## CPC

- B65G 27/32: with means for controlling direction, frequency or amplitude of vibration or shaking movement
- B65G: TRANSPORT OR STORAGE DEVICES, e.g. CONVEYORS FOR LOADING OR TIPPING, SHOP CONVEYOR SYSTEMS OR PNEUMATIC TUBE CONVEYORS (packaging B65B; handling thin or filamentary materials, e.g. paper sheets or thread, B65H; cranes B66C; portable mobile or lifting or hauling appliances, e.g. hoists, B66D; devices for lifting or lowering goods for loading or unloading purposes, e.g. fork-lift trucks, B66F9/00; emptying bottles, jars, casks, barrels or similar containers, not otherwise provided for, B67C9/00; delivering or transferring liquids B67D; filling or discharging vessels for liquefied, solidified or compressed gases F17C; pipe-line systems for fluids F17D)

## Abstract

A supporting means of a trough has a lever assembly with a base lever and a vibration lever respectively rotatably connected together at lower ends thereof by a common connecting shaft. The base lever is rotatably supported through a first shaft by a frame. The vibration lever is rotatably connected through a second shaft with the trough. The vibration lever is swingably held through spring means by the base lever. The direction in which the object on the trough is conveyed is reversed by rotating the lever assembly partly around the first shaft of the base lever so as to change the angle of inclination of the lever assembly with regard to the lengthwise direction of the trough between a first angle “A” at which the object on the trough moves in a certain direction and a second angle “B” at which the object moves in an opposite direction.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The vibrating conveyor apparatus of claim 1, wherein a distance between a centerline of said first shaft and a center line of said second shaft is less than 20 millimeters.

### Claim 3 (depends on 1)

The vibrating conveyor apparatus of claim 1, wherein a center line of said first shaft and a center line of said second shaft are substantially collinear.
