<p>PURPOSE:To simply perform pipe arrangement between a pneumatic type drive apparatus and a dust collector casing in a min. space, by using the support shaft of a hinge for supporting an access door in a freely openable and closable manner as a connecting pipe. CONSTITUTION:A support shaft 9 is formed to the center of a hinge 7 of which one piece is secured to the pillar 8 of a dust collector casing and the other piece is secured to an access door 5 as a hollow sahft and the end parts thereof are protruded from the hinge 7. In addition the pipe 11 of a pneumatic type drive apparatus 10 for opening and closing a movable door 6 is attached to one end of the support shaft 9 of the hinge 7 through an elbow 12. By this mechanism, there is no obstacle in access to a dust collecting unit and pipe arrangement becomes short and the space thereof becomes small.</p> |
