The invention provides an anchor rod supporting combination device which can automatically push two anchor rods into a drill hole at the same time, improve the laying efficiency of the anchor rods, enable the anchor rods to adapt to different drill hole depths and ensure the anchoring quality. An anchor rod supporting combination device comprises a base, sliding seats and the like, and the upper sides of the left portion and the right portion of the base are connected with the sliding seats in a sliding mode. After the anchor rods make contact with the bottom of a drill hole, the upper closing wheels stop rotating, the middle ring stops rotating, at the moment, the force storage spring rebounds, the guide support is pulled to enter the scattering ring, the guide support is guided through the scattering ring, the belt is ejected out of the corresponding upper closing wheels through the belt |
