[0002] The internal spiral hollow tube device is a mechanical device used in specific industrial applications. This device is designed to improve material discharge efficiency, reduce material buildup inside the machine, and thus extend the machine's lifespan. The internal spiral hollow tube device is characterized by its internal spiral structure, which helps promote smooth material flow, reduces blockages, and effectively guides material discharge.

[0003] In existing internal spiral hollow tube devices, a large amount of deposits will accumulate in the internal spiral grooves after long-term use. These deposits will cause the internal spiral grooves to be filled, thereby damaging the spiral structure, reducing the smoothness of material flow, and increasing the probability of blockage. Utility Model Content

[0004] The purpose of this utility model is to provide an internal spiral hollow tube device. When material enters the tube and falls downwards, it will hit the baffle, which will generate a rotational force. This will cause the connecting block to rotate and move within the groove of the connecting ring via a slider. During the rotation, the brush cleans the inner wall of the tube, thereby preventing the spiral groove on the inner wall of the tube from being blocked. At the same time, the baffle is also spiral-shaped, which can promote the flow of material during the material conveying process and improve the material conveying efficiency. The overall structure is simple and highly practical.

[0005] To achieve the above objectives, an internal spiral hollow tube device is provided, comprising: a tube assembly and a connecting assembly. The tube assembly includes a tube body and spiral grooves. Multiple spiral grooves are evenly distributed on the inner circumferential surface of the tube body. The connecting assembly includes a connecting ring, an upper retaining groove, a sliding groove, a slider, a connecting block, an upper sealing ring, a connecting rod, a baffle, a brush, and a lower sealing ring. The bottom of the connecting ring is fixedly connected to the tube body. The top of the connecting ring has an upper retaining groove. The inner circumferential surface of the connecting ring has a sliding groove. A slider is slidably disposed inside the sliding groove. A connecting block is fixedly connected to the side of the slider away from the sliding groove. The connecting block is annular. An upper sealing ring is disposed above the connecting block. A connecting rod is fixedly connected to the bottom of the connecting block. A baffle is fixedly connected to the bottom of the connecting rod. A brush is fixedly connected to the baffle. A lower sealing ring is fixedly connected to the bottom of the connecting block. The lower sealing ring has a groove and engages with the connecting rod, the baffle, and the brush.

[0006] According to the aforementioned internal spiral hollow tube device, multiple connecting rods, baffles, and brushes are provided and evenly distributed below the connecting block. This makes it easier to rotate under force.

[0007] According to the aforementioned internal spiral hollow tube device, the brush is made of wear-resistant plastic and is located between the baffle and the tube body. It can clean the spiral grooves on the inner wall of the tube.

[0008] According to the aforementioned internal spiral hollow tube device, both the baffle and the brush are spiral-shaped and located inside the tube body. The width of the baffle is greater than the width of the connecting block, and it is used for conveying materials and receiving rotational force generated by the impact of materials during the conveying process.

[0009] According to the aforementioned internal spiral hollow tube device, two sliders are provided, symmetrically distributed inside the slide groove. When the baffle is impacted and generates a rotational force, the connecting block rotates and moves within the slide groove via the sliders.

[0010] According to the aforementioned internal spiral hollow tube device, the baffle is made of non-magnetic stainless steel plate, and the upper and lower surfaces are smoothed. It is sturdy and durable, not easily worn, and the smooth upper and lower surfaces prevent dust accumulation and facilitate material conveying.

[0011] According to the aforementioned internal spiral hollow tube device, the upper sealing ring and the connecting ring are engaged by an upper slot, and the upper sealing ring is made of wear-resistant rubber. The upper sealing ring is used to seal the upper part of the connecting ring and the connecting block, preventing dust from entering the interior of the slide groove and reducing the sliding force of the slider.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a connecting ring, upper slot, slide groove, slider, connecting block, sealing ring, connecting rod, baffle, and brush, when the material enters the pipe and falls downward, it will hit the baffle, and the baffle will generate a rotational force, thereby causing the connecting block to rotate and move within the slide groove through the slider inside the connecting ring. During the rotation, the brush cleans the inner wall of the pipe, thereby preventing the spiral groove on the inner wall of the pipe from being blocked. At the same time, the baffle is also spiral-shaped, which can promote the flow of material during the material conveying process and improve the material conveying efficiency. The overall structure is simple and highly practical.
