[0002] Tea refers to the leaves and buds of the tea tree. Tea originated in China and has a long history. It has many varieties, the most common ones are green tea, black tea, oolong tea, dark tea, white tea, yellow tea, etc. Green tea is an unfermented tea with clear soup and green leaves, and a fresh taste. Black tea is a fully fermented tea with red leaves and red soup, and a strong aroma. Oolong tea is a semi-fermented tea, which has the fragrance of green tea and the mellowness of black tea. Black tea is a post-fermented tea and usually has a unique aged fragrance. White tea is covered with white hairs on the surface, and the taste is light and sweet. The characteristic of yellow tea is yellow leaves and yellow soup. Tea contains a variety of beneficial ingredients, such as tea polyphenols, caffeine, theanine, etc., which have many effects such as refreshing, anti-oxidation, lipid-lowering and weight loss, antibacterial and anti-inflammatory.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figure 1-4The utility model provides a technical solution: a tea leaf crushing screening device, comprising a box body 1, which is placed on a flat ground. A rotating drum 2 is rotatably installed inside the box body 1. Tea leaves are inside the rotating drum 2, and the crushed tea leaves are separated by the reciprocating rotation of the rotating drum 2. The rotating shaft of the rotating drum 2 is perpendicular to the rear side plate of the box body 1, and the rotating shaft is rotatably connected to the rear plate of the box body 1. A blocking bar 201 is fixedly connected to the inside of the rotating drum 2. The rotating drum 2 reciprocates, and the blocking bar 201 can prevent the tea leaves from being thrown out from the gap above the rotating drum 2, and there are both sides. A gear 202 is fixedly installed on the rear side of the rotating drum 2. The rotating drum 2 and the gear 202 are a whole and rotate together. A motor 3 is fixedly installed on the outer side of the box body 1, and a rotating disk 301 is fixedly installed on the output shaft of the motor 3. The rotation of the motor 3 can make the rotating disk 301 rotate. A connecting rod 302 is rotatably installed on the side of the rotating disk 301. The rotation of the rotating disk 301 can make the connecting rod 302 move, and the connecting rod 302 moves the rotating disk 301. The circular motion of the connecting rod 302 is converted into the linear motion of the rack 303. The end of the connecting rod 302 is rotatably connected to the rack 303. The movement of the connecting rod 302 can make the rack 303 move. Since the connection point between the connecting rod 302 and the rotating disk 301 is not at the center of the rotating disk 301, the connecting rod 302 will periodically move left and right, and the rack 303 will periodically move left and right. The rack 303 is meshed with the gear 202, and the rack 303 makes a linear motion, which makes the gear 202 make a circular motion, and the rotating cylinder 202 As the rack 303 periodically moves left and right, the gear 202 periodically makes a circular motion. The gear 202 rotates alternately in the clockwise direction and the counterclockwise direction.

A feed port 102 is fixedly installed in the middle of the upper cover 101, and the tea leaves before processing enter from the feed port 102. A notch is provided above the rotating cylinder 2, and the feed port 102 is above the notch. The tea leaves can just enter from the notch, and when the rotating cylinder 2 rotates, the rotation angle is smaller than the angle of the notch, and the tea leaves put into the feed port 102 can all fall into the rotating cylinder 2.

[0023] A discharge port 103 is fixedly installed on the front side of the box body 1 , and the discharge port 103 cooperates with the front side of the rotating drum 2 . The processed tea leaves fall from the discharge port 103 and are collected.

[0024] Among them, the upper part of the rear side plate of the box body 1 is inclined forward, and the angle between the rear side plate and the lower side plate is an acute angle, but close to ninety degrees. The rotating cylinder 2 is also inclined relative to the lower side plate, and the front side of the rotating cylinder 2 is slightly lower. When the rotating cylinder 2 rotates, the tea leaves will gradually move forward and finally fall from the discharge port 103.

[0025] The surface of the rotating drum 2 is provided with through holes, the size of which is larger than the size of the broken materials and smaller than the size of the tea leaves. When the rotating drum 2 rotates, the broken materials are screened out from the through holes, and the tea leaves continue to move.
