The present invention provides a self-propelled soil selector which is able to provide soil without pause while easily selecting soil used for preventing movement and damage against a pipe and a cable buried under aggregates and soil obtained through excavation when newly establishing or exchanging a pipe and a cable under the ground. The self-propelled soil selector according to the present invention comprises hoppers mounted on the upper part of moving bodies in which caterpillars rolling by the power of an engine and an unmanned control device are mounted in the lower side; a supply conveyor; a cylindrical drum rotating by a drive motor and a chain; a transport conveyor transferring selected soil; a discharge conveyor supplying the selected soil to a conduit line or a cable back filling place; and a discharge guide plate discharging separated aggregates, wherein the cylindrical drum comprises a first circular support frame and a second circular support frame, which are placed on both sides so that the cylindrical drum is placed on a rotary supporting roller to be rotated, multiple bars welded within the inner diameter of the first and second support frames at constant intervals so that the intervals become discharge holes, a support ring welded to the periphery of the multiple bars to prevent bending, a spiral collar welded within the multiple bars, and a chain gear formed on the outer periphery of the first support frame and connected to the chain connected to the drive motor. The self-propelled soil selector further comprises a detaching member which is formed on the exterior of the multiple bars, mounted on the moving body and rotated in gear with the multiple bars to separate the soil blocked between bars. |
