Abstract: An enclosed type two-stage garbage compaction and storage structure, in particular a structure having both a hydraulic cylinder and a rotary inner cylinder provided with guide plates to compact garbage in two stages. The structure includes a housing, the hydraulic cylinder, and the inner cylinder. The housing is provided with a plurality of garbage slots to achieve quick collection of garbage. The housing has a front outlet and a lid. A slide plate is provided in front of the front outlet. The hydraulic cylinder is disposed horizontally, and has a piston rod at a front end and a push stop plate connected to the piston rod for pushing dumped-in garbage into the inner cylinder. The inner cylinder has a gate at an entrance thereof and a plurality of guide plates on its inner wall. When the inner cylinder rotates, a compaction effect is generated.

Abstract: A multi-slot closed type powerful garbage compression structure including a housing, an inner cylinder internally provided with guide plates and being inclined forwardly, and a push bar behind the inner cylinder. The housing is provided with four slots at a rear section adapted to receive garbage, and a garbage outlet at a front end, the outlet being provided with a slide plate, and a waste water receiving trough at a bottom side. When garbage is dumped into the housing via the slots, the push bar rotates to push the garbage into the inner cylinder which rotates to compress the garbage. When the garbage inside the inner cylinder is full, the push bar may prevent reverse flow of the garbage. By the use of both the push bar and the guide plates inside the inner cylinder, better compression effects are achievable to reduce garbage storage space and eliminate use of hydraulic cylinders and thrust devices.
