The invention discloses a special field quantitative seed-sowing vehicle. The special field quantitative seed sowing vehicle comprises wheels, a pushing handle, a bracket, seed sowers, material storage barrels, round distribution cavities, discharging nozzles, distribution discs, distribution grooves, rotary columns, rotary gears, a motor and a motor gear. The special field quantitative seed-sowing vehicle disclosed by the invention has the beneficial effects that the special field quantitative seed-sowing vehicle can realize an automatic seed sowing function; seeds are put into the material storage barrels and then the motor is started; the motor gear drives the distribution discs to rotate; when the distribution grooves located at the outlets of the material storage barrels are rotated to the discharging nozzle, seed sowing is realized. The special field quantitative seed sowing vehicle is simple in structure and convenient to manufacture; quantitative seed sowing can be realized and manpower and material resources are saved; the special field quantitative seed-sowing vehicle is convenient to operate, the labor amount is easy to alleviate and the production efficiency is improved; the seeds can be sowed into a plurality of seed-sowing holes at the same time, so that the labor intensity is extremely improved and the work amount is reduced.
