[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1-9A reverse pulse jet cleaning mechanism for a mobile screening machine includes a U-shaped support frame 1, a transverse screening cylinder 3 is provided on the top of the U-shaped support frame 1, a discharge port 2 is provided at one end of the transverse screening cylinder 3, and a cleaning mechanism for cleaning the transverse screening cylinder 3 is provided on one side of the bottom of the U-shaped support frame 1.

[0027] The transverse screening cylinder 3 consists of two circular rotating rings 31, multiple transverse connecting screening rods 32, and a transverse rotating column 33. Multiple transverse connecting screening rods 32 are evenly distributed and fixed between the two circular rotating rings 31. One end of one of the transverse connecting screening rods 32 is rotatably connected to the discharge port 2 via a bearing. The transverse rotating column 33 is fixed inside the circular rotating ring 31. The first drive motor 4 is fixed inside the U-shaped support frame 1 with bolts. Circular pulleys 9 are fixed to the output end of the first drive motor 4 and the outer side of one end of the transverse rotating column 33. The two circular pulleys 9 are connected by a track. Through the operation of the first drive motor 4, one of the circular pulleys 9 can rotate. Through the track, the other circular pulley 9 can rotate, thereby enabling the transverse rotating column 33 and the circular rotating ring 31 to rotate, which in turn enables the transverse connecting screening rods 32 to rotate, allowing the material inside the transverse connecting screening rods 32 to be screened.

[0028] The cleaning mechanism includes a transverse sliding box 8, with an airflow box 10 fixed at one end of the top of the transverse sliding box 8. A connecting air pipe 11 is fixed inside the transverse sliding box 8 and connected to the airflow box 10. A reciprocating polishing and cleaning belt 14 is provided on the top of the transverse sliding box 8. A motion mechanism for the reciprocating motion of the polishing and cleaning belt 14 is provided inside the transverse sliding box 8. The airflow box 10 can spray cleaning liquid or spray high-pressure airflow through an external pump or an external pump connected to the connecting air pipe 11, so that the airflow box 10 can clean the dust on the outside of the transverse connecting screening rod 32.

[0029] A second drive motor 5 is bolted to one end of the U-shaped support frame 1. A transverse threaded rod 6 is fixed to the output end of the second drive motor 5. The transverse threaded rod 6 passes through the interior of the transverse sliding box 8 and is threadedly connected to the transverse sliding box 8. A transverse smooth rod 7 is provided at the top and bottom of the transverse threaded rod 6. The transverse smooth rod 7 is close to one end of the U-shaped support frame 1 and is fixedly connected to the U-shaped support frame 1. The transverse smooth rod 7 passes through the interior of the transverse sliding box 8 and is slidably connected to the transverse sliding box 8, so that the transverse sliding box 8 can move laterally outside the transverse smooth rod 7, thereby allowing the transverse sliding box 8 and the airflow box 10 to be adjusted laterally.

[0030] Here, the operation of the second drive motor 5 enables the transverse threaded rod 6 to rotate, and the rotation of the transverse threaded rod 6 enables the transverse sliding box 8 to move laterally outside the transverse smooth rod 7. The movement of the transverse sliding box 8 enables the transverse position of the airflow box 10 to be adjusted. Through an external pump or an external pump connected to the connecting air pipe 11, the airflow box 10 can spray cleaning liquid or spray high-pressure airflow, so that the airflow box 10 can clean the dust on the outside of the transverse connecting screening rod 32.

[0031] The motion mechanism includes a U-shaped mounting base 12. The bottom of the transverse sliding box 8 is fixed with a U-shaped mounting base 12. One end of the U-shaped mounting base 12 is bolted to a third drive motor 13. The output end of the third drive motor 13 is fixed with a rectangular rotating column 18. One end of the rectangular rotating column 18 is rotatably connected to a rectangular transmission column 19 via a pin. One end of the rectangular transmission column 19 is rotatably connected to an L-shaped sliding column 20 via a pin. The L-shaped sliding column 20 is located outside the transverse sliding box 8 and is slidably connected to the transverse sliding box 8. One end of the L-shaped sliding column 20 is fixed with a rectangular connecting block 21.

[0032] The rectangular connecting block 21 has a rectangular groove inside that fits the polishing and cleaning belt 14. The polishing and cleaning belt 14 has a circular through hole inside. The rectangular connecting block 21 and the polishing and cleaning belt 14 are connected by hexagonal bolts. The hexagonal bolts are threaded to the rectangular connecting block 21. The hexagonal bolts are located inside the circular through hole and are movably connected to the polishing and cleaning belt 14 through the circular through hole, so that one end of the polishing and cleaning belt 14 can be inserted into the rectangular connecting block 21. By setting the hexagonal bolts, the movement of the polishing and cleaning belt 14 inside the rectangular connecting block 21 can be restricted, so that the polishing and cleaning belt 14 can be fixed inside the rectangular connecting block 21.

[0033] One end of the top of the transverse sliding box 8 is rotatably connected to the transverse support roller 15 via a bearing. The transverse support roller 15 is located on the bottom outer side of the grinding and cleaning belt 14, so that the grinding and cleaning belt 14 can be located on the top outer side of the transverse support roller 15. When the grinding and cleaning belt 14 moves, the transverse support roller 15 can rotate.

[0034] The interior of the transverse sliding box 8 is provided with a rectangular sliding groove. The other end of the polishing and cleaning belt 14 is fixed with a rectangular slider 16. The rectangular slider 16 is located inside the rectangular sliding groove and is slidably connected to the transverse sliding box 8 through the rectangular sliding groove. A longitudinal rigid spring 17 is provided at the end of the rectangular slider 16 away from the polishing and cleaning belt 14, and the longitudinal rigid spring 17 is located inside the rectangular sliding groove. The rectangular sliding groove allows the rectangular slider 16 to slide inside the transverse sliding box 8, and the movement of the rectangular slider 16 causes the longitudinal rigid spring 17 to deform under force.

[0035] Here, one end of the grinding and cleaning belt 14 is wrapped around the outside of the transverse connecting screening rod 32. By setting hexagonal bolts, one end of the grinding and cleaning belt 14 can be fixed to the rectangular connecting block 21. Then, the operation of the U-shaped mounting base 12 causes the rectangular rotating column 18 to rotate. The rotation of the rectangular rotating column 18 causes the rectangular transmission column 19 to move the L-shaped sliding column 20 outside the transverse sliding box 8. This allows the L-shaped sliding column 20 to reciprocate outside the transverse sliding box 8. The movement of the L-shaped sliding column 20 causes the grinding and cleaning belt 14 to move through the rectangular connecting block 21. This allows the rectangular slider 16 to move inside the transverse sliding box 8. The movement of the rectangular slider 16 causes the longitudinal rigid spring 17 to deform under force. The reciprocating motion of the grinding and cleaning belt 14 allows the inside of the transverse connecting screening rod 32 to be cleaned. When the second drive motor 5 is operated, the grinding and cleaning belt 14 can move laterally outside the transverse connecting screening rod 32.

[0036] The transverse sliding box 8 and the airflow box 10 can move laterally, which can clean the bottom of the transverse screening cylinder 3. By rotating the transverse screening cylinder 3, the periphery of the transverse screening cylinder 3 can be cleaned. Through the setting of the motion mechanism, the grinding and cleaning belt 14 can perform deep cleaning of the interior of the transverse connecting screening rod 32, achieving an internal cleaning effect that is difficult to achieve by traditional cleaning methods, and significantly reducing the clogging rate.

[0037] Working principle: The operation of the second drive motor 5 enables the transverse threaded rod 6 to rotate. The rotation of the transverse threaded rod 6 enables the transverse sliding box 8 to move laterally outside the transverse smooth rod 7. The movement of the transverse sliding box 8 enables the transverse position of the airflow box 10 to be adjusted. Through an external pump or an external pump connected to the connecting air pipe 11, the airflow box 10 can spray cleaning liquid or spray high-pressure airflow, so that the airflow box 10 can clean the dust on the outside of the transverse connecting screening rod 32.

[0038] One end of the grinding and cleaning belt 14 is wrapped around the outside of the transverse connecting screening rod 32. A hexagonal bolt is used to fix one end of the grinding and cleaning belt 14 to the rectangular connecting block 21. Then, the operation of the U-shaped mounting base 12 causes the rectangular rotating column 18 to rotate. The rotation of the rectangular rotating column 18 causes the rectangular transmission column 19 to move the L-shaped sliding column 20 outside the transverse sliding box 8, thus allowing the L-shaped sliding column 20 to reciprocate outside the transverse sliding box 8. The movement of the L-shaped sliding column 20, through the rectangular connecting block 21, allows the grinding and cleaning belt 14 to move, which in turn allows the rectangular slider 16 to move inside the transverse sliding box 8. The movement of the rectangular slider 16 causes the longitudinal rigid spring 17 to deform under force. The reciprocating motion of the grinding and cleaning belt 14 cleans the inside of the transverse connecting screening rod 32. When the second drive motor 5 operates, the grinding and cleaning belt 14 moves laterally outside the transverse connecting screening rod 32.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
