Description

Technical Field

[0001] This application relates to the field of irrigation technology, and more particularly to a sprinkler irrigation device. Background Technology

[0002] A sprinkler irrigation system is an irrigation device used in agriculture, horticulture, and landscaping. It works by using high-pressure water jets to atomize water into fine droplets, which are then sprayed evenly onto the surface of crops or plants to achieve irrigation.

[0003] Existing sprinkler irrigation systems consist of components such as water pumps, support assemblies, and pipe assemblies. When in use, the water pump is activated, delivering high-pressure water to the sprinkler pipes within the pipe assembly. The water is then atomized by the atomizing needles and sprayed out from the sprinkler nozzles, thus achieving sprinkler irrigation. However, existing sprinkler irrigation systems have limited functionality, lacking pesticide spraying capabilities, resulting in low utilization rates. Furthermore, pesticide spraying requires separate work by relevant personnel (e.g., using specialized spraying equipment), thereby increasing the workload of these workers. Summary of the Invention

[0004] This application aims to at least partially address one of the technical problems in the related art.

[0005] Therefore, the purpose of this application is to provide a sprinkler irrigation device that can perform both sprinkler irrigation and pesticide spraying functions, thereby improving the utilization rate of the device and reducing the labor intensity of relevant personnel.

[0006] To achieve the above objectives, a first aspect of this application provides a sprinkler irrigation device, including a water pump, a support frame, a first water pipe, a second water pipe, a connecting rod, a rocker arm assembly, and a dosing assembly. The support frame is equipped with a rotary control console, which has a drive groove. One end of the first water pipe is connected to the water pump, and the other end is mounted on the rotary control console and rotatably connected to the second water pipe. The second water pipe is equipped with a first gear and an atomizing needle, one end of which is positioned at the sprinkler inlet of the second water pipe. The rocker arm assembly is rotatably mounted on the second water pipe, with one end rotatably positioned at the sprinkler inlet. One end of the connecting rod is connected to the rocker arm assembly. The other end of the rod is connected to the drive slide groove; the dosing assembly includes a housing, a second gear, a threaded rod, a pressure plate, a one-way valve, a connecting pipe, and an abutment. The housing is slidably mounted on the support frame and is located on one side of the rotary control console; the second gear is rotatably mounted on the housing and slidably meshes with the first gear; the threaded rod is rotatably mounted inside the housing and connected to the second gear; the pressure plate is slidably mounted inside the housing and is rotatably connected to the threaded rod; the one-way valve is connected to the bottom of the housing; one end of the connecting pipe is connected to the one-way valve, and the other end of the connecting pipe is connected to the first water pipe; one end of the abutment is connected to the pressure plate and is slidably and sealingly connected to the housing, and the other end of the abutment is rotatably connected to the rotary control console.

[0007] According to one embodiment of this application, a sprinkler irrigation device can perform both sprinkler irrigation and pesticide spraying functions, thereby improving the utilization rate of the device and reducing the labor intensity of relevant personnel.

[0008] In addition, the sprinkler irrigation device proposed in this application may also have the following additional technical features:

[0009] In one embodiment of this application, the abutment includes a control rod and a telescopic abutment rod, wherein one end of the control rod is connected to the pressure plate and is slidably and sealingly connected to the housing; one end of the telescopic abutment rod is rotatably connected to the control rod, and the other end of the telescopic abutment rod is rotatably connected to the rotary control console.

[0010] In one embodiment of this application, the drive chute includes a drive portion and a recovery portion, which are connected and are arranged in a circumferential array on a rotating control console.

[0011] In one embodiment of this application, the rocker arm assembly includes a mounting rod, a rocker arm bracket, a force-bearing plate, and a counterweight. The mounting rod is rotatably connected to the second water pipe. The rocker arm bracket is connected to the mounting rod, and one end of the rocker arm bracket has a sliding control groove, with one end of the connecting rod slidably connected to the sliding control groove. The force-bearing plate is inclinedly disposed at one end of the rocker arm bracket and rotatably disposed at the spray nozzle of the second water pipe. The counterweight is connected to the other end of the rocker arm bracket.

[0012] In one embodiment of this application, a torsion spring is provided on the mounting rod, the torsion spring is sleeved on the mounting rod, one end of the torsion spring is connected to the rocker arm bracket, and the other end of the torsion spring is connected to the second water pipe.

[0013] The beneficial effects of this application are as follows:

[0014] The rocker arm assembly is intermittently impacted by high-pressure water flow, causing it to reciprocate up and down. This drives the connecting rod to move up and down, allowing it to slide within the drive groove. The second water pipe is controlled to rotate at fixed angles multiple times on the first water pipe, driving the first and second gears to mesh and rotate at fixed angles multiple times. This, in turn, causes the threaded rod to rotate at fixed angles multiple times, and the pressure plate presses down a fixed length each time. Each time, a fixed amount of medicine is pushed from the delivery box into the first water pipe, thus achieving uniform irrigation of the medicine and preventing a large amount of medicine from being sprayed out in a short time, which would cause the medicine to be concentrated in a single area.

[0015] By setting up atomizing needles, high-pressure water jets impact the needles, causing the high-pressure water jets to be dispersed into atomized water droplets, thereby achieving uniform irrigation and pesticide application in the sprinkler system.

[0016] By setting up the abutment, the abutment is used to abut the rotating control console as the pressure plate gradually presses down to the bottom of the housing. This gradually pushes the dosing assembly to slide on the support frame and away from the rotating control console, causing the first gear and the second gear to gradually disengage. When the pressure plate reaches the bottom of the housing, the first gear and the second gear completely disengage. Thus, after the device has finished spraying, the rotation of the first gear no longer controls the idling operation of the dosing assembly, reducing the number of times the dosing assembly is used and wear, and improving the service life of the dosing assembly and the utilization rate of the equipment.

[0017] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0028] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0029] The sprinkler irrigation device according to an embodiment of this application will now be described with reference to the accompanying drawings.

[0030] like Figures 1-8 As shown, the sprinkler irrigation device of this application embodiment may include a water pump 1, a support frame 2, a first water pipe 3, a second water pipe 4, a connecting rod 6, a rocker arm assembly 5, and a dosing assembly 7.

[0031] Among them, the support frame 2 is provided with a rotating control console 20, and the rotating control console 20 is provided with a drive slide groove 200;

[0032] In this embodiment, the drive chute 200 is used to control the rotation of the connecting rod 6 at a fixed angle on the rotary control console 20 (the rotary control console 20 is cylindrical), and to drive the rocker arm assembly 5 to rotate, and to drive the second water pipe 4 to rotate at a fixed angle on the first water pipe 3, thereby realizing the rotational irrigation of the second water pipe 4 and increasing the irrigation area of ​​the device.

[0033] One end of the first water pipe 3 is connected to the water pump 1, and the other end of the first water pipe 3 is set on the rotary control console 20 and is rotatably connected to the second water pipe 4.

[0034] It is understandable that one end of the water pump 1 is connected to a water storage tank or other water source through a pipe to ensure the sprinkler irrigation effect of this device.

[0035] The second water pipe 4 is equipped with a first gear 40 and an atomizing needle 41, with one end of the atomizing needle 41 located at the spray nozzle of the second water pipe 4.

[0036] In this embodiment, the first gear 40 is used to rotate and engage the second gear 71 in the dosing assembly 7, and the second gear 71 performs work to cause the dosing assembly 7 to deliver medicine into the first water pipe 3, thereby realizing the water spraying and medicine spraying functions of this device.

[0037] It should be noted that the atomizing needle 41 described in this embodiment is a component commonly used in sprinkler irrigation devices on the market. One end of the needle is set at the irrigation nozzle (not shown in the figure), so that the high-pressure water flow impacts the atomizing needle 41, causing the high-pressure water flow to be dispersed into atomized water droplets, thereby achieving uniform irrigation of the sprinkler irrigation device.

[0038] Understandably, the atomizing needle 41 enables the device to achieve uniform irrigation and pesticide spraying.

[0039] The rocker arm assembly 5 is rotatably mounted on the second water pipe 4, and one end of the rocker arm assembly 5 is rotatably mounted at the spray nozzle of the second water pipe 4.

[0040] In this embodiment, the rocker arm assembly 5 is intermittently impacted by high-pressure water flow, causing it to reciprocate up and down on the second water pipe 4. The up and down movement of the rocker arm assembly 5 can drive the connecting rod 6 to slide within the drive groove 200. The connecting rod 6 drives the rocker arm assembly 5 and the second water pipe 4 to rotate, thereby realizing large-area irrigation of this device.

[0041] One end of the connecting rod 6 is connected to the rocker arm assembly 5, and the other end of the connecting rod 6 is connected to the drive slide 200.

[0042] In this embodiment, the connecting rod 6 is used to convert the up-and-down reciprocating motion of the rocker arm assembly 5 into multiple fixed-angle circular motions of the second water pipe 4 on the first water pipe 3 through the driving slide 200, thereby realizing large-area irrigation of the irrigation area by this device.

[0043] It should be noted that the connecting rod 6 described in this embodiment is connected to the drive slide groove 200 through the tooth surface of the first gear 40, and the first gear 40 is provided with a through hole (not shown in the figure) through which the connecting rod 6 passes, thereby ensuring the rotation control of the rocker arm assembly 5 and the second water pipe 4 by the connecting rod 6, and preventing the connecting rod 6 from bending in the middle after long-term use.

[0044] The dosing assembly 7 may include a housing 70, a second gear 71, a threaded rod 72, a pressure plate 73, a one-way valve 74, a connecting pipe 75, and an abutment member 76.

[0045] The housing 70 is slidably mounted on the support frame 2 and is located on one side of the rotating control console 20.

[0046] It should be noted that the box 70 described in this embodiment is provided with a medicine inlet (not shown in the figure) and a cleaning drain outlet (not shown in the figure). The bottom of the box 70 is provided with support legs (not shown in the figure), which are slidably connected to the support frame 2. The support legs facilitate the abutment work of the abutment member 76. The top plate of the box 70 (not shown in the figure) is detachable, which facilitates the cleaning and maintenance of the box 70. The medicine inlet and the cleaning drain outlet are closed during operation, thereby ensuring that the medicine flows from the one-way valve 74 and the connecting pipe 75 into the first water pipe 3.

[0047] It should be noted that the dosing assembly 7 described in this embodiment is slidably mounted on the support frame 2, and the support frame 2 is tilted to prevent the dosing assembly 7 from sliding on its own, causing the second gear 71 to disengage from the first gear 40. The dosing assembly 7, when filled with liquid, has a certain weight, which increases the sliding friction between the dosing assembly 7 and the support, further preventing the dosing assembly 7 from sliding on its own. As the liquid is gradually discharged, the weight of the dosing assembly 7 decreases significantly, further reducing the sliding friction between the dosing assembly 7 and the support, thus facilitating the contact control of the abutment member 76 and reducing the force required for the rocker arm assembly 5 to move downwards. Additionally, to prevent the dosing assembly 7 from sliding on the support, a limiting spring (not shown in the figure) can be installed on the leg portion of the housing 70. One end of the limiting spring is connected to the support frame 2, and the other end elastically abuts against the leg portion of the housing 70.

[0048] It is understandable that by sliding the housing 70 and the support frame 2, after the device finishes spraying, the second gear 71 is no longer connected to the first gear 40 and is no longer continuously driven by the first gear 40 to do useless work, thereby ensuring the rotational irrigation effect of the second water pipe 4 and the service life of the dosing component 7.

[0049] The second gear 71 is rotatably mounted on the housing 70 and slides into engagement with the first gear 40.

[0050] It is understandable that the sliding connection between the housing 70 and the support frame 2 enables the sliding engagement of the first gear 40 and the second gear 71. The engagement of the first gear 40 and the second gear 71 drives the threaded rod 72 to rotate, thereby causing the pressure plate 73 to move downward. The pressure plate 73 then transports the drug mixture from the one-way valve 74 and the connecting pipe 75 into the first water pipe 3, and sprays it out with the water in the first water pipe 3, thus realizing the spraying function of this device.

[0051] Understandably, the intermittent impact of high-pressure water flow on the rocker arm assembly 5 causes it to reciprocate up and down, driving the connecting rod 6 to move up and down. This causes the connecting rod 6 to slide within the drive groove 200, controlling the second water pipe 4 to rotate at fixed angles multiple times on the first water pipe 3. This drives the first gear 40 and the second gear 71 to mesh and rotate at fixed angles multiple times, thereby causing the threaded rod 72 to rotate at fixed angles multiple times. The pressure plate 73 presses down a fixed length each time, pushing a fixed amount of pesticide from the delivery box 70 into the first water pipe 3 each time. This achieves uniform pesticide spraying, preventing a large amount of pesticide from spraying out in a short time, which would cause the pesticide to be concentrated in a single area. In addition, relevant personnel can adjust the concentration ratio of the pesticide in the box 70 according to the fixed amount of pesticide delivered by the pressure plate 73, thereby ensuring the effectiveness of the pesticide on the crop.

[0052] The threaded rod 72 is rotatably disposed inside the housing 70 and connected to the second gear 71. The pressure plate 73 is slidably disposed inside the housing 70 and is rotatably connected to the threaded rod 72.

[0053] It should be noted that, in this embodiment, the pressure plate 73 only slides up and down within the housing 70, preventing the pressure plate 73 from rotating along with the threaded rod 72 when the threaded rod 72 drives it, thus ensuring the downward pressure delivery of the medicine by the pressure plate 73. Furthermore, the pressure plate 73 is slidably and sealingly connected to the housing 70, and the threaded connection between the threaded rod 72 and the pressure plate 73 also has sufficient sealing, further ensuring the downward pressure delivery of the medicine by the pressure plate 73.

[0054] One-way valve 74 is connected to the bottom of housing 70.

[0055] It is understandable that the one-way valve 74 is a valve body that allows the medicine to flow in one direction, and the one-way valve 74 is a common component on the market. In addition, the one-way valve 74 is located at the bottom of the tank 70, so that the one-way valve 74 will not be opened due to the gravity of the medicine inside the tank 70, thereby ensuring that the device sprays the medicine evenly.

[0056] One end of the connecting pipe 75 is connected to the one-way valve 74, and the other end of the connecting pipe 75 is connected to the first water pipe 3. One end of the abutment 76 is connected to the pressure plate 73 and is slidably sealed to the housing 70. The other end of the abutment 76 is rotatably connected to the rotary control console 20.

[0057] In this embodiment, the abutment member 76 is used to abut the rotary control console 20 when the pressure plate 73 gradually presses down to the bottom of the housing 70, thereby gradually pushing the dosing assembly 7 to slide on the support frame 2 and away from the rotary control console 20, so that the first gear 40 and the second gear 71 gradually disengage from the transmission. When the pressure plate 73 presses down to the bottom of the housing 70, the first gear 40 and the second gear 71 completely disengage from the transmission. Thus, after the device finishes spraying, the rotation of the first gear 40 no longer controls the idling of the dosing assembly 7, reducing the number of times the dosing assembly 7 is used and the wear, and improving the service life of the dosing assembly 7 and the utilization rate of the equipment.

[0058] Specifically, in actual operation, relevant personnel start water pump 1 to deliver high-pressure water from the first water pipe 3 to the second water pipe 4, and spray it out from the spray nozzle of the second water pipe 4. The high-pressure water impacts the rocker arm assembly 5, causing the rocker arm assembly 5 to move downward and drive the connecting rod 6 to move upward. When the connecting rod 6 slides upward in the drive slide groove 200, it can control the deflection of the connecting rod 6 on the drive slide groove 200, thereby driving the rocker arm assembly 5 to rotate at a fixed angle and driving the second water pipe 4 to rotate on the first water pipe 3. Under the drive of the second water pipe 4, the first gear 40 meshes with the second gear 71 and rotates, driving the threaded rod 72 to rotate, causing the threaded rod 72 to drive the pressure plate 73 to slide downward and apply pressure to the medicine. The one-way valve 74 is opened, and a fixed amount of medicine is delivered to the high-pressure water in the first water pipe 3 through the one-way valve 74 and the connecting pipe 75, and sprayed out from the spray nozzle with the high-pressure water. Under the flow obstruction and atomization of the atomizing needle 41, the spray area is evenly sprayed and treated.

[0059] After the rocker arm assembly 5 moves downward, it gradually returns to its initial position and moves upward, thereby driving the connecting rod 6 to move downward. When the connecting rod 6 slides downward in the drive groove 200, it does not drive the connecting rod 6 to deflect, preventing the rocker arm assembly 5 from not having enough driving force when it moves upward. After one end of the rocker arm assembly 5 rotates to the high-pressure water flow, the high-pressure water flow continues to impact the rocker arm assembly 5, causing the rocker arm assembly 5 to continue to move downward, and repeating the above operation, so that the second water pipe 4 continues to rotate, and the pressure plate 73 continues to press down the medicine, so that the medicine is quantitatively delivered into the first water pipe 3 and sprayed out with the high-pressure water flow in the first water pipe 3.

[0060] When the pressure plate 73 moves downward, it drives the abutment 76 to move downward. As the pressure plate 73 gradually presses down to the bottom of the housing 70, the abutment 76 gradually comes into contact with the rotary control console 20, and the dosing assembly 7 gradually slides on the support frame 2, thereby gradually moving away from the rotary control console 20. The first gear 40 and the second gear 71 gradually disengage from the transmission. When the pressure plate 73 presses down to the bottom of the housing 70, the first gear 40 and the second gear 71 completely disengage from the transmission. Thus, after the device finishes spraying, the rotation of the first gear 40 no longer controls the idling of the dosing assembly 7, reducing the number of times the dosing assembly 7 is used and the wear, and improving the service life of the dosing assembly 7 and the utilization rate of the equipment.

[0061] In one embodiment of this application, such as Figure 1 and Figure 7 As shown, the abutment member 76 may include a control rod 760 and a telescopic abutment rod 761.

[0062] One end of the control rod 760 is connected to the pressure plate 73 and is slidably sealed to the housing 70. One end of the telescopic abutment rod 761 is rotatably connected to the control rod 760, and the other end of the telescopic abutment rod 761 is rotatably connected to the rotary control console 20.

[0063] It is understandable that by setting the telescopic abutment rod 761, when the pressure plate 73 is pressed down from the initial position, it can drive the control rod 760 to press down and control the telescopic abutment rod 761 to retract, thereby avoiding the situation where the pressure plate 73 pushes the dosing component 7 away from the rotating control console 20 when it is pressed down from the initial position, resulting in the medicine in the tank 70 not being fully discharged.

[0064] It should be noted that the telescopic abutment member 76 described in this embodiment is a telescopic sleeve, which can be set as a multi-stage telescopic sleeve as needed, so as to meet the requirement that the pressure plate 73 slides to the bottom of the box 70 inside the box 70.

[0065] In one embodiment of this application, such as Figure 2 As shown, the drive slide 200 may include a drive part 2000 and a recovery part 2001, which are connected and are arranged in a circular array on the rotary control console 20.

[0066] It should be noted that the drive part 2000 is tilted, which can drive the connecting rod 6 to deflect. The recovery part 2001 is vertically set, so as to avoid the rocker arm assembly 5 not having enough force to drive it to move downward if the recovery part 2001 is set in a tilted state.

[0067] It is understandable that the drive slide 200 is arranged in a circular array on the rotary control console 20 and connected in sequence, and there is a height difference between the recovery part 2001 and the drive part 2000, so that the connecting rod 6 slides towards the drive part 2000 after the recovery part 2001 has slid.

[0068] In one embodiment of this application, such as Figure 1 and Figure 5 and Figure 6 As shown, the rocker arm assembly 5 may include a mounting rod 50, a rocker arm bracket 51, a force plate 52, and a counterweight 53.

[0069] The mounting rod 50 is rotatably connected to the second water pipe 4, the rocker arm bracket 51 is connected to the mounting rod 50, one end of the rocker arm bracket 51 is provided with a sliding control groove 510, one end of the connecting rod 6 is slidably connected to the sliding control groove 510, the force plate 52 is inclinedly set at one end of the rocker arm bracket 51 and rotatably set at the spray nozzle of the second water pipe 4, and the counterweight 53 is connected to the other end of the rocker arm bracket 51.

[0070] Understandably, the sliding groove 510 is designed to prevent the connecting rod 6 from being unable to effectively release the bending force of the arc when the rocker arm bracket 51 moves upward or downward in an arc, thus preventing the connecting rod 6 from breaking or bending.

[0071] It is understandable that by setting the counterweight 53, the force plate 52 of the rocker arm bracket 51 is rotated to a state of impact with the high-pressure water flow, so that the force plate 52 on the rocker arm bracket 51 is impacted downward by the high-pressure water flow again.

[0072] It is understandable that the inclined setting of the force plate 52 means that the bottom of the force plate 52 is closer to the spray port of the second water pipe 4, and the top of the force plate 52 is farther away from the spray port of the second water pipe 4, thereby increasing the force-bearing area of ​​the high-pressure water flow and the force plate 52, increasing the force on the force plate 52, so that the rocker arm assembly 5 has sufficient driving force to drive the first gear 40, and make the first gear 40 mesh with and rotate the second gear 71.

[0073] It is understandable that one end of the atomizing needle 41 is set on one side of the force plate 52 to ensure the impact effect of the high-pressure water flow on the force plate 52.

[0074] In one embodiment of this application, such as Figure 5 and Figure 6 As shown, a torsion spring 501 is provided on the mounting rod 50. The torsion spring 501 is sleeved on the mounting rod 50. One end of the torsion spring 501 is connected to the rocker arm bracket 51, and the other end of the torsion spring 501 is connected to the second water pipe 4.

[0075] It is understandable that by setting the torsion spring 501, the force plate 52 of the rocker arm bracket 51 is further assisted to rotate to the state of impact with the high-pressure water flow, so that the force plate 52 on the rocker arm bracket 51 is impacted downward by the high-pressure water flow again.

[0076] Understandably, the force plate 52, impacted by the high-pressure water flow, generates a downward force greater than the initial elastic deformation torque of the torsion spring plus the driving force of the first gear 40 meshing with the second gear 71. This ensures the rocker arm bracket 51's up-and-down driving control of the connecting rod 6, guaranteeing that the medicine in the dosing assembly 7 enters the first water pipe 3. Furthermore, as the force plate 52 continues to move downward, the elastic deformation torque generated by the torsion spring 501 gradually increases, causing the force plate 52 and the rocker arm bracket 51 to gradually stop moving downward. Under the elastic deformation recovery of the torsion spring 501, the force plate 52 moves upward rapidly, causing the high-pressure water flow to impact the force plate 52 again, causing it to move downward, and repeating this cycle. This allows the medicine in the dosing assembly 7 to continuously enter the first water pipe 3. In addition, after the medicine delivery in the housing 70 of the dosing assembly 7 is completed, the overall mass of the dosing assembly 7 decreases significantly due to the outflow of medicine, thereby greatly reducing the driving force of the pressure plate 73 to drive the abutment member 76, causing the abutment member 76 to drive the second gear 71 on the housing 70 to disengage from the first gear 40.

[0077] Specifically, in actual operation, relevant personnel start water pump 1 to deliver high-pressure water from the first water pipe 3 to the second water pipe 4, and spray it out from the sprinkler nozzle of the second water pipe 4. The high-pressure water impacts the force plate 52, causing one end of the force plate 52 of the rocker arm bracket 51 to move downwards and one end of the counterweight 53 of the rocker arm bracket 51 to move upwards, which in turn drives the connecting rod 6 to move upwards. When the connecting rod 6 slides upwards in the driving part 2000 of the driving slide groove 200, the driving part 2000 can control the connecting rod 6 to deflect on the rotary control console 20. The rotation causes the rocker arm assembly 5 to rotate at a fixed angle, which in turn causes the second water pipe 4 to rotate on the first water pipe 3. Under the drive of the second water pipe 4, the first gear 40 meshes with the second gear 71 and rotates, which in turn drives the threaded rod 72 to rotate. This causes the threaded rod 72 to drive the pressure plate 73 to slide downwards and apply pressure to the medicine. The one-way valve 74 is then opened, and a fixed amount of medicine is delivered through the one-way valve 74 and the connecting pipe 75 to the high-pressure water flow in the first water pipe 3. The medicine is then sprayed out from the spray nozzle along with the high-pressure water flow. Under the flow-blocking atomization of the atomizing needle 41, the medicine is evenly sprayed and irrigated in the irrigation area.

[0078] After one end of the force plate 52 of the rocker arm bracket 51 moves downward, it gradually returns to its initial position with the assistance of the counterweight 53 and the torsion spring 501, causing one end of the force plate 52 of the rocker arm bracket 51 to move upward, thereby driving the connecting rod 6 to move downward. The connecting rod 6 slides from the driving part 2000 to the recovery part 2001. When the connecting rod 6 slides downward in the recovery part 2001, it does not drive the connecting rod 6 to deflect, preventing insufficient driving force when the rocker arm assembly 5 moves upward. After the force plate 52 rotates to the high-pressure water flow, the high-pressure water flow continues to impact the rocker arm assembly 5, causing the rocker arm assembly 5 to continue to move downward. The above operation is repeated, causing the second water pipe 4 to continue to rotate, the pressure plate 73 to continue to press down the medicine, and the medicine is quantitatively delivered into the first water pipe 3 and sprayed out with the high-pressure water flow in the first water pipe 3.

[0079] When the pressure plate 73 moves downward, it drives the control rod 760 downward and causes the telescopic abutment rod 761 to retract. As the pressure plate 73 gradually presses down to the bottom of the housing 70, the telescopic abutment rod 761 gradually comes into contact with the rotary control console 20, and the dosing assembly 7 gradually slides on the support frame 2, thus gradually moving away from the rotary control console 20. The first gear 40 and the second gear 71 gradually disengage. When the pressure plate 73 presses down to the bottom of the housing 70, the first gear 40 and the second gear 71 completely disengage. Thus, after the device finishes spraying, the rotation of the first gear 40 no longer controls the idling of the dosing assembly 7, reducing the number of times the dosing assembly 7 is used and the wear, and improving the service life of the dosing assembly 7 and the utilization rate of the equipment.

[0080] In summary, the sprinkler irrigation device of this application embodiment can realize both sprinkler irrigation and pesticide spraying functions, thereby improving the utilization rate of the device and reducing the labor intensity of relevant personnel.
