[0026] A method for watering a municipal engineering greening watering system, the method comprising the following steps: Step A: before using the system, pour the nutrient solution to be sprayed into a storage tank 5, add water for watering into a water storage tank 4, control the left and right movement of a telescopic rod 210 by driving a motor 201, and realize the movement of a large rack 214 and a small rack 222 in different directions by a meshing connection relationship between two gears, thereby adjusting the flow rate of the storage tank 5 and the water storage tank 4 to control the mixing ratio of water and nutrient solution; Step B: After placing the irrigation device at the irrigation starting point, the operation is started. The mixed liquid in the water storage tank 6 is pumped into the hose 108 through the water pipe 9 wound outside the cylinder 8 by the water pump, and the greening is irrigated by the control button above the telescopic tube 109; Step C: The servo motor 101 is used to control the lifting of the rectangular long plate 106 to change the watering distance. At the same time, the lifting of the rectangular long plate 106 drives the lifting of the second piston rod 117 to control the lifting of the long strip plate 114, thereby changing the watering angle.

[0027] Furthermore, when watering the greening in step C, the watering angle is effectively changed by lifting and lowering the first sleeve 112. The water pipe 9 and the hose 108 are both made of non-toxic and environmentally friendly rubber. When the rectangular long plate 106 controls the descent of the second piston rod 117, the second piston rod 117 transports the liquid inside the hydraulic cylinder 118 to the inside of the first sleeve 112 through the hose set between the hydraulic cylinder 118 and the first sleeve 112, so that the first piston rod 113 rises. When the rectangular long plate 106 rises to the highest point, the first piston rod 113 slides inside the first sleeve 112.

[0028] Working principle: Before using the system, pour the nutrient solution to be sprayed into the storage tank 5, add the irrigation water into the water storage tank 4, start the driving motor 201, the driving motor 201 rotates to drive the rotating shaft 202 fixedly connected to the output end to rotate, the rotating shaft 202 drives the disc 203 to rotate, the disc 203 drives the protrusion 204 fixedly connected to its left end to rotate around the center of the disc 203, and then drives the cross rod 205 slidably connected to the outer surface of the protrusion 204 to achieve horizontal reciprocating motion; When the cross bar 205 moves from front to back, the cross bar 205 drives the telescopic rod 210 to move backward through the first connecting rod 206, and also drives the rectangular block 211 fixedly connected to the front end of the telescopic rod 210 to move backward. The first driving gear 213 above the rectangular block 211 drives the first driven gear 215 to rotate through the meshing connection relationship between the two gears, so that the internal valve of the first switch valve 216 is gradually closed, thereby reducing the speed of the water flowing into the storage tank 6 from the storage tank 5; At the same time, the second driving gear 221 above the rectangular block 211 rotates in the opposite direction to the first driving gear 213, and drives the second driven gear 223 to rotate through the meshing connection between the two gears, so that the internal valve of the second driven gear 223 is gradually opened, thereby increasing the speed of the water storage tank 4 flowing into the water storage tank 6, thereby adjusting the flow rate of the storage tank 5 and the water storage tank 4 entering the water storage tank 6 to control the mixing ratio of water and nutrient solution; Then, the mixed liquid in the water tank 6 is pumped into the hose 108 through the water pipe 9 wound around the outside of the cylinder 8 by the water pump on the right side of the water tank 6, and the greenery is irrigated by the control button above the telescopic tube 109; At this time, the servo motor 101 is started, and the output end of the servo motor 101 drives the rotating shaft 102 to rotate, and drives the first connecting rod 103 fixedly connected to one end of the rotating shaft 102 to rotate around the rotating shaft 102, thereby controlling the lifting and lowering of the rectangular long plate 106; to change the watering distance, when the rectangular long plate 106 slowly rises from the bottom, the second piston rod 117 on the right side of the rectangular long plate 106 also rises with the cylindrical platform 116. At this time, the second piston rod 117 will no longer squeeze the hydraulic cylinder 118, so that the liquid inside the connecting pipe set between the hydraulic cylinder 118 and the first sleeve 112 flows into the hydraulic cylinder 118. At this time, due to the first There is nothing supporting the first piston rod 113 inside the sleeve 112, causing the first piston rod 113 to slowly descend, so that the long plate 114 drives the telescopic tube 109 at the top to swing downward around the hose 108 at the connection point of the telescopic tube 109, thereby watering the greenery close to the system; when the rectangular long plate 106 slowly descends from the top, the second piston rod 117 will compress the hydraulic cylinder 118, causing the liquid inside the hydraulic cylinder 118 to flow into the first sleeve 112, and then slowly cause the first piston rod 113 to rise, at which time the telescopic tube 109 will swing upward, thereby watering the greenery far from the system.
