PURPOSE:To carry out the sowing work simultaneously with the fertilizing work by mixing seeds such as rice seeds with a specific amount of an agrichemical and applying the mixture to the sowing grooves. CONSTITUTION:The objective direct sowing machine is provided with a groove- opening tine wheel 15 rotating in the direction opposite to the moving direction of the machine, a soil guiding cover 16 placed above the tine wheel, a seed- dropping cylinder 28 having an opening at the back of the tine wheel 15, an agrichemical delivery pipe 31 opened in the middle of the seed-dropping cylinder 28 and a fertilizer scattering pipe 25 opened in front of the tine wheel 16. The seed delivery apparatus 26 is interlocked with the chemical delivery apparatus 30 and a mixture of the chemical and seed mixed at a definite ratio is dropped into a sowing groove through the seed-dropping cylinder 28. The tine wheel 15 forms the sowing groove and, at the same time, scatters the soil backward to cover the seeds in the sowing groove with soil mixed with a fertilizer. |
