Description

Technical Field

[0001] This utility model relates to the field of tea drying technology, and in particular to a drum-type tea drying device. Background Technology

[0002] Utility model CN222086513U relates to the field of tea production drying technology and discloses a drying device for tea production, including a supporting mechanism and a drying mechanism. The drying mechanism is fixedly connected to the top of the supporting mechanism. The drying mechanism includes a heating unit and a turning unit. The heating unit is fixedly connected to the top of the supporting mechanism, and the turning unit is rotatably connected to the interior of the heating unit. This drying device for tea production uses a drum-turning drying method, allowing tea leaves of different sizes to be turned over inside. The surface filter mesh allows the device to discharge dust particles and impurities during use. The receiving shell located directly below the supporting frame can receive the filtered dust and impurities and can also hold the dried tea leaves. The open design effectively discharges water vapor, improving efficiency and reducing space occupancy.

[0003] After searching, it was found that the existing technology has certain defects. Because the drum is always rotating in a single radial direction, the tea leaves inside are always piled up at the bottom of the drum and cannot be dispersed and piled up smoothly along the axial direction of the drum. This easily forms tea piles within a certain range, which reduces the drying efficiency of the tea leaves and easily leads to local overheating or uneven drying. Therefore, a drum-type tea drying device is needed to meet people's needs. Utility Model Content

[0006] Preferably, one side of the device housing is open, and a hatch is movably connected to it via a hinge and locking device.

[0007] Preferably, an exhaust fan is provided on one side of the device housing.

[0008] Preferably, one side of the roller is open and a cover plate is movably connected to it via a hinge and locking device.

[0009] Preferably, a lifting ring is provided at the bottom of the horizontal section of the bracket, and several rollers are rotatably connected inside the lifting ring. The rollers are evenly arranged in a circular shape, and the outer wall of the rollers near the cover plate contacts the side of the rollers that are close to each other.

[0010] Preferably, the bracket is provided with a first lug, and a second rotating shaft is rotatably connected inside the first lug. The first lug is arranged on the side of the second helical gear away from the meshing surface. The bracket is provided with a second lug, and a second rotating shaft is rotatably connected inside the second lug. The second lug is arranged on the side of the second synchronous pulley close to the second helical gear.

[0011] The beneficial effects of this utility model are:

[0012] In this invention, the output shaft of the motor, connected to the first rotating shaft, drives the support to rotate. This causes the drum, the first synchronous pulley, the second helical gear, the second rotating shaft, the second synchronous pulley, and the synchronous belt connected to the support to revolve around the support. The second helical gear, while revolving on the meshing surface of the first helical gear, generates a self-rotation effect. Combined with the connection of the second rotating shaft and the transmission effect of the first synchronous pulley, the second synchronous pulley, and the synchronous belt, the drum rotates, realizing the three-dimensional movement of the tea leaves inside the drum. This effectively avoids the local accumulation of tea leaves and creates an axial dispersion effect within the drum, improving the uniformity and efficiency of drying. Attached Figure Description

One end of the second helical gear 8 is connected to a second rotating shaft 9, and one end of the second rotating shaft 9 is axially connected to a second synchronous pulley 10. A synchronous belt 11 drives the transmission between the second synchronous pulley 10 and the first synchronous pulley 6. A heating component 12 is mounted inside the device housing 1.

[0022] The output shaft of motor 2, connected to the first rotating shaft 3, drives the bracket 4 to rotate. This causes the drum 5, the first synchronous pulley 6, the second helical gear 8, the second rotating shaft 9, the second synchronous pulley 10, and the synchronous belt 11 connected to the bracket 4 to revolve around the bracket 4. The second helical gear 8 rotates on its own axis during its revolution on the meshing surface of the first helical gear 7. Combined with the connection of the second rotating shaft 9 and the transmission effect of the first synchronous pulley 6, the second synchronous pulley 10, and the synchronous belt 11, the drum 5 rotates, realizing the three-dimensional movement of tea leaves within the drum 5. This effectively avoids the local accumulation of tea leaves and causes the tea leaves to be axially dispersed within the drum 5, improving the uniformity and efficiency of drying.

[0023] Specifically, in this embodiment, one side of the device housing 1 is open, and a door 13 is movably connected to it via a hinge and locking device for loading and unloading tea leaves, thus preventing heat loss from the inside of the device housing 1.

[0024] Specifically, in this embodiment, an exhaust fan 14 is provided on one side of the device housing 1 to remove the moisture generated during the tea drying process.

[0025] Specifically, in this embodiment, one side of the roller 5 is open and is movably connected to a cover plate 15 by a hinge and locking device, which facilitates the loading and unloading of tea leaves and prevents the tea leaves from leaking out of the roller 5 during its dynamic rotation.

[0026] Specifically, in this embodiment, a lifting ring 16 is provided at the bottom of the horizontal section of the bracket 4. Several rollers 17 are rotatably connected inside the lifting ring 16. The rollers 17 are evenly arranged in a circumferential shape. The outer wall of the roller 5 near the cover plate 15 contacts the side of the rollers 17 that are close to each other, providing stable support for the rotation of the roller 5.

[0027] Specifically, in this embodiment, a first lug 18 is provided on the bracket 4, and a second rotating shaft 9 is rotatably connected inside the first lug 18. The first lug 18 is arranged on the side of the second helical gear 8 away from the meshing surface. A second lug 19 is provided on the bracket 4, and a second rotating shaft 9 is rotatably connected inside the second lug 19. The second lug 19 is arranged on the side of the second synchronous pulley 10 close to the second helical gear 8, to ensure the stability of the meshing between the second helical gear 8 and the first helical gear 7, as well as the transmission stability between the first synchronous pulley 6, the second synchronous pulley 10 and the synchronous belt 11.
