[0023] A lawn care device for garden construction comprises an outer shell 1, a water tank 2 is arranged in the outer shell 1, a driving motor 3 is installed on one side of the top of the water tank 2, a reciprocating swinging structure is arranged on the upper part of the outer shell 1, the reciprocating swinging structure is connected to the water tank 2, the reciprocating swinging structure comprises a first connecting rod 4, a second connecting rod 5 and a third connecting rod 6, an output shaft 7 of the driving motor 3 passes through the outer shell 1 and is fixedly connected to one end of the first connecting rod 4, the other end of the first connecting rod 4 is rotatably connected to one end of the second connecting rod 5, the other end of the second connecting rod 5 is rotatably connected to the middle position of the third connecting rod 6, and the end of the third connecting rod 6 close to the outer shell 1 is rotatably connected to the outer shell 1 through a rotating shaft 8; the length of the first connecting rod 4 is less than the lengths of the second connecting rod 5 and the third connecting rod 6.

[0024] Specifically, the drive motor 3 is started to make the output shaft 7 drive the first link 4 to rotate. When the first link 4 rotates in a direction away from the third link 6, the first link 4 pulls the third link 6 to rotate a certain angle in the direction of the first link 4 through the second link 5. When the first link 4 rotates in a direction close to the third link 6, the first link 4 pushes the third link 6 to rotate a certain angle in the direction away from the first link 4 through the second link 5. The rotation of the first link 4 drives the third link 6 to swing back and forth around the rotating shaft 8, so that the watering nozzle 10 at the top of the third link 6 swings back and forth, so as to water and maintain the lawn in the forward direction of the outer shell 1 and on its left and right sides.

[0025] An irrigation nozzle 10 is provided at one end of the third connecting rod 6 away from the outer shell 1. The interior of the third connecting rod 6 is a hollow structure. A water supply hose 9 runs through the third connecting rod 6. One side of the water supply hose 9 runs through the third connecting rod 6 and the outer shell 1 and is connected to the water tank 2. The other side of the water supply hose 9 is connected to the irrigation nozzle 10. A water pump is provided in the water tank 2. The water source is transported to the irrigation nozzle 10 through the water supply hose 9 through the water pump; a plurality of water distribution pipes 15 are provided in the irrigation nozzle 10. The water distribution pipes 15 are radially distributed and connected to the water supply hose 9. The water source sprayed out through the water distribution pipes 15 is radial, so that the coverage of lawn irrigation is wider.

[0026] A water inlet 11 is provided in the middle of the outer shell 1 , and the water inlet 11 is connected to the top surface of the water tank 2 via an input pipe 12 , and water can be added to the water tank 2 via the water inlet 11 and the input pipe 12 .
