Specifically, a containing cavity is defined in the shell 10, a feed inlet 11 communicated with the containing cavity is formed in the upper end of the shell 10, and a discharge through hole 12 communicated with the containing cavity is formed in the lower end of the shell 10; the pump body 20 is arranged on the shell 10 and connected with the containing cavity, and the pump body 20 can suck air flow from the middle lower end of the containing cavity and convey the air flow to the feeding hole 11; the grading component 30 is arranged in the accommodating cavity along the vertical direction, a spiral turntable 32 extending along the vertical direction is arranged on the grading component 30, and the upper end of the turntable 32 is communicated with the feed port 11 so that seeds to be dried are conveyed to the turntable 32 from the feed port 11; the receiving assembly 40 is disposed in the accommodating cavity and located below the grading assembly 30, the receiving assembly 40 is provided with a receiving groove, a plurality of areas are sequentially disposed on the receiving groove from inside to outside to receive seeds with different drying degrees separated from the rotating disc 32 due to centrifugal force, and at least one part of the discharging through hole 12 is communicated with the receiving groove.

In other words, the seed drying device 100 according to the embodiment of the present invention is mainly composed of a housing 10, a pump body 20, a classifying assembly 30 and a receiving assembly 40, wherein a receiving cavity is provided inside the housing 10, an inlet 11 and an outlet 12 communicating with the receiving cavity are respectively provided at an upper end and a lower end of the housing 10, the pump body 20 is provided on an outer surface of the housing 10, and the pump body 20 can suck an air flow into the receiving cavity through the outlet 12 and convey the air flow into the inlet 11. Inside the containing cavity, a grading component 30 is also vertically arranged, and the grading component 30 comprises a spiral rotary disc 32.

When a large amount of seeds are dried, firstly, the seeds to be dried are fed from the feed inlet 11 to the rotary table 32, the seeds rotate along the spiral rotary table 32 under the action of air flow and self weight, and are separated from the rotary table 32 under the action of centrifugal force after rotating to a certain speed. The seeds to be dried have different weights due to their different water contents, and thus different falling areas. Subsequently, the seeds falling to different areas can be received, that is, the seeds with different drying degrees can be collected, respectively, by the receiving grooves provided at different areas in the receiving assembly 40 disposed below the grading assembly 30. It should be noted that, because the pump body 20 is communicated with the discharge through hole 12 and the feed inlet 11, the seeds which reach the designated area and do not reach the drying requirement are continuously sucked by the pump body 20 and conveyed to the inside of the accommodating cavity for repeated drying until the drying is completed.

Thus, according to the seed drying device 100 of the embodiment of the present invention, the seeds to be dried are conveyed to the grading component 30 inside the accommodating cavity through the feed inlet 11, and are subjected to spin drying along the turntable 32 of the grading component 30 by applying high-speed airflow and under the action of the weight of the seeds, and after the seeds are rotated to have a certain speed, the seeds with different drying degrees are separated from the turntable and are subjected to grading collection by the receiving component 40. This seed drying device 100 can solve the not good problem of drying effect that exists among the current seed drying device, and the degree of difficulty of the different dry degree seeds of manual screening has been simplified in the seed classification of the different dry degree of rotation realization through seed self simultaneously.
