[0029] The driving assembly 3 includes two transmission gears 301, a support shaft 302, a motor 303 and a support frame 304.

The two ends of several springs 403 are respectively fixedly connected to the inner wall of the pushing plate 202 and one end of the brush plate 402;

[0031] The stirring mechanism 2 further includes several heating wires 5. Several heating wires 5 are uniformly and fixedly connected to the inner walls of several pushing plates 202, and several pushing plates 202 are made of heat-conducting metal copper;

[0032] In this embodiment, first, black tea leaves are loaded into the provided electric baking oven 1. The electric baking oven 1 is powered on and started to bake and kill the tea leaves inside at a high temperature. At the same time, the motor 303 supported and fixed by the support frame 304 is started to provide a force to drive one of the transmission gears 301 connected thereto to rotate under force. By the rotation of one of the transmission gears 301, the other transmission gear 301 engaged therewith is driven to rotate. By the rotation of the other transmission gear 301, the support shaft 302 is driven to rotate. By the rotation of the support shaft 302, the turntable 201 can be driven to rotate inside the electric baking oven 1 under force. By the rotation of the turntable 201, several pushing plates 202 can be driven to rotate.

Moreover, the provided heating wires 5 are powered on to generate heat. By the heat generated by the heating wires 5, the heat is conducted to the black tea leaves in contact therewith through the pushing plates 202 made of heat-conducting metal copper for further baking. Thus, it is convenient to rotate and turn over the piled tea leaves to make them evenly dispersed, and at the same time, the tea leaves are further heated and baked, effectively improving the efficiency of baking and killing the green.

[0033] Further, the filtering mechanism 6 includes two filter mesh plates 601 and two handles 602. One end of the two filter mesh plates 601 is installed on the inner bottom of the electric baking oven 1 through a plurality of revolving components 7, and the two handles 602 are respectively fixedly connected to the bottoms of the two filter mesh plates 601;

[0034] The revolving component 7 includes a rotating shaft 701, a rotating block 702 and a torsion spring 703. Both ends of the rotating shaft 701 are fixedly connected to the inner bottom of the electric baking oven 1.

[0035] On the basis of the above embodiment, it is supported by the provided rotating shaft 701, and the provided torsion spring 703 provides a force to make the rotating block 702 rotate on the side wall of the rotating shaft 701. The rotation of the rotating block 702 drives the connected filter mesh plate 601 to rotate accordingly. The two filter mesh plates 601 rotate and close to block the bottom of the electric baking oven 1. At this time, the tea leaves after overturning and baking can be filtered and separated from the impurities through the provided filter mesh plate 601, and the provided brush plate 402 rotates in contact with the filter mesh plate 601 to clean and scrape off the tea leaves attached to the filter mesh plate 601 to avoid affecting the filtration. After the baking and withering is completed, the filter mesh plate 601 can be driven to rotate and open by pulling down the provided handle 602. By rotating and opening the filter mesh plate 601, the withered tea leaves can be discharged from the bottom of the electric baking oven 1, thus achieving the effect of facilitating the automatic filtration and separation of impurities in the tea leaves.

[0036] The implementation principle of a greening device for black tea in an embodiment of this application is as follows: When in use, first, load black tea leaves into the electric baking oven 1. The electric baking oven 1 is powered on and started to bake and green the tea leaves inside at a high temperature. At the same time, the motor 303 supported and fixed by the support frame 304 is started to provide a force to drive one of the transmission gears 301 connected thereto to rotate under force. Through the rotation of one of the transmission gears 301, another transmission gear 301 meshing with it is driven to rotate accordingly. Through the rotation of the other transmission gear 301, the support shaft 302 is driven to rotate. Through the rotation of the support shaft 302, the turntable 201 can be driven to rotate inside the electric baking oven 1 under force. Through the rotation of the turntable 201, a number of pushing plates 202 can be driven to rotate. At this time, the spring 403 provides a force to make the brush plate 402 slide out of the telescopic groove 401 under force. Through the extension of the brush plate 402, it fits with the inner wall of the electric baking oven 1. At this time, through the rotation of the pushing plate 202, the brush plate 402 can be driven to rotate to push and clean the tea leaves in the electric baking oven 1 rotationally, so that the tea leaves move to the upper part following the rotation of the pushing plate 202 and then slide down from the upper part and fall and disperse. And, the heating wire 5 is energized to generate heat. Through the heat generated by the heating wire 5, the pushing plate 202 made of heat-conducting metal copper conducts the heat to the black tea leaves in contact with it for further baking, so as to effectively facilitate the rotation and turning of the piled-up tea leaves to make them evenly dispersed and further heat and bake the tea leaves at the same time, effectively improving the baking and greening efficiency. Secondly, it is supported by the rotating shaft 701, and the torsion spring 703 provides a force to make the rotating block 702 rotate on the side wall of the rotating shaft 701 under force. Through the rotation of the rotating block 702, the filter screen plate 601 connected thereto is driven to rotate accordingly. Through the rotation and closing of the two filter screen plates 601, the bottom of the electric baking oven 1 is blocked. At this time, the tea leaves after turning and baking can be filtered and separated from the impurities through the filter screen plate 601, and the brush plate 402 rotates in contact with the filter screen plate 601 to clean and scrape off the tea leaves attached to the filter screen plate 601 to avoid affecting the filtration. After the baking and greening is completed, the filter screen plate 601 can be driven to rotate and open by pulling down the handle 602. Through the rotation and opening of the filter screen plate 601, the tea leaves after greening can be discharged from the bottom of the electric baking oven 1, so as to effectively facilitate the automatic filtration and separation of impurities in the tea leaves.
