[0027] The following is a detailed description of a hand-push sprayer truck according to the present invention, with reference to the accompanying drawings.

[0028] Combined with appendix Figure 1-6 The specific implementation process of this utility model of a hand-push sprayer is as follows:

[0029] A hand-push sprinkler truck includes a telescopic frame, wheels 1, a hose reel, and a sprinkler system. Wheels 1 are rotatably connected to the lower end of the telescopic frame for easy pushing and steering. The hose reel is rotatably connected to both sides of the telescopic frame via a pivot 2. One end of the pivot 2 has a flywheel 3, and one side of each wheel 1 has a sprocket 4 coaxially connected to it. The flywheel 3 and sprocket 4 are connected by a chain 5. The movement of the wheels 1 drives the sprocket 4 to rotate, which in turn drives the flywheel 3 via the chain 5, achieving automatic hose release. When the wheels 1 rotate in the opposite direction, the hose is wound up. The sprinkler system is detachably connected to the upper part of the telescopic frame for easy replacement and maintenance. Furthermore, the upper part of the telescopic frame also has a detachably connected push handle 6 for user operation.

[0030] The telescopic frame includes a crossbeam 7 and uprights 8 connected to both sides of the crossbeam 7. The end of the crossbeam 7 has a first sleeve 9 that fits over it and is slidably connected to it. The crossbeam 7 has several beam holes 10 evenly arranged along its extension direction. The first sleeve 9 has a first limiting hole 11, which is fixed to the beam holes 10 on the crossbeam 7 by screws. The uprights 8 have a second sleeve 12 that fits over it and is slidably connected to it. The second sleeve 12 is fixed to the bottom of the first sleeve 9. The uprights 8 have several pipe holes 13 evenly arranged along its extension direction. The second sleeve 12 has a second limiting hole 14, which is fixed to the pipe holes 13 on the uprights 8 by screws. The width of the telescopic frame can be adjusted by adjusting the position of the first sleeve. The height of the telescopic frame can be adjusted by adjusting the position of the second sleeve.

[0031] A third sleeve 15 is provided in the middle of the crossbeam 7 and is slidably connected to it. The third sleeve 15 is fixedly connected to the sprinkler device. The third sleeve 15 is provided with a third limiting hole 16. The third limiting hole 16 is fixed to the beam hole 10 by screws. The position of the third sleeve 15 on the crossbeam 7 can be adjusted to realize the adjustment of the position of the sprinkler device.

[0032] The push handle 6 has several handle holes 17 evenly arranged along its extension direction. The rear of the push handle 6 has a fourth sleeve 18 that is fitted over it and slidably connected to it. The fourth sleeve 18 has a fourth limiting hole 19, which is fixed to the handle holes 17 by screws. At the same time, the crossbeam 7 also has a fifth sleeve 20 that is fitted over it and slidably connected to it. The fifth sleeve 20 is fixed to the bottom of the fourth sleeve 18 and is located between the first sleeve 9 and the third sleeve 15. The fifth sleeve 20 has a fifth limiting hole 21, which is fixed to the beam hole 10 by screws. By adjusting the position of the fourth sleeve 18 on the push handle 6, the length of the push handle 6 can be changed. At the same time, by adjusting the position of the fifth sleeve 20 on the crossbeam 7, the width between the two push handles 6 can be adjusted.

[0033] The hose reel includes a central shaft 22, auxiliary rods 23, and guard plates 24. The central shaft 22 is fixed on the rotating shaft 2. The guard plates 24 are located on both sides of the central shaft 22. Several auxiliary rods 23 are arranged around the central shaft 22, and each end is connected to two guard plates 24 to ensure that the hose will not fall off or tangle during the reeling process. The hose reel is driven to rotate by the central shaft 22, realizing the automatic reeling of the hose while pushing the sprinkler truck.

[0034] The sprinkler system includes a multi-channel water pipe 25 and a spray gun 26. The multi-channel water pipe 25 is connected to the crossbeam 7 via a third sleeve 15 and has several water outlets 27. The spray gun 26 is detachably connected to the water outlets 27 of the multi-channel water pipe 25, allowing users to select the appropriate spray gun 26 and water outlet method according to their irrigation needs.

[0035] The push handle 6 is equipped with a ground support plate 28. When the spray truck is parked, the ground support plate 28 can be lowered to increase the stability of the spray truck and prevent it from tipping over.

[0036] In actual production, the sprocket 4 and flywheel 3 can be installed on the inner or outer side of the riser 8 as needed. (See attached diagram.) Figure 5 A large gap is maintained between wheel 1 and riser tube 8, with sprocket 4 positioned between them, i.e., sprocket 4 is on the outside of riser tube 8. At this time, flywheel 3 and sprocket 4 are also on the outside of riser tube 8, and the two are connected by chain 5. (See attached diagram.) Figure 6The distance between wheel 1 and riser 8 is small. The axle of wheel 1 extends inward through riser 8, so sprocket 4 is located inside riser 8. At this time, flywheel 3 is also located inside riser 8. The two are connected by chain 5.

[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
