Abstract: The present invention relates to an object collector for collecting objects in a plurality of containers, which comprises a tank body, an inlet device, a guiding device, a receiving device, and a collecting device. The tank body has a top inlet opening. The inlet device comprises a swinging plate which is pivotally and rotatably mounted, above the top inlet opening, to the upper portion of the tank body by means of a mounting device. The container and the objects thereon, which are placed on the swinging plate, may fall down from the swung down swinging plate due to the weight of the container and the objects. The guiding device comprises at least two guide rails which are mounted and extended from one side of the upper portion of the tank body toward the opposing side of the lower portion of the tank body for guiding the falling down container to slide down and toss over.
