The invention discloses a sunlight-accumulating garbage incineration device which is suitable for being applied to a small range of urban areas and achieves processing of intraday garbage cleanly and timely. The sunlight-accumulating garbage incineration device is composed of a squeeze propeller, a feeding helix, a heated body assembly, a focus lamp array, a seat frame, a boiler and a power distribution box, wherein the squeeze propeller, the feeding helix, the heated body assembly, the focus lamp array, the seat frame, the boiler and the power distribution box are connected on a public machine seat. The sunlight-accumulating garbage incineration device is characterized in that a discharge end of the squeeze propeller is connected with the feeding helix, the feeding helix and the front end of a feeding channel are sleeved inside the feeding channel of the heated body assembly coaxially, the feeding helix and the front end of the feeding channel are communicated with and fixedly connected with a discharge port of the squeeze propeller, the other ends of the feeding helix and feeding channel are communicated with and fixedly connected with a feeding port of the a combustion chamber, a left heat exhaust channel, a right heat exhaust channel and an electric heating channel are coaxially arranged on the same wall of the lower portion of the feeding channel of the heated body assembly, wherein the electric heating channel is arranged in the middle. Two channels arranged at the front end of the heated body assembly of the heat exhaust channel are communicated with each other, a channel in the other end of the heat exhaust channel is communicated with and fixedly connected with a combustion chamber of the boiler through a guide pipeline, the other channel of the heat exhaust channel is communicated with and fixedly connected with a chimney of the boiler, the convex lens focus point of the focus lens array is arranged on the external top face of the feeding channel, and the sunlight-accumulating garbage incineration device is simple in structure and low in investment.
