Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation technology, specifically to a water-saving irrigation device based on smart agriculture. Background Technology

[0002] Agricultural irrigation refers to the technical measures of artificially supplementing crops with water. It is mainly used in areas with insufficient natural rainfall to ensure normal crop growth and achieve high and stable yields. Irrigation uses systems such as canals and pipelines to transport water sources (such as groundwater and river water) to farmland, regulate soil moisture, temperature and nutrients, thereby improving land productivity. Agricultural irrigation requires laying pipes in the farmland before irrigation operations. During irrigation, operators need to adjust the length of the pipes according to the humidity of the farmland. Currently, the pipe length is usually adjusted by disassembling the pipes, and operators need to reel in the disassembled pipes in time. This results in operators having to constantly adjust the pipes during irrigation, increasing the labor intensity of the operation. Summary of the Invention

[0003] The purpose of this invention is to provide a water-saving irrigation device based on smart agriculture to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a water-saving irrigation device based on smart agriculture, comprising a caster wheel bracket, a connecting plate fixedly connected to the bottom of the inner wall of the caster wheel bracket, and irrigation components disposed on the surface of the caster wheel bracket; The irrigation component includes a straight wheel frame, a limit frame fixedly connected to the top of the straight wheel frame, a fan-shaped nozzle mounted on the top of the limit frame, a water pipe inserted into the lower end of the fan-shaped nozzle, a limit rod fixedly connected to the surface of the straight wheel frame, a support ring fixedly connected to the upper surface of the universal wheel bracket, a roller inserted into the surface of the support ring, a positioning ring inserted into the surface of the roller, a winding frame fixedly connected to the surface of the positioning ring, a groove formed on the surface of the winding frame, a water inlet pipe fixedly connected to the inner wall of the winding frame, a connecting pipe rotatably connected to the end of the water inlet pipe, a round hole frame fixedly connected to the lower surface of the universal wheel bracket, a power unit fixedly connected to the top of the round hole frame, a drive wheel fixedly connected to the output end of the power unit, a fixing component provided at the end of the straight wheel frame and the universal wheel bracket that are close to each other, an insertion component provided at the top of the connecting plate, and a pressing component provided at the top of the connecting plate.

[0005] Furthermore, there are two universal wheel brackets, which are symmetrically arranged with the connecting plate as the center. The straight wheel bracket is located at one end of the two universal wheel brackets that are close to each other. The end of the water pipe away from the fan-shaped nozzle passes through the limiting rod and extends to the outer end of the limiting rod. The water pipe is wound inside the winding frame. The end of the water pipe away from the fan-shaped nozzle is connected to the top of the water inlet pipe.

[0006] Furthermore, the end of the water inlet pipe away from the water pipe passes through the caster bracket and extends to the outer end of the caster bracket; the surface of the drive wheel meshes with the inner wall of the groove; the bottom of the straight wheel bracket is located above the bottom of the caster bracket; the end of the fan-shaped nozzle extends to the outer end of the limiting frame; and the winding frame is located at the end of the two caster brackets that are close to each other.

[0007] Furthermore, the fixing component includes a slide rail frame, the surface of which is fixedly connected to the inner wall of the caster wheel bracket. An installation block is slidably connected to the inner wall of the slide rail frame. A linkage frame is fixedly connected to the surface of the installation block. The bottom of the linkage frame is fixedly connected to the top of the limiting rod. A fixing frame is fixedly connected to the top of the slide rail frame. An elastic rod is fixedly connected to the top of the inner wall of the fixing frame. An inclined block is fixedly connected to the bottom of the elastic rod. A synchronization plate is fixedly connected to the lower surface of the elastic rod.

[0008] Furthermore, there are two slide rails, which are symmetrically arranged around the linkage frame. The bottom of the inclined block passes through the slide rail and extends into the interior of the slide rail.

[0009] Furthermore, the surface of the mounting block is in contact with the surface of the inclined block, the inclined surface of the inclined block is located at the end of the inclined block away from the mounting block, and the synchronization plate is located above the linkage frame.

[0010] Furthermore, the plug-in component includes an elastic frame, the bottom of which is fixedly connected to the top of the connecting plate, a lifting plate fixedly connected to the top of the elastic frame, a conical plug rod fixedly connected to the end of the lifting plate, a step plate fixedly connected to the surface of the lifting plate, and a friction plate fixedly connected to the upper surface of the conical plug rod.

[0011] Furthermore, the bottom of the conical insert rod penetrates through the circular hole frame and extends to the outer bottom end of the circular hole frame. There are two conical insert rods. The surface of the conical insert rod is slidably connected to the inner wall of the circular hole frame. The end of the insert plate away from the lifting plate extends to the bottom of the lifting plate. The top of the friction plate contacts the surface of the positioning ring.

[0012] Furthermore, the extrusion component includes an inclined plate, the end of which is hinged to the surface of the lifting plate, a cylindrical rod is sleeved on the end of the inclined plate away from the lifting plate, a vertical plate is fixedly connected to the bottom of the cylindrical rod, a sliding plate is fixedly connected to the lower surface of the vertical plate, and a sliding hole frame is fixedly connected to the top of the connecting plate.

[0013] Furthermore, the end of the vertical plate away from the slide plate contacts the surface of the linkage frame, the top of the slide plate contacts the top of the connecting plate, and the surface of the slide plate is slidably connected to the inner wall of the sliding hole frame.

[0014] The present invention has the following beneficial effects: This invention inserts the mounting block into the slide rail frame, then uses an inclined block to limit the mounting block. After the mounting block is installed, it limits the straight wheel frame, improving the ease of assembly. As the mounting block moves into the slide rail frame, it pushes the vertical plate through the linkage frame. The vertical plate, in turn, pushes the sliding plate to move inside the sliding hole frame. The sliding plate and the sliding hole frame cooperate to improve the stability of the vertical plate during movement. When the vertical plate moves, it pushes the cylindrical rod to press against the inclined plate. After the inclined plate is under pressure, it pushes the lifting plate to move upward, thereby using the lifting plate to pull out the conical rod. The mounting block limits the conical rod, ensuring that it remains suspended as the universal wheel bracket moves, thus avoiding affecting the movement of the universal wheel bracket. After the lifting plate is limited by the inclined plate, the elastic frame pulls down the lifting plate with a downward retraction force. The lifting plate presses against the vertical plate through the inclined plate. At this time, the vertical plate, through the linkage frame, pushes the mounting block to press against the inclined block, improving the stability of the mounting block after installation.

[0015] When the lifting plate moves upward, it pushes the friction plate to press against the positioning ring, thereby fixing the winding frame through the positioning ring. This prevents the water pipe from loosening due to the rolling of the winding frame when the universal wheel bracket moves, improving the stability of the winding frame after winding the water pipe. When the mounting block separates from the slide frame, the lifting plate uses the elasticity of the elastic frame to push the conical rod downward. The conical rod uses the elasticity of the elastic frame to insert into the farmland and limit the universal wheel bracket, improving the stability of the universal wheel bracket supporting the winding frame. A step plate is provided on the surface of the lifting plate, allowing the operator to easily press the conical rod by stepping on it, so that the conical rod can be better inserted into the farmland to limit the universal wheel bracket.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-9 As shown, the present invention is a water-saving irrigation device based on smart agriculture, including a universal wheel bracket 1, a connecting plate 2 fixedly connected to the bottom of the inner wall of the universal wheel bracket 1, and an irrigation component 3 provided on the surface of the universal wheel bracket 1. The irrigation component 3 includes a straight wheel frame 10, a limit frame 12 fixedly connected to the top of the straight wheel frame 10, a fan-shaped nozzle 13 mounted on the top of the limit frame 12, a water pipe 14 inserted into the lower end of the fan-shaped nozzle 13, a limit rod 11 fixedly connected to the surface of the straight wheel frame 10, a support ring 22 fixedly connected to the upper surface of the universal wheel bracket 1, a roller 23 inserted into the surface of the support ring 22, a positioning ring 21 inserted into the surface of the roller 23, a winding frame 19 fixedly connected to the surface of the positioning ring 21, a groove 20 formed on the surface of the winding frame 19, a water inlet pipe 18 fixedly connected to the inner wall of the winding frame 19, a connecting pipe 24 rotatably connected to the end of the water inlet pipe 18, and a round hole frame 16 fixedly connected to the lower surface of the universal wheel bracket 1. A power unit 15 is fixedly connected, and a drive wheel 17 is fixedly connected to the output end of the power unit 15. The winding frame 19 is supported by the universal wheel bracket 1, which facilitates the transportation of the winding frame 19 to the farmland through the universal wheel bracket 1. After the universal wheel bracket 1 is placed at the edge of the farmland, it is fixed by the plug-in component 5 to improve the stability of the universal wheel bracket 1 during operation. The water inlet pipe 18 is connected to the water outlet of the pumping device through the connecting pipe 24. The river water pumped by the pumping device enters the water pipe 14 through the water inlet pipe 18 for irrigation. A fixing component 4 is provided at the end of the straight wheel frame 10 and the universal wheel bracket 1 that are close to each other. A plug-in component 5 is provided on the top of the connecting plate 2, and a pressing component 6 is provided on the top of the connecting plate 2.

[0022] There are two universal wheel brackets 1, which are symmetrically arranged with the connecting plate 2 as the center. The straight wheel bracket 10 is located at the end of the two universal wheel brackets 1 that are close to each other. The end of the water pipe 14 away from the fan-shaped nozzle 13 passes through the limiting rod 11 and extends to the outer end of the limiting rod 11. The water pipe 14 is wound inside the winding frame 19. After the water pumping device is started, the straight wheel bracket 10 is pulled out from the inside of the fixed part 4. The bottom of the straight wheel bracket 10 contacts the farmland. At this time, the straight wheel bracket 10 is pushed to move to the other end of the farmland. When the straight wheel bracket 10 is placed in the corresponding position, the water pumping device is started. The river water inside the water pipe 14 enters the fan-shaped nozzle 13. The fan-shaped nozzle 13 sprays the river water in a fan shape to irrigate the farmland. The straight wheel bracket 10 supports the fan-shaped nozzle 13, so no operator is needed to support it during irrigation. The end of the water pipe 14 away from the fan-shaped nozzle 13 is connected to the top of the water inlet pipe 18.

[0023] The end of the inlet pipe 18 away from the water pipe 14 passes through the universal wheel bracket 1 and extends to the outer end of the universal wheel bracket 1. The surface of the drive wheel 17 meshes with the inner wall of the groove 20. The bottom of the straight wheel bracket 10 is located above the bottom of the universal wheel bracket 1. When the power unit 15 is in operation, it drives the winding frame 19 to rotate through the meshing of the drive wheel 17 and the groove 20. The winding frame 19 rotates on the surface of the support ring 22 through the positioning ring 21 and the roller 23. When the winding frame 19 rotates, it winds up the water pipe 14. When the water pipe 14 is wound up, it will pull the straight wheel bracket 10 towards the universal wheel bracket 1 through the limit rod 11, so that the fan-shaped nozzle 13 can irrigate the farmland during the movement, improving the convenience of farmland irrigation. The end of the fan-shaped nozzle 13 extends to the outer end of the limit frame 12. The winding frame 19 is located at the end of the two universal wheel brackets 1 that are close to each other.

[0024] The fixed component 4 includes a slide rail frame 30. The surface of the slide rail frame 30 is fixedly connected to the inner wall of the universal wheel bracket 1. An installation block 35 is slidably connected to the inner wall of the slide rail frame 30. A linkage frame 33 is fixedly connected to the surface of the installation block 35. The bottom of the linkage frame 33 is fixedly connected to the top of the limiting rod 11. A fixing frame 31 is fixedly connected to the top of the slide rail frame 30. An elastic rod 32 is fixedly connected to the top of the inner wall of the fixing frame 31. An inclined block 36 is fixedly connected to the bottom of the elastic rod 32. A synchronization plate 34 is fixedly connected to the lower surface of the elastic rod 32. After the straight wheel bracket 10 is lifted, the installation block 35 is inserted into the interior of the slide rail frame 30. The slide rail frame 30 limits the installation block 35. When the installation block 35 moves into the interior of the slide rail frame 30, it will squeeze the inclined block 36 to move upward. When the installation block 35 separates from the inclined block 36, the inclined block 36 enters the interior of the slide rail frame 30 using the elasticity of the elastic rod 32 to limit the installation block 35.

[0025] There are two slide rails 30, which are symmetrically arranged with the linkage frame 33 as the center. The bottom of the inclined block 36 passes through the slide rail 30 and extends into the interior of the slide rail 30.

[0026] When the surface of the mounting block 35 contacts the surface of the inclined block 36, and the straight wheel frame 10 needs to be removed, the synchronous plate 34 is pulled upward. The synchronous plate 34 pushes the inclined block 36 to the outer end of the slide frame 30 through the elastic rod 32. At this time, the mounting block 35 can be removed to complete the disassembly of the straight wheel frame 10. The inclined surface of the inclined block 36 is located at the end of the inclined block 36 away from the mounting block 35, and the synchronous plate 34 is located above the linkage frame 33.

[0027] The insertion component 5 includes an elastic frame 42, the bottom of which is fixedly connected to the top of the connecting plate 2. A lifting plate 43 is fixedly connected to the top of the elastic frame 42. A conical rod 40 is fixedly connected to the end of the lifting plate 43. A stepping plate 44 is fixedly connected to the surface of the lifting plate 43. A friction plate 41 is fixedly connected to the upper surface of the conical rod 40. When the mounting block 35 moves to the outer end of the slide frame 30, the elastic frame 42 uses its elasticity to push the lifting plate 43 downward. When the lifting plate 43 moves downward, it pushes the conical rod 40 into the farmland through pressure. The conical rod 40 limits the universal wheel bracket 1, improving the stability of the universal wheel bracket 1 during operation. The operator can also press the conical rod 40 through the stepping plate 44, so that the conical rod 40 can be stably inserted into the farmland to limit the universal wheel bracket 1.

[0028] The bottom of the conical insert 40 passes through the circular hole frame 16 and extends to the bottom outer end of the circular hole frame 16. There are two conical inserts 40. The surface of the conical insert 40 is slidably connected to the inner wall of the circular hole frame 16. The end of the step plate 44 away from the lifting plate 43 extends to the bottom of the lifting plate 43. The top of the friction plate 41 contacts the surface of the positioning ring 21.

[0029] The extrusion component 6 includes an inclined plate 50. When the mounting block 35 moves into the slide frame 30, the linkage frame 33 contacts the vertical plate 51 and pushes the vertical plate 51 to move towards the surface of the connecting plate 2. When the vertical plate 51 moves, it pushes the slide plate 53 to slide inside the sliding hole frame 54, improving the stability of the vertical plate 51 during movement. When the vertical plate 51 moves, it extrudes the lifting plate 43 through the inclined plate 50. The inclined plate 50 pushes the lifting plate 43 to move upward, pulling the conical rod 40 upward, so that the bottom of the conical rod 40 is higher than the bottom of the universal wheel bracket 1. The end of the inclined plate 50 is hinged to the surface of the lifting plate 43. A cylindrical rod 52 is sleeved on the end of the inclined plate 50 away from the lifting plate 43. The bottom of the cylindrical rod 52 is fixedly connected to the vertical plate 51. The lower surface of the vertical plate 51 is fixedly connected to the slide plate 53. The top of the connecting plate 2 is fixedly connected to the sliding hole frame 54.

[0030] The end of the vertical plate 51 away from the slide plate 53 contacts the surface of the linkage frame 33, the top of the slide plate 53 contacts the top of the connecting plate 2, and the surface of the slide plate 53 is slidably connected to the inner wall of the sliding hole frame 54.

[0031] In use, the universal wheel bracket 1 supports the winding frame 19, facilitating its transport to the farmland. After placing the universal wheel bracket 1 at the edge of the farmland, it is secured using the plug-in component 5 to improve its stability during operation. The water inlet pipe 18 is connected to the outlet of the pumping device via the connecting pipe 24. The river water pumped by the pumping device enters the water pipe 14 through the water inlet pipe 18 for irrigation. After starting the pumping device, the straight wheel frame 10 is pulled out from inside the fixing component 4, with its bottom in contact with the farmland. The straight wheel frame 10 is then pushed to the other end of the farmland. Once the straight wheel frame 10 is in the corresponding position, the pumping device is started. The river water inside enters the fan-shaped sprinkler head 13, which sprays the water in a fan shape to irrigate the farmland. The fan-shaped sprinkler head 13 is supported by a straight wheel frame 10, eliminating the need for operator support during irrigation and reducing labor intensity. The operator adjusts the speed of the power unit 15 according to the humidity of the farmland. During operation, the power unit 15 drives the winding frame 19 to rotate through the engagement of the drive wheel 17 and the groove 20. The winding frame 19 rotates on the surface of the support ring 22 via the positioning ring 21 and the roller 23. As the winding frame 19 rotates, it winds up the water pipe 14. During winding, the water pipe 14 pulls the straight wheel frame 10 towards the universal wheel bracket 1 via the limit rod 11, allowing the fan-shaped sprinkler head 13 to irrigate the farmland during movement. Irrigation treatment is carried out to improve the convenience of farmland irrigation. The moving speed of the straight wheel frame 10 is adjusted according to the humidity of the farmland to avoid over-irrigation and waste of water resources, thereby improving water conservation. The limiting rod 11 limits the water pipe 14 to the lower surface of the straight wheel frame 10 to prevent the top of the limiting frame 12 from tipping over due to tension, thus improving the stability of the fan-shaped nozzle 13 during irrigation. The straight wheel frame 10 can only move in a straight line, improving the stability of the straight wheel frame 10 during movement and preventing the straight wheel frame 10 from tilting significantly as it moves with the water pipe 14. After lifting the straight wheel frame 10, the mounting block 35 is inserted into the slide frame 30. The slide frame 30 limits the mounting block 35, and the mounting block 35 moves into the slide frame 30. When the inclined block 36 is squeezed upwards, the mounting block 35 separates from the inclined block 36. The inclined block 36 uses the elasticity of the elastic rod 32 to enter the interior of the slide frame 30 and limit the mounting block 35, facilitating the transport of the universal wheel bracket 1 and the straight wheel frame 10 together and improving their convenience during transfer. When the straight wheel frame 10 needs to be removed, the synchronous plate 34 is pulled upwards. The synchronous plate 34 pushes the inclined block 36 to the outer end of the slide frame 30 through the elastic rod 32. At this time, the mounting block 35 can be removed to complete the disassembly of the straight wheel frame 10. When the mounting block 35 moves to the outer end of the slide frame 30, the elastic frame 42 uses its elasticity to push the lifting plate 43 downwards. When the lifting plate 43 moves downwards, it pushes the conical insert rod 40 into the farmland through pressure.The conical insert rod 40 is used to limit the universal wheel bracket 1, improving its stability during operation. The operator can also press the conical insert rod 40 using the step plate 44, ensuring its stable insertion into the farmland and limiting the universal wheel bracket 1. When the mounting block 35 moves into the sliding frame 30, the connecting frame 33 contacts the vertical plate 51 and pushes it towards the surface of the connecting plate 2. During this movement, the vertical plate 51 pushes the sliding plate 53 to slide inside the sliding hole frame 54, improving its stability. As the vertical plate 51 moves, it presses against the lifting plate 43 via the inclined plate 50, which in turn pushes the lifting plate 43 upwards, pulling the conical insert rod 40 upwards. This ensures the bottom of the conical insert rod 40 is higher than the bottom of the universal wheel bracket 1, preventing it from interfering with the movement of the universal wheel bracket 1 and improving its ease of use.
