[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-3 As shown, the utility model provides a technical solution: an electric drum with a compacting structure, comprising a drum shell 1, a fixing seat 12 is provided on the inner wall of the drum shell 1, a motor 13 is fixedly connected to the fixing seat 12, the motor 13 is provided with a coupling 14 through an output shaft, a lower cover plate 20 is provided outside the coupling 14, the lower cover plate 20 is movably connected to the drum shell 1, and by providing the lower cover plate 20 and the upper cover plate 3, the lower cover plate 20 and the upper cover plate 3 can cooperate with the inner gear ring 19 to form a sealing structure, thereby wrapping the driving gear 15 and the surrounding gear 16 therein to prevent the outside from affecting the driving gear 15 and the surrounding gear 16;

[0020] A driving gear 15 is provided on the coupling 14. The outer gear of the driving gear 15 has a surrounding gear 16. There are two surrounding gears 16 and they are distributed in a ring array. The surrounding gear 16 is movably connected to the lower cover 20. A support rod 17 is provided outside the surrounding gear 16. The two ends of the support rod 17 are rotatably connected to the upper cover 3 and the lower cover 20. A linkage gear 18 is provided on the support rod 17. The outer teeth of the linkage gear 18 are connected to the inner ring gear 19. The inner ring gear 19 is fixedly connected to the drum shell 1. By providing the surrounding gear 16, the driving gear 15 drives the surrounding gear 16 to rotate, and then the surrounding gear 16 drives the linkage gear 18 to rotate around the driving gear 15 in the upper cover 3, thereby realizing rapid deceleration of the electric drum.

[0021] The inner gear ring 19 is movably connected to the lower cover plate 20. The upper cover plate 3 is arranged on the inner gear ring 19. The upper cover plate 3 is fixedly connected to the drum end cover 2. By providing the inner gear ring 19, the inner gear ring 19 drives the drum shell 1 to rotate, so that the drum shell 1 operates stably.

[0022] The drum shell 1 is movably connected to a drum end cover 2, the drum end cover 2 is fixedly connected to an upper cover plate 3, a fixed shaft 4 is provided on the upper cover plate 3, a pressing block 5 is movably connected to the outside of the fixed shaft 4, and a mounting bracket 6 is provided outside the pressing block 5. There are three mounting brackets 6 distributed in a circular array.

[0023] The mounting frame 6 is provided with a connecting rod 7 through a rotating shaft, and a linkage rod 8 is provided on one side of the connecting rod 7. Limiting shafts 9 are installed on both sides of the linkage rod 8. The limiting shafts 9 are movably connected to the roller end cover 2. A fastener 10 is provided on the end of the linkage rod 8 away from the connecting rod 7. The roller end cover 2 is provided with a movable groove 11 near the linkage rod 8. By providing the fastener 10, the support frame extends into the roller end cover 2 to extrude the pressure block 5, thereby driving the linkage rod 8 to rotate, so that the fastener 10 rests on the surface of the support frame. As the support frame continues to move downward, the fastener 10 clamps the support frame, thereby connecting and fixing the roller end cover 2 to the support frame.

[0024] The working principle of this utility model is:

[0025] When the electric drum and the support frame are assembled, the support frame extends into the drum end cover 2 to squeeze the pressure block 5, so that the pressure block 5 drives the mounting frame 6 to move into the electric drum, so that the connecting rod 7 in the mounting frame 6 moves with the pressure block 5 and squeezes one end of the linkage rod 8, so that the linkage rod 8 drives the fastener 10 to squeeze the support frame, thereby completing the rapid assembly of the electric drum and the support frame. Subsequently, when the electric drum is in use, the motor 13 drives the coupling 14 to rotate, and then the driving gear 15 rotates with the coupling 14. The driving gear 15 drives the surrounding gear 16 to rotate, and then the surrounding gear 16 drives the linkage gear 18 to rotate around the driving gear 15 in the upper cover 3. The linkage gear 18 is toothed with the inner ring gear 19, so that the linkage gear 18 drives the drum shell 1 outside the inner ring gear 19 to rotate, so that the motor 13 drives the drum shell 1 to rotate stably.
