[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1 、 Figure 3 and Figure 4 The utility model provides an embodiment: a multi-pass sealing structure for the tail of a bucket elevator, including a base 1, the interior of the base 1 is fixedly connected to a shell 2, the base 1 supports and fixes the shell 2, the front end of the shell 2 is fixedly connected to a support plate 3, the shell 2 supports the support plate 3, the top of the support plate 3 is fixedly connected to a motor 4, the driving end of the motor 4 is fixedly connected to a feeding assembly, the support plate 3 supports the motor 4, which can improve the stability of the motor 4 and improve the working efficiency of the motor 4, the bottom inner wall of the shell 2 is fixedly connected to a fixing column 6, the shell 2 fixes the fixing column 6, the left side of the shell 2 is fixedly connected to a feed port 10, the feed port 10 is fixed to the shell 2 in an inclined manner, so that the material at the feed port 10 enters the interior of the shell 2, the outside of the feed port 10 is fixedly connected to a support shell 11, the feed port 10 can fix and support the support shell 11 to ensure that the internal structure of the support shell 11 can operate normally.

[0027] The feed port 10 is fixedly connected to a fixed plate 12 on the outside, and a motor 2 13 is fixedly connected to the left side of the fixed plate 12. The feed port 10 supports the fixed plate 12, and the fixed plate 12 fixes the motor 2 13, which can further improve the stability of the motor 2 13, reduce the noise generated when the motor 2 13 is working, reduce the vibration frequency of the motor 2 13, and improve the life of the motor 2 13. The driving end of the motor 2 13 is fixedly connected to a transmission column 14, and the external rotation of the transmission column 14 is connected to the inner wall of the support shell 11. The motor 2 13 drives the transmission column 14 to rotate. The support shell 11 can ensure that the transmission column 14 works stably. The external part of the transmission column 14 is fixedly connected to a water drop wheel 15. The external part of the water drop wheel 15 contacts the external part of the transmission wheel 16. The transmission column 14 rotates with the water drop wheel 15, so that the transmission wheel 16 and the water drop wheel 15 have a relative motion relationship under the rotation of the water drop wheel 15. The external rotation of the transmission wheel 16 is connected to a connecting piece 17, and the right side of the connecting piece 17 is fixedly connected to a moving rod 18, and the moving rod 18 is slidably connected to the inner wall of the feed port 10. When the protruding part of the water drop wheel 15 rotates to the inside, the transmission wheel 16 will be pushed inward. Under the action of the thrust, the connecting piece 17 is prompted to slide left and right with the moving rod 18 on the inner wall of the feed port 10. The external sleeve of the moving rod 18 is provided with a spring 19, one end of the spring 19 is fixedly connected to the right side of the connecting piece 17, and the other end of the spring 19 is fixedly connected to the outside of the feed port 10. The spring 19 can accelerate the working speed of the moving rod 18 and reduce the force buffering, thereby improving the stability of the overall structure. The right end of the moving rod 18 is fixedly connected to an anti-blocking plate 20. Under the action of the moving rod 18, the anti-blocking plate 20 dredges the feed port 10 to prevent blockage. The interior of the shell 2 is fixedly connected with a sealing component.

[0028] Reference Figure 2 The feeding assembly includes a driving wheel 5, a fixed column 6, and a driven wheel 7 that is externally rotatably connected. The driving wheel 5 and the driven wheel 7 are externally coupled with a belt 8. The outside of the belt 8 is fixedly connected to multiple feeding troughs 9. Under the action of the belt 8, the driving wheel 5 rotates and drives the driven wheel 7 to rotate, thereby realizing the transportation of materials.

[0029] Reference Figure 5 and Figure 6The sealing assembly includes a sealing ring 21. The inner wall of the sealing ring 21 is slidably connected to a rubber pad 22. The rubber pad 22 slides on the inner wall of the sealing ring 21, indicating that the friction between the two is small and the operation is smooth. The outer part of the fixed column 6 fits with the inner wall of the rubber pad 22. The rubber pad 22 can seal the fixed column 6 to prevent leakage. The outer part of the rubber pad 22 is fixedly connected to a telescopic column 23. The outer sleeve of the telescopic column 23 is provided with a spring 24. The telescopic column 23 can prevent the rubber pad 22 from deflecting when it is subjected to external force, thereby fixing the rubber pad 22. At the same time, it can prevent the spring 24 from being squeezed and deformed, which may cause the risk of the structure not being able to operate normally. The outside of the telescopic column 23 is fixedly connected to the limit block 25, and the outside of the limit block 25 is slidably connected to the inner wall of the sealing ring 21. The limit block 25 mainly limits the moving range of the rubber pad 22. One end of the spring 24 is fixedly connected to the left side of the limit block 25, and the other end of the spring 24 is fixedly connected to the inner wall of the sealing ring 21. The spring 24 uses its own rebound force to make the rubber pad 22 and the fixed column 6 fit more tightly, and the sealing effect is better.

[0030] Working principle: When pouring materials from the feed port 10, the feed port 10 is likely to be blocked. At this time, start the motor 2 13, and the transmission column 14 is driven to rotate by the motor 2 13. Then the transmission column 14 rotates with the water drop wheel 15 fixed on the outside. The rotation of the water drop wheel 15 causes the transmission wheel 16 to rotate on the inner wall of the connecting piece 17 and a relative motion relationship occurs between the water drop wheel 15 and the transmission wheel 16. When the cam part of the water drop wheel 15 collides with the transmission wheel 16, the water drop wheel 15 will give the transmission wheel 16 a rightward thrust, so that the transmission wheel 16 transmits the thrust to the connecting piece 17, so that the connecting piece 17 carries the moving rod 18 to make reciprocating motion on the inner wall of the feed port 10, thereby carrying the anti-blocking plate 20 to clear the feed port 10, preventing the feed port 10 from being blocked and affecting the material transportation efficiency. When the connecting piece 17 moves to the right, it will squeeze the spring 19. The spring 19 can improve the reciprocating motion efficiency while reducing the force buffer, thereby improving the structural stability.

[0031] When transporting materials, leakage is likely to occur at the tail of the machine. In order to avoid this, a sealing structure is provided at the tail, and the sealing ring 21 is sleeved on the outside of the fixed column 6. The fixed column 6 will exert force on the rubber pad 22 sliding on the inner wall of the sealing ring 21, thereby squeezing the spring 24. Under the action of the spring 24's own rebound force, the rubber pad 22 and the fixed column 6 fit more tightly, greatly improving the sealing effect. At the same time, the spring 24 is sleeved on the outside of the telescopic column 23. The telescopic column 23 can prevent the spring 24 from being deformed to a certain extent due to changes in its shape due to external force, thereby affecting the normal operation of the structure.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
