Abstract: A vibrating conveyor having a circular or helical conveying conduit driven with a vibrating motion by way of an electromagnet having alternating voltage. The conveying conduit emerges, at its end, into an overflow chute constructed in the form of a channel switching system. An overflow channel oscillates with a reciprocating motion about a pivoting shaft. Mechanical and electrical control devices are provided, so that the overflow channel can be brought into variable oscillating positions. The overflow channel includes a U-shaped section, pressing radially on a sliding surface, forming a circular zone and fixed on a pivoting shaft mounted on the sliding surface. This section is driven by a reciprocating motion in the peripheral direction of the circular zone about the pivoting shaft. Through the pivoting shaft, this section is rigidly connected to a guide rail open downwardly, arranged beneath the sliding surface and extending parallel thereto.
