<p>In the present invention, there is disclosed a milling roller module (6) for a surface miner, including a milling roller (7) operating with undershot for loosening the material from the block being mined, a support frame (9) for fastening the milling roller (7) to the surface miner, and a take-up chute (10) for supporting the intermediate conveying of the loosened material in the area of the milling roller (7) and for transferring the material to the downstream discharge belt (11) in a specific manner. The drives (8) are placed into the milling roller (7) and the feed lines are led into the milling roller (7) together with the support frame (9) for fastening the milling roller (7) from the side in the upper third of the milling roller (7) diameter. As a result, it is possible to perform mining operations up to a cutting depth that is equal to half the roller diameter. A take-up chute (10) surrounding a portion of said milling roller (7) at a spaced location from a cutting circle diameter (DS) of said milling roller (7) from a top edge of the level being cut in the direction of rotation of the roller in an angle of about 110 degrees, said take-up chute (10) limiting a conveying space for loosened material to an outside and being provided with a guide tunnel (101) in an area of the intended transfer of the material to said discharge belt (110), said take-up chute being provided downstream of the block being mined in the direction of rotation of said milling roller to guide material and to transfer it to said downstream discharge belt (110) in a specific manner, said take-up chute (10) being connected to the surface miner with one upper joint and two longitudinally adjustable struts (14).</p> |
