The invention discloses an insulated boot dry test steel ball filling box. The box comprises a shell body. An upper end of the shell body is provided with a steel ball storage bin. A lower end of thesteel ball storage bin is provided with a lower ball groove. The shell body is provided with an insulated boot placing bin. A lower side end of the insulated boot placing bin is provided with a flat plate. An upper end of the flat plate is provided with a main box. The main box is installed on an upper end of the flat plate in a contact mode, and two side ends are contacted and connected with theshell body. An inner side of the main box is provided with a steel ball guiding groove. By using the insulated boot dry test steel ball filling box, during ball adding, one test person stamps on a pedal of a pedal mechanism on one foot to complete selection of a same amount of steel balls to be filled. After the test person releases his or her foot, the same amount of steel balls enter an insulated boot placing bin channel from an internal portion of a translation bin under a gravity effect, and finally falls into an insulated boot. Then, a filling process of the single insulated boot is completed. Integral operation is comfortable and a workload is reduced.
