What are the four stages of the working process of the filling and compression mechanism of the rear-loading compression garbage truck?

Rear loading garbage truck generally requires four stages to fill the compression mechanism.

In the first stage, the swing plate swings up, ready to be inserted into the loose trash.

In the second stage, the guide plate drives the swing plate to move down and inserts the loose garbage in the collection box.

In the third stage, the swing plate swings downward in a circular arc, scraping the garbage to make it begin to enter the main compartment.

In the fourth stage, the guide plate drives the swinging plate to move upward, and fills the garbage into the main compartment, thus completing a filling cycle.
