, and the pin 34 moves in the direction of arrow D against the spring 35.
direction, and the tip 34a of the pin 34 is pulled out from the positioning hole 31. Next, the small-diameter plow body 1, which has the plow teeth 3 lightly fastened with nuts 4 but does not have the side plates 5 at both ends, is placed on the circular arc portion 16c of the small-diameter plow cylinder main body support 16. The piston rod of the next first hydraulic cylinder device 18 is reduced. Then, the movable support frame 12 is moved in the direction of arrow A, and the tip tapered portion 14a of the movable side fitting body 14
is fitted into one end of the small-diameter plowing trunk body 1, and the small-diameter plowing trunk main body 1 is pushed in the direction of arrow A by the flange 14b, so that the other end of the main body 1 tapers at the tip of the stationary side fitting body 20. It will fit into the portion 25a. As a result, the small-diameter plow body 1 is supported by both fitting bodies 14 and 20 in a state where it is slightly lifted from the circular arc portion 16c. Next, rotate the small-diameter shovel body 1 and
After aligning the through hole 1a with the positioning hole 31, the operation of the air cylinder 37 is stopped. Then, the positioning lock pin 34 is moved in the direction of arrow C by the spring 35, and the tip 34a of the pin 34 is moved.
As shown in FIG. 7, the through hole 1a and the positioning hole 3
Inserted into 1. With this, the small diameter plow body 1
is connected to the fixed side fitting body 20. Next, the fourth hydraulic cylinder device 47 is operated to appropriately raise and lower the elevating body 44 to adjust the height of the insert body 48. Next, operate the second drive motor 76 to move the cart 41 in the direction of arrow B, insert the tip of the inserter 48 into the small diameter plow body 1 through the fixed side fitting body 20, and tighten the nut tightening tool 69. Face Natsu 4 in the back. Next, the rotary actuator 57 is operated to rotate the rotating shaft 54 shown in solid line in FIGS. 5 and 6 by 90 degrees in the direction of arrow H. Then, each sliding plate 62 is slid in the direction of arrow I via each arm 65 and each link 66,
As shown by the imaginary line in FIG. 6, the moving shaft 60 is also moved in the same direction, and the tool 69 is fitted into a predetermined nut 4. The impact during this fitting is absorbed by the spring 73, so that the tool 69 and the nut 4 are not damaged. The next pneumatic motor 74 is activated. Then, the rotating rod 67 is rotated in a predetermined direction, and the tool 69 is also rotated in the same direction via the operating rod 68.
Nut 4 is further tightened. When the nut 4 is sufficiently tightened, the torque limiter stops the operation of the pneumatic motor 74. Next, the rotary actuator 57 is operated to rotate the rotary shaft 54 in the direction of arrow G, move the moving shaft 60 in the direction of arrow I, and move the tool 69 away from the nut 4.
Next, the first drive motor 27 is operated to drive the gear mechanism 2.
8, the fixed side fitting body 20 is rotated by a predetermined angle, and thereby the small diameter plow body 1 is rotated by a predetermined angle in the same direction via the positioning pin 34, and the nut 4 to be tightened next is faced to the tool 69. let At this time, if the tool 69 and its nut 4 are misaligned in the directions of arrows A and B, the second drive motor 76 is operated to move the inserter 48
6 in the direction of arrow A or B as appropriate.
9 should be opposed to the nut 4 to be tightened next. Next, perform the same action as above to remove the tool 69.
Just fit it into the nut 4 and tighten it again. Similarly, each nut 4 may be tightened in turn.

Next, when assembling the large-diameter plow body 2, as in the case described above, the large-diameter plow body 2 is attached to the circular arc portion 17.
c, the piston rod of the second hydraulic cylinder device 19 is reduced and both fitting bodies 15, 21
supports both ends of the large-diameter shovel body 2, and the pin 3
4, the large diameter plow body 1 is fixed to the fixed side fitting body 21.
The piston rod of the third hydraulic cylinder device 45 is reduced to move the slider 42 at the solid line position in FIG.
is slid in the direction of arrow F, so that the insert body 48 faces the large-diameter plow body 2. Next, as in the case described above, the tip of the insert 48 is inserted into the large-diameter plow body 2, and each nut 4 is tightened in turn.

Once the above retightening work is completed, the first

4, 15, 20, 21, pull out the tip 34a of the lock pin 34 from the holes 1a, 31, and remove the plow body bodies 1, 2 on the respective arcuate portions 16c, 17c.

As described above, according to the plow barrel body positioning and connection device in the plow barrel assembly apparatus of the present invention, the positioning lock pin can be inserted into the positioning hole of one of the fitting bodies through the through hole of the plow barrel body. The positioning of the two fittings and the connection to one fitting body rotated by the drive device can be performed at the same time, and such work does not require much effort or time, and the structure is simple and compact. Furthermore, a dog for extracting the tip of the pin from the through hole and the positioning hole is configured to allow the pin to rotate together with one of the fitting bodies when the dog is not engaged with the engaging portion of the pin. Because of this, the dock does not interfere with the rotation of the body.
