Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing.

[0032] A method for intelligent speed regulation of a mining crusher, the steps are as follows,

[0033] Step 1: Install two cameras above the feed port of the crusher 1, the camera I4 is facing the feed port of the crusher, and the camera II5 is installed on the same level as the camera I and perpendicular to the shooting direction of the camera I ; Camera I and camera II are explosion-proof network cameras.

[0034] Such as figure 1 As shown, the XYZ three-dimensional coordinate system is established on the layout drawing, the camera I can take images in the YOZ plane, and the camera II can take images in the XOZ plane, and the color distribution of the ore on the current crusher can be obtained through these two cameras picture.

[0035] Step 2: Two cameras collect video images at the same time and perform image processing. The steps are as follows:

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...
