[0005] Furthermore, the driving wheel group includes a first driving wheel fixed at both ends of the first C-shaped steel track, a first fixed pulley group composed of a first fixed pulley and a fourth fixed pulley stacked together, a second driving wheel fixed at both ends of the third C-shaped steel track, a second fixed pulley group composed of a second fixed pulley and a third fixed pulley stacked together, a first movable pulley arranged along the first C-shaped steel track, and a second movable pulley arranged along the third C-shaped steel track.

[0006] Furthermore, the driving rope includes a first driving rope and a second driving rope. The first driving rope passes around the first driving wheel and then turns through the first fixed pulley in the fixed pulley group, and then is connected to the second fixed pulley. After turning through the second movable pulley, it is connected to the first connecting end of the spraying joint. The first driving rope passes around the first movable pulley through the third connecting end of the spraying joint, and then is connected back to the first driving wheel after turning through the first movable pulley; the second driving rope passes around the second driving wheel and then turns through the second movable pulley, and then is connected to the fourth connecting end of the spraying joint; the second driving rope passes around the first movable pulley through the second connecting end of the spraying joint, and then turns through the third fixed pulley in the fixed pulley group, and then is connected to the fourth fixed pulley in the fixed pulleys.

At the same time, since the driving rope is used to drive the spray head to move, the device is lighter and has a lower cost. The spray head can move arbitrarily in the plane, and automatic spraying can be achieved. Compared with the traditional hanging sprayer, it can be used while moving in the inner heat preservation greenhouse. The sprayer has a simple structure, low cost, and is easy to maintain and repair. It can achieve full automatic control, improve work efficiency, and save labor. BRIEF DESCRIPTION OF THE DRAWINGS
