[0027] Embodiment:

[0028] As shown in the attached Figure 1 to the attached Figure 6 figure:

[0029] The present utility model provides a dust removal pipeline structure, including a pipe head 1. The top of the pipe head 1 is connected to an installation flange 2. Through the flange 2, the pipe head 1 is installed inside the oil tea shelling machine. As Figure 3 shown, the pipe head 1 is installed inside the dust removal cover of the shelling machine and is connected to the telescopic pipe for dust suction outside the dust removal cover. The suction generated by the telescopic pipe is transmitted to the inside of the oil tea shelling machine through the pipe head to remove impurities and dust inside it.

[0030] At the bottom of the pipe head 1, there is a connecting ring 3. An installation ring 4 is sleeved on the connecting ring 3, and an anti-backflow mechanism 5 is installed at the bottom to prevent the dust and dander attached to the inner wall of the telescopic pipe from falling back into the internal part of the shelling machine again;

[0031] The anti-backflow mechanism 5 includes a supporting ring 501 and an inner ring 502. The supporting ring 501 is installed at the bottom of the installation ring 4. Between the supporting ring 501 and the inner ring 502, there is a dust collection bag 503. The dust collection bag 503 is annular and its cross-section is funnel-shaped. In this embodiment, the dust collection bag 503 is a film made of PE material and has certain plasticity. When the dust suction work stops, the dust collection bag 503 can collect the dust and dander falling from the inner wall of the telescopic pipe. When cleaning, the dust collection bag 503 can be turned up to facilitate the cleaning of dust and dander.

[0032] Moreover, the anti-backflow mechanism can be replaced. For example, Figure 2 and Figure 4 As shown, at the top of the supporting ring 501, there is an installation buckle 504. At the bottom of the installation ring 4, there is a circle of movable grooves 401. There is a cavity in the movable groove 401. The width of the cavity is greater than the width of the movable groove 401. A notch 402 matching the installation buckle 504 extends from the side wall of the movable groove 401. The notch 402 communicates with the cavity. When connecting the installation ring 4 and the supporting ring 501, just pass the installation buckle 504 into the cavity through the notch 402, and then rotate the supporting ring 501 to make the installation buckle 504 leave the notch 402 position. And the narrow end at the bottom of the installation buckle 504 is stuck in the movable groove 401, and the wide position at the top of the installation buckle 504 is stuck in the cavity, completing the connection between the supporting ring 501 and the installation ring 4. And to disassemble the supporting ring 501, just rotate the supporting ring 501 again until the installation buckle 504 corresponds to the notch 402 position, making the disassembly and assembly more convenient.

[0033] For example, Figure 5 As shown, at least one operation groove 505 is opened at the bottom of the supporting ring 501 to facilitate the operation of rotating the supporting ring 501.

[0034] Among them, the installation ring 4 can also be disassembled. For example, Figure 1 and Figure 2 As shown, a thread groove 3 is opened on the circumferential side of the connecting ring 3. The installation ring 4 is sleeved outside the connecting ring 3 and is threadedly connected with the connecting ring 3 through the thread groove 3. The installation ring 4 can be disassembled or installed by rotating. A plurality of friction teeth 8 are circumferentially distributed on the circumference of the installation ring 4 to avoid slipping. The inner wall of the pipe head 1 is closely attached with a patch 6. The patch 6 is connected to the inner side of the installation ring 4 through an arc-shaped connecting arm 7. The setting of the patch 6 enables the patch 6 to pick up the dust and other impurities on the inner wall of the pipe head 1 during the process of disassembling the installation ring 4, making them fall into the dust collection bag 503, keeping the inner side of the port of the pipe head 1 clean, and avoiding residual impurities from falling into the shelling machine during the process of disassembling and replacing the dust collection bag 503, making the dust removal work in the shelling machine more thorough.

[0035] The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles of the present utility model and its practical application, and to enable those of ordinary skill in the art to understand the present utility model so as to design various embodiments with various modifications suitable for a particular purpose.
