[0019] Compared with the existing technology, the advantages of the air-suction quinoa precision seeding device capable of multi-grain hole sowing are:

[0020] 1. The diameter of the vertical seed storage tube is set to be able to pass only quinoa seeds through the connecting tube.

[0022] 3. When the reset airbag collides with the extrusion plate, the extruded gas in the reset airbag is blown into the seed receiving groove through the ventilation pipe, preventing the quinoa seeds from adhering to the inner wall of the hole sowing plate due to their small weight, thus ensuring that three quinoa seeds are placed in each hole.

[0023] To summarize, the present invention uses a grouped feeding mechanism to enable the three-part feeding column to pour a small portion of quinoa seeds into the vertical seed storage tube, thereby avoiding the accumulation of excessive quinoa seeds and the occurrence of blockage. The quantitative seeding mechanism can ensure that three quinoa seeds can be brought down each time the hole seeding plate is rotated. At the same time, the unblocking mechanism cooperates with the movement of the quantitative seeding mechanism to clear the end of the vertical seed storage tube, thereby avoiding the situation where two quinoa seeds are stuck at the entrance of the vertical seed storage tube.
