The invention discloses a garbage jettison device for high-rise residential buildings, and belongs to the field of high-rise building garbage jettison devices. The garbage jettison device for the high-rise residential buildings comprises an
elevator shaft and a controller, the
elevator shaft is arranged on a wall, and an
elevator is arranged in the elevator shaft. The device can achieve the purpose that the high-pressure gas in a high-pressure gas tank enters a shock-absorbing inflating
airbag through an air inlet
pipe, shock-absorbing inflating
airbag effectively absorbs the vibration, and reduces the
noise, the shock-absorbing inflating
airbag pushes the lower end of a first speed-reducing plate, the inclination angle increases, the speed
control effect is effectively achieved, the elevator is moved up and down in the elevator shaft, a
mixed gas transportation pipeline is inflated by an inflating cylinder through an air outlet
pipe, thereby achieving the inflation of the high-pressure gas tank, the shock-absorbing inflating airbag can effectively work, the labor intensity is effectively reduced, the speed of a heavy object falling through a garbage passage is prevented from beingtoo fast, the
noise is effectively reduced, a lighter material falling is prevented from being too slow, and the jettison efficiency is ensured.
