bottom of the stirring rod 10 contacts the inner wall of the spray plate 801, and the inner walls of the spray plate 801 are slidably connected with push films 802 on both sides through sliders. The surface of the spray plate 801 is fixedly connected with a plug-in tube 803, and a bottom cleaning component 804 is provided at the surface slot of the spray plate 801;

[0037] The bottom cleaning component 804 includes a pressure membrane 8041 fixedly connected to the surface slot of the spray plate 801, a compression rod 8042 fixedly connected to the surface of the pressure membrane 8041, the compression rod 8042 is made of a soft rubber material that can be extended and retracted inward and outward, and a cavity is opened inside. When the compression rod 8042 receives gas, it will retract and retract outward. A folding plate 8043 is fixedly connected to the surface of the compression rod 8042, and an absorption block 8044 is fixedly connected to the surface of the folding plate 8043. A filter net that can filter impurities is installed inside the absorption block 8044, and impurities in the water-fertilizer solution can be filtered into the interior through the absorption block 8044.

[0038] The working method of the second embodiment is as follows: when the filter block 704 slides outward to the surface of the spray plate 801, it will squeeze the push film 802, so that the push film 802 will be retracted inwardly into the inside of the spray plate 801. When one end of the push film 802 is squeezed by the outside, the gas inside the push film 802 will be squeezed outward into the pressure film 8041. The pressure film 8041 receives the gas and drives the compression rod 8042 to retract outward. The outward retracted compression rod 8042 drives the folding plate 8043 to retract outward. Through the folding plate 8043 and the mixing barrel 3, the folding plate 8043 and the mixing barrel 3 are connected. The bottom of the inner wall is in sliding contact, thereby pushing the water-fertilizer solution at the bottom of the inner wall of the mixing barrel 3, so that the water-fertilizer solution staying at the bottom of the inner wall of the mixing barrel 3 surges upward, and at the same time, the impurities in the water-fertilizer solution are absorbed into the interior through the absorption block 8044. When water and fertilizer are mixed, the impurities generated will sink and adhere to the bottom of the inner wall of the mixing barrel 3. By setting up this mechanism, the water-fertilizer solution at the bottom of the inner wall of the mixing barrel 3 can be turned over, thereby preventing a large amount of impurities after the water-fertilizer solution is mixed from sinking into the bottom of the inner wall of the mixing barrel 3, and at the same time, the impurities attached to the bottom of the inner wall of the mixing barrel 3 are absorbed.

[0039] Example 3: Based on Example 2, continue to refer to Figure 7-Figure 9 The telescopic mechanism 9 includes a telescopic plate 901, which is fixedly connected to the inner wall of the mixing barrel 3, a stretching tube 902 is slidably connected to the surface slot of the telescopic plate 901, a telescopic belt 903 is fixedly connected to the bottom of the inner wall of the telescopic plate 901, and a mobile clamp 904 is fixedly connected to one end of the telescopic belt 903 away from the bottom of the inner wall of the telescopic plate 901, and the mobile clamp 904 is slidably connected to the inner wall of the telescopic plate 901, and a telescopic tube 906 is fixedly connected to the top of the mobile clamp 904, and one end of the telescopic tube 906 away from the mobile clamp 904 is fixedly connected to the top of the inner wall of the telescopic plate 901, a material storage component 907 is provided on the top of the telescopic plate 901, and a covering component 905 is provided on the inner wall of the mobile clamp 904.

[0040] The covering assembly 905 includes a covering arm 9051, which is fixedly connected to the inner wall of the movable clamp 904, a suction and pressure bag 9052 is fixedly connected to the right side of the covering arm 9051, a contact pad 9053 is fixedly connected to the left slot of the covering arm 9051, a pressing ring 9054 is slidably connected to the inner wall of the contact pad 9053, and a discharge hole is opened inside the covering arm 9051, one end of the discharge hole is opened inside the contact pad 9053, and the other end extends into the interior of the movable clamp 904, and enters the interior of the telescopic tube 906 from the interior of the movable clamp 904.

[0041] The material storage component 907 includes a mounting plate 9071, which is fixedly connected to the top of the telescopic plate 901. A material storage groove is provided inside the mounting plate 9071. When subjected to external pressure, impurities in the water-fertilizer solution will be sprayed outward. A connecting frame 9072 is fixedly connected to the top of the mounting plate 9071. Reset rods 9073 are fixedly connected to both sides of the inner wall of the connecting frame 9072. An air pressure groove is provided on the surface of the reset rod 9073. When the internal gas of the telescopic tube 906 flows into the reset rod 9073, it will be sprayed out from the air pressure groove and push the compression ball 9074. The surface of the reset rod 9073 is slidably connected to the compression ball 9074, and the surface of the connecting frame 9072 is fixedly connected to the injection pipe 9075.

[0042] The working method of the third embodiment is as follows: when the compression rod 8042 is extended outward to the surface of the telescopic plate 901, one end of the compression rod 8042 will squeeze the stretch tube 902, so that the stretch tube 902 shrinks inward into the interior of the telescopic plate 901. After the stretch tube 902 is squeezed, gas will flow into the interior of the telescopic belt 903, thereby driving the telescopic belt 903 to extend toward the top and push the mobile clamp 904, so that the mobile clamp 904 slides toward the top on the inner wall of the telescopic plate 901. When the mobile clamp 904 slides, the covering arm 9051 inside it will contact the inner wall of the mixing barrel 3, and when the contact pad 9053 contacts the inner wall of the mixing barrel 3, it will press The ring 9054 makes contact, so that the pressing ring 9054 expands and contracts inwardly inside the contact pad 9053, and at the same time, it will generate pressure on the inside of the suction and pressure bag 9052 on the right side of the covering arm 9051, so that negative pressure suction is generated inside the suction and pressure bag 9052, and the generated negative pressure suction will absorb the impurities attached to the surface of the wall of the mixing barrel 3 through the absorption holes on the surface of the contact pad 9053 and absorb them into the interior of the contact pad 9053. When the water-fertilizer solution is mixed on the inner wall of the mixing barrel 3, the impurities in the mixed water-fertilizer solution will adhere to the surface of the barrel wall, and the impurities attached to the barrel wall of the mixing barrel 3 can be absorbed. If the impurities on the surface of the barrel wall are not cleaned in time, the water and fertilizer will be mixed in the subsequent mixing. When mixing, the impurities on the wall surface of the mixing barrel 3 are mixed together. When the movable clamp 904 slides upward on the inner wall of the telescopic plate 901, the telescopic tube 906 is squeezed through the top of the movable clamp 904, so that the telescopic tube 906 is stretched inward. At the same time, the internal gas is transmitted to the inside of the reset rod 9073 through the inside of the mounting plate 9071, so that the compression ball 9074 slides on the surface of the reset rod 9073. When the compression ball 9074 slides to the top to the top of the inner wall of the connecting frame 9072, the surface of the compression ball 9074 is squeezed, so that the impurities in the contact pad 9053 are sucked out by negative pressure. The internal passage of the arm 9051 is absorbed into the telescopic tube 906. When the telescopic tube 906 is extended and retracted inwardly, the generated gas will flow upward and spray the impurities inside it upward into the interior of the mounting plate 9071. When the pouring work is completed, the top cover of the mixing barrel 3 is opened, and one end of the spray tube 9075 can be pressed to make the spray tube 9075 generate pressure inwardly on the interior of the mounting plate 9071, so that the impurities inside the mounting plate 9071 flow out through the nozzle of the spray tube 9075, and the impurities in the contact pad 9053 can be cleaned, thereby preventing a large amount of impurities from staying inside the contact pad 9053 and clogging the absorption holes on the surface of the contact pad 9053.
