Two first weight sensors 13 are fixed to the bottom of the garbage hoist trolley 11 and can measure the weight of the trolley 11 and the garbage hoist grab 14 and the grabber.

The garbage hopper 2 is positioned below the right end of the crane girder 12, and the middle part of the garbage hopper 2 is clamped on the garbage hopper support 21 through the self gravity; the garbage hopper 2 can accommodate the feeding amount of the garbage crane grab bucket 14 once, the width of the garbage hopper 2 is larger than the maximum opening width of the garbage crane grab bucket 14, the phenomenon that the grab bucket collides with the hopper wall and garbage is scattered on a platform is avoided, and the garbage hopper support 21 plays a role in supporting the garbage hopper 2. The garbage hopper 2 is also fixedly provided with a second weight sensor 22, a garbage hopper gate 23 and a garbage hopper gate oil cylinder 24; four or more second weight sensors 22 are uniformly arranged on the garbage hopper support 21; the weight in the waste hopper 2 can be measured. The right side of the garbage hopper 2 is provided with a garbage hopper gate 23 which can move up and down, the garbage hopper gate 23 is connected with a garbage hopper gate oil cylinder 24 through a shaft, and the garbage hopper gate oil cylinder 24 provides driving force for the up and down movement of the garbage hopper gate 23.

Garbage feeder 3 is located the below of garbage hopper 2, and with the fixed sealing connection of the discharge gate of garbage hopper 2, the discharge gate of garbage hopper 2 has the angle, and the slope setting is avoided falling the striking to garbage feeder 3 from garbage hopper 2 straight line.
