[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides a tea leaf dust collection device, including a barrel screen 1 and a frame 2. The barrel screen 1 is set inside the frame 2. The frame 2 has an inclined angle. The barrel screen 1 also has an inclined angle under the support of the frame 2. The inclined angle of the barrel screen 1 facilitates the discharge of tea leaves inside to the outside.

[0023] A collection cover 3 is provided on the outside of the barrel sieve 1. The collection cover 3 forms a wrap around the outside of the barrel sieve 1, collecting the tea leaves separated by the barrel sieve 1 inside and preventing the tea leaves from splashing outward. A support 4 is connected to the outer surface of the collection cover 3. One side of the support 4 is connected to the inner wall of the frame 2. The support 4 supports the collection cover 3 and maintains its stability. There are two sets of support 4, with three in each set. The two sets of support 4 are located on both sides of the collection cover 3.

[0024] Below the collection hood 3 is a flow-concentrating hood 5. Tea fragments collected inside the collection hood 3 fall into the flow-concentrating hood 5 and are guided by the flow-concentrating hood 5 to be discharged into the collection box 6. The collection box 6 is installed below the frame 2. The bottom end of the flow-concentrating hood 5 is connected to the collection box 6. The inner wall of the collection box 6 has a drawer 7 that slides in contact with it. Tea fragments that fall into the collection box 6 enter the drawer 7 and are stored uniformly by the drawer 7.

[0025] The inner wall of the collecting cover 3 is connected to a circular guide rail 8, and the outer surface of the barrel screen 1 is connected to a circular wheel frame 9. Multiple support rollers 10 are rotatably connected to the inner wall of the circular wheel frame 9. The outer surfaces of the multiple support rollers 10 are in contact with the outer surface of the circular guide rail 8. The collecting cover 3 supports the support rollers 10 through the guide rail to maintain the stability of the support rollers 10 during rotation, and supports the support rollers 10 through the circular wheel frame 9 to maintain the stability of the support rollers 10. The support rollers 10 also support the barrel screen 1 to facilitate the rotation of the barrel screen 1.

[0026] A gear ring 11 is also connected to the outer surface of the barrel sieve 1. A motor 12 is installed on the inner wall of the frame 2. The output shaft of the motor 12 is connected to a gear 13. The gear 13 meshes with the gear ring 11. The motor 12 is the power source to provide power for the rotation of the barrel sieve 1. When the motor 12 rotates, it drives the gear 13 to rotate at the same time. The barrel sieve 1 receives power through the gear ring 11. After the gear 13 rotates, it drives the barrel sieve 1 to rotate through the gear ring 11. After the barrel sieve 1 rotates, the tea leaves inside continuously tumble. While the tea leaves are tumbling, the tea leaves discharge the internal fragments from the holes inside the barrel sieve 1. The discharged tea leaf fragments are collected inside by the collection cover 3.

[0027] Multiple scrapers 14 are connected to the outer surface of the sieve 1, and the multiple scrapers 14 are arranged in a circular array. The outer surface of the scrapers 14 slides in contact with the inner wall of the collection cover 3. When screening tea leaves, the sieve 1 separates the tea leaves from the inside of the tea leaves. To prevent the separated tea leaves from sticking to the inside of the collection cover 3, the scrapers 14 scrape off the tea leaves. Multiple brushes 15, the same number as the scrapers 14, are connected to the outer surface of the sieve 1, and the multiple brushes 15 are arranged in a circular array. The outer surface of the brushes 15 contacts the inner wall of the collection cover 3. The brushes 15 clean the inner wall of the collection cover 3 and clean the tea leaves that the scrapers 14 did not scrape off, preventing the tea leaves from sticking to the inside of the collection cover 3 and keeping the inside of the collection cover 3 clean.

[0028] Two support frames 16 are connected to the outer surface of the frame 2, and the two support frames 16 are symmetrical. The other end of the two support frames 16 is connected to the feed pipe 17, and the feed pipe 17 has an inclined angle. One end of the feed pipe 17 is located inside the barrel screen 1, and the other end of the feed pipe 17 located outside the barrel screen 1 is connected to the feed hopper 18. The support frames 16 support the feed pipe 17 to maintain its stability. The feed hopper 18 has a wide angle, which makes it easy to put tea leaves into the feed pipe 17 and transport the tea leaves close to the inside of the barrel screen 1 through the feed pipe 17.

[0029] The end of the sieve 1 away from the feed pipe 17 is connected to a discharge hood 19, which has an inclined angle. The discharge hood 19 guides the tea leaves and discharges them to the outside of the frame 2, making it easier to collect the screened tea leaves.

[0030] Working principle: First, start motor 12. After motor 12 starts, it drives gear 13 to rotate. After gear 13 rotates, it drives barrel screen 1 to rotate simultaneously through gear ring 11. Then, the tea leaves that are not screened are filled into feed pipe 17 through feed hopper 18. Then, the tea leaves in feed pipe 17 enter barrel screen 1. Under the rotation of barrel screen 1, the tea leaves inside are discharged through the holes inside barrel screen 1. After the tea leaves are discharged, they are confined inside by collection hood 3. Then, the tea leaves fall into flow gathering hood 5. Flow gathering hood 5 guides the tea leaves into collection box 6. Then, the tea leaves fall into drawer 7 and are collected.
