[0011] Furthermore, a third scraper plate corresponding to the grinding wheel is connected to the rotating block.

[0012] Furthermore, two grinding wheels are symmetrically arranged.

[0013] Beneficial effects: Compared with the prior art, the utility model has the following advantages:

The spiral conveying component 1 includes a conveying shell 11, a spiral blade 12 and a conveying motor 13. The conveying shell 11 is cylindrical. The spiral blade 12 is arranged on the transmission shaft in the conveying shell 11. The conveying motor 13 is arranged at one end of the conveying shell 11. The conveying motor 13 is connected to the transmission shaft through a conveying reducer to drive the spiral blade 12 to rotate. A first feed port 101 and a first discharge port 102 are provided on the conveying shell 11. The first feed port 101 is arranged at the upper part of one end of the conveying shell 11. A receiving hopper is connected to the first feed port 101. The receiving hopper is used to receive the yellow iron oxide in the packaging bag. The first discharge port 102 is arranged at the lower part of one end of the conveying shell 11. The yellow iron oxide conveyed by the spiral blade 12 is discharged from the first discharge port 102. The control box 3 is provided with a first frequency converter 31 and a second frequency converter 32 . The first frequency converter 31 is electrically connected to the conveying motor 13 , so that the control box 3 can control the operating speed of the conveying motor 13 and the conveying speed of the spiral blade 12 .

[0026] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the grinding wheel assembly 2 includes a bracket 21, a working cylinder 22, a grinding wheel 23 and a driving assembly. The working cylinder 22 is a cylindrical shell with an upper opening. The first discharge port 102 is connected to the side wall of the working cylinder 22 through a slide tube 4. The iron oxide yellow discharged from the first discharge port 102 slides into the working cylinder 22 through the slide tube 4. The bracket 21 includes a plurality of supporting legs connected to the bottom of the working cylinder 22. There are two grinding wheels 23 symmetrically arranged in the working cylinder 22. The driving assembly includes a first intermediate shaft 24, a rotating block 25, a second intermediate shaft 26, a reducer 27 and a second motor 28. The second motor 28 and the reducer 27 are located below the working cylinder 22 and are connected to the bracket 21. The reducer 27 is connected to the second motor 28 and the reducer 27 through a belt. The reducer 27 is connected to the second intermediate shaft 26 and drives the second intermediate shaft 26 to rotate. The second intermediate shaft 26 passes through the center position of the bottom wall of the working cylinder 22 and extends upward into the working cylinder 22. The rotating block 25 is connected to the second intermediate shaft 26. The rotating block 25 is connected to the grinding wheel 23 through the first intermediate shaft 24. When the second intermediate shaft 26 rotates, it drives the rotating block 25 to rotate, thereby driving the grinding wheel 23 to rotate. The rotating block 25 is also connected to the bearing frame, and a bearing is provided in the bearing frame. The grinding wheel 23 is connected to the bearing of the bearing frame through the third intermediate shaft, so that when the grinding wheel 23 rotates around the second intermediate shaft 26, the grinding wheel 23 can rotate by itself. When the grinding wheel 23 rotates around the second intermediate shaft 26 and rotates by itself, the annular outer wall of the grinding wheel 23 grinds the iron oxide yellow on the bottom wall of the working cylinder 22. The second frequency converter 32 is electrically connected to the second motor 28, so that the rotation speed of the roller 23 can be controlled by the control box 3. A cylinder cover (not shown) is also provided above the working cylinder 22 to prevent dust from flying.

[0027] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the rotating block 25 is connected to a first scraper plate 51 and a second scraper plate 52. The first scraper plate 51 is arranged in the working cylinder 22 near the inner wall of the working cylinder 22. The bottom of the first scraper plate 51 is close to the inner bottom wall of the working cylinder 22. When the rotating block 25 drives the first scraper plate 51 to rotate, the first scraper plate 51 scrapes the yellow iron oxide powder on the inner bottom wall of the working cylinder 22. The second scraper plate 52 is arranged in the working cylinder 22 near the center position and extends outward along the center position. The second scraper plate 52 is arranged obliquely. When the rotating block 25 drives the second scraper plate 52 to rotate, the second scraper plate 52 scrapes the yellow iron oxide powder near the center position on the inner bottom wall of the working cylinder 22 and pushes it outward. Two discharge holes 221 are provided on the bottom wall of the working cylinder 22. The discharge holes 221 are circular. The trajectory of the grinding wheel 23 walking on the bottom wall of the working cylinder 22 forms an annular grinding surface ( Figure 5The discharge hole 221 is located outside the annular rolling surface, so that the roller 23 does not pass through the discharge hole 221, and the area where the first scraper 51 moves under the drive of the rotating block 25 forms an annular scraping surface 511 ( Figure 6 The projection of the annular scraping surface 511 on the bottom wall of the working cylinder 22 overlaps with the discharge hole 221, so that when the first scraper plate 51 rotates, the iron oxide yellow powder on the inner bottom wall of the working cylinder 22 can be scraped to the discharge hole 221. The iron oxide yellow powder is discharged from the discharge hole 221 and slides down the discharge slide 222 to enter the next link. The second scraper plate 52 pushes the iron oxide yellow powder at the center of the working cylinder 22 in the outward circumferential direction onto the annular rolling surface. The grinding wheel 23 grinds the iron oxide yellow powder. The rolled iron oxide yellow powder enters the discharge hole 221 under the action of the first scraper plate 51. The rotating block 25 is also connected to a third scraper plate 29 corresponding to the grinding wheel 23. The third scraper plate 29 is arranged horizontally above the grinding wheel 23, and the lower side of the third scraper plate 29 is in contact with the surface of the grinding wheel 23, thereby scraping off the powder adhering to the surface of the grinding wheel 23.

[0028] By controlling the conveying speed of the spiral conveying assembly 1 through the control box, the feeding speed in the working cylinder 22 can be controlled, and controlling the rotation speed of the driving assembly of the grinding wheel assembly 2 can reduce the rotation speed of the grinding wheel 23, thereby realizing feeding and discharging of the working cylinder 22 at the same time, changing the traditional unified feeding and unified discharging mode.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
