[0002] Farmland irrigation mainly refers to irrigation operations in agricultural farming areas. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, the water requirements of crops cannot be met due to insufficient or uneven precipitation.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 3When the water pipe 2 is rotated, the nozzle 5 is connected to the nozzle 6 and the nozzle 7 is connected to the nozzle 8. When the water pipe 2 is rotated, the nozzle 5 is connected to the nozzle 8 and the nozzle 7 is connected to the nozzle 8.

[0033] Reference Figure 2 、 Figure 4 and Figure 5 The upper surface of the water spray barrel 4 is fixedly connected with an electric push rod 6, and the top of the electric push rod 6 is fixedly connected with a protective cover 7. When the electric push rod 6 is started, the protective cover 7 can be driven to move linearly in the up and down directions. The protective cover 7 is sleeved on the outside of the water spray barrel 4 to protect the outside of the water spray barrel 4 to prevent the water spray barrel 4 from being damaged by foreign objects. When the irrigation device needs to be used, the electric push rod 6 can be started to drive the protective cover 7 to move upward and leave the outside of the water spray barrel 4, so that the sprinkler head 5 can be used normally.

[0034] A fixed cylinder 8 is fixedly connected to the outside of the protective cover 7. A through hole 9 is provided on the outside of the protective cover 7. The fixed cylinder 8 is fixedly connected to the left end of the through hole 9. The through hole 9 runs through the protective cover 7. A plug 10 is provided inside the through hole 9. The size of the plug 10 is adapted to the size of the nozzle 5. When the plug 10 enters the inside of the nozzle 5, the nozzle 5 can be sealed to prevent external dust, impurities or insects from entering the water pipe 2. The number and position of the fixed cylinder 8, the through hole 9 and the plug 10 are adapted to the number and position of the nozzle 5. The plug 10 can enter the through hole 9 for temporary storage. The right side surface of the plug 10 is a circular arc surface. When the plug 10 moves up and down, the nozzle 5 can squeeze the plug 10 along the arc surface of the plug 10, so that the plug 10 moves toward the fixed cylinder 8.

[0035] The interior of the fixed cylinder 8 is provided with an extrusion unit, which includes a telescopic rod 101, which is fixedly connected to the left inner wall surface of the fixed cylinder 8, and a spring 102 is sleeved on the outer side of the telescopic rod 101. The right end of the telescopic rod 101 is fixedly connected to a connecting block 103, and the size of the connecting block 103 is adapted to the size of the fixed cylinder 8. The connecting block 103 is plugged into the inside of the through hole 9, and the through hole 9 can guide and limit the movement of the connecting block 103, so that the connecting block 103 can only move in a straight line to avoid offset. 3 is fixedly connected to the right side surface of the plug 10. When the connecting block 103 moves, the plug 10 can be driven to move synchronously. The plug 10 can move up and down synchronously with the protective cover 7 through the connection between the extrusion unit and the fixed cylinder 8. The left end of the spring 102 is fixedly connected to the left inner wall of the fixed cylinder 8, and the right end of the spring 102 is fixedly connected to the left surface of the connecting block 103. When the connecting block 103 moves toward the inside of the fixed cylinder 8, it can squeeze the telescopic rod 101 and the spring 102, so that the spring 102 is compressed to generate elastic potential energy.

[0036] When the nozzle 5 needs to be used, the electric push rod 6 can be started to drive the protective cover 7 to move upward. At this time, the plug 10 can move upward synchronously with the protective cover 7, and the nozzle 5 can be squeezed along the arc of the plug 10 to make the plug 10 move toward the inside of the fixed cylinder 8 to avoid hindering the movement of the protective cover 7, so that the nozzle 5 is opened and multi-angle irrigation is carried out. When the irrigation is completed, the electric push rod 6 can be started to drive the protective cover 7 to move down and reset. At this time, the nozzle 5 will still be squeezed along the arc of the plug 10 to make the plug 10 move toward the inside of the fixed cylinder 8 to avoid hindering the movement of the protective cover 7. When the protective cover 7 is moved and reset, the plug 10 will be aligned with the nozzle 5. At this time, the plug 10 can be reset under the action of the elastic potential energy of the spring 102, enter the nozzle 5 to seal it, and prevent external debris from entering the water pipe 2 and causing internal pollution of the device.

[0037] Reference Figure 2 and Figure 4 The lower side of the outer wall of the water spray barrel 4 is fixedly connected to a bottom plate 11. When the protective cover 7 moves down to protect the outside of the water spray barrel 4, the bottom plate 11 can seal the bottom of the protective cover 7 to prevent debris from entering the interior of the protective cover 7. The upper surface of the water spray barrel 4 is fixedly connected to a guide rod 12. A guide hole 13 is provided on the upper surface of the protective cover 7. The size of the guide rod 12 is adapted to the size of the guide hole 13. The guide rod 12 is plugged into the inside of the guide hole 13. The guide rod 12 can perform a linear motion in the up and down directions inside the guide hole 13. By cooperating with the provided guide rod 12 and the guide hole 13, the movement of the protective cover 7 can be guided and limited, so that the protective cover 7 can only perform a linear motion in the up and down directions, thereby avoiding offset and causing breakage at the connection with the electric push rod 6.

[0038] Working principle: When the irrigation device is not in use, the electric push rod 6 can be started to drive the protective cover 7 to move downward to protect the outside of the water spray barrel 4. During the downward movement of the protective cover 7, the nozzle 5 can squeeze the plug 10 along the arc surface of the plug 10, so that the plug 10 moves toward the inside of the fixed tube 8, and squeezes the spring 102 and the telescopic rod 101, so that the spring 102 is compressed to generate elastic potential energy. When the protective cover 7 moves to the desired position, the plug 10 will be aligned with the nozzle 5. At this time, the plug 10 will enter the nozzle 5 under the action of the elastic potential energy of the spring 102, and seal it to prevent dust, impurities and insects in the outside air from entering the device and causing pollution. At this time, the bottom plate 11 can seal the bottom of the protective cover 7 to prevent debris from entering the protective cover 7.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
