[0020] It should be noted that, in the coal transportation system of the fuel power plant, the coal drop pipe is often blocked by coal during the coal transportation operation. In order to solve this problem, manual clearing is usually used, which is inefficient and causes frequent unsafe accidents. Therefore, in order to solve the problem of frequent coal blockage in the coal drop pipe, the present solution operates through the motor 10 to make the chain 7 carry the connecting rod 8 to rotate in the coal drop pipe body 1, and the driving rod 9 protrudes from the connecting rod 8.
