Abstract

A disclosed coal-cutter roller automatic height-adjusting system determines the position and the attitude of a coal cutter under a working-face geographic coordinate system through a positioning attitude-determining device and a working-face crossheading end position calibrating device, and a height-adjusting control core processor fuses measure data into a working-face three-dimension geological digital model according to the coal-cutter coordinates, performs three-dimension space analysis in the working-face three-dimension geological digital model according to the position of the coal cutter, obtains the cut coal layer thickness and cut coal layer variation at the position of the coal cutter, and real-timely dynamically adjusts the cutting height of the coal cutter by combining address environment parameters including coal layer dirt band. The provided coal-cutter roller automatic height-adjusting system is capable of realizing automatic height adjusting of a coal-cutter roller.

Description

technical field

[0001] The invention relates to an automatic height adjustment system of a coal shearer drum, which belongs to the coal mining equipment technology. Background technique

[0002] The automatic height adjustment technology of the shearer drum is the core technology of the automatic control system of the shearer. At present, there are two main methods to realize the automatic height adjustment of the shearer: (1) automatic height adjustment of the shearer drum based on coal-rock interface recognition; (2) automatic height adjustment of the shearer drum based on memory cutting. The working principle of the automatic height adjustment of the shearer drum based on coal-rock interface recognition is to use a method to automatically identify whether the medium cut by the shearer drum is coal or rock to control the shearer height. Coal and rock automatic identification methods include natural γ-ray detection method, radar detection method, stress pick method, infrar...
