providing lifting power for the lifting lugs (2), and lifting the bucket (11) in a containing state to a certain height away from the ground; removing the continuous closing force, enabling the sliding rod (4) to slide downwards in the sleeve (5), enabling the sealing door (12) and the pressing plate (9) to move downwards along with the sliding rod (4), enabling the sealing door (12) to be opened continuously, and enabling the sealing door (12) to slide on the pressing plate (9) until the door edge of the sealing door (12) is separated from the pressing plate (9);
the muck in the bucket (11) is continuously discharged along with the continuous opening of the sealing door (12), and after the muck is basically discharged, the sealing door (12) is automatically and completely closed under the certain force provided by the elastic hinge connection.
