Anti-blocking mechanism and coal dropping pipe

The utility model discloses an anti-blocking mechanism and a coal drop pipe in the technical field of anti-blocking of coal drop pipes, and the anti-blocking mechanism comprises a vibration part, a support frame, a mounting assembly arranged outside the support frame, and a driving assembly arranged in the mounting assembly; the discharging component comprises a feeding cylinder and a crushing assembly arranged in the feeding cylinder, a first motor drives an impact block to continuously vibrate a pipeline, the effect of dredging coal in the pipeline is achieved, the pipeline transportation smoothness is improved, the risk that the pipeline is blocked is reduced to a certain degree, a second motor drives a crushing tool bit to work, and the crushing efficiency is improved. According to the coal smashing device, caked coal can be smashed, then the risk that the pipeline is blocked is further reduced through the pipeline, the falling coal can be buffered through the arrangement of the curved-surface sliding way
