Description

Technical Field

[0001] This invention relates to the field of forest irrigation technology, and in particular to an energy-saving irrigation device for forest trees. Background Technology

[0002] With the continuous development of the forestry industry, the requirements for forest irrigation are becoming increasingly higher. Traditional irrigation methods are often extensive and waste water resources seriously. Water-saving irrigation improves the utilization rate of water resources through various technical means, such as sprinkler irrigation and micro-sprinkler irrigation. Sprinkler irrigation is a modern and efficient irrigation technology. It uses special equipment (sprinklers) to pressurize water and spray it into the air, forming fine water droplets that are evenly sprinkled on plants and the ground.

[0003] However, there are still some problems when using sprinklers for irrigation. When fine water droplets are sprayed from the sprinkler, they have a certain initial velocity (along the spray direction) and a downward velocity under the action of gravity. As a result, the fine water droplets sprayed from the sprinkler will move in the air for a period of time before falling to the ground. This causes most of the water droplets to fall on the ground in the area far from the sprinkler, while the area closer to the sprinkler receives less water, resulting in uneven spraying and low water resource utilization.

[0004] In areas far from the sprinkler heads, the ground will accumulate water due to the large amount of water sprayed. This water cannot quickly penetrate to the ground, causing it to run off along the surface (causing water loss), and some of it will evaporate, resulting in a waste of water resources.

[0005] In view of this, this application provides an energy-saving irrigation device for forest trees to solve the above problems. Summary of the Invention

[0006] This invention provides an energy-saving irrigation device for forest trees. The device uses a rotatable guide plate to guide the outward sprayed water flow, thereby directing the water flow within the corresponding area of ​​the guide plate and reducing its dwell time. This maximizes the amount of water droplets sprayed on the ground near the irrigation device and minimizes the amount of water droplets sprayed on the ground far from the irrigation device. This redistributes the outward sprayed water flow to a certain extent, ensuring that the water droplets are sprayed evenly on the ground and reducing water waste.

[0007] This application provides an energy-saving irrigation device for forest trees, including a spray cylinder with spray holes penetrating through the circumferential sidewalls of the spray cylinder, and guide plates located on both axial sides of the spray cylinder.

[0008] A rotating rod is coaxially mounted on the spray cylinder, and two guide plates are respectively mounted on one end of the rotating rod along the radial direction of the spray cylinder. The rotating rod is connected to a driving component.

[0009] Two guide vanes are connected to an adjustment component near the spray cylinder. The adjustment component is used to adjust the number of spray holes covered by the radial projection of the guide vanes along the spray cylinder.

[0010] The spray nozzle is connected to a water inlet pipe.

[0011] In this embodiment, water from the inlet pipe is sprayed outward through the spray holes on the sprinkler cylinder, achieving the effect of sprinkler irrigation of trees. Simultaneously, a drive unit rotates a guide plate around the sprinkler cylinder, guiding the water flow sprayed outward through the spray holes. Some water is blocked by the guide plate and falls onto the ground near the sprinkler cylinder, while some unblocked water falls onto the ground further away. This intervention in the outward spray improves the uniformity of coverage from near to far from the sprinkler cylinder, avoiding... To avoid situations where areas farther from the spray nozzle receive excessive water (resulting in water accumulation due to insufficient penetration below ground level) while areas closer to the spray nozzle receive insufficient water (leaving trees in those areas without adequate water), thus preventing the full and rational utilization of water resources; in this embodiment, the tilt angle of the guide plate can be adjusted via the adjustment component, thereby guiding a portion of the water flow from the spray nozzle to different areas on the ground near the spray nozzle, further improving the uniformity of water spraying on the ground surface in areas closer to the spray nozzle.

[0012] In some embodiments, the adjustment assembly includes a lifting disc coaxially disposed above the spray cylinder, and a ring is coaxially rotatably mounted on the outer side of the lifting disc;

[0013] The ring is rotatably connected to telescopic rods on both sides of its axis, and the other end of each telescopic rod is connected to a guide plate.

[0014] In the technical solution of this embodiment, during the sprinkler irrigation process, the lifting disc is controlled to move vertically, and through the cooperation between the ring and the telescopic rod, the guide plate is driven to rotate, thereby adjusting the tilt angle of the guide plate. The change in the tilt angle of the guide plate causes the movement path of the sprayed water to change when the sprayed water is blocked by the guide plate, further improving the uniformity of the amount of water sprayed on the ground surface in the area close to the sprinkler cylinder.

[0015] In some embodiments, a lifting rod is coaxially provided at the bottom of the lifting disc and the lifting rod passes through the spray cylinder from top to bottom;

[0016] One end of the lifting rod protrudes from the bottom and abuts against the lifting component, which drives the lifting disc to perform a reciprocating lifting motion in the vertical direction;

[0017] The lifting rod is vertically slidably installed at the top of the water inlet pipe.

[0018] In this embodiment, the lifting assembly drives the lifting rod to reciprocate vertically, which in turn drives the lifting disc to move. As the lifting disc moves vertically, the guide plate rotates relative to the rotating rod, thus adjusting the tilt angle of the guide plate. The tilt angle of the guide plate changes synchronously with the vertical reciprocating motion of the lifting rod. When the lifting rod moves from bottom to top, the tilt angle of the guide plate gradually increases, and vice versa. In some embodiments, the inlet pipe has a diversion pipe connected to both sides of its axial direction, and the other end of the diversion pipe is connected to the bottom of the spray cylinder. In this embodiment, the inlet pipe delivers water to the spray cylinder through the diversion pipe, and the water is finally sprayed out through the spray holes on the spray cylinder. In some embodiments, the driving component includes a driving cavity on the diversion pipe, and an impeller rotates coaxially within the driving cavity. The impeller coaxially drives a gear located outside the driving cavity.

[0019] The two gears mesh together with a gear ring, and the gear ring is coaxially connected to the rotating rod.

[0020] In this embodiment, when water flows into the diversion pipe from the inlet pipe at a certain speed and flows through the drive chamber, the rapidly moving water flow drives the impeller to rotate. The impeller drives the gear ring to rotate through a gear that rotates on the same axis. The gear ring then drives the rotating rod to rotate, thereby driving the guide plate to rotate around the spray cylinder. This adjusts the water flow sprayed on the ground surface in the area around and close to the spray cylinder, improving the coverage of the water flow in the above area, improving the uniformity of irrigation, and improving the irrigation effect.

[0021] In some embodiments, the lifting assembly includes a top plate eccentrically rotatably mounted on the top of the water inlet pipe, and the upper surface of the top plate is provided with at least two arc-shaped bosses connected end to end, and the arc-shaped bosses are arranged in a stepped manner.

[0022] The arc-shaped boss has a sloping surface at the connection between its ends. The bottom of the lifting rod abuts against the upper surface of the arc-shaped boss. An elastic element connects the lifting rod to the top of the water inlet pipe.

[0023] In the technical solution of this embodiment, as the top plate rotates, the lifting rod that abuts against the arc-shaped protrusion on the top plate and the slope between adjacent arc-shaped protrusions are used to drive the lifting rod to move vertically. The slope is used to guide the lifting rod to move between two arc-shaped protrusions at different heights.

[0024] When the lifting rod moves from the lower arc-shaped boss to the higher arc-shaped boss, the elastic element is in a stretched state. When the lifting rod moves from the higher arc-shaped boss to the lower arc-shaped boss, the lifting rod moves down quickly under the action of the elastic element. By repeating the above process, the vertical reciprocating lifting action of the lifting rod can be realized.

[0025] In some embodiments, the intermittent drive assembly includes abutment rods spaced circumferentially along the top plate, the number of abutment rods being the same as the number of arcuate bosses;

[0026] A drive rod that mates with the abutment rod is fixed at the bottom of the gear ring.

[0027] In the technical solution of this embodiment, the gear ring rotates simultaneously, driving the drive rod to rotate around the water inlet pipe axis. Since the top plate is eccentrically mounted on the top of the water inlet pipe, the top plate is intermittently rotated relative to the water inlet pipe through the cooperation between the drive rod and the abutment rod.

[0028] With the intermittent rotation of the top plate, the guide plate can be maintained at the adjusted angle for a certain period of time after each adjustment of the tilt angle. During this period of time, the guide plate rotates with the rotating rod, thereby achieving irrigation of the ground in the area close to the spray cylinder.

[0029] When the deflector plate is maintained at different tilt angles, it can cover and irrigate more ground in the area closer to the spray pipe, further improving the uniformity of surface irrigation in the area closer to the spray pipe.

[0030] In some embodiments, micropores are evenly distributed on the guide plate. In this embodiment, micropores can also be evenly distributed on the guide plate. When the water flow from the spray hole moves to the guide plate, some water will be blocked and unable to continue moving forward. Under the action of the guide plate, it will fall onto the ground surface around the spray cylinder. Some water will pass through the micropores and continue moving forward. This portion of water will lose kinetic energy during the passage through the micropores, causing its speed to decrease, and thus it will fall to the ground surface (falling in an area closer to the spray cylinder) in a short time. Simultaneously, the micropores on the guide plate reduce its weight, making it easier to rotate the two guide plates relative to the spray cylinder. In some embodiments, there are at least two water inlet pipes, with adjacent water inlet pipes spaced apart. The bottom of the water inlet pipes is connected to a water supply pipe, which is connected to a water supply unit. In this embodiment, a water supply pipe is laid in the area requiring irrigation, and an inlet pipe is connected to the water supply pipe at regular intervals. Each inlet pipe corresponds to an area to be irrigated. By setting multiple inlet pipes, the area to be irrigated can be covered. The water supply pipe is connected to a water supply unit, which delivers water to the inlet pipe through the water supply pipe, and finally sprays it outward through a spray nozzle. In some embodiments, the gear ring and the rotating rod are connected by a transmission rod, which is coaxially inserted into the lifting rod and spaced apart from it. In this embodiment, the gear ring and the rotating rod are connected by a connecting rod, and the lifting rod is coaxially inserted into the connecting rod and spaced apart from it. In this embodiment, the connecting rod is hollow to provide space for the lifting rod to pass through. The lifting rod and the connecting rod do not contact each other and do not hinder the vertical movement of the lifting rod. The beneficial effects of the above technical solution are as follows: (1) In this solution, the irrigation device guides the outward sprayed water flow by setting a rotatable guide plate, thereby guiding the sprayed water flow in the corresponding area of ​​the guide plate and reducing its stagnation time, thereby maximizing the amount of water droplets sprayed on the ground near the irrigation device area and minimizing the amount of water droplets sprayed on the ground far away from the irrigation device area, thus distributing the outward sprayed water flow over a certain length, making the water droplets sprayed evenly on the ground as much as possible, and reducing the waste of water resources. (2) The coverage of the spray hole by the guide plate in this solution can be automatically adjusted, thereby guiding the water flow sprayed from the spray hole to different areas of the ground near the irrigation device area, thereby further improving the uniformity of the sprayed water flow coverage of the area near the irrigation device, so that water resources can be fully utilized.

[0046] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 8 As will be clearly shown in the detailed description of the embodiments, the structural contents mentioned in the following embodiments are all based on the accompanying drawings.

[0049] With the continuous development of the forestry industry, the requirements for forest irrigation are becoming increasingly higher. Traditional irrigation methods are often extensive and waste water resources seriously. Water-saving irrigation improves the utilization rate of water resources through various technical means, such as sprinkler irrigation and micro-sprinkler irrigation. Sprinkler irrigation is a modern and efficient irrigation technology. It uses special equipment (sprinklers) to pressurize water and spray it into the air, forming fine water droplets that are evenly sprinkled on plants and the ground.

[0050] However, there are still some problems when using sprinklers for irrigation. When fine water droplets are sprayed from the sprinkler, they have a certain initial velocity (along the spray direction) and a downward velocity under the action of gravity. As a result, the fine water droplets sprayed from the sprinkler will move in the air for a period of time before falling to the ground. This causes most of the water droplets to fall on the ground in the area far from the sprinkler, while the area closer to the sprinkler receives less water, resulting in uneven spraying and low water resource utilization.

[0051] In areas far from the sprinkler heads, the ground will accumulate water due to the large amount of water sprayed. This water cannot quickly penetrate to the ground, causing it to run off along the surface (causing water loss), and some of it will evaporate, resulting in a waste of water resources.

[0052] Based on the above considerations, some embodiments of this application provide an energy-saving irrigation device for forest trees, see reference. Figures 1-8 ,in Figure 1 This is a schematic front view of the overall structure provided for some embodiments of this application; Figure 2 This is a schematic diagram of the overall structure provided for some embodiments of this application from another perspective; Figure 3 Provided for some embodiments of this application Figure 1 Schematic diagram of the AA section structure; Figure 4 A cross-sectional view of the diversion pipe 41, spray cylinder 10, and water inlet pipe 40 provided in some embodiments of this application; Figure 5 The figure shows a top view of the mating relationship between the top plate 54, the arc-shaped boss 55, the abutment rod 57, and the drive rod 58 provided in some embodiments of this application; the figure also shows a schematic diagram of the arrangement relationship between the top plate 54, the arc-shaped boss 55, and the slope 56 provided in some embodiments of this application. Figure 7 A schematic diagram showing the state of the guide vane 20 in one of the positions provided in some embodiments of this application; Figure 8 This is a schematic diagram showing the state of the guide plate 20 in another position according to some embodiments of this application.

[0053] In some embodiments of this application, the spray cylinder 10 is connected to a water inlet pipe 40 and spray holes 11 are evenly distributed on the circumferential sidewall of the spray cylinder 10. Guide plates 20 are located on both axial sides of the spray cylinder 10. A rotating rod 30 is coaxially mounted on the spray cylinder 10. The guide plates 20 are respectively rotatably mounted at both ends of the rotating rod 30 along the radial direction of the spray cylinder 10 (the guide plates 20 are obliquely mounted at the ends of the rotating rod 30). A driving component is used to drive the rotating rod 30 to rotate, thereby driving the two guide plates 20 to rotate around the spray cylinder 10. During the rotation of the guide plates 20 around the spray cylinder 10, a portion of the water flow sprayed from the spray holes 11 can be guided; that is, when the water flow sprays from the spray holes 11... When the rapidly moving water flow is obstructed by the guide plate 20 (on the one hand, the kinetic energy of this part of the water flow is lost, and on the other hand, the path of this part of the water flow is changed by the guide plate 20), so that part of the water flow that was originally going to fall to a distance far from the spray cylinder 10 falls to the ground near the spray cylinder 10 under the guidance of the guide plate 20. This increases the amount of water droplets sprayed on the ground near the spray cylinder 10, and avoids the situation in traditional sprinkler irrigation equipment where water is concentrated and falls on the ground far away from the sprinkler equipment while less water is sprayed on the ground near the sprinkler equipment. This improves the utilization rate of water resources and avoids waste.

[0054] In this embodiment, the tilt angle of the guide plate 20 can be adjusted by adjusting the component. Adjusting the tilt angle of the guide plate 20 can, on the one hand, adjust the amount of water flow blocked from the spray hole 11, and on the other hand, adjust the movement path of part of the water flow after being blocked by the guide plate 20. This can guide the water flow to fall on different ground surfaces in the area close to the spray cylinder 10, thereby further improving the uniformity of water spraying in the area close to the spray cylinder 10.

[0055] For example, as the tilt angle of the guide plate 20 gradually increases, the amount of water flow blocked by the guide plate 20 from the spray hole 11 gradually increases, and the degree to which the path of the water flow blocked by the guide plate 20 changes relative to the original path also gradually increases (making the position where this part of the water flow falls closer and closer to the spray cylinder 10). Note: When spraying water flow in all directions with the spray cylinder 10 as the center, the amount of water sprayed on the ground closer to the area of ​​the spray cylinder 10 will be smaller. However, when the tilt angle of the guide plate 20 gradually increases, it can better compensate for the amount of water sprayed in the above area and improve the uniformity of water spraying.

[0056] As the tilt angle of the guide plate 20 gradually decreases, the amount of obstruction of the water flow sprayed from the spray hole 11 by the guide plate 20 gradually decreases, and the degree to which the path of the water flow blocked by the guide plate 20 changes relative to the original path also gradually decreases (so that the location where this part of the water flow falls is farther and farther away from the spray cylinder 10).

[0057] That is, by continuously adjusting the tilt angle of the guide plate 20, the water volume in a certain area near the spray cylinder 10 is evenly replenished, thereby improving the overall water uniformity of the sprinkler irrigation device.

[0058] According to some embodiments of this application, reference is made to Figure 1 , Figure 2 ,in Figure 1 This is a schematic front view of the overall structure provided for some embodiments of this application. Figure 2 This is a schematic diagram of the overall structure provided for some embodiments of this application from another perspective;

[0059] In some embodiments of this application, the adjustment assembly includes a lifting disc 50 coaxially disposed above the spray cylinder 10, and a ring 51 is coaxially rotatably mounted on the outer side of the lifting disc 50.

[0060] Telescopic rods 52 are rotatably connected to both sides of the ring 51, and the other end of the telescopic rods 52 is rotatably installed on the rotating rod 30. The telescopic rods 52 include a sliding cylinder 5202 and a sliding rod 5201. The sliding cylinder 5202 is rotatably installed on the outer wall of the ring 51. The end of the sliding rod 5201 away from the ring 51 is connected to the guide plate 20 and is rotatably installed on the rotating rod 30. The sliding rod 5201 is movably connected inside the sliding cylinder 5202. When the rotating rod 30 rotates around the spray cylinder 10 under the action of the driving component, the telescopic rods 52 will synchronously drive the ring 51 to rotate relative to the lifting disc 50.

[0061] When the lifting disc 50 moves vertically from bottom to top, the tilt angle of the guide plate 20 relative to the rotating rod 30 gradually increases through the cooperation between the telescopic rod 52 and the ring 51. During this process, the slide rod 5201 slides out from inside the slide cylinder 5202.

[0062] When the lifting disc 50 moves vertically from top to bottom, the tilt angle of the guide plate 20 relative to the rotating rod 30 gradually decreases through the cooperation between the telescopic rod 52 and the ring 51. During this process, the slide rod 5201 retracts into the slide cylinder 5202.

[0063] In this embodiment, the ring 51 is designed to connect the telescopic rod 52 and the lifting disc 50, and also to allow the telescopic rod 52 to rotate.

[0064] According to some embodiments of this application, reference is made to Figure 1, Figure 4 ,in Figure 1 This is a schematic front view of the overall structure provided for some embodiments of this application. Figure 4 A cross-sectional view of the diversion pipe 41, spray cylinder 10, and water inlet pipe 40 provided in some embodiments of this application;

[0065] In some embodiments of this application, a lifting rod 53 is coaxially connected to the bottom of the lifting disc 50. One end of the lifting rod 53 extends vertically and is slidably installed at the top of the water inlet pipe 40. The other end of the lifting rod 53 abuts against a lifting assembly. The lifting assembly drives the lifting disc 50 to perform reciprocating lifting and lowering movements vertically through the lifting rod 53.

[0066] According to some embodiments of this application, reference is made to Figure 4 ,in Figure 4 A cross-sectional view of the diversion pipe 41, spray cylinder 10, and water inlet pipe 40 provided in some embodiments of this application;

[0067] In some embodiments of this application, the water inlet pipe 40 is provided with a diversion pipe 41 on both sides of the axial direction, and the other end of the diversion pipe 41 is connected to the bottom of the spray cylinder 10. Water flows from the water inlet pipe 40 into the two diversion pipes 41 and from the diversion pipes 41 into the spray cylinder 10, and finally sprays outward through the spray holes 11 provided on the circumferential side wall of the spray cylinder 10 to achieve the sprinkler irrigation effect.

[0068] According to some embodiments of this application, reference is made to Figure 3 , Figure 4 ,in Figure 3 Provided for some embodiments of this application Figure 1 Schematic diagram of the AA section structure. Figure 4 A cross-sectional view of the diversion pipe 41, spray cylinder 10, and water inlet pipe 40 provided in some embodiments of this application;

[0069] In some embodiments of this application, the driving component includes a driving cavity 60 disposed on the diversion pipe 41, and an impeller 61 is coaxially rotated in the driving cavity 60. Water flows into the driving cavity 60 from the diversion pipe 41 and causes the impeller 61 to rotate in the driving cavity 60. Then, it flows out from the other end of the driving cavity 60 and finally enters the spray cylinder 10. In this embodiment, the two impellers 61 are set to rotate in the same direction under the impact of the water flow. Each impeller 61 drives a gear 62 disposed at the bottom of the driving cavity 60. A gear ring 63 is provided between the two gears 62 and the gear ring 63 meshes with the two gears 62 respectively, thereby realizing that the gear ring 63 is driven to rotate under the action of the water flow. The gear ring 63 is coaxially connected to the rotating rod 30, and finally realizes that the rotating rod 30 is driven to rotate by the impact of the water flow, thereby realizing the effect of driving the guide plate 20 to rotate around the spray cylinder 10.

[0070] In this embodiment, no additional driving components are required to drive the guide plate 20 to rotate around the spray cylinder 10.

[0071] According to some embodiments of this application, reference is made to Figure 5 , Figure 6 ,in Figure 5 The figure shows a top view of the mating relationship between the top plate 54, the arc-shaped boss 55, the abutment rod 57, and the drive rod 58 provided in some embodiments of this application. The figure also shows a schematic diagram of the arrangement relationship between the top plate 54, the arc-shaped boss 55, and the slope 56 provided in some embodiments of this application.

[0072] In some embodiments of this application, the lifting assembly includes a top plate 54 eccentrically mounted on the top of the water inlet pipe 40. The upper surface of the top plate 54 is provided with at least two arc-shaped protrusions 55 connected end to end. In this embodiment, three arc-shaped protrusions 55 are provided as an example for description (the specific number can be adjusted according to actual needs). The multiple arc-shaped protrusions 55 are arranged in a stepped manner (the multiple arc-shaped protrusions equally divide the top plate along the circumference). A slope 56 is provided at the end-to-end connection of two adjacent arc-shaped protrusions 55. The bottom of the lifting rod 53 abuts against the upper surface of the arc-shaped protrusion 55, and an elastic element (which can be a spring or other component with elastic deformation) is connected between the lifting rod 53 and the top of the water inlet pipe 40.

[0073] The top plate 54 is connected to an intermittent drive assembly, which enables the plate to rotate a certain angle at regular intervals. This embodiment uses three arc-shaped protrusions 55 as an example. The slope 56 has two sections: slope 56c, slope 56d, and slope 56f. In this application, the intermittent drive assembly drives the top plate 54 along... Figure 5 Rotating in the direction indicated by the middle arrow, in this embodiment, two of the three slopes 56 (slopes 56c and 56d) are used to guide the lifting rod 53 from the lower arc-shaped boss 55 to the higher arc-shaped boss 55. The other slope 56f does not need to have the above effect. When the lifting rod 53 passes through the slope 56f, it moves from the arc-shaped boss 55 at the highest position to the arc-shaped boss 55 at the lowest position. Therefore, the slope 56f does not need to be set to be the same as the slopes 56c and 56d (with curvature). The slope 56f can be directly set as a vertical end face as shown in the figure (which can reduce the part processing procedures). When the lifting rod 53 moves from the arc-shaped boss 55 at the highest position to the arc-shaped boss 55 at the lowest position and passes through the slope 56f, the lifting rod 53 will quickly move down under the action of the elastic element (at this time the elastic element is in an energy storage state) and abut against the upper end face of the arc-shaped boss 55 at the lowest position.

[0074] Assuming that initially, the lifting rod 53 is at point C, after the intermittent drive assembly rotates the top plate 54 by a certain angle for the first time, the position of the lifting rod 53 changes from point C to point D. After the intermittent drive assembly rotates the top plate 54 by a certain angle for the second time, the position of the lifting rod 53 changes from point D to point F. After the intermittent drive assembly rotates the top plate 54 by a certain angle for the third time, the position of the lifting rod 53 changes from point F to point C. This completes one full rotation of the top plate 54 (the following process is the same).

[0075] When the contact point of the lifting rod 53 changes from point C to point D, the lifting rod 53 rises vertically to a certain height. When the contact point of the lifting rod 53 changes from point D to point F, the lifting rod 53 continues to rise vertically to a certain height. When the contact point of the lifting rod 53 changes from point F to point C, the lifting rod 53 descends to the initial position height. During this process, the lifting rod 53 completes a complete vertical reciprocating lifting action, thereby simultaneously driving the tilt angle of the guide plate 20 to undergo a small-large-small adjustment process.

[0076] In this embodiment, the bottom of the lifting rod 53 is rounded at the point where it abuts the arc-shaped boss 55, so that it can cooperate with the slope 56c and slope 56d during its movement from the lower arc-shaped boss 55 to the higher arc-shaped boss 55, thus making the vertical movement of the lifting rod 53 from bottom to top smoother.

[0077] According to some embodiments of this application, reference is made to Figure 5 , Figure 6 ,in Figure 5 The figure shows a top view of the mating relationship between the top plate 54, the arc-shaped boss 55, the abutment rod 57, and the drive rod 58 provided in some embodiments of this application. The figure also shows a schematic diagram of the arrangement relationship between the top plate 54, the arc-shaped boss 55, and the slope 56 provided in some embodiments of this application.

[0078] In some embodiments of this application, the intermittent drive assembly includes abutment rods 57 that are equidistantly spaced along the circumference of the top plate 54, and the number of abutment rods 57 is the same as the number of arc-shaped bosses 55.

[0079] A drive rod 58 that mates with the abutment rod 57 is fixed at the bottom of the gear ring 63. In this embodiment, the gear ring 63 is coaxially arranged with the water inlet pipe 40, and the top plate 54 is eccentrically arranged with the water inlet pipe 40. This ensures that when the gear ring 63 drives the drive rod 58 to rotate one revolution, it can only contact one of the abutment rods 57 and cause the top plate 54 to rotate a certain angle (let's call it x). Figure 5As shown, assuming that at a certain moment the contact point between the lifting rod 53 and the arc-shaped boss 55 is at position C in the figure, the driving rod 58 moves with the gear ring 63 and moves to position a. As the gear ring 63 continues to move, the driving rod 58 contacts the contact rod 57 and drives the top plate 54 to rotate synchronously. When the driving rod 58 rotates with the gear ring 63 to position b (at this time the driving rod 58 and the contact rod 57 are no longer in contact), as the gear ring 63 continues to rotate, the top plate 54 no longer rotates synchronously with the rotation of the gear ring 63 (during this process, the top plate 54 rotates by an angle x). During the rotation of the top plate 54 by an angle x, the contact point between the lifting rod 53 and the arc-shaped boss 55 changes from position C to position D, causing the lifting rod 53 to rise vertically to a certain height.

[0080] When the gear ring 63 drives the drive rod 58 to rotate to position a in the figure again, it can drive the top plate 54 to rotate again, so that the contact point between the lifting rod 53 and the arc-shaped boss 55 changes from position D to position F, so that the lifting rod 53 continues to rise vertically to a certain height.

[0081] When the gear ring 63 drives the drive rod 58 to rotate to position a in the figure for the third time, it can drive the top plate 54 to rotate again, so that the contact point between the lifting rod 53 and the arc-shaped boss 55 changes from position F to position C, so that the lifting rod 53 descends vertically to the initial position, thus completing a complete vertical reciprocating lifting action.

[0082] In some embodiments of this application, micro-holes may be evenly distributed on the guide plate 20. When the water flow sprayed from the spray hole 11 moves to the position of the guide plate 20, some of the water flow will be blocked and unable to continue moving forward. As a result, under the action of the guide plate 20, it will fall onto the ground surface in the area around the spray cylinder 10. Some of the water flow will pass through the micro-holes and continue to move forward through the guide plate 20. This part of the water flow will lose kinetic energy during the process of passing through the micro-holes, causing its speed to decrease, so that this part of the water flow will also fall to the ground surface in a short time (falling into the area closer to the spray cylinder 10).

[0083] Meanwhile, the micro-holes on the guide plate 20 also reduce the weight of the guide plate 20, making it easier to rotate the two guide plates 20 relative to the spray cylinder 10.

[0084] In some embodiments of this application, there are at least two water inlet pipes 40 and adjacent water inlet pipes 40 are spaced apart. The bottom of the water inlet pipes 40 is connected to a water supply pipe and the water supply pipe is connected to a water supply unit. The water supply pipe and the water supply unit are not shown in the figure.

[0085] Water pipes are laid in the areas that need irrigation, and water inlet pipes 40 are connected to the water pipes at certain intervals. Each water inlet pipe 40 corresponds to an area to be irrigated. By setting up multiple water inlet pipes 40, the area to be irrigated can be covered. The water pipes are connected to a water supply unit, which delivers water to the water inlet pipes 40 through the water pipes, and finally sprays it outward through the spraying cylinder 10.

[0086] According to some embodiments of this application, reference is made to Figure 4 ,in Figure 4 A cross-sectional view of the diversion pipe 41, spray cylinder 10, and water inlet pipe 40 provided in some embodiments of this application;

[0087] In some embodiments of this application, the gear ring 63 is connected to the rotating rod 30 via a connecting rod 31. The connecting rod 31 is rotatably mounted coaxially with the spray cylinder 10. The lifting rod 53 is coaxially inserted into the connecting rod 31 and spaced apart from the connecting rod 31. In this embodiment, the connecting rod 31 is hollow to provide space for the lifting rod 53 to pass through. The lifting rod 53 does not contact the connecting rod 31 and does not hinder the vertical movement of the lifting rod 53.

[0088] The above is merely for illustrating the present invention. It should be understood that the present invention is not limited to the above embodiments, and various modifications that conform to the spirit of the present invention are within the protection scope of the present invention.
