A lifting member 32 is connected between the chains 30 and 30 so as to connect them. An elevating member 34 is provided on the outside of the elevating member 32 and is movable in the vertical direction along the elevating member 32.
is embedded.

A frame-shaped body 38 located within a predetermined transfer path is coupled to the lifting member 34 via a support rod 36 . At the four corners of the upper surface of this frame-like body 38 are V-shaped support stands 40, 40, 40.
．． A container 42 is disposed within the frame-like body 38, and supports 44, 44, 44, 44 protruding outward from each of the four corners of the outer surface of the container 42 serve as supports 40.
．． 40.40.40. In addition, 46 is a discharge gate, which is provided to be able to open and close the lower end opening of the container 42.

The lifting member 34 is connected to a roller 48 which is also arranged above the chains 3o, 30. This roller 48 rolls on the guide rail IV50.
'50 is located above and along chain 30.30. In this guide tray/1750, a section 50a excluding the infeed side and the outfeed side of the weighing chain conveyor 20 is at a first height position, and a section 50b corresponding to the platform 26 of the chain weighing conveyor 20 is at a second height position. The section 50 (3
, 5od have a downward slope and an upward slope. The first height position is the frame-shaped body 3 on which the support 40 supports the support tool 44.
