It is discharged into the grooving device 29 and the sowing grooving device 30 and fertilized and seeded in a row. Then, the fertilizer H sprinkled on the field is suppressed by the roller 40.

A technique related to the present invention will be described.
As shown in FIG. 6, it is important that the transmission rotation of the fertilizing and sowing feeding roll is transmitted by the PTO shaft which is proportional to the traveling speed of the towing vehicle 1, and the branch pipe 31,
Similarly, the distribution valve bodies 35a and 35b of 32 can be sown and fertilized in the field by making them proportional to the vehicle speed.

When the distribution device is arranged with the distribution valve body 35c just below the feeding roll 24 as shown in FIGS. 7 and 8, the branch pipe can be simplified and the structure can be simplified. Although the fertilizer storage hopper 22 and the seed paddy storage hopper 23 are integrally configured in the above-described embodiment, they may be separately configured as shown in FIG. When the seed paddy hopper 23 is removed when the machine is constructed, the fertilizer application device for rice transplanters can be diverted as it is, which is extremely convenient.

As shown in FIG. 10, a suspension frame 40 extending from the rear machine frame 17 side of the seeding and fertilizing apparatus 16 toward the upper front side is used to form the related members including the seed padding hopper 23 for sowing. Suspended frame 4 for seed paddy hopper 23 on the side
In the case where seeds are supplied by moving them while being supported by 0 and connecting them by a hook or the like, and moving them to the lower rear side as shown in the virtual diagram, the work can be simplified. The suspension means is not limited to the embodiment and may be a link mechanism.

As shown in FIG. 11, when the seed padding hopper 23 on the sowing machine side is mounted on the machine frame 17 side through the support frame 42, the sowing and fertilizing device 16 is moved up and down by the elevating link mechanism 13. The rice seed hopper storage hopper 23 is configured to move up and down between a state in which it approaches the rear side of the fertilizer storage hopper-22 in a side view and protrudes higher than the fertilizer storage hopper-22, and a lower position thereof. It is convenient to raise the seed padding hopper 23 in the hopper 23 from the control seat side so that the seed paddy hopper 23 can be supplied.

Seed padding hopper-2 on the frame of the seeder side
3 and its related transfer pipes and the like, and the fertilizer storage hopper 22 on the fertilizer application side is mounted on the vehicle body side of the towing vehicle 1, as shown in FIG. 12, the inside of the transfer pipe is fertilizer H or seed rice M. Blower 25a for pneumatically feeding air and its drive mode
Equipped with the vehicle 43 side. In this way, when the rice transplanter with the fertilizer application is attached to the towing vehicle 1, it is sufficient to simply remove the seeding device and attach the rice transplanter, and the rice transplanter and the seeder can be easily changed.

As shown in FIG. 13, the side floats 20a and 20b located at the left and right ends of the sowing and fertilizer applicator 16 and the groovers 29 and 30 and the transfer pipes mounted on the side floats 20a and 20b are integrally and upwardly moved. A bending portion (a) is provided on the frame side so that the bending portion can be set to the side, and when the working portions on both sides of the bending portion are set down to the working state, the working portion (b) is used. The plant can be moved up and down within a certain range, and at the time of work, the float follows the field surface up and down to improve soil leveling for sowing and fertilization, and when not in use, it is swung upward by a hydraulic device 44, etc. It is convenient if the structure is such that the horizontal width of the working unit can be reduced.
It should be noted that, as shown in FIGS. 14 and 15, if the sowing and fertilizing apparatuses on both the left and right sides are attached via the interchangeable part (b) so that a certain amount of swing operation can be performed on the upper and lower sides, it is possible to follow the sharp irregularities of the paddy field. . Moreover, if the sowing and fertilizing devices at both ends are swung upward to reduce the total lateral width, the number of work lines for sowing and fertilizing can be reduced, and the work on the ridge portion becomes convenient.
It is also convenient for traveling on the road or for transportation by truck.

Contrary to the previous example, as shown in FIGS. 16 and 17, in the seeding fertilizer application device 16 in which the floats are juxtaposed in the lateral direction at predetermined intervals, the floats at the left and right ends are moved up and down. If the float provided in the middle part is configured to be movable up and down within a certain range, the unevenness on the surface of the paddy field will be improved, especially The seeding depth and fertilization depth in the seeding and fertilizing section in the middle of the left and right are substantially constant based on the floats on the left and right ends, and the working accuracy is improved. In the example shown in the figure, the seeding fertilizer application device in the middle part except the left and right end sides is swingably attached via springs for vertical swing.

As shown in FIG. 18, regarding the branch pipes 31 and 32, a pipe diameter t1 obtained by branching the pipe diameter T of the non-branching portion on the base side
And t2 are smaller than the sum, that is, T <t1 + t2
And By doing so, the air resistance of the branch portion can be reduced, and the air pressure in the pipe on the branch side can be increased,
The transfer accuracy can be improved.
