Abstract
The invention provides a belt conveyor head portion blocking and overflowing automatic stop (alarm) device, and belongs to the technical field of belt conveying. The normal production of an enterprise is directly affected by material bulk depositions, belt breaking or a fire accident, wherein the material bulk depositions, the belt breaking or the fire accident are caused by the blocking of a feeding pipe arranged on the head portion of a belt conveyor. The belt conveyor head portion blocking automatic stop (alarm) device is installed on the head portion of the belt conveyor. When the weight of blocking and overflowing and scattered materials collected by an inner hopper of the device reaches a certain value, a support plate compresses springs downward until the springs contact micro switches depending on the self gravity of the support plate. The micro switches are enabled to act on a tripping relay of a driving motor of a conveying belt to stop the operation of the conveying belt immediately. Blocking and overflowing degree is reduced to the lowest, and therefore the expansion of an accident is avoided.
