In conclusion, the invention can efficiently and rapidly produce fine-fraction, medium-fraction and coarse-fraction tailing sand finished products, has low cost, high efficiency, stable operation, environmental protection and reliability, and more specifically:

The tailing taking device is erected above the tailing throwing belt conveyor from one side of the tailing throwing belt conveyor, the track laying direction is at a certain angle with the conveying direction of the tailing throwing belt conveyor, the angle can be 45 degrees or other angles, then the track car is pulled to the position above the tailing throwing belt conveyor through the traction device, the lower edge of the vertical plate is hovered at the position close to the top surface of the tailing throwing belt conveyor, so that when tailings on the tailing throwing belt conveyor reach the vertical plate position, the vertical plate is blocked, the tailings fall from the tailing throwing belt conveyor along one side of the vertical plate, so that the tailing taking operation in the first link in the tailing recycling process is realized, the track car can be pushed and pulled to slide on the track through the traction device in the tailing taking process, the relative position of the vertical plate above the tailing throwing belt conveyor can be flexibly regulated and controlled, the free control of the amount in unit time is realized, the working efficiency is remarkably improved according to the requirement, and the problem that the taken tailings are not polluted again before the tailings are stored and reused is avoided. In addition, the two rails are arranged, so that the structure is more stable, the running is more reliable, and the power device can be an electric device or a manual device and is not limited.

The blanking conveying device is preferably a metering belt conveyor, which is a belt conveyor type conveying device with a weighing function, and is not described in detail herein.
