Abstract: Disclosed is a back-stop protective device for a conveying belt of a belt conveyor. The back-stop protective device comprises a slide block back-stop plate, a back-stop support plate, a balance adjustment block, a back-stop liner plate support frame, a support beam, a left support frame and a right support frame. The back-stop protective device is characterized in that the left support frame and the right support frame are arranged in parallel; the support beam is connected with the upper end of the left support frame and the upper end of the right support frame; two articulated shafts are installed on the support beam; two balancing poles penetrate through the articulated shafts and are installed on the articulated shafts; the balance adjustment block is installed at the upper ends of the balancing poles; the back-stop support plate is fixedly installed at the lower ends of the balancing poles; the slide block back-stop plate is installed under the back-stop support plate; the left support frame and the right support frame are of the same structure; the right support frame is composed of a right oblique supporting frame and a right frame; the fixed back-stop liner plate support frame is installed on a cross beam of the right supporting frame and a cross beam of a left supporting frame. According to the back-stop protective device, a lever balance principle is adopted; the whole belt face of an upper conveying belt body is directly braked in a back-stop mode; no matter what the tightness of the conveying belt is, as long as the upper conveying belt body slides downwards in the backward direction, a good braking function is achieved.
