Reference numeral 90 denotes a seed supply regulator for selectively supplying seeds from the pair of seed supply barrels 40 to respective corresponding booms 30.

Looking at the operating state of the direct wave device using the blowing method according to an embodiment of the present invention according to such a configuration as follows.

When there is no seeding work, the boom 30 is bent close to the front end of the tractor 10 to be in close contact with each other, and when the seeding work is carried out again, the boom 30 is fixed to its original position and the cutting part is fixed to the tractor ( It should be straight on the side of 10).

Then, when the tractor 10 is operated, the power supply shaft of the tractor 10 operates the blower fan 50 to start supplying air uniformly to each boom 30 through the air collection distribution vessel 70. do.

At this time, since the high pressure air of the blower fan 50 is supplied to the inside of the boom 30, the seed introduced into the boom 30 flows in the boom 30 according to the air flow at the same time as the input, and then the discharge port 32 of each discharge port 32. The seed collision discharge plate 63 is guided to the seeding regulator 60 is discharged onto the fresh water surface.

In this case, when the seed inflow to the seeding regulator 60 is to be adjusted, the seed collision discharge plate 63 may be properly elevated to adjust the seed inflow.

Thus, while supplying high pressure air continuously into the boom 30 from the blowing fan 50, while the seed of the seed supply cylinder 40 is also continuously supplied into the boom 30, the seed is discharged from each of the boom 30 ( 32) midwife or harmonics on the freshwater surface is achieved.

Here, the end portion of the boom 30 is provided with a mesh netting mesh to facilitate the air ventilation.

On the other hand, when the seeding or sowing of seeds is selectively carried out, the slit hole 62a of the seeding control method 62 is released by releasing the fastening to the seeding control device 62 of the seeding controller 60. By disposing in the transverse direction or in the longitudinal direction with respect to the traveling direction of 10) it is possible to perform the midwave and harmonics.

For example, when the seed is to be sown in a midwifery manner, the seeding control mechanism 62 of the seeding regulator 60 is rotated by a predetermined angle with respect to the regulating base body 61 so that the slit hole 62a is a tractor ( 10) The seed spread is made by crossing the travel direction, that is, the shape extending in the transverse direction.

In addition, when the seed is to be sown in a sowing manner, the seeding control mechanism 62 of the seeding regulator 60 is rotated by a predetermined angle with respect to the control main body 61 so that the slit hole 62a is in the tractor traveling direction. The seeds are placed in a straight line, that is, in a shape extending long in the longitudinal direction, so that the seeds are continuously seeded in the longitudinal direction at a predetermined interval with respect to the transverse direction.

In addition, the seedlings are produced on the freshwater surface by the wheel marks of the tractor 10 during the seeding operation. At this time, the mounds of the freshwater surface are evenly spread by the ground puddle 80 extending close to the freshwater surface. will be.

Here, when a rock or other protrusion is formed on the ground during ground leveling operation by the ground leveler 80, the ground pulp plate 81 is pushed upward by the protrusion and then returned to its original state when passing through the protrusion again. In this case, the pus work can be continuously performed.

At this time, since the ground pulp plate 81 pushed upward by the protrusion is elastically supported by the shock absorbing spring 82a, the ground pulp plate 81 is in contact with the ground or the protrusion continuously while being pushed upward. Will be maintained.

And, while the mound is compacted by the ground puddle 81, some of the soil piles that are pushed out and pushed through the incision 81b of the ground puddle plate 81 so as not to accumulate in the pile of dirt. As a result, when the load is not applied to the ground pulp plate 81, pus work is easily performed.

In addition, when not in use, the grounding machine 80 is capable of storing the tractor 10 in a state in which the folded portions 84 of both side ends are reduced in the transverse width, in which case the grounding machine 80 is used. In the case of folding the folding portion 84, the respective latching holes 81a and 84a are aligned on the same line, and then the latching portion 85 is hung to support the folding portion 84 in an unfolded state. When folding the 84, the latch 85 is removed and the folded portion 84 is folded so that the supporting hole 84b is placed on the same line as the through hole 87a of the supporting piece 87. 88 is inserted so that the folded portion 84 is supported in a folded state.

Then, when the rod 24a of the cylinder 24 is extended to rotate the lifting pivot rod 26 backward, the damper (83) pivotally connected to the same rotation shaft 22 is pivoted upward in conjunction with the damper ( It will be able to store by lifting a certain distance from the ground of the ground pulp plate 81, 82).

As described above, the direct wave device using the blowing method of the present invention by using a tractor to automate the seed sowing operation of a large area by the midwife and sowing selection method, so that the seed is scattered and scattered or a certain width while minimizing the damage of the first seed It can be spread evenly at intervals, and also the seeding time is shortened, labor costs are reduced to improve the economy and productivity.
