The invention discloses a method for improving the conveying efficiency of block ore or coal. The mined ore or coal is placed on the conveying surface of any position of the conveyor belt, and the initially placed ore or coal is squeezed on at least two rows of baffle plates. Until the baffle plate and the conveying surface of the conveyor belt move synchronously; then the ore or coal is continuously placed on the conveying surface at the bottom end of the conveyor belt for transmission. When the baffle plate and the conveying surface of the conveyor belt move synchronously, the baffle plate passes through The baffle conveyor belt is pulled on the conveyor belt guide frame to circulate and run. When the baffle plate runs from the outside of the conveyor belt guide frame to the conveyor belt inside the conveyor belt guide frame, the limit post under the baffle plate slides into the limit slot, and passes through the baffle plate. The hinge point of the conveyor belt of the material plate and the baffle plate, and the limit point of the limit column at the limit point of the limit slot are jointly limited, so that the baffle plate is unfolded on the conveyor belt to act as a material stopper, which can increase the transportation of ore or ore on the conveyor belt. Coal thickness, thereby improving transportation efficiency.

The invention discloses a conveying device for improving the conveying efficiency of massive ore or coal. The conveying device comprises a conveyor belt, a conveyor belt V-shaped bracket, stop plates,a stop plate conveyor belt and a conveyor belt guide rail bracket; the conveyor belt is laid on the conveyor belt V-shaped bracket in a V shape, and the V-shaped conveyor belt is provided with two conveying sides; and when the stop plates are ready to be taken away from the upper part of the conveyor belt by the stop plate conveyor belt, limiting columns under the stop plates can slide from a limiting slot to a V-shaped limiting slot, and then can be separated from the V-shaped limiting slot, so that the stop plates can rotate around hinge pins, and at this time, the stop plates are close tothe stop plate conveyor belt to be folded through limiting by a limiting plate, thus, the stop plates basically do not occupy the arrangement space of the conveying device, and the conveying device has the practical value. The conveying device solves the problem that when the massive coal or ore is conveyed by the V-shaped conveyor belt with an included angle, stop plates cannot be arranged on theconveyor belt, so that the conveying efficiency of the conveyor belt is low and potential safety hazards exist.
