[0002] With the development of science and technology, precision agriculture has become the trend of future agricultural development, and precise seed throwing is an important link to achieve precision agriculture. When carrying out sowing operations, the machine has a forward speed and the speed will also change. After the seeds are thrown out, they will have a forward speed due to inertia and cannot fall vertically. It is easy to have a secondary bounce after landing, making it difficult to ensure accurate seed dropping and sowing uniformity. Accurate seed dropping is very important. Accurate seed dropping can ensure the uniform distribution of seeds in the soil, which is beneficial to the uniform growth of wheat, reduce the phenomenon of missing seedlings and ridges, and thus increase the yield per unit area. Inaccurate seed dropping is likely to affect the seedling emergence rate of seeds and then affect the crop yield. At present, most of the outlets of the seed throwing devices of seeders are vertically downward. Since the seeds have a forward horizontal initial velocity after being discharged, it is very difficult to achieve vertical falling and cannot meet the requirements of precise seed dropping at different operating speeds. The utility model adopts a design in which the direction of the seed throwing port is opposite to the operating direction of the machine, can monitor the traveling speed of the machine according to GPS, and can adjust the horizontal angle of the seed throwing port in real time by adjusting the electric push rod, change the horizontal component of the seed speed during seed throwing, and make the horizontal component of the seed speed cancel out with the traveling speed of the machine and fall vertically, so as to achieve the purpose of precise seed dropping.
