At this time, the tension spring 18 rebounds and contracts, so that the second fixing frame 17 pushes the piston block 28 to move downward through the fixing rod 27, so that the water in the slide cylinder 25 is discharged, and the other side of the slide cylinder 25 is connected to and fixed with a water outlet pipe 33, and one end of the water outlet pipe 33 is connected to and fixed with a hose 34.

The bottom ends of the two slide plates 9 are rotatably connected with a rotating block 10, and one end of the rotating block 10 is fixed with a protrusion 13 by a bolt. The turf roll is placed on the ground, and a gap is left in the middle of the turf roll, and the two protrusions 13 correspond to the gaps generated at the two ends of the turf roll. The motor rotates to make the screw slide plate 9 move toward the middle respectively until the slide plate 9 contacts and clamps the turf roll, and the protrusions 13 are inserted into the gaps at the two ends of the turf roll, so that the turf roll is positioned.

[0038] It should be noted that the pushing component includes two synchronous pulleys 24, which are respectively keyed to the two ends of the rotating shaft. The top outer wall of the electric vehicle 3 is fixed with two fixed plates 20 by bolts. One side of the two fixed plates 20 is rotatably connected with a connecting shaft. The outer side of the connecting shaft is keyed to the first pulley, and a synchronous belt 21 is wound around the first pulley and the synchronous pulley 24. One end of the connecting shaft passes through the fixed plate 20 and is fixed with a cam 19 by bolts. The rotation of the rotating shaft causes the synchronous pulley 24 to rotate, and the synchronous pulley 24 drives the gear 5 to rotate through the synchronous belt 21, so that the cam 19 pushes the second fixed frame 17 to move upward. At this time, there is a gap between the second fixed frame 17 and the slide cylinder 25. The power component includes two toothed discs 7, which are respectively keyed to the two ends of the rotating shaft. Both ends of the connecting pipe are keyed to the gear 5, and the gear 5 is meshed with the toothed disc 7. Both ends of the water spray pipe 22 pass through the support plate 6 and are sleeved with a torsion spring 23, and both ends of the torsion spring 23 The ends are fixed to the water spray pipe 22 and the support plate 6 respectively, and the rotation of the rotating shaft causes the toothed disc 7 to intermittently drive the gear 5 to rotate, and with the use of the torsion spring 23, the water spray pipe 22 drives the nozzle 32 to swing back and forth to spray water.

When the electric vehicle 3 moves, the turf roll rotates and is laid on the ground. As the thickness of the turf roll decreases, under the action of the first fixed frame 12 and the turf roll's own gravity, the slide bar 16 slides downward, so that the turf roll is always in contact with the ground during the laying process. At the same time, as the electric vehicle 3 moves, the pressure roller 8 follows it to press the turf on the ground. At this time, the pressure roller 8 rotates, so that the rotating shaft drives the synchronous pulley 24 and the gap The toothed disc 7 rotates, and the synchronous pulley 24 drives the gear 5 to rotate through the synchronous belt 21, so that the cam 19 pushes the second fixed frame 17 to move upward, and the telescopic rod 26 extends, the tension spring 18 extends, and then the fixed rod 27 pulls the piston block 28 to move upward, so that the water in the water tank 4 enters the slide cylinder 25 through the water inlet pipe 29, and then the cam 19 continues to rotate to separate it from the second fixed frame 17. At this time, the tension spring 18 rebounds and contracts, so that the second fixed frame 17 pushes the piston block 28 to move downward through the fixed rod 27, and then the water in the slide cylinder 25 enters the water spray pipe 22 through the water outlet pipe 33 and the hose 34, and finally sprays it onto the ground through the nozzle 32. At the same time, the rotation of the rotating shaft causes the toothed disc 7 to intermittently drive the gear 5 to rotate, and cooperates with the use of the torsion spring 23, so that the water spray pipe 22 drives the nozzle 32 to swing back and forth to spray water.

[0040] A method for laying vegetation on bare soil at the base of a power transmission line in an ecologically fragile area comprises the following steps:

9. A method for laying vegetation on bare soil at the tower foundation of a power transmission line in an ecologically fragile area, characterized in that: The following steps are involved: S1: First, place the turf roll on the ground, leaving a gap in the middle of the turf roll, and make the two protrusions (13) correspond to the gaps at the two ends of the turf roll, start the motor, and the motor rotates to make the screw slide plate (9) move toward the middle respectively until the slide plate (9) contacts and clamps the turf roll, and at the same time, the protrusions (13) are inserted into the gaps at the two ends of the turf roll, so that the turf roll is positioned; S2: the electric vehicle (3) moves, the turf roll rotates and is laid on the ground, and as the thickness of the turf roll decreases, the slide bar (16) slides downward under the action of the first fixed frame (12) and the gravity of the turf roll, so that the turf roll is always in contact with the ground during the laying process; S3: As the electric vehicle (3) moves, the pressing roller (8) rotates along with it and presses the grass on the ground; S4: At the same time, the pressure roller (8) rotates to drive the rotating shaft to drive the synchronous pulley (24) and the toothed disc (7) to rotate, and the synchronous pulley (24) drives the gear (5) to rotate through the synchronous belt (21), so that the cam (19) pushes the second fixed frame (17) to move upward, and the telescopic rod (26) is extended, and the tension spring (18) is extended, so that the fixed rod (27) pulls the piston block (28) to move upward, so that the water in the water tank (4) enters the slide cylinder (25) through the water inlet pipe (29), and then the cam (19) continues to rotate to separate from the second fixed frame (17), at this time the tension spring (18) rebounds and contracts, so that the second fixed frame (17) pushes the piston block (28) to move downward through the fixed rod (27), and then the water in the slide cylinder (25) enters the water spray pipe (22) through the water outlet pipe (33) and the hose (34), and finally sprays out to the ground through the nozzle (32); S5: At the same time, the rotating shaft rotates to make the toothless disc (7) intermittently drive the gear (5) to rotate, and cooperate with the use of the torsion spring (23), so that the water spray pipe (22) drives the spray head (32) to swing back and forth to spray water; S6: This cycle is repeated to achieve laying, watering and compacting of the turf.
