[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figure 1-6 shown, the present utility model provides a technical solution: a finished tea screening device, which includes a screening box 1. A fan 2 is installed at the front side port of the screening box 1. A feed hopper 3 is installed at the top side of the front end of the screening box 1. The bottom outlet of the feed hopper 3 is arranged directly opposite to the fan 2, and the bottom outlet of the feed hopper 3 is strip-shaped, so that the tea leaves fall in a dispersed state. A conical sieve plate 4 is installed at the rear side inside the screening box 1. The diameter of the sieve holes of the conical sieve plate 4 is smaller than the diameter of the finished tea leaves, and the tip of the conical sieve plate 4 faces the fan 2. An outlet 5 is formed between the edge of the conical sieve plate 4 and the inner wall of the screening box 1. The rear side of the conical sieve plate 4 is connected to a conical collecting plate 6. The rear tip of the conical collecting plate 6 is connected to a slag discharge cylinder 7. A cloth bag 10 is arranged at the rear end of the slag discharge cylinder 7. The mouth of the cloth bag 10 is sleeved and fixed at the rear end of the slag discharge cylinder 7, and the cloth bag 10 is an exhaust filter bag. In this way, impurities can be filtered out and collected inside the cloth bag 10, and the gas can be discharged, ensuring the normal discharge of the gas inside the screening box 1. A discharge box 9 is fixedly arranged at the bottom side of the rear end of the screening box 1. After the tea leaves are put in through the feed hopper 3, under the guidance of the wind blown by the fan 2, the tea leaves can reach the conical sieve plate 4 along with the air flow, and the tea leaves move backward along the conical surface of the conical sieve plate 4. The sieve holes of the conical sieve plate 4 can screen out small particle tea leaves and impurities. And under the guidance of the air flow, the small particle tea leaves and impurities screened out can be collected through the conical collecting plate 6, the slag discharge cylinder 7 and the cloth bag 10. When the large particle tea leaves move to the rearmost side along the conical surface of the conical sieve plate 4, the tea leaves will be concentrated at the rear end of the screening box 1 through the outlet 5, and then discharged through the discharge box 9, realizing the screening out of the small particle tea leaves and impurities in the tea leaves. A cleaning structure is arranged on the conical sieve plate 4. The cleaning structure includes a shaft rod 11 and two cleaning rods 12. The two cleaning rods 12 are in the shape of sheet-like blades, and the shaft rod is connected to the tip of the conical sieve plate 4 through a bearing. And the two cleaning rods 12 are installed on the shaft rod 11, and the cleaning brushes at the rear sides of the two cleaning rods 12 are attached to the conical surface of the conical sieve plate 4. During the screening process, the cleaning rods 12 in the shape of blades can rotate along with the shaft rod 11 under the blowing of the fan 2. When the cleaning rods 12 rotate, the cleaning brushes at the rear sides can be attached to the conical surface of the conical sieve plate 4 for cleaning, avoiding the blockage of the sieve holes of the conical sieve plate 4 by the tea leaves. A control switch 8 is installed on the screening box 1, and the control switch 8 is electrically connected to the fan 2.

[0026] The operation steps of the present utility model are as follows:

[0027] After the tea leaves are put into the feeding hopper 3, under the guidance of the air blown by the fan 2, the tea leaves can move with the airflow onto the conical sieve plate 4, and the tea leaves move backward while adhering to the conical surface of the conical sieve plate 4. The sieve holes of the conical sieve plate 4 can screen out small particle tea leaves and impurities. And under the guidance of the airflow, the small particle tea leaves and impurities can be collected through the conical collecting plate 6, the slag discharge cylinder 7 and the cloth bag 10. When the large particle tea leaves move to the rearmost side along the conical surface of the conical sieve plate 4, the tea leaves will be concentrated at the rear end of the screening box 1 through the discharge port 5, and then discharged through the discharge box 9, realizing the screening of small particle tea leaves and impurities in the tea leaves. And during the screening process, the cleaning rod 12 in the shape of a paddle can rotate along with the shaft rod 11 under the blowing of the fan 2. When the cleaning rod 12 rotates, the cleaning brush at the rear side can adhere to the conical surface of the conical sieve plate 4 for cleaning, avoiding the blockage of the sieve holes of the conical sieve plate 4 by the tea leaves.
