[0031] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 9 , the present invention provides a technical solution:

[0033] Embodiment 1, a large-scale farmland translational sprinkler, comprises: a water delivery pipe 1, a traveling frame 2 and an anti-jump pressure plate 4.

[0034] Specifically, a splicing tube 11 is movably inserted at both ends of the water pipe 1, and an annular gasket 15 is provided at the fitting connection between the splicing tube 11 and the water pipe 1 to improve the plug-in sealing performance of the two. The splicing tube 11 can be horizontally displaced for a certain distance along the length direction of the water pipe 1. A splicing flange 13 and a pressure-bearing collar 14 are fixedly provided at one end and the middle of the splicing tube 11, respectively. The edge of the splicing flange 13 has holes. When the two splicing flanges 13 are close to each other and fit together, they can be initially fixed and connected by bolts, and a sealing ring is also provided on the surface of the splicing flange 13 to ensure the sealing performance between the two splicing flanges 13 to prevent liquid leakage;

[0035] Secondly, the walking frame 2 is located outside the end of the water pipe 1, and U-shaped sleeves 21 are fixedly installed on both sides of the walking frame 2. A splicing socket 22 corresponding to the inner cavity of the U-shaped sleeve 21 is opened through the middle of the walking frame 2. The splicing socket 22 is set so that the splicing flanges 13 on both sides of the walking frame 2 can be inserted into the inner cavity of the splicing socket 22 for splicing and fixing. A U-shaped pad 1 211 and a U-shaped pad 2 212 are fixedly set on the inner wall of the U-shaped sleeve 21, and the end of the water pipe 1 and the splicing pipe 11 are respectively placed on the U-shaped pad 1 211 and the inner side of the U-shaped pad 212, the U-shaped pad 1 211 is used to support the end of the water pipe 1, and the U-shaped pad 212 supports the splicing pipe 11 to ensure that the water pipe 1 and the splicing pipe 11 remain in line and will not bend to cause liquid leakage. A U-shaped side pressure plate 213 is fixedly arranged on the side of the U-shaped pad 212, and the U-shaped side pressure plate 213 horizontally squeezes the pressure ring 14. The side of the U-shaped side pressure plate 213 is inclined, and the upper thickness is less than the lower thickness. Figure 5 and Figure 8 As shown, when the water 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 collar 14 and push the splicing pipe 11 to gradually extend out of the inner cavity at the end of the water pipe 1, so that the two splicing flanges 13 can approach each other and keep a close fit, thereby effectively improving the sealing effect between the two;

[0036] Furthermore, the anti-jumping pressure plate 4 is rotatably installed on the side of the walking frame 2 and is located above the splicing tube 11. The anti-jumping pressure plate 4 is vertically arranged, and the lower end presses the splicing tube 11 downward. The anti-jumping pressure plate 4 supports the splicing tube 11 from the upper side, which can prevent the splicing tube 11 from jumping upward, thereby ensuring the stability of the splicing tube 11 of the device after splicing. In addition, because the downward pressure generated by the lower end of the anti-jumping pressure plate 4 on the splicing tube 11 is consistent with the direction of gravity of the splicing tube 11 itself, the U-shaped side pressure plate 213 can always squeeze the pressure-bearing ring 14, thereby ensuring that the two splicing flanges 13 always remain in a tightly fitted state.

[0037] In order to prevent the water pipe 1 from being offset, the present application also has a positioning collar 12 fixedly provided at the end of the water pipe 1, and the positioning collar 12 is located between the U-shaped pad 1 211 and the U-shaped pad 2 212. Figure 5As described, after the water pipe 1 moves downward under the action of gravity, the positioning ring 12 can be stuck between the U-shaped pad 1 211 and the U-shaped pad 212, so as to realize the positioning of the water pipe 1 and avoid the water pipe 1 from being offset in the horizontal direction. The splicing socket 22 is set to be a truncated cone, and the upper inner diameter of the splicing socket 22 is larger than the lower inner diameter. The lower inner wall of the splicing socket 22 is provided with an avoidance groove 221 for the splicing flange 13 to move downward. The splicing flange 13 is first inserted into the inner cavity of the splicing socket 22 from the upper part of the splicing socket 22, and then slides downward into the inner cavity of the avoidance groove 221 under the action of gravity. At this time, the edge of the splicing socket 22 is in contact with the surface of the splicing tube 11, which can limit the splicing flange 13 horizontally to avoid horizontal movement of the splicing flange 13, thereby ensuring the stability of the position of the splicing flange 13.

[0038] In order to suspend and position the water pipe 1, the traveling frame 2 of the present application is in a vertical "X" shape, and 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, and a plurality of evenly distributed reinforcing beams 31 are fixedly arranged 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 is used to position the water pipe 1 with the help of the U-shaped suspension frame 32, so as to avoid bending and deformation of the water pipe 1 due to excessive weight of the liquid inside the water pipe 1.

[0039] In order to further improve the position stability of the water pipe 1, the present application also has a limiting ring 18 fixedly sleeved on the surface of the water pipe 1. The limiting rings 18 are arranged in a group of two and are respectively located on both sides of the U-shaped suspension bracket 32. Both the limiting rings 18 and the U-shaped suspension bracket 32 ​​are arranged in multiple groups and are distributed at equal intervals along the length direction of the water pipe 1. The limiting rings 18 and the U-shaped suspension bracket 32 ​​cooperate to ensure the stability of the position of the water pipe 1 to the greatest extent. At the same time, the limiting rings 18 and the U-shaped suspension bracket 32 ​​restrict each other in the horizontal direction, and can also ensure the stability of the position of the U-shaped suspension bracket 32 ​​itself.

[0040] In order to improve the strength of the truss 3, the middle part of the truss 3 of the present application is arched upward to form an arc shape, such as Fig. 9 The arc-shaped truss 3 has a higher bearing strength and is not easily deformed, so it can provide a stable suspension and positioning effect for the water pipe 1. A plurality of evenly distributed water outlet pipes 16 are connected to the surface of the water pipe 1. The water outlet pipe 16 is in an inverted "J" shape, and a water outlet nozzle 17 is installed at the lower end of the water outlet pipe 16. The water outlet pipe 16 and the water outlet nozzle 17 are arranged for irrigating or spraying water mist on farmland.

[0041] In order to install and adjust the anti-jump pressure plate 4, the present application also has a rotating shaft 24 located above the splicing socket 22 and movably penetrated in the middle of the walking frame 2. A through hole 241 is provided on the walking frame 2 for the rotating shaft 24 to be plugged in and keep rotating. Two anti-jump pressure plates 4 are provided and are respectively located at both ends of the rotating shaft 24. A square frame 41 is fixedly provided on the surface of the anti-jump pressure plate 4. A sliding block 42 is vertically slidably installed in the inner cavity of the square frame 41, and the sliding block 42 is fixedly connected to the end of the rotating shaft 24, such as Figure 6 As shown, the two anti-jumping pressure plates 4 can keep rotating synchronously with the rotating shaft 24. By rotating the anti-jumping pressure plate 4 to a horizontal position, it is convenient to move the splicing pipe 11 and the water pipe 1 upward and then realize disassembly. After the anti-jumping pressure plate 4 is rotated to a vertical position and against the splicing pipe 11, the splicing pipe 11 cannot move upward, thereby 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-jumping pressure plate 4 when it is placed vertically, ensuring that the lower end of the anti-jumping pressure plate 4 can accurately press down on the splicing pipe 11. A flexible pad 46 is bonded and fixed to the lower end of the anti-jumping pressure plate 4, and the lower surface of the flexible pad 46 is concave inward to form an arc shape. The flexible pad 46 is provided to protect the surface of the splicing pipe 11 to prevent the anti-jumping pressure plate 4 from exerting excessive downward pressure on the splicing pipe 11 and causing damage to the splicing pipe 11.

[0042] In order to adjust the downward pressure generated by the anti-jump pressure plate 4 on the splicing pipe 11, the present application also has an adjustment plate 411 slidably installed in the inner cavity of the square frame 41, and an adjustment spring 412 is fixedly arranged between the adjustment plate 411 and the sliding block 42, and an adjustment column 413 is arranged on the upper end of the square frame 41 through a thread, and the lower end of the adjustment column 413 is rotatably connected to the middle part of the adjustment plate 411, such as Figure 6 As shown, the adjustment spring 412 is a tension spring. When the anti-jumping pressure plate 4 is set vertically, the anti-jumping pressure plate 4 always has a tendency to move downward. By twisting the adjustment column 413, the elastic force of the adjustment spring 412 can be changed, thereby changing the downward pressure generated by the anti-jumping pressure plate 4 on the splicing tube 11, thereby ensuring the stability of the splicing tube 11.

[0043] In order to rotate the anti-jumping pressure plate 4 to a horizontal position, the present application also has a hollow column 45 fixedly arranged at the lower end of the outer wall of the anti-jumping pressure plate 4, an inlay groove 451 connected to the hollow column 45 is provided at the lower end of the inner wall of the anti-jumping pressure plate 4, a thrust spring 452 and a positioning bead 43 are provided in the inner cavity of the inlay groove 451, and a positioning groove 25 and a guide groove 26 corresponding to the positioning bead 43 are provided on both sides of the middle part of the walking frame 2, and 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 attached to 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 traveling sprinkler, and a cross plate 27 and traveling wheels 28 are installed at the lower part of the walking frame 2. A driver 29 for controlling the rotation of the traveling wheels 28 is installed on the cross plate 27. The walking frame 2 of the present device can move through the traveling 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.

[0046] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
