The rotor weighing scale main body 1 is movably arranged on a main body support frame 4, and the frame is provided with a group of inclined load-bearing columns 5 on each of the left and right sides.

[0022] As shown in the embodiment, Figures 1-2 The motor device 2 and the feed inlet 3 are both stably installed at the top of the upper support structure 11. The main body support frame 4 is provided with a plurality of support foot 41 at the bottom, and is provided with a hydraulic buffer device 6 on the front and rear sides. The buffer device is connected with a connecting block 62 through a hydraulic lifting limiting rod 61, and finally supports and fixes the upper support structure 11. The top end of the inclined load-bearing column 5 is fixedly connected with a rotating assembly 51.

[0023] As shown in the embodiment of the present application, Figures 3-4 The rotating assembly 51 is provided with a movable rotating disc 14, which is fixedly connected to the lower sides of the upper support structure 11. The upper support structure 11 is provided with a load sensor 23 at the top. The motor device 2 is connected to the straight reduction gear 21 at one side and is provided with a speed sensor 22 at the other side.

[0024] Working principle

[0025] The inclined load-bearing column 5 of the novel powder material rotor weighing scale is connected in such a manner that the volume is reduced, the gravity center is lowered, and the scale body is more stable. The inflation device 8 is arranged to ensure that the material is completely discharged to prevent the material adhering to the rotor from affecting the measurement accuracy. The novel rotor weighing scale is provided with a lower support structure 12, the volume is reduced, the gravity center is lowered, and the scale body is more stable. There are many support cones and cone sleeves on the market, which are point connections but still friction structures. After being used for a period of time, the support cone and the cone sleeve become surface friction, which affects the accuracy of the scale. The bearing connection mode of the inclined load-bearing column 5 can avoid this situation. The weighing part adopts a downward pressing type, which is the most direct weight measurement method. When the material enters the rotor, the rotor rotates to move downward, and the load sensor 23 senses it. Through data analysis, the weight value is obtained, and the PLC control can meet the customer's measurement requirements. The novel rotor weighing scale is arranged above the main support frame 4, which is convenient for observation and maintenance. The material measured by the novel rotor weighing scale is discharged by gravity, but some materials have a large moisture content and are easy to adhere to the rotor. The inflation device 8 is arranged behind the discharge port 13. If such material is encountered, the inflation device 8 can be opened to ensure that the material is completely discharged to prevent the material adhering to the rotor from affecting the measurement accuracy.

[0026] Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.
