[0002] Hand-push sprinkler is a light and small sprinkler, mainly used for farmland irrigation. It has a simple structure, small size, flexible use and low price. It is one of the main forces of sprinkler equipment in my country. The working principle of hand-push sprinkler is to pump water from the water source through a water pump, then transport it to the field through a pipeline, and finally spray the water on the crops through a nozzle. Since this type of sprinkler often needs to change position in the field, most sprinklers use easy-to-operate self-priming centrifugal sprinkler pumps to reduce the trouble of pumping water after moving.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention opens the first valve body on the driving delivery pipe and then opens the fourth valve body on the driving discharge pipe, so that a part of the pressurized water delivered to the sprinkler head through the sprinkler pipe can be diverted to enter the driving seat through the driving delivery pipe, and because the fourth valve body on the driving discharge pipe is in an open state, the diverted pressurized water can impact the driving impeller after entering the driving seat, so that the driving impeller can drive the rotating rod to rotate, and the rotating rod can drive the driving roller to rotate when rotating, so that the guide protrusion is forced to slide in the circulating rail groove, and the sliding process of the guide protrusion can drive the moving sleeve on the outer surface of the driving roller to move back and forth, and the moving sleeve that moves back and forth can The columnar connecting block can be driven to slide on the inner side of the arc guide groove via the transverse sliding seat, and the columnar connecting block can drive the elevation adjustment cylinder and the guide pin rod to move synchronously while the columnar connecting block moves, and the guide pin rod can drive the sprinkler head to realize a reciprocating swinging motion via the adjusting plate with the assistance of the sliding seat and the fixed seat during the movement, so that the sprinkler machine can have the ability of cyclic reciprocating spraying irrigation, and when the sprinkler head swings to the required rotational sprinkler irrigation angle, the fourth valve body on the driving drain pipe is closed, and the driving drain pipe of the fourth valve body is closed to prevent the diverted pressure water from continuing to flow, thereby driving the impeller to be unable to drive the rotating rod to continue to rotate, thereby being able to adjust the rotational sprinkler irrigation angle of the sprinkler head. When the nozzle is fixed, and when it is necessary to adjust the inclination angle of the nozzle according to the situation, the fourth valve body on the driving discharge pipe is opened again, and then the sixth valve body on the elevation delivery pipe is opened, and then the pressure water in the driving discharge pipe is diverted through the elevation delivery pipe into the elevation adjustment cylinder, so that the elevation adjustment cylinder can drive the guide pin rod to extend upward, and because the guide pin rod slides in the guide groove on the inner surface of the adjustment plate, the nozzle is turned downward with the connection in the fixed seat as the center of the circle. After the downward turning elevation angle is determined, the sixth valve body on the elevation delivery pipe and the fourth valve body on the driving discharge pipe can be closed, and the fifth valve body on the elevation discharge pipe can be opened. Afterwards, under the influence of gravity, the water in the elevation adjustment cylinder can be sent into the driving drainage pipe through the elevation drainage pipe and discharged, thereby making the extended height of the elevation adjustment cylinder can be reduced. In the process of the extended end of the elevation adjustment cylinder being lowered, the guide pin rod can slide in the guide groove on the inner surface of the adjustment plate, so that the sprinkler head can flip upward in elevation with the connection in the fixed seat as the center of the circle. After the upward flipping elevation is determined, the fifth valve body on the elevation drainage pipe can be closed. It is easy to use, and the conveniently adjusted spraying angle can make the spraying irrigation more uniform, which can save water resources, and the pressure of the discharged water can be adjusted, thereby reducing the consumption of excess energy.

[0016] 2. The present invention opens the first valve body on the driving delivery pipe, and then opens the second valve body on the lifting delivery pipe, so that the diverted pressure water body can enter the height lifting cylinder, thereby raising the extended end of the height lifting cylinder.

When the use height of the nozzle is determined, the first valve body on the driving delivery pipe and the second valve body on the lifting delivery pipe can be closed. When the height of the nozzle needs to be lowered, it is only necessary to open the third valve body on the lifting discharge pipe, so that the water in the height lifting cylinder enters the driving discharge pipe under the influence of gravity and is discharged outward, thereby adjusting the spraying height of the nozzle. When the use height of the nozzle is determined, the third valve body on the lifting discharge pipe can be closed. BRIEF DESCRIPTION OF THE DRAWINGS

The inner cavity of the driving seat 13 is movably connected with a rotating rod 34 that passes through the rear side of the driving seat 13 through a bearing. The outer surface of the rotating rod 34 located in the driving seat 13 is fixedly connected with a driving impeller 42, and the outer surface of the rotating rod 34 located at the rear of the driving seat 13 is fixed. A driving roller 25 is connected, and a circulating track groove 32 is opened on the outer surface of the driving roller 25.

The driving delivery pipe 17, the driving discharge pipe 31, the elevation delivery pipe 14 and the elevation discharge pipe 39 are all elastic hoses.

[0025] The technical solution of the present invention is that the sprinkler can be moved to the use position by setting the main body 1 of the hand-push sprinkler. Then, the connection bolts between the bolt connection seat 8 and the main body 1 of the hand-push sprinkler are removed, and the sprinkler pipe wrapped on its surface is pulled with the assistance of the tube-collecting roller 2, so that the mobile sprinkler frame 6 can be moved over a long distance after separation and used. Then, the water inlet pipe 3 is sent into the water source. Then, when the self-priming centrifugal sprinkler pump body 4 is working, the water in the water source can be sent into the sprinkler head 5 through the sprinkler pipe and then sprayed outward, thereby realizing the ability of water spraying. When it is necessary to adjust the rotation of the sprinkler head 5 according to the usage situation, the water in the water source can be sprayed outward. When the irrigation angle is increased, after the first valve body 16 on the driving delivery pipe 17 is opened, the fourth valve body 38 on the driving discharge pipe 31 is opened, and then a part of the pressurized water body sent to the sprinkler head 5 through the sprinkler pipe can be diverted to enter the driving seat 13 through the driving delivery pipe 17. Since the fourth valve body 38 on the driving discharge pipe 31 is in an open state, the diverted pressurized water body can impact the driving impeller 42 after entering the driving seat 13, so that the driving impeller 42 can drive the rotating rod 34 to rotate, and when the rotating rod 34 rotates, it can drive the driving roller 25 to rotate, so that the guide protrusion 24 is forced to slide on the circulation track The guide protrusion 24 can drive the moving sleeve 27 to move forward and backward on the outer surface of the driving roller 25 during the sliding process, and the moving sleeve 27 that moves forward and backward can drive the columnar connecting block 23 to slide on the inner side of the arc-shaped guide groove 36 through the transverse slide seat 37 (wherein the transverse slide seat 37 slides left and right on the outer surface of the upper end of the moving sleeve 27, which can assist the columnar connecting block 23 to slide smoothly on the inner side of the arc-shaped guide groove 36), and when the columnar connecting block 23 moves, it can drive the elevation adjustment cylinder 22 and the guide pin rod 41 to move synchronously, and when the guide pin rod 41 moves, it can move between the sliding seat 21 and the fixed seat 10 With the assistance of the adjusting plate 15, the sprinkler head 5 can be driven to realize a reciprocating swinging motion (at this time, the fixing seat 10 can drive the sliding seat 21 to rotate and slide back and forth on the upper end of the fixing sleeve 20), so that the sprinkler has the ability of cyclic reciprocating spraying irrigation, and when the sprinkler head 5 swings to the required rotational spraying angle, the fourth valve body 38 on the driving drain pipe 31 is closed, and the driving drain pipe 31 with the fourth valve body 38 closed can prevent the diverted pressure water from continuing to flow, and then the driving impeller 42 cannot drive the rotating rod 34 to continue to rotate, so that the rotational spraying angle of the sprinkler head 5 can be fixed; When it is necessary to adjust the inclination angle of the nozzle 5 according to the situation, the fourth valve body 38 on the driving drainage pipe 31 is opened again, and then the sixth valve body 40 on the elevation delivery pipe 14 is opened, and then the pressure water in the driving drainage pipe 31 will be diverted through the elevation delivery pipe 14 into the elevation adjustment cylinder 22, so that the elevation adjustment cylinder 22 can drive the guide pin 41 to extend upward, and because the guide pin 41 slides in the guide groove on the inner surface of the adjustment plate 15, the nozzle 5 is turned downward with the connection in the fixed seat 10 as the center of the circle. After the downward turning elevation is determined, the sixth valve body 40 on the elevation delivery pipe 14 and the fourth valve body 38 on the driving drainage pipe 31 can be closed. After the fifth valve body 33 on the elevation drainage pipe 39 is opened, the water in the elevation adjustment cylinder 22 can be discharged into the driving drainage pipe 31 through the elevation drainage pipe 39 under the influence of gravity (such as Fig. 9 A one-way valve is provided at one end of the elevation drainage pipe 39 shown, so that the drainage pipe 31 is driven not to flow back into the elevation adjustment cylinder 22), thereby enabling the extension height of the elevation adjustment cylinder 22 to decrease. During the process of the extension end of the elevation adjustment cylinder 22 descending, the guide pin rod 41 can slide in the guide groove on the inner surface of the adjustment plate 15, so that the sprinkler head 5 can flip upward in elevation with the connection in the fixed seat 10 as the center of the circle. After the upward flipping elevation angle is determined, the fifth valve body 33 on the elevation drainage pipe 39 can be closed. Then, when the sprinkler head 5 swings to the required rotational sprinkler irrigation angle, the fourth valve body 38 on the driving drainage pipe 31 and the first valve body 16 on the driving delivery pipe 17 are closed to complete the adjustment of the tilt elevation angle. It is easy to use, and the easily adjustable spraying angle can make the spraying irrigation more uniform, save water resources, and the pressure that is conducive to discharging the water body can be adjusted, thereby reducing the consumption of excess energy.

[0026] Embodiment 2

[0027] Based on the first embodiment, the present invention is as follows Figure 1-Figure 9 As shown, it is disclosed that the auxiliary nozzle 9 is fixedly mounted on the left end of the rear side of the nozzle 5 , and the right side of the auxiliary nozzle 9 is connected to an end of the driving drainage pipe 31 away from the driving seat 13 .

[0028] The technical solution of the present invention is that the auxiliary nozzle 9 can be connected with the end of the driving drainage pipe 31 through the setting, so that the water body in the adjustment process can be guided and sprayed to a distant place. In particular, when the reciprocating spraying irrigation mode of the sprinkler is selected, the pressurized water body diverted therefrom can cooperate with the nozzle 5 to spray at a slightly closer distance, so as to expand the spraying range of the sprinkler and speed up the spraying irrigation efficiency of the sprinkler.

[0029] Embodiment 3

[0030] Based on the first embodiment, the present invention is as follows Figure 1-Figure 9As shown, a height lifting cylinder 11 is fixedly installed on the lower end of the left side of the protective pipe sleeve 7, and the protruding end of the height lifting cylinder 11 is fixedly connected to a connecting plate 18 fixedly connected to the lower end of the left side of the fixed sleeve 20.

[0031] The technical solution is as follows: after opening the first valve body 16 on the driving delivery pipe 17, the second valve body 28 on the lifting delivery pipe 12 is opened, so that the diverted pressure water can enter the height lifting cylinder 11, so that the extended end of the height lifting cylinder 11 is raised, and when the extended end of the height lifting cylinder 11 drives the connecting plate 18 to extend, the connecting plate 18 can drive the fixed sleeve 20 to slide upward in the protective pipe sleeve 7, and the fixed sleeve 20 can drive the sliding seat 21 to move synchronously when it moves, so that the spraying height of the sprinkler 5 can be adjusted upward. When the use height of the sprinkler 5 is determined, the first valve body 16 on the driving delivery pipe 17 and the second valve body 28 on the lifting delivery pipe 12 can be closed. When the height of the sprinkler 5 needs to be lowered, it is only necessary to open the third valve body 29 on the lifting drainage pipe 19, so that the water in the height lifting cylinder 11 enters the driving drainage pipe 31 under the influence of gravity and is discharged outward (such as Fig. 9 One end of the lifting and draining pipe 19 shown is provided with a one-way valve, thereby driving the draining pipe 31 not to flow back into the height lifting cylinder 11), so that the protruding end of the height lifting cylinder 11 can be lowered, and when the protruding end of the height lifting cylinder 11 drives the connecting plate 18 to descend, the connecting plate 18 can drive the fixed sleeve 20 to slide downward in the protective pipe sleeve 7, and when the fixed sleeve 20 moves, it can drive the sliding seat 21 to move synchronously, thereby being able to lower the spraying height of the nozzle 5. When the use height of the nozzle 5 is determined, the third valve body 29 on the lifting and draining pipe 19 can be closed. It should be noted that when the sliding seat 21 moves up and down, and with the assistance of the limiting guide strip 30, the driving seat 13 can move synchronously, and thus will not affect the adjustment of the elevation angle and the rotation angle.
