Abstract

The invention relates to a self-walking surface mining machine with multiple cutting heads. The self-walking surface mining machine comprises a machine body, cutting head groups, a conveying device group, a material collection mechanism, a material shoveling mechanism, a dust suppression mechanism and a transportation connecting mechanism, wherein each of the two cutting head groups on the left and right sides of the machine body comprises one or more cutting heads, the cutting heads in each cutting head group are longitudinally and sequentially distributed, when each cutting head group comprises one or two cutting heads, roller large planes of one or two cutting heads are level, and when each cutting head group comprises at least three cutting heads, roller large planes of the bottommosttwo cutting heads are level, the roller large plane of each cutting head is closer to the front side than the roller large plane of the front cutting head from the third cutting head from bottom to top. According to the self-walking surface mining machine, the continuous cutting, breaking, collection, loading and outward conveying can be realized, and the self-walking surface mining machine is applicable to the full-seam mining of middle-thickness ore deposits.

Description

technical field [0001] The invention relates to a self-propelled open-pit mining machine, in particular to a self-propelled open-pit mining machine capable of continuous mining and continuous transportation with multiple cutting heads, which is mainly used to meet the mining needs of small and medium-sized mines. Background technique [0002] The conditions of different working faces of open-pit mines vary greatly, such as the thickness of some meters and some tens of meters, and the corresponding equipment is different. For the mining of thick ore seams, a large number of single-bucket excavators (such as hydraulic shovels and electric shovels) are currently used for mining, and at the same time, they are equipped with car transportation, crushers, and belt conveyors. Due to the large number of auxiliary supporting equipment in the working face, the maintenance workload is huge. , The problem of mining cost per ton of material and mining efficiency of single bucket excavato...
