Conveying belt blockage protection device

The conveying belt blockage protection device comprises a conveying bin, a conveying mechanism and a bottom bin, the outer side of the top of the conveying mechanism and the inner side of the bottom of the conveying bin are fixedly installed, the outer side of the bottom of the conveying mechanism and the outer side of the top of the bottom bin are fixedly installed, and the conveying mechanism comprises a guide frame, an inclined side frame and a conveying assembly. According to the invention, the change of the output value of the pressure sensor caused by the increase of materials adhered to the surface of the conveying belt and stress deformation can be found in time, so that the problems that the whole discharge port is blocked and overflows materials and even the belt is on fire due to continuous friction caused by excessive materials due to the fact that the discharge port is blocked and is not shut down in time are solved; and when more and more materials adhere to the surface of the conveying belt, th
