Description

Technical Field

[0001] This utility model relates to the field of sprinkler irrigation technology, specifically to a rotary sprinkler irrigation machine for water conservancy irrigation. Background Technology

[0002] With the continuous growth of the global population and the uneven distribution of water resources due to climate change, agricultural irrigation has become an important means to increase crop yields and ensure food security. In agricultural production, irrigation is not only related to the growth of crops, but also directly affects the effective use of water resources.

[0003] Traditional irrigation methods, such as flood irrigation, rely on the natural flow of water to infiltrate farmland. This not only results in significant water waste with a utilization rate of only 40%–50%, but also in slow irrigation speeds, failing to quickly meet the water needs of crops. With technological advancements, sprinkler irrigation has emerged. Sprinkler irrigation uses pumps to pressurize water, transforming it into a mist or droplets that are then evenly sprayed onto farmland, simulating the natural rainfall process and overcoming terrain limitations. However, it still has shortcomings in practical use. For example, some fixed-nozzle sprinkler systems cannot rotate their nozzles. For large areas of farmland, a large number of nozzles and complex piping are required to achieve comprehensive coverage, undoubtedly increasing equipment costs and installation difficulty. Furthermore, existing sprinkler systems are not convenient for adjusting the spray volume according to actual needs, which not only exacerbates water waste but also leads to uneven crop growth, soil degradation, ecological problems, and increased management costs—a series of negative consequences. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a rotary sprinkler irrigation machine for water conservancy irrigation, which can effectively solve the problems of the existing technology where the sprinkler head cannot rotate and it is not convenient to adjust the spraying water volume according to actual needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The water volume regulating component includes a rotating rod that is slidably connected through the side wall of the rotating pipe. A water volume regulating plate is fixedly connected to one end of the rotating rod located inside the rotating pipe. The pipe body of the rotating pipe is provided with a second driving component for driving the rotating rod to rotate.

[0008] According to the above-mentioned rotary sprinkler irrigation machine for water conservancy, the first drive assembly includes an equipment box fixedly connected to the upper end of the base plate, a drive motor fixedly installed inside the equipment box, and a drive gear meshing with the driven gear fixedly connected to the output end of the drive motor.

[0009] According to the above-mentioned rotary sprinkler irrigation machine for water conservancy, the upper end of the base pipe is provided with a limiting groove, and the lower end of the rotary pipe is fixedly connected with a limiting ring that is connected to the limiting groove for limiting rotation.

[0010] According to the above-mentioned rotary sprinkler irrigation machine for water conservancy, the limiting groove is narrow at the top and wide at the bottom, and the shape of the limiting ring is adapted to the limiting groove.

[0011] According to the above-mentioned rotary sprinkler irrigation machine for water conservancy, a sealing ring is fixedly bonded to the lower end of the limiting ring, and the sealing ring is located between the limiting ring and the limiting groove.

[0012] According to the above-mentioned rotary sprinkler irrigation machine for water conservancy, the second drive assembly includes a mounting box fixedly connected to the body of the rotating pipe. The inner top wall of the mounting box is rotatably connected to a drive bevel gear, which meshes with a driven bevel gear. A rotary motor for driving the drive bevel gear to rotate is fixedly installed at the upper end of the mounting box. The driven bevel gear is coaxially fixedly connected to the water volume regulating plate.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0014] This invention uses a drive motor and gear transmission to rotate the pipe and drive the nozzle to rotate 360 ​​degrees at a uniform speed. A single device can cover a large area of ​​farmland, reducing the number of nozzles and the cost of laying pipes, and reducing the difficulty of equipment installation.

[0015] This invention uses a rotary motor and bevel gear set to drive a water volume regulating plate, achieving stepless adjustment of the spray volume from 0% to 100%. It can be adjusted in real time according to the crop growth cycle (such as the seedling stage requiring less water) and weather conditions (such as reducing spraying during the rainy season), avoiding water waste, soil degradation and uneven crop growth caused by excessive irrigation.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example: Refer to Figures 1 to 3 A rotary sprinkler irrigation machine for water conservancy includes a base plate 1. A base pipe 2 is fixedly connected to the upper end of the base plate 1. A connecting pipe 3 is connected to the body of the base pipe 2. The base plate 1 serves as the support structure for the whole machine and is fixed to the ground of the irrigation area by anchor bolts. The base pipe 2 is vertically fixed to the upper end of the base plate 1, and its lower side is connected to an external water source (such as a water supply network or water pump) through the connecting pipe 3 to form a water inlet.

[0024] The upper end of the base pipe 2 is rotatably connected to a rotating pipe 4. A limiting groove 21 is opened at the upper end of the base pipe 2. A limiting ring 41 is fixedly connected to the lower end of the rotating pipe 4 and is rotatably connected to the limiting groove 21. The limiting groove 21 is narrow at the top and wide at the bottom, and the shape of the limiting ring 41 is adapted to the limiting groove 21. The limiting ring 41 fixed at the lower end of the rotating pipe 4 is embedded in the limiting groove 21. The two cooperate under special circumstances to achieve limiting rotation, which not only ensures that the rotating pipe 4 can rotate freely around the axis of the base pipe 2, but also prevents it from axially disengaging through the geometry of the limiting groove 21.

[0025] A sealing ring is fixedly bonded to the lower end of the limiting ring 41, and the sealing ring is located between the limiting ring 41 and the limiting groove 21 to form a dynamic seal and prevent water from leaking from the connection between the base pipe 2 and the rotating pipe 4.

[0026] A driven gear 7 is fixedly sleeved on the body of the rotating pipe 4. A first drive assembly for driving the driven gear 7 to rotate is provided at the upper end of the base plate 1. Specifically, the first drive assembly includes an equipment box 5 fixedly connected to the upper end of the base plate 1. A drive motor is fixedly installed inside the equipment box 5. The output end of the drive motor is fixedly connected to a drive gear 6 that meshes with the driven gear 7. When the drive motor starts, it drives the rotating pipe 4 to rotate at a constant speed around the axis of the base pipe 2 through gear transmission, so as to achieve 360-degree coverage spraying of the nozzle (not shown in the figure, usually installed at the top of the rotating pipe 4).

[0027] A water volume regulating component is installed inside the rotating pipe 4. Specifically, the water volume regulating component includes a rotating rod 8 that is slidably connected to the side wall of the rotating pipe 4. A water volume regulating plate 9 is fixedly connected to one end of the rotating rod 8 inside the rotating pipe 4. The rotation angle of the water volume regulating plate 9 directly affects the water flow cross-sectional area. When the water volume regulating plate 9 is perpendicular to the water flow direction, the water flow cross-sectional area is the smallest and the water volume is the smallest. When the water volume regulating plate 9 is parallel to the water flow direction, the water flow cross-sectional area is the largest and the water volume is the largest. By stopping the water volume regulating plate 9 at any angle between 0 degrees and 90 degrees, the spraying water volume can be infinitely adjusted.

[0028] The rotating pipe 4 is equipped with a second drive assembly for driving the rotating rod 8 to rotate. Specifically, the second drive assembly includes a mounting box 10 fixedly connected to the pipe body of the rotating pipe 4. An active bevel gear 11 is rotatably connected to the inner top wall of the mounting box 10. The active bevel gear 11 meshes with a driven bevel gear 13. A rotary motor 12 for driving the active bevel gear 11 to rotate is fixedly installed at the upper end of the mounting box 10. The driven bevel gear 13 is coaxially fixedly connected to the water flow regulating plate 9. Through the vertical transmission of the bevel gear set, the influence of water pressure on the output end of the rotary motor is reduced. The rotary motor 12 drives the active bevel gear 11 to rotate, and transmits power to the rotating rod 8 through the meshing driven bevel gear 13. Since the driven bevel gear 13 is coaxially fixed with the rotating rod 8, the rotation of the active bevel gear can synchronously drive the water flow regulating plate 9 to rotate, realizing the automated control of water flow regulation.

[0029] The working principle of this utility model is as follows:

[0030] External water sources (such as water flow pressurized by a water pump) enter the base pipe 2 through the connecting pipe 3, flow into the interior of the rotating pipe 4 through the connection between the base pipe and the rotating pipe 4, and finally spray out from the nozzle at the top of the rotating pipe 4. The drive motor in the equipment box 5 drives the active gear 6 to rotate, and through the meshing driven gear 7, drives the rotating pipe 4 to rotate at a constant speed around the axis of the base pipe 2 to achieve rotating irrigation.

[0031] When adjusting the water volume, the rotary motor 12 drives the driving bevel gear 11 to rotate, which in turn drives the rotating rod 8 to rotate through the meshing driven bevel gear 13, thereby controlling the angle of the water volume regulating plate 9.

[0032] When the regulating plate is parallel to the water flow direction, the water flow channel is fully open, the cross-sectional area of ​​water passage is at its maximum, and the water spray volume reaches its peak.

[0033] When the regulating plate is perpendicular to the water flow direction, the water flow channel is completely blocked and the water spray volume is zero.

[0034] When the regulating plate stops at any angle between 0 and 90 degrees, the water spray volume can be infinitely adjusted by changing the cross-sectional area of ​​the water passage.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
