[0033] As shown in Figure 1 The present application provides a tobacco classification and screening device, which is provided with a screening assembly for screening tobacco of different specifications, thereby improving the screening capacity of the tobacco. The present application provides tobacco to different screening assemblies through a unified material guiding assembly, thereby reducing the occupied space of the device. In addition, the present application is provided with a recycling assembly for unqualified tobacco, thereby realizing the unified recycling of unqualified tobacco.

[0034] As shown in Figure 1 and 3 The sorting assembly 4 includes a sorting disc 401, which is fixedly connected to the adjacent device or base. The sorting disc 401 is provided with at least two sorting grooves 402. The number of screening assemblies 7 is the same as the number of sorting grooves 402. Each screening assembly 7 is located below the corresponding sorting groove 402. Different screening assemblies 7 are used to screen tobacco of different specifications.

[0035] As shown in Figure 1As shown, the material guiding assembly 2 comprises a first material guiding hopper 201, a material guiding pipe 203 communicating with the lower end of the first material guiding hopper 201, and a first driving member 202.

The lower end of the material guiding pipe 203 is located above the sorting disc 401, and the first driving member 202 drives the material guiding pipe 203 to rotate, so that the lower end of the material guiding pipe 203 moves between different sorting grooves 402.

[0036] As an embodiment, the first material guiding hopper 201 is fixed by the hoisting frame 1.

[0037] As an embodiment, the first driving member 202 is a hollow electric shaft seat, which drives the material guiding pipe 203 to rotate, so that the lower end of the material guiding pipe 203 performs a circular motion around the central axis of the upper portion of the material guiding pipe 203 to move between different sorting grooves.

[0038] The material controlling assembly 3 is used to control the tobacco material delivered by the material guiding pipe 203 to the sorting grooves 402.

[0039] As an embodiment, as shown in Figure 1 and 2 , the material controlling assembly 3 comprises a fixing frame 301 and a second driving member 303, the fixing frame 301 is arranged horizontally and fixed on the material guiding pipe 203, and the body of the second driving member 303 is fixed on the fixing frame 301 by a vertical fixing plate 302. The side wall of the material guiding pipe 203 is provided with a through hole. When the telescopic portion of the second driving member 303 is inserted into the through hole, the tobacco material in the material guiding pipe 203 is blocked and prevented from moving downward. When the telescopic portion of the second driving member 303 is retracted, the tobacco material in the material guiding pipe 203 can enter the sorting grooves 402 from the material guiding pipe 203, and then be guided into the screening assembly 7 for screening.

[0040] Generally, the telescopic portion of the second driving member is extended to block the tobacco material in the material guiding pipe 203 from moving downward.

[0047] As an embodiment, the third driving member 703 is a vibration motor.

[0048] When the third driving member 703 operates, it drives the filtering cylinder 704 and the second material guide hopper 705 to vibrate, so as to vibrate and screen the tobacco introduced into the filtering cylinder 704 through the second material guide hopper 705, the qualified tobacco is guided out through the lower end of the filtering cylinder 704, and the unqualified tobacco is retained in the filtering cylinder 704 and the second material guide hopper 705 above the internal filter screen.

[0049] Preferably, the screening assembly 5 further comprises a recycling assembly 6 for unified recycling of unqualified tobacco. The recycling assembly 6 comprises a negative pressure generator 603, a recycling pipe 604 with the same number as the sorting groove 402 and the above-mentioned fixing seat 601.
