[0041] It is worth emphasizing that the sprinkler mechanism 7 also includes a protection box 714 fixed on the surface of one of the fixed plates 71 away from the screw 73, the sprinkler motor 712 is located inside the protection box 714, the rotating shaft 713 passes through the outer wall of the protection box 714 away from the screw 73, a protection tube 9 is fixed on the top surface of the working plate 1, the cylinder body of the electric cylinder 4 is located inside the protection tube 9, and the loosening mechanism 3 also includes a motor box 35 fixed on the outer wall of one of the vertical plate ends of the frame 2 away from the loosening roller 32, and the loosening motor 34 is located inside the motor box 35, which can protect the sprinkler motor 712, the electric cylinder 4 and the loosening motor 34, thereby extending the service life of the sprinkler motor 712, the electric cylinder 4 and the loosening motor 34.

[0042] Finally, it should be noted that the electric cylinder 4, water pump 10, sprinkler motor 712, loosening motor 34 and other components involved in the utility model are all universal standard parts or components known to technical personnel in this field, and their structures and principles are all known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and compatible controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the utility model. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0043] In the specific use of this embodiment, when it is necessary to loosen the soil in the citrus planting area, first, the entire device is connected to the external tractor through two traction rods 6, and then the electric cylinder 4 is started through the external PLC. The piston rod movement of the electric cylinder 4 drives the frame 2 fixed with it through the gasket 8 to move downward, and the movement of the frame 2 drives the loosening mechanism 3 to move downward, thereby driving a number of loosening knives 33 to move downward. When the depth of the several loosening knives 33 inserted into the soil is appropriate, the electric cylinder 4 is closed by the external PLC, and then a proper amount of water is added to the inside of the water supply tank 5 through the water inlet hole on the top surface of the water supply tank 5, and then the rubber plug 13 is covered. Then, the loosening motor 34, the sprinkler motor 712, the water pump 10 and the external tractor are started by the external PLC and the output shaft of the sprinkler motor 712 is controlled to rotate alternately forward and reverse. The output shaft of the loosening motor 34 rotates to drive the roller 31 coaxially connected to it to rotate, and the rotation of the roller 31 drives the loosening roller 32 coaxially fixed to it to rotate, and the rotation of the loosening roller 32 drives the several loosening knives 33 fixed to it to rotate;

[0044] At this time, the water pump 10 pumps the water in the water supply tank 5 into the water-passing hard pipe 11, and the water entering the water-passing hard pipe 11 then passes into the water-passing hose 12 and into the water inlet hard pipe 78. The water entering the water inlet hard pipe 78 then enters the water spray pipe 76 and passes into the water spray plate 77. The water entering the water spray plate 77 is then sprayed out by a plurality of water outlet holes on its outer wall. At the same time, the output shaft of the sprinkler motor 712 rotates to drive the rotating shaft 713 coaxially connected thereto to rotate, and the rotation of the rotating shaft 713 drives the same-side gear 711 coaxially fixed thereto to rotate, and the rotation of the gear 711 drives another gear 711 meshing therewith to rotate, and the rotation of the other gear 711 drives the rotating rod 710 fixed thereto to rotate, and the rotating rod 710 rotates The rotation of the rotating column 72 on the same side fixed with the same axis drives the rotation of the rotating column 72, and the rotation of the rotating column 72 drives the screw 73 fixed with the same axis to rotate. The rotation of the screw 73 drives the connecting rod 74 threadedly connected with it to move, and the movement of the connecting rod 74 drives the water passing box 75 fixed with it to move. The water passing box 75 moves under the guidance of the guide bar 79 and the guide groove on the top surface of the working plate 1. The movement of the water passing box 75 drives the water spray pipe 76 and the water spray plate 77 to move. Because the output shaft of the sprinkler motor 712 rotates alternately forward and reverse, it can drive the screw 73 to rotate alternately forward and reverse, thereby indirectly causing the connecting rod 74 to perform a linear reciprocating motion in the front-to-back direction, and then the water spray pipe 76 and the water spray plate 77 can be made to perform a linear reciprocating motion in the front-to-back direction;

[0045] After the external tractor is started, the whole device can be driven to move by the cooperation of a plurality of universal wheels 16. During the movement, the whole device can loosen and sprinkle the soil in the planting area.
