<p>The present invention relates to a collection chute supporting structure and a combined metering device. In the collection chute supporting structure, a plate which forms a polygonal annular shape form a plane shape of a supporting frame. The cross section shape of each edge of the polygon forms an approximate reverse-J-shaped member which is provided with a downwards open bending part at the upper end. Furthermore each top of the polygon forms a flat longitudinal wall shape which is not provided with a bent part.</p> |
