Detailed Implementation
[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0023] Example 1, such as Figures 1-6 As shown, a multi-layer tea screening device includes a screening box 1, a tea conveying structure on the top of the screening box 1, and a multi-layer tea screening structure inside the screening box 1.
[0024] Specifically, the multi-layer tea screening structure includes two upper and lower C-shaped frames 2 rotatably installed inside the screening box 1. Multiple connecting springs 3 are fixedly installed on the inner sides of both upper and lower C-shaped frames 2. These connecting springs 3 are divided into upper and lower groups, and protective frames 4 are fixedly installed on the inner sides of both groups of connecting springs 3. A first screen 5 is fixedly installed on the inner side of the upper protective frame 4, and a second screen 6 is fixedly installed on the inner side of the lower protective frame 4. Vibration motors 7 are fixedly installed at the bottom of both the first and second screens 5 and 6. A first flip motor 8, whose output end is connected to the upper C-shaped frame 2, and a second flip motor 9, whose output end is connected to the lower C-shaped frame 2, are fixedly installed on the surface of the screening box 1.
[0025] In use, multiple connecting springs 3 restrict the No. 1 screen 5 and No. 2 screen 6 inside the upper and lower protective frames 4 to sway inside the upper and lower C-shaped frames 2. At this time, the upper and lower protective frames 4 protect the outside of the No. 1 screen 5 and No. 2 screen 6 respectively, with the purpose of concentrating the tea leaves on the top surface of the No. 1 screen 5 and No. 2 screen 6. After the tea conveying structure transports the tea leaves into the screening box 1, the two vibrating motors 7 start operating. The vibrations generated by the two motors 7 cause the first screen 5 and the second screen 6 to vibrate. The tea leaves fall from the top of the screening box 1 onto the top surface of the first screen 5. With the vibration of the first screen 5, the tea leaves undergo their first screening. Smaller tea leaves and impurities pass through the holes of the first screen 5 and fall onto the top surface of the second screen 6. With the vibration of the second screen 6, the tea leaves undergo a second screening. At this point, fine tea leaves and impurities are sieved out through the holes of the second screen 6. After the tea leaves are screened, the second rotating motor 9 drives the second screen 6 inside the lower U-shaped frame 2 to rotate 90° clockwise, and the first rotating motor 8 drives the first screen 5 inside the upper U-shaped frame 2 to rotate 90° counterclockwise. At this point, both the first screen 5 and the second screen 6 are facing the ground. Figure 4 As shown, the two vibrating motors 7 continue to operate, which can shake off the impurities clogging the holes of screen 5 and screen 6. After the impurities are shaken off, the first flipping motor 8 drives the upper C-shaped frame 2 to rotate 90° clockwise, which can reset screen 5. After screen 5 is reset, the second flipping motor 9 drives the lower C-shaped frame 2 to rotate 90° counterclockwise, which can reset screen 6. Figure 3 As shown.
[0026] Example 2, as Figures 1-5 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:
[0027] The tea conveying structure includes a tea inlet frame 10 fixedly installed on the top of the screening box 1, a tea storage box 11 fixedly installed on the top of the tea inlet frame 10, the screening box 1, the tea inlet frame 10 and the tea storage box 11 are connected in a continuous manner, a feeding motor 12 is fixedly installed on the surface of the tea inlet frame 10, a rotating shaft 13 that passes through the interior of the tea inlet frame 10 is fixedly installed at the output end of the feeding motor 12, the rotating shaft 13 is rotatably installed at the connection between the tea storage box 11 and the tea inlet frame 10, and three material picking plates 14 are fixedly installed on the outside of the rotating shaft 13.
[0028] With this setup, unscreened tea leaves can be directly fed into the tea storage box 11. At this time, the feeding motor 12 drives the three picking plates 14 outside the rotating shaft 13 to rotate, which can bring the tea leaves inside the tea storage box 11 into the tea inlet frame 10. The tea leaves entering the tea inlet frame 10 can then fall directly into the screening box 1. The tea conveying structure makes it easy to control the flow rate of tea leaves entering the screening box 1, thereby improving the screening efficiency of the device.
[0029] Example 3, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:
[0030] The screening box 1 has a first discharge hopper 15 that extends to its right side and is located at the bottom of the upper chamfered frame 2. The screening box 1 also has a second discharge hopper 16 that extends to its left side and is located at the bottom of the lower chamfered frame 2.
[0031] With this setup, the tea leaves vibrating through the No. 1 screen 5 inside the upper C-shaped frame 2 fall into the No. 1 discharge hopper 15 and are guided to the outside, while the tea leaves vibrating through the No. 2 screen 6 inside the lower C-shaped frame 2 fall into the No. 2 discharge hopper 16 and are discharged to the outside.
[0032] Example 4, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:
[0033] A collection box 17 is slidably mounted on the surface of the screening box 1, extending into its interior. The collection box 17 is located at one end near the bottom of the screening box 1.
[0034] With this setup, the collection box 17 is used to hold the impurities that fall from the No. 1 screen 5 and the No. 2 screen 6. The impurities can be processed by removing the collection box 17 from the inside of the screening box 1.
[0035] Example 5, as Figures 1-4 Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:
[0036] The tea inlet frame 10 is located above the first screen 5 and near the left end.
[0037] This design ensures that the tea leaves falling from inside the tea inlet frame 10 can accurately land on the top surface of the first sieve 5.
[0038] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
