Mining machine walking meshing system with material releasing structure

Abstract

The invention relates to a mining machine walking meshing system with a material releasing structure. The mining machine walking meshing system comprises a track unit and a guide sliding shoe, whereina front bottom wear-resistant layer, a front side wear-resistant layer, a rear top wear-resistant layer, a rear side wear-resistant layer and a rear bottom wear-resistant layer are arranged on the guide sliding shoe; the track unit comprises a front vertical plate, a rear vertical plate and track teeth; the bottom surface and the front side surface of the front vertical plate are respectively incontact and matched with the front bottom wear-resistant layer and the front side wear-resistant layer; a step which protrudes backwards is arranged at the upper part of the rear vertical plate; the top surface of the rear vertical plate, the rear side surface of the step and the bottom surface of the step are respectively in contact and matched with the rear top wear-resistant layer, the rear side wear-resistant layer and the rear bottom wear-resistant layer; a first material releasing channel is arranged below a track tooth nest between the track teeth; and a second material releasing channel is arranged below the front vertical plate, the rear vertical plate and the track teeth. According to the mining machine walking meshing system, the adaptability of a drum-type mining machine guidesystem to high-hardness and high-lumpiness mineral aggregates can be improved, the guide system is prevented from being quickly worn and crushed, and the fault processing time is short.

Description

technical field [0001] The invention relates to a walking meshing system of a mining machine, which is especially suitable for the case where the ore material is in the form of blocks, and the existing guide slide shoes are obviously worn, especially the bottom hook of the existing guide slide shoes is severely worn, and belongs to the underground mining machinery technology field. Background technique [0002] When using a drum-type mining machine to mine high-hardness mineral materials, the reaction force (especially impact) generated by cutting hard mineral materials has a great impact on the walking engagement system of the mining machine, and the larger ore size makes the mining machine walking engagement system The adaptability (the faster the contact surface wears and crushes due to eccentric loads, the worse the adaptability) is facing severe tests, such as Figure 11 The walking meshing system of the existing structure shown, when encountering the high hardness at t...
