The invention discloses a landscaping device, comprising a pull rod, an outer box and a base, the top of the base is provided with the outer box, the top of the outer box is provided with a battery board mounting seat, the battery board mounting seat is provided with a solar cell panel assembly, a display is arranged at the central portion of the side wall of the outer box, and the pull rod is fixed on the base below the display. The output end of a second motor drives a driving gear on an output shaft to rotate, and because a half axle gear at one end of each of two water pipes is engaged with the driving gear, the water pipes rotate to a horizontal position to enlarge the spray area of a chemical liquid, and a worker can complete chemical liquid spraying of a large range only by pullingthe device to move, also the spraying is even and normal effect of the chemical liquid is guaranteed. At the same time, a second electromagnetic throttle valve is utilized to control the flow rate ofthe chemical liquid to avoid excessive spraying of the chemical liquid, and when the chemical liquid is not required to be sprayed, by controlling the second motor to reverse, the two water pipes areplaced in a vertical direction, and thus the occupied volume is reduced and storage is easy.
