This utility model relates to the field of ore conveying technology and provides a mining ore conveying device, including: two conveyor belts and a cleaning box, wherein the cleaning box is disposed between the two conveyor belts. This utility model utilizes a method where a round rod rotates from bottom to top, applying an upward force to a movable frame, causing the movable frame to move upward. Simultaneously, this causes a sliding strip to move upward along the inside of a chute, and simultaneously causes a pushing frame to move upward, inserting it into the gap between two adjacent conveyor rollers and applying an upward thrust to the ore. Then, the round rod rotates from top to bottom, applying a downward force to the movable frame, causing the movable frame, sliding strip, and pushing frame to move downward. This process is repeated. In this way, when the conveyor rollers convey ore, it can prevent ore from getting stuck between the two conveyor rollers, avoiding ore accumulation and thus preventing damage to the conveying equipment, thereby increasing the service life of the conveying equipment.
