Abstract

The invention relates to a compound rotary cutting mining machine, which has long service life, high efficiency and low power consumption, and is characterized in that at least one or more motors are arranged in the drill bit or the drum of the mining machine, and the drill bit or the drum The external high-pressure air or high-pressure liquid is powered by the motor to drive the pick seat to rotate and impact, which improves the efficiency and reduces the cost.

Description

Technical field: [0001] The invention relates to a composite rotary cutting mining machine, which is used in mining and roadway excavation of mechanical equipment such as mining and drilling rigs. Background technique: [0002] At present, the excavator drill bits used in coal mining equipment are picks fixed on the drill bit. Although some picks can rotate, they are not actively rotating and cutting, so the resistance of the shearer, roadheader or drilling rig is too large when working , causing equipment damage, wasting a lot of power and material resources, and increasing production costs. Invention content: [0003] The present invention is proposed in view of the above-mentioned problems, and aims to provide a compound rotary-cut mining machine. On the basis of the original main engine, the compound rotary-cut mining The host connection of the excavator achieves high efficiency, low resistance, high heat dissipation efficiency, long life, remarkable energy saving eff...
