The present invention relates to an organic waste transport device that can prevent and ensure safe and sanitary operation.

  Organic waste such as garbage (hereinafter referred to as “garbage etc.” if necessary) generated from kitchens at home, hotels, restaurants, etc., is discharged in plastic bags and other plastic bags. It often has a characteristic of high perishability, and some are already corrupt.

  The above-mentioned method is most generally employed in which the above garbage is transported to a garbage disposal facility by a garbage truck, put into a garbage pit, and then put into a predetermined garbage hopper by a crane bucket.

  However, garbage that cannot be grasped by the crane bucket remains in the pit. Therefore, in the case of raw garbage, the remaining raw garbage is rotted, and there is a concern about generation of bad odor, soot and fly, and generation of dangerous gas.

  It is also possible to feed garbage into a hopper equipped with a cutting device, pass the tube conveyor from the cutting device and coarse pulverizer, and send the garbage to the wet crushing and sorting device. Alternatively, there is a problem that the leftovers stick to the chain like a bowl and eventually cannot be conveyed, and there is another problem that the leftovers rot.

Furthermore, it is possible to feed garbage into a hopper equipped with a cutting device and send it to the wet crushing and sorting device through the flight conveyor from the cutting device and coarse pulverizer, but a plastic bag is entangled in the chain in the trough. There is a problem that the leftovers are stuck to the chain like a bowl and cannot be transported or moisture cannot be sent.
