PURPOSE: Apparatus for harvesting underground crop is provided to effectively harvest underground crop by rotating the digging blade upwardly and downwardly, thereby digging out underground crop. CONSTITUTION: Apparatus for harvesting underground crop comprises a main body(110), a circular cutting blade(120), a gear-box(130), an elevating shaft(140), a rotary body, a cam-shaft, a coupling bar(170), a rotary bar(180), and a digging blade(190). The main body is installed in the rear side of farm working machinery. The circular cutting blade can be able to idle by being contacted to furrows in both sides of the main body. The gear box connects to a driving shaft locating the rear side of the gear box. The elevating shaft is perpendicularly rotatable, and is movable upwardly and downwardly, penetrating through the main body and the gear box. The cam-shaft rotatably connects to the power transmission element. A connect-shaft mounted to the coupling bar is installed in top end. The rotary bar rotates around a hinge shaft formed in bottom rear side of the main body up and downwardly. The digging blade is installed in bottom rear side of the rotary bar. |
