The gearing angle θ of 3 is adjustable. The gearing angle θ is usually about 27 degrees.

According to the embodiment configured as described above, the tilling device (8)
When performing plowing work, power is transmitted from the PTO shaft (3) to the input shaft (11) via the transmission gear, and the tillage device (81) is towed by the tractor (13).

Then, Kaku II! Through the J1 machine purchase tm, the tilling section Q3 is rotationally driven in the up-cut direction indicated by the arrow a, and the plow α3 is also rotationally driven in the direction of the arrow opposite to the tilling section aδ.

Accordingly, the tilling part a'ar in the central part of the tilling device (8)
As well as plowing and crushing work as opening work,
Plow discs 11531 on both left and right sides of tilling section QZ
As it rotates, it cuts into the soil, and at the same time, the soil is cut up and guided along the curvature of the inner surface, turning over and returning to the rear and diagonally inward as unrefined soil, which removes straw, weeds, etc. bury them firmly in the soil by inverting the gravel to promote their corrosion.

The remains of the tilling work are shown in Figure 6.
On both the left and right sides of the plowing section Q3 (6υ), the gravel 1I361 cut and raised by the valley discs I31 tic of the left and right plows and turned over becomes one after the other, and the left and right of the left and right gravel. A groove (6η) is left on each outer side corresponding to the passage trace of the outer disk of each plow 0.

By the way, in the above case, the tilling claws 149] are arranged symmetrically around the horizontal center position of the tilling part UVc, and the tilling claws 149 are arranged on each left and right side of the tilling part surface.
]t- Since the left and right sides are directed outward, the tilling claws on the left and right sides of the tilling section surface can be used to blow the tilled soil symmetrically forward and diagonally outward, resulting in a mouth-opening effect due to the tilling section. The soil reversal work using the disc of the plow 0 can be done well, and the plowing surface of the plowing section can be
(6) There is no mounding of gravel soil (661), and the plowing marks in plowing area a are in good condition.

In addition, since the tilling section o'e is rotated in the up-cut direction, even if there is straw etc. on the ground in the field,
When the tilling claws 149) come out of the soil, they collide with straw etc. through the tilled soil lumps and blow away the straw etc. with the tilled soil lumps, so that it is difficult for straw fat to get entangled with the tilling claws.

FIG. 7 shows a second embodiment of the present invention, in which the drive mechanism (
141 is a bevel gear on the tilling shaft side (661), a bevel gear on the Dinuku shaft side (57) having a smaller diameter, and a lower intermediate bevel gear (57) on the tilling shaft side (having a larger diameter than 561 and meshing with the gear from below). 8''4, an upper intermediate bevel gear (83) that has approximately the same diameter as the disk shaft side bevel gear (5'7!) and engages with the gear (57) from above, and an intermediate shaft. Rain intermediate bevel gears ((2) (82) are fixedly installed at the upper and lower ends of (3), and the intermediate shaft (70
) are rotatably supported between the inner case. In addition, the outer cane (73) is inserted into the vertically intermediate part of the inner case g, and rotatably supports the intermediate shaft νυ, and the axis of the intermediate shaft VQ [>ffi is the center of the plow. Zeng is rotatable.

The interlocking groove allows the tilling shaft [4710 rotations to be faster than the rotation of the disc shaft, for example, the rotation speed between the tilling shafts is about 170 to 420 rpm,
Since the rotational speed of the disk shaft is about 11 Orpm, and the tilling section surface and the plow 0 are driven to rotate at suitable rotational speeds, the tilling section qz and the plow U can perform the work well.

In the embodiment, a bevel gear transmission mechanism or the like is used as the interlocking mechanism, but other transmission mechanisms such as a universal joint as shown in FIG. 4 may also be used. Alternatively, the tilling section may be driven to rotate in the down cutting direction.

<Effects of the Invention> As described in detail above, according to the present invention, each Dinuk shaft is moved rearward and diagonally outward from the left and right ends of the tilling shaft through an interlocking mechanism that interlocks the tilling shaft and the Dinuk shaft. Since it extends to the side, the length of the entire tilling device in the front and rear direction can be made shorter than before, and therefore, the weight balance between the tractor and the tilling device can be made good, and the tilling device can perform the tilling work well. The drive mechanism for the tilling section and the plow can also be simplified. In addition, since the drive mechanism is a mechanism that drives the JILF tiller part and the plow in full rotation from the lateral center of the tiller part, the drive mechanism can be constructed easily, and it is possible to reduce the number of plows. Even in the case where the gearing angle can be adjusted, the structure of the drive device 1'i does not become complicated, and the gearing angle can be easily adjusted. Further, the tilling section M of the present invention can be easily configured using a normal center drive rotary tiller. For example, when the tiller shaft of the center drive rotary tiller is rotationally driven in the down-cut direction. By directly connecting the disc shaft of the plow to the tilling shaft via a universal joint, the tilling shaft and the Dinuk shaft can be interlocked and connected.

The present invention has the advantages of each of the above songs, and is a real advantage.
