[0018] The present invention provides a fully automatic onion sowing device for onion planting through improvement, which has the following improvements and advantages compared with the prior art:

[0019] First, the present invention is provided with a sowing mechanism, which stores green onion seeds above the interior of the sowing box. The green onion seeds can fall into the interior of the seed separation bin through the seeding port. When the driving motor is started, the driving motor causes the rotating shaft to drive the seed separation ring to rotate. The rotation of the seed separation ring can sequentially send the green onion seeds into the interior of the seed separation bin through the seeding port. The green onion seeds will move along the inclined surface inside the seed separation bin to the interior of the inoculation plate, and then fall into the interior of the sowing tube, and can be planted underground through the sowing tube. Due to the special structure of the seed separation ring, the green onion seeds fall into the interior of the seed separation bin in equal amounts, and the green onion seeds sown each time are also quantitative, thereby achieving the effect of quantitative sowing and ensuring the uniformity of sowing.

[0020] Secondly, the present invention is provided with a cleaning mechanism. When the driving motor is started to drive the seed separation ring to rotate for seed separation, the driving motor will also drive the transmission shaft to rotate through the transmission gear and the transmission belt. The transmission shaft can then drive the cleaning brush to rotate. The cleaning brush is inside the seeding bin. When the green onion seeds move inside the seeding bin, the rotation of the cleaning brush can clean the surface of the green onion seeds and sweep away the dead skin on the surface of the green onion seeds, which can improve the survival rate of the green onion seeds in the field. At the same time, the air pump is started and generates suction inside the seeding bin through the suction pipe. The dead skin swept inside the seeding bin can be collected, thereby achieving the effect of automatically cleaning the green onion seeds during sowing, thereby improving the sowing survival rate of the green onion seeds.

[0021] Third: In the present invention, after the ground-breaking roller crushes the ground, the second hydraulic rod can be started, and the second hydraulic rod drives the first mounting plate and the pressure rod to move downward. The downward movement of the pressure rod will squeeze the furrowing plow, so that the tip of the furrowing plow can be inserted into the ground obliquely downward. As the device moves, furrows can be opened on the crushed ground, achieving the effect of automatic furrowing.

[0022] Fourthly, according to the present invention, when the green onion seeds fall into the furrows opened by the furrowing plow, the third hydraulic rod is activated, and the third hydraulic rod drives the second mounting plate and the furrow leveling plate to move downward. When the furrow leveling plate contacts the ground downward, the furrow leveling plate will flip over. Through the shape of the furrow leveling plate, the soil on both sides of the furrow can be pushed into the interior of the furrow, so that the green onion seeds can be buried in the ground, thereby achieving the effect of automatic furrow leveling.
