A connection portion 350 is provided at the central portion of the rear support frame 310 so that the rear portion of the rotation shaft 180 is rotatably installed by a pin 182.

On the other hand, the harrow 200 has a structure in which the frame 100 is supported by the optical center adjustment units 410 and 410 ′, and the height of the harrow 200 is adjusted by the optical center adjustment unit 410 and 410 ′. The depth of the unit 130 can be adjusted.

That is, by adjusting the height of the harrow 200, the height of the front of the frame 100 is adjusted to adjust the depth of the plow part 130.

To this end, the harrow 200 is fixed to the frame 100 via the optical center adjustment units 410 and 410 ′. Since both sides of the optical center adjustment units 410 and 410 ′ have the same shape, one optical center adjustment unit 410 Explain the structure around ).

In the optical center adjustment part 410, a pair of support pieces 411 and 412 are fixed at intervals from each other on the frame 100, and a plurality of pin holes 413 and 414 are formed at the same position in the support pieces 411 and 412. .

These pin holes 413 and 414 are formed in the vertical direction, and are preferably formed to follow the rotation path of the front support arm 160.

The front support arm 160 is installed so that one side of the front support arm 160 rotates in the vertical direction by a shaft 415 between the pair of support pieces 411 and 412.

In addition, the fixing pins 416 and 417 are inserted into the pin holes 413 and 414 to fix the rotation of the front support arm 160 in the upper and lower directions, and two fixing pins 416 and 417 are placed on the upper side of the front support arm 160. By being inserted into the pin holes 413 and 414 respectively from the and lower sides, the front support arm 160 is caught by the fixing pins 416 and 417 and is fixed so as not to rotate.

That is, the fixing pins 416 and 417 function as a stopper for restricting the rotation of the front support arm 160.

A plurality of these pin holes (413,414) are formed in the range of the maximum rotation angle of the front support arm (160), and the lower portion of the pin holes (413,414) formed on the uppermost side is forward support when the front support arm (160) is rotated upwardly It is the same height as the upper part of the arm 160, and the upper part of the pinholes 413 and 414 formed at the lowermost side is also the same height as the lower part of the front support arm 160 when the front support arm 160 rotates to the lower side. Should be.

In addition, the interval between the pin holes 413 and 414 is as much as the thickness of the front support arm 160.

The upper side of the front support frame 210 of the harrow 200 is coupled to the other side of the front support arm 160 so as to be fixed.

Therefore, when the front support arm 160 is fixed by adjusting the inclination angle by the pin holes 413 and 414 and the fixing pins 416 and 417 as in FIG. 4, the front harrow 200 is grounded to the ground G to hold it. The degree of lifting of the frame 100 is adjusted by the grounding force, and as a result, the depth at which the plow unit 130 digs into the ground, that is, the center of gravity is adjusted.

That is, if you want to make the center of gravity shallow, the inclination angle of the front support arm 160 is increased and the harrow 200 pushes and lifts the frame 100 to increase the separation distance between the frame 100 and the ground (G). If you want to adjust the center of gravity of (130) to be shallow and, on the contrary, to deepen the center of gravity, by making the angle of the front support arm (160) smooth, the distance between the frame 100 and the ground (G) is reduced, so that the plow part 130 is It is adjusted so that it can dig deeper into the ground.

As another form of such an optical center adjustment part 410, a pin hole is formed through the front support arm 160 so that one fixing pin penetrates through the pin holes 413 and 414 and the pin hole formed in the front support arm 160 and is fastened. It may have a structure that restricts the rotation of the front support arm 160.

In addition, when the cylinder 170 is compressed and elongated, the center of gravity of the embedding part 300 is adjusted, and in the case of not using the embedding part 300, the embedding part 300 is moved above the harrow 200. You will be able to lift it.

To this end, when the cylinder 170 is elongated as shown in FIG. 5, the rotating shaft 180 rotatably supported by the harrow 200 rotates backward, and accordingly, the front support frame 210 of the harrow 200 ), the rear support arm 320, which is rotatably fixed to the bottom, rotates in a downward direction, so that the top blade 340 penetrates the ground (G).

According to the mounting length of the cylinder 170, it is possible to adjust the depth of the top blade 340.

When the top part 300 is not used, the cylinder 170 is compressed, so that the top part 300 is supported by the rear support arm 320 and rotates upward, so that the top part does not work.

On the other hand, when it is desired not to use the harrow 200 together with the top plate 300 or when moving, the fixing pins 416 and 417 of the optical center adjustment unit 410 and 410 ′ are removed to release the restraint state of the front support arms 150 and 160 When the cylinder 170 is further compressed by making it rotatable, the rotation rod 180 rotates forward and the rear portion of the rotation rod 180 and the cylinder 170 become straight, so that the pulling force becomes the harrow 200 ) Is applied to the harrow 200 is lifted to the upper side of the ground.

In addition, the cylinder 170 is compressed or elongated to adjust the rotation angle of the front support arms 150 and 160 from the radial center adjustment unit 160. When the fixing pins 416 and 417 are removed and the cylinder 170 is compressed, the rotation As the liver 180 rotates forward, the harrow 200 rotates upward together with the top part 300 so that the front support arms 150 and 160 also rotate upward.

When the fixing pins 416 and 417 are inserted back into the pin holes 313 and 314 while the front support arms 150 and 160 are rotated, rotation of the front support arms 150 and 160 at that position is restricted.

On the contrary, when the cylinder 170 is elongated, the front support arms 150 and 160 rotate downward while the rotation shaft 180 rotates backward.

Therefore, by adjusting the height at which the harrow 200 contacts the ground by the rotation of the front support arms 150, 160, the depth of the plow part 130 is adjusted, and the rotation angle of the front support arms 150, 160 is adjusted to the cylinder ( 170) can be easily adjusted.

The top part 300 may have a structure that is directly connected to the frame 100 rather than the front support frame 210 of the harrow 200, and in this case, the frame 100 is moved to the upper side of the harrow 200. It is further extended, and has a structure in which the rear support arms 320 and 330 are built in the extended frame 100.

In this structure, the core of the harrow 200 is adjusted by the center of gravity control units 410 and 410 ′, and the core of the top part 300 is controlled by the cylinder 170 and the rotational space 180.

As described above, the present invention can simultaneously perform plowing, harrowing, and soiling, and also able to adjust the core of the plowing unit 130 and the core of the soiling unit 300, as well as selectively selecting the harrow or soiling operation. It can be done.
