PURPOSE:The cross section of the opening for dust removal is rapidly expanded vertically and/or lengthwise from the inlet toward the trash box to inhibit the suction of trash from the trash box to the spinning rotor. CONSTITUTION:The distances H1 and H2 between the upper and lower faces of the opening for trash removal and the upper and lower faces of the trash box, respectively are set so that they satisfy the equations: 0.1H0<=H1, H2<=0.6H0 where H0 is the vertical height of the opening for the dust removal and equations: 0.05W0<=W1, W2<=0.25W0 where W1 and W2 are the distances between the fore and back walls at the inlet of the dust-removal opening and the fore and back walls of the opening for dust removal and W0 is the width between fore and back faces at the inlet of the dust-removal opening. The flows of air suction 14 and 15 are separated from the flying trace of the trash to reduce the suction of trash into the rotor. |
