Anti-blocking device of belt conveyor

The utility model belongs to the technical field of conveyors, particularly relates to an anti-blocking device of a belt conveyor, and aims to solve the problems that in the prior art, when a sensor is installed, the requirement for the position is accurate, the structural strength of a whole hopper is reduced, and after an anti-blocking sensor is installed, the anti-blocking sensor is damaged. In order to solve the problems that in the prior art, the position height is fixed and an anti-blocking sensor is difficult to maintain, the following scheme is provided: the device comprises a funnel and a mounting frame, the mounting frame is located on one side of the funnel, the mounting frame is in transmission connection with a conveying belt, one side of the conveying belt extends into the funnel, and the conveying belt is used for conveying materials into the funnel; according to the novel anti-blocking device for the belt conveyor, the detection sensor can be moved to the outer portion of the transfer hopper,
