Note that both crushing rollers 5.6 rotate in the direction of biting the supplied coarse material as shown by arrows Aa and Ab. Therefore, the feeding direction by the screw is reversed, and each crushing blade 1
1.12 forms a rake angle θ in the feeding direction Ba and Bb as shown in FIG.

In the figure, reference numerals 13 and 14 are return blades provided on the crushing rollers 5 and 6, respectively, and these are small, dovetail blades formed in the shape of a screw in the opposite direction to the screws of the crushing blades 11 and 12. .14 are provided in opposite positions. Reference numeral 15 denotes a notch provided in the crushing blade 12, which is provided as necessary to catch the coarse material being fed and to effectively feed the material.

The lower crushing roller 7 has a grid 18 formed by two screw-shaped crushing blades 16 and 17 with different pitches, and the length and width of the crushed material is regulated by the size of the grid 220 and rotational speed. It is.

Further, a counter knife 20 is provided facing the discharge side of the lower crushing roller 7, and among the coarse materials crushed and sent out by the upper and lower crushing rollers 5.6, those stored in the square 18 are Although they are allowed to be sent out, those that protrude beyond the first day of the square are crushed by the counter knife 20.

Note that reference numeral 21 denotes an auxiliary guide, which is provided on the opposite side of the lower crushing roller 7 from the counter knife 20, and assists the coarse material following the upper crushing roller 6 to return upward with the roller 6. It is something.

In the figure, 22 is a container for transporting crushed materials, and 23.24
．． Reference numeral 25 denotes a hydraulic motor for each of the crushing rollers 5, 6, 7, which are rotated at appropriate rotational speeds as will be described later.

The storage tank 4 is equipped with a pushing mechanism 30 that pushes the crushed material wb into the tank, facing the conveyor 22 for carrying out. A well-known structure can be applied to this push-in structure 30, and the figure shows one example thereof. That is, the pushing mechanism 30 has its upper end pivotally supported in a proper position, and a press plate 33 is pivotally supported at the tip of a swinging arm 31 that is swung by a first hydraulic cylinder 32. A second hydraulic cylinder 34 is provided. As a result, the press plate 33 is connected to the discharge side of the container 22, and the press plate 33 is connected to the discharge side of the container 22.
