The invention belongs to the technical field of garbage sorting, and in particular relates to a small-capacity intelligent garbage sorting device, aiming to solve the problem of insufficient usability of automatic garbage sorting devices in the prior art. The invention provides a small-capacity intelligent garbage sorting device, which includes a garbage sorting device body and a controller. The garbage sorting device body is provided with a garbage input port, a garbage transporting mobile box, and a plurality of sorting garbage containers; the surrounding side of the garbage transporting mobile box A garbage detection mechanism is provided, and the controller controls the garbage transport moving box to put the garbage into the designated sorting garbage container based on the detection result of the garbage detection mechanism. The intelligent garbage sorting device of the present invention can realize multiple functions such as garbage input detection, garbage category identification, non-rigid garbage compression, automatic garbage delivery, garbage filling state detection, solid-liquid separation, etc., and ensures safe operation of the device from the perspective of hardware design and workflow , to prevent mis-throwing of garbage, high space utilization rate, and has broad application prospects.
