PURPOSE: An air cleaning system of construction equipment is provided to keep a core of a cooling module and an insect-proof net clean by cleaning foreign materials on the same, to easily maintain equipment, and to maintain the cooling performance of the equipment in a best condition. CONSTITUTION: An air cleaning system of construction equipment comprises an air pump, an air tube(14), a pair of cylinders(15), a driving motor(16), and a controlling unit. The air tube is installed to be lifted up and down and rotated in between a cooling module(11) and an insect-proof net(12). The air tube is connected to the air pump and eliminates foreign materials on a core of the cooling module and the insect-proof net by using pneumatic being discharged through a nozzle(13). Each one end of the cylinders is connected to the outer side surface of the cooling module to be rotated and each the other end of the cylinders are connected to both ends of the air tube. The cylinders lift up and down the air tube between the cooling module and the insect-proof net. The driving motor is mounted in the cylinder and rotates the air tube. The controlling unit outputs control signals for driving the air pump, the cylinders, and the driving motor in order to eliminate foreign materials on the core of the cooling module and the insect-proof net. |
