DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for crushing excavated material supplied on a bar screen composed of straight rods and crushing and sending the excavated material.

[0002]

2. Description of the Related Art Conventionally, when a hard material such as stone is crushed on a sieve, the hard material is broken with a hammer or the like. Further, the viscous mass may be deposited on the sieve and not fall.

[0003]
