Description

Technical Field

[0001] This utility model relates to the field of tea preparation technology, specifically to a self-cleaning tea drum sorting device. Background Technology

[0002] In the field of tea processing technology, tea sorting is a crucial step in ensuring tea quality. Its core objective is to efficiently separate tea leaves from impurities such as dust and debris, while minimizing damage during the sorting process to preserve the tea's integrity and quality. This step requires specialized equipment to turn and sift the tea leaves, and to remove impurities through rational mechanical design. Therefore, developing optimized, highly efficient tea drum sorting equipment has significant practical application value.

[0003] Currently, existing tea drum sorting equipment has a relatively simple turning path for tea leaves, making it difficult to achieve a three-dimensional turning effect inside the drum. This results in some tea leaves not being able to fully contact the inner wall of the drum, and the dust removal is not thorough. At the same time, the dust removal process of the equipment often relies on manual operation or a fixed-angle inclined structure, which cannot be dynamically adjusted according to the dust accumulation. This can easily lead to problems such as untimely dust removal or tea leaf loss, affecting the sorting effect and production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a self-cleaning tea drum sorting device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] Self-cleaning tea drum sorting equipment, including

[0007] Horizontal support tube;

[0008] An elliptical drum for stir-frying tea leaves has two ends through which dust can pass. Its rotation is set inside the support tube. A spherical part is fixed coaxially on the circumferential side of the elliptical drum. A toothed ring is adapted to the circumferential side of the spherical part, and the toothed ring is coaxial with the support tube.

[0009] A spiral track is provided on the circumferential side of the elliptical roller near one end;

[0010] The sliding shaft has one end slidably mounted on the inner wall of the spiral track, and the other end slidably mounted on the inner cavity of the support tube. Its sliding path is parallel to the axial direction of the support tube.

[0011] During the sliding process of the sliding shaft, the elliptical drum is driven to rotate in any direction to stir-fry the tea leaves with the help of the spiral track. When the two ends of the elliptical drum are tilted downwards, the dust is poured out.

[0012] Preferably, a T-shaped guide groove is provided on the peripheral side of the missing sphere, and a T-shaped guide block is fixed on the inner wall of the toothed ring and slides with the inner wall of the T-shaped guide groove. The two ends of the T-shaped guide groove point to the two ends of the elliptical roller.

[0013] Preferably, the bottom of the support tube is symmetrically fixed with oppositely arranged L-shaped shafts, the side of the toothed ring is symmetrically provided with annular grooves, and the top of the L-shaped shaft is embedded in the annular groove. When the toothed ring rotates, the L-shaped shaft and the annular groove slide together.

[0014] Preferably, the elliptical roller is provided with detachable mesh screens at both ends, and the mesh screens have a smaller aperture than the tea leaves.

[0015] Preferably, the length of the major axis of the elliptical outer shell corresponding to the elliptical roller is 1.5-2 times the length of the minor axis.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model guides the rotation of the elliptical drum by setting a spiral track and a sliding shaft. When the end of the elliptical drum tilts downward, dust will leak out from the holes in the screen, thus separating tea leaves from dust.

[0018] 2. The eccentric rotation of the elliptical drum and the oscillating action of the toothed ring of this utility model create a three-dimensional frying path for the tea leaves inside the elliptical drum, avoiding the accumulation of tea leaves caused by the unidirectional rotation of traditional drums, ensuring that each tea leaf is in full contact with the inner wall of the drum, and improving the efficiency of dust removal.

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] Example

[0027] like Figure 1 As shown, the self-cleaning tea drum sorting device includes a horizontally placed support pipe 1, with support legs fixed to the bottom surface of the support pipe 1, forming a horizontally placed rigid frame to support the entire device.

[0028] Preferred, such as Figure 2 , Figure 4 As shown, the elliptical roller 2, which can stir-fry tea leaves, has two ends through which dust can pass. Its rotation is set in the inner cavity of the support tube 1. The two ends of the elliptical roller 2 are provided with detachable mesh 11, which are connected by threads or buckles. The aperture of the mesh 11 is smaller than the aperture of the tea leaves, ensuring that the tea leaves are retained while dust and debris pass through.

[0029] Preferred, such as Figure 1-4 As shown, a missing ball 3 is fixed coaxially on the side of the elliptical roller 2. A toothed ring 4 is adapted on the side of the missing ball 3. The toothed ring 4 is coaxial with the support tube 1. A T-shaped guide groove 7 is opened on the side of the missing ball 3. A T-shaped guide block 8 is fixed on the inner wall of the toothed ring 4 and slides with the inner wall of the T-shaped guide groove 7. The two ends of the T-shaped guide groove 7 point to the two ends of the elliptical roller 2.

[0030] The missing sphere 3 is an irregular structure (a sphere with a partially missing spherical surface) that is coaxially fixed to the elliptical roller 2. The T-shaped guide groove 7 on its periphery is in sliding fit with the T-shaped guide block 8 on the inner wall of the toothed ring 4. The plane in which the toothed ring 4 rotates is perpendicular to the T-shaped guide groove 7. Therefore, when the toothed ring 4 rotates, it will drive the missing sphere 3 to rotate, which in turn will drive the elliptical roller 2 to rotate.

[0031] A drive gear is rotatably mounted on the inner wall of the support tube 1. Driven by a motor, the drive gear meshes with a gear ring 4. When the motor starts, it drives the drive gear to rotate, which in turn drives the gear ring 4 to rotate. The gear ring 4, limited by the T-shaped guide block 8 and the T-shaped guide groove 7, drives the elliptical roller 2 to rotate.

[0032] The bottom of the support tube 1 is symmetrically fixed with oppositely arranged L-shaped shafts 9. The toothed ring 4 has symmetrically opened annular grooves 10 on its side. The top of the L-shaped shaft 9 is embedded in the annular groove 10. When the toothed ring 4 rotates, the L-shaped shaft 9 and the annular groove 10 slide together. The cooperation between the L-shaped shaft 9 and the annular groove 10 provides stable support for the toothed ring 4.

[0033] Preferred, such as Figure 1-2 As shown, the spiral track 5 is located on the side of the elliptical roller 2 near one end.

[0034] The sliding shaft 6 has one end slidably mounted on the inner wall of the spiral track 5 and the other end slidably mounted on the inner cavity of the support tube 1. Its sliding path is parallel to the axial direction of the support tube 1. An electric telescopic rod is fixed to the side of the support tube 1. The telescopic end of the electric telescopic rod is fixedly connected to the sliding shaft 6 and is used to drive the sliding shaft 6 to slide along the axial direction of the support tube 1. When the sliding shaft 6 moves back and forth along the axial direction of the support tube 1, the spiral pattern of the spiral track 5 forces the elliptical drum 2 to rotate, thereby realizing the tea leaves being stir-fried. The closer the sliding shaft 6 is to the end of the elliptical drum 2, the greater the amplitude of rotation of the elliptical drum 2, and thus the greater the degree of stir-frying.

[0035] Meanwhile, since the elliptical roller 2 has an arc-shaped side, the distance between it and the sliding shaft 6 is variable, but the distance between the sliding shaft 6 and the spiral track 5 is fixed. When the sliding shaft 6 slides to the end of the spiral track 5 near the elliptical roller 2, the elliptical roller 2 will deflect and tilt towards the sliding shaft 6. As the elliptical roller 2 is rotating, when the sliding shaft 6 moves from the middle to the end of the elliptical roller 2, the elliptical roller 2 will slowly tilt in any direction from a horizontal position. When the end of the elliptical roller 2 tilts downward, the dust will leak out from the holes on the screen 11, thus separating the tea leaves from the dust. In this way, the tea leaves are stir-fried and the dust is cleaned at the same time during the rotation of the elliptical roller 2.

[0036] Preferred, such as Figure 1 As shown, the length of the major axis of the elliptical outer shell corresponding to the elliptical drum 2 is 1.5-2 times the length of the minor axis. This ratio causes the elliptical drum 2 to produce a non-uniform rotation effect when it rotates: the linear velocity at the end of the major axis is larger, which enhances the tea leaf scattering and tumbling; the linear velocity at the end of the minor axis is smaller, which facilitates dust settling and improves sorting efficiency.

[0037] Working principle: Feeding stage: Open the screen 11, pour the tea leaves to be sorted into the elliptical drum 2, and finally install the screen 11;

[0038] Sorting stage: The electric telescopic rod is started to drive the sliding shaft 6 to reciprocate along the axis of the support tube 1. The elliptical drum 2 rotates synchronously and swings eccentrically. The tea leaves are guided by the spiral track 5 to spiral up and fall along the inner wall of the elliptical drum 2, realizing particle grading and dust separation.

[0039] Self-cleaning stage: As the tea leaves are stir-fried for a longer time, more and more dust accumulates. When the elliptical roller 2 is deflected by the spiral track 5 so that its end is tilted downwards, the dust will leak out from the holes in the mesh 11, automatically separating the tea leaves and dust.

[0040] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
