We have provided a fitting input chute so that the front part of the garbage discharge conveyor can extend through the front opening, so when it is not in use, the conveyor can be retracted into the outer case and the opening can be closed with a shutter to protect the conveyor from rain and dew. It also prevents the general public, especially children, from coming into contact with the garbage storage drum and getting injured.

Then, when the front opening is closed, if the rear door is opened and garbage is thrown in from the garbage inlet, the garbage will be thrown into the drum from the entrance at the rear end of the drum through the chute even while the drum is rotating.

In addition, a movable frame that rotates in the left and right directions around an axis is provided near the front of the lower part of the pedestal that supports the garbage storage drum, and a pair of left and right guide rails provided inside this movable frame are used for the garbage discharge. The outer middle and rear wheels of the left and right frames of the conveyor are mounted so that they can move forward and backward, so that when the conveyor moves forward, the front part of the dust discharge conveyor protrudes from the opening in the open state. When loading garbage into a collection vehicle, even if the rear center of the garbage collection vehicle and the center line of the drum are slightly misaligned, the tip of the conveyor can be collected by adjusting the rotation angle in the left and right direction of the pulled-out garbage discharge conveyor. It can be matched to the car's slot.

Therefore, the operation of the garbage truck becomes easier, and the time from the arrival of the garbage truck to the start of garbage reception is shortened.
