TECHNICAL FIELD

[0001] The utility model relates to the technical field of compression garbage truck, concretely is a top cover mechanism device of compression garbage truck. BACKGROUND

[0002] The compression garbage truck drives the filler and the scraper to compress the garbage through the hydraulic system, and the volume of the compressed garbage is reduced, facilitating transportation. In the transportation process, the sewage compartment collects the sewage generated in the compression process to prevent environmental pollution. After the garbage truck reaches the treatment point, dumping and unloading can be carried out through the operation system. The current dumping position of some models is above the top cover, which needs to be opened when dumping garbage.

[0003] Patent CN217147247U proposes a novel top cover mechanism device of compression garbage truck. When unloading, the filler rotates counterclockwise around the hinge position between the filler and the box body. At this time, the filler can push the right end of the front cover upwards. At this time, the front cover rotates counterclockwise around the hinge center.

[0004] The above-mentioned scheme is basically the same as the opening effect of the existing garbage truck top cover, but the structure has the defect that when dumping garbage, the garbage is easy to fall out from both sides, lacking a certain protection function to prevent garbage from falling.
