Description

Technical Field

[0002] Agricultural planting is a social production sector that utilizes the functions of plants to obtain food, non-staple food, feed and industrial raw materials through artificial cultivation. In agricultural planting, plants need to be watered, fertilized and sprayed with pesticides. With the development of science and technology, there are a variety of sprinkler irrigation devices on the market.

[0003] Specifically, the common water-saving sprinkler irrigation devices for agricultural planting on the market currently have the following shortcomings: Although traditional sprinkler irrigation devices can achieve large-scale irrigation, they have obvious shortcomings in water conservation. Many sprinkler irrigation devices lack flexibility in water flow guidance and flow control. In actual agricultural production, different crops have specific requirements for irrigation areas and water volumes at different growth stages. For example, crops in the seedling stage may only need precise irrigation of a small area near their roots, but existing sprinkler irrigation devices often find it difficult to accurately control the direction and flow of water flow, which can easily cause water to be sprayed on areas that do not require irrigation, resulting in a waste of water resources. Existing sprinkler irrigation devices cannot reasonably adjust the amount of irrigation water according to the specific conditions of soil moisture. They may over-irrigate areas where soil moisture is already high, and under-irrigate areas that are relatively dry. This not only wastes water resources, but may also affect the growth quality of crops. Summary of the invention

[0017] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0018] A water-saving sprinkler irrigation device for agricultural planting according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0019] like Figures 1 to 11 As shown, an embodiment of the present invention provides a water-saving sprinkler device for agricultural planting, a liquid drainage component 1, including a liquid reservation frame 2 and a frame baffle 4, the shape of the liquid reservation frame 2 is set to be cylindrical, the shape of the frame baffle 4 is set to be semi-arc, and the frame baffle 4 is provided with two groups, and the two groups of frame baffles 4 are arranged on the outside of the liquid reservation frame 2; an annular guard plate 12 is provided on the outside of the liquid reservation frame 2, and an electric telescopic device 3 is provided on the inner wall of the annular guard plate 12, and the frame baffle 4 is arranged at the working end of the electric telescopic device 3, and a matching limit frame 13 is provided on the bottom surface of the annular guard plate 12; a driving motor 8 is provided above the liquid reservation frame 2, and a rotating shaft 9 is provided at the output end of the driving motor 8, and one end of the rotating shaft 9 is arranged on the top surface of the liquid reservation frame 2, and an auxiliary rod 10 is provided on the bottom surface of the liquid reservation frame 2, and a bearing seat 11 is provided on the bottom surface of the auxiliary rod 10.

[0020] In a specific application of the embodiment of the present invention, the electric telescopic device 3 is started through the control panel 27. Since the frame baffle 4 is arranged at the working end of the electric telescopic device 3, when the electric telescopic device 3 is extended or contracted, the semi-arc frame baffle 4 will move accordingly on the outside of the liquid reserved frame 2. In the process of liquid flowing from the water source into the liquid reserved frame 2, the position change of the frame baffle 4 will change the flow path and flow rate of the liquid in the reserved frame. For example, when the electric telescopic device 3 is extended to bring the two groups of frame baffles 4 closer together, the liquid can be gathered and guided so that the liquid flows out of the liquid reserved frame 2 in a specific direction; conversely, when the frame baffle 4 is moved away, the outflow range of the liquid will increase, and the flow rate may also change accordingly.

[0021] The limit frame 13 on the bottom surface of the annular guard plate limits the excessive displacement of the electric telescopic device 3 and the frame baffle 4, ensuring that they operate within the normal working range and ensuring the accuracy and stability of liquid drainage. After the drive motor 8 is started, the rotating shaft 9 at its output end begins to rotate, and one end of the rotating shaft 9 is connected to the top surface of the liquid reservation frame 2. During the rotation process, the liquid inside the liquid reservation frame 2 is stirred.

[0022] In a possible implementation, a bottom plate 7 is provided inside the liquid reservation frame 2 , impurity adsorption rods 5 are provided on the top surface of the bottom plate 7 , six groups of impurity adsorption rods 5 are provided, and filtering holes 6 are opened on the outer wall of the liquid reservation frame 2 .

[0023] In specific applications of the embodiments of the present invention, since irrigation water may come from a variety of water sources, such as ponds, rivers, etc., the water often contains silt, algae or other tiny pollutants, and the impurity adsorption rod 5 can perform a relatively comprehensive impurity adsorption on the irrigation water entering therein. The impurity adsorption rod 5 can target impurities of different sizes and types in the water, such as suspended tiny particles, possible organic impurities, etc. For example, if the surface of the adsorption rod has tiny pores or has electrostatic adsorption properties, then the charged impurity particles in the water or tiny substances that can be trapped by the pores will be adsorbed.

[0024] The water that has been initially filtered by the impurity adsorption rod needs to pass through the filter hole 6 when flowing to the outside of the liquid reserved frame 2. The filter hole 6 further filters the water. On the basis of the initial filtration by the impurity adsorption rod, slightly larger particles of impurities can be intercepted, thereby preventing some larger impurities from entering the subsequent pipes or nozzles of the sprinkler irrigation system.

[0025] When the nozzles of the sprinkler are not blocked by impurities, water can be evenly sprayed in a predetermined manner, avoiding local over-irrigation or insufficient irrigation of other parts due to nozzle blockage. Uniform irrigation can ensure that crops fully absorb water and reduce the waste of water resources. At the same time, reducing nozzle blockage also reduces the frequency of maintenance and avoids waste of water resources such as leakage during maintenance.

[0026] In a possible embodiment, a working cylinder 26 and a liquid drainage assembly 1 are arranged inside the working cylinder 26, and a liquid pump 20 is also arranged inside the working cylinder 26. A connecting pipe 21 is provided at the working end of the liquid pump 20, and the other end of the connecting pipe 21 is arranged inside the annular guard plate 12. A delivery pipe 15 is provided at the output end of the liquid pump 20, and the liquid flow limiting assembly 14 is arranged inside the delivery pipe 15.

[0027] In a specific application of the embodiment of the present invention, the connecting pipe 21 at the working end of the liquid pump 20 penetrates into the annular guard plate 12. When the liquid pump 20 is started, the connecting pipe 21 generates negative pressure in the working cylinder 26, and the irrigation liquid in the working cylinder 26 is sucked into the liquid pump 20 under the action of the pressure difference. Then, the liquid pump 20 delivers the extracted liquid to the outside through the delivery pipe 15 at the output end.

[0028] The liquid flow limiting component 14 is located inside the delivery pipe 15, and controls the flow rate of the liquid by changing the flow cross-sectional area in the delivery pipe 15 or generating a certain resistance to the flow of the liquid. For example, the liquid flow limiting component 14 is equivalent to a throttle valve, and by adjusting the opening of the valve, the size of the gap through which the liquid passes can be changed, thereby controlling the amount of liquid passing through the delivery pipe 15 per unit time.

[0029] The liquid drainage assembly 1 is located inside the working cylinder 26 and guides the liquid in the working cylinder 26 to flow toward the working end of the liquid pump 20, ensuring that the liquid can be efficiently extracted by the liquid pump 20 and avoiding liquid retention or uneven flow in the working cylinder 26.

[0030] In a possible embodiment, the liquid flow limiting assembly 14 includes a flow limiting plate 17 and a traction rope 18, one end of the traction rope 18 is arranged on the top surface of the flow limiting plate 17, and the other end of the traction rope 18 is provided with a fixing plate 19, and a groove is provided in the middle of the fixing plate 19, and the size of the groove is adapted to the size of the flow limiting plate 17; a filter plate 16 is provided inside the delivery pipe 15, and the filter plate 16 is provided below the flow limiting plate 17, and a liquid nozzle 22 is provided at the other end of the delivery pipe 15.

[0031] In a specific application of the embodiment of the present invention, the liquid pump 20 delivers the liquid to the liquid nozzle 22 through the delivery pipe 15. When the sprinkler flow rate needs to be adjusted, the flow limiting plate 17 can be pulled upward (assuming that the opening of the flow limiting plate 17 can be increased when the traction rope 18 moves upward). In this way, the opening of the flow limiting plate 17 in the delivery pipe 15 is increased, and more water can pass through; conversely, if the flow rate needs to be reduced, the flow limiting plate 17 is pushed downward to reduce the opening, thereby reducing the amount of water passing through.

[0032] In agricultural irrigation, the water source may contain impurities such as silt, weed debris, etc. The filter plate 16 is located below the flow limiting plate 17. The filter plate 16 can intercept these impurities and prevent them from continuing to flow with the water flow, thereby avoiding clogging the liquid nozzle 22, helping to maintain the normal working state of the nozzle 22 and ensuring the uniformity and effectiveness of the sprinkler irrigation. For example, if impurities enter the nozzle 22, the internal structure of the nozzle, such as the spray hole, etc., may be damaged, and the filter plate 16 can reduce this risk, extend the service life of the sprinkler irrigation device, and reduce maintenance costs.

[0033] The liquid nozzle 22 evenly sprays the water after the flow rate is controlled by the flow limiting plate 17 and filtered by the filter plate 16 into the farmland. The uniform sprinkler irrigation helps the crops to absorb water evenly and ensure the consistency of crop growth. For example, for crops with a high planting density, the uniform sprinkler irrigation can make each crop get the right amount of water to avoid local waterlogging or drought.

[0034] In a possible embodiment, a support rod 23 is provided on the outer side of the liquid nozzle 22, and a liquid holding frame 24 is provided at the other end of the support rod 23. The liquid holding frame 24 is arranged below the liquid nozzle 22, and L-shaped infusion tubes 25 are respectively provided on both sides of the liquid holding frame 24. The other ends of the two groups of L-shaped infusion tubes 25 are respectively arranged on the outer sides of the liquid pump 20.

[0035] In a specific application of the embodiment of the present invention, first, the liquid pump 20 transports the liquid to the liquid nozzle 22 through a pipeline, and the liquid nozzle 22 sprays the liquid to irrigate the crops. During the spraying process, part of the liquid cannot be completely absorbed by the crops due to various factors and drips into the liquid holding frame 24. The other ends of the two groups of L-shaped liquid infusion pipes 25 outside the liquid holding frame 24 are respectively connected to the outside of the liquid pump 20, and the collected liquid can be sent back to the liquid pump 20 through the L-shaped liquid infusion pipes 25, which can collect the liquid that is not effectively utilized within the spraying range of the nozzle to the greatest extent. The recycled liquid can be sprayed again after passing through the liquid pump 20, and the same amount of initial liquid can be used to achieve more irrigation operations, thereby improving the working efficiency and equipment utilization rate of the entire sprinkler irrigation device.

[0036] At the same time, the liquid holding frame 24 is below the nozzle, and can redistribute the liquid sprayed by the nozzle to a certain extent. For example, if the nozzle sprays unevenly locally, the liquid collected by the liquid holding frame 24 can make up for some of the uneven spraying after being re-transported and sprayed, making the irrigation more uniform within a certain range, which is beneficial to the growth of crops.

[0037] In a possible implementation, a control panel 27 is provided on the outer wall of the working cylinder 26 , and the control panel 27 is electrically controlled and connected to the electric telescopic device 3 , the driving motor 8 , and the liquid pump 20 through conductive wires.

[0038] In the specific application of the embodiment of the present invention, the electric telescopic device 3, the driving motor 8 and the liquid pump 20 used in the device are all mature existing technologies. The working principles of the electric telescopic device 3, the driving motor 8 and the liquid pump 20 are also well known to people in this technical field and will not be described in detail here.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0040] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
