The invention discloses a guide screw structure vacuum sewage discharge device used in a railway sealed toilet. The guide screw structure vacuum sewage discharge device is characterized in that a hose coiling mechanism, a hose guide device, a speed reducer and an automatic control device are installed in a housing, a driving gear driven by the speed reducer drives a first driven gear and a second driven gear through a chain, the first driven gear drives a shaft on which the hose coiling mechanism is arranged, and the second driven gear drives a guide screw; the hose guide device is installed on a nut sleeving on the guide screw; one end of a sewage discharge hose is connected with a quick connector, and the other end of the sewage discharge hose penetrates through the hose guide device to be connected with a sewage discharge pipe positioned at the inner barrel of a coiling disc of the hose coiling mechanism; a hose collection limit switch and a hose release limit switch are installed at two ends of the guide screw; the hose collection limit switch and the hose release limit switch are connected with the automatic control device. By applying the guide screw structure vacuum sewage discharge device, automatic collection, release and guiding of a hose can be realized, the work efficiency is greatly improved, and the product structure and operation process are optimized.
