[0002] In the process of coal transportation in thermal power plants, the phenomenon of coal blockage in the coal fall occurs from time to time. Once the coal blockage occurs, if the coal blockage is not found and dealt with in time, it will cause coal to leak out of the barrel, and several tons of coal will be spilled in an instant. Coal is also a heavy physical work, which is time-consuming and labor-intensive and directly affects the normal production, and may damage the equipment in severe cases
The existing detection devices in China are contact type, which mainly include: valve type sensor, screw type sensor and far infrared sensor. The disadvantages are: the valve type and the screw type are easy to be damaged because they are installed in the coal fall; The far-infrared type has a lot of dust in the working environment, so it often breaks down and cannot work normally

Description
technical field [0001] The invention relates to a conveying device of a tape machine, in particular to a device for detecting the conveying state. Background technique [0002] In the process of coal transportation in thermal power plants, the phenomenon of coal blockage in the coal fall occurs from time to time. Once the coal blockage occurs, if the coal blockage is not found and dealt with in time, it will cause coal to leak out of the barrel, and several tons of coal will be spilled in an instant. Coal is also a heavy manual work, which is time-consuming and labor-intensive and directly affects the normal production, and may damage the equipment in severe cases. The existing detection devices in China are contact type, which mainly include: valve type sensor, screw type sensor and far infrared sensor. The disadvantages are: the valve type and the screw type are easy to be damaged because they are installed in the coal fall; The far-infrared type has a lot of dust in the ...
