Document Type and Number:
Japanese Patent JP3458074
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a crushing device which is of such a construction that small and uniform-size crushed pieces can be obtained without sorting the pieces out by a sieve.
SOLUTION: In the crushing device which crushes a material to be crushed such as a wood while crushed pieces are stirred by rotary crushing means 4, 5 housed in an enclosure 3, a sieving member 22 which prevents the crushed pieces of a larger size than specified from passing through, is provided on the discharge aperture side of the rotary crushing means 4, 5. Especially the sieving member has a freely expandable/contractable sieve mesh for making the size of the crushed piece to be discharged adjustable. In concrete terms, the sieving member comprises a pair of porous plates 23, 25, superposed over each other in a freely slidable manner, the pores of which are mutually deviated to expand and contract the sieve mesh. In addition, the sieving member is freely attachable to and detachable from the arm of a hydraulic arm.
