There is.

This type of illumination device has disk rotors extending in the left-right direction that are configured symmetrically with a central transmission part as a boundary, and the left and right disk rotors are moved back and forth in a horizontal plane with respect to the traveling direction. It has a shaft-supported structure that allows gearing angle adjustment, and the left and right disc rotors are forcibly rotated by power transmission from the PTO shaft via the universal joint. By arranging the disks with their curved concave surfaces facing inward or outward, the soil can be shaped into high ridges.
It is reversed to the II collapse form and Ura 11 is raised.

(Technical Problem of the Present Invention) By the way, in the LLT rotor device as described above, in order to change and adjust the gearing angle of the left and right disc rotors, the rotor frame is pivotally supported on the main frame, and the intersection angle between the main frame and the rotor frame is adjusted. However, it is not possible to select the Guyang angle steplessly, and it is necessary to know the angle accurately, but I rely on intuition to know the Guyang angle. That is the reality.

(Objective of the present invention) The present invention solves the problem of selecting the Guyang angle, which previously relied on the intuition of the operator.
In addition, the selection of the plowing width is determined by the movement of a sliding body that is movably attached to the main frame, and the movement is converted into a gearing angle and further into a plowing width (the purpose is to be able to display it). That is.

(Technical Means of the Present Invention) For this purpose, the present invention provides a structure in which a rotor frame is pivotally supported relative to the 1-frame so as to be rotatable in a horizontal plane, and is slidably attached to the main frame. A certain sliding body and the rotor frame are linked and connected so that the linear movement of the sliding body is converted into the rotational movement of the rotor frame, and the amount of movement of the sliding body is adjusted by 7 angles and 11 widths. The present invention is characterized in that it is configured so that at least one of them can be displayed.

, one end 35a of the interlocking rod 35 is shown, and the other end 351) of the interlocking rod 35 is supported so as to be slidable back and forth at the rear of the main frame 1.
Pivotally connected to the rest body. The sliding body 4 includes a hydraulic cylinder 5 that accommodates a piston rod 51 whose base end is pivotally connected to the horizontal bar 14 between the right vertical bars 11 and 12 of the main frame 1.
The base ends of the slide body 4 are connected to each other so that the slide body 4 slides along the vertical beams 11, 12 of the main frame 10 after m by the expansion and contraction operation of the hydraulic cylinder 5 which is the drive source of the slide body 4,
A hydraulic regulator 6 that operates this hydraulic cylinder 5 is installed in a blind space formed below the transmission box 2 between the left and right vertical bars 11 and 12 of the main frame 1, and is connected to a belt from the input shaft 21 of the transmission box 2. It is designed to be driven via a transmission system 24.

By moving this sliding body 4 along the length direction of the main frame 1, the attitude of the rotor frame 33, that is, the disk 3
2 is changed, and the sliding body 4
The vertical bar 11 of the main frame 1 has a scale 41 as a gearing angle display mechanism so that the gearing angle can be displayed at the position of the gearing angle. The old width is 12 ().

The transmission box 2 has output shafts (not shown) that protrude in the left-right direction, and a power transmission shaft 26 connected to each output shaft via a conniversal joint 25 extends sideways along the rotor fly 1133. The other end of the rotor frame 33 is connected to a side transmission system in a transmission case 36 formed on the outer ring side of the rotor frame 33 via a universal joint. The rotational power is transmitted to the rotor shaft 31 of No. 3. The power transmission shaft 26 has a structure in which the shaft portion is extendable and retractable, and the disc rotor 3 is adapted to the working speed of the tractor (rotation speed of the disc). On the other hand, Kosoku Maro (about 3.
It is designed to rotate at a speed of 5 times or more.

Regarding the left and right rotor frames 33, a support arm 37 is protruded forward LJ from each rotor frame so as to be able to swing left and right about a vertical pin 38. At the front end, a column 71 with a stabilizing shaft 1 supported at its lower end is mounted so that it can be adjusted up and down (M), and by adjusting the stabilizing shaft 1 (F) down, the depth of cultivation by the disc rotor 3 can be regulated. That's how it is. Therefore, each of the stabilizing shafts 7 supports the stabilizing shaft 7 so that it always rotates around an axis perpendicular to the traveling direction without being affected by the gearing angle adjustment of the left and right nine disc rotors 3.3. The support arms 37 are connected to the vertical bars 11 of the main frame 1 via parallel links 39 arranged parallel to the respective rotor frames 33.
．． To 12! ! l! has been done.

A central tillage processing mechanism 8 is provided at the front of the inner end sides of the left and right disc rotors 3.3 configured as described above. This central tillage processing mechanism 8 pivots a pair of left and right disks 81.81 in a V-shape plane so that their curved concave surfaces face outward and their circumferential front portions approach each other in the direction of travel. Therefore, especially in the present invention, the base end portion of the support arm 83 that cantilever supports each support shaft 82 of the pair of disks 81 is connected to the main frame 1 via the vertical bin 84.
The left and right discs 81 and 81 are pivotally supported at the lower front end of the disc so as to be able to swing left and right, and the left and right discs 81 and 81 are pivotally supported so that they can approach or move away from each other using the vertical bin 84 as a fulcrum. The support arm 83 of the supporting arm 83 elastically moves both disks 81.81 in the direction of mutually opening (41a) by means of an elastic body 85. The rear end is fixed to the main frame I side, and the front end is a free end and comes into contact with the inner surface of the support arm 83. The spring force of this elastic body 85 at least The pair of left and right disks 81.81 are set to have an opening force necessary to form an opening interval of -L equal to or larger than the shaft diameter of the drive shaft 22 between the two discs. Reference numeral 86 is a stopper for regulating the opening interval, and in addition, the left and right disc rotors 3.
A chisel 87 is attached between 3 and has the function of crushing any remaining amount after the center 411 processing + the 11 processing by the horizontal 8.

With this configuration, when the tractor 8 is moved forward to perform plowing work at 1tτ, the power transmitted via the tractor's PTO shaft 23 or 61ni liveshaft 22 causes the left and right disc wheels 3, 3 of the tractor to move forward. The soil is rotated at a higher speed than the working speed (disc rotation speed), and the disks 32 of the rotatably driven computers 3, 3 turn the soil inwardly, plowing it up, and creating a high ridge shape (kamabot shape). ), these left and right disc rotors 3,
Reversal by 3, prior to plowing, central 11 fields]! 1!
A pair of left and right disks 81.81 that make up the mechanism 8 cut into the uncultivated land in front of the middle part of both disks 3, 3, and divide the soil in the center to the left and right by the rotation of the disks 81.81. Plow.

At this time, the left and right pair of disks si and ai receive inward lateral pressure from each other due to the backward resistance caused by the forward movement, so both disks 81 and 81 are moved by their respective elastic bodies 8.

The subsequent left and right disks 1]-ta 3,
Soil inversion and plowing according to step 3 will be performed accurately.

In addition, when lifting the tiller 11Fj in one direction when going around the ridge, the central tiller 4M is raised by raising the tiller.
8 is not pulled up to the ground, the tillage resistance (,1
Since it is resolved, both disks 81.81 are bullet 41
Due to the spring force of the body 85, a gap larger than the axial diameter of the drive shaft 22 is formed between both disks 81°8117il, and due to the formation of this gap, the center II ki
N place 1! I! The river disk 81.81 is arranged so that the drive shaft 22 passes through the gap without interfering with the drive shaft 22 arranged in longitudinal direction 1) on its 1 side, and the 4Il device is lifted high above the ground. I can do it.

In particular, the key 11i of the Guyang angle of each disk 32,
By supplying pressure oil to the oil cylinder 5, the expansion and contraction of A can be achieved.As a result, when the sliding body 4 moves along the main frame 1, its linear motion is transmitted to the rotor frame via the interlocking rod 35. 33 is rotated around the sub-v1 pin 38 which is a pivot point. The operator reads the position of the sliding body 4 at this point using the scale 41 serving as the Guyang angle display mechanism, and
