Abstract

L'invention concerne un dispositif (101) de transfert de granulat, comportant une bouche (102) d'alimentation en granulat, une goulotte (103) de réception de granulat depuis la bouche, une vis (104) se trouvant dans la goulotte (103), la goulotte (103) ayant une paroi longitudinale (1030) s'étendant suivant un axe (1040) de rotation de la vis (104) et une sortie de granulat distante de la bouche (102) parallèlement à l'axe (1040) de rotation, la vis (104) comportant un filetage extérieur (1041) pour pouvoir déplacer, par rotation de la vis (104) autour de l'axe (1040) de rotation, le granulat dans la goulotte (103) le long de l'axe (1040) depuis la bouche (102) jusqu'à la sortie de granulat. L'invention est caractérisée en ce que le dispositif comporte un organe (105) de retenue au moins partielle du granulat, fixé à un support (106) fixe par rapport à la goulotte (103), s'étendant au moins en partie dans une section supérieure de la goulotte (103) et dans la course du filetage extérieur (1041) de la vis (104) et étant apte à s'incliner par butée contre le filetage extérieur (1041) lors de la rotation de la vis (104), ce qui permet d'obtenir une vis complètement chargée en amont et une vis partiellement chargée en aval.The invention relates to a device (101) for transferring aggregate, comprising a mouth (102) for feeding the aggregate, a chute (103) for receiving aggregate from the mouth, a screw (104) located in the chute ( 103), the chute (103) having a longitudinal wall (1030) extending along an axis (1040) of rotation of the screw (104) and an aggregate outlet distant from the mouth (102) parallel to the axis ( 1040) of rotation, the screw (104) having an external thread (1041) to be able to move, by rotation of the screw (104) around the axis (1040) of rotation, the aggregate in the chute (103) along of the axis (1040) from the mouth (102) to the aggregate outlet. The invention is characterized in that the device comprises a member (105) for at least partial retention of the aggregate, fixed to a support (106) fixed with respect to the chute (103), extending at least partly in a upper section of the chute (103) and in the stroke of the external thread (1041) of the screw (104) and being able to tilt against the external thread (1041) when rotating the screw (104) , which makes it possible to obtain a fully loaded screw upstream and a partially loaded screw downstream.
