Object collector

An object collector for collecting objects in a plurality of containers, comprising

• a tank body having a top inlet opening, a front side wall, a back side wall, a right side wall, a left side wall, and a door installed to one of said side walls;
• an inlet device, which comprises a swinging plate made of light material and a mounting device for pivotally mounting said swinging plate horizontally above said top inlet opening at an upper portion of said tank body, so that once a downward pushing force is applied to said swinging plate, said swinging plate is swung downwardly to open said inlet opening of said tank body, in which said swinging plate is composed of an entrance portion and a weight portion, said mounting device including two pivot pins protruding on a right and a left side of said swinging plate respectively and at an intersection position of said entrance portion and said weight portion, so that said swinging plate is installed to the top portion of said tank body by rotatably connecting said two pivot pins with two receiving sockets provided at two corresponding positions on said two opposing side walls respectively, so as to enable said swinging plate rotating about an axis between said two pivot pins, wherein said entrance portion has a length and a width at least equal to a length and a width of the containers, and an average thickness thinner than said weight portion, so that the weight of said entrance portion is equal to the weight of said weight portion;
• a guiding device, which comprises at least two guide rails installed within said tank body without obstructing the swinging path of said swinging plate, wherein said two guide rails are downwardly extended from an upper portion of one side of said tank body toward a lower portion of the opposing side of said tank body below said swinging plate, and that the distance between said two guide rails is narrower than the width of the containers, two upper ends of said two guide rails being mounted beyond and adjacent to a down swinging edge of said swinging plate and two lower ends of said two guide rails being extended and mounted under another opposing edge of said swinging plate with a predetermined vertical distance;
• whereby, the container and the objects thereon, which are sliding down from said swinging plate due to gravity, may fall down to said guiding device gradually while said swinging plate is swinging down due to the weight of the container and the objects, in which said two guide rails of said guiding device guide the falling of the container to slide toward the lower ends thereof, and that when the container and the objects thereon leave said swinging plate, said swinging plate may swing up back to a normal horizontal position thereof and push the failing container to toss over, so that the objects within the container throw down by means of the gravity;
• a receiving device, which is positioned under said guiding device in said tank body for receiving all the objects fallen down from the container;
• and
• a collecting device, which is placed in a predetermined position adjacent to the lower ends of said two guide rails for receiving and collecting the containers fallen from said guiding device.
