(1) Since the conventional plate glass crushing device 10 moves the rotating body 14 between the standby position and the crushing position, an elevating mechanism for the rotating body 14 is required, which complicates the equipment. (2) Further, since the crushing surface of the ribbon-shaped plate glass 20 crushed by the hammers 16, 16 ... becomes uneven, the crushing surface is cut linearly by the cutter device provided on the downstream side of the plate glass crushing device 10. There is a need to.

(3) Further, since the hammer 16 is fixed to the rotating body 14, if the hammer 16 wears, the rotating body 14 is replaced together with the hammer 16, so replacement of the hammer 16 is difficult. . In particular, this rotating body with a hammer is heavy in terms of its function, and in addition, because it is forced to be replaced on the belt conveyor, it is more difficult to replace it. (4) Further, since the cullets 21, 21 ... Crushed by the hammers 16, 16 ... are large, it is necessary to adjust the particle size of the cullet with a crusher before reusing the cullet when reusing the cullet.

(5) With the hammers 16 of the conventional plate glass crushing device 10, if the plate thickness of the plate glass 20 is 19 mm or more, the plate glass 20 cannot be crushed. The present invention has been made in view of such circumstances. (1) The structure for simplifying the structure is achieved by eliminating the rotating body lifting mechanism, and (2) the flat glass crushing device by crushing the crushing surface linearly. A cutter device installed on the downstream side of the glass plate is unnecessary, (3) Hammer can be easily replaced, (4) Crusher can be omitted, and (5) Plate glass with a plate thickness of 19 mm or more. It is an object of the present invention to provide a plate glass crushing device capable of crushing glass.
