Description

Mining belt feeder tears detection device Technical Field The application relates to the technical field of belt conveyors, in particular to a mining belt conveyor tearing detection device. Background Belt scratch tearing on a belt conveyor is a common belt breakage mode, and in the process of conveying materials by the belt, the belt is the weakest place in the whole process of conveying materials due to belt scratch tearing caused by uneven stress, blockage of foreign matters and the like, and the belt cost occupies a larger proportion of the cost of conveying equipment, so that the fault can cause larger economic loss. To this, chinese patent application No. CN202220445070.8 discloses a belt tearing detection device, mainly through being used for obtaining the subassembly of making a video recording of the belt image of waiting to detect the belt conveyor in waiting to detect the belt conveyor top to and confirm the embedded industrial computer of waiting to detect the tearing situation of belt conveyor belt based on the belt image, thereby can realize the real-time detection to the tearing situation of belt based on the embedded industrial computer, just can confirm that the belt takes place to tear under the condition that the initial stage is torn to the belt does not take place to leak the material, promoted the instantaneity of belt tearing control. However, in the process of implementing the technical solution in the embodiment of the present application, the present inventors have found that at least the following technical problems exist in the above technology: 1. The camera shooting assembly is arranged above the belt, the belt is used for conveying materials, the surface of the belt can be piled up, the situation that the belt at the position covered by the materials is torn can not be shot, meanwhile, in the mining conveying process, a large amount of dust exists in the working environment, the normal shooting of the camera shooting assembly can be influenced under the condition that no dust removing structure exists, the dust is attached to the surface of the camera, the shooting picture is fuzzy, and finally the detection structure can be influenced; 2. The mining conveyor belt generally runs faster, and a camera shoots a belt in high-speed movement, so that if the shutter speed of the camera is insufficient, the camera is easy to shoot paste, and fine cracks are not easy to detect through a photo.
