The invention discloses a high-efficiency garbage compression device, which comprises a shell, and the bottom of the shell is provided with a lower supporting frame, the lower supporting frame is a T-shaped bracket, and rollers are respectively fixed on both ends of the top of the lower supporting frame, and the lower supporting frame is The two ends of the support frame are respectively provided with rollers, the rollers are set on the rollers, and the drive motor connected to the rollers is arranged on the outer side of the housing corresponding to the rollers; the lower conveyor belt is set between the two rollers, and the An upper supporting frame is arranged above the lower conveyor belt, the upper supporting frame is an inverted T-shaped bracket, and a fixed frame is arranged above the upper supporting frame; vertical guide rails are fixedly arranged at the bottom of the fixed frame. The garbage compression device has a novel structure; the invention ingeniously sets the compression mechanism to compress during the transmission process, and the compression efficiency is high; and the compression time is long, the garbage is hard to rebound after being compressed and shaped, and the solid and liquid are separated after compression; at the same time, sterilization is carried out during the compression process to ensure hygiene .
