A watering mechanism B is mounted on the rear part of the body frame 9, a wire drum 13 for winding the alignment device C and the wire 1 on the front part, and a power transmission part on the center part. It is covered with a cover 10b.
[0008]
The water sprinkling mechanism B has a base tube 4 erected at the center of the rear, projects a connecting tube 2 from the bottom of the base tube 4 to the rear, and connects a water supply hose 3. The other end of the hose 3 is connected to a pump. The pressure water can be supplied.

The wheel 16 is rotated, the coaxial wire drum 13 is rotated, the wire 1 is wound up, and the unmanned water truck A moves forward.
Note that a one-way clutch is provided on the rotating shaft portion of the transmission shaft 11 so that the unmanned water truck A does not move backward even if the pivotal support tube 4b rotates in the reverse direction.
[0011]
Next, the configuration of the alignment apparatus of the present invention will be described with reference to FIGS.
The alignment device C has a portal-type support frame 20 erected on the front portion of the wire drum 13 of the body frame 9, and a support shaft 21 is pivotally supported at the center of the horizontal portion 20 a of the support frame 20. An alignment plate 22 is pivotally supported as a rotating member, and is arranged so as to be positioned in the support frame 20. The alignment plate 22 is formed in a disk, and a large number of locking holes 22a, 22a,... Are opened at regular intervals along the outer periphery (at an equal pitch). A wire guide 23 is suspended. The wire guide 23 is configured in a ring shape, and a shaft portion 23a at the upper end thereof is pivotally supported by the alignment plate 22 so that the wire 1 is passed through the lower ring.

[0012]
Then, a support shaft 25 is horizontally provided on the vertical portion 20b of the support frame 20 and protrudes rearward. A midway portion of the rotation arm 26 is pivotally supported on the protruded support shaft 25 as a driven rotating body. A pivot pipe 27 is fixed to the moving arm 26 so as to be rotatable on the support shaft 25, and a torsion spring 29 is externally fitted to the pivot pipe 27, and both ends thereof are connected to the pivot arm 26. The pivot arm 26 is hooked on the support frame 20 and urged to rotate counterclockwise as viewed from the rear.
Further, a base portion of the locking arm 31 is pivotally supported at the upper end of the rotating arm 26, and a claw portion 31a is formed at the tip of the locking arm 31, and the claw portion 31a protrudes downward to project the alignment plate. 22 is inserted into the locking hole 22a. A spring 32 is interposed between the locking arm 31 and the rotating arm 26, and the claw portion 31a of the locking arm 31 is biased in the direction of insertion into the locking hole 22a.
On the other hand, a roller 33 is pivotally supported at the lower end of the rotating arm 26, and the roller 33 is biased by the torsion spring 29 so as to abut on the side surface side of the wire drum 13. A protrusion 13a is provided on the side surface of the wire drum 13 with which the roller 33 abuts, so that the roller 33 gets over while abutting by rotation during winding of the wire.
[0013]
A bracket 34 is fixed to the front of the horizontal portion 20a of the support frame 20 so that the left and right positions can be adjusted. A stop arm 35 is pivotally supported by the bracket 34, and a claw portion 35a is provided at the tip of the stop arm 35. The claw portion 35 a can be inserted into the locking hole 22 a of the alignment plate 22.
However, as shown in FIG. 3, the claw portions 31 a and 35 a have an inclined portion that is permissible with respect to the rotation direction of the alignment plate 22 and is configured to block in the reverse rotation direction.
[0014]
With this configuration, when the pivot tube 4b is rotated by the discharge from the nozzles 24a and 24a, the wire drum 13 is rotated through the power transmission unit, and the roller 33 rides on the protrusion 13a, the rotating arm 26 rotates to the right (in rear view) and the locking arm 31 also moves to the right, and the claw portion 31a once gets over the alignment plate 22 and enters the adjacent locking hole 22a. At this time, the alignment plate 22 tries to rotate left (reverse), but the rotation is blocked by the claw portion 35a of the restraining arm 35.
When the wire drum 13 is further rotated and the roller 33 passes through the protrusion 13a, the rotating arm 26 is rotated counterclockwise (rear view) by the urging force of the spring 29, and the locking arm 31 is also moved leftward. At this time, the claw portion 31a is rotated by one pitch of the locking hole 22a so as to draw the alignment plate 22 while remaining in the locking hole 22a. At this time, the claw portion 35a of the restraining arm 35 gets over the slope in the escape direction and enters the adjacent locking hole 22a.
However, if the direction of inclination of the claw portions 31a and 35a in the escape direction is reversed, the alignment plate 22 can be rotated in the reverse direction, and is rotated when the roller 33 rides on the protrusion 13a.
[0015]
Thus, when the wire drum 13 rotates once, the alignment plate 22 is rotated by one pitch of the locking holes 22a, and the wire guide 23 is rotated in the same manner (at this time, the wire guide 23 passes through the wire 1 so that it faces the front). When the wire is continuously wound up, the wire guide 23 reciprocates left and right when viewed from the front, and the wire 1 is guided by the wire guide 23 and the wire drum 13. It will be wound up in line.
[0016]
As another arrangement of the aligning device, as shown in FIG. 5, a traverse shaft 40 and a guide shaft 41 as rotating members are horizontally mounted on support frames 20 ′ and 20 ′ erected on the body frame 9, and the traverse A wire guide 42 is fitted to the shaft 40 and the guide shaft 41, and the wire guide 42 is moved in the axial direction along the groove on the traverse shaft 40, and is slidable on the guide shaft 41 in the tangential direction. The wire guide 42 is inserted into the wire guide 42 so as to be reciprocated by the rotation of the traverse shaft 40.
A star-shaped (or sprocket-shaped) driven rotating body 43 is fixed on one side of the traverse shaft 40, and protrusions 43 a, 43 a... Protruding from the driven rotating body 43 protrude from the side surface of the wire drum 13. It arrange | positions so that contact | abutting to the provided protrusion (pin) 13a '. Therefore, when the wire drum 13 is rotated by the operation of the watering mechanism B, the driven rotating body 43 is rotated by one pitch for each rotation of the wire drum 13, and the wire guide 42 is moved in the lateral direction. When continuously rotated, the wire guide 42 reciprocates on the traverse shaft 40 to align and wind the wire 1.
