[0025] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0026] like Figure 1-10 As shown, the automatic weighing device comprises a cylindrical shell 1, a feed port 2 opened at the upper part of the shell 1, a discharge port 3 opened at the lower part of the shell 1, a rotating shaft 4 rotatably arranged in the shell 1, a fan blade 5 arranged on the rotating shaft 4, a driving member 6 for driving the rotating shaft 4 to rotate, and a scraper mechanism;

[0027] The scraper plate mechanism comprises a plurality of scraper units 7 arranged along the rotating shaft 4 and the fan blades 5, a support plate 8 connected to the scraper units 7, and a connector 9 connected to the support plate 8 for connecting to a push rod.

[0028] The automatic weighing device includes a plurality of scraping units arranged in a cylinder shell 1, and the scraping units are connected to a connector 9 through a support plate 8. After a certain period of use, when the fan blades 5 need to be cleaned, a push rod is used to penetrate into the cylinder shell 1 and push the push rod after connecting the connector 9, so that the scraping unit 7 moves along the rotating shaft 4 and the fan blades 5, and scrapes off the materials adhered to the rotating cylinder and the arms of the fan blades 5, thereby achieving the purpose of cleaning. The automatic weighing device of the utility model uses a connector 9 to connect the push rod, and the scraping unit 7 can be moved along the rotating shaft 4 and the fan blades 5 by pushing and pulling the push rod, so as to realize convenient cleaning of the rotating shaft 4 and the fan blades 5, facilitate accurate material unloading in the later stage, and indirectly improve production efficiency.
