Crushing device for classified recycling of household garbage resources

The crushing device for classified recycling of the household garbage resources comprises a crushing tank, a fixing frame is fixedly installed on the surface of the middle end of the top of the crushing tank, and a rotating motor is fixedly installed on the surface of the top of the inner side of the fixing frame. When the whole device is driven by a single rotating motor, a transmission rod and a rotating rod can be driven to rotate synchronously, so that after a crushing roller rotates to crush garbage, garbage scraps which do not pass through a screening plate can roll into a lifting frame under the action of gravity, and the crushing efficiency is improved. And when the auger blades rotate along with rotation of the rotating rod, garbage rolling into the lifting frame can be rotationally lifted and moved into the left side of the crushing tank again, garbage crushing treatment is conducted again, the energy consumption of the whole device is reduced, meanwhile, the crushing efficiency and quality are impr
