Description

Technical Field

[0001] This utility model relates to the field of water-saving irrigation technology, and more specifically, to a mobile water-saving irrigation rack for farmland. Background Technology

[0002] Agricultural irrigation equipment is used for irrigation and drainage of farmland and other fields. It can regulate regional water conditions, improve farmland moisture, and prevent drought, flooding, salinity, and alkali disasters, thereby promoting stable and high agricultural yields. Irrigation methods can generally be divided into traditional surface irrigation, ordinary sprinkler irrigation, and micro-irrigation. In order to improve water-saving efficiency, existing farmland irrigation equipment mostly adopts a multi-pipe structure, laying pipes at corresponding locations in the field to form a pipe network for irrigation of different locations.

[0003] However, in actual use, there are still some shortcomings. For example, although the existing mobile water-saving irrigation racks for farmland can achieve irrigation, in actual use, there are many problems because the nozzles cannot swing left and right. During irrigation, the water distribution often shows a situation of "more in the center and less at the edge". Adjacent work areas are prone to missed spraying or double spraying. This not only causes unnecessary waste of water resources, but also affects the uniformity of crop growth due to uneven water supply, which has an adverse effect on the yield and quality of subsequent crops. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a mobile water-saving irrigation frame for farmland. The rotation of wheels drives a disc, causing the protrusions on the disc to strike a long rod. This long rod then drives the connecting rod, which in turn causes the nozzle to sway left and right on the support frame, thereby ensuring uniform irrigation of the farmland and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile water-saving irrigation frame for farmland, including a support frame and wheels connected to the support frame. The support frame includes a support frame one and a support frame two. A shaft is provided on the support frame one, and bushings are fitted at both ends of the shaft. The wheel hub is mounted on the bushings.

[0006] Multiple nozzles are rotatably mounted on the second bracket, and the ends of the nozzles are rotatably connected to rods.

[0007] The bracket is rotatably mounted with a long rod, and the top of the long rod is rotatably assembled with the rod member.

[0008] The bushing is fitted with a disc, and the disc has multiple protrusions on its side. The disc can rotate synchronously with the bushing. At the same time, the protrusions on the disc touch the bottom of the long rod, and the rotation of the long rod drives the rod and the nozzle to rotate.

[0009] In a preferred embodiment, the second bracket is mounted on the shaft via a connecting rod, and multiple nozzles are equidistantly arranged on the second bracket, with water receiving pipes on the pipe walls of the nozzles;

[0010] An assembly rod is installed on the bracket.

[0011] In a preferred embodiment, the bottom of the nozzle is rotatably assembled with the bracket via a shaft, and the rod is located at the tail of the nozzle and connected via a rotating shaft, that is, multiple nozzles are rotatably assembled with the rod.

[0012] A long rod is mounted on the second bracket via an axis. The long rod is located at both ends of the rod, and the top of the long rod is rotatably connected to the rod.

[0013] In a preferred embodiment, the protrusion is a hemisphere, and multiple protrusions are arranged at equal angles on the side of the disk.

[0014] In a preferred embodiment, a limiting hole one and a limiting hole two are provided on the hub of the wheel along the axial direction. The openings of the limiting holes are connected to each other, and the depth of the limiting hole one is less than the depth of the limiting hole two.

[0015] A limiting rod is set on the other side of the disc, allowing the disc to move and rotate axially on the bushing.

[0016] In a preferred embodiment, a spring is also fitted onto the bushing, and a retaining ring with a diameter larger than that of the spring is integrally provided at the end of the bushing;

[0017] A notch is cut on the bottom side of the rod, and the edge of the notch is rounded.

[0018] In a preferred embodiment, the second bracket is further provided with a hook end, and a tension spring is hooked between the hook end and the top of the rod.

[0019] The technical effects and advantages of this utility model are as follows: By rotating the wheel to drive the disc, the protruding structure on the disc collides with the long rod. After the impact, the long rod will link with the subsequent rods, thereby driving the nozzle to swing left and right on the bracket, ultimately making the water distribution in the irrigation area more uniform, thus solving the problems of uneven spraying, water waste and inconsistent crop growth of existing equipment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] As attached Figure 1 With appendix Figure 5 The mobile water-saving irrigation frame for farmland shown includes a support frame 2, with shafts 7 at both ends of the support frame 2, and bushings 18 are fitted at both ends of the shafts 7. The bushings 18 are rotatably assembled at both ends of the shafts 7. The wheel hubs 19 of the wheels 5 are fitted on the bushings 18 and rotate synchronously with the bushings 18.

[0028] A second support 6 is also set on the shaft 7 via a connecting rod, and multiple nozzles 3 are equidistantly set on the second support 6. The pipe wall of the nozzle 3 is equipped with a water receiving pipe 4. During operation, the water receiving pipe 4 is connected to an external water source, and the nozzle 3 sprays water for irrigation. After completing the operation in a certain area, it can be moved manually to the next position to achieve flexible fixed-point irrigation. Through flexible movement, the equipment can also be connected to external traction equipment, such as tractors, by setting an assembly rod 1 on the first support 2. It is suitable for emergency or supplementary irrigation of small-scale farmland such as mountains and slopes.

[0029] In the above solution, in order to solve the problem of the traditional fixed-direction spraying method of the nozzle 3, this technical solution increases the spraying coverage area by allowing the nozzle 3 to swing left and right.

[0030] The bottom of the nozzle 3 is rotatably assembled with the bracket 2 6 via a shaft. A rod 20 is connected to the tail of the nozzle 3 via a rotating shaft. That is, multiple nozzles 3 are rotatably assembled with the rod 20. A long rod 10 is also set on the bracket 2 6 via a shaft. The long rod 10 is located at both ends of the rod 20, and the top of the long rod 10 is rotatably connected to the rod 20. The drive at the bottom of the long rod 10 causes the rod 20 to drive multiple nozzles 3 to swing.

[0031] A disc 11 is fitted onto the bushing 18. Multiple protrusions 21 are provided at equal angles on the side of the disc 11. The protrusions 21 are hemispherical. The disc 11 can rotate with the bushing 18. The protrusions 21 touch the bottom of the rod 20, causing the rod 20 to rotate.

[0032] A limiting hole 13 and a limiting hole 14 are made axially on the hub 19 of the wheel 5. The openings of the limiting holes are connected to each other. At the same time, the depth of the limiting hole 13 is less than the depth of the limiting hole 14. A limiting rod 15 is set on the other side of the disc 11. The disc 11 can move and rotate axially on the bushing 18. When the rod 20 needs to swing, the disc 11 is moved axially and the disc 11 is rotated to remove the limiting rod 15 from the limiting hole 14 and insert it into the limiting hole 13, so that the disc 11 rotates synchronously with the bushing 18 and the hub 19.

[0033] A spring 12 is also fitted on the bushing 18. A retaining ring 8 with a diameter larger than that of the spring 12 is integrally provided at the end of the bushing 18 to prevent the spring 12 from falling off. After the disc 11 is moved, the disc 11 will squeeze the spring 12. Through the action of the spring 12, the limiting rod 15 can be stably inserted into the limiting hole 13 after the disc 11 is moved.

[0034] The irrigation frame can also be connected to an external traction device via the mounting rod 1 during use. When the irrigation frame moves, the rotation of its wheels 5 can synchronously drive multiple nozzles 3 to swing back and forth, increasing the coverage area of ​​the spray.

[0035] A notch 9 is made on the bottom side of the rod 20. The edge of the notch 9 is rounded. This structure mainly serves to ensure that the disc 11 can rotate smoothly and to prevent the bottom of the rod 20 from being stuck by the protrusion 21, which would prevent the wheel 5 from rotating.

[0036] A hanging end 17 is also provided on the bracket 26. A tension spring 16 is hung between the hanging end 17 and the top of the rod 20. When there is no external force at the bottom of the rod 20, the tension of the tension spring 16 can ensure that the nozzle 3 is perpendicular to the bracket 26, that is, the nozzle 3 can spray vertically forward.

[0037] This irrigation rack features both directional spraying and left-right swinging spraying modes, which can be selected by moving the disc 11 according to the crop planting conditions, making it easy to operate.

[0038] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
