Of course, the detachable structure of the crushing blade 270 may be realized in various ways, and the structure of the crushing blade 270 may also have various shapes to crush the soil mass.

At the rear of the harrow 200, a plurality of baeto blades 340 are installed at a distance from each other on the rear support frame 310 that is installed long in the width direction of the frame 100, and the rear support frame 310 has on both sides. The other side of each of the rear support arms 320 and 330 is fixed.

In addition, one side of the rear support arms 320 and 330 is rotatably fixed to the pin fixing parts 290 and 291 provided in the front support frame 210 of the harrow 200 to rotate in the vertical direction based on the harrow 200 . This becomes possible.

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

On the other hand, the harrow 200 has a structure in which the frame 100 is supported by means of the warp adjustment units 410 and 410', and the height of the harrow 200 is adjusted by the hardness adjustment units 410 and 410' to plow the plow. The hardness of the part 130 may 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 concentricity of the plow unit 130 .

To this end, the harrow 200 is fixed to the frame 100 via the radial adjustment units 410 and 410', and since both sides of the harrow 200 have the same shape, one hardness adjustment unit 410 ) to explain the structure.

A pair of support pieces 411 and 412 are fixed side by side on the frame 100 at a distance from each other, and a plurality of pin holes 413,414 are formed in the support pieces 411 and 412 at the same position. .

These pin holes 413,414 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 axially installed so that one side thereof is rotated in the vertical direction by a shaft portion 415 between the pair of support pieces 411 and 412 .

In addition, fixing pins 416 and 417 are inserted into the pin holes 413,414 to fix the upper and lower rotations of the front support arm 160 , and the two fixing pins 416 and 417 are installed on the upper side of the front support arm 160 . By being inserted into the pin holes 413,414 from the lower 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 serve as stoppers for restricting the rotation of the front support arm 160 .

A plurality of these pin holes 413,414 are formed in the maximum rotational angle range of the front support arm 160, and the lower end of the pin holes 413,414 formed at the uppermost side supports the front when the front support arm 160 is rotated to the upper side. It is the same height as the upper end of the arm 160, and the upper end of the pin holes 413,414 formed at the lowermost side also has the same height as the lower end of the front support arm 160 when the front support arm 160 is rotated to the lower side. should be

In addition, the interval between each pin hole (413,414) has as much as the thickness of the front support arm (160).

The other side of the front support arm 160 is coupled such that the upper side of the front support frame 210 of the harrow 200 is fixed.

Therefore, when the front support arm 160 is fixed by adjusting the inclination angle by the pin holes 413,414 and the fixing pins 416 and 417 as shown in FIG. 4, the front harrow 200 is grounded on the ground (G) and is supported. The lifting degree of the frame 100 is controlled by the grounding force, and eventually, the depth, that is, the hardness of the plow 130 digging into the ground is controlled.

In other words, if you want to make the center of gravity shallow, the angle of inclination of the front support arm 160 is increased so that the harrow 200 pushes and lifts the frame 100, thereby increasing the separation distance between the frame 100 and the ground (G) to increase the distance between the plow part If you want to adjust the hardness of 130 to be shallow, and conversely to make it deep, the angle of the front support arm 160 is smoothed to decrease the distance between the frame 100 and the ground G, so that the plow part 130 is It is adjusted so that it can dig deep into the ground.

As another form of this latitude adjustment unit 410, a pin hole is formed through the front support arm 160, so that one fixing pin is fastened through the pin hole 413,414 and the pin hole formed in the front support arm 160. It may have a structure that restricts the rotation of the front support arm 160 .

In addition, the hardness of the soiling part 300 is adjusted by the compression and extension of the cylinder 170 , and if you do not want to use the soiling part 300 , the soiling part 300 is moved upwards than the harrow 200 . be able to lift

To this end, when the cylinder 170 is extended as shown in FIG. 5 , the rotation rod 180 rotatably supported by the harrow 200 is rotated 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 the downward direction so that the baetonal 340 digs into the ground (G).

It is possible to adjust the center of gravity of the batonal 340 according to the mounting length of the cylinder 170 .

When the soiling part 300 is not used, the soiling part 300 is supported by the rear support arm 320 and rotates upward by the cylinder 170 being compressed, so that the soiling operation is not performed.

On the other hand, if you do not want to use the harrow 200 together with the soiling part 300 or when moving, remove the fixing pins 416 and 417 of the meridian adjustment parts 410 and 410' 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 rear portion of the rotation rod 180 and the cylinder 170 become straight while the rotation rod 180 rotates forward, so that the pulling force is the harrow 200 ) is applied to the harrow 200 is to be lifted to the upper side of the ground.

Then, the cylinder 170 is compressed or extended to adjust the rotation angle of the front support arms 150 and 160 from the meridian adjustment unit 160. When the fixing pins 416 and 417 are removed and then the cylinder 170 is compressed, the rotation As the liver 180 rotates forward, the harrow 200 rotates upward together with the soiling part 300 , and the front support arms 150 and 160 also rotate upward.

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

Conversely, when the cylinder 170 is extended, the front support arms 150 and 160 rotate downward while the rotation rod 180 rotates backward.

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

The plastering part 300 may have a structure 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 further extends and has a structure in which the rear support arms 320 and 330 are axially installed on the extended frame 100 .

In this structure, the harrow 200 is adjusted by the hardness adjustment parts 410 and 410 ′, and the hardness of the soiling part 300 is adjusted by the cylinder 170 and the rotation rod 180 .

As described above, according to the present invention, the plow work, the harrow work, and the soiling operation can be simultaneously performed, and the hardness of the plow unit 130 and the hardness of the soiling unit 300 can be adjusted as well as the harrow or the soiling operation selectively. it can be done

As described above in detail a specific part of the content of the present invention, for those of ordinary skill in the art, it is clear that this specific description is only a preferred embodiment, and the scope of the present invention is not limited thereby. something to do.
