[0002] Cement is composed of a variety of substances. In the process of cement production, it is often necessary to mix cement materials. Usually, a cement mixing device is used to mix cement raw materials. However, if the device is opened directly to collect the mixed materials after mixing, cement dust is likely to float, causing air pollution. To avoid the above situation, a patent search shows that a Chinese utility model patent, authorization announcement number "CN217943759U", discloses a cement stirring and mixing device, including a mixing box, a straight rod is welded to the upper end of the mixing box, a through groove is opened at the lower end of the straight rod, a fixing rod is provided in the inner cavity of the through groove, and a brush plate is bonded to one side of the fixing rod.
[0003] The above technical solution can maintain the cement mixing equipment by setting a fixed rod, a spring, an ash suction head, a servo motor, a scraper and a pull rope. The brush plate on the fixed rod can clean the ash suction head back and forth, thereby cleaning the cement raised during the mixing process and attached to the ash suction head, thereby saving the trouble of manual cleaning and reducing the waste of cement. However, its air pump vacuums vertically downward, and its vacuum range is relatively limited and not detailed enough, especially at the end far away from the ash suction head, where the floating dust is more difficult to clean, so there is a phenomenon of unsatisfactory cleaning effect.
