PURPOSE:To drive a vibrating trough at a correct period, by switching a driving gear at each half turn of rotation to drive the vibrating trough in two-way operation of high and low speeds. CONSTITUTION:A horizontally placed conveyer vibrating trough is driven by an interlocking member 34 through a supporter 39 at an end part of said member 34. A driving gear is arranged on a base B, and a rotary member 24 at the side of a driving shaft 13 is connected to high and low speed driving mechanisms H, L for a motor 7 an speed reduction gear 9. A disc 28 is provided to an end part of the shaft 13, and two each of detectors 30, 31, 30', 31' are provided to both sides of said disc 28, then conveyance can be correctly performed by switching clutches 14, 19 to high and low speed at each half turn of rotation of the disc. |
