[0025] Figure 1-Figure 4 This is an embodiment of the present utility model. The specific problem addressed by this specific embodiment is: an irrigation device for high-standard farmland construction disclosed in application number 202322152084.8, the nozzle proposed in this disclosed scheme is vertically upward, and the water mist generated can irrigate the farmland in a circular manner with the spray radius of the nozzle in a windless environment, but in a windy environment, irrigation deviation will occur, thereby causing water shortage in some farmland. To solve the above existing specific problems, this solution utilizes the sprinkler head 33 to rotate circumferentially on the sprinkler pipe 31, thereby generating circumferential irrigation of the farmland, and the spray water flow it generates is a parabolic drop after direct injection. Even if it is affected by wind, the offset liquid it generates is smaller than the offset generated by the scattered water flow, thereby reducing the lack of water in the farmland.

The water pipe 1 is provided with a plurality of water receiving levels 2, and a sprinkler device 3 for circumferential irrigation of the farmland is detachably installed on the water receiving level 2. The setting of the plurality of water receiving levels 2 can effectively adjust the installation spacing of adjacent sprinkler pipes 31 on the water pipe 1. Therefore, the number of sprinkler pipes 31 installed on the water pipe 1 can be adjusted according to the area of ​​the farmland and the degree of water shortage, which can more effectively improve the adaptability to the farmland.

[0027] The sprinkler device 3 includes a sprinkler pipe 31 and a sleeve 32 that is sleeved onto the sprinkler pipe 31. A sprinkler head 33 is mounted at one end of the sleeve 32 to output water to the farmland for irrigation. The sleeve 32 is mounted at an angle to the sprinkler head 33. The sleeve 32 has a water passage cavity 36 inside that communicates with the sprinkler pipe 31. The sprinkler head 33 has a plurality of spray holes 35 through which water flows outward.

The water inlet cavity is connected to the water passage cavity 36. The sleeve 32 is rotatably mounted on the sprinkler pipe 31 and drives the sprinkler head 33 to rotate circumferentially around the sprinkler pipe 31. The water irrigating the farmland is output from the sprinkler head 33 and provides range coverage for the crops to be irrigated in the farmland. Several adjacent sprinkler pipes 31 can produce cross-coverage of the irrigation range, thereby covering the entire farmland to be irrigated.

[0028] Water inlet points 2 are evenly spaced on the water pipe 1. A water pipe 4 is installed on the water inlet points 2, extending therein and interferingly filling the water pipe. The water pipe 4 is provided with a threaded groove and a removable top cap 5.

When the spray hole 35 is blocked, the top cap 5 is removed from the unused water diversion pipe 4, and the boss 6 is used to push the top into the spray hole 35 to clear the spray hole 35. The spray pipe 31 is threadedly connected to the water diversion pipe 4, and a connecting arm 7 connecting adjacent spray pipes 31 is sleeved on the wall of the spray pipe 31.
