Abstract
The object of the present invention is to provide a crusher, which is capable of efficiently crushing materials or scraps, and a crushing mechanism for the crusher. To achieve the object, the crusher of the present invention comprises: a fixed member having a first blade portion for crushing a material to be crushed into pieces; a movable member being capable of moving to and away from the fixed member, the movable member having a second blade portion, which crushes the material into pieces with the first blade portion when the movable member is moved toward the fixed member; and a driving mechanism for moving the movable member to and away from the fixed member.
Claims11
A crusher, comprising:
- a fixed member having a first blade portion for crushing a material to be crushed into pieces;
- a movable member being capable of moving to and away from said fixed member, said movable member having a second blade portion, which crushes the material into pieces with said first blade portion when said movable member is moved toward said fixed member;
- a driving mechanism for moving said movable member to and away from said fixed member;
- and
- a preparatory crushing section which includes a rotary blade member, wherein the material is preparatorily crushed by said preparatory crushing section and introduced to said fixed member and said movable member.
A crusher, comprising:
- a fixed member having a first blade portion for crushing a material to be crushed into pieces;
- a movable member being capable of moving to and away from said fixed member, said movable member having a second blade portion, which crushes the material into pieces with said first blade portion when said movable member is moved toward said fixed member;
- a driving mechanism for moving said movable member to and away from said fixed member;
- said first blade portion including:
- a first shearing section for primarily shearing the material;
- and
- a second shearing section for secondarily shearing the material;
- which has been primarily sheared, and
- said second blade portion including:
- a third shearing section, which primarily shears the material with said first shearing section when said movable member is moved toward said fixed member;
- and
- a fourth shearing section, which secondarily shears the material with said second shearing section when said movable member is further moved toward said fixed member and as said third shearing section is moved away from said first shearing section.
A crushing mechanism, comprising:
- a first member;
- a second member capable of moving to and away from said first member;
- a first shearing section having a plurality of groove-blades, which are formed with parts of an edge of said first member and side sections of a plurality of projected sections, which are projected from the edge thereof;
- a second shearing section having a plurality of concave sections, which are formed in fixed end portions of the projected sections;
- a third shearing section having a plurality of projected blades, which are arranged in said second member so as to engage with the groove-blades of said first shearing section;
- and
- a fourth shearing section having a plurality of projections, which are arranged in said second member so as to fit into the concave sections of said second shearing section.
