The invention discloses a double-funnel anti-blocking feeding coal bunker of a thermal power plant in the technical field of feeding coal bunkers. A large coal bunker and a small coal bunker which are of a conical barrel structure and are coaxially sleeved inside and outside are included, and an annular interlayer space between the large coal bunker and the small coal bunker is a feeding channel. A plurality of pushing mechanisms which are distributed in an annular array manner are arranged in the feeding channel, and each pushing mechanism comprises an outer conveying belt device and an inner conveying belt device. The inner side of the large coal bunker is further provided with a plurality of hydraulic connecting rod sets which are distributed in an annular array mode and used for being connected, installed and controlling the opening degree of an upper end opening of the small coal bunker in a traction mode so as to control the sectional area of a feeding end opening of the feeding channel. The upper end o
