Background

It is well known that the connection between the various devices in a sampling system in the field of coal sampling relies on a coal drop tube connection. For the coal with lower moisture content, the coal sample remained on the inner wall of the coal drop pipe in the sampling process is less. For the coal quality with higher moisture content, more coal samples adhere to the coal dropping pipe, particularly the coal samples pass through the crusher at the feed inlet and the discharge outlet of the crusher, and wet coal samples can be thrown to the side wall of the coal dropping pipe at the inlet and the outlet by the crushing hammer head rotating at high speed in the inner cavity of the crusher to form a compact adhesion layer, although the vibrator or the vibrating plate is arranged on the side wall, the adhered coal layers are more and more thick, and even the condition of blocking the whole coal dropping pipe frequently occurs. Thereby causing a blockage in the pipeline and causing a shutdown of the system. And the process of cleaning the blocked coal is time-consuming and labor-consuming. And can also cause mixing and have certain use limitations.
