Description

Technical Field

[0001] This invention relates to the field of irrigation equipment, and more particularly to a smart agricultural water-saving irrigation and fertilization device. Background Technology

[0002] Agricultural irrigation and fertilization is a core technology in modern agriculture that deeply integrates fertilization and irrigation. It is also often referred to as fertigation. Its core principle is to fully dissolve soluble fertilizers in irrigation water and then use various irrigation systems such as drip irrigation and sprinkler irrigation to precisely deliver the prepared fertilizer solution to the soil in the root zone of crops. This achieves simultaneous supply and on-demand regulation of water and nutrients, breaking the traditional model of separating irrigation and fertilization. This technology can reduce fertilizer volatilization and water waste, and is suitable for various planting scenarios such as open fields, orchards, and greenhouse vegetables. It helps crops absorb nutrients efficiently and is an important means to promote the precision and intensive development of agriculture, meeting the green and efficient planting needs of modern agriculture.

[0003] In the existing agricultural irrigation and fertilization process, there is still room for improvement in the water and fertilizer mixing process. The most prominent issue is that the mixing process often requires additional power to drive the relevant mixing mechanism to dissolve the fertilizer. This not only increases additional energy costs and agricultural production operating expenses, but also makes the overall operation process relatively cumbersome. It requires staff to specifically manage the start-up, shutdown, and operation status of the power equipment, increasing manpower input. In addition, the addition of extra power equipment also increases the difficulty of equipment maintenance to some extent.

[0004] Therefore, it is necessary to provide a smart agricultural water-saving irrigation and fertilization device to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides a smart agricultural water-saving irrigation and fertilization device, which solves the problem that there is still room for optimization in the water and fertilizer mixing process in existing agricultural irrigation and fertilization processes. The most prominent issue is that the mixing process often requires additional power to drive the relevant mixing mechanism to dissolve the fertilizer. This not only increases additional energy consumption costs and agricultural production operating expenses, but also makes the overall operation process relatively cumbersome. It requires staff to specifically manage the start-up, shutdown, and operation status of the power equipment, increasing manpower input.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , 6 picture, Figure 7 and Figure 8 ,in, Figure 1 A schematic diagram of a preferred embodiment of the smart agricultural water-saving irrigation and fertilization device provided by the present invention; Figure 2 A cross-sectional view of the overall structure provided for this invention; Figure 3 This is a schematic diagram of the flow channel system structure provided by the present invention; Figure 4 This is a schematic diagram of the stirring component structure provided by the present invention; Figure 5 This is a schematic diagram of the baffle structure provided by the present invention; Figure 6 Provided by the present invention Figure 5 A schematic diagram of the structure at point A; Figure 7 This is a schematic diagram of the sealing plate structure provided by the present invention; Figure 8 Provided by the present invention Figure 7 The structural diagram at point B. The smart agriculture water-saving irrigation and fertilization device includes: a dilution tank 1 for diluting water-soluble fertilizer to facilitate irrigation; a flow channel system 2 on the dilution tank 1; a rotating agitator 3 inside the dilution tank 1 that rotates when liquid is added; and a feeding device 4 on the dilution tank 1 that releases water-soluble fertilizer when the agitator 3 rotates.

[0020] The flow channel system 2 includes a water inlet pipe 21 penetrating through the top end of the dilution barrel 1. There are four groups of water inlet pipes 21, which are evenly distributed at the top end of the dilution barrel 1. The water entering the dilution barrel 1 through the water inlet pipe 21 impacts the spiral rotating plate 32, causing the rotating plate 32 to rotate around the axis of the rotating rod 31, and driving the rotating rod 31 and the stirring rod group 33 to rotate. The top end of the water inlet pipe 21 is connected to an O-shaped circulation pipe 22 in a through manner. The two sides of the circulation pipe 22 are respectively connected to a liquid inlet pipe 23 and a first liquid outlet pipe 24 in a through manner. The liquid inlet pipe 23, the circulation pipe 22, and the first liquid outlet pipe 24 are distributed in a middle shape. The center of the bottom end of the dilution barrel 1 is connected to a second liquid outlet pipe 26 in a through manner. One end of the first liquid outlet pipe 24 is connected to an electromagnetic three-way valve 25 in a through manner. One end of the second liquid outlet pipe 26 is connected to one end of the electromagnetic three-way valve 25 in a through manner. The output end of the electromagnetic three-way valve 25 is connected to a liquid extraction pipe 27 in a through manner. One end of the liquid extraction pipe 27 is connected to a pump, and one end of the pump is connected to a drip irrigation pipe.

[0021] Adopting the above scheme: Through the coordinated cooperation of the water inlet pipe 21, the circulation pipe 22, the liquid inlet pipe 23, the first liquid outlet pipe 24, the electromagnetic three-way valve 25, the second liquid outlet pipe 26, and the liquid extraction pipe 27 of the flow channel system 2, the flexible switching between clean water irrigation and water and fertilizer irrigation can be realized. The four groups of water inlet pipes 21 are evenly distributed, enabling the water flow to impact the rotating plate 32 evenly, ensuring the stable rotation of the stirring part 3. At the same time, the setting of the electromagnetic three-way valve 25 can accurately control the water flow path, and cooperate with the pump to achieve the stable transportation of the liquid, which not only meets the principle of first water then fertilizer and then irrigating clean water after fertilization, but also can reduce the residual fertilizer liquid in the pipeline and avoid blockage.

[0022] The stirring part 3 includes a rotating rod 31 penetrating through the top end of the dilution barrel 1 and rotatably connected to the dilution barrel 1. The part of the outer circular surface of the rotating rod 31 that penetrates through the top end of the dilution barrel 1 and extends into the interior of the dilution barrel 1 is fixedly connected with a rotating plate 32 and a stirring rod group 33 respectively. Among them, the rotating plate 32 is located above the stirring rod group 33, the rotating rod 31 is located at the center of the dilution barrel 1, the rotating rod 31 is T-shaped, the rotating plate 32 is spiral, and there are multiple groups of rotating plates, which are evenly distributed on the outer circular surface of the rotating rod 31. The stirring rod group 33 is composed of multiple straight rods, and the multiple straight rods are distributed in a spiral shape. There are three groups of stirring rod groups 33, which are evenly distributed on the outer circular surface of the rotating rod 31.

[0023] Adopting the above scheme: Through the structural design of the rotating rod 31, the rotating plate 32, and the stirring rod group 33 of the stirring part 3, the T-shaped rotating rod can ensure the rotation stability. Multiple groups of spiral rotating plates 32 can efficiently receive the water flow flowing out of the water inlet pipe 21, and use the water flow impact force to achieve self-rotation without additional power. The three groups of spiral-distributed stirring rod groups 33 can stir the liquid in the dilution barrel 1 in all directions, accelerate the dissolution speed of the water-soluble fertilizer, and make the fertilizer liquid concentration uniform.

[0024] The feeding component 4 includes a fertilizer box 41 fixedly connected to the outer circular surface of the dilution tank 1. The fertilizer box 41 is connected to the dilution tank 1 through a hole. A replenishment hole 42 is opened at the top of the fertilizer box 41, and a sealing plug is threaded into the replenishment hole 42. An O-shaped guide block 43 with a right-angled trapezoidal cross-section is fixedly connected to the bottom of the inside of the fertilizer box 41. The inclined surface of the right-angled trapezoidal guide block 43 faces upward, guiding the water and fertilizer to the communication port between the fertilizer box 41 and the dilution tank 1. An annular baffle 44 is fixedly connected to the connection port of the dilution tank 1. A drainage groove 45 is opened through the side end of the baffle 44. Multiple sets of magnetic blocks 46 are embedded in the inner side of the baffle 44. The multiple sets of magnetic blocks 46 are arranged in pairs and symmetrically on both sides of each drainage groove 45. The magnetic poles of the two sets of magnetic blocks 46 on both sides of the drainage groove 45 face different directions towards the inside of the dilution tank 1. An L-shaped rotating groove 47 is opened at the upper and lower ends of the connection port between the fertilizer box 41 and the dilution tank 1. Each set of rotating grooves 47 is rotatably connected to a set of L-shaped rotating rings 48. Multiple sets of arc-shaped sealing plates 49 are fixedly connected between the two sets of rotating rings 48, and there are gaps between the multiple sets of sealing plates 49. The gaps are consistent with the size of the drainage groove 45. Two sets of magnetic blocks 410 are embedded on the outer side of each set of sealing plates 49. The magnetic blocks 410 on each set of sealing plates 49 and the magnetic blocks 46 on both sides of the drainage groove 45 have opposite poles. When the drainage groove 45 is aligned with the area between the two sets of magnetic blocks 410 on the outer side of the sealing plates 49, the two sets of magnetic blocks 46 on both sides of the drainage groove 45 are magnetically attracted to the two sets of magnetic blocks 410 on the outer side of the sealing plates 49. A push plate 411 is fixedly connected to the inner side of one of the multiple sets of arc-shaped sealing plates 49. The push plate 411 is located between the two sets of rotating plates 32. When the rotating plates 32 rotate, they push the push plate 411, causing the sealing plates 49 and rotating rings 48 to rotate.

[0025] The above scheme, through the cooperation of the fertilizer box 41, replenishment hole 42, guide block 43, baffle 44, drainage trough 45, magnetic block 1 46, rotating trough 47, rotating ring 48, sealing plate 49, magnetic block 2 410 and push plate 411 of the feeding component 4, can realize the release of water-soluble fertilizer in small amounts and multiple times. The guide block 43 can guide the fertilizer to flow accurately to the connecting port, reducing residue. The magnetic adsorption of magnetic block 1 46 and magnetic block 2 410 can realize the automatic reset of the sealing plate 49, controlling the feeding timing. The push plate 411 and rotating plate 32 are linked to realize the synchronization of stirring and feeding, avoiding the imbalance of fertilizer concentration caused by excessive feeding at one time, and improving the fertilizer utilization rate.

[0026] The working principle of the smart agricultural water-saving irrigation and fertilization device provided by this invention is as follows: First, connect the inlet pipe 23 to the external water source. In the initial state, adjust the solenoid three-way valve 25 to connect the outlet pipe 24 to the suction pipe 27. Then, start the pump connected to one end of the suction pipe 27. The pump generates pumping force, causing water from the water source to flow sequentially through the inlet pipe 23 into the O-shaped loop pipe 22. The loop pipe 22 distributes the water to four evenly distributed water inlet pipes 21. Most of the water flows through the loop pipe 22 into the outlet pipe 24, then through the solenoid three-way valve 25 and the suction pipe 27 into the pump. Finally, the pump delivers the water to the drip irrigation pipes, achieving clean water irrigation before fertilization and preventing the drip irrigation pipes from being blocked by fertilizer. During this process, some water flows into the dilution tank 1 through the water inlet pipe 21, and the water flow impacts the dilution tank 1 from top to bottom. The spiral rotating plate 32 is fixed to the T-shaped rotating rod 31 located at the center of the dilution tank 1. The impact force of the water flow causes the rotating plate 32 to rotate around the axis of the rotating rod 31, which in turn causes the rotating rod 31 to rotate synchronously. The three sets of spirally distributed stirring rods 33 below the rotating rod 31 also rotate accordingly, preparing for subsequent water-fertilizer mixing. At this time, the rotational force of the rotating plate 32 is greater than the magnetic attraction force between the magnetic block 46 on the baffle 44 and the magnetic block 410 on the sealing plate 49. During the rotation of the rotating plate 32, it will continuously push the push plate 411 located between the two sets of rotating plates 32. The push plate 411 drives the arc-shaped sealing plate 49 fixedly connected to it to rotate. The sealing plate 49 rotates synchronously in the rotating groove 47 through two sets of L-shaped rotating rings 48. The action aligns the gap between the sealing plates 49 with the drainage trough 45 on the baffle 44. Guided by the O-shaped guide block 43 (with a right-angled trapezoidal cross-section and upward-facing slope), the water-soluble fertilizer in the fertilizer box 41 flows precisely to the connection between the fertilizer box 41 and the dilution tank 1. It then flows into the dilution tank 1 in small amounts multiple times through the gap between the drainage trough 45 and the sealing plates 49. Under the continuous stirring of the three sets of spirally distributed stirring rods 33, the flowing water-soluble fertilizer and the water in the dilution tank 1 are quickly and evenly mixed to form a fertilizer solution of suitable concentration. Strictly adhering to the principle of water first, then fertilizer, and dissolving in stages, this avoids excessively high fertilizer concentration causing root burn or excessively low concentration affecting fertilizer efficiency. Afterwards, the electromagnetic three-way valve 25 is adjusted to switch the valve to the state where the outlet pipe 26 is connected to the suction pipe 27. The pump's suction force acts on the outlet pipe 26 at the center of the bottom of the dilution tank 1, drawing out the diluted water-soluble fertilizer from the tank. The fertilizer then passes sequentially through the outlet pipe 26, the solenoid three-way valve 25, the extraction pipe 27, and the pump, ultimately being delivered to the drip irrigation pipe. This achieves integrated water and fertilizer irrigation, precisely delivering the fertilizer solution to the crop root zone. During this process, the pump no longer exerts suction force on the outlet pipe 24, and water from the water source no longer enters the inlet pipe 23, the circulation pipe 22, and the outlet pipe 24. The water supply pipe 21 also no longer replenishes water to the dilution tank 1. Without water impacting the rotating plate 32, the rotational force of the rotating plate 32 gradually decreases, and the rotational force of the sealing plate 49 also weakens. When the magnetic attraction force between the magnetic block 46 and the magnetic block 410 exceeds the rotational force of the sealing plate 49...Two sets of magnetic blocks 46, located on either side of the drainage trough 45, are magnetically connected to two sets of magnetic blocks 410 on the outer side of the sealing plate 49, causing the sealing plate 49 to reset and seal the drainage trough 45. Then, the electromagnetic three-way valve 25 is adjusted again to reconnect the outlet pipe 24 with the suction pipe 27, allowing the pump to draw clean water again. This water flows through the inlet pipe 23, circulation pipe 22, outlet pipe 24, electromagnetic three-way valve 25, suction pipe 27, and drip irrigation pipe, with some water entering the dilution tank 1 to rinse the dilution tank 1 and fertilizer box 41. The flow path is then switched again to extract the cleaning solution from the dilution tank 1 for irrigating the crops. This flow path switching operation is repeated several times to rinse away any residual fertilizer solution within the entire device, preventing pipe blockage and ensuring even fertilizer penetration into the crop root zone, adhering to the principle of fertilizing before irrigating. The stirring element 3 requires no additional power; it achieves autonomous operation using water flow impact. Rotation saves energy and is easy to operate. The spiral rotating plate 32 can efficiently withstand the impact of water flow and ensure rotational stability. The three sets of spirally distributed stirring rods 33 can stir the liquid in the dilution tank 1 in all directions, accelerate the dissolution speed of water-soluble fertilizer, make the fertilizer solution uniform, and avoid local concentrations that are too high or too low, which will affect crop growth. At the same time, the rotating plate 32 is linked with the push plate 411 to realize the synchronization of stirring and feeding, improve the automation level of the device, and reduce manual intervention. The timing and amount of water-soluble fertilizer release can be controlled by the feeding component 4, realizing small-scale multiple feeding, which conforms to the principle of staged dissolution. The guide block 43 can guide the fertilizer to flow precisely to the connection port, reducing fertilizer residue. The magnetic block adsorption realizes the automatic reset of the sealing plate 49, eliminating the need for manual control of feeding start and stop. The linkage stirring component 3 realizes the synchronous supply of water and fertilizer, improves fertilizer utilization, avoids waste, and prevents fertilizer solution concentration imbalance, ensuring irrigation and fertilization effects.

[0027] Compared with related technologies, the smart agricultural water-saving irrigation and fertilization device provided by this invention has the following beneficial effects: The stirring component 3 can rotate autonomously without additional power by using the impact of water flow, saving energy and making operation convenient. The spiral rotating plate 323 can efficiently withstand the impact of water flow and ensure rotational stability. The three sets of spirally distributed stirring rods 33 can stir the liquid in the dilution tank 1 in all directions, accelerate the dissolution speed of water-soluble fertilizer, make the fertilizer solution uniform, and avoid local concentrations that are too high or too low, which will affect crop growth. At the same time, the rotating plate 32 is linked with the push plate 411 to realize the synchronization of stirring and feeding, improve the automation level of the device, and reduce manual intervention. The timing and amount of water-soluble fertilizer release can be controlled by the feeding component 4, enabling multiple small-volume feedings that conform to the principle of dissolving in stages. The guide block 43 guides the fertilizer to flow precisely to the connection port, reducing fertilizer residue. The magnetic block adsorption enables the sealing plate 49 to automatically reset, eliminating the need for manual control of the feeding start and stop. The linkage stirring component 3 enables simultaneous water and fertilizer supply, improving fertilizer utilization, avoiding waste, and preventing fertilizer concentration imbalance, thus ensuring irrigation and fertilization effects.

There are gaps between the multiple sets of sealing plates (49), and the gaps are consistent with the size of the drainage tank (45). Two sets of magnetic blocks (410) are embedded on the outside of each set of sealing plates (49). The set of magnetic blocks (410) on each set of sealing plates (49) and the set of magnetic blocks (410) on both sides of the drainage tank (45) are connected to each other. 46) When the corresponding surfaces are opposite poles, and the area between the two sets of magnetic blocks (410) on the outside of the drain trough (45) and the sealing plate (49) is aligned, the two sets of magnetic blocks (46) on both sides of the drain trough (45) are magnetically attracted to the two sets of magnetic blocks (410) on the outside of the sealing plate (49). A push plate (411) is fixedly connected to the inner side of one of the multiple sets of arc-shaped sealing plates (49). The push plate (411) is located between the two sets of rotating plates (32). When the rotating plate (32) rotates, it pushes the push plate (411), causing the sealing plate (49) and the rotating ring (48) to rotate.
