Description

Technical Field

[0001] The invention belongs to the technical field of agricultural irrigation, and in particular relates to a water-saving sprinkler irrigation device for agricultural planting. Background Art

[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:

[0004] Although traditional sprinkler irrigation systems can achieve large-scale irrigation, they have obvious shortcomings in terms of water conservation. Many sprinkler irrigation systems 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 require precise irrigation of a small area near their roots, but existing sprinkler irrigation systems often find it difficult to accurately control the direction and flow of water flow, which can easily lead to water being sprayed into areas that do not require irrigation, resulting in a waste of water resources. Existing sprinkler irrigation systems 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 drier areas. This not only wastes water resources, but may also affect the growth quality of crops.

[0031] The following describes embodiments of the present invention in detail, 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 are not to be construed as limiting the present invention.

[0032] 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.

[0033] 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 there are two groups of frame baffles 4, which 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, the frame baffle 4 is provided at the working end of the electric telescopic device 3, and a corresponding limit frame 13 is provided on the bottom surface of the annular guard plate 12; a drive motor 8 is provided above the liquid reservation frame 2, and a rotating shaft 9 is provided at the output end of the drive motor 8, one end of the rotating shaft 9 is provided 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.

[0034] In a specific application of the embodiment of the present invention, the electric telescopic device 3 is activated through the control panel 27. Since the frame baffle 4 is provided at the working end of the electric telescopic device 3, when the electric telescopic device 3 is extended or retracted, the semi-arc-shaped frame baffle 4 will move accordingly on the outside of the liquid reservation frame 2. During the process of liquid flowing from the water source into the liquid reservation frame 2, the position change of the frame baffle 4 will change the flow path and flow rate of the liquid in the reservation frame. For example, when the electric telescopic device 3 is extended and the two sets of frame baffles 4 are brought closer together, the liquid can be gathered and guided so that the liquid flows out of the liquid reservation frame 2 in a specific direction; conversely, when the frame baffles 4 are moved away, the outflow range of the liquid will increase, and the flow rate may also change accordingly.

[0035] The limit frame 13 on the bottom surface of the annular guard plate limits excessive displacement of the electric expander 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. 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.

[0036] In a possible embodiment, 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 , and six groups of impurity adsorption rods 5 are provided. Filter holes 6 are opened on the outer wall of the liquid reservation frame 2 .

[0037] In specific applications of the embodiments of the present invention, since irrigation water may come from a variety of sources, such as ponds and rivers, and often contains silt, algae, or other small contaminants, the impurity adsorption rods 5 can perform relatively comprehensive impurity adsorption on the incoming irrigation water. The impurity adsorption rods 5 can target impurities of different sizes and types in the water, such as suspended microparticles and potential organic impurities. For example, if the adsorption rod surface has tiny pores or electrostatic adsorption properties, then charged impurity particles in the water or tiny substances that can be trapped by the pores will be adsorbed.

[0038] After the water has been initially filtered by the impurity adsorption rod, it 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, which can prevent some larger impurities from entering the subsequent pipes or nozzle parts of the sprinkler system.

[0039] When sprinkler nozzles are free of clogs, water is evenly distributed in a predetermined pattern, avoiding over-irrigation in some areas or under-irrigation in others due to nozzle blockage. This uniform irrigation ensures that crops receive sufficient water, minimizing water waste. Furthermore, reducing nozzle blockage reduces maintenance frequency, preventing water leaks and other potential water waste during repairs.

[0040] In one possible embodiment, the working cylinder 26 and the liquid drainage assembly 1 are arranged inside the working cylinder 26, and a liquid pump 20 is also provided inside the working cylinder 26. The working end of the liquid pump 20 is provided with a connecting pipe 21, and the other end of the connecting pipe 21 is provided inside the annular guard plate 12. The output end of the liquid pump 20 is provided with a delivery pipe 15, and the liquid flow limiting assembly 14 is provided inside the delivery pipe 15.

[0041] In practical applications of this embodiment of the present invention, the connecting pipe 21 at the working end of the liquid pump 20 extends deep into the annular guard plate 12. When the liquid pump 20 is activated, the connecting pipe 21 generates negative pressure within the working cylinder 26. The pressure differential causes the irrigation liquid within the working cylinder 26 to be drawn into the liquid pump 20. The liquid pump 20 then delivers the extracted liquid outward through the delivery pipe 15 at the output end.

[0042] Liquid flow restriction assembly 14 is located within delivery pipe 15 and controls the flow of liquid by changing the flow cross-sectional area within delivery pipe 15 or creating a certain resistance to liquid flow. For example, liquid flow restriction assembly 14 functions as a throttle valve. By adjusting the valve opening, the size of the gap through which liquid passes can be changed, thereby controlling the amount of liquid passing through delivery pipe 15 per unit time.

[0043] The liquid drainage component 1 is located inside the working cylinder 26, guiding 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 the situation where the liquid is retained or flows unevenly in the working cylinder 26.

[0044] In one 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.

[0045] 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.

[0046] In agricultural irrigation, the water source may contain impurities such as silt, weeds, and debris. Filter plate 16, located below flow restrictor plate 17, intercepts these impurities, preventing them from continuing to flow with the water flow. This prevents them from clogging the liquid sprinkler 22, helping to maintain the normal operation of the sprinkler 22 and ensuring uniform and effective irrigation. For example, if impurities enter the sprinkler 22, they may damage the internal structure of the sprinkler, such as the spray holes. Filter plate 16 can mitigate this risk, extending the service life of the sprinkler system and reducing maintenance costs.

[0047] Liquid sprinklers 22 evenly spray water, after flow control by flow restrictor 17 and filtration by filter plate 16, onto the farmland. Uniform irrigation helps crops absorb water evenly, ensuring consistent crop growth. For example, for densely planted crops, uniform irrigation ensures that each plant receives the appropriate amount of water, preventing localized waterlogging or drought.

[0048] In one possible embodiment, a support rod 23 is provided on the outside 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 provided 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 provided on the outside of the liquid pump 20.

[0049] 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. 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 more irrigation operations can be achieved with the same amount of initial liquid, thereby improving the working efficiency and equipment utilization of the entire sprinkler irrigation device.

[0050] At the same time, the liquid holding frame 24 below the nozzle can redistribute the liquid sprayed by the nozzle to a certain extent. For example, if the nozzle sprays unevenly in a certain area, the liquid collected by the liquid holding frame 24 can be redistributed and sprayed to compensate for some of the uneven spraying, making irrigation more uniform within a certain range, which is beneficial to the growth of crops.

[0051] In a possible embodiment, 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 lines.

[0052] In the specific application of the embodiment of the present invention, the electric telescopic device 3, the drive motor 8 and the liquid pump 20 used in this device are all mature existing technologies. The working principles of the electric telescopic device 3, the drive 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.

[0053] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0054] The present invention and its embodiments are described above. This 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 a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
