[0006] One set of the wrapping rods has a first fixing frame attached to its outer surface, and there are two first fixing frames. The other set of the wrapping rods has a second fixing frame attached to its outer surface, and there are two second fixing frames. A first screening mesh is fixedly connected to the inner side of the first fixing frame, and a second screening mesh is fixedly connected to the inner side of the second fixing frame on the other side.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Reference Figures 1-4A screening device for layered collection of tea leaves in tea processing includes a screening shell 1 and a cover 2. The cover 2 is bolted to the top of the screening shell 1. The screening shell 1 provides fixing points for the cover 2, triangular locking bolt 4, motor 13, output pipe 15, temperature controller 17 and electric heating tube 18, which are fixedly connected to its outer surface and interior. At the same time, it provides output space for the tea leaves on the top of the first screening screen 10 and the second screening screen 11 through another feed port on its back. The cover 2 is bolted to the top of the screening shell 1 and provides fixing points for the feed hopper 3, which is fixedly connected to its top. It also provides a cover for the top of the screening shell 1. The feed hopper 3 is connected through the top of the cover 2 and provides space for the user to transport the tea leaves into the interior of the screening shell 1.A set of wrapping rods 6 has a first fixing frame 8 wrapped around its outer surface. The first fixing frame 8 is fixed by a triangular locking bolt 4, an extension rod 5, and the wrapping rod 6, and also provides a fixing point for the first screening mesh 10 fixedly connected to its inner side, as well as a fixing point for the pull handle 12 fixedly connected to its top. There are two first fixing frames 8. Another set of wrapping rods 6 has a second fixing frame 9 wrapped around its outer surface. The second fixing frame 9 is fixed by a triangular locking bolt 4, an extension rod 5, and the wrapping rod 6, and also provides a fixing point for the pull handle 12 fixedly connected to its inner side. The second screening mesh 11 provides a fixing point and also provides a fixing point for the pull handle 12 fixedly connected to its top. Two second fixing frames 9 are provided. The first screening mesh 10 is fixedly connected to the inner side of the first fixing frame 8. Driven by the transmission plate 14, the first screening mesh 10 intercepts larger tea leaves through its openings. On the other side, the second screening mesh 11 is fixedly connected to the inner side of the second fixing frame 9. Driven by the transmission plate 14, the second screening mesh 11 intercepts smaller tea leaves through its openings. An electric motor is fixedly connected to the bottom of the screening shell 1. When it is necessary to improve the tea screening efficiency, the motor 13 can transmit electrical energy to the inside of the motor 13 via an external control component. At this time, the motor 13 transmits rotational power to the inside of the transmission plate 14 through electromagnetic effect, and the output end of the motor 13 extends into the inside of the screening shell 1. The output end of the motor 13 is bolted to the transmission plate 14. The transmission plate 14 rotates under the drive of the motor 13, causing the tea leaves to fully contact the tops of the first screening screen 10 and the second screening screen 11, thereby improving the tea screening effect. There are three transmission plates 14, and the bottom of the screening shell 1 extends through... An output pipe 15 is connected to the bottom of the screening shell 1, providing a fixing point for a manual throttle valve 16 that is connected to its outer surface. When the output pipe 15 is open, the smallest tea leaves are conveyed to the interior of the external receiving component under the action of gravity, thus completing the output of the tea leaves. The output pipe 15 is located outside the motor 13, and the manual throttle valve 16 is connected to its outer surface. When it is necessary to output the smallest tea leaves after screening, the manual throttle valve 16 can be rotated by external force. At this time, the manual throttle valve 16 opens, driving the internal connection of the output pipe 15.

[0022] Reference Figures 2-3A triangular locking bolt 4 is fitted into the inner side of the screening shell 1. Driven by the extension rod 5, the bolt 4 is inserted into the inner side of the screening shell 1, thus fixing the first fixing frame 8 and the second fixing frame 9. Simultaneously, when it is necessary to disassemble the first fixing frame 8 and the second fixing frame 9, external force can be used to pull the first fixing frame 8 and the second fixing frame 9, driving the triangular locking bolt 4 to disengage from the screening shell 1. An extension rod 5 is fixedly connected to the inner side of the triangular locking bolt 4. Driven by the elastic potential energy of the spring 7, the extension rod 5 causes the triangular locking bolt 4, fixedly connected to its tail end, to extend outward. An extension rod 5 is fixedly connected to the inner side of... The wrapping rod 6 is fixedly connected to the inside of the extension rod 5, providing a fixing point for the spring 7 fixedly connected inside it. The spring 7 is fixedly connected inside the wrapping rod 6. Under the action of elastic potential energy, the spring 7 generates a pushing force on the extension rod 5, which drives the triangular interlocking bolt 4 to insert into the interior of the outer screening shell 1. The tail end of the spring 7 is fixedly connected to the interior of the extension rod 5. The top of the first fixed frame 8 and the second fixed frame 9 are both fixedly connected to the top of the first fixed frame 8 and the second fixed frame 9, providing a force point for the user to move the first fixed frame 8 and the second fixed frame 9 upward by external force.

[0023] Reference Figures 1-3 A temperature controller 17 is fixedly connected to the front of the screening shell 1. The temperature controller 17 detects the temperature data inside the screening shell 1. When it is necessary to dry the inside of the screening shell 1, electrical energy can be transmitted to the inside of the temperature controller 17 through an external control component. At this time, the temperature controller 17 transmits electrical energy to the inside of the heating tube 18. The heating tube 18 is arranged inside the inner wall of the screening shell 1. When electrical energy is transmitted to the inside of the heating tube 18 through the temperature controller 17, the resistance wire inside the heating tube 18 continuously transmits heat to the inside of the screening shell 1 through the electrothermal effect, evaporating the water vapor inside the screening shell 1 for subsequent tea screening.

[0024] The functional principle of this utility model can be explained through the following operation: First, the temperature control range of the temperature controller 17 is set by external force. At this time, the temperature controller 17 transmits electrical energy to the interior of the heating element 18. The resistance wire inside the heating element 18 continuously transmits heat to the interior of the screening shell 1 through the electrothermal effect, evaporating the moisture inside the screening shell 1 and preventing the tea leaves inside the screening shell 1 from becoming too damp. Then, the electrical energy is transmitted to the interior of the motor 13 through an external control component. At this time, the motor 13 transmits rotational power to the interior of the transmission plate 14 through the electromagnetic effect. The transmission plate 14 rotates under the drive of the motor 13. The movement causes the tea leaves to fully contact the tops of the first screening mesh 10 and the second screening mesh 11. At the same time, the first screening mesh 10 intercepts larger tea leaves, and the holes in the second screening mesh 11 intercept smaller tea leaves, thus completing the sieving of the tea leaves. After sieving, the baffle plate of the feed inlet is moved upward by external force to complete the initial discharge of the tea leaves. Then, the manual throttle valve 16 is turned by external force. At this time, the manual throttle valve 16 opens the internal connection of the drive output pipe 15. When the output pipe 15 is connected, the smallest tea leaves are transported to the interior of the external receiving component under the action of gravity, thus completing the output of the tea leaves.
