The principle of the garbage truck is that when the filling bucket of the sanitation garbage truck is full of garbage, the scraper opens, and the skateboard drives the scraper to move downward together, penetrates into the garbage for breaking and initial compression, and the scraper reverses forward to further compact the garbage. After the scraper is in place, it moves upward with the skateboard to compact the garbage and fill it into the garbage bin, and then returns to the starting position. The entire task process is automatically controlled. When the garbage is continuously compressed and filled, the push shovel gradually retreats under the effect of the squeezing force, suppressing the back pressure, and completing the two-way compression of the garbage and filling the entire garbage bin evenly. When the Sanitační kamion na popelnici vykládá odpadky na místě ošetření (nebo skládky), výplně je zvednuta, push lopata se pohybuje dozadu a odpadky v koši na odpadky je vytlačeno v horizontálním směru .
