The invention belongs to the technical field of kitchen equipment, and particularly relates to an automatic pouring device for a vegetable washing sink filter cylinder. A handle is held to pull downwards, a steel rope hanging hole I downwards pulls a filter cylinder steel wire rope, a steel wire rope drum drives a filter cylinder turnover shaft to rotate, the filter cylinder turnover shaft drivesa whole filter cylinder assembly to turn over upwards, the filter cylinder upwards turns over about 180 degrees along with the filter cylinder assembly, and an opening of the filter cylinder downwardsdirectly faces a filter residue falling hole, so that inside garbage is poured out; meanwhile, a steel rope hanging hole II downwards pulls a cover plate steel wire rope, the cover plate steel wire rope inclinedly downwards pulls a steel rope suspension loop, and a cover plate is deviated from the lower surface of a table top and then downwards turns over about 80 degrees around a cover plate hinged shaft, so that a passageway is opened for the garbage, and the garbage in the filter cylinder falls into a dustbin through the filter residue falling hole. The automatic pouring device for the vegetable washing sink filter cylinder provided by the invention has the beneficial effects that when the garbage in the filter cylinder is poured, a user has no need to contact the dirty filter cylinderby hand and has no need to use soap to wash hand gotten dirty by the filter cylinder during a vegetable/dish washing process, and only the handle needs to be kept clean, so that the time is saved, and the device is simple to operate.
