The more the adjustment hole 522 fixed with the fixing hole of the support bar 530 is the adjustment hole 522 closer to the coupling bar 521, the more the guide blade 510 rotates upward, and accordingly, the guide blade 510 ) Can increase the opening angle. On the other hand, as the adjustment hole 522 fixed with the fixing hole of the support bar 530 is the adjustment hole 522 far from the coupling bar 521, the guide blade 510 is slightly rotated upward, and accordingly, the guide blade The opening angle by 510 can be reduced.

When the opening angle of the guide wing 510 increases, the soil sprayed upwards among the soil sprayed from the top part 300 may be discharged to the outside, so that the scattering distance increases and thus it can be sprayed away. On the other hand, when the opening angle of the guide wing 510 decreases, the soil sprayed to the upper side of the soil sprayed from the top part 300 fits the guide wing 510 so that the scattering distance becomes shorter and can be sprayed closer to the covering device. have.

In summary, when the cover device coupled to the agricultural manager moves while operating, the soil S of the cultivated land is pumped upward by the excavation unit 200. Accordingly, where the excavation part 200 passes, a furrow F may be formed.

The soiling part 300 discharges and sprinkles the soil S raised by the excavation part 200 to both sides. And as the first wing 330 and the second wing 340 of the soiling portion 300 rotate in the opposite direction, some of the soil S1 of the soil S spread by the excavation portion 200 is the first It is sprayed to one side of the excavation device by the wings 330 and stacked to form a ridge (R). In addition, the other part of the soil S2 among the soil S raised by the excavation part 200 may be sprayed and stacked on the opposite side of the excavation apparatus by the second wing 340 to form a ridge R. . In this way, the furrow (F) and the furrow (R) can be formed at the same time.

At this time, the scattering distance of the soil S1 and S2 to be sprayed may be adjusted by adjusting the first and second control units 400 and 500. That is, by lowering the height of the fence 410 of the first adjustment unit 400 or by reducing the opening angle of the guide blade 510, the scattering distance of the soil to be scattered (S1, S2) can be shortened, and this Through this, the ridge can be formed relatively close to the covering device. Alternatively, by increasing the height of the fence 410 of the first adjustment unit 400, or by increasing the opening angle of the guide blade 510, the scattering distance of the sown soil (S1, S2) can be increased, and this Through this, the ridge can be formed relatively far from the covering device.
