The invention discloses an overall weighing type raw coal bunker which comprises a raw coal bunker, reinforcing ribs, brackets, weighing sensors, a central feeding machine, a cone, a discharge arm, a chassis, a transmission device, a driving device and a discharge hole, wherein the raw coal bunker is a cylindrical raw coal bunker; the reinforcing ribs are mounted on the outer side of the raw coal bunker and fixed on the brackets; the weighing sensors are fixed on the brackets and are uniformly distributed on the raw coal bunker; the corn is arranged at the bottom inside the raw coal bunker; the chassis is arranged at the outlet in the bottom of the raw coal bunker; a fixed gap is formed between the corn and the chassis; the discharge arm is connected with the chassis and is mounted on the transmission device in an overall embedded manner; the driving device is arranged at the lower part of the transmission device and is connected with the transmission device; the discharge hole is formed in the bottom end of the central feeding machine. The overall weighing type raw coal bunker has the beneficial effects that a coal blocking phenomenon is greatly reduced, overall static weighing of the amount of the raw coal bunker is achieved, and the coal conveying precision can be improved.
