The invention relates to the technical field of milling and excavating machines, in particular to mining and excavating equipment which comprises a supporting arm I. Fixed crushing rollers for crushing ores are rotationally arranged on the two sides of the front end of the supporting arm I. The contour of the side wall of each fixed crushing roller is higher than the front end of the supporting arm I. Multiple sets of crushing cones are evenly fixed to the side wall of each fixed crushing roller in the circumferential direction. And an extended crushing mechanism capable of being connected with the fixed crushing roller is installed on the supporting arm I, the extended crushing mechanism is unfolded to be used for increasing the transverse crushing distance of the excavating equipment, and the extended crushing mechanism is folded to be used for reducing the transverse length of the excavating equipment, and the milling and excavating machine has the beneficial effect that the milling and excavating machine is provided with the fixed crushing roller and the extended crushing roller. After the extended crushing roller is unfolded and connected with the fixed crushing roller, the transverse milling and digging distance can be increased, and the device is suitable for milling and digging of a low-hardness rock stratum; after the extended crushing rollers are folded, the extended crushing rollers can be drawn close to the two sides of the milling excavator so as to be prevented from colliding with rock walls.
本发明涉及铣挖机技术领域，更具体的说是一种采矿挖掘设备，包括支撑臂Ⅰ，支撑臂Ⅰ前端的两侧均转动有用于破碎矿石的固定粉碎辊，固定粉碎辊的侧壁轮廓高于支撑臂Ⅰ的前端，固定粉碎辊的侧壁上周向均匀固定有多组破碎锥，支撑臂Ⅰ上安装有可与固定粉碎辊连接的延长粉碎机构，延长粉碎机构展开用于增长挖掘设备的横向破碎距离，延长粉碎机构收起用于减小挖掘设备的横向长度，其有益效果是提供一种具有固定粉碎辊和延长粉碎辊的铣挖机。其中当延长粉碎辊在展开并与固定粉碎辊连接后，可实现增加横向铣挖距离，适用于低硬度岩层的铣挖；当延长粉碎辊在收起后，可靠拢在铣挖机两侧，以避免与岩壁发生碰撞。
