The invention belongs to the technical field of coal mine underground explosion-proof vehicle equipment and specifically relates to a pneumatically controlled linked windshield wiper water spraying system for a coal mine underground vehicle. The problem that an underground explosion-proof vehicle lacks an integrated water spraying pneumatic windshield wiper is solved. The pneumatically controlledlinked windshield wiper water spraying system for the coal mine underground vehicle comprises an air source, a manual button switching valve, a hydraulic operated directional valve, a pneumatically controlled water spraying pressure pump, a water storage tank, a water spraying rotating device, an air windshield wiper, a pneumatic pipeline and a high pressure water pipe. According to the pneumatically controlled linked windshield wiper water spraying system for the coal mine underground vehicle, the structure is simple, the driving is convenient, the placing is easy, the operability is strong,underground explosion-proof requirements are satisfied, the system is also environmentally friendly and suitable for all underground explosion-proof vehicles who need windshield wipers to wipe water,the failure rate of the electric windshield wiper is effectively reduced, the cost is saved in another form, and the safety performance of the vehicle is enhanced.
