Description

Technical Field

[0001] This invention belongs to the field of agricultural irrigation equipment technology, specifically relating to an agricultural irrigation spraying device for agricultural production. It is suitable for irrigation operations of various crops in agricultural production, and can achieve precise spraying and convenient cleaning of the filter screen, adapting to the usage needs of different irrigation scenarios. Background Technology

[0002] In agricultural production, irrigation is a crucial step in ensuring the normal growth of crops. As a core irrigation device, agricultural irrigation sprinkler systems directly affect irrigation quality and agricultural production efficiency due to their spraying efficiency, stability, and ease of maintenance. Most existing agricultural irrigation sprinkler systems employ fixed nozzles and a single filter structure. Over long-term use, the filter components are easily clogged by impurities in the water, leading to poor water flow, uneven spraying, and ultimately, reduced irrigation effectiveness.

[0003] Currently, cleaning most filter components requires disassembly and manual cleaning, which is cumbersome, time-consuming, and prone to damaging the sealing structure during disassembly, leading to leaks and reducing the device's lifespan. Meanwhile, some irrigation devices that can perform online cleaning suffer from incomplete cleaning, severe irrigation interruptions during cleaning, and water waste, making it difficult to balance irrigation continuity with effective filtration. Summary of the Invention

[0004] The purpose of this invention is to provide an agricultural irrigation spraying device for agricultural production, so as to solve the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: an agricultural irrigation spraying device for agricultural production, comprising an outer pipe and a sealed inner pipe that is coaxially and slidably fitted with the outer pipe, wherein a driving and adjusting component is provided between the outer pipe and the sealed inner pipe, and the driving and adjusting component is used to drive the sealed inner pipe to rotate and move up and down; The driving and adjusting components include a rotating rod, a C-shaped driving frame, a driving shaft, and a rounded rectangular guide groove; the inner sealed tube has an opening on its side, the rotating rod passes through the opening and the outer tube, and the rotating rod can rotate on the outer tube; The C-shaped drive frame is fixedly connected to one end of the rotating rod located inside the sealed inner tube, and the drive shaft is slidably connected to the inner wall of the C-shaped drive frame, and the drive shaft is fixedly penetrated through the inner wall of the sealed inner tube. The rounded rectangular guide groove is formed on the inner wall of the outer tube. The end of the drive shaft located outside the sealed inner tube is slidably connected to the rounded rectangular guide groove. The rounded rectangular guide groove is composed of two arc-shaped horizontal grooves and two vertical grooves. The rotation of the rotating rod drives the C-shaped drive frame to move, thereby driving the drive shaft to slide along the rounded rectangular guide groove, realizing the rotation and lifting action of the sealed inner tube.

[0005] Preferably, it also includes a filtration and rinsing component, which is disposed inside a sealed inner tube and includes a conical filter screen, a guiding rinsing structure, and a pressure-accumulating rinsing structure; The cone-shaped filter screen is fixedly installed on the inner wall of the sealed inner tube. The upper side of the sealed inner tube has a circumferential outlet, and the connection between the cone-shaped filter screen and the inner wall of the sealed inner tube is located below the outlet. The guiding flushing structure includes multiple circumferentially distributed guide blocks. The guide blocks are fixedly connected to the upper part of the inner wall of the sealed inner tube and fit the convex surface of the conical filter screen. Each guide block is fixedly connected to an inclined plate, which fits the convex surface of the conical filter screen. The ends of the multiple inclined plates away from the guide blocks are fixedly connected to a rotating shaft.

[0006] Preferably, the pressure-accumulating flushing structure includes a spring telescopic rod, a frustum-shaped guide tube, a sealing plug, and a trumpet-shaped guide tube. The spring telescopic rod is fixedly connected to the upper end of the rotating shaft, the frustum-shaped guide tube is fixedly connected to the top of the spring telescopic rod, the sealing plug is fixedly connected above the frustum-shaped guide tube, and the guide tube is sleeved on the outer wall of the sealing plug and located outside the frustum-shaped guide tube. The lower ends of the two form a guide gap. A bearing is fixedly sleeved at the bottom of the guide tube, and an inclined plate is fixedly connected to the outer ring of the bearing. The inclined plate is fixed on the inclined plate. An annular sealing tube is fixedly connected to the top of the guide tube, and a conical guide tube fixed to the upper side of the inner wall of the outer tube is sleeved on the outside of the annular sealing tube.

[0007] Preferably, it also includes a main support component. The outer tube has multiple inclined drainage outlets circumferentially opened on its side, and the number of drainage outlets corresponds to the number of outlets on the sealed inner tube. In the initial state, the two are staggered. A nozzle is fixedly installed at the bottom of the outer tube, and a sealing plate is fixedly connected to the bottom of the inner wall of the sealed inner tube through a connecting rod. An auxiliary sealing tube fixed to the bottom of the inner wall of the outer tube is sleeved on the outer wall of the sealing plate.

[0008] Preferably, it also includes a limiting component, wherein a notch plate is fixedly connected to the outer wall of the guide tube, and the notch plate is slidably disposed on the protrusion on the inner wall of the outer tube; a sealing plate fixed to the inner wall of the outer tube is abutted in the notch of the notch plate.

[0009] Preferably, it also includes a sealing component, wherein an annular groove is provided in the middle of the outer side of the sealing inner tube, and a sealing rubber ring is sleeved in the annular groove; an annular sealing ring is provided on the outer wall of the sealing disc, and the annular sealing ring abuts against the inner wall of the auxiliary sealing tube.

[0010] Preferably, a compression spring is movably sleeved on the outer wall of the rotating rod. One end of the compression spring is fixedly connected to the rotating rod, and the other end is fixedly connected to an abutment plug that is axially movably sleeved on the rotating rod. The abutment plug abuts against the outer wall of the outer tube.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention enables intermittent cleaning of the filter screen without disassembly, improving maintenance convenience. Through the cooperation of a sealed inner tube, rotating rod, C-shaped drive frame, drive shaft, and rounded rectangular guide groove, simply rotating the rotating rod drives the sealed inner tube to rotate and lift, aligning the outlet of the sealed inner tube with the drain outlet of the outer tube to form a drainage channel. Cleaning of the conical filter screen can be completed without disassembling the device. Simultaneously, the pressure-accumulating effect of the spring telescopic rod, sealing plug, and guide tube achieves intermittent impact rinsing of the conical filter screen surface, providing sufficient cleaning power to effectively remove impurities from the filter screen edges and surface, preventing clogging. Compared to traditional manual disassembly and cleaning methods, this significantly saves labor and time costs, and does not damage the device's sealing structure, extending the device's service life.

[0012] This invention ensures irrigation continuity and stability while reducing water waste. During the cleaning process, the sealing cooperation between the sealing disc and the auxiliary sealing pipe blocks the water flow channel of the nozzle, preventing water from flowing out of the nozzle and causing waste. Simultaneously, the double sealing cooperation of the annular sealing pipe, the conical guide pipe, the notch plate, and the sealing plate ensures a stable water supply to the sealed inner pipe during cleaning, providing sufficient power for flushing impurities. Local cleaning can be completed without interrupting the overall irrigation operation, balancing irrigation continuity and cleaning effectiveness. Furthermore, the cooperation of the conical filter screen, the guide block, and the inclined plate efficiently filters impurities in the water while guiding the water flow smoothly, preventing the filtration structure from affecting the irrigation water flow rate and spray pressure, thus ensuring spray stability.

[0013] This invention features a sealing rubber ring that forms a circumferential seal on the drain outlet after the device is reset, blocking the sewage channel and preventing water leakage during irrigation. The combination of the contact plug and the compression spring seals the rotating connection between the rotating rod and the outer pipe. The annular sealing ring on the outer wall of the sealing disc enhances the sealing effect with the auxiliary sealing pipe. The multiple sealing structures effectively prevent water leakage, ensure stable irrigation pressure, and further improve irrigation efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1 to 7 The present invention provides a technical solution: an agricultural irrigation spraying device for agricultural production, including an outer pipe 1, a plurality of inclined drainage outlets 2 are provided on the side of the outer pipe 1, and a nozzle 3 is fixedly installed at the bottom of the outer pipe 1. A sealing inner tube 4 is slidably disposed on the middle part of the inner wall of the outer tube 1, and the sealing inner tube 4 is coaxially disposed with the outer tube 1. An opening 41 is opened on the side of the sealing inner tube 4, and a rotating rod 42 passes through the opening 41. The rotating rod 42 passes through the outer tube 1 and can rotate on the outer tube 1. A C-shaped drive frame 43 is fixedly connected to one end of the rotating rod 42 inside the sealing inner tube 4. A drive shaft 44 is slidably connected to the inner wall of the C-shaped drive frame 43, and the drive shaft 44 is fixedly passed through the inner wall of the sealing inner tube 4. The drive shaft 44 has one end located outside the sealed inner tube 4 and slides in the rounded rectangular guide groove 45 opened on the inner wall of the outer tube 1; the rounded rectangular guide groove 45 consists of two horizontal grooves and two vertical grooves, and the two horizontal grooves are arc-shaped.

[0018] A connecting rod is fixedly connected to the bottom of the inner wall of the inner sealing tube 4, and a sealing plate 46 is fixedly connected to the bottom of the connecting rod. An auxiliary sealing tube 47 is sleeved on the outer wall of the sealing plate 46 and is fixed to the bottom of the inner wall of the outer tube 1. Multiple outlets 48 are circumferentially opened on the upper side of the inner wall of the sealed inner tube 4. The number of outlets 48 corresponds to the number of drain outlets 2 and they are staggered with each other. A cone-shaped filter screen 49 is fixedly installed on the inner wall of the sealed inner tube 4, and the connection between the cone-shaped filter screen 49 and the inner wall of the sealed inner tube 4 is located below the outlet 48.

[0019] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 7 As shown, multiple circumferentially distributed guide blocks 5 are fixedly connected to the upper part of the inner wall of the sealed inner tube 4. The guide blocks 5 assist the water source to be discharged through the outlet 48, which facilitates better discharge of impurities. The number of guide blocks 5 corresponds to the number of outlets 48. The guide blocks 5 are attached to the convex surface of the conical filter screen 49. An inclined plate 51 is fixedly connected to the guide block 5. The inclined plate 51 is attached to the convex surface of the conical filter screen 49. The inclined plate 51 has a flow guiding function. A rotating shaft 52 is fixedly connected to one end of the multiple inclined plates 51 away from the guide blocks 5. A spring telescopic rod 53 is fixedly connected to the upper end of the rotating shaft 52. The rotating shaft 52 ensures that the spring telescopic rod 53 does not rotate when the sealed inner tube 4 is rotated. A frustum guide tube 54 is fixedly connected to the top of the spring telescopic rod 53. A sealing plug 55 is fixedly connected above the frustum guide tube 54. The outer wall of the sealing plug 55 is fitted with a guide tube 56, which is funnel-shaped. The guide tube 56 is outside the frustum guide tube 54, and a guide gap is formed between the lower end of the guide tube 56 and the lower end of the frustum guide tube 54 to guide the flow of water. A bearing 57 is fixedly sleeved at the bottom of the guide tube 56. An inclined plate 58 is fixedly connected to the outer ring of the bearing 57, and the inclined plate 58 is fixed on the inclined plate 51. The bearing 57 ensures that the guide tube 56 does not rotate when the inner sealing tube 4 rotates.

[0020] The top of the guide tube 56 is fixedly connected to an annular sealing tube 59, and a conical guide tube 510 is sleeved on the outer wall of the annular sealing tube 59. The conical guide tube 510 is fixed on the upper side of the inner wall of the outer tube 1.

[0021] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 7 As shown, a notch plate 6 is fixedly connected to the outer wall of the guide tube 56. The notch plate 6 is slidably set on the protrusion on the inner wall of the outer tube 1 to prevent the notch plate 6 from rotating.

[0022] The notch of the notch plate 6 is in contact with the sealing plate 61, and the sealing plate 61 is fixed to the inner wall of the outer tube 1.

[0023] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 7As shown, an annular groove is opened in the middle of the outer side of the inner sealing tube 4, and a sealing rubber ring 7 is fitted inside the annular groove. The sealing rubber ring 7 is used to seal the drain outlet 2 in a circumferential manner after the inner sealing tube is reset and moved upward, thus blocking the sewage discharge channel.

[0024] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 7 As shown, an annular sealing ring is provided on the outer wall of the sealing disc 46, and the annular sealing ring abuts against the inner wall of the auxiliary sealing tube 47.

[0025] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 7 As shown, a compression spring 8 is movably sleeved on the outer wall of the rotating rod 42. One end of the compression spring 8 is fixedly connected to the rotating rod 42, and the other end of the compression spring 8 is fixedly connected to an abutment plug 9. The abutment plug 9 is axially movably sleeved on the rotating rod 42 and abuts against the outer wall of the outer tube 1 to seal the rotation point between the rotating rod 42 and the outer tube 1.

[0026] The method of use and advantages of this invention: The working process of this agricultural irrigation spraying device for agricultural production is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 7 As shown, when the device is in use, it is connected to the water pipe through the outer pipe 1, and water is supplied to the outer pipe 1 through the water pipe. The water source enters the cone-shaped guide pipe 510, enters the sealed inner pipe 4 through the notch of the notch plate 6, and flows into the auxiliary sealing pipe 47 after being filtered by the cone-shaped filter screen 49. Finally, it is discharged through the nozzle 3 to spray the area that needs to be sprayed. When the device has been used for a period of time, it is necessary to clean the impurities filtered by the edge of the cone-shaped filter screen 49; by rotating the rotating rod 42, the rotating rod 42 and the C-shaped drive frame 43 are engaged to drive the drive shaft 44 to deflect circumferentially in the rounded rectangular guide groove 45, causing the inner sealing tube 4 to rotate horizontally inside the outer tube 1. At this time, the outlet 48 on the inner sealing tube 4 is axially aligned with the drain outlet 2 on the outer tube 1. Then, the drive shaft 44 moves vertically downward in the rounded rectangular guide groove 45, causing its upper outlet 48 to align and connect with the upper drain outlet 2 of the outer pipe 1, forming a sewage discharge channel, which facilitates the subsequent rinsing of the impurities filtered by the edge of the cone-shaped filter screen 49. Furthermore, as the inner sealed tube 4 moves downward, the downward movement of the inner sealed tube 4 causes the annular sealing tube 59 on the guide tube 56 to be squeezed into the conical guide tube 510, ensuring that subsequent water sources are transported into the inner sealed tube 4 through the annular sealing tube 59. At the same time, the notch plate 6 on the outer side of the guide pipe 56 moves down and abuts against the sealing plate 61 that it cooperates with, thus ensuring a stable water source is transported to the inner sealing pipe 4 through the annular sealing pipe 59. Finally, the sealing disc 46 connected to the lower end of the sealing inner tube 4 moves down into the auxiliary sealing tube 47 to seal the auxiliary sealing tube 47, preventing water from flowing out of the nozzle 3 when cleaning the cone-shaped filter screen 49. At this time, water is supplied into the outer pipe 1, and the water is gradually pressurized into the annular sealing pipe 59, which causes the sealing plug 55 to move down in the guide pipe 56 and compress the spring telescopic rod 53. When the sealing plug 55 separates from the guide pipe 56, the pressurized water in the guide pipe 56 will flow obliquely along the channel between the frustum guide pipe 54 and the guide pipe 56 to wash the surface of the cone filter screen 49, and discharge the impurities on the surface of the cone filter screen 49 through the outlet 48 and the drain outlet 2. This is to wash the surface of the cone filter screen 49 without disassembling the device. After the water in the guide pipe 56 has been pressurized and flowed out, the sealing plug 55 moves upward under the restoring force of the spring telescopic rod 53 to block the guide pipe 56. After the water in the guide pipe 56 has been pressurized again, the surface of the cone filter screen 49 is rinsed again, forming an intermittent impact cleaning of the cone filter screen 49. After rinsing, the rotating rod 42 is rotated in the opposite direction, causing the rotating rod 42 to drive the drive shaft 44 to move upward in the rounded rectangular guide groove 45 and then deflect. The drive shaft 44 first moves upward along the axial direction of the rounded rectangular guide groove 45, and then deflects circumferentially to reset, so that the outlet 48 and the drain outlet 2 are circumferentially misaligned and closed. At the same time, the annular sealing pipe 59 moves upward and separates from the conical guide pipe 510, and the notch plate 6 moves upward and separates from the sealing plate 61, ensuring that the subsequent water source passes through the gap between the annular sealing pipe 59 and the conical guide pipe 510, and enters the inner sealing pipe 4 with the notch of the notch plate 6. The sealing plate 46 moves upward to release the blockage of the nozzle 3 and complete the device reset.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
