It is configured to do so. The extension pipe 56 in this manner, by constructing so as to put the fertilizer on the side of the fertilizer feeding casing 9, seeded feeding of the casing 6 and fertilization feeding casing 9 the same direction, be arranged in parallel to the rear edge shape Was made.

[0010] A clutch case 57 is provided above the fertilizer application case 9 and a locking lever 8 is provided on the clutch case 57. Further, a remaining amount outlet 10 is provided below the rear surface of the fertilizer application case 9 to enable removal and cleaning of the remaining amount in the fertilizer application case 9. Further, the seed dispensing case 6 arranged in series below the seed hopper 11a is also provided with a remaining amount outlet 7 at a lower rear portion. The remaining amount outlets 7 and 10 are rubber caps, which are press-fitted and can be easily removed.

[0011] The stop levers 5, 5 of the seeding / feeding case 6 are provided on the seeding / feeding drive shaft 1, and the power is cut off when the locking levers 5, 5 and the engaging pins 40, 40 are disengaged. We are in contact. A one-way clutch C1 is arranged on the seeding feed drive shaft 1 and a one-way clutch C2 is placed on the fertilizer feed drive shaft 2. The rotation of the arm is changed to intermittent rotation by the one-way clutches C1 and C2.

A drive system from the drive shaft 41 of the transmission case M to the seeding feed drive shaft 1 will be described. Drive shaft 41
Is pivoted to a link 44, the link 44 is pivoted to an intermediate arm 45, a link 46 is pivoted to the intermediate arm 45, and the link 46 is pivoted to an arm 47 and the arm 47 Are fixed to the one-way clutch C1. Further, a power transmission system from the drive shaft 41 to the one-way clutch C2 of the fertilizer feeding drive shaft 2 will be described. The arm 52 on the drive shaft 41 drives the link 51, which is connected to the intermediate arm 50,
0 is pivotally connected to a link 49, and the link 49 is pivotally connected to an arm 48 of the fertilizer feeding drive shaft 2.

The pivot 38 of the intermediate arm 45 is pivotally supported by the pivot tube 22 on the seeder frame 3, and the pivot 39 of the intermediate arm 50 is pivotally supported by the seeder frame 3. It is pivotally supported by the cylinder 23.

As shown in FIGS. 6 and 7, the seeding machine frame 3 protrudes upward from the main frame 25, and a mounting plate 20 is attached to the upper end of the seeding machine frame 3 in a state where the rear is inclined at a low angle. The seeding feeding case 6 is mounted on the mounting plate 20. The pivot tubes 22 and 23 described above are fixedly provided in the middle of the seeder frame 3, and the transmission case mounting portion 24 is located forward of the seeder frame 3.
Is protruding. Three seeding machine frames 3 are disposed on the main frame 25 in the case of six rows, and a central transmission case M is attached to the central transmission case mounting portion 24, so that power is transmitted from the PTO transmission shaft. Is transmitted. Further, the fertilizer applicator frame 4 projects rearward and upward from the main frame 25.

As shown in FIGS. 8 and 9, the fertilizer applicator frame 4
The mounting plates 16 and 17 are arranged on a frame 18 horizontally provided on the left and right. The mounting plates 16 and 17 are
The mounting plate 20 is substantially parallel to the mounting plate 20 and is arranged in a straight line. The mounting plate 20 and the mounting plate 16 are connected to each other by a connecting body 53 for reinforcement, so that the forked portion of the hopper 11 is not cracked. A float bracket 19 is provided so as to project rearward from the main frame 25, and a float bracket 28 is pivotally supported at the rear end of the float bracket 19 via a pivot shaft 29. The float F is supported so that the front can turn up and down.
