These soil characteristics pose severe challenges to agricultural production, and these saline-alkali soils need to be improved. Irrigation is an important measure in the improvement of saline-alkali soils.

[0020] S3, start the water pump, the external water source is filtered through the filter, and then transported to the water spray pipe and the telescopic pipe in sequence through the water supply pipe and the connecting pipe, the water is divided into multiple streams through multiple water spray holes, and sprayed upward at high speed, and the rotating water diffuser sprays the sprayed water outward;

[0021] S4.

Then the forward and reverse motors are started to drive the rotating gear, the annular gear sleeve and the adjusting sleeve to rotate, and the water diffuser is driven to rotate inside the water spray hood through the arc rod and the fixed rod. At the same time, the adjusting sleeve rotates upward inside the two arc-shaped threaded sleeves, and the industrial sleeve is lifted up to increase the height of the water spray hood. Then the output end of the forward and reverse motors will automatically rotate in the opposite direction, driving the adjusting sleeve spiral to rotate downward, gradually lowering the height of the water spray hood. The cooperation between the irrigation component and the adjusting component can realize the functions of moving up and down, adjusting different heights and rotating water spraying, and the water spraying area and the water spraying angle are adjusted. Even if the local soil is uneven, water can be sprayed evenly, which greatly improves the water spraying range, is conducive to evenly distributing water to the entire sprinkler irrigation area, improves the utilization rate of water, and effectively avoids uneven water spraying.

[0024] 2. When the present invention is used, when the water spray hood reaches a suitable height, the forward and reverse motors are paused, the limit rod is inserted into the threaded hole and the movable hole at the corresponding position, and then the threaded shaft is rotated in the opposite direction so that one end of the limit rod is inserted into the limit groove to limit the adjustment sleeve, and then the threaded rod is rotated to pull the arc threaded sleeve outward through the T-block so that the arc threaded sleeve is separated from the adjustment sleeve, and under the action of the height fixing component, the effect of adjusting and fixing the height of the water spray hood is achieved.

[0039] In this embodiment, when in use, the four threaded shafts 303 are respectively screwed to rotate outward in the corresponding threaded holes 302, driving the four limiting rods 304 to rotate outward in the corresponding movable holes 216, so that one end of the four limiting rods 304 is rotated out from the inside of the limiting groove 309, at which time the limiting ring 308 loses its limit, and the outer surface of the limiting ring 308 does not contact the inner walls of the two arc-shaped threaded sleeves 207. Then the forward and reverse motor 203 is started, and the rotation of the output end of the forward and reverse motor 203 drives the rotating gear 204 to rotate, further drives the ring gear sleeve 205 and the adjustment sleeve 206 to rotate, and drives the arc-shaped rod 208 and the fixed rod 209 to rotate together, and further drives the water diffuser 210 to rotate inside the water spraying cover 108, and sprays multiple streams of water sprayed from the water spraying hole 110 outward, thereby achieving the effect of rotary sprinkler irrigation and expanding the water spraying range.

The invention solves the problem that during the use of the irrigation device for improving the saline-alkali soil in the Yellow River Delta, the nozzle can usually only maintain a height for water spraying. When the terrain of the sprinkler irrigation area is uneven and there are ups and downs, uneven sprinkler irrigation will occur, affecting the soil improvement effect.

[0040] Embodiment 2: Figure 2-Figure 3 and Figure 5-Figure 9As shown, an adjustment component 2 and a height fixing component 3 are arranged on the top of the irrigation component 1. The height fixing component 3 includes a fixing cover 301. A plurality of threaded holes 302 are equidistantly provided on the outer surface of the fixing cover 301. Threaded shafts 303 are threadedly embedded in the interiors of four threaded holes 302. One end of each of the four threaded shafts 303 is fixedly installed with a limiting rod 304. Two fastening holes 305 are arranged near the top on the outer surface of the fixing cover 301. Threaded rods 306 are threadedly embedded in the interiors of the two fastening holes 305. T-blocks 307 are fixedly installed at one end of each of the two threaded rods 306. A limiting ring 304 is fixedly installed near the bottom on the outer surface of the adjustment sleeve 206. 8. A limiting groove 309 is provided on the outer surface of the limiting ring 308, and one end of each of the four limiting rods 304 is movably embedded in the limiting groove 309. A T-slot 215 is provided on the outer surfaces of the two arcuate threaded sleeves 207 near the top, and a plurality of movable holes 216 are equidistantly provided on the outer surfaces of the two arcuate threaded sleeves 207.

The bottom of the fixed cover 301 is fixedly mounted on the top of the fixed seat 201, and the two arcuate threaded sleeves 207 are both located inside the fixed cover 301.

[0041] In this embodiment, during use, when it is necessary to spray water on the soil in a certain place in a targeted manner, the forward and reverse motors 203 are used to drive the adjustment sleeve 206 to rotate spirally upward in the two arc-shaped threaded sleeves 207, and drive the limiting ring 308 to rotate upward inside the two arc-shaped threaded sleeves 207. When the water spray cover 108 reaches a suitable height, the forward and reverse motors 203 are paused, and then the four threaded shafts 303 are screwed out of the threaded holes 302 at the bottom, and the corresponding limiting rods 304 are pulled out from the movable holes 216 and the threaded holes 302. Then, according to the height position of the limiting ring 308, the limiting rod 304 is inserted into the threaded holes 302 and the movable holes 216 at the corresponding positions.

When some water flows in along the gap between the work sleeve 111 and the adjustment sleeve 206, the water can be guided to the drainage hole 214 under the protection of the waterproof cover 211, and then the water is discharged to the outside through the drainage hole 214 and the drainage cover 212, thereby playing a protective role and preventing some water from flowing into the adjustment sleeve 206 along the gap between the work sleeve 111 and the adjustment sleeve 206, affecting the normal operation of the forward and reverse motors 203. When the water spray cover 108 reaches a suitable height, the forward and reverse motors 203 are paused, and the limiting rod 304 is inserted into the threaded hole 302 and the movable hole 216 at the corresponding position according to the height position of the limiting ring 308. At this time, the threaded shaft 303 moves to the threaded hole 302 at the corresponding position, and then the threaded shaft 303 is rotated in the opposite direction, so that one end of the limiting rod 304 is inserted into the limiting groove 309, thereby limiting the limiting ring 308 after the adjustment position, that is, limiting the adjustment sleeve 206, and then the threaded rod 304 is rotated. 6, so that it rotates outward in the fastening hole 305, further driving the T-block 307 to rotate in the T-slot 215. As the threaded rod 306 moves outward, the T-block 307 pulls the arc-shaped threaded sleeve 207 outward, so that the arc-shaped threaded sleeve 207 is separated from the adjustment sleeve 206. The forward and reverse motor 203 is started again, and the adjustment sleeve 206 is driven to rotate forward and reverse, so that the water spray cover 108 rotates and sprays water at a fixed height, so that the soil in this range can be sprayed with water in a targeted manner.
