[0026] As Figures 1-5 The application discloses a kind of Lanzhou lily bulb screening devices, including rack 1, the top of rack 1 is sequentially provided with feed inlet 2, first screening zone 31, second screening zone 41, third screening zone 51 and fourth screening zone 8;The bottom side of the first screening zone 31 is arranged with first discharge outlet 3 opened in the side wall of rack 1, the bottom side of second screening zone 41 is arranged with second discharge outlet 4 opened in the side wall of rack 1, the bottom side of third screening zone 51 is arranged with third discharge outlet 5 opened in the side wall of rack 1, the bottom side of fourth screening zone 8 is arranged with fourth discharge outlet 6 opened in the side wall of rack 1;Power mechanism 7 is provided between third discharge outlet 5 and fourth discharge outlet 6 on the rack 1, screening mechanism 100 is installed on power mechanism 7, and screening mechanism 100 is arranged between first screening zone 31 and third screening zone 51;The two sides of first screening zone 31, second screening zone 41 and third screening zone 51 are respectively provided with adjusting mechanism 9.

[0027] Power mechanism 7 includes two groups of driving gears 72 arranged symmetrically, and the two groups of driving gears 72 are connected with two groups of driven gears 73 arranged at the back of the rack 1 through first chain 101 and second chain 108, respectively.

[0028] Screening mechanism 100 includes first chain 101 and second chain 108, and the first chain 101 and the second chain 108 respectively include a plurality of chain links 107 connected two by two. The chain links 107 are two by two adjacent in front and back, and the rear chain link 107 is hinged with the rear end of single lug plate 104, and the front end of single lug plate 104 is hinged on the end of lead screw 102 through a pin shaft. The front chain link 107 is hinged with the front end of double lug plate 105, and the rear end of double lug plate 105 is hinged with the front end of single lug plate 104 and is hinged on the lead screw 102 at the same time. The rear end of double lug plate 105 is hinged with the lead screw 102, and is also connected with first rolling wheel 103. The front end of double lug plate 105 is hinged with chain link 107, and is also connected with second rolling wheel 106.

[0029] Adjusting mechanism 9 includes first adjusting plate 92, second adjusting plate 93, third adjusting plate 94 and adjusting screw 91, and is arranged symmetrically along the two sides of the rack 1. The bottom of adjusting screw 91 is inserted into the position above limiting plate 11 arranged on the rack 1 and located on first chain 101 and second chain 108 respectively, and pressure plate 12 is arranged between adjusting screw 91 and limiting plate 11. First rolling wheel 103 is installed on first adjusting plate 92, second adjusting plate 93 and third adjusting plate 94 respectively, and rotates around its own axis while rotating with driving gear 72 to drive first rolling wheel 103 to roll through first adjusting plate 92, second adjusting plate 93 and third adjusting plate 94 in turn and drive lead screw 102 to move horizontally. Second rolling wheel 106 is limited by limiting plate 11 on the rack 1.

[0030] The working process of this utility model is as follows:

[0031] like Figures 1-5 As shown, the distance between the lead screws 102 is first adjusted by adjusting the adjusting screws 91 located in the first-level screening zone 31, the second-level screening zone 41, and the third-level screening zone 51 respectively. The distance increases sequentially from the first-level screening zone 31, the second-level screening zone 41, and the third-level screening zone 51 to determine the size of the Lanzhou lily bulbs screened in the first-level screening zone 31, the second-level screening zone 41, and the third-level screening zone 51.

[0032] Then, the Lanzhou lily bulbs are poured in through the feed inlet 2. As the screening mechanism 100 moves in parallel, the Lanzhou lily bulbs are conveyed from the first screening zone 31, the second screening zone 41, the third screening zone 51, and all the way to the fourth screening zone 8. When the diameter of the Lanzhou lily bulb is smaller than the set diameter of the screening zone, the Lanzhou lily bulb will fall off the screening mechanism 100 and be output from the corresponding discharge port.

[0033] When the diameter of the Lanzhou lily bulb is larger than all the set screening diameters, it is output from the fourth discharge port 8 through the conveying of the screening mechanism 100.

[0034] Through the above screening process, Lanzhou lily bulbs will be sorted by size, with large, medium, and small commercial bulbs entering the market for sale, while the original seed stock will be used as seed resources for field planting.

[0035] This invention employs a lead screw for graded screening. The natural spacing between adjacent lead screws is several chain links. The chain is limited by a second rolling wheel on a limiting plate, and the lead screw is limited by an adjusting plate via a first rolling wheel. The distance between the adjusting plate and the limiting plate is adjusted by a specially designed adjusting device to achieve stepless adjustment of the lead screw spacing. This enables on-demand screening of Lanzhou lily bulbs without being limited by mechanical structure, resulting in a high degree of automation. During the screening process, the lead screw can not only move forward parallel to the ground but also rotate around its own axis, facilitating the transport and protection of Lanzhou lily bulbs and making it highly practical.

[0036] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, based on the technical teachings provided by this utility model and as common knowledge in the mechanical field, other equivalent modifications and improvements can be made, and these should also be considered within the scope of protection of this utility model.
