Description

Technical Field

[0001] The utility model belongs to the technical field of special sanitation vehicles, and in particular relates to a box body sewage discharge device for a sanitation vehicle. Background Art

[0002] With the acceleration of urbanization and the improvement of people's living standards, the garbage and waste generated in the process of urban production and life has increased significantly. The collection and transportation of garbage is the most urgent problem to be solved. Compression garbage trucks crush, compress and compact the garbage. The loading capacity is larger than that of ordinary garbage trucks, which reduces the number of garbage truck transportation. Loading and unloading garbage does not pollute the environment and reduces the labor intensity of cleaners.

[0003] The compression garbage truck includes a sealed compartment, a push plate, a hydraulic transmission system and an electrical control system. The process of garbage compression and filling is as follows: when the filling hopper is full of garbage, the scraper opens and is ready to insert loose garbage. The slide plate drives the scraper to move downward together and insert into the garbage for crushing and initial compression; then, the scraper rotates forward to further compact the garbage. After the scraper is in place, it moves upward with the slide plate to compact the garbage into the garbage bin and return to the starting position. During the continuous compression and filling of garbage, the push shovel overcomes the back pressure under the action of the extrusion force and gradually retreats, so that the garbage fills the entire garbage bin evenly. After the garbage bin is filled with garbage, it is completely closed and will not pollute the environment during transportation.

[0004] When unloading garbage at the treatment (or landfill) site, the compression garbage truck first lifts the filler, opens the rear end of the garbage bin, and moves the push shovel originally parked at the front end of the garbage bin backwards to push the garbage out of the garbage bin horizontally. Although the garbage truck body is sealed, when the push plate compresses the garbage, due to the pressure, a small amount of garbage residue will pass through the gap between the push plate and the surrounding of the body and be squeezed to the back of the push plate. When discharging sewage, solid-liquid separation cannot be achieved, and it also makes it difficult to clean the compartment.

[0005] In view of the above-mentioned prior art, the applicant has made a useful design and proposed a box sewage discharge device for a compression type garbage truck. The technical solution to be introduced below is produced in this context. Utility Model Content
