Incidentally, in the water absorption mechanism of the tire roller R shown in FIG. 1, the hose H with the strainer S is connected to the first three-way switching valve V1 as shown in the piping diagram of FIG.
From there, it is connected to a water absorption pump P by a hose h1. A hose h2 is connected from the water suction pump P to the second three-way switching valve V2, a hose h3 is connected from the second three-way switching valve V2 to the water tank T, and a hose h4 is also connected to the water spray nozzle N. . The first three-way switching valve V1 is also connected to the water tank T by a hose h5.

Therefore, the water is absorbed by the hose H and is supplied to the water tank T through the first three-way switching valve V1 → hose h1 → water absorption pump P → hose h2 → second three-way switching valve V2 → hose h3. Further, according to the piping diagram, it is also possible to use the water absorption pump as a watering pump, and in that case, from the water tank T to the hose h5 → the first three-way switching valve V1 → the hose h1 → the water absorption pump P → the hose h2 → the second. 2 Three-way switching valve V2 → Water is sprayed from the water spray nozzle N through the hose h4.

The water suction pump P is driven by a hydraulic motor M, which is rotated by hydraulic oil pumped from the hydraulic pump OP, and the hydraulic pump OP is driven by an engine E.

Returning to FIG. 1, an openable / closable lid C is attached to the space for storing the hose. Then, on the side of the hose storage inside the space, the operation panel 1
Is equipped with various switches for water absorption operation and water level indicator lamp 2. In addition,
Although not shown, the above-mentioned various switches and the water level indicator lamp are exactly the same in the driver's seat, so that the operator can perform the water absorption operation as in the conventional case.

When performing work, the main power switch 8 is first turned on and then turned off after the work is completed, so that an inadvertent malfunction is prevented.

The water absorption operation of the compacting machine constructed as described above will be briefly described.

First, the vehicle is moved near the reservoir. Then, the engine is not stopped but its rotation is set to an idle state, and the three-way switch valve is switched to water absorption by the switch lever.

Next, the worker descends to the ground, opens the lid at the rear of the vehicle, takes out the hose, and soaks the tip of the hose in the water of the reservoir. Then take out the handy type operation panel and turn on the main power switch. Next, the engine output is set to a predetermined value by operating the engine control switch to take out work power. Next, the water absorption pump drive switch is operated to start water absorption. If the water level indicator on the control panel or the water level indicator on the vehicle body confirms full water, operate the water absorption pump drive switch to stop water absorption (or stop automatically). Next, operate the engine control switch to return the engine speed to the idle state. Turn off the main power switch on the control panel, store the hose, and return to the driver's seat.

As described above, the worker needs to go down only once on the ground for the water absorption work.
