Intelligent speed regulating method and system for mine crusher

Abstract

The invention discloses an intelligent speed regulating method and system for a mine crusher. The method comprises the following steps: 1, mounting two photography instruments above a feeding hole of the crusher, wherein the photography instrument I is oriented to the feeding hole of the crusher, and the photography instrument II is arranged on the same horizontal plane as the photography instrument I, and is perpendicular to the shooting direction of the photography instrument I; 2, collecting video images by the photography instruments, and carrying out image processing; 3, calculating the total mass of ore at current moment by three-dimensional edges of the ore, detected by the two photography instruments; 4, obtaining a characteristic curve that the ore quality adapts to the rotating speed of a motor through an experiment, and inputting the determined logic judgment method into a PLC; and 5, automatically adjusting the rotating speed of the motor of the crusher by the controller according to the quality range of the ore. The total mass of the fed ore is obtained through the two photography instruments, so that the total mass adapts to the lowest rotating speed; the lowest energy consumption when the crusher meets the working requirements is ensured; and the service life of the crusher is prolonged.

Description

technical field [0001] The invention relates to a method for intelligent speed regulation of a mining crusher, belonging to the technical field of mining machinery monitoring. Background technique [0002] Mining crushers are mainly used for crushing various types of stone, and can be widely used in many departments such as mines, smelting, building materials, highways, railways, water conservancy and chemical industries; mining crushers are required for crushing raw ore to grinding process Particle size so that the useful minerals can be separated into monomers. [0003] At present, mining crushers are generally used in conjunction with a screening mechanism. The raw ore first passes through a differential mechanism to initially screen the size of the coal block, and the smaller raw ore is directly sent to the loader, and the larger raw ore needs to be crushed by the crusher before being sent. to the loader. Since the size and quality of the raw ore reaching the crusher i...

Problems solved by technology

[0004] In the prior art, in order to control the quality of raw ore input into the crusher, the speed of the feeder and the rotation speed of the main motor are adjusted through the electronic belt scale. Electronic belt scales, and it is difficult to guarantee the accuracy of electronic scales in harsh environments, so it is not suitable for controlling the raw ore quality of crushers in mines
