Description

Technical Field

[0001] The utility model relates to an agricultural corn seed screening device, in particular to an agricultural corn seed screening device. Background Art

[0002] "Food is the most important thing for people, and seeds are the first priority for food." Seeds are the basic means of production in agricultural production. They play an irreplaceable role in agricultural production and are the foundation of agricultural development. A good seed can promote crop yields, increase farmers' incomes, and effectively ensure food security. Similarly, inferior seeds can also cause reduced production or even total crop failure. Although agricultural production increases depend on the combined effects of various factors, seeds, as the most important internal factor, play a key role. If the seeds are not good, even with various supporting production measures, production cannot be increased. The role of seeds in agricultural production is basic, internal, irreplaceable, and decisive.

[0003] When screening seeds, the existing device can only perform simple screening on the seeds, and additional cleaning work is required after screening, and the overall operation is relatively cumbersome.

[0004] When the existing device is used, the seeds need to be screened at multiple levels to make the screening results more accurate. At the same time, the cleaning work is completed for the device while screening. As shown in the publication number CN215542765U, a large number of corn seeds can be effectively cleaned and screened by setting a rolling mechanism and a wind selection device. By setting a rolling mechanism, when the seeds enter the separation box, the motor is started to drive the rotating shaft to start rotating, and the hollow sleeve rotates with the rotating rod. When the seeds come into contact with the hollow sleeve, the full seeds are directly collided and screened out and escape through the second discharge port, while the shriveled seeds enter the hollow sleeve and are stirred by the stirring blades to separate the dust on the surface of the seeds. The seeds are then discharged through the small grooves opened at the bottom of the separation box, which plays a role in seed screening. The dust and corn stems in the separation box are connected through the exhaust pipe, so that they are sucked out by the wind selection device, which plays a cleaning role. However, the above device cannot complete the cleaning work at the same time when performing screening work, and the seeds are separated from the dust only by the stirring blades, and the separation is not comprehensive enough.

[0005] Therefore, those skilled in the art have proposed an agricultural corn seed screening device to solve the problems raised by the background technology. Utility Model Content
