A presser plate is attached to the outer surface of the first rotation converter, and a support plate is attached to the side of the work machine to the outer surface of the second rotation converter via a mounting rod. The support plate is screwed and fixed via mounting bolts to two mounting bosses, upper and lower, which protrude at symmetrical positions on the circumferential line centering on the input shaft on the outer surface of the input shaft. A bolt insertion hole for screwing into the mounting boss located above the second rotation conversion part is formed approximately halfway, and a hole is formed at the lower edge around the bolt insertion hole for screwing into the lower mounting boss. It is characterized by having a curved horizontally elongated hole, and a vertically elongated hole formed in the upper edge thereof to be screwed and fixed to the working machine via a connecting bolt.

The support plate 8 has a substantially isosceles triangular shape when viewed from the front, and the second rotating exchange portion is disposed approximately midway on the vertical center line thereof.
Input shaft 2 viewed from the upper side of the outer surface of C ₂ , that is, from the side.
A bolt insertion hole 8a for screwing the mounting bolt 6 is provided in the screw hole 3a of the mounting boss 3 located on the upper side, and a bolt insertion hole 8a for screwing the mounting bolt 6 is provided on the lower edge of the mounting boss 3 located on the lower side of the input shaft 2.
In order to screw the mounting bolt 6 into the screw hole 3a, a horizontally elongated hole 8b is formed in a curved shape with the bolt insertion hole 8a as the center, and the upper end edge is provided with a mounting rod 7 for connecting to the plowing leveling machine B. A vertically elongated hole 8c is formed in each case to be screwed and fixed with a bolt 9 (FIG. 5).

The support plate 8 has the bolt insertion hole 8a and the horizontally long hole 8b connected to the mounting boss ₃ of the second rotation converter C2.
3 through the screw holes 3a, 3a, and connect the connecting bolt through the mounting rod 7 between the mounting piece B', which is provided in the vertically elongated hole 8c on the upper edge of the plowing leveling machine B. 9, and the second rotation conversion part
Attach and fix C ₂ to the plow leveling machine B.

Thus, the power transmission device C transfers its first rotation converting portion _C1 to the tiller main body A by means of the holding plate 5, and transfers its second rotation converting portion _C2 to the tiller body A by means of the support plate 8.
It is attached to and fixed to.

Next, the power transmission device C using the support plate 8 and the presser plate 5
Explain how to install.

First, the holding plate 5, which is to be attached to the tiller main body A, is screwed and fixed to the attachment bosses 3, 3 on the outer surface of the first rotation conversion part _C1 with the mounting bolts 6, and the second rotation conversion part C1 is screwed and fixed. Mounting boss 3 on the outside surface of C ₂ ,
3, a support plate 8 is temporarily screwed and fixed with a mounting bolt 6. Then, a connecting bolt 9 is inserted into the vertically elongated hole 8c of the support plate 8, and is temporarily screwed and fixed to the plowing leveling machine B via the mounting rod 7. That is,
The second rotation converter C ₂ is temporarily attached to the puddling leveler B, and the holding plate 5 is screwed and fixed to the tiller main body A via the mounting rod 4, and the first rotation converter C ₁ is removed from the tiller. Attach and fix to machine body A.

Then, the mounting bolts 6 are screwed into the second rotation converter C ₂ and the plowing leveling machine B in a temporarily fixed state, respectively.
By completely tightening the connecting bolts 9, the installation and fixation of the power transmission device C is completed.

Therefore, the installation angle of the power transmission C is as shown in Fig. 3A,
As shown in FIG. 2, the second rotation converter C ₂
Even if the position of the mounting boss 3 on the outer surface of the mounting boss 3 is displaced, the support plate 8 moves around the bolt insertion hole 8a in accordance with the displacement, and the connecting bolt inserted through the vertically long hole 8c and the horizontally long hole 8b on the upper and lower edges. 9 and the mounting bolt 6 is absorbed (adjusted) by the vertically elongated hole 8c and the horizontally elongated hole 8b (double-dot chain lines in Fig. 3).

As mentioned above, the present invention is designed to attach the second rotation converting part of the power transmission machine to the working machine (plowing leveler) at an approximately midway point on the vertical center line of the support plate for attaching and fixing the second rotation converting part to the working machine (passing leveler). The lower edge has a bolt insertion hole that screws into the mounting boss located on the lower side, the lower edge has a curved horizontal hole that is opened around the bolt insertion hole that screws into the lower mounting boss, and the upper edge has a curved horizontal hole that is opened around the bolt insertion hole that screws into the lower mounting boss. It has a vertical hole that is screwed and fixed to the work equipment via a connecting bolt.
Even if the installation angle of the power transmission device that connects the output shaft of the tiller and the input shaft of the work equipment differs depending on the model and manufacturer, the installation angle (tilt angle)
It is possible to absorb (adjust) positional deviations due to differences in the position of the power transmitter, which is convenient because the power transmission can be immediately mounted and fixed at any mounting angle.
