Step 5, judging whether the ore belt is changed relative to the previous round after the model algorithm is calculated, and if so, carrying out step 6; if no, performing step 7;
and 6, the algorithm gives a moving direction and a moving distance after accurate calculation, the moving distance is accurate to millimeter, the pivot platform in software sends an instruction to the motion control system, and the control system drives the motor to drive the ore receiving plate to move to a designated position. Through the understanding of the on-site ore dressing condition and the ore belt change frequency, the system software central platform sets 2min to control the camera to collect the pictures of the ore belt on the surface of the on-site cradle bed once, the algorithm is calculated once, the ore belt can send corresponding instructions when the upper wheel has the change software central platform, and then the direction and the distance of the ore plate are adjusted.

The computer and the 4G gateway can be connected through a network cable, and can also be communicated by using a SIM card, and the 4G gateway is connected with the camera through the network cable.
When the intelligent system starts to work, firstly, the system sends an instruction to a wireless gateway, the gateway sends a command signal to a camera, the camera collects images of the ore strips on the cradle bed surface, the collected images are transmitted to a system control platform through a 4G gateway, the system is provided with an image preprocessing module, firstly, the collected information images of the cradle strips are preprocessed, then the preprocessed images of the cradle strips are transmitted to a trained data model, the model carries out data comparison, analysis, calibration and line drawing on the image information, concentrate strips, secondary concentrate strips, middling strips and tailing strips are divided one by one, then an output result image is output, and the system sends an instruction to a motor control system according to the change condition of the ore strips, so that corresponding adjustment is carried out on a docking plate to finish the index set by a factory. The system can set the image acquisition frequency according to the requirement so as to achieve the purpose of real-time monitoring.
The cradle for mineral separation is a common device for separating fine ore. Is usually composed of a bed surface, a frame and a transmission mechanism. In addition, a water flushing tank, a mineral feeding tank and the like are arranged, the whole bed surface is supported or lifted by a frame, the bed surface is arranged on the frame, and a slope adjusting machine is arranged at the bottom of the frame. The inside of the bed head is provided with a lubrication system and a motor as a transmission mechanism, and the bed surface is provided with a bed bar. The bed head is connected with one end of the bed head. The utility model discloses a mineral shaking table is common equipment, and the current shaking table equipment that adopts this time also does not carry out technical improvement to it, and its concrete connection structure and theory of operation are not repeated here.
