[0066] Example 1

[0067] Since it is difficult to change the width of the blades in the prior art, it is difficult to adapt to powder screening with different needs, and it is not convenient to adjust the angle of the blades.

The limiting seats 207 are arranged on the inner sides of the inner mounting plate 201 and the outer mounting plate 203, and are located at the lower side of the inner mounting bar 204. The inner end of the limiting seat 207 is rotatably connected with the positioning rod 206.

[0070] The compensation mechanism 202 includes a compensation block 20201, a first connecting block 20202, a second connecting block 20203 and a third connecting block 20204; the compensation block 20201 is installed on the inner side of the inner mounting plate 201, and the outer end of the compensation block 20201 is rotatably connected with the first connecting block 20202, the outer end of the first connecting block 20202 is rotatably connected with the second connecting block 20203, and the outer end of the second connecting block 20203 is connected with the third connecting block 20204, see Figure 2 ;

[0071] The inner side of the main air flow mechanism 2 is provided with an adjustment mechanism 4 installed on the outer side of the main rod 1. The adjustment mechanism 4 includes a mounting tube 401, a connecting ring 402, a long rod 403, a first adjustment rod 404, a connecting ring 405, a first connecting rod 406, a second connecting rod 407, a fixing seat 408 and a second adjustment rod 409; the mounting tube 401 is provided on the outer side of the main rod 1 and is located at the lower side of the stabilizing rod 3, and a connecting ring 402 is installed on the outer side of the mounting tube 401, and a first adjustment rod 404 is installed on the inner side of the connecting ring 402, and the outer end of the connecting ring 402 is rotated A long rod 403 is connected to the inner mounting plate 201 for rotation. A connecting ring 405 is installed at the lower end of the first adjusting rod 404 and is located outside the mounting tube 401. A first connecting rod 406 is installed at the outer end of the connecting ring 405. A second connecting rod 407 is rotatably connected to the outer side of the first connecting rod 406. A fixing seat 408 fixed to the outer side of the main rod 1 is provided at the inner end of the second connecting rod 407, and a second adjusting rod 409 is installed on the inner side of the fixing seat 408. For details, see Figure 8 .

[0072] When using the wind guide rectifier blades in the embodiment of the present invention, specifically as follows Figure 1 In the process, the upper end of the main rod 1 is first connected to the active shaft of the powder classifier to drive the device as a whole to rotate, and then Figure 2 , Figure 7 and Figure 8 As shown, the second adjusting rod 409 is rotated, and the threaded connection between the second adjusting rod 409 and the fixing seat 408 and the sliding connection between the mounting tube 401 and the main rod 1 are utilized to make the mounting tube 401 slide on the outside of the main rod 1, and the rotation connection between the first connecting rod 406 and the second connecting rod 407 makes it possible to change the angle between the second connecting rod 407 and the first connecting rod 406, so that the inclination angle of the inner mounting plate 201 is changed, and at the same time, the first adjusting rod 404 can be rotated, and the first adjusting rod 40 The threaded connection between the connecting ring 402 and the connecting ring 402 and the sliding connection between the connecting ring 402 and the mounting tube 401 can make the connecting ring 402 slide on the outside of the mounting tube 401, so that the inclination angle of the long rod 403 is changed, so that the inclination angle of the inner mounting plate 201 can be further increased. At the same time, when the inclination angle of the inner mounting plate 201 changes, the upper end of the stabilizing rod 3 will slide on the outside of the main rod 1 to adapt to the change of the inclination angle of the inner mounting plate 201, and the stabilizing rod 3 is used to increase the installation stability of the upper end of the inner mounting plate 201.

[0073] Specific as Figure 2When the inner mounting plate 201 changes its inclination angle, the outer end of the compensation block 20201 is rotated with the first connecting block 20202 and the outer end of the first connecting block 20202 is rotated and connected with the second connecting block 20203, and the outer end of the second connecting block 20203 is connected with the third connecting block 20204, so that the gap between the monomers of the inner mounting plate 201 can be compensated, so that the inner mounting plate 201 still maintains a complete ring shape. When it is necessary to increase the overall width of the main airflow mechanism 2, specifically as follows Figure 6 and Figure 7 The bolts on the upper end of the outer mounting plate 203 are loosened so that the upper end of the outer mounting plate 203 and the inner mounting plate 201 can be disassembled, and then the outer mounting plate 203 is rotated outward. During the rotation process, the positioning rod 206 slides inside the inner mounting plate 201 and the outer mounting plate 203, so that the outer mounting plate 203 has a certain limit during the flipping process, and then the lower end of the outer mounting plate 203 is bolted to the raised structure set at the lower end of the inner mounting plate 201, thereby changing the overall width of the main air flow mechanism 2, and a groove-like structure is opened at equal angles on the inner side of the inner mounting plate 201, and a threaded hole-like structure is opened on the inner side of the groove-like structure and the outer side of the inner mounting strip 204, so that the inner mounting plate 201 and the outer side of the inner mounting strip 204 after flipping can be extended to install outer mounting strips 205 of different sizes for wind guide and rectification.

[0074] Example 2

[0075] Based on Example 1, the difference between the embodiment of the present invention and Example 1 is that the wind-guiding straightening blade with variable width also includes a mounting seat 6; the mounting seat 6 is mounted on the lower end of the main rod 1, and a lower air guide mechanism 5 is mounted on the outer side of the mounting seat 6, the lower air guide mechanism 5 includes a connecting plate 501, a compensation plate 502, a fixing strip 503 and a compensation wing 504, a fixing strip 503 is mounted on the outer side of the connecting plate 501, and a compensation plate 502 is mounted on the inner side of the connecting plate 501, and a compensation wing 504 is mounted on the upper side of the outer end of the compensation plate 502, a mounting column 7 is mounted on the lower end of the mounting seat 6, and an adjusting ring 9 is mounted on the outer side of the mounting column 7, a connecting seat 10 is mounted on the outer side of the adjusting ring 9, and a limiting rod 8 is arranged on the inner side of the connecting seat 10, a positioning seat 11 is arranged on the inner side of the lower air guide mechanism 5, and an auxiliary rod 12 is installed on the inner end of the positioning seat 11, see specifically Figure 3-5 .

[0076] like Figure 1 , Figure 3 and Fig.10In the embodiment, by rotating the adjusting ring 9, the threaded connection between the mounting column 7 and the adjusting ring 9 is utilized to make the adjusting ring 9 move up and down outside the mounting column 7, and the threaded connection between the connecting seat 10 and the adjusting ring 9 is utilized to prevent the connecting seat 10 from rotating with the adjusting ring 9. The up and down movement of the adjusting ring 9 can drive the limiting rod 8 to change the inclination angle, thereby changing the inclination angle of the lower end of the lower guide mechanism 5. Fig. 9 In the embodiment, when the inclination angle of the lower guide mechanism 5 changes, the positioning seat 11 will slide in the connecting plate 501 to adapt to the change in inclination angle and increase the installation stability of the connecting plate 501;

[0077] At the same time Figure 3 , Figure 4 and Figure 5 In the figure, when the inclination angle of the connecting plate 501 changes, the compensation wings 504 are symmetrically arranged about the center of the compensation plate 502, the upper ends of the compensation wings 504 are arc-shaped, the compensation plate 502 and the connecting plate 501 are rotatably connected, and a groove structure for loading the compensation plate 502 and the compensation wings 504 is provided on the inner side of the connecting plate 501. This allows the connecting plate 501 to maintain a complete ring shape after the angle is adjusted, thereby avoiding affecting the wind direction.
