[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Reference Figures 1-6This utility model provides a sealed mobile hopper for a fully sealed turnover process, including a hopper body 1. A feed pipe 2, communicating with the inside of the hopper body 1, is bolted to the top of the hopper body 1. A pipe cover 3 is slidably connected to the feed pipe 2. A fixing assembly 9 is provided between the pipe cover 3 and the feed pipe 2 to fix the pipe cover 3. An annular plate 10 is bolted to the top of the feed pipe 2. An annular groove 15 is formed on the upper surface of the annular plate 10. A U-shaped sliding plate 16 is slidably connected inside the annular groove 15. An annular U-shaped sealing gasket 17 is adhered to the surface of the U-shaped sliding plate 16, and the outer walls of the U-shaped sealing gasket 17 contact the inner walls of the annular groove 15. Multiple springs 18 are welded in a circular array on the top interior of the U-shaped sliding plate 16, and the other ends of the multiple springs 18 contact the bottom inner wall of the annular groove 15. After material is fed into the hopper body 1 from the feed pipe 2, the... The cover 3 is placed on the feed pipe 2. As the cover 3 moves downward along the outer wall of the feed pipe 2, it seals the pipe after the inner top wall of the cover 3 contacts the U-shaped sealing gasket 17. As the cover 3 continues to move downward, it compresses the U-shaped sliding plate 16 and the U-shaped sealing gasket 17, which move downward along the annular groove 15. At this time, the spring 18 is compressed. Through the U-shaped sliding plate 16 and the U-shaped sealing gasket 17, the cover 3 is placed on the feed pipe 2, and the cover 3 and the feed pipe 2 are in contact through the U-shaped sealing gasket 17, thus sealing the gap between them and preventing leakage that could contaminate the material in the hopper body 1. Through the spring 18, the side of the U-shaped sealing gasket 17 is always in the annular groove 15 while the top of the cover 3 is always in close contact with the inner top wall of the cover 3 during the downward movement of the cover 3, preventing shaking during the transfer process and the formation of gaps.

[0025] To facilitate the fixing of the feed pipe 2 and the pipe cover 3, the fixing assembly 9 includes multiple sets of fixing blocks 7, each set consisting of two blocks, which are bolted to the outer circumference of the pipe cover 3. The outer circumference of the feed pipe 2 is also bolted to multiple sets of fixing blocks 8, the same number as the sets of fixing blocks 7, and corresponding to each other. Each set consists of two fixing blocks 8. A rotating rod 11 is rotatably connected between the two fixing blocks 8 in each set via a bearing. A threaded rod 12 is welded to the outer circumference of the rotating rod 11, and a locking knob 13 is threaded onto the threaded rod 12. The lower surface of the locking knob 13 is in close contact with the upper surfaces of the two fixing blocks 7. A limiting mechanism is provided on the upper surface of each set of two fixing blocks 7. The bottom end of the locking knob 13 is embedded in the limiting groove 14. When the tube cap 3 needs to be installed on the feed pipe 2, the tube cap 3 is placed on the feed pipe 2 and slid downward. When it reaches the lowest point, the threaded rod 12 is rotated so that it moves along the rotating rod 11. When the rotating rod 11 rotates between the two fixed blocks 7, the locking knob 13 on it is rotated so that its lower surface is in close contact with the upper surface of the two fixed blocks 7. Through the fixed component 9, the tube cap 3 can be fixed after it is installed on the feed pipe 2, thereby preventing shaking during the transfer process and preventing gaps from forming between the feed pipe 2 and the tube cap 3, which would lead to a poor sealing effect between them.

[0026] To further improve the sealing performance of the device, an annular groove 19 is provided on the outer circumference of the feed pipe 2. A sealing ring 20 is bonded inside the annular groove 19. The width of the sealing ring 20 is smaller than the width of the annular groove 19, and the thickness of the sealing ring 20 is greater than the thickness of the annular groove 19. The outer ring of the sealing ring 20 is in close contact with the inner circumference of the pipe cover 3. When the pipe cover 3 moves downward, its inner circumference will squeeze the sealing ring 20, causing it to deform within the annular groove 19. The pipe cover 3 and the inner circumference of the feed pipe 2 are in close contact. Through the annular groove 19 and the sealing ring 20, the sealing ring 20 can be squeezed while the pipe cover 3 moves downward, making it in close contact with the inner circumference of the pipe cover 3. This provides a secondary seal between the pipe cover 3 and the feed pipe 2, further enhancing the sealing performance between them.

[0027] To facilitate material discharge, the bottom of the silo body 1 is provided with a discharge pipe 5 that is connected to its interior. The discharge pipe 5 is equipped with a discharge valve 6 for controlling the discharge. A movable frame 4 is fixedly connected to the outer circumference of the silo body 1 by bolts. When it is necessary to discharge the material in the silo body 1, the discharge valve 6 can be opened to discharge the material in the silo body 1.

[0028] The use of this utility model involves the following steps:

[0029] S1: After the material is fed into the hopper body 1 from the feed pipe 2, the pipe cover 3 is placed on the feed pipe 2. The pipe cover 3 moves down along the outer wall of the feed pipe 2. After the top inner wall of the pipe cover 3 contacts the U-shaped sealing gasket 17, the sealing work can be carried out. As the pipe cover 3 continues to move down, it will squeeze the U-shaped sliding plate 16 and the U-shaped sealing gasket 17 to move down along the annular groove 15. At this time, the spring 18 is compressed.

[0030] S2: During the process of installing the pipe cap 3 onto the feed pipe 2, slide the pipe cap 3 onto the feed pipe 2 downwards. When the lowest point of the slide is reached, rotate the threaded rod 12 so that it moves along the rotating rod 11. When the rotating rod 11 rotates between the two fixed blocks 7, rotate the locking knob 13 on it so that its lower surface is in close contact with the upper surface of the two fixed blocks 7.

[0031] S3: As the pipe cover 3 moves downward, its inner circumferential wall will squeeze the sealing ring 20, causing it to deform within the annular groove 19. The pipe cover 3 will be in close contact with the inner circumferential wall of the feed pipe 2. When it is necessary to discharge the material in the hopper body 1, the discharge valve 6 can be opened to discharge the material in the hopper body 1.

[0032] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.
