[0017] 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.

[0018] Please see Figure 1-4This utility model provides a technical solution: including a conveying trolley 1 and a loading barrel 2. The loading barrel 2 is fixed on the upper end of the conveying trolley 1. An upper end plate 3 is installed on the upper end of the loading barrel 2. The upper end plate 3 has a ring structure and is the same size as the upper opening of the loading barrel 2. A membrane sleeve 4 is fixed between the upper end of the loading barrel 2 and the upper end plate 3. A drive assembly for lifting and lowering the upper end plate 3 is provided on the outer wall of the loading barrel 2.

[0019] The drive assembly includes a threaded rod 51 and a threaded sleeve 61. An outer plate 5 is fixed around the upper end plate 3. The threaded rod 51 is fixedly connected to the bottom of the outer plate 5. A fixing plate 6 is fixedly connected to the outside of the loading barrel 2 at a position corresponding to the threaded rod 51. The threaded sleeve 61 is rotatably connected inside the fixing plate 6. The bottom of the threaded rod 51 passes through the threaded sleeve 61 and is threadedly connected to the threaded sleeve 61. An outer groove 62 is opened on the outside of the fixing plate 6. A transmission gear 63 is fixed on the outside of the threaded sleeve 61 at a position aligned with the outer groove 62. An annular plate 7 is rotatably connected around the fixing plate 6. An annular gear 71 that meshes with the transmission gear 63 is fixed on the inside of the annular plate 7 at a position aligned with the outer groove 62. A bevel gear sleeve 72 is fixed at the bottom of the annular plate 7. A drive motor 73 is fixed on the outside of the loading barrel 2. The output end of the drive motor 73 is located inside the annular plate 7 and is fixedly connected to a drive bevel gear that meshes with the bevel gear sleeve 72.

[0020] A cover plate 31 is fixed to the inner wall of the upper plate 3. An inlet and outlet 32 ​​are provided on the cover plate 31. A pair of slide rails 33 are fixed to the upper end of the cover plate 31. A sealing plate 34 is slidably connected to the slide rails 33. A groove is provided at the bottom of the sealing plate 34 and at a position corresponding to the slide rails 33. An anti-slip pad is fixed to the side wall of the groove.

[0021] Working principle: First, connect the entire device to the power supply. Then, using the drive motor 73 output and the transmission of the drive bevel gear and bevel gear sleeve 72, the annular plate 7 can be rotated. Then, using the transmission of the annular gear 71 and the transmission gear 63, the threaded sleeve 61 can be rotated synchronously, thereby realizing the extension and retraction drive of the threaded rod 51. When the threaded rod 51 moves upward, it can push the upper end plate 3 upward, which stretches the membrane sleeve 4, increasing the overall capacity of the container and thus increasing the single conveying capacity. Conversely, when the upper end plate 3 falls, it can reduce the overall height, making it easier to avoid obstacles during the conveying process. In addition, during the transportation process, the sliding of the high sealing plate 34 can seal the inlet and outlet 32, preventing powder material from spilling out. Furthermore, the anti-slip pad can increase the stability of the sealing plate 34 after it is covered.
