The utility model relates to a reamer for geological exploration. The reamer for geological exploration comprises a belt and a drill stem, wherein the drill stem is supported by multiple cross rods to be fixedly connected to the center of the belt, multiple reaming rods are fixedly connected between the inner wall of the belt and the outer wall of the drill stem, multiple alloy blocks are evenly distributed on the lower end face of the belt, multiple alloy blocks are evenly distributed on the outer wall of each reaming rod, the reaming rods are arranged symmetrically relative to the center of the drill stem, the drill stem and each reaming rod are each of a hollow structure, the drill stem is communicated with the reaming rods, the multiple cross rods are distributed on an upper layer and a lower layer respectively and are arranged symmetrically relative to the center axis of the drill stem, each reaming rod comprises a supporting plate with an L-shaped end face and an oblique plate arranged on the inner sides of two straight plates of the supporting plate, a triangular hollow flow channel is defined by the oblique plate and the two straight plates of the supporting plate of each reaming rod, each hollow flow channel is communicated with the drill stem, multiple water outlets which are communicated with the corresponding hollow flow channel are formed in each oblique plate, and the alloy blocks are evenly distributed on the end face of one straight plate of each supporting plate. The reamer for geological exploration has the advantages that the reaming effect is good, and the reaming rods, the drill stem and the belt are connected highly stably.
