That is, the protrusion 321 is pressed against the farmland floor by a load of the roller portion 320 to form a ditch, and the slope 322 is formed so that the ditch is formed in a V shape such that the seed is located in the center of the ditch , And the blade 323 can easily pass through the gravel buried in agricultural land.

The driven shaft 330 may include a first tooth 331 fastened and fixed to the opposite side where the gear is provided.

The first tooth 331 may be provided to engage with the second tooth 612 provided in the seed supply part 600 to provide rotational power to the second tooth 612. That is, when the tractor 1 is moved, the roller 320 rotates to rotate the drive shaft 310. When the drive shaft 310 rotates, the driven shaft 330 rotates and simultaneously rotates the first tooth 331 At this time, the second tooth 612 engaged with the first tooth 331 is rotated.

The soil compaction unit 400 may be formed of a drum type roller and is rotatably coupled to the other side of the body 200 opposite to the kneader 300 and may be provided to support the surface of the seeded farmland . That is, after the ditch is formed by the dougher 300, the dough is discharged from the seed supply part 600 to the ditch, and the dirt compaction part 400 is covered with the dirt, Let the seed press the ground where it is received.

The replicator 500 may be fixedly coupled between the kneader 300 and the soil compaction unit 400 and may be installed to collect the soil that has been digested by the kneader 300 and to flow into the trench. That is, due to the ditch formed by the kneader 300, soil is accumulated on both sides of the ditch. At this time, the accumulated dirt is introduced into the ditch again by the combiner 500. The replicator 500 may include a support 510, a fixed frame 520, and a cover plate 530.

In addition, the support table 510 is fixed to the pipe pipe 233 by using a bolt provided outside the pipe pipe 233 in a state of being inserted into the pipe pipe 233. That is, after the supporter 510 is moved upward or downward so that the surge plate 530 can touch the surface of the farmland, the supporter 510 is fastened to the pipe 233 by fastening the bolts provided outside the pipe 233, .

The fixed frame 520 may be fixed to the lower portion of the support 510 by welding or the like, and the earthenware refuse 521 may be formed on one side adjacent to the knocker 300.

The earthenware refuse 521 may be provided in proximity to the blade 323 provided in the kneader 300 and may be provided to remove foreign substances or mud etc. adhered to the blade 323.

In addition, the end of the clogged refuse 521 facing the blade 323 may be formed in a round shape. In other words. The lower frame 220 may be rotated with respect to the center axis of the drive shaft 310 when the surface of the blade 323 is in an uneven farming state. At this time, in the state where the end of the clogged refuse 521 is close to the blade 323, Direction.

The cover plate 530 is coupled to a shaft provided on the fixed frame 520 so as to be rotatable within a fixed range on the fixed frame 520 on the opposite side of the clog rejection 521, May be provided to cover the trench.

The bucket plate 530 may also include a torsion spring 531 that restricts upward rotation about an axis and a stopper 532 that limits rotation to the bottom.

One end of the torsion spring 531 is fixed to the fixed frame 520 while the other end of the torsion spring 531 is fixed to the ground plate 530 and the ground plate 530 is fixed to the fixed frame 520 in the downward direction To be rotated.

For example, when the soil cover plate 530 is pressed by the torsion spring 531 to a ground surface, the soil accumulated on both sides of the trough can be easily introduced into the trench.

The stopper 532 may be provided under the fixed frame 520 and may be provided to support the bucket plate 530 rotated downward by the torsion spring 531.

For example, when moving to an ordinary road other than a farmland, the cover plate 530 may come in close contact with the ground surface of the general road and be broken by friction. To prevent breakage of the cover plate 530, It is possible to restrict the plate 530 from rotating in the downward direction.

The seed supplying part 600 is fixed to the support frame 230 and accommodates various kinds of seeds and the like so that the seeds can be automatically discharged by the movement of the tractor 1. [ The seed supply part 600 may include a body 610, a fixing pin 620, and a fixing protrusion 630.

The body 610 may be formed in a hopper shape to accommodate various seeds and the like.

In addition, the body 610 may include a shaft-coupled rotating body 611 at an inner lower end thereof, and a second tooth 612 disposed at an outer side of the rotating body 611 and coupled to the shaft.

The rotating body 611 is formed in a cylindrical shape, and is formed with grooves spaced apart from each other by a predetermined distance in the circumferential direction, and can be rotated by the second teeth 612. That is, when the seed held in the body 610 is accommodated in the groove formed in the rotating body 611 and the second tooth 612 is rotated, the rotating body 611 is rotated with respect to the center of the shaft, Is discharged to the outside. In this way, the seeds are automatically discharged in the longitudinal direction of the trench at a predetermined interval.

The second tooth 612 is engaged with the first tooth 331 and receives the rotational power transmitted from the first tooth 331 to rotate the shaft inserted into the rotating body 611 and rotate by the second tooth 612 The rotating shaft 611 can be rotated again.

The fixing pin 620 is inserted into the lower part of the body 610 through which the seed is discharged and is inserted into the insertion groove 231 formed in the support frame 230 so that the body 610 is detached upward . That is, both ends of the fixing pin 620 are inserted into the insertion groove 231 formed in the shape of a long hole so as to be slanted downward at a predetermined angle while sliding.

The fixing protrusions 630 are formed on the opposite side of the body 610 in which the fixing pins 620 are inserted, and insertion holes 631 penetrating through the fixing protrusions 630 may be formed on both sides. That is, the seed supply unit 600 may be provided to easily and conveniently detach the support frame 230.

For example, after the fixing pin 620 is inserted into the insertion groove 231 while the fixing pin 620 is inserted into the body 610, the fixing protrusion 630 is inserted into the fixing portion 232a The bent portion 232b is inserted into the insertion hole 631 by elasticity.

When the fixing pin 620 and the fixing protrusion 630 provided on the body 610 are used as described above, there is an advantage that the seed supplying part 600 can be easily and conveniently attached to and detached from the support frame 230.
