A movable power screen device is provided to secure a stable driving of a vibrator by quickly relieving or eliminating drop impact of the aggregates by installing plural springs between a support structure body and a screen structure body. The movable power screen device(1) is composed of a trailer(10) equipped with a transfer conveyor(11); a support structure body(20) installed at the upper part of the conveyor formed at the trailer, wherein the upper part of the support structure body is inclined to one side; a screen structure body(30) having at least one vibrator installed at a body to self-vibrate and a screen(31) inclined to one side at the upper part of the inclined support structure body, dropping the aggregates passing through the screen to the conveyor by self-weight, transferring the aggregates that do not pass through the screen, along an inclined plane and discharging the aggregates through a discharge port(34) formed at one side; and plural springs(41,42) arranged between the support structure body and the screen structure body placed at the support structure body to elastically support the screen structure body. |
