[0032] In another embodiment provided by the present invention, refer to Figure 8-12 , and also includes an opening and closing mechanism, which can drive the cross cover 3 to slide in the guide groove 2.

[0033] In another embodiment provided by the present invention, the opening and closing mechanism includes a first rod body 12, which slides through the through hole in the center of the cross cover 3, that is, the first rod body 12 can slide in the through hole, but cannot rotate in the through hole, the first rod body 12 coincides with the axis of the sleeve 1, the top of the first rod body 12 is rotatably connected with a bolt 14, the inner wall of the through hole has an internal thread, and the bolt 14 can be threadedly connected with the through hole when following the first rod body 12 to move to the through hole, the first rod body 12 can move through the center of the cross ring 5, that is, the first rod body 12 can slide and rotate relative to the cross ring 5, the bottom of the first rod body 12 is slidably connected with a second rod body 13, the second rod body 13 cannot rotate relative to the first rod body 12, and a limiting structure of sliding stroke is provided between the second rod body 13 and the first rod body 12, that is, the limiting structure can limit the sliding distance between the second rod body 13 and the first rod body 12, and the bottom center of the barrel body 100 is opened. A through groove 15 is provided, and the second rod body 13 slides through the through groove 15 in a sealing manner, that is, the second rod body 13 and the through groove 15 are dynamically sealed and connected, the second rod body 13 can slide in the through groove 15, but cannot rotate in the through groove 15, at least one spiral groove 16 is provided on the circumferential side of the second rod body 13, and a sliding ball 17 corresponding to the spiral groove 16 is provided on the inner wall of the through groove 15, or a sliding ball 17 is provided on the circumferential side of the second rod body 13, and a spiral groove 16 is provided on the inner wall of the through groove 15, and the sliding ball 17 slides or rolls with the spiral groove 16, and a flat plate 18 is rotatably connected to the bottom of the second rod body 13, and a spring 19 is provided between the second rod body 13 and the bottom of the barrel body 100, and the elastic force of the spring 19 acts downward on the second rod body 13, and the specific spring 19 is sleeved on the second rod body 13, one end of the spring 19 is movably abutted against the bottom of the barrel body 100, and the other end is movably abutted against the limit block on the second rod body 13.

[0034] In this embodiment, when the bolt 14 is not threadedly connected to the through hole, such as when the material in the plastic barrel is not unsealed, the plate 18 is attached to the bottom of the barrel body 100, the spring 19 is elastically deformed, and the plastic barrel can be sealed and placed. Fig. 9When the material in the plastic barrel needs to be used and the cross cover 3 needs to be opened, the plastic barrel is lifted. At this time, the elastic force of the spring 19 is released, so that the second rod 13, the plate 18, the first rod 12 and the bolt 14 move downward relative to the cross cover 3, and the plate 18 is separated from the bottom of the barrel 100. The bolt 14 is located at the through hole. The bolt 14 is screwed so that the bolt 14 is threadedly connected to the through hole, so that the first rod 12 and the cross cover 3 are relatively fixed. Then the plastic barrel is put down, the spring 19 is elastically deformed, and the plate 18 first abuts against the placement platform (such as the ground, desktop, etc.). As the plastic barrel continues to be lowered, the cross cover 3 presses down the first rod 12 through the bolt 14, and the first rod 12 and the barrel 100 slide relative to the second rod 13. At the same time, the spiral slide groove 16 and the sliding ball 17 slide relative to each other, so that the second rod 1 3 rotates, and the second rod body 13 drives the first rod body 12 and the cross cover 3 to rotate together, so that the sliding part 3.3 of the cross cover 3 slides from the inside of the horizontal section 2.1 to the place where the horizontal section 2.1 and the spiral section 2.2 are connected; as the plastic barrel continues to be lowered, the cross cover 3 continues to press the first rod body 12 downward through the bolt 14. At this time, the first rod body 12 can no longer slide relative to the second rod body 13 due to the obstruction of the limiting structure. Therefore, the first rod body 12 and the second rod body 13 drive the cross cover 3 to slide relative to the barrel body 100 and the sleeve 1, and at the same time, the spiral slide groove 16 and the sliding ball 17 slide relative to each other, so that the second rod body 13, the first rod body 12 and the cross cover 3 slide and rotate relative to the sleeve 1, so that the sliding part 3.3 of the cross cover 3 slides in the spiral section 2.2, and the cross cover 3 is opened from the sleeve 1. Fig.10 When unloading, just insert the suction pipe of the suction pump into the barrel body 100 from the mouth of the sleeve 1; when it is necessary to close the cross cover 3, unscrew the bolt 14 from the through hole, rotate and press the cross cover 3 downward, the cross cover 3 drives the first rod body 12 and the second rod body 13 to move together, the cross cover 3 slides to the intersection of the spiral section 2.2 and the horizontal section 2.1, and continues to rotate the cross cover 3. The cross cover 3 drives the second rod body 13 to rotate through the first rod body 12. The second rod body 13 slides relative to the second rod body 13 and the cross cover 3 through the sliding cooperation between the spiral slide groove 16 and the sliding ball 17. At the same time, the sliding part 3.3 of the cross cover 3 slides to the inside of the horizontal section 2.1, and the cross cover 3 is closed. If the plastic barrel topples over due to external factors when the cross cover 3 is open, during the tipping process, since the flat plate 18 is no longer pressed on the placement platform, the elastic force of the spring 19 is quickly released, causing the second rod 13, the first rod 12 and the cross cover 3 to slide, and the cross cover 3 quickly covers the mouth of the sleeve 1. Fig.11 , thereby preventing the material in the barrel 100 from leaking. If the material needs to be dumped, just tilt the plastic barrel, then press the flat plate 18 or rotate the cross cover 3 by a tool, and the opening degree of the cross cover 3 can be adjusted by controlling the pressing depth of the flat plate 18 or the rotation angle of the cross cover 3.
