Problems solved by technology

[0008] It can be seen that the setting of the above-mentioned mining height system allows the operator to easily know the height of the cutting drum without leaving the cab or protruding the body out of the cab. The modification increases the complexity of the whole machine, and the versatility is poor. At the same time, due to the influence of the transmission device, the accuracy is also poor, and there are still large errors

Abstract

The invention discloses a mining height system used for a coal mining machine. The system comprises a detection device (1), a control device (2) and a display (3), wherein the detection device (1) is used for detecting the position and the posture of a cutting arm of the coal mining machine to obtain a position and posture signal; the control device (2) is used for receiving the position and posture signal and obtaining a height signal of a cutting roller of the coal mining machine according to a preset policy; and the display (3) is arranged in a cab of the coal mining machine and used for receiving the height signal and displaying the height value of the cutting roller. The mining height system guarantees that an operator can accurately obtain the height of the cutting roller in the cab, thereby guaranteeing the safety of the operator; and meanwhile, the structure reformation to the coal mining machine is less, thereby the generality is improved, and the cost is reduced. The invention also discloses a coal mining machine comprising the mining height system.

Description

technical field [0001] The invention relates to the technical field of coal mining equipment, in particular to a mining height system. The invention also relates to a coal shearer comprising the above-mentioned mining height system. Background technique [0002] my country is the main coal-producing country in the world, and the total number of coal mines exceeds the sum of the number of coal mines in all other countries in the world. At present, comprehensive mechanized coal mining has become the main method of mining coal seams. [0003] Comprehensive mechanized coal mining refers to the entire production process of the coal mining face, including coal breaking, coal loading, coal transportation, support, goaf treatment, mining roadway transportation, and excavation. The complete set of equipment for fully mechanized mining face mainly includes: shearer, scraper conveyor and hydraulic support. Shearer is a coal breaking equipment for comprehensive mechanized coal mining....
