PURPOSE:To reduce the height of a whole conveyor, by a method wherein, in a vibrating conveyor for bulky material, two rotary shafts, whereto two each unbalancing weights are secured respectively, are located within a common surface paralleling a direction in which the counterweights extend. CONSTITUTION:Through running of a motor 16, a rotary shaft 12 through a belt 20 and a rotary shaft 13 through gears 21 and 22 are turned in a reverse direction to each other and at the same speed, and directions F of their respective centrifugal forces of unbalancing weights 23, 24 and 25, 26 are alternately brought to a reverse and a forward direction. In this case, a moment Fl is produced in the case of a distance (l) between the rotary shafts 12 and 13, and is exerted on a counterweight 3 and a trough 1. The moment of inertia, however, is sufficiently large and is prevented from exercising an influence on vibration, and the two rotary shafts 12 and 13 are located within a surface in a direction in which the weight 3 extends. This causes the trough to provide a linear vibration, which results in being capable of reducing the height of a whole conveyor to the minimum. |
