ABSTRACT:
Apparatus for feeding bulk material, such as, for example, chips, shavings, or the like, into a spiral pump or press, comprises a supply funnel, a feed line, and a rotatably driven conveying and compacting means. The latter comprises a vertically oriented axial shaft which comprises a helicoid portion within the vicinity of the supply funnel, and a helical thread portion within the vicinity of the feed line. The helicoid portion is spaced from the inner peripheral surface of the supply funnel by means of a predetermined spacing, and the inner peripheral surface of the supply funnel is provided with a plurality of pins equiangularly disposed about the inner periphery or circumferential extent of the supply funnel. The pins are arranged within a horizontal plane, and may be disposed within multiple horizontal planes. The pins may also have different lengths depending upon the particular bulk material being fed, conveyed, and compacted, and the helicoid portion of the axial shaft is provided with recesses defined within peripheral portions thereof for accommodating the pins of the supply funnel so as to permit the axial shaft, and the helicoid portion thereof, to rotate so as to feed, convey, and compact the bulk material.
