A cross bar 29 is fixedly installed horizontally on the side of the sleeve plate 28, and the end of the cross bar 29 is fixedly installed on the end of the movable block 33; Furthermore, the rotation of the first pulley 24 drives the rotary tiller 5 to rotate, so as to break up the compacted soil, and the rotation speed of the rotary tiller 5 can be adjusted in real time according to the moisture content inside the soil, thereby avoiding the occurrence of excessive compaction of the soil (poor water permeability and air permeability) and excessive fineness (poor drainage and poor air permeability).

[0024] The working principle of the present invention is as follows: first, the device is placed in the saline-alkali land that needs irrigation and connected to the traction machine through the traction frame 4; Then, the hydraulic telescopic rod 3 drives the connecting plate 6 to move downward, and the connecting plate 6 moves downward to drive the probe 9, the furrowing plate 8, the covering plate 10 and the V-shaped frame 7 to move downward. The V-shaped frame 7 moves downward to drive the rotary tiller 5 and the connecting parts thereon to move downward together, so as to insert the probe 9, the furrowing plate 8 and the covering plate 10 into the soil, ensuring that the bottom of the probe 9 can contact the soil to detect the moisture content inside the soil, and the rotary tiller 5 can contact the soil to ensure that the rotary tiller 5 can break up the compacted soil; Then, the liquid pump and the drive motor 31 are turned on, and the traction mechanism is used to drive the base 1 to move. The liquid pump will then spray the water in the water tank 2 through the horizontal pipe 16 and the nozzle 17 to irrigate the saline-alkali soil. The drive motor 31 will drive the second conical column 26 to rotate. The rotation of the second conical column 26 will drive the second belt 27 to rotate. The rotation of the second belt 27 will drive the first conical column 25 to rotate. The rotation of the first conical column 25 will drive the second pulley, the first belt 23 and the first pulley 24 to rotate. The rotation of the first pulley 24 will drive the rotary blade 5 to rotate, thereby breaking up the compacted soil. First, if the soil moisture content inside the saline-alkali land is normal, the two currents passing through the two probes 9 and the electromagnet 14 are normal, and the electromagnet 14 generates normal magnetism. Further, the electromagnet 14 will cause the slider 12 of the magnetic material to move a certain distance toward the electromagnet 14. The movement of the slider 12 drives the vertical plate 15 to move and causes the spring rod 13 to generate tension. It should be noted that when the probe 9 is not inserted into the soil, no current passes through the electromagnet 14. The movement of the vertical plate 15 drives the rack 18 and the movable block 33 to move. The movement of the rack 18 drives the first gear 19 to rotate. The rotation of the first gear 19 drives the rotating rod 20 to rotate. The rotation of the rotating rod 20 drives the first bevel gear 21 to rotate. The rotation of the first bevel gear 21 drives the second bevel gear 22 The second bevel gear 22 rotates, driving the fixed rod 35 and the ball valve 34 to rotate, so that the ball valve 34 can be in a half-open state to control the water output through the sprinkler head 17, avoiding the occurrence of droughts and floods due to more or less irrigation. In addition, the movable block 33 moves to drive the cross bar 29 to move, the cross bar 29 moves to drive the sleeve 28 to move, and the sleeve 28 moves to drive the second belt 27 to move, thereby changing the distance between the second belt 27 and the end of the first conical column 25 and the second conical column 26, further changing the transmission ratio between the first conical column 25 and the second conical column 26, so as to change the rotation speed of the second conical column 26. At this time, if the rotation speed of the first conical column 25 is normal, the rotation speed of the rotary blade 5 is also normal. Secondly, if the moisture content of the soil inside the saline-alkali land is low, it means that the saline-alkali land is short of water and the soil is severely compacted. Because the reduction of moisture in the soil will reduce the electrical conductivity, the current passing through the two probes 9 and the electromagnet 14 is small, and the electromagnet 14 produces less magnetism. Further, the electromagnet 14 will cause the slider 12 of the magnetic material to move a short distance toward the electromagnet 14. In summary, the ball valve 34 is opened to a greater extent, which improves the water supply. The second conical column 26 drives the rotary blade 5 to rotate faster. Since the moisture content of the saline-alkali land is low, the ball valve 34 can be opened to a greater extent to irrigate the soil appropriately, thereby avoiding soil drought. In addition, since the saline-alkali land is short of water and the soil is severely compacted, the rotary blade 5 rotates faster. The increase in the speed of the rotary blade 5 can effectively break and loosen the compacted soil, enhance the air permeability and water permeability of the soil, and the soil loosening effect helps to improve the penetration capacity of irrigation water, ensure that water can penetrate into the soil, and avoid the irrigation water being blocked by the compacted soil on the surface, thereby improving the overall irrigation effect and the water utilization rate of the soil. Third, if the soil moisture content inside the saline-alkali land is high, the current passing through the two probes 9 and the electromagnet 14 is large, and the electromagnet 14 generates a small magnetism. Further, the electromagnet 14 causes the slider 12 of the magnetic material to move a long distance toward the electromagnet 14. In summary, the opening degree of the ball valve 34 becomes smaller, and the second conical column 26 drives the rotation speed of the rotary blade 5 to slow down. Since the soil moisture content of the saline-alkali land is high, the ball valve 34 can be opened less to irrigate the soil appropriately, thereby avoiding soil flooding. In addition, since the soil in the saline-alkali land has a high moisture content and is not severely compacted, the rotation speed of the rotary blade 5 is slowed down to prevent the soil from being broken into smaller pieces, resulting in poor drainage and poor aeration, thereby avoiding the excessively fine soil from hindering the irrigation effect of the soil. In summary, when irrigating saline-alkali soil, the irrigation water output and the rotation speed of the rotary tiller 5 can be adjusted in real time, avoiding drought and flooding and soil compaction and excessive fineness during irrigation, thereby improving the use effect of the equipment.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
