[0006] When in use, the wiper combination switch controls the high-speed and low-speed operation of the front wiper through the high-speed and low-speed relays, and the wiper combination switch controls the washing pot to spray water on the glass; the wiper combination switch controls the intermittent operation of the front wiper through the wiper intermittent relay. The side wiper switch controls the high-speed and low-speed operation of the side wiper. The front and right side glass of the construction machinery can be cleaned, which is beneficial to improve the driver's field of vision.

[0007] Preferably, the washing pot is installed on the front side and the right side of the cab.

[0008] When in use, the wiper combination switch controls the washer pot to spray water forward and on the right side of the glass.

[0009] In summary, the beneficial effects of the utility model are as follows: when in use, the wiper combination switch controls the high-speed and low-speed actions of the front wiper through the high-speed and low-speed relays, and the wiper combination switch controls the washing pot to spray water onto the glass; the wiper combination switch controls the intermittent action of the front wiper through the wiper intermittent relay. The side wiper switch controls the high-speed and low-speed operation of the side wiper. The front side glass and the right side glass of the engineering machinery can be cleaned, which is beneficial to improving the driver's field of vision. BRIEF DESCRIPTION OF THE DRAWINGS
