A quartz sand transferring device having a cleaning unit is provided to improve the production efficiency by mounting the cleaning means at a predetermined position of a screw conveyer and cleaning accumulated quartz sand without additional cleaning device. A quartz sand transferring device(100) comprises a power transmitting unit(110) transferring driving power; a first pulley(112) rotatively installed at one side of the power transmitting unit; a screw conveyer(120) installed at the lower end of the power transmitting unit and formed with a second pulley(122) interlocked/rotated by the first pulley and a driving belt(124) to send the quartz sand upward from the bottom surface; a rotary shaft(130) installed at the middle of the screw conveyer to be rotatively engaged with the second pulley; at least one cleaning unit(140) installed at a predetermined lower periphery of the screw conveyer; a separation preventing member(150) installed to surround the screw conveyer up and down so as to prevent the quartz sand from being randomly moved away; and supporters(160a,160b,160c) supporting the separation preventing member upward from the bottom surface to be inclined.
