[0022] In the present utility model, the push rod 116 extends upward, which will drive the bucket flap 113 to rotate on the second connecting frame 112 and the first sleeve rod 111 through the second sleeve rod 115 and the connection block 114, so as to present an open state. When the push rod 116 contracts, it will drive a plurality of bucket flaps 113 to present a closed state, thereby realizing the opening and closing of the bucket flaps 113 for grasping garbage. After the cleaning is completed, the pump 312 is started, which will extract the lubricating oil inside the oil tank 310 and spray it onto the connection between the pin and the sleeve through the oil outlet pipe 313, thereby reducing the wear between the pin and the sleeve and prolonging the service life of the components.

[0023] Working principle: the electric push rod 116 extends upward, and it will drive the bucket 113 to rotate on the second connecting frame 112 and the first set of rods 111 through the second set of rods 115 and the connecting block 114, so that it is in an open state, and when the electric push rod 116 contracts, it will drive multiple sets of bucket petals 113 to be in a closed state, so as to realize the opening and closing of the bucket petals 113 for grabbing garbage. When the electric push rod 116 drives the grab bucket to move, the airbag 210 is in a compressed state, and the spring inside the airbag 210 will gradually drive the airbag 210 to reset. When the electric push rod 116 extends upward, the grab bucket opens. When the electric push rod 116 is retracted, the multiple sets of bucket petals 113 are reset, which can fix the garbage. After the push rod 116 is reset, it will squeeze the airbag 210, and the gas inside it will be squeezed out, and then pass through the connecting pipe 211, the flat tube 212 and the connecting plate 213, and finally enter the outlet pipe 214 to be blown out.
