Problems solved by technology

[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 damage to the equipment, wasting a lot of power and material resources at the same time, and increasing the production 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. Contents of the invention [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 savin...
