PROBLEM TO BE SOLVED: To provide a sieve disintegrator with a simple structure as much as possible to enable a reduction in manufacturing costs, as well as running costs.SOLUTION: A sieve disintegrator 1 is provided, comprising: a hopper 2 a disintegration mechanism 3 disposed in the hopper 2, and provided with a plurality of disintegration members 12 to a supporting shaft 11 and a driving mechanism 4 for the disintegration mechanism to drive the disintegration mechanism 3. An aperture is formed as a grain body exhaust port 6 at the lower end part of the hopper 2, a sieve member 7 is disposed to the grain body exhaust port 6, and a foreign object exhaust port 9 is bored at the lower end part of the left wall section. The disintegration mechanism 3 comprises the supporting shaft 11, and the plurality of the disintegration members 12 fixed to the supporting shaft 11. The disintegration members 12 are disposed at a predetermined interval in the axial direction of the supporting shaft 11, and are disposed at a predetermined angle θ in the circumferential direction of the supporting shaft 11.COPYRIGHT: (C)2014,JPO&INPIT【課題】 篩解砕装置の構成を極力簡単にして、製造コストを低減すると共に、ランニングコストも低減できる篩解砕装置を提供する。【解決手段】 ホッパー2と、このホッパー2内に配設され、支持軸11に複数の解砕部材12を配設した解砕機構3と、この解砕機構3を駆動する解砕機構駆動機構4と、から篩解砕装置1を構成する。ホッパー2の下端に開口して粒体排出口6を形成し、この粒体排出口6に篩部材7を配設し、左側壁部の下端部には異物排出口9を穿設する。解砕機構3は、支持軸11と、これに固定した複数の解砕部材12とから成り、解砕部材12は、支持軸11の軸方向に所定間隔で配置してあり、かつ、支持軸11の周方向に所定角度θで配置する。【選択図】 図2
