Description

TECHNICAL FIELD

[0001] The present application belongs to the field of agricultural sprinkling irrigation technology, and particularly relates to a sprinkling irrigation equipment. BACKGROUND

[0002] The rotating injector is the core executive component of agricultural irrigation, and its performance directly affects the efficiency of water resource utilization. The core indicators for measuring the performance of the rotating injector are the range and the spraying uniformity. However, there is an inherent technical contradiction between the two: in order to pursue a long range, it is necessary to maximize the bunching and kinetic energy of the water jet, but this will lead to the concentration of water flow and the deterioration of spraying uniformity; on the contrary, in order to improve the uniformity, the jet flow is disturbed and dispersed, which inevitably causes the dissipation of kinetic energy and the shortening of the range.

[0003] The prior art has formed various technical paths to solve this contradiction, but all have significant limitations. The most commonly used is the basic scheme of combining continuous constant rotation mode with fixed water dispersing device. This scheme has a single and static working mode and cannot be dynamically adjusted, forcing the designer to adopt a compromise strategy between the range and the uniformity, and the upper limit of the performance is low. In order to break through this limitation, some improved schemes introduce a manual speed regulation mechanism, allowing users to manually switch the speed gear after stopping. However, the existing speed regulation function is generally limited to two gears, the number of gears is too small, the adjustment granularity is rough, and users cannot make fine selection according to complex field conditions, so the performance improvement is limited. In addition, another scheme attempts to use an intermittent water dispersing device to improve the uniformity, but generally has problems such as low action frequency, slow response, and low water dispersing efficiency, making it difficult to achieve rapid and uniform redistribution of water volume.

[0004] Especially crucially, the existing technology regards speed regulation, rotation mode and water dispersing function as isolated improvement points, lacking a systematic and collaborative design concept. The existing products cannot realize the working mode of intermittent rotation of the speed, i.e., intelligently switching between the static phase of pursuing the maximum range and the rotating phase of achieving full coverage. At the same time, the limited speed regulation capability and the inefficient water dispersing function are disconnected from each other, and cannot cooperatively implement complex irrigation strategies, resulting in that the comprehensive performance is difficult to meet the high standard requirements of precision irrigation.

[0005] Based on the above deficiencies of the prior art, it is difficult to break through the technical bottleneck between the range and the uniformity by a dynamic, accurate and collaborative mechanism. In view of this, there is an urgent need in the art for a rotating injection device with a reasonable structure to achieve high spraying uniformity at the maximum range, thereby improving the efficiency of the injector and the water saving effect.

[0022] Reference Figures 1-9 A sprinkler irrigation device, comprising: The water inlet tank 2 has a flange fixing end at its bottom for connecting to an external water supply pipe; The spray assembly 1 is fixedly installed on the upper part of the water inlet tank 2 and is used to spray water. The drive tube 5 has its inlet end connected to the inside of the water inlet tank 2 and its outlet end extending to the outside of the water inlet tank 2; The drive assembly 4 includes a flywheel 41 and a reduction gearbox 42. The flywheel 41 has multiple radial blades, which are disposed in front of the outlet end of the drive pipe 5, so that the water jet from the drive pipe 5 can impact the blades and drive the flywheel 41 to rotate around a horizontal axis. The flywheel 41 is connected to a drive shaft 43, which extends into the reduction gearbox 42 and is connected to the input end of the multi-stage reduction section 6 disposed inside the reduction gearbox 42. The intermittent rotation component 3 has its input end connected to the output end of the multi-stage reduction section 6 via a transmission shaft 44, and its output end connected to the water inlet tank 2. It is used to convert the continuous rotational motion output by the multi-stage reduction section 6 into periodic intermittent rotational motion, and drive the water inlet tank 2 and the spray component 1 fixed thereon to rotate intermittently in sync. The oscillating component 7 is disposed between the drive pipe 5 and the water inlet tank 2. When the water inlet tank 2 is intermittently rotated to a specific angle, it drives the outlet end of the drive pipe 5 to oscillate relative to the water inlet tank 2, so as to change the direction of the water jet impacting the blades of the flywheel 41, thereby periodically changing the rotation direction of the flywheel 41. The spraying assembly 1 includes at least two stages of nozzles 11 with different inner diameters, forming a multi-stage spraying structure; the irrigation equipment also includes a diversion assembly 8 disposed at the nozzle of the spraying assembly 1, and an intermittent adjustment assembly 9 for driving the diversion assembly 8 to operate periodically.

[0023] In one feasible embodiment, the intermittent rotation assembly 3 includes a grooved wheel 36 and a drive dial mechanism. The grooved wheel 36 is fixedly sleeved on the outside of a vertical pipe 21 at the bottom of the water inlet tank 2. The drive dial mechanism includes a universal joint 31 connected to the end of the drive shaft 44. The universal joint 31 is connected to a cylindrical pin 33 via a universal joint 32. The cylindrical pin 33 is connected to a cylindrical pin 35 via a connecting plate 34. The grooved wheel 36 has at least one radial groove 37, and the cylindrical pin 35 is detachably engaged in the radial groove 37. When the drive shaft 44 drives the cylindrical pin 35 to perform a circular motion, the cylindrical pin 35 drives the grooved wheel 36 and the water inlet tank 2 to rotate a certain angle during the period when it enters the radial groove 37, and the grooved wheel 36 and the water inlet tank 2 remain stationary during the period when it leaves the radial groove 37. The bottom of the water inlet tank 2 is rotatably connected to the flange fixed end set by the outside, so the whole device has a space to rotate, and the rotation range is limited by the limit chuck 711 connected to the fixed end.

[0024] In one feasible embodiment, the multi-stage reduction section 6 includes a worm 61, a worm wheel 62, and a multi-stage reduction gear set. The worm 61 is coaxially and fixedly connected to the drive shaft 43. The worm wheel 62 meshes with the worm 61 and is fixed to the first rotating shaft 63. The multi-stage reduction gear set is disposed inside the reduction gearbox 42, with its input end connected to the first rotating shaft 63 and its output end connected to the second rotating shaft 64. The transmission shaft 44 is linked to the second rotating shaft 64, and the intermittent adjustment component 9 is linked to the first rotating shaft 63.

[0025] As a preferred option, such as Figure 3 As shown, the multi-stage reduction gear set can be configured as a reduction gear set 68 with three different transmission ratios (e.g., 0.75, 0.5, and 0.25). By axially moving the second rotating shaft 64, different reduction gears 69 can engage, thereby achieving speed regulation. Specifically, the axial movement of the second rotating shaft 64 can be achieved by setting a rotating rod 65. The toothed portion 66 at the top of the rotating rod 65 meshes with the toothed shaft 67 on the second rotating shaft 64. Rotating the rotating rod 65 moves the second rotating shaft 64. Given the axial movement requirement of the second rotating shaft 64, a retractable and rotation-transmitting structure is provided at its connection with the transmission shaft 44, such as an interlocking sleeve structure, and mutually cooperating square blocks and square grooves are provided at the connection.

[0026] In one feasible embodiment, the swing assembly 7 includes a rotating platform 72, a limiting platform 71, a trigger rod 75, and a reset elastic element. The rotating platform 72 is rotatably mounted on the bottom of the water inlet tank 2 via a horizontally arranged rotating shaft 74, and the body of the drive pipe 5 is fixedly engaged with the rotating platform 72. The limiting platform 71 is fixedly disposed on the water inlet tank 2 and located in front of the drive pipe 5, and has a limiting groove inside, through which the body of the drive pipe 5 passes. The limiting groove allows the drive pipe 5 to swing laterally within a certain angle range with the rotating platform 72. The trigger rod 75 is fixedly connected to the bottom end of the rotating shaft 74 and rotates with it. A fixed straight rod is vertically fixed to the flange fixing end. When the water inlet tank 2 rotates intermittently, the trigger rod 75 abuts against the fixed straight rod along the rotation path, thereby forcing the rotating shaft 74 to rotate. This causes the rotating platform 72 and the drive pipe 5 to swing, thus changing the direction in which the water jet from the drive pipe 5 impacts the blades of the flywheel 41, achieving a change in the direction of the flywheel 41's rotation. The reset elastic element is used to keep the drive pipe 5 in the neutral position when it is not triggered.

[0027] In one feasible embodiment, the reset elastic element is a tension spring 78, which is disposed within a connecting cylinder 76. One end of the connecting cylinder 76 is hinged to the limiting platform 71 via a pin 79, and the other end is hinged to the rotating shaft 74 via a rotating plate 77. The pin 79 can slide within a transverse groove 710 opened in the side wall of the connecting cylinder 76. The two ends of the tension spring 78 are respectively connected to the pin 79 and the bottom of the connecting cylinder 76. When the rotating shaft 74 rotates due to the trigger rod 75 being abutted, it pulls the connecting cylinder 76 through the rotating plate 77, causing the pin 79 to slide in the transverse groove 710 and stretch the tension spring 78 to store energy. When the water inlet tank 2 rotates past the abutment point, the drive tube 5 has a tendency to swing back under the restoring force of the tension spring 78. In conjunction with the reverse rotation of the entire device after the flywheel 41 changes direction, the swing can be triggered again on the other side, thereby realizing the periodic reciprocating swing of the drive tube 5 and the periodic switching of the flywheel 41's direction.

[0028] In one feasible embodiment, the nozzle 11 includes a main pipe 111 serving as a primary nozzle and a branch pipe 112 serving as a secondary nozzle. The branch pipe 112 has a Y-shaped structure, with its inlet connected to the outlet of the main pipe 111, and its two outlets facing different directions to improve the irrigation coverage.

[0029] In one feasible embodiment, the diversion assembly 8 includes a first diversion component 81 and a second diversion component 82. The first diversion component 81 is rotatably mounted at the outlet of the main pipe 111 via a first rotating plate 83. The second diversion component 82 is rotatably mounted at the two outlets of the branch pipe 112 via two symmetrically arranged second rotating plates 84. The first diversion component 81 and the second diversion component 82 are connected by a linkage, so that they can be driven by the intermittent adjustment assembly 9 to operate synchronously. The linkage can be an elastic rope or a steel rope, thereby adjusting the first diversion component 81 and the second diversion component 82 to work synchronously or asynchronously. The working principle of the diversion component is as follows: when it rotates to the center position of the nozzle, it will block and disperse the main jet, splitting a concentrated water flow into multiple streams, thereby increasing the instantaneous spray area, but sacrificing the range; when it leaves the center of the nozzle, the jet remains concentrated, achieving a longer range.

[0030] In one feasible embodiment, the intermittent adjustment assembly 9 includes a first adjustment gear 91, a second adjustment gear 92, a first winding reel 95, and a traction rope 94. The first adjustment gear 91 is fixed to the first rotating shaft 63 of the multi-stage reduction section 6. The second adjustment gear 92 meshes with the first adjustment gear 91 and is fixed to a fourth rotating shaft 93. The first winding reel 95 is fixed to the fourth rotating shaft 93. One end of the traction rope 94 is wound around the first winding reel 95, and the other end is connected to the first diverting component 81. When the first rotating shaft 63 rotates, the first winding reel 95 is driven by gear transmission to intermittently wind and unwind the traction rope 94, thereby periodically pulling the first diverting component 81 and the second diverting component 82, which is linked by a linkage, to rotate to or away from the center of the nozzle.

[0031] In one feasible embodiment, the first diverter 81 is U-shaped, including a vertical portion 8111 facing the nozzle and a horizontal portion 8112 connected to the top of the vertical portion 8111. The linkage is an elastic pull rope 97, with its two ends connected to the horizontal portion 8112 and the middle of the second diverter 82, respectively. The second diverter 82 is a long rod, long enough to simultaneously block or move away from the two outlets of the branch pipe 112.

[0032] In one feasible embodiment, a limiting chuck 711 is also fixedly installed at the bottom of the water inlet tank 2, and a locking block that cooperates with the limiting chuck 711 is provided on the flange fixing end to limit the maximum rotation angle of the water inlet tank 2, thereby defining the fan-shaped area range of the sprinkler irrigation.

[0033] The working principle of this invention is briefly described as follows: After the high-pressure water flows into the inlet tank 2, a portion is ejected through the drive pipe 5, impacting the blades of the flywheel 41 and driving it to rotate. The rotation of the flywheel 41 is transmitted to the reduction gearbox 42 via the drive shaft 43. After being significantly reduced in speed and increased in torque by the multi-stage reduction section 6, the output is sent to the intermittent rotation component 3 via the transmission shaft 44. The intermittent rotation component 3 converts the continuous input rotation into periodic intermittent output, driving the inlet tank 2 and the entire spray assembly 1 to perform a rotating, paused, and rotating process.

[0034] When the water inlet tank 2 rotates to its limit angle, the trigger rod 75 of the swing assembly 7 abuts against the fixed straight rod, forcing the drive pipe 5 to swing and change the direction of its water impact on the flywheel 41, thereby causing the rotation direction of the flywheel 41, drive shaft 43 and subsequent transmission chain to periodically reverse. After reversal, the intermittent rotation assembly 3 drives the water inlet tank 2 and the spray assembly 1 to rotate intermittently in the opposite direction, and so on, to achieve automatic fan-shaped spraying.

[0035] Simultaneously, the power derived from the first rotating shaft 63 within the gearbox is converted into a periodic pulling motion via the intermittent adjustment component 9, controlling the first and second diverting components 81 and 82 of the diverting component 8 to synchronously and periodically engage or disengage from the various nozzles of the spraying component 1. When the diverting components engage, the jet is dispersed, achieving large-area near-to-mid-range coverage; when the diverting components disengage, the jet remains focused, achieving maximum range. The entire process requires no external electricity, being entirely driven by water pressure, enabling large-scale, high-efficiency, and energy-saving automatic sprinkler irrigation.

[0036] In summary, this invention provides a coordinated sprinkler irrigation device with multi-level speed regulation, intermittent rotation, multi-level compensation, and high-efficiency jet disturbance. It organically integrates and coordinates the functions of multi-level speed regulation, intermittent rotation, multi-level nozzle compensation, and high-efficiency jet disturbance throughout the entire spray range. This allows for intelligent dynamic switching between different operating modes, thereby significantly improving spray uniformity across the entire humidified area while ensuring the maximum spray range, ultimately resulting in a substantial increase in operational efficiency and water conservation.

[0037] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
