Description

Technical Field

[0001] This invention relates to the field of farmland irrigation technology, specifically to a large-scale horizontal-moving sprinkler irrigation machine and irrigation system for farmland. Background Technology

[0002] A translational sprinkler is a type of sprinkler that consists of a long spray pipe supported by a dozen or so towers. It sprays while moving. Its movement is different from that of a center-pivot sprinkler, where the pipe rotates, while the pipe of a translational sprinkler moves laterally.

[0003] Chinese utility model patent CN208191708U discloses a translational sprinkler irrigation machine that can adjust the height of the bottom of the water outlet pipe from the ground and can also move fixed blocks to adjust the spacing to suit different crops.

[0004] Currently, for large areas of farmland, adjacent water pipes are often spliced ​​and fixed together. With prolonged use of the sprinkler system, the sealing between adjacent pipes is easily affected by vibration, wear, and other factors, leading to leaks and insufficient irrigation pressure, thus affecting the irrigation effect. Therefore, this invention proposes a large-scale horizontal-moving sprinkler system for farmland to solve the above problems. Summary of the Invention

[0031] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit 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.

[0032] Please see Figures 1 to 9 The present invention provides a technical solution:

[0033] Example 1: A large-scale horizontal-moving sprinkler irrigation machine for farmland includes: a water delivery pipe 1, a walking frame 2, and an anti-jump pressure plate 4.

[0034] Specifically, splicing pipes 11 are movably inserted into both ends of the water supply pipe 1. Annular gaskets 15 are provided at the joints between the splicing pipes 11 and the water supply pipe 1 to improve the sealing of the joint. The splicing pipes 11 can be horizontally displaced a certain distance along the length of the water supply pipe 1. A splicing flange 13 and a pressure-bearing collar 14 are fixedly installed at one end and the middle of the splicing pipe 11, respectively. The edge of the splicing flange 13 has holes. When the two splicing flanges 13 approach and fit together, they can be initially fixed together with bolts. A sealing ring is also provided on the surface of the splicing flange 13 to ensure the sealing between the two splicing flanges 13 and prevent liquid leakage.

[0035] Secondly, the traveling frame 2 is located on the outer side of the end of the water supply pipe 1. U-shaped sleeves 21 are fixedly installed on both sides of the traveling frame 2. A splicing insertion hole 22 corresponding to the inner cavity of the U-shaped sleeve 21 is opened through the middle of the traveling frame 2. The splicing insertion hole 22 allows the splicing flanges 13 on both sides of the traveling frame 2 to extend into the inner cavity of the splicing insertion hole 22 for splicing and fixing. U-shaped pad one 211 and U-shaped pad two 212 are fixedly installed on the inner wall of the U-shaped sleeve 21. The end of the water supply pipe 1 and the splicing pipe 11 respectively rest on U-shaped pad one. Inside U-shaped pad 211 and U-shaped pad 212, U-shaped pad 211 supports the end of water pipe 1, and U-shaped pad 212 supports splicing pipe 11, ensuring that water pipe 1 and splicing pipe 11 remain collinear and will not bend, thus preventing liquid leakage. A U-shaped side pressure plate 213 is fixedly installed on the side of U-shaped pad 212, and the U-shaped side pressure plate 213 horizontally presses against the pressure-bearing collar 14. The side of the U-shaped side pressure plate 213 is inclined, and its upper thickness is less than its lower thickness. Figure 5 and Figure 8 As shown, when the water supply pipe 1 and the splicing pipe 11 move downward under the action of gravity, the U-shaped side pressure plate 213 can horizontally squeeze the pressure bearing ring 14 and push the splicing pipe 11 to gradually extend out of the inner cavity of the end of the water supply pipe 1, so that the two splicing flanges 13 can approach each other and maintain a tight fit, thereby effectively improving the sealing effect between the two.

[0036] Furthermore, the anti-jump pressure plate 4 is rotatably installed on the side of the traveling frame 2 and located above the splicing pipe 11. The anti-jump pressure plate 4 is vertically set and its lower end presses down on the splicing pipe 11. The anti-jump pressure plate 4 abuts against the splicing pipe 11 from the upper side, which can prevent the splicing pipe 11 from jumping upward, thereby ensuring the stability of the splicing pipe 11 after splicing. In addition, since the downward pressure generated by the lower end of the anti-jump pressure plate 4 on the splicing pipe 11 is in the same direction as the weight of the splicing pipe 11, the U-shaped side pressure plate 213 can always squeeze the pressure ring 14, thereby ensuring that the two splicing flanges 13 always remain in a tight fit.

[0037] To prevent the water pipe 1 from shifting position, this application also includes a positioning collar 12 fixedly installed at the end of the water pipe 1, with the positioning collar 12 located between the first U-shaped pad 211 and the second U-shaped pad 212, such as... Figure 5As described above, after the water pipe 1 moves downward under the action of gravity, the positioning collar 12 can be precisely locked between the first U-shaped pad 211 and the second U-shaped pad 212, thereby achieving the positioning of the water pipe 1 and preventing the water pipe 1 from shifting in the horizontal direction. The splicing insertion hole 22 is set in the shape of a frustum, and the upper inner diameter of the splicing insertion hole 22 is larger than the lower inner diameter. The lower half of the inner wall of the splicing insertion hole 22 is provided with a relief groove 221 for the splicing flange 13 to move downward. The splicing flange 13 is first inserted into the inner cavity of the splicing insertion hole 22 from the upper part, and then slides downward into the inner cavity of the relief groove 221 under the action of gravity. At this time, the edge of the splicing insertion hole 22 is in contact with the surface of the splicing pipe 11, which can horizontally limit the splicing flange 13 and prevent the splicing flange 13 from moving horizontally, thereby ensuring the stability of the position of the splicing flange 13.

[0038] To suspend and position the water pipe 1, the traveling frame 2 of this application is in the shape of a vertical "X". A horizontally placed "X" shaped truss 3 is fixed between two adjacent traveling frames 2. The truss 3 is located above the water pipe 1. Multiple evenly distributed reinforcing beams 31 are fixed in the middle of the truss 3 to improve the overall strength of the truss 3. A U-shaped suspension frame 32 is fixedly installed on the lower side of the truss 3, and the water pipe 1 is placed from top to bottom on the inner bottom of the U-shaped suspension frame 32. The truss 3 uses the U-shaped suspension frame 32 to position the water pipe 1, thereby avoiding the water pipe 1 from bending and deforming due to excessive weight of the liquid inside the water pipe 1.

[0039] To further improve the stability of the water pipe 1, this application also includes a limiting ring 18 fixedly sleeved on the surface of the water pipe 1. The limiting ring 18 is set in groups of two and is located on both sides of the U-shaped suspension bracket 32. Multiple groups of limiting ring 18 and U-shaped suspension bracket 32 ​​are set and distributed at equal intervals along the length of the water pipe 1. The limiting ring 18 and U-shaped suspension bracket 32 ​​work together to ensure the stability of the water pipe 1 to the greatest extent. At the same time, the limiting ring 18 and U-shaped suspension bracket 32 ​​restrict each other in the horizontal direction, which can also ensure the stability of the position of the U-shaped suspension bracket 32 ​​itself.

[0040] To improve the strength of truss 3, the middle part of truss 3 in this application arches upward to form an arc shape, such as... Figure 9 The arc-shaped truss 3 has higher load-bearing strength and is not easily deformed, which can provide a stable suspension and positioning effect for the water supply pipe 1. Multiple evenly distributed water outlet pipes 16 are connected to the surface of the water supply pipe 1. The water outlet pipes 16 are in the shape of an inverted "J" and the lower end of the water outlet pipes 16 is equipped with a water outlet nozzle 17. The water outlet pipes 16 and the water outlet nozzles 17 are used for sprinkler irrigation or water mist spraying to farmland.

[0041] To facilitate the installation and adjustment of the anti-jump pressure plate 4, this application also includes a rotating shaft 24 movably passing through the middle of the traveling frame 2, located above the splicing insertion hole 22. The traveling frame 2 has a through hole 241 for the rotating shaft 24 to be inserted and maintain rotation. Two anti-jump pressure plates 4 are provided, located at opposite ends of the rotating shaft 24. A square frame 41 is fixedly mounted on the surface of the anti-jump pressure plate 4. A sliding block 42 is vertically slidably installed within the inner cavity of the square frame 41, and the sliding block 42 is fixedly connected to the end of the rotating shaft 24. Figure 6 As shown, the two anti-jump pressure plates 4 can rotate synchronously with the rotating shaft 24. By rotating the anti-jump pressure plates 4 to a horizontal position, it is easy to move the splicing pipe 11 and the water supply pipe 1 upwards and then disassemble them. After rotating the anti-jump pressure plates 4 to a vertical position and pressing against the splicing pipe 11, the splicing pipe 11 cannot move upwards, thus maintaining a stable position. In addition, the sliding block 42 can slide a certain distance in the inner cavity of the square frame 41, thereby changing the height of the anti-jump pressure plates 4 when they are placed vertically, ensuring that the lower end of the anti-jump pressure plates 4 can accurately press down on the splicing pipe 11. A flexible pad 46 is glued and fixed to the lower end of the anti-jump pressure plates 4, and the lower surface of the flexible pad 46 is concave inward to form an arc shape. The flexible pad 46 is used to protect the surface of the splicing pipe 11 and prevent the anti-jump pressure plates 4 from exerting too much downward pressure on the splicing pipe 11, which would damage the splicing pipe 11.

[0042] To adjust the downward pressure generated by the anti-jumping pressure plate 4 and the splicing pipe 11, this application further includes an adjusting plate 411 slidably installed in the inner cavity of the square frame 41, and an adjusting spring 412 fixedly installed between the adjusting plate 411 and the sliding block 42. An adjusting column 413 is threaded through the upper end of the square frame 41, and the lower end of the adjusting column 413 is rotatably connected to the middle of the adjusting plate 411. Figure 6 As shown, the adjusting spring 412 is a tension spring. When the anti-jump pressure plate 4 is set vertically, the anti-jump pressure plate 4 always has a downward tendency. By turning the adjusting column 413, the elastic force of the adjusting spring 412 can be changed, thereby changing the downward pressure generated by the anti-jump pressure plate 4 on the splicing pipe 11, thus ensuring the stability of the splicing pipe 11.

[0043] To rotate the anti-jump plate 4 to a horizontal position, this application further includes a hollow column 45 fixedly installed at the lower end of the outer side wall of the anti-jump plate 4, and an inlay groove 451 communicating with the hollow column 45 is opened at the lower end of the inner side wall of the anti-jump plate 4. A thrust spring 452 and a positioning bead 43 are installed inside the inlay groove 451. Positioning grooves 25 and guide grooves 26 corresponding to the positioning beads 43 are opened on both sides of the middle section of the traveling frame 2. The depth of the guide groove 26 is less than the depth of the positioning groove 25. Figure 6 and Figure 7As shown, when the anti-jump pressure plate 4 rotates, the positioning bead 43 can move along the inner cavity of the guiding groove 26. After the anti-jump pressure plate 4 rotates until the positioning bead 43 corresponds to the positioning groove 25, the anti-jump pressure plate 4 can maintain a stable position and will not rotate downward under the action of gravity.

[0044] To ensure the stability of the anti-jump pressure plate 4 when it is vertically placed, the present application also has a reinforcing rib plate 23 fixedly arranged in the middle of the walking frame 2, and the reinforcing rib plate 23 is in an "H" shape. A magnet sheet 231 is arranged in the middle of the reinforcing rib plate 23, and a handle frame 44 in a "C" shape is arranged on the outer side of the reinforcing rib plate 23. The two ends of the handle frame 44 are respectively rotatably sleeved on the outer sides of two hollow columns 45. The inner wall of the middle part of the handle frame 44 is in contact with and attracted to the surface of the magnet sheet 231. As Figure 7 and Figure 4 shown, when the anti-jump pressure plate 4 rotates downward to be vertically placed, the handle frame 44 can just buckle on the edge of the reinforcing rib plate 23, thereby preventing the lower end of the anti-jump pressure plate 4 from crossing over the splicing pipe 11. In addition, the middle part of the handle frame 44 and the magnet sheet 231 attract each other, which can ensure the stable position of the handle frame 44. Therefore, when the anti-jump pressure plate 4 is vertically placed, its own position is stable and it can generate a stable downward pressure on the splicing pipe 11.

[0045] The present invention also discloses an irrigation system, including the above-mentioned translational sprinkler irrigation machine. A cross plate 27 and walking wheels 28 are installed at the lower part of the walking frame 2. A driver 29 for controlling the rotation of the walking wheels 28 is installed on the cross plate 27. The walking frame 2 of the present device can move through the walking wheels 28, and multiple walking frames 2 move synchronously in the same direction. During the movement of the walking frame 2, in cooperation with an external water pump and a flexible pipeline, liquid can be conveyed into 1a, so as to be able to perform mobile sprinkler irrigation on farmland.
