Example

[0031] like Figure 1-Figure 4 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0032] In order to effectively remove the lighter impurities in the corn seeds during the screening process, this embodiment provides the following design:

[0033] The outside of the screening box 1 is provided with a cleaning mechanism 5, which is arranged corresponding to the screening mechanism 1 2.

The air nozzle 2 53 is arranged on the side of the air separator box 52. Multiple groups of air nozzles 2 53 are inclined on the side of the air separator box 52. Multiple groups of air nozzles 2 53 can blow air evenly over the corn seeds passing by. The corn seeds are relatively heavy and will be settled in the air flow. Light impurities will be blown away by the air flow, so that the corn seeds can be further screened.

[0034] In this embodiment, an exhaust fan 6 is provided on the side of the screening box 1. Multiple groups of exhaust fans 6 are provided on the side of the screening box 1. The setting of the exhaust fan 6 can discharge the air inside the screening box 1 together with the lighter impurities out of the screening box 1.

[0035] The implementation principle of the second embodiment of the present invention is as follows: the air nozzle 2 53 in the impurity removal mechanism 5, under the action of the air pump 2 51, quickly sprays air into the corn seeds above the screening net 24. When the air contacts the corn seeds, since the corn seeds are relatively heavy, the corn seeds will be settled in the airflow, and the light impurities in the corn seeds will be blown away by the airflow. At this time, the exhaust fan 6 blows air outwards, and the air inside the screening box 1 will take away the light impurities in the corn seeds when it is discharged by the exhaust fan 6, which is beneficial to improve the quality of corn seed screening.
