PURPOSE: A tree root digging equipment is provided to separate the soil nearby the root of a tree and the soil outside of the root area by digging the soil in the original place without moving around the tree. CONSTITUTION: A tree root digging equipment comprises the following steps. A rotary drum(100) is installed surrounding a tree with a fixed interval from the ground. A rotary guide(120) is installed in a ring shape along the outer periphery of the rotary drum, and rotates with the rotary drum. A fixing guide(200) is installed in a ring shape on the outer side of the rotary guide, supports the rotary guide to enable the rotation of the rotary guide, and combined with the rotary guide. A rotation apparatus(400) rotates the rotary drum. An excavation blade(160) digs into the ground by rotating with the rotary drum at the same time. The end part of a pneumatic cylinder(300) is rotatably combined with a digging wing, and rotates the digging wing. The digging wing is turned with a tilt in the inside starting from one end of the digging wing by pneumatic cylinders. A chain(410) is fixed along the outer circumference surface of the upper end of the rotary drum. A sprocket wheel(420) rotates the rotary drum by rotating in the state in which the chain is caught on the sprocket wheel. A rotation driving source(430) rotates the sprocket wheel. The first pressure hose(310) is connected to the pneumatic cylinder. The second pressure hose(330) is connected to an air compressor. A passage(320) enables the compressed air to pass between the first pressure hose and the second pressure hose.제자리에서 회전하며 흙을 파내는 것이 가능하므로 작업공간을 적게 차지하도록, 원통 형상으로 이루어지고 수목 주위를 에워싸는 상태로 지면과 일정 간격을 두고 회전가능한 상태로 세워져 설치되는 회전드럼과, 회전드럼의 외면 둘레를 따라 링 형상으로 형성하여 설치되고 상기 회전드럼과 함께 회전운동하는 회전가이드와, 회전가이드의 바깥쪽에 링 형상으로 형성하여 설치되고 상기 회전가이드를 회전가능하게 지지하며 회전가이드와 결합되는 고정가이드와, 회전드럼을 회전시키기 위한 회전장치와, 회전드럼과 지면 사이에 설치되고 한쪽 끝 부분이 회전드럼의 하부 끝부분 둘레를 따라 일정한 간격을 두고 회전가능하게 결합되며 회전드럼의 회전시 함께 회전운동하면서 땅속으로 파고드는 굴착날과, 한쪽 끝 부분이 회전드럼에 회전가능하게 결
