The lower extreme of fender cover 421 connects the both sides outside limit of seventh conveyer belt 43, shelters from seventh conveyer belt 43, can effectively prevent heavy type rubbish in transit from jumping out and dropping subaerially, also can effectively reduce in the air that the partial soil ash that carries in the heavy type rubbish escapes, guarantees the clean and tidy degree in sand and soil separation unit 4 region and wind power separation region.

The light garbage such as plastic bags, leaves and the like blown into the air duct 512 by the first fan 514 and the second fan 515 is driven by the air to move into the exhaust bin 513.

The upper end face and the side face of the air exhaust bin 513 are provided with openings, the openings are connected with air outlet pipes 54, and air is guided to be exhausted from the air outlet pipes 54. A mesh enclosure 55 is arranged in the exhaust bin 513. Mesh openings are provided on the top surface and each side surface of the mesh enclosure 55. When wind enters the wind outlet pipe 54 through the wind discharging bin 513, the mesh enclosure 55 can intercept light garbage such as plastic bags and leaves.

A ninth conveyor belt 53 is provided below the exhaust bin 513, and light garbage such as plastic bags fed into the exhaust bin 513 from the air duct 512 falls on the ninth conveyor belt 53 and is conveyed to a garbage collection area or a treatment area via the ninth conveyor belt 53 for treatment.

Referring to fig. 17, a mesh plate 56 is further disposed at the bottom of the mesh enclosure 55, and the mesh plate 56 is also provided with meshes, so that light garbage such as plastic bags and leaves can be intercepted at least twice, the intercepting effect is good, and the possibility that the light garbage enters the air outlet pipe 54 and is discharged from the air outlet pipe 54 is further reduced.

A cleaning assembly 57 is disposed within the mesh enclosure 55. The clearing assembly 57 comprises a flexible cord 571 and a weight 572. The flexible rope 571 is fixed on the top surface of the mesh enclosure 55, the flexible rope 571 falls into the mesh enclosure 55, the heavy drooping object 572 is fixed at the bottom of the flexible rope 571, when wind enters the air outlet pipe 54 from the air exhaust bin 513, the wind can blow the heavy drooping object 572 to enable the heavy drooping object 572 to swing and impact the side surface of the mesh enclosure 55, the mesh enclosure 55 and the mesh plate 56 can vibrate, so that light garbage such as plastic bags, leaves and the like attached to the side surface, the top surface or the mesh plate 56 of the mesh enclosure 55 can fall off, the effect of automatically cleaning the mesh enclosure 55 is achieved, the wind power action of the first fan 514 and the second fan 515 is adopted in the cleaning process, manual operation is not needed again, and labor is saved.

The flexible rope 571 can be bound on the top surface of the mesh enclosure 55 by a cloth strip or a plastic rope; the weight 572 may be provided as a block or a ball made of plastic or metal. And the cleaning assembly 57 is provided with a plurality of cleaning assemblies 57, each cleaning assembly 57 is uniformly distributed on the top surface of the mesh enclosure 55, and each heavy pendant 572 not only can impact the mesh enclosure 55 in the swinging process, but also can impact each other, so that the impact strength of the heavy pendant 572 on the mesh enclosure 55 is increased, and the vibration effect of the mesh enclosure 55 is enhanced.
