Description

Technical Field

[0001] This invention relates to the field of irrigation technology, and in particular to a water-saving irrigation device for agricultural planting. Background Technology

[0002] In agricultural production, irrigation is a core element ensuring normal crop growth. Reducing water evaporation and improving water resource utilization efficiency during irrigation have always been key research areas in water-saving agriculture. Traditional irrigation methods such as flood irrigation and surface sprinkler irrigation expose water directly to the soil surface and air, resulting in high evaporation losses. To reduce irrigation water evaporation, existing technologies have developed water-saving irrigation solutions such as drip irrigation and seepage irrigation. However, these solutions mostly employ fixed pipeline installations, leading to high initial installation costs. Furthermore, once the pipelines are fixed in location, they cannot be flexibly moved, making them unsuitable for scattered plots, crop rotation, and irregular planting scenarios such as hilly and mountainous areas.

[0003] To address the demand for deep water supply, some soil-penetrating irrigation equipment has emerged in the industry. This equipment achieves deep water injection by inserting the water injection pipe into the soil, reducing evaporation loss to some extent. However, such equipment still has significant shortcomings: First, its function is limited, only capable of water injection. The soil breaking process during irrigation loosens the surface layer and increases porosity, leading to rapid evaporation and loss of surface moisture after irrigation. The lack of simultaneous ridging and covering with soil to retain moisture further hinders the continuous improvement of water-saving effects. If ridging and covering are added separately, it increases operational and time costs, resulting in low field efficiency. Second, existing soil-penetrating irrigation equipment has poor adaptability to soil breaking and penetration. It faces significant resistance in compacted or hard soils, and the injection components are easily blocked or damaged by soil clods. Furthermore, the penetration depth and irrigation range are difficult to adjust flexibly according to crop type and soil moisture conditions, resulting in insufficient versatility. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of large evaporation loss, insufficient mobility, single function, limited water retention effect and poor soil adaptability of existing equipment in practical applications, and to propose a water-saving irrigation device for agricultural planting.

[0016] Compared with the prior art, the present invention provides a water-saving irrigation device for agricultural planting, which has the following beneficial effects.

[0017] 1. This invention uses an electric vehicle as the main vehicle for transportation, eliminating the need for fixed pipelines. It can be flexibly adapted to scattered plots and crop rotation scenarios. By driving two soil-breaking plates outward through an electric push rod, it forms an inclined soil-insertion posture, allowing the water outlet of the spray pipe to directly approach the crop roots for deep irrigation, greatly reducing surface evaporation and lateral seepage, and significantly improving irrigation water utilization.

[0018] 2. In this invention, the surface compacted soil is broken up at high speed by the soil crusher before operation, which reduces the soil-breaking plate's resistance to entering the soil and avoids large pieces of hard soil from impacting the internal pipe components. During the soil-entry stage, the rectangular plate closes inward and forms a closed slope together with the soil-breaking plate. This reduces the soil-entry friction area while sealing the pipe opening, preventing soil from entering and causing pre-blockage. This provides pre-protection for the irrigation components and improves adaptability to field conditions.

[0019] 3. This invention uses a second electric push rod to drive a double lever to form a differential stroke output. Combined with the meshing transmission of gears and racks, it drives the water distribution valve to deflect, automatically completing the flow path docking and switching with the spray pipe and vertical pipe. The pure mechanical linkage structure does not require additional electric control valves, making it more stable in high humidity and dusty field environments, with higher docking accuracy and sealing reliability.

[0020] 4. In this invention, the water distribution valve has a built-in flow sensor to monitor the pipeline flow status in real time. It can accurately identify different working conditions such as spray pipe blockage, vertical pipe rupture, and simultaneous blockage of two lines, and automatically match the corresponding treatment program. For pipeline blockage, it sequentially triggers a triple blockage removal mechanism of mechanical puncture, high-pressure flushing, and swing dredging. The rectangular plate drives the bent rod to puncture the pipe opening and loosen the blockage. The vertical pipe outputs high-speed water flow for internal flushing. With the help of the electric push rod, the soil breaking plate swings back and forth to throw away mud. It can automatically clear the blockage of conventional pipelines without disassembling the machine, which greatly shortens the downtime for field maintenance and reduces the intensity of manual blockage removal operations.

[0021] 5. This invention adopts a plug-in clamp connection structure. During daily operation, the connecting bolts are stored inside the frame to prevent mud and water from corroding the threads. When multiple blockages occur, the box is rotated so that the bolt ends are turned out to an easily operable position, which can realize the overall side sliding out and quick replacement of the earth-breaking operation component, significantly shortening the fault repair time.

[0022] 6. In this invention, irrigation and soil removal are carried out simultaneously by a disc with an adjustable tilt angle driving a soil-lifting plate to move soil back and forth. This, together with soil-lifting wheels symmetrically arranged at the rear end, completes the ridging and covering of soil. The irrigated soil is gathered towards the crop roots, reducing surface water evaporation. The tilt angle of the disc can be adjusted by the threaded rod to change the soil-lifting amplitude, adapting to different ridge spacing planting needs, realizing integrated irrigation and moisture conservation operations, and further enhancing the water-saving and seedling protection effects.

[0023] Other advantages, objectives and features of the invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be learned from practice of the invention.

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] Reference Figures 1-16An agricultural irrigation system includes an electric vehicle 1, which serves as the main vehicle for movement and can flexibly move along the planting ridges without the need for fixed pipelines. It is suitable for scattered plots and crop rotation scenarios. A water tank 2 is installed on the upper part of the electric vehicle 1's frame. A frame 3 is located at the bottom of the electric vehicle 1, and two hydraulic rods 8 are symmetrically arranged on the top of the frame 3. The cylinder end of each hydraulic rod 8 is fixed to the bottom of the electric vehicle 1's frame, and the piston rod end is fixed to the top surface of the frame 3. The synchronous extension and retraction of the two hydraulic rods 8 allows the frame 3 to rise and fall smoothly in the vertical direction, thereby adjusting the depth of soil penetration. A soil-breaking component 4 is located on the front interior of the frame 3, comprising several radially extending soil-breaking claws. In this state, the soil-breaking component 4 is driven to rotate at high speed by the matching drive mechanism. As the equipment moves forward, the soil-breaking claws first contact and break the surface compacted soil, breaking the hard crust of the ground and refining and loosening the soil clods. On the one hand, this significantly reduces the soil penetration resistance of the subsequent soil-breaking plate 24, and on the other hand, it prevents large pieces of hard soil from directly impacting the soil-breaking plate 24 and internal pipeline components, thus providing front-end protection for the irrigation components. The rear side of the soil-breaking component 4 is rotatably connected to the box 19, and the rear side of the box 19 is equipped with two soil-breaking plates 24. The two soil-breaking plates 24 are symmetrically arranged about the center line of the box 19 as the axis of symmetry. In the non-operating state, the hydraulic rod 8 drives the frame 3 to lift upward, the box 19 deflects upward, and simultaneously drives the two soil-breaking plates 24 to rotate upward and retract, completing the storage and preventing soil breaking during the movement of the equipment. When the plate 24 scrapes against the ground and accumulates soil, and enters the irrigation operation, the hydraulic rod 8 drives the frame 3 to move downwards, and the box 19 swings down to reset. The two soil-breaking plates 24 first move down to a vertical position to complete the soil insertion operation. Then, the internal components of the box 19 drive the two soil-breaking plates 24 to rotate outwards synchronously, forming an inclined soil insertion posture that is wider at the bottom and narrower at the top, so that the water outlet directly acts on the area around the crop roots to achieve precise root irrigation. Each soil-breaking plate 24 is equipped with a liquid distribution pipe 7, which extends along the length of the soil-breaking plate 24. The bottom of the liquid distribution pipe 7 is equipped with a water distribution valve 29. The liquid distribution pipe 7 and the water distribution valve 29 are connected to each other. They can be connected by a threaded interface or other methods, which are not limited here. The bottom of the water distribution valve 29 is equipped with a spray pipe 30. The water distribution valve 29 can independently control the on / off state of the corresponding spray pipe 30. A vertical pipe 32 is provided on the outside of the water distribution valve 29, which can also independently control the on / off state of the corresponding spray vertical pipe 32. A flow sensor is installed inside the water distribution valve 29 to monitor the flow rate inside. If the flow rate decreases or reaches zero during irrigation, it indicates a blockage at the bottom of the spray pipe 30 or the bottom of the vertical pipe 32. A rectangular plate 25 is rotatably connected to the inner side of the soil-breaking plate 24. As the soil-breaking plate 24 is inserted downwards into the soil along with the frame 3, the rectangular plate 25 rotates inwards and abuts against the inner wall of the soil-breaking plate 24, forming an inclined surface. This reduces the friction area for insertion into the soil, facilitating insertion.Simultaneously, the bottom of the soil-breaking plate 24 is sealed. A bent rod 33 is provided on the inner side of the rectangular plate 25. The bent rod 33 can move as the rectangular plate 25 rotates. The curvature of the bent rod 33, combined with the rotation of the rectangular plate 25, allows the bent rod 33 to be inserted into the bottom of the spray pipe 30. The movement of the rectangular plate 25 enables puncture and drainage of the bottom of the spray pipe 30.

[0044] A second electric push rod 27 is fixedly connected to the top of the soil-breaking plate 24. A control rod 42 is fixedly connected to the bottom of the second electric push rod 27. The control rod 42 can rise and fall with the extension and retraction of the second electric push rod 27. A first cylindrical rod 48 and a second cylindrical rod 49 are fixedly connected to one side of the bottom of the control rod 42. A first lever 43 is slidably connected to the outer side of the first cylindrical rod 48. The middle part of the first lever 43 is rotatably connected to the soil-breaking plate 24. A fixed rod 52 is slidably connected to the other end of the soil-breaking plate 24. A first slider 46 is fixedly connected to the inner side of the fixed rod 52. A second lever 44 is slidably connected to the outer side of the second cylindrical rod 49. One side of the second lever 44 is rotatably connected to the soil-breaking plate 24. A second slider 47 is slidably connected to the other side of the second lever 44. The inner sides of both the first slider 46 and the second slider 47 are slidably connected to the soil-breaking plate 24. Figure 10 As shown, the hinge point of the first lever 43 is close to the point of force application, making it a lever that requires more effort. The hinge point of the second lever 44 is far from the point of force application, making it a lever that requires less effort. When the control rod 42 moves upward, it drives the first cylindrical rod 48 and the second cylindrical rod 49 to move. The other side of the first lever 43 and the second lever 44 will rotate downward. Since the hinge points of the two levers are different, the first lever 43 will drive the slidingly connected fixed rod 52 and the first slider 46 to move vertically downward. The second lever 44 will drive the slidingly connected second slider 47 to move vertically downward. The moving speed and moving stroke of the fixed rod 52 and the first slider 46 are greater than the moving stroke of the second slider 47.

[0045] A turntable 51 and a third gear 54 are linearly arranged on the outer side of the fixed rod 52. The third gear 54 is rotatably connected to the fixed rod 52, and its outer side is fixedly connected to the water distribution valve 29. A guide rod 50 is fixedly connected to the surface of the water distribution valve 29. A limiting groove 45 is provided on the inner wall of the soil-breaking plate 24. The shape of the limiting groove 45 consists of a vertical line and an arc. The end of the guide rod 50 is slidably connected to the limiting groove 45, and the inner side of the guide rod 50 is fixedly connected to the turntable 51. The turntable 51 is rotatably connected to the fixed rod 52. The water distribution valve 29 drives the guide rod 50 to rotate, and the guide rod 50 can drive the turntable 51 to rotate on the surface of the fixed rod 52. A coil spring 53 is fixedly connected to the middle of the fixed rod 52, and the other end of the coil spring 53 is fixedly connected to the turntable 51. When the turntable 51 rotates, the coil spring 53 can be put into a charged state. Figure 12The coil spring 53 is in the stored state. A third rack 55 meshes with one side of the third gear 54. The side wall of the third rack 55 is fixedly connected to the side wall of the soil-breaking plate 24. A retaining ring 56 is fixedly connected to the outer end of the second slider 47. The inner side of the retaining ring 56 is fixedly connected to the spray pipe 30. When the first slider 46 and the fixed rod 52 move downwards, the third rack 55 will cause the meshing third gear 54 to rotate counterclockwise, thus causing the water distribution valve 29 to rotate counterclockwise. At this time, the guide rod 5... The device 0 will move along an arc-shaped trajectory, while the coil spring 53 gradually relaxes, assisting in rotating the turntable 51, causing the water distribution valve 29 to rotate vertically downwards, and then continue to move. Because the travel of the retaining ring 56 is short, the water distribution valve 29 will align with the spray pipe 30 after moving vertically downwards. The bottom of the inner side of the water distribution valve 29 is provided with a connecting pipe 31, and the bottom of the connecting pipe 31 is slidably connected to the spray pipe 30. The connecting pipe 31 is inserted into the spray pipe 30, and then the internal irrigation of the soil begins.

[0046] A connecting rod 28 is hinged to the outer side of the second slider 47. The bottom of the connecting rod 28 is rotatably connected to the rectangular plate 25. When the second slider 47 moves downward, it can drive the connecting rod 28 to shift downward, thereby pushing the rectangular plate 25 to rotate outward, pushing away the local soil to facilitate deep irrigation. A triangular plate 57 is fixedly connected to the bottom outer side of the second electric push rod 27. A third cylindrical rod 61 is slidably connected to the top outer side of the triangular plate 57. A sliding ring 60 is fixedly connected to the inner side of the third cylindrical rod 61. A connector 62 is fixedly connected to the bottom of the sliding ring 60. A support rod 58 is slidably connected to the top of the sliding ring 60. The outer side of the support rod 58 is fixedly connected to the soil-breaking plate 24. A tension spring 59 is fixedly connected to the top of the support rod 58. The other side of the tension spring 59 is fixedly connected to the sliding ring 60. The outer side of the connector 62 is interconnected with the vertical pipe 32. Figure 13 In the state shown, the second electric push rod 27 retracts, causing the fixedly connected triangular plate 57 to move upward. Under the action of the tension spring 59, the sliding ring 60 is pulled to move closer to the second electric push rod 27, causing the connector 62 to disconnect from the water distribution valve 29. The end of the connector 62 is tapered, which facilitates separation and docking, and there is no motion interference between the components.

[0047] The tops of the two liquid distribution pipes 7 are connected to a water pump 6. The side of the water pump 6 is fixedly connected to the electric vehicle 1. The top of the water pump 6 is connected to an inlet pipe 5. The top of the inlet pipe 5 is connected to a water tank 2. The bottom of the water tank 2 is fixedly connected to the top of the electric vehicle 1. The water tank 2 is made of corrosion-resistant plastic in one piece. The bottom is fixed to the carrying platform of the electric vehicle 1 by bolts and shock-absorbing pads. A water inlet is opened on the top surface of the water tank 2 to facilitate the operator to replenish the water source in real time. The irrigation liquid inside the water tank 2 flows into the inlet pipe 5 by its own weight. It is then transported to the booster water pump 6. After being pressurized, the water pump 6 divides the water flow into the two liquid distribution pipes 7. The water is then transported downwards from the liquid distribution pipes 7 to the two side water distribution valves 29. After the flow rate is regulated by the water distribution valves 29, the water is sent into the spray pipe 30 to complete the root irrigation. All the liquid distribution pipes 7 are made of high-pressure resistant and wear-resistant rubber hoses. The pipe body has good bending and deformation capabilities and can move up and down and deflect synchronously with the frame 3 and the soil breaking plate 24. The pipes will not crack or break due to mechanical movement.

[0048] One side of the soil crusher 4 is equipped with a pulley assembly 11. A drive shaft 13 is fixedly connected to the rear side of the pulley assembly 11. A first bevel gear 14 is fixedly connected to the outer side of the drive shaft 13. A second bevel gear 15 meshes with the front end of the first bevel gear 14. A motor 16 is fixedly connected to the front end of the second bevel gear 15. The inner side of the motor 16 is fixedly connected to the frame 3. During operation, after the motor 16 starts, it drives the second bevel gear 15 to rotate at high speed. Through the meshing transmission of the bevel gears, it drives the first bevel gear 14 and the coaxial drive shaft 13 to rotate synchronously. The drive shaft 13 further drives the pulley assembly 11 at the front end to rotate. Finally, the pulley assembly 11 drives the soil crusher 4 to rotate at high speed, and the soil crushing claw completes the surface soil crushing and loosening operation.

[0049] The box 19 is equipped with a first electric push rod 23 inside. The inner side of the first electric push rod 23 is fixedly connected to the box 19, and the outer side of the first electric push rod 23 is fixedly connected to a transmission rod 22. The extension and retraction of the first electric push rod 23 drives the transmission rod 22 to move left and right inside the box 19. The transmission rod 22 is slidably connected to the box 19. A first rack 17 is provided on the inner and outer sides of the transmission rod 22 respectively. A first gear 18 is meshed on the inner side of each rack 17. The rear side of the first gear 18 is connected to the soil breaking plate 24. The first gear 18 is rotatably connected to the box 19. The transmission rod 22 drives the two fixedly connected first racks 17 to move, thereby realizing that the two first gears 18 can rotate inward or outward at the same time, realizing the angle adjustment of the two soil breaking plates 24. After being inserted into the soil, they tilt outward at the same time. The tilted soil breaking plate 24 can facilitate irrigation of the roots of crops.

[0050] A second gear 20 is provided on one side of the box body 19. The front end of the second gear 20 meshes with a second rack 21. The top end of the second rack 21 is fixedly connected to the electric vehicle 1. The second gear 20 is rotatably connected to the frame 3. Two first locking rods 63 are fixedly connected to the outside of the box body 19. The two first locking rods 63 are symmetrically arranged about the center line of the box body 19. A second locking rod 64 is slidably connected to the outside of each first locking rod 63. The outside of the second locking rod 64 is rotatably connected to the frame 3. The outside of one of the second locking rods 64 is fixedly connected to the second gear 20. The first locking rods 63 and the second locking rods 64 are interlocked and fixedly connected by bolts. The frame 3 moves up and down, driving the second gear 20. The wheel 20 rises and falls. Since the position of the second rack 21 is fixed, the second gear 20 can rotate. The second gear 20 drives the second locking rod 64 to rotate, thereby rotating the box 19. When the flow sensor detects that the spray pipe 30 and the vertical pipe 32 are blocked, the frame 3 continues to move downward. Under the action of the second rack 21, it continues to rotate, so that the end of the bolt can rotate vertically downward and out of the inside of the frame 3. Then it is driven to the maintenance area for disassembly. The box 19 and the associated components are disassembled together. The first locking rod 63 and the second locking rod 64 are separated and can be directly slid off from the side, which is very convenient. The associated liquid distribution pipe 7 is disassembled and then connected to the new components.

[0051] A first disk 34 is rotatably connected to the middle of the drive shaft 13. The first disk 34 can tilt left and right and rotates with the drive shaft 13. An adjusting rod 35 is rotatably connected to one side of the first disk 34. The two sides of the adjusting rod 35 are hinged to the first disk 34 and the second disk 36, respectively. The second disk 36 is rotatably connected to the outer side of the adjusting rod 35. The second disk 36 is slidably connected to the drive shaft 13. The outer edge of the drive shaft 13 has a rectangular protrusion that matches the rectangular recess of the second disk 36, allowing the second disk 36 to slide on the surface of the drive shaft 13 while the drive shaft 13 drives the second disk 36 to rotate. An adjusting block 41 is slidably connected to the rear side of the second disk 36. A threaded rod 37 is threadedly connected to the inner side of the adjusting block 41. The outer side of the threaded rod 37 is rotatably connected to the frame 3. A sliding rod 38 is slidably connected to the outer side of the adjusting block 41. The outer side of the sliding rod 38 is fixedly connected to the frame 3. Rotating the threaded rod 37... 7 can drive the adjusting block 41 to move horizontally along the sliding rod 38. The adjusting block 41 pulls the second disc 36 to move outward. The second disc 36 pulls the adjusting rod 35 to drive the first disc 34 to tilt outward. The rear end of the first disc 34 is slidably connected to the protruding rod 39. The rear side of the protruding rod 39 is fixedly connected to the soil-pulling plate 40. The front end of the soil-pulling plate 40 is rotatably connected to the frame 3. When the tilted first disc 34 rotates, it will drive the slidably connected protruding rod 39 to swing left and right. The protruding rod 39 and the soil-pulling plate 40 form a force-multiplying lever, which can realize the reciprocating swing of the soil-pulling plate 40 to push the irrigated soil to both sides to form ridges. The tilt of the first disc 34 can be adjusted according to the spacing of the ridges on site. The rear end of the frame 3 is provided with two soil-pulling wheels 9. The two soil-pulling wheels 9 are symmetrically arranged with the center line of the frame 3 as the axis of symmetry. The two tilted soil-pulling wheels 9 work together to form ridges after the soil is irrigated, reducing the amount of water evaporation.

[0052] When in use: After the electric vehicle 1 travels to the target planting ridge, the two hydraulic rods 8 arranged symmetrically front and back extend synchronously, driving the frame 3 to move smoothly downward in the vertical direction, thereby adjusting the depth of the soil entry operation.

[0053] During the descent of frame 3, frame 3 drives the second gear 20 to move down and engage with the second rack 21 fixed at the bottom of electric vehicle 1, thereby driving the box 19 to deflect downward from the horizontal storage state to the vertical state, and simultaneously driving the soil-breaking plates 24 on both sides to turn into a vertical soil-entry posture.

[0054] At the same time, the motor 16 starts and drives the second bevel gear 15, the first bevel gear 14, the transmission shaft 13, and the pulley group 11 in sequence, which eventually drives the soil breaking component 4 to rotate at high speed. The soil breaking claw of the soil breaking component 4 first contacts and breaks the surface hard soil, breaks the hard shell of the ground and refines and loosens the soil clods. On the one hand, it greatly reduces the soil penetration resistance of the subsequent soil breaking plate 24, and on the other hand, it avoids large pieces of hard soil from directly impacting the soil breaking plate 24 and the internal pipeline components, thus forming a front protection for the irrigation components.

[0055] Before the soil-breaking plate 24 is inserted into the soil, the rectangular plate 25 rotates inward and abuts against the inner wall of the soil-breaking plate 24, forming a closed slope together with the soil-breaking plate 24. This reduces the friction area in the soil and facilitates the insertion of the soil-breaking plate 24 into the soil, while also sealing the bottom of the soil-breaking plate 24 to prevent soil from entering the spray pipe 30 and causing pre-blockage.

[0056] After the soil-breaking plate 24 is inserted into the soil to the set depth, the trenching and alignment process begins. The first electric push rod 23 inside the box 19 extends and pushes the transmission rod 22 to slide laterally along the box 19, driving the first racks 17 on both sides to move synchronously. This meshes and drives the two first gears 18 to rotate synchronously in opposite directions, causing the two soil-breaking plates 24 to deflect outwards synchronously, forming an inclined soil-insertion posture that is wider at the bottom and narrower at the top. This allows the water outlet to directly approach the periphery of the crop roots, achieving precise root irrigation, reducing water evaporation and lateral leakage, and improving water-saving efficiency.

[0057] Subsequently, the second electric push rod 27 retracts, causing the control rod 42 to move upward. The first cylindrical rod 48 and the second cylindrical rod 49 at the end of the control rod 42 respectively drive the first lever 43 and the second lever 44 to rotate around their respective hinge points. The hinge point of the first lever 43 is closer to the force-applying end, making it a force-multiplying lever, while the hinge point of the second lever 44 is farther from the force-applying end, making it a force-saving lever. The two form a differential output, causing the downward stroke of the fixed rod 52 and the first slider 46 to be greater than the downward stroke of the second slider 47. When the fixed rod 52 moves downward, the third gear 54, which is fitted on the outside of the fixed rod 52, moves along the third tooth fixed to the side wall of the soil-breaking plate 24. The meshing and rotation of bar 55 causes the water distribution valve 29 to deflect synchronously. The guide rod 50 on the surface of the water distribution valve 29 slides along the limiting groove 45 on the inner wall of the soil breaking plate 24. The inner side of the guide rod 50 drives the turntable 51 to rotate around the fixed rod 52. The coil spring 53 gradually relaxes and releases energy as the turntable 51 rotates, ensuring a smooth and impact-free rotation process. Finally, the connecting pipe 31 at the bottom of the water distribution valve 29 rotates to a vertically downward position. The coil spring 53 can assist the movement of the water distribution valve 29 in daily life without deflection. As the fixed rod 52 continues to move downward, the connecting pipe 31 and the spray pipe 30 form a relative displacement and are inserted into the spray pipe 30, completing the flow path sealing connection.

[0058] Simultaneously, the second slider 47, through the outer fixed retaining ring 56, drives the spray pipe 30 to move down synchronously with a small stroke, ensuring proper insertion in conjunction with the docking action. The downward movement of the second slider 47 also pushes the rectangular plate 25 outward through the connecting rod 28, clearing the surrounding soil to expose the irrigation space and preventing soil from directly blocking the spray nozzle. After the flow path docking is completed, the water pump 6 starts, and the irrigation liquid in the water tank 2 is pumped through the inlet pipe 5 into the two side distribution pipes 7, and then transported through the distribution pipes 7 to the water distribution valve 29. The water distribution valve 29 regulates the flow rate, and the liquid is then injected into the soil around the crop roots through the connecting pipe 31 and the spray pipe 30, completing deep and precise irrigation. The distribution pipe 7 uses a high-pressure resistant and wear-resistant rubber hose, which can move up, down, and deflect synchronously with the frame 3 and the soil-breaking plate 24, preventing pipe cracking or flow interruption due to mechanical pulling.

[0059] During irrigation, the flow sensor inside the water distribution valve 29 monitors the pipeline flow in real time. When a decrease or zero flow is detected, it is determined that mud blockage has occurred at the end of the spray pipe 30. The equipment automatically triggers a self-cleaning program, eliminating the need for manual disassembly and cleaning. First, the second electric push rod 27 reciprocates, driving the second slider 47 to move up and down, which in turn drives the rectangular plate 25 to open and close repeatedly via the connecting rod 28. When the rectangular plate 25 closes inward, the bent rod 33 on its inner side moves inward and inserts into the bottom of the spray pipe 30. Through a piercing action, it loosens the clumps of mud at the pipe opening. Repeated reciprocating motions can loosen and dislodge large blockages, creating conditions for subsequent hydraulic flushing. Subsequently, the water distribution valve 29 rotates to switch the flow path, disconnecting from the spray pipe 30 and connecting to the vertical pipe 32. The second electric push rod 27 extends, driving the control rod 42 downward. The third gear 54 meshes and rotates in the opposite direction along the third rack 55, causing the water distribution valve 29 to deflect in the opposite direction. The guide rod 50 slides back along the limiting groove 45, and the turntable 51 rotates in the opposite direction, causing the coil spring 53 to recharge. The side interface of the water distribution valve 29 rotates to align with the top of the vertical pipe 32. At the same time, the triangular plate 57 moves downward synchronously with the second electric push rod 27. The third cylindrical rod 61 slides along the inclined surface of the triangular plate 57, pushing the sliding ring 60 to slide outward along the support rod 58. The tension spring 59 is stretched, and the butt joint 62 at the bottom of the sliding ring 60 presses against the side interface of the water distribution valve 29, completing the sealed connection of the flow path of the vertical pipe 32.

[0060] After docking, water pump 6 continues to run. Due to the smaller diameter of vertical pipe 32, the water flow velocity and head increase. The high-speed water flow flows along the arc-shaped protrusion inside rectangular plate 25 towards the bottom of spray pipe 30. In the early stage of unblocking, rectangular plate 25 can be moved back and forth several times to push out the mud. Then, it is continuously shut off, and high-speed spraying of liquid from vertical pipe 32 is carried out. Water is stored inside the soil-breaking plate 24 to flush and disperse the loose mud inside the pipe. During the flushing process, the first electric push rod 23 reciprocates and extends synchronously, through transmission rod 22, first rack 17, and first gear. 18 drives the two soil-breaking plates 24 to swing back and forth at a small angle, causing the mud and water inside the spray pipe 30 and the cavity of the soil-breaking plate 24 to shake, enhancing the flushing and mud removal effect. The inwardly closed rectangular plate 25 and the soil-breaking plate 24 form an inclined deposition area. The sludge washed off is deposited at the inclined low position under the action of gravity and will not be deposited again at the opening of the spray pipe 30. After the flushing is completed, the rectangular plate 25 opens outward, and the sludge is naturally discharged by gravity. The soil-breaking plate 24 continues to swing to shake off the residual mud and water in the cavity. After the self-cleaning process is completed, normal irrigation is restored.

[0061] During the flushing and unblocking stage of the vertical pipe 32, the flow sensor continuously monitors the inlet water flow. If the flow suddenly increases, it indicates a rupture in the vertical pipe 32 area. The system immediately stops the flushing procedure and controls the water distribution valve 29 to rotate and reconnect to the spray pipe 30. If the spray pipe 30 is cleared at this time, normal root irrigation operations are resumed, prioritizing field irrigation progress and avoiding the risk of large-scale yield reduction. If the flow still returns to zero after switching to flushing the vertical pipe 32, it is determined that both the spray pipe 30 and the vertical pipe 32 are severely blocked and cannot be repaired by self-cleaning. The equipment enters the overall maintenance process. The electric vehicle 1 travels to the maintenance area, the hydraulic rod 8 continues to extend, the frame 3 feeds further downward, and the second gear 20 continues to mesh and rotate downward along the second rack 21, driving the second clamp. The rod 64 and the box 19 continue to deflect downwards, causing the ends of the fixing bolts at the connection between the first clamp rod 63 and the second clamp rod 64 to turn vertically downwards and rotate out from inside the frame 3 to a position that is easy to operate. After the operator loosens the fixing bolts, the box 19, together with the soil-breaking plates 24 on both sides, the internal pipelines and transmission components, can be slid out laterally as a whole. The first clamp rod 63 and the second clamp rod 64 are separated, and the liquid separator 7 connector is removed simultaneously. The entire disassembly of the faulty component can be completed. After replacing the new working component, the reverse operation can be used for quick reassembly, which greatly shortens the downtime for field maintenance. In normal operation, the connecting bolts are concealed and stored inside the frame 3, which can prevent mud and water from corroding the bolt threads, providing long-term protection and ensuring smooth disassembly and assembly during maintenance.

[0062] During normal irrigation, the equipment moves forward along the ridge. After irrigation, the rear mechanism completes ridging and soil covering, further improving water-saving effects. When the drive shaft 13 rotates, it drives the first disc 34 to rotate synchronously, and through the adjusting rod 35, it drives the second disc 36 to rotate synchronously. Rotating the threaded rod 37 can drive the adjusting block 41 to move horizontally along the sliding rod 38, pulling the second disc 36 to slide axially along the drive shaft 13. By adjusting the adjusting rod 35, the tilt angle of the first disc 34 is changed, thereby adjusting the soil-lifting amplitude. When the tilted first disc 34 rotates, it drives the soil-lifting plate 40 to swing back and forth through the convex rod 39, gathering the irrigated soil towards the crop roots. Together with the soil-lifting wheels 9 symmetrically arranged on both sides of the rear end of the frame 3, they complete ridging and soil covering, reducing the evaporation of surface soil moisture after irrigation and further improving water-saving and moisture-retention effects.
