Specifically, in the above embodiment, the materials of the conveying screw 220 and the charging barrel 210 are TA2, and the above screw feeding device is used for horizontally conveying the high-nickel ternary material, and the TA2 does not generate magnetic foreign matters in the conveying process of the high-nickel ternary material, so that the yield of the high-nickel ternary material is not affected even if the conveying screw 220 or the charging barrel 210 rubs to make the TA2 fall off in the charging barrel 210.

More specifically, referring to fig. 2, in the above embodiment, a feeding port 214 and a discharging port 215 are formed on the wall of the charging barrel 210, the feeding port 214 is formed near the first end 211, and the discharging port 215 is formed near the second end 212. The first connection assembly 300 further includes a first sealing member 360, a connection between the first connection member 310 and the third connection member 330, and a connection between the first connection member 310 and the first bearing portion 353 are provided with the first sealing member 360, the second connection assembly 400 further includes a second sealing member 430, and a connection between the seventh connection member 420 and the sixth connection member 410, a connection between the sixth connection member 410 and the driving end 221, and a connection between the second bearing portion 423 and the sixth connection member 410 are provided with the second sealing member 430.

It will be appreciated that the material inlet 214 enters the charging barrel 210 and is conveyed to the next device or pipeline at the outlet 215, and in this process, when the material enters the charging barrel 210 from the inlet 214, the air is blown from the driving end 221 to the inside of the charging barrel 210, so that the material does not enter the second connecting assembly 400 and the driving assembly 100 from the driving end 221, thereby avoiding the material from blocking the second connecting assembly 400 and the driving assembly 100, and prolonging the service life of the second connecting assembly 400 and the driving assembly 100. Similarly, when the material is discharged from the discharge hole 215 to the charging barrel 210, the air is blown into the charging barrel 210 from the driven end 222, so that the material can not enter the first connecting assembly 300 from the driven end 222, and the first connecting assembly 300 is prevented from being blocked by the material, so that the service life of the first connecting assembly 300 is prolonged.

Specifically, in the above-described embodiment, referring to fig. 1, the driving assembly 100 includes the driving motor 120 and the decelerator 130, the driving end of the driving motor 120 is connected to the decelerator 130, the driving shaft 110 is disposed on the decelerator 130, and the driving shaft 110 is connected to the sixth connection member 410.

Any particular values in all examples shown and described herein are to be construed as merely illustrative and not a limitation, and thus other examples of exemplary embodiments may have different values.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.

The above examples merely represent a few embodiments of the present utility model, which are described in more detail and are not to be construed as limiting the scope of the present utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
