Specific embodiment
In order to deepen the understanding to the utility model, the utility model is further described below in conjunction with embodiment,
The present embodiment is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.
A kind of powder rotor weigher according to shown in Fig. 1,2, including shell 1, motor 2,3 ring balance rotor 4 of shaft and title
The middle position of heavy mail 5,1 top of shell is equipped with motor 2, and the output end of the motor 2 is equipped with shaft 3, the shaft 3
Across shell 1 and extend to the inside of shell 1, the outside of the shaft 3 is equipped with ring balance rotor 4, inside the shell 1
Side is equipped with weighing piece 5, and the shell 1 is equipped with weighing sensor 6 close to the side of weighing piece 5, and the shell 1 is far from weighing piece
5 side is equipped with DCS control system 7, and the weighing sensor 6 is electrically connected with DCS control system, leans on above the shell 1
The side of nearly DCS control system is equipped with feed inlet 8, and the inside of the feed inlet 8 is all equipped with equal scoreboard 9, the lower section of the shell 1
