Description

Technical Field

[0001] This utility model relates to the field of greening maintenance watering technology, and in particular to a pressure-regulating greening maintenance watering device. Background Technology

[0002] With the continuous advancement of urban greening construction, the number of various green areas such as urban road green belts, parks, squares, residential courtyards and nursery bases continues to grow. The demand for plant maintenance in these areas is also increasing. Especially during dry or high-temperature seasons, timely and effective watering maintenance has become one of the key measures to ensure the normal growth of plants.

[0003] A Chinese patent has been published: a pressure-regulating greening maintenance sprinkler device, patent announcement number: CN213187517U. The patent "includes a housing mounted on a vehicle frame, a motor installed at the bottom inner part of the housing, a rotating rod keyed to the output shaft of the motor, a threaded rod on the rotating rod, a guide rod installed on the top surface of the housing, a support seat screwed to the threaded rod, the support seat sliding on the guide rod with gaps, a vertical rod fixedly mounted on the support seat, a ball seat fixedly connected to the top of the vertical rod, a ball hinged to the ball seat, and a water spray pipe fixedly connected to the ball."

[0004] Although this sprinkler system uses a T-handle to adjust the angle of the drain pipe for spraying, the manual holding and control of the nozzles, while convenient, has significant shortcomings in practical application. Because the water outlet must be continuously held and adjusted manually, the entire sprinkling process is highly dependent on the operator, resulting in high labor intensity and fatigue over extended periods. This is particularly problematic for continuous watering of large green areas, leading to low efficiency and poor stability. Furthermore, the spray angle, water distance, and water uniformity are entirely dependent on manual control, making it susceptible to uneven watering and concentrated water flow due to improper operation, which can negatively impact plant growth and overall landscaping maintenance. Therefore, this type of traditional sprinkler system, which relies heavily on manual operation, still has significant room for improvement in terms of automation and user comfort. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a pressure-regulating greening maintenance sprinkler device to solve the problem that the water outlet of the spray pipe must be held and adjusted by a person, the whole sprinkler process is highly dependent on the operator, the labor intensity is high, and long-term operation can easily cause fatigue.

[0006] To achieve the above objectives, this utility model provides a pressure-regulating greening maintenance sprinkler device, comprising a pusher plate, a push rod fixedly connected to the side wall of the pusher plate, a water tank fixedly connected to the top of the pusher plate, rotating rods rotatably connected to both sides of the bottom of the pusher plate, rotating wheels fixedly connected to both ends of the two rotating rods, support plates fixedly connected to both sides of the top of the pusher plate, a collar rod rotatably connected to the top of the support plates, a water pump fixedly connected to the side wall of the water tank, the input end of the water pump extending into the water tank, and two water pipes fixedly connected to the output end of the water pump. The two water pipes respectively pass through the collar rod and are fixedly connected to nozzles. A uniform spraying mechanism is provided between the bottom end of the collar rod and the bottom of the pusher plate to drive the nozzles to reciprocate and spray the greenery evenly. A pressure regulating mechanism is provided inside the water pipes to adjust the diameter of the inner wall of the water pipes.

[0007] Preferably, the uniform spraying mechanism includes an inner rotating rod rotatably connected to the top of the trolley plate, a rotating disk fixedly connected to the top of the inner rotating rod, a rotating column fixedly connected to the top edge of the rotating disk, a reciprocating rod rotatably connected to the top of the trolley plate, an inner sliding groove formed at the top of the reciprocating rod, the rotating column extending into the inner sliding groove, a first telescopic rod fixedly connected to one end of the reciprocating rod, a moving rod rotatably connected to one end of the first telescopic rod, a second telescopic rod rotatably connected to both ends of the moving rod, and a collar rod penetrating the inner wall of the support plate and rotatably connected to one end of the second telescopic rod.

[0008] Preferably, the bottom end of the inner rotating rod penetrates the bottom of the trolley plate, and an outer transmission cylinder is rotatably connected to the outer wall of the inner rotating rod. A first bevel gear is fixedly connected to the bottom end of the outer transmission cylinder, and a second bevel gear meshes with the outer wall of the first bevel gear. The second bevel gear is fixedly connected to the outer wall of the rotating rod. Both the inner rotating rod and the outer wall of the outer transmission cylinder are provided with internal threaded holes, and threaded plugs are internally threaded into the internal threaded holes.

[0009] Preferably, the pressure regulating mechanism includes a receiving groove fixedly connected to the outer wall of the water pipe, a flow plate fixedly connected to the inner wall of the receiving groove, a plurality of pressure regulating baffles evenly distributed at equal intervals rotatably connected to the side wall of the flow plate, a pressure regulating ring rotatably connected to the side wall of the flow plate, a pull rod rotatably connected to the side wall of each of the evenly distributed pressure regulating baffles, one end of the pull rod being rotatably connected to the side wall of the pressure regulating ring, and a flow hole being provided on the side wall of the flow plate.

[0010] Preferably, the outer wall of the storage groove is provided with a through groove, and the outer wall of the pressure regulating ring is fixedly connected with a toggle rod, the top end of the toggle rod extending out of the through groove.

[0011] Preferably, the outer wall of the pressure regulating ring is tightly fitted to the inner wall of the receiving groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. This pressure-regulating greening maintenance sprinkler system, through a mechanical linkage structure of a uniform spraying mechanism, enables the spray head to automatically reciprocate left and right while the trolley is being moved. This is achieved through the transmission action of components such as rotating wheels and rotating rods. The spray head continuously sprays water as the pump continuously supplies it, eliminating the need for manual control of the spray angle and direction. This significantly reduces the user's workload, improves the uniformity and coverage of the spraying operation, and avoids errors caused by human control. It is particularly suitable for efficient and uniform watering operations in large green areas, thus significantly improving operational comfort, automation, and greening maintenance effectiveness.

[0014] 2. This pressure-regulating greening maintenance sprinkler device, when in use, allows the user to rotate the pressure-regulating ring by moving a lever. During rotation, the ring simultaneously pulls multiple connected rods, which in turn rotate multiple pressure-regulating baffles. As the baffles rotate, they create gaps of varying sizes with the flow holes, thus adjusting the flow area of ​​the water. When the gap increases, the water flow rate increases, and the water pressure rises accordingly; when the gap decreases, the water flow is restricted, and the water pressure decreases. This allows for flexible adjustment of water pressure and spray volume, meeting the diverse needs of different greening maintenance scenarios for water pressure and spray intensity, and improving the device's adaptability and ease of use.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0025] like Figures 1 to 5 As shown, a pressure-regulating greening maintenance sprinkler device includes a pusher plate 1, a push rod 2 fixedly connected to the side wall of the pusher plate 1, a water tank 3 fixedly connected to the top of the pusher plate 1, rotating rods 4 rotatably connected to both sides of the bottom of the pusher plate 1, rotating wheels 5 fixedly connected to both ends of the two rotating rods 4, support plates 6 fixedly connected to both sides of the top of the pusher plate 1, a collar rod 7 rotatably connected to the top of the support plate 6, a water pump 8 fixedly connected to the side wall of the water tank 3, the input end of the water pump 8 extending into the water tank 3, and two water pipes 9 fixedly connected to the output end of the water pump 8. The two water pipes 9 pass through the collar rod 7 and are fixedly connected to nozzles 10. A uniform spraying mechanism is provided between the bottom end of the collar rod 7 and the bottom of the pusher plate 1 to drive the nozzles 10 to move and spray the green plants evenly. A pressure regulating mechanism is provided inside the water pipes 9 to adjust the inner diameter of the water pipes 9.

[0026] Further, see attached document. Figure 2 and Figure 3 As shown, the uniform spraying mechanism includes an inner rotating rod 11 rotatably connected to the top of the trolley plate 1. A rotating disk 12 is fixedly connected to the top of the inner rotating rod 11. A rotating column 13 is fixedly connected to the top edge of the rotating disk 12. A reciprocating rod 14 is rotatably connected to the top of the trolley plate 1. An inner sliding groove 15 is formed on the top of the reciprocating rod 14. The rotating column 13 extends into the inner sliding groove 15. A first telescopic rod 16 is fixedly connected to one end of the reciprocating rod 14. A moving rod 17 is rotatably connected to one end of the first telescopic rod 16. A second telescopic rod is rotatably connected to both ends of the moving rod 17. 18. The bottom end of the collar rod 7 passes through the inner wall of the support plate 6 and is rotatably connected to one end of the second telescopic rod 18. The bottom end of the inner rotating rod 11 passes through the bottom of the trolley plate 1. The outer wall of the inner rotating rod 11 is rotatably connected to the outer transmission cylinder 19. The bottom end of the outer transmission cylinder 19 is fixedly connected to the first bevel gear 20. The outer wall of the first bevel gear 20 is meshed with the second bevel gear 21. The second bevel gear 21 is fixedly connected to the outer wall of the rotating rod 4. The outer walls of the inner rotating rod 11 and the outer transmission cylinder 19 are both provided with internal threaded holes 22. The internal threaded holes 22 are internally threaded with threaded plugs 23.

[0027] When the uniform spraying mechanism is in use, first turn on the power and start the water pump 8. The water pump 8 starts to draw water from the water tank 3 and delivers the water to the nozzle 10 through the water pipe 9 to achieve continuous water supply and spraying.

[0028] Subsequently, the user pushes the cart plate 1 along the ground using the push rod 2. At this time, the rotating wheel 5 located below the cart plate 1 generates rotational force as it rolls on the ground, which in turn drives the rotating rod 4 connected to it to rotate. The rotation of the rotating rod 4 drives the second bevel gear 21 to rotate, and through the bevel gear meshing transmission, it drives the first bevel gear 20 to rotate synchronously, thereby driving the outer transmission cylinder 19 fixed on it to rotate. When the threaded plug 23 is threaded into the internal threaded hole 22 provided in the outer transmission cylinder 19 and the inner rotating rod 11, the rotation of the outer transmission cylinder 19 can synchronously drive the inner rotating rod 11 to rotate, so that the internal uniform spraying mechanism operates accordingly. If the device needs to be moved after spraying, simply remove the threaded plug 23 to disconnect the transmission connection between the outer transmission cylinder 19 and the inner rotating rod 11, so as to prevent the nozzle 10 from continuing to swing due to the rotation of the rotating wheel 5.

[0029] During rotation, the inner rotating rod 11 drives the rotating disk 12 at its end to rotate. The rotating disk 12 then drives the connected rotating column 13 to perform circular motion. The rotating column 13 slides along the inner sliding groove 15 during circular motion, thereby driving the connected reciprocating rod 14 to achieve stable reciprocating motion. The reciprocating motion of the reciprocating rod 14 causes the first telescopic rod 16 to be stretched while rotating, which in turn drives the moving rod 17 to move back and forth in the left and right directions. The moving rod 17 then drives the second telescopic rod 18 to perform synchronous stretching and rotation. The second telescopic rod 18 finally drives the collar rod 7 to swing back and forth, driving the water pipe 9 to move synchronously in the same direction, thereby driving the nozzle 10 connected to the end of the water pipe 9 to achieve reciprocating rotation, expanding the spray coverage area, improving the spray uniformity, effectively solving the problems of uneven spraying and concentrated water flow caused by unstable manual holding of traditional spraying devices, and significantly improving the efficiency of watering operations.

[0030] Through the mechanical linkage structure of the uniform spraying mechanism, while pushing the trolley plate 1 to move, the rotating wheel 5 and rotating rod 4 drive the nozzle 10 to automatically rotate left and right. The nozzle 10 sprays continuously as the water pump 8 continuously supplies water, eliminating the need for manual control of the spraying angle and direction. This significantly reduces the user's workload, improves the uniformity and coverage of the spraying operation, and avoids errors caused by human control. It is especially suitable for efficient and uniform watering operations in large green areas, thus significantly improving work comfort, automation, and green maintenance effects.

[0031] Further, see attached document. Figure 4 and Figure 5 As shown, the pressure regulating mechanism includes a receiving groove 24 fixedly connected to the outer wall of the water pipe 9. A flow plate 25 is fixedly connected to the inner wall of the receiving groove 24. Multiple pressure regulating baffles 26 evenly distributed at equal intervals are rotatably connected to the side wall of the flow plate 25. A pressure regulating ring 27 is rotatably connected to the side wall of the flow plate 25. A pull rod 28 is rotatably connected to the side wall of each of the evenly distributed pressure regulating baffles 26. One end of the pull rod 28 is rotatably connected to the side wall of the pressure regulating ring 27. A flow hole 29 is opened on the side wall of the flow plate 25. A through groove 30 is opened on the outer wall of the receiving groove 24. An actuating rod 31 is fixedly connected to the outer wall of the pressure regulating ring 27. The top end of the actuating rod 31 extends out of the through groove 30.

[0032] When the pressure regulating mechanism is in use, the user moves the lever 31 to rotate the pressure regulating ring 27. During the rotation, the pressure regulating ring 27 synchronously pulls the connected multiple levers 28, which in turn drives the multiple pressure regulating baffles 26 to rotate synchronously. As the pressure regulating baffles 26 rotate, they form gaps of different sizes with the flow holes 29, thereby adjusting the flow area of ​​water flowing through the flow holes 29. When the gap increases, the water flow rate increases and the water pressure increases accordingly; when the gap decreases, the water flow is restricted and the water pressure decreases. This achieves flexible adjustment of water pressure and spray volume, meeting the diverse needs of different greening maintenance scenarios for water pressure and spray intensity, and improving the adaptability and ease of use of the device.

[0033] Further, see attached document. Figure 5 As shown, the outer wall of the pressure regulating ring 27 is tightly attached to the inner wall of the storage groove 24. The tight attachment of the pressure regulating ring 27 to the storage groove 24 increases the damping sensation when the pressure regulating ring 27 rotates, and can limit the adjustment of the pressure regulating baffle 26.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
