Vibrating conveyor

A vibrating conveyor apparatus for conveying an object, said vibrating apparatus comprising:

• a trough;
• a frame supporting said trough by a supporting structure;
• and
• a vibrator connected to said trough so that said trough vibrates forwardly and backwardly, said supporting structure comprising;
• a lever assembly having a base lever and a vibration lever, said base layer and said vibration lever the respectively rotatably connected together at lower ends thereof by a common connecting shaft, said base lever being rotatably supported at an upper end thereof through a first shaft by said frame, said vibration lever being rotatably connected to an upper end thereof through a second shaft with said trough, said base lever having a block at each side edge thereof, a spring being attached between each of the blocks of said base lever and each of side edges of said vibration lever, said vibration lever being held by said base lever through said spring so as to be switchable around said common connecting shaft, a direction in which the object on said trough is conveyed being reversed by rotating said lever assembly partly around said first shaft of said base layer so as to change an angle of inclination of said lever assembly with respect to a lengthwise direction of said trough between a first angle at which the object moves on said trough in one direction and a second angle at which the object moves on said trough and an opposite direction.
