The disc 6 drives the connecting rod 7 to move, and the connecting rod 7 rotates between the disc 6 and the rotating seat. As the disc 6 rotates, the connecting rod 7 is driven to continuously push and pull the impurity removal plate 3, so that the impurity removal plate 3 shakes and the inclination angle changes. During this process, the connecting rod 7 drives the slider 10 to slide on the outer surface of the slide rod 9 to prevent the angle of the impurity removal plate 3 from changing, thereby filtering and removing impurities in the tea leaves through the filter net 4, and the tea leaves roll indirectly onto another impurity removal plate 3 to perform the same impurity removal work, so that the tea leaves pass through two symmetrically cross-arranged impurity removal plates 3, so that the tea leaves are filtered multiple times and can be in a rolling state, thereby improving the filtering effect of the tea leaves.

[0022] The top outer surface of the impurity removal box 1 is fixedly connected to a feed hopper 11, and the outer surface of the feed hopper 11 is rotatably connected to two electrostatic adsorption rollers 12.

In this embodiment, the impurity removing plates 3 swing at 30 to 60 degrees, so that the tea leaves can roll, but will not quickly pass through the filter screen 4 and detach from the impurity removing plates 3, so that the tea leaves can stay on the filter screen 4 for filtering time.

[0025] A box door is provided on the front outer surface of the debris removal box 1, and a material receiving box is movably provided on the bottom inner surface of the debris removal box 1.

The two second impurity boxes 21 are respectively arranged on the left and right sides of the impurity removal box 1 and are located below the discharge trough 20. In this embodiment, the filtered dust and impurities fall onto the guide plate 19, and pass through the discharge trough 20 through the guide plate 19 to enter the second impurity box 21 for collection.

[0027] The left and right outer surfaces of the feed hopper 11 are both provided with a receiving groove 16, and one side of the electrostatic adsorption roller 12 extends to the outside of the receiving groove 16. The left and right outer surfaces of the feed hopper 11 are both fixedly connected with scrapers 17, and the two scrapers 17 are respectively in contact with the outer surfaces of the two electrostatic adsorption rollers 12, and the end of the scraper 17 in contact with the electrostatic adsorption roller 12 is an arc-shaped smooth surface. Two first impurity boxes 18 are provided on the top outer surface of the impurity box 1, and the two first impurity boxes 18 are respectively arranged under the two scrapers 17.

When a large amount of hair impurities are accumulated on the scraper 17 and cannot fall into the first impurity box 18 by themselves, the scraper 17 is cleaned manually.

[0028] Working principle: When the utility model is in use, the tea leaves that need to be cleaned are transported from the feed hopper 11 to the cleaning box 1, the tea leaves enter the cleaning box 1 and enter the cleaning plate 3, the first motor 5 works, the first motor 5 drives the disc 6 to rotate, the disc 6 drives the connecting rod 7 to move, the connecting rod 7 rotates between the disc 6 and the rotating seat, with the rotation of the disc 6, the connecting rod 7 is driven to continuously push and pull the cleaning plate 3, so that the cleaning plate 3 shakes and the inclination angle changes, so that the impurities in the tea leaves are filtered and cleaned through the filter screen 4, and in this process, the connecting rod 7 drives the slider 10 on the surface of the slider 9 The tea leaves slide on the guide plate 19 to prevent the angle of the impurity removal plate 3 from changing, and the tea leaves roll indirectly onto the other impurity removal plate 3 to perform the same impurity removal work. As a result, the tea leaves pass through two symmetrically cross-arranged impurity removal plates 3, which allows the tea leaves to be filtered multiple times and can be in a rolling state, thereby improving the filtering effect of the tea leaves and increasing the cleanliness of the tea leaves. The filtered dust and impurities fall onto the guide plate 19, and pass through the guide plate 19 through the discharge chute 20 into the second impurity box 21 for collection. The tea leaves finally fall into the receiving box at the bottom of the impurity removal box 1 for collection, and the box door can be opened to pull out the receiving box.

[0029] When the tea leaves are transported from the feed hopper 11 to the impurity removal box 1, the tea leaves are indirectly fed into the feed hopper 11, and then indirectly fed into the impurity removal box 1, thereby improving the impurity removal effect. When the tea leaves pass through the impurity removal box 1, the second motor 13 drives the electrostatic adsorption roller 12 at its output end to rotate, and drives the transmission wheel 14 thereon to rotate. Under the action of the belt 15, the other transmission wheel 14 is rotated, and then the two electrostatic adsorption rollers 12 are rotated at the same time, and then the hair and other impurities in the tea leaves can be adsorbed by the electrostatic adsorption roller 12, thereby improving the impurity removal effect. Through the rotation of the electrostatic adsorption roller 12, the impurities on the surface of the electrostatic adsorption roller 12 are cleaned under the action of the scraper 17, and the impurities are collected in the first impurity box 18. When a large amount of hair impurities are accumulated on the scraper 17 and cannot fall into the first impurity box 18 by themselves, the scraper 17 is cleaned manually.
