The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

This example describes a zinc powder charging device that avoids adding agglomerated zinc powder to a mixing drum.

As shown in fig. 1, above the mixing drum 1, a feed pipe 2 transports zinc powder into the mixing drum 1 through a feed assembly 3.

The feeding assembly 3 is shown in fig. 2 and comprises a filter screen 3.1, a driven roller shaft 3.2, a roller 3.3, an orbit groove 3.4 and a driving roller shaft 3.5.

The filter screen 3.1 is arranged at the bottom of the box body of the feeding assembly 3 and is positioned above the feeding hole of the mixing drum 1 and used for filtering zinc powder. Track grooves 3.4 are respectively arranged on two opposite sides of the box body. The roller 3.3 is a hollow wheel, so that the weight of the roller 3.3 can be reduced, and the driving force is reduced. The outer teeth are arranged on the outer surface of the roller 3.3 in an encircling mode and are matched with the filter screen 3.1, so that the zinc powder block can be rolled, zinc powder adhered to the surface of the roller 3.3 can be scraped off in the rolling process, and the zinc powder adhered to the surface of the roller 3.3 is avoided. Two ends of the roller 3.3 are fixedly connected with a driven roller shaft 3.2 and a driving roller shaft 3.5 respectively, the driven roller shaft 3.2 and the driving roller shaft 3.5 are arranged in the track grooves 3.4 respectively and can roll along the track grooves 3.4 to drive the roller 3.3 to roll on the filter screen 3.1, and zinc powder blocks are rolled to prevent the zinc powder blocks from falling into the mixing drum 1.
