The utility model discloses an artificial simulated rainfall experiment device which comprises a sprinkler (1) and a water supply device. The water supply device comprises a water tank (2) and a Marriott tube (3) connected with the water tank. A water outlet pipe (4) is arranged on the water tank and is connected with a water supply pipe (7) on the sprinkler through a valve (5) and a hose (6). By using the Marriott principle, the level of water in a water collection pipe in the sprinkler can be conveniently adjusted, the sprinkler can obtain a fixed water level, the rainfall with constant intensity is obtained, the structure is simple, the transportation and the operation are convenient and the production cost is low. The sprinkler of the utility model is a needle tube type sprinkler. By adjusting the level of water in the water collection pipe in the sprinkler or the density of needles and the aperture of the needles, the rainfall intensity can be adjusted. By adopting the device, different rainfall intensit
