Extractor for silo or similar, of the type comprising an extraction device 17 extending above the bottom 2 of the said silo and driving means, driven by a motor 13 to move the said extraction device 17 in such a way that, on the one hand, the latter forces the product contained in the silo through an opening 1 in the said bottom 2 in which are housed at least partly the said driving means and, on the other hand, such that the said extraction device 17 sweeps the said bottom 2, a deflector 9 covering the said opening 1 in order to prevent the direct flow of the said product through the latter. According to the invention, the said extractor is characterised in that it comprises a fixed vertical rod 4 supporting the said deflector 9 and serving as an axis of rotation for a coaxial sleeve 10 used in the transmission of movement between the said motor 13 and the said extraction device 17. <IMAGE>
