Embodiment 1

[0038] as attached figure 1 Shown: a coal and gangue sorting system, including a vibrating coal feeder 1, a main conveyor belt, an identification module, a coal and gangue separation device, a gangue returning conveyor belt 9 and a first coal conveyor belt 10:

[0039] The vibrating coal feeder 1 is located at the starting end of the main conveyor belt, and is used to transport the coal gangue mixture to the main conveyor belt, and the coal gangue includes coal 12 and gangue 13 .

[0040] The main conveyor belt is used to convey the coal gangue mixture; the main conveyor belt includes the first conveyor belt 2 and the gangue conveyor belt 8, and the vibrating coal feeder 1 is located at the starting end of the first conveyor belt 2 and the end of the first conveyor belt 2 Below is the starting end of gangue conveyor belt 8, the identification module is located above the starting end of gangue conveyor belt 8, and the coal and gangue separation device is located at one side of ...

Embodiment 2

[0067] as attached image 3 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the lighting module 6 is a multi-color lighting lamp, and the control module 5 controls the color change of the lighting lamp according to the shooting frequency of the shooting module 3, so The photographing module 3 is also used to perform secondary photographing of the target object on the gangue conveyor belt 9 to obtain a secondary photographed image; the distinguishing module 4 is also used to put the secondary photographed image into the gangue 13 model for identification , to obtain the degree of confidence of the target object in the image; the second drive device 14 and the second coal conveyor belt 15 are also included in the present embodiment; the second drive device 14 is electrically connected with the control module 5, and the controller also uses In determining the target object whose confidence level is less than the set value in the secon...

Abstract

The invention belongs to the technical field of coal and gangue separation, and discloses a coal and gangue separation system and an identification method. The coal and gangue separation system comprises a vibration coal feeder, a main conveyor belt, an identification module and a coal and gangue separation device, wherein the vibration coal feeder is located at the conveying starting end of the main conveyor belt and used for conveying a coal and gangue mixture to the main conveyor belt, and the coal and gangue mixture comprises coal and gangue; the main conveyor belt is used for conveying the coal and gangue mixture; the identification module is located right above the main conveyor belt and used for shooting a coal and gangue mixture image, putting the shot coal and gangue image into a gangue model, identifying gangue in the image and obtaining position information of the gangue; and the coal and gangue separation device is located at one side of the main conveyor belt and used for screening out gangue according to a confidence coefficient, obtaining the position information of the gangue and separating out the gangue before the coal and gangue mixture reaches the tail end of the main conveyor belt, so that the problems that in the prior art, a gangue identification method is harmful, equipment is complex, the equipment cost is high, and maintenance is difficult are solved.

Description

technical field [0001] The invention belongs to the technical field of coal gangue sorting, and in particular relates to a coal gangue sorting system and an identification method. Background technique [0002] Gangue is a black-gray rock with low carbon content and harder than coal that is associated with coal seams during the coal-forming process. Because the escape or leaching of sulfide in gangue will pollute the atmosphere, farmland and water bodies, and gangue hills will spontaneously ignite and cause fires, or collapse in the rainy season, silting up rivers and causing disasters. Therefore, in the coal mining process, coal gangue needs to be separated The selection will not only help to improve the quality of raw coal, but also backfill the gangue to avoid environmental hazards caused by spontaneous combustion, rain, and mudification of the gangue. [0003] The coal gangue identification methods in the prior art mainly include the density identification method, the ra...
