DETAILED DESCRIPTION

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The utility model provides a water sprinkler 100, which can adjust the spraying range of a sprinkler head 31 by rotating a water spray pipe 30, thereby improving operation efficiency.

[0027] Reference Figures 1 to 3 According to the sprinkler truck 100 in the embodiment of the utility model, the sprinkler truck 100 includes a vehicle body 10, a water pump 20, a water spray pipe 30 and a spray head 31.

[0028] Among them, the vehicle body 10 includes a chassis 11 and a water tank 12 arranged on the chassis 11, a water pump 20 is connected to the water tank 12, a water spray pipe 30 is connected to the water pump 20, the water spray pipe 30 can rotate around its own axis, a nozzle 31 is connected to the water spray pipe 30, and rotates with the water spray pipe 30 to adjust the spraying range of the nozzle 31 in the width direction of the sprinkler truck 100; with this arrangement, the spraying range of the nozzle 31 can be adjusted by rotating the water spray pipe 30, thereby improving the operating efficiency of the sprinkler truck 100.

[0029] Specifically, when the watering truck 100 is working, the watering truck 100 can travel along the length direction, and the nozzle 31 on the watering pipe 30 can spray water toward the green belt area; wherein, the water tank 12 can be used to store clean water, and the water pump 20 is connected to the water tank 12 and the watering pipe 30 respectively to drive the clean water in the water tank 12 to flow to the watering pipe 30, and spray it through the nozzle 31 on the watering pipe 30, so as to realize the watering of the green belt and other areas by the watering truck 100. In this process, the watering pipe 30 can be rotated to change the spraying range of the nozzle 31 in the width direction, so as to facilitate the clean water sprayed by the nozzle 31 to irrigate the green belt and other areas. wherein, the rotation of the watering pipe 30 can be manually driven by the operator, or the rotation of the watering pipe 30 can be driven by setting a driving member 40.

[0030] In addition, the water spray pipe 30 can have various forms; for example, the water spray pipe 30 can extend in a straight direction, and its axis also extends in a straight direction, and the water spray pipe 30 can rotate around the axis; for another example, the water spray pipe 30 can be an arc-shaped pipe, that is, the axis of the water spray pipe 30 is an arc, so that the water spray pipe 30 can rotate with the tangent of the arc as the central axis.

[0031] It should be noted that the length direction of the sprinkler truck 100 refers to the front-to-back direction of the sprinkler truck 100 , and the width direction of the sprinkler truck 100 refers to the left-to-right direction of the sprinkler truck 100 , that is, the width direction of the sprinkler truck 100 is perpendicular to the length direction of the sprinkler truck 100 .

[0032] Therefore, according to the sprinkler truck 100 in the embodiment of the utility model, the spraying range of the sprinkler head 31 can be adjusted by rotating the water spray pipe 30, thereby improving the operation efficiency.

[0033] Of course, there are various ways to set up the water spray pipe 30 according to actual conditions. For example, the water spray pipe 30 can extend along the length direction of the sprinkler truck 100, and the spraying range can be adjusted by rotating the nozzle 31; for another example, the water spray pipe 30 can extend vertically along the length direction of the sprinkler truck 100, and the spraying range can be adjusted by rotating the nozzle 31.

[0034] According to the above, refer to Figures 1 to 3 In some embodiments of the utility model, the water spray pipe 30 extends along the length direction of the sprinkler truck 100, and the nozzle 31 rotates along with the water spray pipe 30 to adjust the pitch angle of the spraying direction of the nozzle 31; in this way, the spraying range of the nozzle 31 in the width direction of the sprinkler truck 100 can be adjusted to improve the operating efficiency of the sprinkler truck 100.

[0035] Specifically, when the sprinkler truck 100 is operating, the sprinkler truck 100 can move forward in the length direction. At this time, the water spray pipe 30 can spray water to the outside of the sprinkler truck 100 through the nozzle 31 to irrigate the green belt; wherein, the water spray pipe 30 extends along the length direction of the sprinkler truck 100. When it is necessary to adjust the spraying range of the nozzle 31, the water spray pipe 30 can be rotated to change the angle between the spraying direction of the nozzle 31 and the road surface, thereby changing the spraying range of the nozzle 31 in the width direction of the sprinkler truck 100, so as to facilitate the sprinkler truck 100 to irrigate green belts and other areas and improve operation efficiency.

[0036] Reference Figures 1 to 3 In some embodiments of the utility model, a water spray pipe 30 is arranged on the water tank 12, the water tank 12 and the water spray pipe 30 extend in the same direction, and a water spray pipe 30 is provided at least at one of the opposite sides of the water tank 12; such an arrangement can facilitate the operation of the sprinkler truck 100 and realize the irrigation function of the sprinkler truck 100.

[0037] Specifically, when the watering truck 100 is operating, the watering truck 100 can travel on a road, and there are green belts and other areas on both sides of the road. By setting the watering pipes 30 on the opposite sides of the water tank 12, the watering truck 100 can be convenient for watering the green belts and other areas on both sides of the road, thereby improving the operation efficiency. According to actual conditions, the watering pipe 30 can be set on at least one of the two opposite sides of the water tank 12 to achieve the purpose of watering.

[0038] In addition, the water spray pipe 30 extends in the same direction as the water tank 12. When the water spray pipe 30 is arranged on the side of the water tank 12, compared with the case where the water spray pipe 30 is arranged on the top of the water tank 12, the adjustment range of the angle between the spraying direction of the sprinkler head 31 and the road surface can be increased, thereby improving the irrigation coverage area. Specifically, when the water spray pipe 30 is arranged on the top of the water tank 12, due to the structural limitation of the top of the water tank 12, the spraying range of the sprinkler head 31 can be switched between spraying upward and spraying sideways, and when the water spray pipe 30 is arranged on the side of the water tank 12, the spraying range of the sprinkler head 31 can be switched between spraying upward and spraying downward, that is, it has a larger adjustable spraying range.

[0039] Reference Figure 5 In some embodiments of the utility model, the water spray pipe 30 is arranged in the up-down direction, and the nozzle 31 rotates with the water spray pipe 30 to adjust the spray direction angle of the nozzle 31 relative to the length direction of the sprinkler truck 100, as well as the spraying range in the width direction of the sprinkler truck 100; in this way, the spraying range of the nozzle 31 in the width direction of the sprinkler truck 100 can be adjusted to improve the operating efficiency of the sprinkler truck 100.

[0040] Specifically, when the sprinkler truck 100 is operating, the sprinkler truck 100 can move forward in the length direction. At this time, the water spray pipe 30 can spray water to the outside of the sprinkler truck 100 through the nozzle 31 to irrigate the green belt; wherein, the water spray pipe 30 extends along the up and down directions of the sprinkler truck 100. When it is necessary to adjust the spraying range of the nozzle 31, the water spray pipe 30 can be rotated to change the angle between the spraying direction of the nozzle 31 and the length direction, thereby changing the spraying range of the nozzle 31 in the width direction of the sprinkler truck 100, so as to facilitate the sprinkler truck 100 to irrigate green belts and other areas and improve operation efficiency.

[0041] Reference Figures 1 to 3 In some embodiments of the present invention, the sprinkler truck 100 further includes a driving member 40 , which is disposed on the vehicle body 10 and is transmission-connected to the water spray pipe 30 to drive the water spray pipe 30 to rotate, thereby improving the operating efficiency of the sprinkler truck 100 .

[0042] In combination with the above-mentioned embodiments, when the sprinkler truck 100 is operating, the water spray pipe 30 extends in the length direction, and the driving member 40 can drive the water spray pipe 30 to rotate around its own axis to change the pitch angle of the spray direction of the nozzle 31, so that the water sprayed by the nozzle 31 can be sprayed to a farther or closer position, that is, the spraying range of the nozzle 31 in the width direction of the sprinkler truck 100 can be changed, which is convenient for the sprinkler truck 100 to irrigate green belts and other areas, and improve the operation efficiency. Compared with the method of manually driving the water spray pipe 30 to rotate by the operator, driving the water spray pipe 30 to rotate by the driving member 40 can improve the operation efficiency of the sprinkler truck 100.

In this way, the water spray pipe 30 can be driven to rotate around its own axis by the driving member 40, so as to realize the adjustment of the spraying range of the sprinkler truck 100 and improve the working efficiency.

[0044] Among them, combined with the above-mentioned embodiments, when the axis of the water spray pipe 30 extends in a straight direction, the central axis of rotation of the water spray pipe 30 can be the axis of the water spray pipe 30; when the water spray pipe 30 is arc-shaped, the axis of the water spray pipe 30 is an arc line, and at this time the tangent of the arc line can be the central axis of rotation of the water spray pipe 30.

[0045] Optionally, the axis of the water spray pipe 30 is a straight line; the connecting arm 32 can extend vertically along the axis of the water spray pipe 30, one end of the connecting arm 32 is fixedly connected to the water spray pipe 30, and the other end is hinged to the other end of the driving member 40, that is, the hinge point between the driving member 40 and the connecting arm 32 deviates from the rotation center axis of the water spray pipe 30. At this time, the driving member 40 can drive the other end of the connecting arm 32 to rotate around the rotation center axis of the water spray pipe 30 through a telescopic drive, so that the water spray pipe 30 fixedly connected to the connecting arm 32 can also rotate around the rotation center axis, thereby realizing the pitch angle adjustment of the spraying direction of the sprinkler 31, so as to change the spraying range of the sprinkler truck 100, cover the green belt that needs to be irrigated, and improve the working efficiency.

[0046] Reference Figures 1 to 3 In some embodiments of the utility model, the water spray pipe 30 is rotatably disposed on the water tank 12 around its own axis; specifically, the water spray pipe 30 can be disposed on the water tank 12 to reduce the complexity of the pipeline of the sprinkler truck 100, and the water tank 12 can simply transport water to the water spray pipe 30 to achieve irrigation, and the water spray pipe 30 can be rotatably connected to the water tank 12, that is, the spraying range of the sprinkler truck 100 in the width direction can be adjusted by the self-rotation of the water spray pipe 30.

[0047] Reference Figures 1 to 3In some embodiments of the utility model, a fixing seat 121 is provided on the vehicle body 10, and the fixing seat 121 is arranged on the vehicle body 10 along the extension direction of the water spray pipe 30. A fixing hole is provided on the fixing seat 121 for the water spray pipe 30 to pass through so as to be sleeved in the fixing seat 121 and rotatable; in this way, through the cooperation between the fixing seat 121 and the water spray pipe 30, the self-rotation of the water spray pipe 30 can be realized to adjust the spraying range of the sprinkler truck 100.

[0048] In detail, in combination with the aforementioned embodiments, the vehicle body 10 may include a chassis 11 and a water tank 12, the water tank 12 is arranged on the chassis 11, the water spray pipe 30 may be arranged on the water tank 12, and a fixing seat 121 is arranged on the water tank 12, the water spray pipe 30 may be sleeved in the fixing hole of the fixing seat 121, and may rotate relatively, and the water spray pipe 30 may be stably rotated through the fixing seat 121 to adjust the spraying range of the sprinkler truck 100.

[0049] Further, in combination with the aforementioned embodiment, the water spray pipe 30 can extend along the length direction of the sprinkler truck 100, and the fixing seat 121 can include multiple, and the multiple fixing seats 121 can be arranged on the water tank 12 along the length direction of the sprinkler truck 100, so the water spray pipe 30 can be respectively sleeved in the multiple fixing seats 121 and can rotate, which can further improve the stability of the water spray pipe 30 arranged on the water tank 12; during operation, through the drive of the driving member 40, the water spray pipe 30 can rotate relative to the multiple fixing seats 121 to adjust the spraying range of the sprinkler truck 100.

[0050] Reference Figures 1 to 3 In some embodiments of the utility model, a plurality of nozzles 31 are connected to the water spray pipe 30, and the plurality of nozzles 31 are arranged on the water spray pipe 30 along the extension direction of the water spray pipe 30; optionally, in combination with the aforementioned embodiment, the water spray pipe 30 extends along the length direction of the sprinkler truck 100, and the water tank 12 extends in the same direction as the water spray pipe 30. By arranging the plurality of nozzles 31 along the extension direction of the water spray pipe 30, the spraying range of the sprinkler truck 100 can be increased, thereby improving the operating efficiency.

[0051] Reference Figure 1 and Figure 2 In some embodiments of the utility model, the sprinkler truck 100 also includes a connecting pipe 122 and a hose 50. The connecting pipe 122 is connected to the water pump 20, and can guide the water flow output by the water pump 20 to flow to the water spray pipe 30. The hose 50 is respectively connected to the connecting pipe 122 and the water spray pipe 30; in this way, the water flow output by the water pump 20 can be transported to the water spray pipe 30 through the connecting pipe 122, thereby realizing the spraying function of the sprinkler truck 100, and the rotation stability of the water spray pipe 30 can be guaranteed through the flexibility of the hose 50.

[0052] Furthermore, a plurality of water spray pipes 30 may be connected to the water tank 12, and the water pump 20 may drive the water flow in the water tank 12 to flow toward the connecting pipe 122. The connecting pipe 122 has a plurality of outlets, and the plurality of outlets correspond to and are connected to a plurality of water spray pipes 30, respectively. Through the diversion effect of the connecting pipe 122, the water flow output by the water pump 20 may be guided to flow toward the plurality of water spray pipes 30, respectively, to ensure the normal water supply of the plurality of water spray pipes 30, so that the sprinkler truck 100 may irrigate green belts and other areas through the plurality of water spray pipes 30.

[0053] Correspondingly, a hose 50 can be connected between the connecting pipe 122 and the multiple water spray pipes 30 to improve the rotation stability of the water spray pipes 30; specifically, the two ends of the hose 50 are respectively connected to the connecting pipe 122 and the water spray pipes 30. When the water spray pipes 30 rotate relative to the water tank 12, due to the flexibility of the hose 50 itself, the hose 50 can be twisted to adapt to the rotation of the water spray pipes 30, thereby facilitating the sprinkler truck 100 to adjust the spraying range.

[0054] Reference Figure 4 In some embodiments of the present invention, the sprinkler truck 100 also includes a friction power take-off 60, which is respectively connected to the chassis 11 and the water pump 20 and is configured to drive the water pump 20 to work, thereby improving the operating efficiency of the sprinkler truck 100.

[0055] In general, the friction-type power take-off may include a cylinder, an inner friction plate, an outer friction plate, a driving gear, a driven gear, an output shaft and an input shaft. The input shaft may be transmission-connected to the gearbox of the chassis 11, and a driving gear is arranged on the input shaft, the output shaft may be transmission-connected to the water pump 20, and an inner friction plate is fixedly arranged on the output shaft, the outer friction plate may be fixedly connected to the driven gear and rotatably arranged on the output shaft, and the driving gear is meshed with the driven gear; under the control of the cylinder, the inner friction plate may be driven to be transmission-connected to the outer friction plate, so that the driven gear is transmission-connected to the output shaft, and the power of the chassis 11 is transmitted to the water pump 20, so that the water pump 20 can drive the water flow in the water tank 12 to flow to the water spray pipe 30, so as to realize the spraying of the sprinkler truck 100.

[0056] According to the above, when the sprinkler truck 100 is traveling, the cylinder can control the connection and separation of the inner friction plate and the outer friction plate to take power from the chassis 11. Compared with the power take-off controlled by the clutch, the present solution adopts a friction power take-off 60, which can be used without stopping and shifting gears, thereby improving working efficiency.

[0057] Reference Figure 4 In some embodiments of the utility model, a variable piston pump 70, a proportional valve 80 and a water pump motor 90 are sequentially connected between the friction power take-off 60 and the water pump 20; thus, the spraying water volume can be adjusted by controlling the proportional valve 80 to improve the working efficiency.

[0058] In the related art, the power take-off is respectively connected to the chassis 11 and the water pump 20 in transmission. During operation, the amount of water sprayed by the water pump 20 is affected by the engine speed in the chassis 11 and cannot be accurately adjusted, thus affecting the operating efficiency. Therefore, through some embodiments of the utility model, precise adjustment of the amount of water sprayed can be achieved; specifically, the friction power take-off 60 is respectively connected to the chassis 11 and the variable piston pump 70, and the power of the chassis 11 is transmitted to the variable piston pump 70. The variable piston pump 70 can drive the hydraulic oil to flow when working, that is, convert mechanical energy into pressure energy, and then the hydraulic oil can flow to the proportional valve 80 and the water pump motor 90 in sequence. The water pump motor 90 can be connected to the water pump 20 to transmit power to the water pump 20, that is, convert pressure energy into mechanical energy, so that the water pump 20 can work to drive the water flow in the water tank 12 to flow to the water spray pipe 30 to achieve spraying; wherein, the operator can control the displacement of the variable piston pump 70 by controlling the proportional valve 80, thereby controlling the flow rate of water driven by the water pump 20, and realizing the adjustment of the amount of water sprayed by the sprinkler truck 100, which is convenient for the operation of the sprinkler truck 100.

[0059] In some specific examples of the present invention, the proportional valve 80 can transmit signals to the controller in the cab of the sprinkler truck 100, so that the operator can adjust the amount of water sprayed in the cab and improve the working efficiency.

[0060] In some specific examples of the present invention, the sprinkler truck 100 may include components such as a chassis 11, a power take-off, and a hydraulic system. The water pump 20 obtains power from the power take-off on the side of the gearbox of the chassis 11, and the power take-off is a friction power take-off 60. During operation, separation and combination can be controlled by pneumatic or hydraulic means. The output end of the power take-off is connected to a variable piston pump 70, and the start and stop and speed of the water pump motor 90 are controlled by a proportional valve 80. Then, the water pump motor 90 transmits power to the water pump 20 and ensures that the speed of the water pump 20 is constant. Among them, the operator controls the speed of the water pump motor 90 through the proportional valve 80, thereby achieving precise control of the amount of water for spraying and irrigation.

[0061] In some specific examples of the present utility model, the watering truck 100 may include a chassis 11 and a water tank 12. A connecting pipe 122 is provided at the rear of the chassis 11. The water pump 20 is connected to the connecting pipe 122 and the water tank 12, respectively. A fixing seat 121 is provided on the left and right sides of the upper part of the water tank 12. The water spray pipe 30 includes a left water spray pipe and a right water spray pipe. The left water spray pipe is arranged on the left side of the water tank 12, and the right water spray pipe is arranged on the right side of the water tank 12. The left water spray pipe and the right water spray pipe are rotatably connected to the corresponding fixing seat 121.

Each spray head 31 is provided with a ball valve for controlling the opening and closing of the spray head 31, which is convenient for the operator to adjust the spray range in the width direction. A pneumatic shut-off valve is provided at the water inlet of the rear part, which is convenient for the operator to open and close the left water spray pipe and the right water spray pipe as a whole. The left water spray pipe and the right water spray pipe are connected to the connecting pipe 122 through a hose 50, which is convenient for the rotation of the water spray pipe 30. One end of the cylinder is hinged to the water tank 12, and the other end is hinged to the water spray pipe 30.
