Ore distribution vehicle ore blocking alarm device

The utility model belongs to the technical field of belt conveyor distribution vehicles, and particularly relates to an ore distribution vehicle ore blocking alarm device. The ore distribution vehicle ore blocking alarm device comprises a control loop of a control device and is characterized in that two ore blocking sensing devices are arranged above ore distribution vehicle ore unloading mechanisms on the two sides of an ore distribution vehicle respectively, a limit switch is arranged at the tail of an ore belt conveying mechanism of the ore distribution vehicle, an audible and visual alarm unit is arranged on the ore distribution vehicle, and a PLC, a change-over switch and an intermediate relay are arranged on the control loop; each ore blocking sensing device comprises a supporting base, a receiving hopper arranged on the supporting base, a swing ore baffle arranged above the receiving hopper, and a leaking stoppage switch; each swing ore baffle abuts against a feeler lever of the corresponding leaking stoppage switch. The ore distribution vehicle ore blocking alarm device has the ore blocking prevention function, when ore blocking occurs in the ore distribution vehicle, the ore distribution vehicle can automatically move to be separated from the peak of a lower material level and an audible and visual alarm prompt signal is sent out at the same time, so that material scattering is reduced, the work environment is improved, labor intensity is relieved, and production efficiency is improved.
