The invention relates to a briquette coal box, which is composed of a chassis, side walls, an upper cross beam, lifting hanging shafts, insertion boards, and insertion board guide grooves. The briquette coal box has no front and rear end plates, and the two side walls are perpendicularly fixed to two sides of the chassis along the long sides of the chassis; the cross section, perpendicular to thelength direction, of the briquette coal box has a concave structure; the two side walls are fixedly connected by the upper cross beam; and the insertion board guide grooves are symmetrically disposedin the side walls, the length of the insertion board guide grooves is equal to the length of the side walls, and the insertion boards are inserted into the insertion board guide grooves. The object ofthe present invention is to solve the problem of how to realize the automatic layer-by-layer stacking of the briquette coal.
