The invention relates to a potato integrated treatment device which comprises a harvester, a cleaner and a deep treatment apparatus. One integral device integrates the harvesting and cleaning, thereby achieving the effect of quick and efficient agricultural product deep processing. By arranging and improving all the components of the apparatuses, the integrated device has the advantages of higher integral efficiency and higher durability. By improving the material of the slide plough, the wearing parts can keep high strength and high hardness, and thus, can not become the weakness of the integral device, so that the integral durability of the device is improved.
