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.

Abstract: A driving unit includes an electromagnet (33), a vibration plate (11) arranged on one side of the electromagnet (33), and a complementary vibration plate (32) arranged at the opposite side of the electromagnet (33). The parts (1, 2) of the vibration conveyor that need to vibrate are firmly secured to the vibration plate (11). The electromagnet is secured to the complementary vibration plate (32) in a vertically adjustable manner. The vibration plate (11) and the complementary vibration plate (32) are elastically connected to each other. The elastic connection is ensured by at least three supporting beams (29) that are uniformly distributed around the circumference of the winding of the electromagnet (33) at an oblique angle with the winding axis of the electromagnet (33). The supporting beams (29) are connected to the vibration plate (11) and to the complementary vibration plate (32) by leaf spring sets (30, 31).
