Multifunctional sorghum precision sowing machine

The utility model relates to a farm instrument, and in particular relates to a multifunctional sorghum precision sowing machine. The multifunctional sorghum precision sowing machine comprises a stander (1), wherein a row of supporting power wheels are mounted at the tail of the stander (1) through a plurality of power wheel brackets (24) which are mounted side by side; the front side of each supporting power wheel (12) corresponds to a negative pressure seed disk bin (6) mounted on the stander (1); a driving gear (13) is coaxially mounted at one end part of a wheel shaft of each supporting power wheel (12) and is connected with a combined gear (15) through a transmission chain (14); and the combined gear (15) drives a sowing shaft (32) to rotate. Under mechanical traction, the sowing machine generates negative pressure through a vacuum pump; and by matching of components such as a fixed disk, a rotary seed disk and an end cover, the problem that seeds of crops cannot be sowed one by one is solved.
