Description

Technical Field

[0001] The utility model belongs to the technical field of tea screening machines, and specifically relates to a tea screening machine. Background Art

[0002] Tea, commonly known as cha, generally includes the leaves and buds of tea plants. The components of tea include catechins, cholestenone, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. The tea beverages made from tea are one of the three major beverages in the world. Tea is divided into green tea, black tea, yellow tea, etc. Green tea is a shrub or small tree plant of the genus Camellia in the family Theaceae. Green tea has a natural shape and a fresh green color. It is made by taking the new leaves or buds of tea plants and going through processes such as fixation, shaping, and drying, retaining the natural substances of the fresh leaves. The tea leaves are pointed and thin, with a smooth surface. It has white flowers, which are small and polygon-shaped. And when producing green tea, a screening machine is needed to screen the green tea.

Outside the movable shaft 2, a movable frame 3 is movably connected. A connecting shaft 4 penetrates through the front surface of the movable frame 3 and is movably connected. One end of the connecting shaft 4 is fixedly connected to a screening frame 5. On one side of the screening frame 5, a transmission assembly is fixedly connected. At the bottom of the screening frame 5, a vibrator 10 is fixedly connected. Inside the bottom of the screening frame 1, a driving mechanism is fixedly connected;

[0026] At the bottom of the feeding hopper 14, a driving frame 16 is fixedly connected. On the front surface of the driving frame 16, a transmission wheel 17 is movably connected through a rotating shaft. On the back surface of the driving frame 16, a turntable 18 is movably connected through a rotating shaft. On the back surface of the turntable 18, a push-pull rod 19 is fixedly connected.

[0027] As can be seen from the above, when the driving motor 11 drives the transmission belt 13 to operate through the driving wheel 12, and the transmission belt 13 drives the turntable 18 to rotate through the transmission wheel 17, at the same time, the push-pull rod 19 will also rotate. When the push-pull rod 19 rotates, it will pull the connecting sleeve 503. The connecting sleeve 503 acts on the push-pull support 501 through the push-pull arm 502, thereby driving the screening frame 5. The screening frame 5 will move through the movable frame 3, the movable shaft 2 and the connecting shaft 4, and thus rock back and forth.

[0028] Embodiment 2: The driving mechanism includes a driving motor 11, a driving wheel 12 and a transmission belt 13. The driving motor 11 is fixedly connected to the inside of the bottom of the screening frame 1. The driving end of the driving motor 11 is fixedly connected to a driving wheel 12. The outside of the driving wheel 12 is movably connected to a transmission belt 13. The transmission belt 13 is movably connected to the transmission wheel 17.

[0029] As can be seen from the above, when the driving motor 11 drives the transmission belt 13 to operate through the driving wheel 12, and the transmission belt 13 drives the turntable 18 to rotate through the transmission wheel 17, at the same time, the push-pull rod 19 will also rotate.

[0030] Example 3: A coarse tea screening mesh 6 and a fine tea screening mesh 8 are respectively fixedly connected to the inner side of the screening frame 5. A first discharge hopper 7 is fixedly connected to the front of the screening frame 5, and a second discharge hopper 9 is fixedly connected to the back of the screening frame 5.

[0031] As can be seen from the above, when the coarse tea screening mesh 6 in the screening frame 5 vibrates and moves back and forth, it will screen the green tea, and the smaller tea leaves will fall onto the fine tea screening mesh 8, while some tea branches will be screened out through the fine tea screening mesh 8.

[0032] Example 4: The transmission assembly includes a push-pull bracket 501, a push-pull arm 502, and a connecting sleeve 503. The push-pull bracket 501 is fixedly connected to one side of the screening frame 5. The inner side of the push-pull bracket 501 is movably connected to the push-pull arm 502 through a pin. One end of the push-pull arm 502 is fixedly connected to the connecting sleeve 503, and the connecting sleeve 503 is movably connected to the push rod 19.

[0033] As can be seen from the above, when the push rod 19 rotates, it will pull the connecting sleeve 503. The connecting sleeve 503 acts on the push-pull bracket 501 through the push-pull arm 502, thereby driving the screening frame 5 to operate.

[0034] Example 5: The screening frame 5 is made of stainless steel material, and the outer surface of the screening frame 5 is smooth.

[0035] As can be seen from the above, the screening frame 5 made of stainless steel material is more durable and not easily damaged.

[0036] Example 6: A discharge partition 15 is movably connected to the top of the feeding hopper 14, and the outer width of the discharge partition 15 is adapted to the inner width of the feeding hopper 14.

[0037] As can be seen from the above, add green tea to the feeding hopper 14, and then pull up the discharge partition 15 to open the discharge port, so that the tea leaves fall onto the coarse tea screening mesh 6.

[0038] Working principle: When using the tea screening machine, the staff adds green tea into the feeding hopper 14, and then pulls up the discharge partition plate 15 to open the discharge port. At this time, the tea will fall onto the coarse tea screening mesh 6. Meanwhile, the vibrator 10 will operate to generate vibration, which acts on the screening frame 5. The drive motor 11 drives the conveyor belt 13 to rotate through the drive wheel 12, and the conveyor belt 13 drives the turntable 18 to rotate through the transmission wheel 17. At the same time, the push-pull rod 19 will also rotate. When the push-pull rod 19 rotates, it will pull the connecting sleeve 503, and the connecting sleeve 503 acts on the push-pull support 501 through the push-pull arm 502, thereby driving the screening frame 5. The screening frame 5 will move through the movable frame 3, the movable shaft 2 and the connecting shaft 4, and thus rock back and forth. At this time, the coarse tea screening mesh 6 in the screening frame 5 will screen the green tea due to vibration and repeated push-pull movements. The smaller tea leaves will fall onto the fine tea screening mesh 8, and some tea branches will be screened out through the fine tea screening mesh 8. In this way, the use process of the present utility model is completed. The structure of the present utility model is simple, and it is safe and convenient to use.
