Description

Technical Field

[0001] The utility model relates to the technical field of asphalt pavement construction equipment, in particular to a lignin fiber feeding mechanism. Background Art

[0002] Lignin fiber is an organic fiber obtained by chemical treatment of natural wood. It has a cotton-like appearance and is white or grayish white. It is mainly used in road paving and is an indispensable stabilizer.

[0003] Lignin fibers need to be screened, split, treated at high temperatures, bleached, chemically treated, neutralized, and screened into fibers of different lengths and coarsenesses to meet the needs of different application materials. A screening device is needed in the screening process. However, lignin fibers tend to clump together when entering the screening device, causing the screen to be blocked. They also need to be screened separately from the feeding mechanism, and cannot be screened during the lignin fiber feeding process, resulting in low efficiency. Utility Model Content

[0019] The utility model embodiment provides a lignin fiber feeding mechanism, such as Figure 1-3 As shown, it includes a tube body 11, a workbench 15, an output shaft 17, a revolution box 18, a dredging assembly and a screen 24. The tube body 11 is connected between the feed pipes through flanges on both sides. A feeding channel 12 is opened in the tube body 11. The lignin fiber is transported from the upper side of the feeding channel 12 to the lower side of the feeding channel 12. Figure 2As shown, a revolving groove 13 connected with the feeding channel 12 is provided in the tube body 11, and a mounting groove 14 is provided at the lower side of the revolving groove 13. A workbench 15 is fixedly provided on the side wall of the feeding channel 12, and a power motor 16 is fixedly provided on the lower end face of the workbench 15. The power motor 16 has the same structure as that of the prior art. The power of the output shaft 17 comes from the power motor 16. A revolving box 18 is fixedly provided at the lower end of the output shaft 17. A rotation groove 19 is provided in the revolving box 18. The dredging component is provided in the rotation groove 19. The dredging component moves synchronously with the revolving box 18. A screen 24 is placed in the mounting groove 14, and the screen 24 is used to screen out large-particle lignin fibers.

[0020] The height of the revolution groove 13 is higher than that of the revolution box 18 , and a gear ring 23 is fixedly disposed in the revolution groove 13 , thereby facilitating the installation of the revolution box 18 and the gear ring 23 .

[0021] like Figure 3 As shown, the dredging component includes a rotating shaft 20, a bevel gear 21 and a brush 22. One end of the rotating shaft 20 is rotatably connected to the inner wall of the rotating groove 19, and the other end of the rotating shaft 20 passes through the side of the revolution box 18 away from the output shaft 17. The bevel gear 21 is fixed to the end of the rotating shaft 20 away from the output shaft 17. The brush 22 is arranged in a ring array on the outer cylindrical surface of the rotating shaft 20, and the bevel gear 21 is meshed with the ring gear 23.

[0022] When the power motor 16 drives the output shaft 17 to rotate, the output shaft 17 drives the revolution box 18 on the lower side to revolve, and the revolution box 18 drives the brush 22 to revolve synchronously through the rotation shaft 20. During the revolution of the rotation shaft 20, the bevel gear 21 is engaged with the ring gear 23, so that when the revolution box 18 drives the rotation shaft 20 to revolve, the bevel gear 21 causes the rotation shaft 20 to rotate, and the rotation shaft 20 drives the brush 22 on the outer cylindrical surface to rotate, so that the brush 22 cleans the large particles of lignin fibers screened out on the screen 24, thereby breaking them up, preventing the screen 24 from being blocked when the lignin fibers are added, thereby affecting the feeding efficiency.

[0023] In another embodiment, the contact surface between the bevel gear 21 and the ring gear 23 is a conical surface, and both the bevel gear 21 and the ring gear 23 are made of rubber. The ring gear 23 uses the friction force of the conical surface to make the bevel gear 21 drive the rotating shaft 20 to rotate during the process of the revolution box 18 driving the rotating shaft 20 to revolve.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
