Next, a method for forming the planting groove 60 and the soil puddle 62 in the bottom portion 61 of the planting groove 60 by the above-described planting groove forming apparatus 1 will be described with reference to FIGS. 4-6.

As shown in FIG. 4 , the worker mounts the plurality of forming parts 10 , 10 to the attachment frame 52 of the rotary 51 of the working machine 50 via the mounting part 20 , and then travels the rotary 51 with the working machine 50 . By pulling the planting groove forming device, the claws 51a of the rotary 51 form a planting groove 60 having a predetermined depth d in the soil while plowing the soil.

At this time, as shown in FIGS. 5 and 6, the soil thrown up by the claws 51a of the rotary 51 is pushed laterally by the side plates 11, 11 of the shaping portions 10, 10, thereby forming a planting groove having a predetermined depth d. At the same time as forming the ditch 60, the tail wheels 31, 31 press down the soil accumulated in the bottom 61 of the planting ditch 60, so that an elongated belt-like puddle 62 of constant height h is formed in the center of the bottom 61 of the ditch 60. is formed.

Therefore, with the above-described planting groove forming apparatus 1, the soil thrown up by the claws 51a of the rotary 51 when plowing the field is immediately distributed to the left and right to form the planting grooves 60, and at the same time, the valley raising section 30 is used to plant. The planting groove 60 and the soil puddle 62 are formed without scraping hard soil deeper than the bottom 61 by forming a thin belt-like soil puddle 62 in the center of the bottom while compressing the soil of the bottom 61 of the trench 60.例文帳に追加It is possible to reduce the load at the time.

Further, the puddle 62 can be formed with a constant height h by firmly pressing the sides of the puddle 62 with the tail wheels 31, 31 to compact it. As a result, the seedlings can be stably planted without variation in the planting positions of the seedlings in the soil pool 62, so that the planting work can be made more efficient.

In addition, by arranging the planting groove forming device 1 near the rear of the claw 51a of the rotary 51, the overall length of the planting groove 60 can be increased, and the overall length of the work machine 50 can be shortened to improve operability. Moreover, since the planting groove forming device 1 does not accumulate plowed soil, even a working machine 50 with a relatively small traction force such as a small tractor or a riding type tiller can be used. It is possible.

Although the preferred embodiments of the present invention have been illustrated in the above embodiments, the present invention is not limited to the above embodiments, and improvements and modifications are possible within the scope of the claims. For example, the tail wheels 31, 31 of the planting ditch forming device 1 may be arranged in parallel with three or more to form a plurality of belt-shaped earth puddles.
