摘要： PROBLEM TO BE SOLVED: To provide a crusher which easily crushes a concrete structure and has a prolonged life time of a crushing member. SOLUTION: This concrete crusher comprises: a pair of crushing members 1 and 1 which are provided with crushing blades 5 and 5 on inner surfaces opposed to each other; a frame 3 to support the crushing members 1 and 1 so that they are opened, closed and turned; and a hydraulic cylinder 4 to open, close and turn the crushing members 1 and 1. As for the side shape or the cross section shape of the crushing blade 5, blade surfaces 5b and 5b are each formed in the shape of a convex surface from the shape of a concave curve to form an arrowhead shape so that compressive force is intense in an early stage of crushing and wedge force excels gradually in order to improve crushing efficiency to a material to be crushed W.

摘要： PROBLEM TO BE SOLVED: To efficiently erase a white line by providing a rotary brush inside the main body mounted at the front part of a vehicle and providing a nozzle for ejecting high-temperature and high-pressure water toward a white line erasing working part and a vacuum hose absorbing peeled pieces of white line paint together with fog-like moisture. SOLUTION: In order to erase a white line, after driving an engine 12 and packing fresh water into a fresh water tank 6, this device travels to an erasing starting position to rotate a rotary brush. In addition, the high-temperature and high-pressure water is ejected and the main body 2 is lowered to start working. Thereby, the brush 3 is rotated around a horizontal shaft to rub off white line paint by intruding the tips of bristles to the neighborhood of the base of fibers implanted on the substrate of artificial lawn, softens the paint by the heating action of water from the nozzle 4 at the same time and peels the paint from the fiber with water pressure. Then the peeled pieces of the white line paint are absorb and removed to the vacuum hose 5 together with the fog-like moisture reflected from the artificial lawn and recovered into a recovered water tank 11.
