Accordingly, since the drainage groove 33 does not move up and down during traveling on the road or when the machine is loaded on a truck or the like, the drainage groove 33, the rotating shaft 35a of the arm 35, etc. The damage of each part including can be suppressed.
[0022]
It should be noted that the draining groove device 33 and the sowing groove device 7 are in a relational position in which drainage grooves are formed substantially parallel to the side of the seeding strip after the sowing groove device 7 has passed. What is necessary is just to arrange | position and comprise, and what is necessary is just to select the context of an attachment position freely.
The direct water sowing machine 1 is provided with a fertilizer applicator 45, which is attached to a fertilizer tank 46, a feeding device 47, a fertilizer transfer pipe 48 and a float 19 provided at the rear of the traveling vehicle body 2. The fertilizer grooving device 49, the wind turbine wheel 50, and the air chamber 51 are provided in the same manner as the seeding machine. The fertilizer applicator 45 is configured to apply fertilizer to the side of the sowing to the field, and similarly to the seeding machine 3, the fertilizer 45 is applied to the field at the same time in a streak manner for eight strips.
[0023]
The seeder 3 configured in this manner is placed in a field that has been submerged after the leveling work, and the fertilizer tank 46 is filled with fertilizer, and the seed tank 4 is filled with seeds and advanced to start the seeding work. To do.
Then, as shown in FIG. 4, the seeds in the seed tank 4 reach the feeding roll 22 that rotates downward, and are supplied to the seed grooves 21 on the outer periphery of the feeding roll 22, respectively. Sent to. At that time, the seeds in the seed groove 21 reach the brush 26 on the lower rotation side, the surface is leveled and becomes a fixed amount, and the conveyance start end of the lower transfer pipe 6 is accompanied with the rotation of the feeding roll 22. Falls on the part. At that time, the air chamber 9 stores the compressed air generated by the wind turbine 8 and flows into the communicating transfer pipes 6.
[0024]
In this way, the seeds are conveyed by air in the transfer pipe 6 by the compressed air blown from the air chamber 9, reach the seeding grooving device 7 on the tip side, and are leveled by the float 19. It is squirted and sown in the field. And the soil covering board 29 keeps a predetermined angle with respect to the advancing direction, rakes the top soil, performs soil covering on the sowing groove in which the seed is sown, and completes the sowing work.
[0025]
In this way, the seeder 3 performs the sowing work on the field scene that has been flooded as the traveling vehicle body 2 moves forward. At the same time, the drainage grooving device 33 attached to the machine frame 34 is used for sowing. Advancing while forming a drainage groove in a substantially parallel manner along the side of the sowing line sowed by the groove producing device 7. In this case, the drainage grooving device 33 grooving the drainage groove while moving forward on the trace that the rear wheel 11 has passed, so the soil resistance is relatively small, and the grooving device 33 can be grooved with a small amount of horsepower. The drainage groove formed by the drainage grooving device 33 is grooved with a scissors or the like at one end to the water intake in the field and the other end to the drainage in the field so that the water can flow easily. It is important to perform post-processing so that the water can be connected and drained easily. In general, it is the minimum requirement for the paddy field to level the soil surface sufficiently evenly, but this makes it possible to quickly drain and enter the paddy field.
[0026]
And when seeding work in a paddy field with good drainage or turning the body at the edge, the grooving device raising operation lever 37 is operated so that the lower grooving device 33 is above the bottom surface of the float 19. Raise to the highest position where it will be positioned.
As described above, the drainage grooving device 33 regulates the soil pushed away by the entry portion 33a and the generated water flow laterally with respect to the traveling direction by the regulating portion 33b. When the water flows sideways, the soil reaches the sowing position and fertilization position, so that the seeding depth and fertilization depth become deep, so that the emergence is delayed and the fertilization effect is inappropriate, which adversely affects the cultivation. Can be suppressed. Moreover, it can suppress that a soil and a water flow flow to the side, the soil and water flow reach a sowing position and a fertilization position, and a seed and fertilizer are poured. In addition, when the water flow flows to the side, the water flow reaches the sowing position and fertilization position, and the covering soil by the cover plate 29 etc. is washed away, so that the seeding depth and fertilization depth become shallow, and seedling establishment at the time of cultivation becomes worse. It can suppress that a fertilization effect is not acquired.
[0027]
Further, since the drainage groove 33 is configured to protrude downward from the lower end of the entry portion 33a as the lower end of the restricting portion 33b goes to the front side, it is pushed away by the entry portion 33a toward the rear side. The generated soil and the generated water flow easily flow to the side, and the soil and water flow are smoothly discharged toward the rear side. As a result, the soil and water flow smoothly flow backward, and the soil and water flow to the left and right at the front end. It can suppress that it is washed away and can suppress having a bad influence on cultivation as mentioned above.
[0028]
Further, when the drainage groover 33 is seeded in a paddy field with good drainage, the drainage groover 33 is operated by operating the groover raising operation lever 37 so that the lower end of the drainage groover 33 is above the bottom surface of the float 19. It is possible to prevent the drainage ditch from being raised by raising it to the highest position where it is located, and to prevent the soil pushed away by the ditching of the drainage ditch and the generated water flow from adversely affecting cultivation as described above be able to. Further, when the machine body is swung on the heel, the seeding machine 3 is lifted from the field by operating the lifting lever 18, and the drainage groover 33 is floated at the lower end by operating the groove lifter operating lever 37. The drainage groove 33 is accommodated above the bottom surface of the float 19 so that the drainage groove 33 interferes with the ridge. And can be prevented from being damaged. Since the groove-raising operation lever 37 is provided close to each other on the right side, which is on the same side as the lifting lever 18 and the control seat 13, the levers 18 and 37 are moved when the aircraft is turning. Easy to operate.
[0029]
In addition, although the above-mentioned drainage grooving device 33 is configured to be lifted by the operation of the grooving device raising operation lever 37, it may be configured to be interlocked with the operation of the lifting lever 18 as shown in FIG. . In the configuration shown in FIG. 10, the lifting link 14 and the arms 35 of the right and left drainage groove 33 are connected by a wire 55. Thus, when the machine body is turned at the edge of the farm, the arm 35 is rotated upward by the operation of the lifting lever 18 so that the lower end of the drainage grooving device 33 floats. It is possible to raise the right and left drainage grooves 33 to the highest rise position that is located above the bottom surface of the 19 and prevent the drainage grooves 33 from being damaged due to interference with the ridge. it can.
