Problems solved by technology

However, the previous automatic cutting control methods for coal shearers can only perform automatic memory cutting on the straight section of the working face, and cannot cope with complex and changeable coal cutting processes. Frequent manual intervention is required at the nose and tail of the shearer, and Poor use effect, single function

Embodiment Construction

[0053] Such as figure 1 and figure 2 As shown, the teaching reproduction automatic cutting control method of the medium-thick coal seam roller shearer of the present invention includes the following steps:

[0054] Step 1. Automatic cutting and teaching of the drum shearer: along the length direction of the mining area of ​​the medium-thick coal seam, use the drum shearer control system to control the drum shearer to carry out layered mining of the coal seam to be mined from front to back ; In the layered mining process, the mining methods of the two coal seams connected to each other before and after the coal seam working face to be exploited are all the same;

[0055] The drum shearer control system includes a controller 8 and a memory 14 connected to the controller 8, the input of the controller 8 is connected with a data processing unit 7, and the input of the data processing unit 7 is connected with a left rocker arm mining height Detection module 4, right rocker arm m...

Abstract

The invention discloses a demonstration and playback control method for automatic cutting of a drum shearer for medium-thickness coal seams. The demonstration and playback control method includes 1, demonstration of automatic cutting of the drum shearer, and 2, playback of automatic cutting of the drum shearer. The step 2 includes 201, initializing a control system of the drum shearer; 202, judging whether the drum shearer is located at the tip or not; 203, playing back automatic cutting of the left end of the drum shearer; 204, playing back automatic cutting of the right end of the drum shearer. The demonstration and playback control method has the advantages that demonstration of the cutting process of the drum shearer for the medium-thickness coal seams covers necessary processes of bevel feeding, triangle coal cutting, float coal cleaning and coal cutting and excavating during travelling, so that manual interference is reduced greatly, automatic coal excavating requirements in coal excavation of the medium-thickness coal seams are met, and full-automatic control efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of automatic cutting control of coal shearers, and in particular relates to an automatic cutting control method for teaching and reproduction of a medium-thick coal seam drum shearer. Background technique [0002] Promoting the energy revolution and orderly building a safe, green, and efficient energy system have become the "new normal" of my country's energy development. Apply the automation technology revolution to the coal mine energy industry to promote its development, especially the fully-mechanized mining face. The fully-mechanized mining face is the front line of work and the working environment is harsh; Improving safety performance and automation of fully mechanized mining equipment are the goals pursued by the coal industry; the current direct recognition technology of coal-rock interface is not yet mature, and memory cutting, as an indirect recognition technology of coal and rock, has developed r...
