枠１６は、上記掻き上げ装置２の支持枠（支持部）１７
および１８と、例えば自重によって着脱自在に嵌合固定
されている。As shown in FIGS. 1 and 3, the framework 12 extends along the upper surface 3 of the running section, and then includes a side frame 14 that rotates half a turn along the chain wheel 8, and a side frame 14 that fixes both ends of the side frame 14. It has a frame 15 and a T frame 16, and has an upper frame 15 and a T frame 16.
The frame 16 is a support frame (support part) 17 of the scraping device 2.
and 18, and are detachably fitted and fixed, for example, by their own weight.
向上記側枠１４の側面には手かり用の穴１９が穿設され
ている。A hole 19 for a clue is bored in the side surface of the side frame 14.
上記枠組１２に固定されたバースクリーン１３は、両端
を上記上枠１５および下枠１６に固定されたバー２０を
微細目間隔（たとえば数ミリ）で並列配置して形成され
ている。The bar screen 13 fixed to the framework 12 is formed by arranging bars 20, which have both ends fixed to the upper frame 15 and the lower frame 16, in parallel at minute intervals (for example, several millimeters).
そして隣設するバー２０の相互間には上記櫛歯１１が外
