Belt conveying and screening production line

The utility model belongs to the field of ore screening, particularly relates to a belt conveying and screening production line, and aims to solve the problem that impurities are easily attached to the surface of a conveyor belt of an existing ore screening device in the using process, so that the conveyor belt is damaged. The screening machine is provided with a material inlet and a material outlet, the first conveying belt is connected with the material inlet of the screening machine and conveys raw materials for the screening machine, and the bottom of the screening machine is fixedly connected with a mounting frame for supporting the screening machine. Raw materials can be input into the screening machine through the first conveying belt, the raw materials screened by the screening machine fall into the surface of the second conveying belt, the raw materials are supplied to subsequent steps, and the problem that in the prior art, impurities are prone to being attached to the surface of a conveying belt fo
