The invention provides a novel aluminum alloy fusion casting sampler. The novel aluminum alloy fusion casting sampler comprises a sampling bottom plate, a sampling chamber, a left sampling clip, a right sampling clip and a pouring device, wherein a bottom plate handle is arranged on one side of the sampling bottom plate; a rotating shaft is arranged on the other side of the sampling bottom plate;the left sampling clip and the right sampling clip are rotatably connected to two sides of the sampling bottom plate through the rotating shaft; the bottom parts of the left sampling clip and the right sampling clip both make contact with the top surface of the sampling bottom plate; when the left sampling clip, the right sampling clip and the sampling bottom plate are folded, the sampling chamber is formed, and the pouring device is arranged on the top of the sampling chamber; the pouring device comprises a pouring hole, a filter screen and a filter residue box. According to the novel aluminum alloy fusion casting sampler disclosed by the invention, through the arrangement of the sampling chamber, sample parts to be sampled are smaller, so that materials can be saved and the waste can bereduced; through the arrangement of the left sampling clip and the right sampling clip, the pouring is conveniently carried out, and accidental injury to people is avoided; through the arrangement ofthe filter screen, molten aluminum for performing fusion casting and sampling can be effectively filtered, and the purity of the molten aluminum is improved.
