<p>Apparatus (10) and method for loading material, particularly for use in underground mines. The apparatus (10) has a body supported on wheels (25) or crawler tracks, which permits movement of the body on a surface, and a conveyor assembly mounted on the body to transport material from a front portion of the conveyor assembly (27) to a rear portion thereof. Advancing structure (82, 84, 85) cooperates with the conveyor assembly to cause essentially axial movement of the conveyor assembly (27) as a reaction to force from the advancing structure (82, 84, 85). Penetrating structure (50) mounted adjacent the front portion of the conveyor (27) is adapted to be forced into material to be loaded and is rotationally oscillated about a horizontal transverse axis disposed normally to the longitudinal axis to facilitate penetration of the material. Use of advancing (82, 84, 85) structure to force the penetrating structure (50) into the material eliminates necessity for tractive forces applied to the wheels or tracks of conventional machines, thus overcoming scuffing or wear problems associated with such wheels or track. The body itself either carries the fixed conveyor assembly and is moved by the advancing structure as a total assembly, or alternatively the body is fixed by anchoring structure and the advancing structure moves the conveyor assembly relative to the body. The front portion of the conveyor can be raised to enter the material at a higher elevation.</p> |
