Coal gangue sorting system based on image data processing

Abstract

The invention relates to a coal gangue sorting system based on image data processing. The coal gangue sorting system based on image data processing comprises a supporting shell, supporting seats, driving rollers, a conveying belt, a traction mechanism, a distribution mechanism, a linkage mechanism, a sorting mechanism and a driving motor, wherein the two ends of the supporting shell are respectively provided with the supporting seats; the driving rollers are installed between the two supporting seats on the same side; the driving motor is installed on the side wall of one supporting seat; an output shaft of the driving motor is connected with the driving rollers; the outer walls of the two driving rollers are sleeved with the conveying belt; the traction mechanism is arranged on the outer wall, located at one end of the driving motor, of the corresponding supporting seat; the distribution mechanism is arranged in the middle of the supporting shell; and the linkage mechanism is arranged on the inner wall of the supporting shell. According to the coal gangue sorting system based on image data processing provided by the invention, coal gangue which is disorderly distributed on the conveying belt can be arranged to be transversely and parallelly distributed, so that the coal gangue falling from the conveying belt is located on one side of each air tap, so that each air tap can be ensured to accurately sort, and the occurrence of the phenomenon of omission of sorting by the equipment is avoided.

Description

technical field [0001] The technical field of coal mining equipment of the present invention is specifically a coal gangue sorting system based on image data processing. Background technique [0002] Coal gangue is solid waste discharged during the coal mining process and coal washing process. It is a black-gray rock with low carbon content and harder than coal that is associated with coal seams during the coal formation process. Including the excavation gangue during the roadway excavation, the gangue extracted from the roof, floor and interlayer during the mining process, and the gangue picked out during the coal washing process. The coal gangue sorting system is a special equipment for screening gangue. It mainly collects images of coal and gangue through camera or ray equipment, and then analyzes the data by computer to screen out coal and gangue, and then controls the gas flow through computer. Nozzle, the high-pressure gas is ejected through the air nozzle, and the ej...

Problems solved by technology

[0003] However, a kind of coal gangue sorting system based on image data processing in the current market will have the following problems during use. The pressure of the gas ejected from the gas nozzle is relatively high. Generally, the diameter of the gas nozzle is small, that is, the working radius is small. When the offset between the coal gangue on the conveyor belt and the gas nozzle is large, the gas nozzle cannot screen out the gangue , it is easy to miss the selection; b. When the coal gangue falls on the conveyor belt in the coal gangue sorting system, the coal gangue is disorderly distributed relative to the conveyor belt, which seriously affects the sorting accuracy of the gas nozzle
