[0062] The first motor 4 drives the driving gear 401 to rotate, and the driving gear 401 rotates to drive the driven gear ring 302 and the rotary drum 3 to rotate. When the first motor 4 is kept at a certain power, the rotary drum 3 rotates at a constant speed, and the seed holes 301 on the rotary drum 3 are periodically connected with the seed outlet 201 in turn. When the seed outlet 201 is connected with the seed holes 301, the soybean seeds in the seed outlet 201 fall into the seed holes 301, and then fall into the lower seed tube 102. When the first motor 4 rotates at a constant speed, the cycle of the seed outlet 201 and the seed holes 301 being connected is constant, that is, the time interval of the soybean seeds falling from the lower seed tube 102 is the same. At this time, controlling the forward speed of the agricultural tractor can control the planting spacing of soybean seeds in each hole in the same row, and the spacing is controlled at 10 to 12 cm.

[0063] As the device moves, the soil covering plate 8 pushes the soil on both sides of the planting ditch into the planting ditch to bury the soybean seeds.
