Belt conveyor material flow detection device and detection method thereof

The invention discloses a material flow detection device for a belt conveyor and a detection method thereof, and the device is characterized in that a fixed frame is located above a belt of the belt conveyor, and the fixed frame is fixed on supports at the two sides of the belt; the horizontal adjusting frame is connected with the top of the fixing frame through a positioning adjusting device, and the positioning adjusting device is used for adjusting the horizontal adjusting frame to a preset position in the belt moving direction; the vertical adjusting frames are arranged at different positions of the horizontal adjusting frame respectively, any vertical adjusting frame is provided with a sensor used for detecting materials, and any sensor is arranged over the materials. The controller is respectively connected with the plurality of sensors; in response to a material passing signal fed back by the plurality of sensors, the controller starts the water pump to perform watering operation.
