[0037] Based on the structure of the above setting, the double linkage type seed processing unit is composed of a rack 100, a box body 200, a linkage mechanism 300, a first belt conveyor 230, a second belt conveyor 240, a roller group 250, a discharge hopper 260 and a blocking plate 270, wherein the rack 100 provides structural support for the erection of the box body 200, and the box body 200 provides a processing environment for the air separation and drying of the seeds. Specifically, during the working process, the seeds enter the box body 200 from the feed inlet 210 at the top of the box body 200, and then fall on the first belt conveyor 230. The first belt conveyor 230 conveys the seeds to the inside of the box body 200, preparing for the subsequent air separation process. The air separation assembly 310 in the linkage mechanism 300 starts to work, and the centrifugal fan 3110 is started to generate wind force. The wind force is guided to the flat flared nozzle 3140 through the guide pipe 3130. The flat flared nozzle 3140 blows the wind force at a specific angle and range to the seeds output by the first belt conveyor 230. Due to the difference in aerodynamic characteristics between the seeds and impurities, the light seeds are blown upward under the action of the wind force, while the heavy impurities (such as straw, soil clumps, etc.) directly fall into the discharge hopper 260 between the output end of the first belt conveyor 230 and the roller group 250, and are discharged outside the box body 200. The seeds that have completed air separation are scattered on the second belt conveyor 240 under the action of the roller group 250 or the blocking plate 270. At the same time, the drying assembly 320 in the linkage mechanism 300 is also working. Part of the wind force generated by the centrifugal fan 3110 is guided to the air baffle 3210 through the connecting pipe 330, and forms hot air after passing through the heating plate 3220. The hot air blows to the seeds on the second belt conveyor 240 under the guidance of the blocking plate 270, and dries the seeds. The seeds that have completed drying continue to move with the second belt conveyor 240, and finally are discharged from the discharge outlet 220 at the left bottom of the box body 200, thereby completing the entire seed processing process. The double linkage type seed processing unit, by setting the linkage mechanism 300, can integrate the air separation assembly 310 and the drying assembly 320 in the box body 200, and realize linkage of the two through the connecting pipe 330, while cooperating with the layout of the first belt conveyor 230, the roller group 250 and the second belt conveyor 240 in the box body 200, so that the seeds can complete the air separation and drying processes in the box body 200. This avoids the transfer of seeds between different equipment, reduces the pollution and loss risk of seeds during the transfer process, reduces the labor cost investment, greatly shortens the overall time span of seed processing, significantly improves the seed processing efficiency, and ensures the quality of the seeds.

[0038] Further, the guide assembly 280 is arranged above the roller group 250, the guide assembly 280 comprises a wave plate 2810 with a structure of concave middle and upturned sides and four fixing columns 2820 which are vertically welded on the top surface of the wave plate 2810 and arranged in a rectangular array, the top ends of the four fixing columns 2820 penetrate the top wall of the box 200 and are threadedly assembled with locking nuts 2830.
