摘要： 1,067,737. Trimming and unloading silos; screw and endless conveyers. J. P. A. MARTIN Dec. 4, 1964 [Dec. 6, 1963], No. 49469/64. Headings B8A and B8E. A device for spreading grain in the cells of a silo or for discharging it therefrom comprises a scraping conveyer 8 mounted in a beam 4 which is movable vertically by a winch drum 6 driving cables 3 which support the beam from carriers 27 running on cross-rails 26 in turn supported on carriers 1 running on beams 2. The conveyer 8 is driven by toothed wheels 7 through reduction gearing 12 and may be in the form of bars carried by parallel chains or a single band having ribs stamped therefrom with rigid scrapers provided on the rear face. The conveyer 8 may be extended along a secondary horizontally and vertically pivotable beam 28 provided with a guiding passage 32 to form an elevator to unload the grain into transport means 35. In one form, Fig. 1 (not shown), the beam 4 supports two conveyers, mounted endto-end and driven in opposite directions to feed the material towards the centre or altematively the sides of the silo. In other forms, the conveyers 8 are screws either mounted on the beams or freely supported in bearings. Anchoring feet may be provided to prevent the conveyers sinking into the grain.
