Description

Technical Field

[0001] This invention relates to the field of irrigation equipment technology, and more specifically to a water-saving irrigation device and method that can handle crops of different densities. Background Technology

[0002] Stable agricultural production is essential for our livelihood. To ensure the normal growth of agricultural products, we need to provide a large amount of water. However, some water-scarce areas cannot guarantee the supply of irrigation water and must conserve water so that the limited water supply can be used to grow more crops.

[0003] For example, Chinese invention patent CN114175991A discloses an agricultural water-saving irrigation device, in which a main water tank with a water pump and an auxiliary water tank are connected by a connecting water pipe with a switch valve. A sprinkler filter device is installed on the connecting water pipe with the switch valve. Several pipe joints corresponding to the nozzle plate connecting pipe are installed on the horizontal end of the auxiliary water tank, and the nozzle plate connecting pipe and the corresponding pipe joint are detachably connected by a union.

[0004] However, it still has the following drawbacks: the irrigation device can only irrigate plants of a certain planting density, which limits the types of crops that can be planted. At the same time, when the water spray device is blocked, it cannot be detected and dealt with in time, resulting in some plants not receiving irrigation water.

[0005] Based on this, the present invention designs a water-saving irrigation device and method that can handle crops of different densities to solve the above problems. Summary of the Invention

[0018] Furthermore, the feeding device includes a support column, a feeding funnel, a support frame, a feeding pipe, a rotating wheel, a sealing plate, a gear, a slot, and a feed inlet.

[0019] To better achieve the objectives of this invention, the present invention also provides a method for a water-saving irrigation device capable of handling crops of different densities, comprising the following steps:

[0020] Step 1: Irrigation water is delivered to the U-shaped branch pipe through the branch pipe of the continuous water supply assembly's sprinkler system. The blockage alarm device in pipe three ensures that water flows only into the front end of the U-shaped branch pipe, spraying it onto the crops through the sprinkler head. When a sprinkler head becomes blocked, the increased water pressure inside the U-shaped branch pipe exceeds the magnetic attraction, causing the water to flow through pipe three, pushing the baffle plate two and the rotating column along the support block two, resulting in water being sprayed out from the rear sprinkler head. The conductivity of the water flow creates a closed circuit between the conductive rods at both ends, triggering the buzzer to sound an alarm. When replacing the blockage... When the nozzle is removed, it is taken out downward along the direction of the U-shaped branch pipe. At this time, the baffle plate is no longer squeezed by the nozzle. The spring pulls the connecting plate to rotate, and the connecting plate pulls the baffle plate to rotate on the support block to block the water pipe. Then, the nozzle to be replaced is moved upward along the U-shaped branch pipe while squeezing the baffle plate to rotate along the support block. When the rear nozzle starts to work, the water pressure in the U-shaped branch pipe decreases. At this time, the magnet attracts the baffle plate, so that the front nozzle stops spraying water. Since there is no water flow, the buzzer stops working and stops the alarm.

[0021] Step 2: Fill the water tank with water through the inlet pipe of the irrigation regulating device. At this time, open the electric valve three on the connecting pipe and the water flows into pipe two through the connecting pipe. When the plants are densely planted, open the electric valve four to drive the valve ball to rotate and make the water flow into the U-shaped pipe to supply water to the device. When the plants are sparsely planted, turn the electric valve four to drive the valve ball to rotate and make the water flow into the left or right end of the U-shaped pipe.

[0022] Step 3: Open the electric valve 1 on pipe 1 to allow water to flow into the box through pipe 1. When enough water has been added, close the electric valve 1. At this time, start the motor and drive the rotating roller through the output end of the motor. The rotation of the rotating roller drives the mixing plate to rotate, so that the fertilizer and water are fully mixed. Open the electric valve 2 to transport the liquid of fertilizer and water fully mixed to the plants through the connecting pipe.

[0023] Step 4: By rotating the wheel of the feeding device, the gear is driven to rotate. The rotation of the gear causes the sealing plate to move up and down in the slot on the box. The movement of the sealing plate causes the feed inlet to move, so that the feed inlet is connected to the feeding pipe. Fertilizer is poured into the feeding funnel and flows into the box through the feeding pipe.

[0024] The present invention has the following technical effects:

[0025] 1. This invention delivers irrigation water to a U-shaped branch pipe via a branch pipe of a continuous water supply assembly's sprinkler irrigation device. A three-stage sealing and blockage alarm device ensures water flow is restricted to the front end of the U-shaped branch pipe. Water is then sprayed onto crops through a nozzle. When a nozzle becomes blocked, the increased water pressure within the U-shaped branch pipe exceeds the magnetic attraction, causing water to flow through the three-stage sealing device, pushing the baffle plate and rotating column along the support block to rotate and exit through the rear nozzle. The conductivity of the water flow creates a closed circuit between the conductive rods at both ends, triggering a buzzer alarm. When replacing the blocked device, the nozzle is removed downwards along the U-shaped branch pipe. The baffle plate is no longer compressed by the nozzle, and the spring's contraction pulls the connecting plate to rotate, causing the baffle plate to move. Water plate one rotates on support block one to block the water pipe. At this time, the nozzle to be replaced is moved upward along the U-shaped branch pipe while squeezing water baffle one to rotate along support block one. When the rear nozzle starts working, the water pressure in the U-shaped branch pipe decreases. At this time, the magnet attracts water baffle two, so that the front nozzle stops spraying water. Since there is no water flow, the buzzer stops working and stops alarming. When the device is blocked, the backup device is activated to supply water to the plant to avoid uneven watering that could lead to plant death. At the same time, when the backup device is activated, an alarm is issued in time to remind the staff to replace the device. At the same time, when replacing the device, a large amount of water is sprayed out of the pipe, which interferes with the staff's replacement of the device. Also, a large amount of water is prevented from washing away the soil of the plant roots, which could lead to plant death.

[0026] 2. This invention injects water into the water tank through the inlet pipe of the irrigation regulating device. At this time, the electric valve three on the connecting pipe is opened, and the water flows into the pipe two through the connecting pipe. When the plants are densely planted, the electric valve four is opened, which drives the valve ball to rotate, allowing the water to flow into the U-shaped pipe to supply water to the device. When the plants are sparsely planted, the electric valve four is rotated, which drives the valve ball to rotate, allowing the water to flow into the left or right end of the U-shaped pipe. By adjusting the water flow direction of the device, water is supplied to specific pipes, thereby meeting the watering needs of plants with different planting densities and preventing water waste.

[0027] 3. This invention allows water to flow into the tank by opening the electric valve one on pipe one. When enough water is added, the electric valve one is closed. At this time, the motor is started, and the output end of the motor drives the rotating roller to rotate. The rotation of the rotating roller drives the stirring plate to rotate, so that the fertilizer and water are fully mixed. By opening the electric valve two, the liquid of fertilizer and water is transported to the plant through the connecting pipe. By mixing fertilizer and water, nutrients are provided to the plant at the same time as irrigation, eliminating the need for manual fertilization, improving work efficiency. At the same time, the fertilizer can be accurately delivered to the root system of the plant, improving the utilization rate of fertilizer. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] The present invention will be further described below with reference to embodiments.

[0043] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0044] Example 1

[0045] Please refer to the instruction manual appendix. Figure 1-10 A water-saving irrigation device that can handle crops of different densities, including a U-shaped pipe 1;

[0046] The upper end of the U-shaped pipe 1 is equipped with a continuous water supply component 5 to ensure a continuous water supply to the plant.

[0047] The continuous water supply component 5 includes a water spraying device 51 and a sealing blockage alarm device 52. The U-shaped pipe 1 is connected to the water spraying device 51, and the water spraying device 51 is connected to the sealing blockage alarm device 52.

[0048] The water spraying device 51 includes a U-shaped branch pipe 511, a support block 512, a baffle plate 513, a spring 514, a connecting plate 515, a nozzle 516, and branch pipes 517. Multiple branch pipes 517 are fixedly connected at equal intervals on the left and right sides of the upper end of the U-shaped pipe 511. A U-shaped branch pipe 511 is fixedly connected to the lower end of each branch pipe 517. The U-shaped branch pipe 511 is connected to a sealing and clogging alarm device 52. Nozzles 516 are threadedly connected to the front and rear sides of the lower end of the U-shaped branch pipe 511. The inner walls of the front and rear sides of the lower end of the branch pipe 511 are respectively provided with cylindrical grooves 518. Multiple pairs of support blocks 512 are fixedly connected at equal intervals to the bottom of the cylindrical grooves 518. Each pair of support blocks 512 is rotatably connected to a baffle plate 513 at one end facing each other. A connecting plate 515 is fixedly connected to the lower end of the baffle plate 513 near the nozzle 516. The bottom of the cylindrical groove 518 is fixedly connected to one end of multiple springs 514. The other end of the springs 514 is fixedly connected to the connecting plate 515 one by one.

[0049] The sealing blockage alarm device 52 includes a pipe 3 521, a support block 2 522, a magnet 523, a water baffle 2 524, a buzzer 525, a rotating column 526, and a conductive rod 527. The pipe 3 521 is fixedly connected to the inner wall of the rear end of the U-shaped branch pipe 511. The magnet 523 is fixedly connected to the lower side of the rear end of the pipe 3 521. A pair of support blocks 2 522 are fixedly connected to the upper side of the rear end of the pipe 3 521. The rotating column 526 is rotatably connected to one end of the support blocks 2 522 facing each other. The water baffle 2 524 is fixedly connected to the lower end of the rotating column 526. The water baffle 2 524 is attracted to the rear end of the magnet 523. The conductive rod 527 is fixedly connected to the left and right sides of the rear end of the U-shaped branch pipe 511 respectively. The buzzer 525 is fixedly connected to the upper end of the conductive rod 527.

[0050] Preferably, the second water baffle 524 is made of a metal material that can be attracted by a magnet 523;

[0051] The water baffle 524 is attracted by the magnet 523, which can prevent water from flowing into the front end of 511;

[0052] In this embodiment of the invention, when the device starts irrigating, irrigation water is delivered to the U-shaped branch pipe 511 through the branch pipe 517 of the continuous water supply component 5. The blockage alarm device 52's pipe three 521 blocks the flow, ensuring the water only flows into the front end of the U-shaped branch pipe 511. Water is then sprayed onto the crops through the nozzle 516. When the nozzle 516 becomes blocked, the increased water pressure inside the U-shaped branch pipe 511 exceeds the attraction of the magnet 523. The water flow pushes the baffle plate two 524 and the rotating column 526 along the support block two 522, causing the water to spray out from the rear nozzle 516. The conductivity of the water flow causes the conductive rods 527 at both ends to form a closed circuit, triggering the buzzer 525 to sound an alarm. When replacing the blocked device, the nozzle 516 is removed downwards along the direction of the U-shaped branch pipe 511. At this time, the baffle plate one 513 is no longer compressed by the nozzle 516, and the spring 514... The retracting pull of the connecting plate 515 rotates the water baffle 513, which in turn rotates on the support block 512 to block the water pipe. At this time, the nozzle 516 to be replaced moves upward along the U-shaped branch pipe 511 while simultaneously squeezing the water baffle 513 to rotate along the support block 512. When the rear nozzle 516 starts working, the water pressure in the U-shaped branch pipe 511 decreases. At this time, the magnet 523 attracts the water baffle 524, causing the front nozzle 516 to stop discharging water. Since there is no water flow, the buzzer 525 stops working and stops alarming. When the device is blocked, the backup device is activated to supply water to the plant, avoiding uneven watering that could lead to plant death. At the same time, when the backup device is activated, an alarm is promptly issued to remind the staff to replace the device. This also prevents a large amount of water from spraying out of the pipe, interfering with the staff's replacement of the device, and also prevents a large amount of water from washing away the soil from the plant roots, which could lead to plant death.

[0053] Example 2

[0054] Please refer to the instruction manual appendix. Figure 4-8 The U-shaped pipe 1 is equipped with an irrigation regulating device 4 for regulating the irrigation of the plants, and the irrigation regulating device 4 is connected to the fertilizer mixing and conveying device 2.

[0055] The irrigation regulating device 4 includes a water tank 41, an electric valve 42, a pipe 43, a connecting pipe 44, a valve ball 45, an electric valve 46, and an inlet pipe 47. The electric valve 46 is fixedly connected to the upper rear end of the U-shaped pipe 1. The lower end of the electric valve 46 passes through the U-shaped pipe 1 and is fixedly connected to the valve ball 45. The pipe 43 is fixedly connected to the rear end of the U-shaped pipe 1. The rear ends of multiple pipes 43 are fixed at equal intervals on the connecting pipe 44. The electric valve 42 is fixedly connected to the upper left rear end of the connecting pipe 44. The connecting pipe 44 is connected to the fertilizer mixing and conveying device 2. The water tank 41 is fixedly connected to the left rear end of the connecting pipe 44. The water tank 41 is connected to the fertilizer mixing and conveying device 2. The inlet pipe 47 is fixedly connected to the upper left side of the water tank 41.

[0056] Preferably, the valve ball 45 has a T-shaped water groove;

[0057] The T-shaped water trough facilitates the flow of water from pipe 43 into both ends of U-shaped pipe 1;

[0058] In this embodiment of the invention, when the device starts supplying water, water is injected into the water tank 41 through the water inlet pipe 47 of the irrigation regulating device 4. At this time, the electric valve 42 on the connecting pipe 44 is opened, and the water flows into the pipe 43 through the connecting pipe 44. When the plants are densely planted, the electric valve 46 is opened, which drives the valve ball 45 to rotate, so that the water flows into the U-shaped pipe 1 to supply water to the device. When the plants are sparsely planted, the electric valve 46 is rotated, which drives the valve ball 45 to rotate, so that the water flows into the left or right end of the U-shaped pipe 1. By adjusting the water flow direction of the device, water is supplied to specific pipes, thereby meeting the watering needs of plants with different planting densities and preventing waste of water resources.

[0059] Example 3

[0060] Please refer to the instruction manual appendix. Figure 4-6 The irrigation regulating device 4 is equipped with a fertilizer mixing and conveying device 2 that provides fertilizer to the device, and the fertilizer mixing and conveying device 2 is connected to the feeding device 3.

[0061] The fertilizer mixing and conveying device 2 includes a housing 21, a motor 22, a first pipe 23, an electric valve 24, an electric valve 25, a mixing plate 26, and a rotating roller 27. The second electric valve 25 is fixedly connected to the upper right end of the rear end of the connecting pipe 44. The housing 21 is fixedly connected to the rear end of the connecting pipe 44. The housing 21 is connected to the feeding device 3. The motor 22 is fixedly connected to the upper end of the housing 21. The output end of the motor 22 passes through the upper end of the housing 21 and is fixedly connected to the rotating roller 27. The lower end of the rotating roller 27 is rotatably connected to the bottom of the housing 21. Multiple mixing plates 26 are fixedly connected at equal intervals on both the left and right ends of the rotating roller 27. The first pipe 23 is fixedly connected to the upper left end of the housing 21. The first electric valve 24 is fixedly connected to the upper end of the first pipe 23. The left end of the first pipe 23 is fixedly connected to the water tank 41.

[0062] In this embodiment of the invention, when the device is ready to mix fertilizer, the electric valve 24 on pipe 23 is opened to allow water to flow into the box 21 through pipe 23. When enough water is added, the electric valve 24 is closed. At this time, the motor 22 is started, and the output end of the motor 22 drives the rotating roller 27 to rotate. The rotation of the rotating roller 27 drives the mixing plate 26 to rotate, so that the fertilizer and water are fully mixed. The electric valve 25 is opened to deliver the liquid of fertilizer and water fully mixed to the plants through the connecting pipe 44. By mixing fertilizer and water, nutrients are provided to the plants while irrigating, eliminating the need for manual fertilization, improving work efficiency. At the same time, the fertilizer can be accurately delivered to the root system of the plants, improving the utilization rate of fertilizer.

[0063] The fertilizer mixing and conveying device 2 is equipped with a feeding device 3 for conveying fertilizer into the device;

[0064] The feeding device 3 includes a support column 31, a feeding funnel 32, a support frame 33, a feeding pipe 34, a rotating wheel 35, a sealing plate 36, a gear 37, a slot 38, and a feed inlet 39. The feeding pipe 34 is fixedly connected to the right end of the housing 21, and the feeding funnel 32 is fixedly connected to the right end of the feeding pipe 34. The support column 31 is fixedly connected to the lower end of the feeding funnel 32. The support column 31 is fixedly connected to the feeding pipe 34 through the support frame 33. A gear 37 is provided at the right end of the housing 21. A gear 37 is rotatably connected to the upper rear end of the gear 37. The gear 37 passes through the housing 21 and is fixedly connected to the rotating wheel 35. The front end of the gear 37 meshes with the teeth on the sealing plate 36. A feed inlet 39 is provided at the lower end of the sealing plate 36.

[0065] In this embodiment of the invention, when the device is ready to fertilize, the rotating wheel 35 of the feeding device 3 drives the gear 37 to rotate. The rotation of the gear 37 drives the sealing plate 36 to move up and down in the slot 38 opened on the box 21. The movement of the sealing plate 36 drives the inlet 39 to move, so that the inlet 39 is connected to the feeding pipe 34. Fertilizer is poured into the feeding funnel 32. The fertilizer flows into the box 21 along the feeding pipe 34. The device is supported by the support column 31 and the support frame 33. After the fertilizer is added, the rotating wheel 35 drives the sealing plate 36 to move downward to block the feeding pipe 34. By adding fertilizer into the device, it is ensured that the device can deliver nutrient-rich water to the plant roots.

[0066] Example 4

[0067] Please refer to the instruction manual appendix. Figure 1-10 The present invention provides a method for using the water-saving irrigation device that can handle crops of different densities, comprising the following steps:

[0068] Step 1: Irrigation water is delivered to the U-shaped branch pipe 511 through the branch pipe 517 of the continuous water supply component 5's sprinkler irrigation device 51. The blockage alarm device 52's pipe three 521 prevents water from flowing only into the front end of the U-shaped branch pipe 511, where it is sprayed onto the crops through the nozzle 516. When the nozzle 516 becomes blocked, the increased water pressure inside the U-shaped branch pipe 511 exceeds the attraction of the magnet 523. The water then flows through pipe three 521, pushing the baffle plate two 524 and the rotating column 526 to rotate along the support block two 522, resulting in water being sprayed out from the rear nozzle 516. The conductivity of the water flow causes the conductive rods 527 at both ends to form a closed circuit, triggering the buzzer 525 to sound an alarm. When replacing the blocked device... When the nozzle 516 is taken out downward along the direction of the U-shaped branch pipe 511, the baffle plate 513 is no longer squeezed by the nozzle 516. The spring 514 pulls the connecting plate 515 to rotate. The connecting plate 515 pulls the baffle plate 513 to rotate on the support block 512 to block the water pipe. At this time, the nozzle 516 to be replaced is moved upward along the U-shaped branch pipe 511 while squeezing the baffle plate 513 to rotate along the support block 512. When the rear nozzle 516 starts to work, the water pressure in the U-shaped branch pipe 511 decreases. At this time, the magnet 523 attracts the baffle plate 524, so that the front nozzle 516 stops spraying water. Since there is no water flow, the buzzer 525 stops working and stops the alarm.

[0069] Step 2: Water is injected into the water tank 41 through the inlet pipe 47 of the irrigation regulating device 4. At this time, the electric valve 3 42 on the connecting pipe 44 is opened and the water flows into the pipe 2 43 through the connecting pipe 44. When the plants are densely planted, the electric valve 46 is opened to drive the valve ball 45 to rotate, so that the water flows into the U-shaped pipe 1 to supply water to the device. When the plants are sparsely planted, the electric valve 46 is turned to drive the valve ball 45 to rotate, so that the water flows into the left or right end of the U-shaped pipe 1.

[0070] Step 3: Open the electric valve 24 on pipe 23 to allow water to flow into the box 21 through pipe 23. When enough water is added, close the electric valve 24. At this time, start the motor 22. The output end of the motor 22 drives the rotating roller 27 to rotate. The rotation of the rotating roller 27 drives the stirring plate 26 to rotate, so that the fertilizer and water are fully mixed. Open the electric valve 25 to deliver the liquid of fertilizer and water to the plant through the connecting pipe 44.

[0071] Step 4: By rotating the wheel 35 of the feeding device 3, the gear 37 is driven to rotate. The rotation of the gear 37 causes the sealing plate 36 to move up and down in the slot 38 opened on the box 21. The movement of the sealing plate 36 causes the feed inlet 39 to move, so that the feed inlet 39 is connected to the feeding pipe 34. Fertilizer is poured into the feeding funnel 32 and flows into the box 21 along the feeding pipe 34.
