Problems solved by technology

In addition, due to the large dust and harsh working conditions in mining operations, the impact on the hydraulic system is large. Simple hydraulic control not only cannot control the normal operation of the entire equipment, but also the hydraulic components in the simple hydraulic control circuit are scattered and low in integration. High failure rate and short service life

Abstract

A roll-cutting type continuous mining machine comprises a car frame body, a cutting mechanism, a star wheel type loading mechanism, a scraper conveyor, a belt conveyer, an operating arm lifting oil cylinder, a belt conveyer rotary oil cylinder, a belt conveyer lifting oil cylinder, a hydraulic control system, a power supply system and a PLC (Program Logic Controller) control system, wherein the car frame body is equipped with a travel pedrail assembly and a cab, and the travel pedrail assembly comprises a left travel motor and a right travel motor; the scraper conveyor is obliquely mounted, the rear end of the scraper conveyor is hinged onto the car frame body, and a drive roller of the scraper conveyor is driven by a scraper hydraulic motor; the star wheel type loading mechanism is mounted at the front end of the scraper conveyor; a shoveling plate lifting oil cylinder is arranged between the star wheel type loading mechanism and the car frame body; a star wheel of the star wheel type loading mechanism is driven by the star wheel hydraulic motor. The mining machine not only can achieve continuous operation of cutting and loading, and has the advantages of large mining area, high mining working efficiency, low fault rate, less dust in the mining process, long service life and the like.

Description

technical field [0001] The invention relates to the technical fields of surface mining and engineering machinery, in particular to a rolling-cut continuous excavator. Background technique [0002] The traditional open-pit mining techniques are perforation blasting, single-bucket excavation, and forklift loading and transportation. The mined minerals vary in size and quality, requiring secondary crushing, screening, and secondary transport. Not only the mining production efficiency cannot be improved, but also the workload is large and the production cost is high. In response to the above problems, some open-pit mining equipment has been developed at home and abroad in recent years. For example, the patent number is: 201120236728.6, a drum side-mounted open-pit continuous coal mining machine, which includes a cutting mechanism, a reversible coal retaining mechanism, a hydraulic lifting device for the cutting mechanism, an operating room, a scraper conveyor, and a main frame...
