Device for immobilising the chute on the ends of journals in an apparatus for loading a shaft furnace

The invention relates to a device for immobilising the chute on the ends of journals in an apparatus for loading a shaft furnace, comprising a pivotable chute (1) for distributing material, the chute being connected to support journals (2) by means of tabs (11) which are inserted into recesses (21) arranged on the journals and which are immobilised thereon by means of pins (3) comprising an eccentric nipple (31) at the end thereof which is inserted in a lug of the chute in order to keep the lug immobilised at the bottom of the recess thereof, and locking means (4) for rotationally locking the chute. Each chute comprises, at the outer end thereof opposite the nipple, means (32) for rotational adjustment and for clamping in order to be able to press the nipple onto the lug of the chute using sufficient force by means of rotating the pin, and the locking means comprising an indexing plate (41) which is rotatably connected to the end of the pin (3), the plate (41) further comprising teeth (416) which are arranged
