As shown in FIG. 1 and FIG. 2, the plate compactor 10 is a compaction plate 11 that is in direct contact with the road surface, and is connected to this compaction plate 11, and is a starter that applies vibration and forward / backward movement force to this compaction plate 11. A body case 12 in which a vibrating body (not shown) and the like are housed, an engine 13 elastically mounted on the body case 12, an operation handle 14, and a direction conversion lever 15 provided on the operation handle 14. And a water sprinkling device 16 for sprinkling water onto the pressure plate 11.

As shown in FIGS. 1 to 5, the sprinkler device 16 includes sprinkler pipes 17 a and 17 b provided at front and rear ends of the pressure plate 11, and a water supply hose connected to the sprinkler pipes 17 a and 17 b. 18a, 18b, a water tank 21 fixed to the upper side of the main body, a water supply hose 18c connected to the water tank 21, a water supply hose 18c, and a water supply hose 18a connected to the water spray pipes 17a, 17b. A switching cock 19 provided at a branch position for connecting 18b, a direction changing lever 15 for forward and backward movement of the plate compactor, an interlocking mechanism 22 for connecting the direction changing lever 15 and switching of the water feeding direction of the switching cock 19, and the like. It consists of A water supply stop lever 20 is provided at an intermediate position of the water supply hose 18c connected to the water tank 21.

The interlocking mechanism 22 has a connecting rod 23, one end of which is pivotally supported by the lever 19 b of the switching cock 19, and an intervening piece 24 is rotatably attached to the other end of the connecting rod 23. The tip of the piece 24 is bent into an L-shape, and a pin 26 is pivotally supported between the brackets 25 and 25 which are erected on both sides of the end, and the pin 26 is engaged with the forward-reverse direction changing lever 15. It comprises a U-shaped engagement member 27 which is detachably attached.

As shown in FIG. 4, the interposition piece 24 is attached such that its intermediate position can be rotated coaxially with the rotation fulcrum shaft 15 a of the direction changing lever 15 for forward and backward movement.

Therefore, when the U-shaped engaging member 27 is engaged with the forward-reverse direction-changing lever 15, if the direction-changing lever 15 is tilted forward or backward, the linking members are linked together. The rod 23 moves up and down, and the water supply direction of the switching cock 19 can be switched to the front or the rear.

When the U-shaped engaging member 27 engaged with the forward / reverse direction changing lever 15 is rotated from the solid line in FIG. 4 to the position shown by the imaginary line, the engagement between the two is released, The U-shaped engaging member 27 is cut off from the interlocking relationship with the direction changing lever 15 which moves forward and backward.

The lever 19b of the switching cock 19 has already been operated by the interlocking mechanism 22, and water is sent to one sprinkling pipe (front side when the plate compactor is forward) 17a. Therefore, water is uniformly sprayed from the water spray holes 17e of the water spray pipe 17a to the surface of the pressure plate 11 through the water supply hose 18a over the entire width direction.

When switching the traveling direction of the plate compactor 10 from forward to reverse, the direction changing lever 15 is operated as shown from the phantom line in FIG. 1 to the solid line. At this time, since the U-shaped engaging member 27 of the interlocking mechanism 22 is engaged with the direction changing lever 15, the lever 19b of the switching cock 19 is illustrated via the interposition piece 24, the connecting rod 23 and the like. It is operated as shown by the phantom line from the solid line 1 to switch the water supply passage from the water supply hose 18c to the water spray pipe 17b. Therefore, the water sent from the water tank 21 is sprayed to the pressure plate 11 through the water supply hose 18c, the switching cock 19, and the water supply hose 18b through the water spray holes 17e of the water spray pipe 17b.

When the plate compactor 10 is stopped, the engine is turned off, the water supply stop lever 20 of the water sprinkler 16 is closed, and the direction changing lever 15 to the engaging member 27 are shown by phantom lines in FIG. To leave.
