[0002] Irrigation robots are needed in daily agricultural and vegetation irrigation operations, and the sprinkler head used for irrigation is an indispensable component of irrigation robots.

[0003] For example, patent CN220755960U discloses an agricultural irrigation robot, which relates to the field of agricultural irrigation technology. It includes a base with two symmetrically distributed rollers rotatably connected to both sides of the base. A water tank is fixedly connected to one side of the top of the base. The rollers allow the base to move on the ground. A water pump draws water from the tank into a fixed pipe and sprays it out from the nozzle to irrigate crops. A connecting seat slides on the upright plate, which in turn drives the water storage box to slide up and down, allowing irrigation of crops at different heights. The water storage box slides on one side of the connecting seat, allowing irrigation of crops at different locations, thereby increasing the area of ​​irrigation.

[0004] During use, the irrigation robot described above has a fixed spray volume from its irrigation nozzles, which cannot be adjusted according to the different flow rates required by the irrigated vegetation or crops. To change the flow rate, different nozzles need to be replaced, which reduces the practicality of the nozzles to some extent. Utility Model Content

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention allows for adjustments based on the required irrigation water flow and spraying range. Personnel can manually pull the frame beforehand, causing the inner guide post and limiting block to disengage from the corresponding tooth groove of the fixed gear on the positive and negative lead screw under the guidance of the guide groove. Then, the manual twisting block rotates the positive and negative lead screw. At this time, the two lead screw sleeves interacting with the lead screw can move relative to each other, along with their respective fixed water-blocking guide blocks, in conjunction with the guide groove, until the two water-blocking guide blocks can block the spray holes at the front of the nozzle body, thus achieving the adjustment purpose. After adjustment, the frame is slowly released, allowing the limiting block to engage with the corresponding tooth groove of the gear under the elastic reset of the return spring. It is worth mentioning that when the nozzle body is not in use, personnel can control and guide the two water-blocking guide blocks to contact and close, thereby reducing the entry of external dust and impurities into the spray holes.

[0019] When the irrigation robot is needed to irrigate crops or vegetation, the staff can use two sets of installation mechanisms to install the mounting frame and the nozzle body in the middle section of the irrigation robot at the pre-installation point of the nozzle. Then, the staff will thread the threaded sleeve on the outside of the fixed sleeve around the rotating shaft at one end of the water pipe into the mounting screw groove in the middle of the connecting cylinder at the rear end of the nozzle body, thereby forming a stable connection between the water pipe and the nozzle body.
