Description

Technical Field

[0001] This utility model belongs to the technical field of sprinkler irrigation devices, and in particular relates to a high-efficiency sprinkler irrigation device for farmland. Background Technology

[0002] In the field of agricultural production, irrigation is a key link to ensure crop growth and increase yield. As the core equipment of modern agricultural irrigation, sprinkler irrigation devices directly affect agricultural production benefits in terms of irrigation efficiency and coverage. With the rapid development of large-scale agriculture, the traditional fixed sprinkler irrigation mode has gradually become unable to meet the irrigation needs of modern farmland. Existing fixed sprinklers mostly employ a point-to-point direct irrigation method, whose lateral coverage is strictly limited by the sprinkler's spray angle. To achieve full coverage of large areas of farmland, a large number of sprinklers often need to be densely arranged. This not only significantly increases the cost of equipment purchase and installation but also increases the difficulty of later maintenance due to the complexity of pipeline laying. To solve the problem of insufficient coverage, some rotary sprinkler irrigation devices have emerged. However, these devices mostly adopt a continuous rotation working mode, which has revealed obvious defects in practical applications: during rotation, the sprinkler quickly sweeps across the edge areas of the farmland, resulting in insufficient irrigation water in those areas and uneven irrigation; while staying in the center area for too long can easily cause local water accumulation, which not only wastes water resources but may also affect crop root growth and reduce irrigation efficiency and quality. Therefore, a high-efficiency sprinkler irrigation device for farmland is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency sprinkler irrigation device for farmland. By incorporating a rotating component, specifically, a motor drives a half-gear to rotate via a rotating shaft, which meshes with a gear ring on the inner side of a fixed disk. Since the turntable is welded to the bottom of a support frame, and the motor is welded to the inner wall of the support frame via a motor mount, the half-gear drives the support frame and turntable to move via the gear ring. The turntable drives a rotating rod to rotate within the fixed disk, thereby causing the support frame to rotate synchronously. Simultaneously, the half-gear causes the irrigation nozzle to rotate intermittently around the rotating rod. This solves the problem that existing fixed sprinklers mostly use a point-to-point direct-spray irrigation method, whose lateral coverage is strictly limited by the nozzle's spray angle. To achieve irrigation over large areas of farmland... Full coverage often requires a dense arrangement of numerous sprinklers, which not only significantly increases equipment purchase and installation costs but also leads to increased maintenance difficulties due to complex pipeline laying. To address the problem of insufficient coverage, some rotary sprinkler systems have emerged. However, these systems mostly operate in a continuous rotation mode, revealing significant drawbacks in practical applications: during rotation, the sprinklers quickly sweep across the edge areas of farmland, resulting in insufficient irrigation water and uneven irrigation in those areas; while spending too much time in the center of rotation can easily cause localized water accumulation, wasting water resources and potentially affecting crop root growth, thus reducing irrigation efficiency and quality.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a high-efficiency sprinkler irrigation device for farmland, comprising a supporting base with four externally threaded pins threaded to its inner edge. An irrigation nozzle is mounted above the supporting base, and the water inlet of the nozzle is rotatably connected to a water pipe via a connector. The device also includes an irrigation mechanism that achieves efficient irrigation by intermittently rotating and reciprocatingly rotating the irrigation nozzle. The irrigation mechanism includes a rotating component comprising a supporting frame and a turntable. A fixed plate is positioned below the turntable. The bottom of the supporting frame is welded to the top of the turntable. A motor is housed inside the cavity of the supporting frame, and the motor is externally connected to the support frame via a motor mount. The inner wall of the support frame is welded, and a gear ring is welded to the inner wall of the fixed disk. The inner ring of the gear ring is meshed with a half gear, and a rotating shaft is welded inside the half gear. The bottom output end of the motor is connected to the top of the rotating shaft through a coupling. The irrigation mechanism also includes a linkage component, which is connected to the rotating shaft and is used to transmit the power of the rotating component. A swing component is connected to the linkage component and is used to reciprocate the up and down rotation of the irrigation nozzle through the linkage component. A rotating rod is welded to the bottom of the turntable, and the outer surface of the rotating rod is rotatably connected to the inside of the fixed disk. The rotating shaft passes through the turntable and extends into the cavity of the fixed disk.

[0005] Furthermore, an adjusting rod is welded to the top of the support base, the top of the adjusting rod is welded to the bottom of the fixed plate, a photovoltaic solar panel is mounted on the outer surface of the adjusting rod via a bracket, a battery is connected to the photovoltaic solar panel via a circuit, the battery is connected to the adjusting rod via bolts, and a moving wheel is connected to the bottom of the support base via a hinge block.

[0006] Furthermore, the linkage component includes a pulley assembly disposed inside the cavity of the support frame. The support frame is welded to the outer surface of the rotating shaft. A rotating rod three is connected to the end of the pulley assembly away from the rotating shaft. The bottom of the outer surface of the rotating rod three is rotatably connected to the inside of the turntable. A bevel gear two is welded to the top of the outer surface of the rotating rod three. A bevel gear one is meshed with the outer surface of the bevel gear two. A rotating rod two is welded inside the bevel gear one. The rotating rod two penetrates the support frame and extends to the back side.

[0007] Furthermore, the swing assembly includes an eccentric disk disposed on the back of the support frame. The center of the eccentric disk is welded to the outer surface of the rotating rod. A drive rod is connected to the edge of the back of the eccentric disk via a pin. The end of the drive rod away from the eccentric disk is connected to a connecting rod via a pin. The end of the connecting rod away from the drive rod is connected to a nozzle bracket via a pin. The nozzle bracket is disposed at the top of the cavity inside the support frame. The top of the nozzle bracket is bolted to the outer surface of the irrigation nozzle. The interior of the nozzle bracket is rotatably connected to the edge of the support frame via a pin.

[0008] This utility model has the following beneficial effects: This invention features a rotating assembly. Specifically, a motor drives a half-gear to rotate via a rotating shaft, which meshes with a gear ring on the inner side of a fixed disk. Since the turntable is welded to the bottom of the support frame, and the motor is welded to the inner wall of the support frame via a motor mount, the half-gear drives the support frame and the turntable to move via the gear ring. The turntable drives a rotating rod to rotate within the fixed disk, thereby causing the support frame to rotate synchronously. Simultaneously, the half-gear causes the irrigation nozzle to rotate intermittently around the rotating rod, expanding the lateral coverage area and optimizing irrigation efficiency.

[0009] This invention utilizes a swing assembly. Specifically, when the shaft rotates, the rotation is transmitted to the rotating rod three via a pulley system. The top bevel gear two of the shaft meshes perpendicularly with the end bevel gear one of the rotating rod two to achieve a 30° turn, driving the eccentric disk to rotate. The eccentric disk converts the circular motion into a reciprocating linear motion of the connecting rod via a drive rod. This connecting rod is hinged to the nozzle bracket and pushes it to swing up and down, causing the irrigation nozzle to spray at a longitudinal angle. Combined with the intermittent revolution of the irrigation nozzle, it takes into account both surface moisture retention and water replenishment needs of the middle and lower parts of the crop, significantly improving irrigation quality.

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.

[0015] Please see Figures 1-5As shown, this utility model is a high-efficiency sprinkler irrigation device for farmland, including a support base 111. Four externally threaded ground pins 112 are threaded onto the inner edge of the support base 111. An irrigation nozzle 116 is mounted above the support base 111. The water inlet of the irrigation nozzle 116 is rotatably connected to a connecting water pipe 117 via a connector. It also includes an irrigation mechanism 2. The irrigation mechanism 2 achieves high-efficiency irrigation by intermittently rotating and reciprocatingly rotating the irrigation nozzle 116. The irrigation mechanism 2 includes a rotating component 21, which includes a support frame 211.

The bottom output end of the motor 214 is connected to the top of the rotating shaft 216 via a coupling. The irrigation mechanism 2 also includes a linkage component 22. The linkage component 22 is connected to the rotating shaft 216 and is used to transmit the power of the rotating component 21. The swing component 23 is connected to the linkage component 22 and is used to rotate the irrigation nozzle 116 up and down through the linkage component 22. The bottom of the turntable 212 is welded with a rotating rod 219, the outer surface of which is rotatably connected to the inside of the fixed plate 213. The rotating shaft 216 passes through the turntable 212 and extends into the cavity of the fixed plate 213. The starter motor 214 drives the half gear 2 via the rotating shaft 216. 17 rotates, meshing with the gear ring 218 on the inner side of the fixed disk 213; since the turntable 212 is welded to the bottom of the support frame 211, and the motor 214 is welded to the inner wall of the support frame 211 via the motor base 215, the half gear 217 drives the support frame 211 and the turntable 212 to move through the gear ring 218; the turntable 212 drives the rotating rod 219 to rotate in the fixed disk 213, thereby driving the support frame 211 to rotate synchronously; at the same time, the half gear 217 causes the irrigation nozzle 116 to rotate intermittently around the rotating rod 219, expanding the lateral coverage area and optimizing irrigation efficiency.

[0016] An adjusting rod 113 is welded to the top of the support base 111. The top of the adjusting rod 113 is welded to the bottom of the fixed plate 213. A photovoltaic solar panel 114 is mounted on the outer surface of the adjusting rod 113 via a bracket. A battery 115 is connected to the photovoltaic solar panel 114 via a circuit. The battery 115 is connected to the adjusting rod 113 via bolts. A moving wheel 118 is connected to the bottom of the support base 111 via a hinge block.

[0017] The linkage assembly 22 includes a pulley assembly 221, which is disposed inside the cavity of the support frame 211. The support frame 211 is welded to the outer surface of the rotating shaft 216. A rotating rod 225 is connected to the end of the pulley assembly 221 away from the rotating shaft 216. The bottom of the outer surface of the rotating rod 225 is rotatably connected to the inside of the turntable 212. A bevel gear 224 is welded to the top of the outer surface of the rotating rod 225, and a bevel gear is meshed with the outer surface of the bevel gear 224. A rotating rod 223 is welded inside the bevel gear 222. The rotating rod 223 passes through the support frame 211 and extends to the back. The swing assembly 23 includes an eccentric disk 231, which is located on the back of the support frame 211. The center of the eccentric disk 231 is welded to the outer surface of the rotating rod 223. A drive rod 232 is connected to the edge of the back of the eccentric disk 231 by a pin. The end of the drive rod 232 away from the eccentric disk 231 is connected to a connecting rod 233 by a pin. The end of the connecting rod 233 away from the drive rod 232 is connected to a nozzle bracket 234 by a pin. The nozzle bracket 234 is located at the top of the cavity inside the support frame 211. The top of the nozzle bracket 234 is bolted to the outer surface of the irrigation nozzle 116. The inside of the nozzle bracket 234 is rotatably connected to the edge of the support frame 211 by a pin. When the rotating shaft 216 rotates, the rotation is transmitted to the rotating rod 225 via the pulley set 221. The top of the rotating rod 225 is connected to the bevel gear 223. 224 meshes perpendicularly with the bevel gear 222 at the end of the rotating rod 223 to achieve a 90° turn, driving the eccentric disk 231 to rotate. The eccentric disk 231 converts the circular motion into the reciprocating linear motion of the connecting rod 233 through the driving rod 232. The connecting rod 233 is hinged to the nozzle bracket 234 and pushes it to swing up and down, driving the irrigation nozzle 116 to spray longitudinally at a variable angle. Combined with the intermittent revolution of the irrigation nozzle 116, it takes into account both the surface moisture retention and the water replenishment needs of the middle and lower parts of the crop, significantly improving the irrigation quality.

[0018] A specific application of this embodiment is as follows: When in use, the user first pushes the device to a suitable location using the moving wheels 118 according to irrigation needs, and then rotates each external threaded pin 112 clockwise to fix it in the soil. The device can be fixed by the external threaded pins 112. At the same time, the user can also adjust the height of the irrigation nozzle 116 by adjusting the support rod 113 according to the irrigated crops. The water pipe 117 continuously supplies water to the irrigation nozzle 116, and the water pipe 117 and the irrigation nozzle 116 are rotatably connected by a connector. During the use of the device, the photovoltaic solar panel 114 converts solar energy into electrical energy and stores it in the battery 115. The battery 115 provides electrical energy output for the use of the device. During use, the starter motor 214 drives the rotating shaft 216 to rotate. As the rotating shaft 216 rotates, it simultaneously drives the half gear 217 to rotate. The half gear 217 meshes with the gear ring 218 fixed inside the fixed disk 213. When the half gear 217 rotates, because the turntable 212 is welded to the bottom of the adjusting support frame 211, and the motor 214 is fixed to the inner wall of the support frame 211 via the motor base 215, when the motor 214 drives the half gear 217 to rotate via the rotating shaft 216, the half gear 217, through the action of the gear ring 218, rotates via the rotating shaft 216 and the motor... The base 215 drives the support frame 211 and the turntable 212 to move. At this time, the turntable 212 drives the rotating rod 219 to rotate inside the fixed plate 213. The support frame 211 and the turntable 212 also rotate with the rotating rod 219. Meanwhile, the support frame 211 drives the irrigation nozzle 116 to rotate intermittently around the rotating rod 219 through the action of the half gear 217. Compared with the fixed point direct spray of the fixed nozzle, it can greatly expand the lateral coverage area. The intermittent design can reduce the problem of the edge quickly sweeping over and the center staying for too long due to continuous rotation, thus improving irrigation efficiency. Simultaneously, as the rotating shaft 216 rotates, power is transmitted to the rotating rod 225 via the pulley assembly 221. The pulley assembly 221 enables long-distance power transmission. The bevel gear 224 at the top of the rotating rod 225 meshes with the bevel gear 222 at the end of the rotating rod 223. The vertical meshing of the bevel gears achieves a 90° turn in the power direction. The rotating rod 223 drives the eccentric disk 231 to rotate. When the eccentric disk 231 rotates, the circular motion is converted into the reciprocating linear motion of the connecting rod 233 via the drive rod 232. The other end of the connecting rod 233 is hinged to the nozzle bracket 234. The reciprocating linear motion drives the nozzle bracket to rotate up and down around the hinge point, ultimately driving the irrigation nozzle 116 to complete the reciprocating up and down swing, realizing the change of the longitudinal irrigation angle and changing the longitudinal spray angle of the water flow. This solves the problem that fixed-angle nozzles cannot simultaneously retain moisture in the surface soil and replenish water to the middle and lower leaves of the crop. Combined with the intermittent revolution of the irrigation nozzle 116, the irrigation quality is greatly improved.
