Road surface construction is with self -cooling type crushing equipment

The utility model relates to a road surface construction is with self -cooling type crushing equipment, including frame, breaker, breaker set up the bottom in the frame, breaker include lift cylinder,rotating electrical machines, automatically cooling drill bit mechanism, connecting block, lift cylinder fixed mounting in frame bottom, lift cylinder's piston rod perpendicular to level ground setsup down, the top surface of connecting block be connected with the end of lift cylinder's piston rod, the rotating electrical machines pass through the mounting panel and install the bottom at the connecting block, the output shaft of automatically cooling drill bit mechanism and rotating electrical machines. This scheme messenger water flows into a core from the water inlet, and through core bit,finally from the delivery port outflow of core bit head, the heat that produces when directly taking away the drill bit operation reaches high -efficient effect of lowering the temperature. 本实用新型涉及种路面施工用自冷却型破碎设备，包括机架、破碎装置，所述的破
