[0002] After the cut tobacco of cigarettes is shredded in the cut tobacco workshop, in order to improve the quality of the cut tobacco, it needs to be stored in a storage cabinet for 24 hours for appropriate aging. Since the cut tobacco in the storage cabinet usually reaches nearly one meter thick, when the cut tobacco is aging in the storage cabinet, under the action of gravity, the cut tobacco will sink and become solid. Therefore, a multi-layer rake wire device is arranged at the discharging end to loosen the cut tobacco, so that the cut tobacco can flow smoothly onto the lower feeding belt in a loose state.

[0003] However, the existing rake wire mechanism usually uses a rake wire roller with a mace structure to turn the cut tobacco upwards reversely. The rake wire effect is good, but the running resistance is very large and the cut tobacco is severely broken. In recent years, a manipulator-type flexible discharging device for directional rake wire, such as the manipulator-type flexible discharging device for a storage cabinet disclosed in CN201610889535.8, has emerged. Although the breakage rate of the cut tobacco can be reduced by this technology, components such as the driven disk, the dial rod and the connecting rod are worn more during long-term movement, so they need to be disassembled, maintained or replaced frequently. And the installation and disassembly of components such as the dial rod and the connecting rod require the disassembly of the driven disk or the driving disk and then the maintenance and replacement of the dial rod and the connecting rod, which brings great inconvenience to tobacco production.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1 , an embodiment of the present invention provides a variable-angle directional flexible rake nail device for a cut tobacco cabinet, including: two end covers 1, a passive disc 11 and a bent plate 10 that are symmetrically arranged on the left and right.

[0025] Among them, as Figure 1 and Figure 2 shown, a plurality of flange bearing seats 4 are symmetrically installed on the adjacent surfaces of the two end covers 1. A rake nail shaft 2 is installed inside every two flange bearing seats 4 on the same horizontal axis through bearings. L-shaped rake nails 3 are evenly arranged side by side on the rake nail shaft 2. A self-aligning bearing seat 9 is installed on the bent plate 10. One side of the passive disc 11 is installed on the self-aligning bearing seat 9 through a bearing. A core shaft 7 is fixedly connected to the center of the end cover 1. A speed reducer 6 is provided at one end of the core shaft 7, and one end of the core shaft 7 is fixed to the rotating shaft of the speed reducer 6.

[0026] During use, the rake nail shaft 2 is supported by the flange bearing seats 4 in the two end covers 1. The L-shaped rake nails 3 are evenly distributed on the rake nail shaft 2. By starting the speed reducer 6, the core shaft 7 can be driven to drive the end cover 1 and the rake nail shaft 2 to rotate, and the rake nails 3 can rake the cut tobacco.

[0027] Furthermore, a bracket 5 is installed at the bottom of the speed reducer 6, and the bracket 5 can conveniently fix and install the speed reducer 6 in the motor working area.

[0028] In this embodiment, as Figure 1 ,Figure 3 and Figure 5 As shown, a plurality of bushings 13 are symmetrically installed on the other side of the driven disk 11. One end of the bushing 13 is installed with a connecting rod 8 through a pin shaft 12. One end of the harrow nail shaft 2 close to the driven disk 11 is provided with a cylinder body 16. One end of the cylinder body 16 is slidably installed with a spline shaft 17. And a spring 18 is arranged inside the cylinder body 16. One end of the spring 18 abuts against one inner wall of the cylinder body 16, and the other end abuts against one end of the spline shaft 17. A spline hole 15 is provided at the end of the connecting rod 8 away from the bushing 13. The spline shaft 17 is inserted into the spline hole 15. When the harrow nail shaft 2 rotates, one end of the harrow nail shaft 2 can drive the driven disk 11 to rotate through the connecting rod 8. And because the harrow nail shaft 2 can be continuously pulled by the connecting rod 8, the harrow nails 3 on the harrow nail shaft 2 can adjust the orientation of the harrow nails 3 according to the different positions of the spline shaft 17 inserted in the spline hole 15, and insert into the cut tobacco and rake the cut tobacco.

[0029] When the harrow nail shaft 2 or the connecting rod 8 is replaced and disassembled, the spline shaft 17 can be pressed through the opening at one end of the spline hole 15 to make it slide in the cylinder body 16 until the spline shaft 17 disengages from the spline hole 15, so that the end of the harrow nail shaft 2 can be disconnected from the connecting rod 8. When the end of the harrow nail shaft 2 is connected to the connecting rod 8 through the spline shaft 17, only need to align the pressed spline shaft 17 with the spline hole 15 and release the pressing state, and use the spring 18 to push the spline shaft 17 to slide and insert into the spline hole 15 to complete the connection between the end of the harrow nail shaft 2 and the connecting rod 8.

[0030] Further, referring to Figure 5 , in order to facilitate the spline shaft 17 to be fitted and connected with the spline hole 15 at one end of the connecting rod 8, the outer wall of one end of the spline shaft 17 close to the spline hole 15 is provided with an external spline matching the shape of the spline in the spline hole 15. In addition, the outer diameter of one end of the spline shaft 17 located in the cylinder body 16 is larger than the inner diameter of the opening of the cylinder body 16, which can prevent one end of the spline shaft 17 from directly disengaging outward in the cylinder body 16.

[0031] As Figure 4 shown, the bent plate 10 is an L-shaped plate structure, and two kidney-shaped grooves 14 are symmetrically provided on the outer wall of the horizontal plane of the bent plate 10. The bottom of the horizontal plane of the bent plate 10 can be attached to the harrow wire workbench surface, and the bent plate 10 is fixed therein by a fixing member passing through the kidney-shaped grooves 14.

[0032] Summarize and sort out the working steps of this solution according to the above technical solution: When the utility model is used, the harrow nail shaft 2 is supported by the flange bearing seats 4 in the two end covers 1. The L-shaped harrow nails 3 are evenly distributed on the harrow nail shaft 2. By starting the reducer 6, the core shaft 7 can be driven to drive the end cover 1 to rotate, and the harrow nails 3 can rake the cut tobacco.

[0033] Among them, one end of the rake nail shaft 2 can drive the driven disk 11 to rotate through the connecting rod 8. Since the rake nail shaft 2 can be continuously pulled by the connecting rod 8, the rake nails 3 on the rake nail shaft 2 can adjust the orientation of the rake nails 3 according to the different positions of the spline shaft 17 inserted into the spline hole 15, and insert into and rake the cut tobacco.

[0034] In addition, when the rake nail shaft 2 or the connecting rod 8 is replaced or disassembled, the spline shaft 17 can be pressed through the opening at one end of the spline hole 15 to make it slide in the cylinder body 16 until the spline shaft 17 disengages from the spline hole 15, so that the connection state between the end of the rake nail shaft 2 and the connecting rod 8 can be cancelled, which is convenient for the replacement and disassembly of the rake nail shaft 2 or the connecting rod 8. When the end of the rake nail shaft 2 is connected to the connecting rod 8 through the spline shaft 17, only need to align the spline shaft 17 in the pressed state with the spline hole 15 and release the pressed state, and use the spring 18 to push the spline shaft 17 to slide and insert into the spline hole 15 to complete the connection between the end of the rake nail shaft 2 and the connecting rod 8, improving the installation efficiency and the replacement and disassembly efficiency of the rake nail shaft 2 and the connecting rod 8.

[0035] Parts not involved in the present utility model are the same as or can be implemented by the prior art. Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
