[0019] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] Embodiments of the present invention: such as Figures 1-4 As shown, a device for dispersing clumps of stems includes a hopper 1, a transmission box 2 fixedly installed at the bottom of the hopper 1, a discharge pipe 3 connected to the bottom of the hopper 1, a lower stirring assembly and an upper stirring assembly rotatably installed inside the hopper 1, and a transmission assembly inside the transmission box 2, which is used to drive the lower stirring assembly and the upper stirring assembly to rotate in opposite directions.

[0021] The hopper 1 is a cylindrical hopper body used to hold clumps of stems. To prevent the stems from falling out of the top of the hopper 1, a conical hopper top 4 is provided at the top of the hopper 1. A feed inlet 5 is provided at the top of the hopper top 4, and a baffle ring 6 is fixed on the feed inlet 5.

[0022] By rotating the lower and upper mixing components in opposite directions, the clumps of strands can be loosened more efficiently and with higher quality.

[0023] Specifically, the lower mixing assembly includes a hollow rotating shaft 7, an upper bearing seat 8, and first rake nails 9. The upper bearing seat 8 is fixedly installed on the top plate inside the transmission box 2 by bolts. The upper bearing seat 8 is coaxially arranged with the hopper 1. The hollow rotating shaft 7 passes through the bottom plate of the hopper 1, the top plate of the transmission box 2, and the upper bearing seat 8. The hollow rotating shaft 7 is rotatably connected to the upper bearing seat 8. Several first rake nails 9 are provided on the outer wall of the hollow rotating shaft 7.

[0024] The outer wall of the hollow shaft 7 is interference-fitted with the inner ring of the upper bearing housing 8. The upper bearing housing 8 ensures that the hollow shaft 7 remains vertical and can rotate smoothly.

[0025] The first rake nail 9 is set in multiple groups, with each group of first rake nail 9 located at the same height. Each group of first rake nail 9 consists of three nails, which are evenly distributed along the circumference of the hollow rotating shaft 7. Adjacent groups of first rake nail 9 are staggered.

[0026] In this embodiment, two sets of first rake spikes 9 are preferably provided, both of which are arranged horizontally. Of course, more sets of first rake spikes 9 can be provided according to actual needs. The first rake spikes 9 are used to stir the filaments located in the lower part of the hopper 1.

[0027] Furthermore, a first limiting boss 10 and a second limiting boss 11 are formed on the outer wall of the hollow rotating shaft 7. The second limiting boss 11 is located below the first limiting boss 10. The outer diameter of the first limiting boss 10 is larger than the inner diameter of the upper bearing seat 8. The top surface of the first limiting boss 10 abuts against the lower end of the bearing inner ring of the upper bearing seat 8.

[0028] The first limiting boss 10 prevents the hollow shaft 7 from moving upwards after prolonged operation. If the hollow shaft 7 moves upwards, it will disengage from the transmission assembly, causing the hollow shaft 7 to be unable to rotate. The first limiting boss 10 serves as an axial limiting element.

[0029] Furthermore, the upper stirring assembly includes a solid rotating shaft 12, a lower bearing seat 13, and second rake nails 14. The length of the solid rotating shaft 12 is greater than the length of the hollow rotating shaft 7. The solid rotating shaft 12 passes through the hollow rotating shaft 7 and can rotate inside the hollow rotating shaft 7. The lower bearing seat 13 is fixed to the bottom plate outside the transmission box 2 by a bolt assembly. The lower bearing seat 13 and the upper bearing seat 8 are arranged coaxially. The lower end of the solid rotating shaft 12 passes through the bottom plate of the transmission box 2 and is installed in the lower bearing seat 8. Several second rake nails 14 are provided on the outer wall of the part of the solid rotating shaft 12 that is higher than the hollow rotating shaft 7.

[0030] The lower end of the solid rotating shaft 12 is interference-fitted with the inner ring of the bearing in the lower bearing housing 8. In order to ensure that the solid rotating shaft 12 can rotate smoothly in the hollow rotating shaft 7 and reduce friction, ball bearings (not shown in the figure) can be installed at both ends inside the hollow rotating shaft 7. The ball bearings can improve the rotational smoothness of the solid rotating shaft 12.

[0031] Furthermore, the transmission assembly includes a driving bevel gear 15, a first driven bevel gear 16, and a second driven bevel gear 17. The first driven bevel gear 16 is fixedly mounted on the lower end of the hollow rotating shaft 7, and the upper end of the first driven bevel gear 16 abuts against the second limiting boss 11. The second driven bevel gear 17 is fixedly mounted on the solid rotating shaft 12 and is located below the first driven bevel gear 16. The driving bevel gear 15 is located between the second driven bevel gear 17 and the first driven bevel gear 16, and the driving bevel gear 15 meshes with both the first driven bevel gear 16 and the second driven bevel gear 17.

[0032] The active bevel gear 15 is fixedly mounted on one end of the drive shaft 18, and the other end of the drive shaft 18 passes through the side wall of the transmission box 2 and is fixedly connected to the pulley 19. The pulley 19 is connected to the pulley on the drive motor via a toothed belt. The drive motor and the toothed belt are prior art and are not shown in the figure.

[0033] The working principle of this invention is as follows: During operation, the clumps of stems are fed into the hopper 1 through the feed inlet 5. The baffle ring 6 is used to block the stems and prevent them from falling off. The drive motor is started, and the drive motor drives the pulley 19 to rotate through the toothed belt. The pulley 19 drives the active bevel gear 15 to rotate through the drive shaft 18. When the active bevel gear 15 rotates, it simultaneously drives the first driven bevel gear 16 and the second driven bevel gear 17 to rotate. Since the rotation directions of the first driven bevel gear 16 and the second driven bevel gear 17 are opposite, the rotation directions of the hollow rotating shaft 7 and the solid rotating shaft 12 are opposite, which makes the rotation directions of the first rake nail 9 and the second rake nail 14 opposite. The clumps of stems can be quickly broken up by the first rake nail 9 and the second rake nail 14.

[0034] The above description, based on the embodiments shown in the figures, details the structure, features, and effects of the present invention. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, that do not exceed the spirit covered by the specification and figures, should be within the protection scope of the present invention.
