PURPOSE:To heighten the efficiency of transporting a load by means of a scraper fixed to an endless chain by forming grooves for accommodating a vertical link and a horizontal link of the endless chain on the outer periphery of a driving roller. CONSTITUTION:Right and left two endless chains 4 formed by arranging oval links vertically and horizontally alternately to be connected to each other in such a manner as to meet at right angles are extended between driving rollers 2a and driven rollers disposed on both ends of a transport trough. Scrapers 5 are fixed to every plural vertical links 4a of both endless chains 4 that are opposite to each other. In this case, an annular hole 4' for accommodating one half part of the vertical link 4a of the endless chain 4 and an oval groove 4'' for accommodating the horizontal link are disposed on each outer peripheral surface of the driving rollers 2a. Thus, left and right endless chains 4 can be circulated in a body even at the time of one-sided loading, so that the scraper 5 can be prevented from tilting to keep back a load in the trough. |
