Automatic cutting control system and automatic cutting control method for coal cutter

Abstract

The invention discloses an automatic cutting control system and an automatic cutting control method for a coal cutter. The control system comprises a controller, a data storage device, a working condition detection apparatus for the coal cutter and a control host. The working condition detection apparatus for the coal cutter comprises a walking displacement detection unit, an angle detection unit one for detecting the swing angle of a right rocker arm, an angle detection unit two for detecting the inclination angle of a working face, an angle detection unit three for detecting the swing angle of a left rocker arm, and an angle detection unit four for detecting the upward or downward angle of the coal cutter. A left height adjustment oil cylinder and a right height adjustment oil cylinder are both controlled by the controller. The control method comprises the steps of: 1) learning and memorizing the cutting trace of the currently working coal seam; 2) accomplishing the automatic coal cutting according to the memorized trace, and adjusting the memorized trace in real time; 3) repeating step 2) until all the exploration processes of the currently working coal seal is finished. The system of the invention is advantageous by a simple circuit, a reasonable design, a convenient control method, and good application effect, and can realize the automatic cutting control of the coal cutter.

Description

technical field [0001] The invention belongs to the technical field of shearer cutting control, and in particular relates to an automatic cutting control system and an automatic cutting control method for a coal shearer. Background technique [0002] my country's thin coal seam has abundant recoverable reserves, relatively stable storage conditions, and good coal quality. In recent years, the mining of thin coal seams has gradually increased, and thin coal seams have gradually become the main coal mining seams. But at present, the degree of mechanization suitable for thin coal seam and thin coal seam mining is still relatively low, and most of them are mined by blasting, which not only has low output, but also has many accidents, the working environment of workers is harsh, and there are great safety hazards. Thereby along with increasingly paying attention to thin coal seam mining, be badly in need of solving above-mentioned thin coal seam mining problem. To solve the prob...
