いる。Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are a plan view showing an example of an embodiment of a two-shaft shearing crusher according to the present invention, and an enlarged sectional view taken along line II-II in FIG. 1 in the figure is the bottom 1
a is a rectangular box-shaped casing in which a number of slits 2 covering substantially the entire width in the width direction (the left-right direction in FIG. 2) are provided in parallel in the depth direction (the left-right direction in FIG. 1) as appropriate. The casing 1 is mounted on a gantry 3 having a conveyor (not shown) for carrying out crushed products. On the bottom 1a of the casing 1, two shafts 4 are respectively arranged in parallel with each other at a right angle to the slit 2 through a plurality of bearing brackets 5, and a gear box (FIG. (Not shown) or a driving device such as a hydraulic motor 6 so as to be rotatable forward and backward in different directions. A fixed blade 7 for shearing and crushing the waste in cooperation with a rotary blade described later is mounted on the side surface of each slit 2 at the bottom 1a of the casing 1 so as to be located between the two shafts 4. On the other hand, the two shafts 4 have a plurality of U-shaped edges 8a, 8b, 8c (two in the normal rotation direction (arrow A direction in FIG. 2) and one in the reverse rotation direction) opened in the rotation direction of the shaft 4. The rotating blades 8 having a semicircular shape are attached to the slits 2 in a phase-shifted manner via flanges 9 attached to the shafts 4 so as to correspond to the slits 2, and the peripheral edges of the rotating blades 8 are spaced apart by a small distance between the shafts 4. Further, one side surface is brought into sliding contact with the side surface of each fixed blade 7. Below the fixed blade 7, a baffle plate 11 having a trapezoidal cross section extending parallel to the axis 4 is provided.
The casing 1 is appropriately spaced from the bottom 1 a of the casing 1.

Is transported between the two shafts 4 while being bent and torn, and is also sheared and crushed in cooperation with the fixed blade 7, falls as a crushed product from the slit 2 in the bottom 1 a, and is conveyed to the gantry 3. Is carried out of the machine. When the rotary blade 8 is overloaded during the above-described waste crushing treatment, the waste is moved to the inner surface side of the casing 1 by the reverse rotation of the shaft 4. As shown in FIG. 3, when the edges 8a, 8b, 8c of the rotary blade 8 are located on the inner side of the casing 1 and the slit 2 is opened, a rod-like waste or semi-crushed product W of about 1 m is opened. Although but when you Surinukeyo slit 2, is deter falling by horizontal <br/> baffle 11, are crushed by the rotary blade 8 that rotates along with the forward rotation of the continue come axis 4 and the fixed blade 7 Broken
The crushed product falls along the inclined surface of the baffle plate 11 and falls.
By 3 of the conveyor Ru der shall be carried out to the outside of the machine.
