All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0024] The present utility model provides a full-hydraulic sprinkler atomization system as Figure 1-6 shown, which includes a sprinkler truck frame 1. A water tank 2 is fixedly arranged above the sprinkler truck frame 1. A fog cannon 3 is arranged at one end of the water tank 2.

The output shaft of the hydraulic motor 6 is fixedly provided with a high-pressure water pump corresponding to the fog cannon 3.
[0025] Specifically, an engine 7 is fixedly arranged inside the sprinkler truck frame 1. The output end of the engine 7 is fixedly provided with a gear pump 8. A hydraulic oil tank 9 is arranged on one side of the gear pump 8. A multi-way directional control valve 10 is arranged on one side of the hydraulic oil tank 9. Oil guide pipes are arranged between the hydraulic motor 6, the gear pump 8, the hydraulic oil tank 9, the multi-way directional control valve 10, the hydraulic slewing reducer 4 and the lifting oil cylinder 5. The input end of the gear pump 8 is connected to the output end of the hydraulic oil tank 9.
[0026] More specifically, the multi-way directional control valve 10 includes a valve body 11 and an oil return tank 12. The oil return tank 12 is fixedly arranged at the bottom end of the valve body 11. An oil inlet tank 13 is fixedly arranged at one end of the valve body 11. An oil inlet pipe 14 is fixedly arranged in the middle of the oil inlet tank 13. The oil inlet pipe 14 is connected to the output end of the gear pump 8. An oil return pipe 15 is fixedly arranged in the middle of the oil return tank 12. The oil return pipe 15 is connected to the input end of the hydraulic oil tank 9. A communication pipe 16 is fixedly arranged between the oil inlet tank 13 and the oil return tank 12. The arrangement of the communication pipe 16 enables the hydraulic oil to directly flow back into the hydraulic oil tank 9 when the pressure is too high, so as to avoid damage to the hydraulic pipeline due to excessive pressure.
[0027] Furthermore, three oil return nozzles 17 are fixedly arranged at one end of the oil return tank 12. Check valves 18 are fixedly arranged in the middle of the three oil return nozzles 17. The arrangement of the check valves 18 can ensure the control effect of the hydraulic oil flowing through the hydraulic slewing reducer 4 and the lifting oil cylinder 5. The three oil return nozzles 17 are respectively connected to the output ends of the hydraulic motor 6, the hydraulic slewing reducer 4 and the lifting oil cylinder 5. Three channels 19 are penetrated through the middle of the valve body 11. One ends of the three channels 19 all extend into the interior of the oil inlet tank 13.

The plug rod 26 can drive the driving gear 25 to slide up and down, so that the meshing state between the driving gear 25 and the two transmission gears 24 is adjusted. Furthermore, the individual adjustment or simultaneous adjustment of the two spherical blocks 21 can be realized, so as to achieve the effect of controlling the hydraulic slewing reducer 4 and the lifting cylinder 5.
[0029] Working principle of the utility model:
[0030] When the device is in use, the engine 7 inside the sprinkler truck frame 1 drives the gear pump 8 to rotate. The gear pump 8 drives the hydraulic oil in the hydraulic pipeline to move, so that the hydraulic oil in the hydraulic oil tank 9 is pumped to the multi-way directional control valve 10. The hydraulic oil in the multi-way directional control valve 10 drives the hydraulic motor 6, the hydraulic slewing reducer 4 and the lifting cylinder 5 to work through the hydraulic pipeline respectively. The hydraulic motor 6 can drive the high-pressure water pump. The high-pressure water pump can pump the water in the water tank 2 and transport it to the fog cannon 3. The fog cannon 3 can atomize and spray the water. At the same time, the hydraulic slewing reducer 4 can drive the fog cannon 3 to rotate to adjust the horizontal angle of the fog cannon 3. The lifting cylinder 5 can drive the fog cannon 3 to turn up and down to adjust the vertical angle of the fog cannon 3, so as to adjust the working range of the fog cannon 3.
[0031] When the hydraulic oil passes through the multi-way directional control valve 10, the hydraulic oil enters the inlet oil tank 13 through the inlet oil pipe 14 under the action of the gear pump 8, and then enters the three channels 19. The hydraulic oil in the three channels 19 reaches the hydraulic motor 6, the hydraulic slewing reducer 4 and the lifting cylinder 5 respectively through the hydraulic pipeline, and then flows back to the return oil tank 12 through the hydraulic pipeline and returns to the hydraulic oil tank 9 through the return oil pipe 15 and the hydraulic pipeline. During this process, the normal flow of the hydraulic oil is always maintained in the channel 19 corresponding to the hydraulic motor 6, so as to ensure the stable operation of the high-pressure water pump. By adjusting the up and down positions of the plug rod 26 and the driving gear 25, the meshing condition between the driving gear 25 and the two transmission gears 24 is adjusted, and the control of the hydraulic oil flow rate in the channels 19 corresponding to the hydraulic slewing reducer 4 and the lifting cylinder 5 can be realized, so as to control the working state of the hydraulic slewing reducer 4 and the lifting cylinder 5.
[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
