PROBLEM TO BE SOLVED: To provide an automatic measuring device of heavy metal concentration capable of preventing scattering of hazardous materials in ash. SOLUTION: The automatic measuring device includes: an ash collecting container 14 capable of storing the ash falling in a chute 1 disposed movably between an ash collecting position (α) in the chute 1 and an ash discharge position (β) in a discharge passage 4 by a cylinder apparatus 12 via a supporting member 11, in a take-out passage 3 of an ash discharge passage 2, which is connected to the side wall part of the chute 1 and consists of the take-out passage 3 and the discharge passage 4; and an X-ray measuring device 5 for measuring the heavy metal concentration in the ash in the container 14 disposed on the upper wall part of the take-out passage 3. The ash collecting container 14 is swingably supported on the front edge side of the supporting member 11 via a supporting pin 13 and the rear edge side is supported by the bottom wall part of the take-out passage 3 so that the container 14 is kept in a horizontal posture when moved to the ash collecting position(α), and the ash in the container 14 is discharged by keeping the container 14 in a vertical posture via a slope face arranged in the take-out passage 3 side when moved to the ash discharge position (β).
