[0038] During specific operation, the electric push rod 212 is used to control the central hinged rod of an X-shaped articulated frame close to the horizontal main pipe 24 to move in the horizontal direction. During the movement, the central hinged rods of the articulated frame group 211 drive the various sections of the multi-stage telescopic tube 214 to extend synchronously, so as to adjust the horizontal extension range of the horizontal main pipe 24. When it is shortened to the minimum range, the overall footprint of the equipment can be effectively saved.

[0039] See also Figure 1 and Figure 4 The height adjustment component 22 includes a screw rod 222 rotatably connected to the inside of the frame 3, and a guide rod 223 symmetrically fixedly connected to the inside of the frame 3.

[0040] During specific operation, the motor 221 controls the screw rod 222 to rotate, and the screw rod 222 drives the moving seat 224 to move up and down along the guide rod 223, thereby driving the horizontal main pipe 24 to move up and down through the moving seat 224, and adaptively adjusting the irrigation height according to the irrigation position required by the crop.

[0041] See also Figure 6 A distance adjustment component 26 for controlling the distance between the two main watering heads 251 is provided between the two main watering heads 251. The distance adjustment component 26 includes a T-shaped mounting seat 262 fixedly sleeved on the lower side of the vertical water pipe.

The driving gear 263 drives the rotating arm 265 to rotate and controls the movable sleeve 266 to drive the two connecting hoses 268 to change the bifurcation angle, so as to adjust the irrigation distance of the main irrigation head 251. Since different crops have different water flow resistance capabilities, the main irrigation head 251 is far away from the crops, which can prevent the water flow from directly hitting the crops with weaker resistance capabilities, and can directly contact and irrigate the crops with stronger resistance capabilities.

[0043] See also Figure 6 , Figure 7 and Figure 8The conversion assembly 27 includes a sliding tube 279 tightly slidably connected in the vertical branch pipe 25. The sliding tube 279 is provided with perforations 1 corresponding to a plurality of sprinkler sub-heads 252.

When the vertical branch pipe 25 is in a vertical state, the protrusion 277 points in the same direction as the sprinkler head 252. A stop weight ball 276 is fixedly connected to the cam 275. The stop weight ball 276 and the protrusion 277 are vertically distributed. The rotation center of the cam 275 is fixedly connected to a connecting pin 274. The two ends of the connecting pin 274 are rotatably connected to support plates 27 8. The two side support plates 278 are fixedly connected to the bottom of the T-shaped mounting seat 262. A rotating pipe component 23 for controlling the rotation of the horizontal main pipe 24 is provided in the middle of the horizontal main pipe 24. A locking component 28 for locking the sliding pipe 279 when the vertical branch pipe 25 is in a horizontal state is provided on one side support plate 278. The rotating pipe component 23 includes a rotating gear 231 fixedly connected to the middle of the horizontal main pipe 24.

[0044] During specific operation, the vertical branch pipe 25 is in a vertical state, the second perforation of the sliding pipe 279 corresponds to the installation position of the connecting hose 268, the first perforation is staggered with the position of the sprinkler sub-head 252, and the second spring 271 is in a stress-free state. When releasing water, water flows out from the main irrigation head 251 for irrigation, and the electric push rod 233 controls the moving rack 232 to move downward to drive the rotating gear 231 to rotate and control the horizontal main pipe 24 to rotate 90°, so that the vertical branch pipe 25 is converted to a horizontal state, and the stop weight ball 276 can keep the cam 275 in its original state, and the contact roller 273 will roll around the cam 275. The sliding pipe 279 is affected by the change in the distance between the rotation center axes of the cam 275 and the contact roller 273, and will move up along the vertical branch pipe 25 and press the second spring 271.

After the horizontal main pipe 24 rotates 90°, the contact roller 273 will abut against the tip of the protrusion 277, and the locking elastic column 281 will be stuck in the locking recess 283. In this state, the installation positions of the perforation 2 and the connecting hose 268 are staggered, and the perforation 1 corresponds to the position of the sprinkler sub-head 252. When releasing water, water flows out from the sprinkler sub-head 252 for sprinkler irrigation, and the vertical branch pipe 25 is in a horizontal state for sprinkler irrigation, which can save water resources. At the same time, the same position can be repeatedly sprinkled for many times, and it can ensure that the crops absorb water fully. When the vertical branch pipe 25 is in a horizontal state, the water flow inside the sliding pipe 279 has a certain water pressure, and the locking component 28 limits the sliding pipe 279 to ensure that the sliding pipe 279 does not deviate, affecting the correspondence between the perforation 1 and the sprinkler sub-head 252.
