Next, the use of the fumarole type soil improvement machine of this embodiment will be explained together with the operation of the above-mentioned outer pipe pulling machine @b.

First, as shown in FIG. 1, with the main body A held at the stop position llS close to the upper limit, the frame B is tilted to ground the wheels 41, and the handle portion 30a of the handle stand 30 is Push the fumarole-type soil conditioner to the location where the fumarole will be applied. Here, the grounding frame 37 is grounded and the frame body B is made to stand upright on the soil. In this state, the upper guide roller 313 is supported by the weight receiving part 335a of the weight receiving tool 335 provided in the fall prevention mechanism 33 (see FIG. 18), and the lower end of the nozzle 13 of the outer pipe 12 is connected to the ground frame 37.
The main body is located above the road from the lower end and is held by the frame B so that it does not fall.

Further, the belt 35 is spirally wound around the take-up pulley 24, and the clutch 21 is held in a clutch disengaged state in which the clutch pawls 242 and 251 are disengaged.

In this state, the fall prevention lever 332 is
When the support of the guide roller 313 by the weight receiving part 335a of the weight receiving tool 335 is released, the main body A slightly lowers with respect to the frame due to its own weight, and the lower end of the nozzle 13 is installed. At the same time, 1 of the main body A is attached to the outer pipe 12.
! Due to the action of the solder, the receiving body 12a provided at the upper end of the outer pipe 12 for sliding movement with the inner vibe 8 comes into contact with the cam 21a, and the total weight of the outer vibe 12 is transferred to the main body via the cam 21a. It is attacked by the receiver 12a. At the same time, because the old cam a is eccentric, the receiving body 12a is struck by the pressing force due to the rotation of the cam 21a. At this time, since the entire weight of the main body A acts on the receiving body 12a via the cam 21a as described above, the striking action by the cam 21a is performed under the load of the entire weight of the main body A, and this striking action causes As the main body A descends, the outer vibe 12 is efficiently driven into the soil.

Note that during this driving, since the clutch 27 is in the disconnected state, the driving force is not transmitted from the intermediate shaft 15 to the take-up pulley 24, and the belt 35 is transferred from the take-up pulley 24 to the take-up pulley 24.
is being unrolled with almost no resistance, while the main body A is moving towards the frame B
It goes down against.

As described above, after the outer vibe 12 is driven to the required depth to reach the lowering limit of the main body A, the pedal 711 is pressed to open the kneading valve 7 and the high pressure air in the air tank 5 is pumped into the tip of the outer vibe 12. The blowhole 1 of the nozzle 13 is set in
Spray into the soil from 3a.

Since the operating rod 712 rotates together with the rotation of the pedal shaft 706 due to the pressure of the pedal 111, the operating rod 11
2, the closing arm 272 is pushed, the cylinder shaft 215 rotates, the shifter 277 rotates, the clutch 25 moves toward the take-up pulley 24 against the spring 26, and the clutch pawl 251
and 242 are engaged. Therefore, the driving force of the engine 1 is transferred to the intermediate shaft 15. Reducer 22. Output shaft 23° clutch 25
The belt 35 is wound around the take-up pulley 24, and the main body A begins to rise relative to the frame B via the take-up pulley 24. As the main body A rises, the receiver 12a is attached to the buffer 1 by the protector 9a of the stroke cylinder 9.
Outer vibe 1 supported through 0 and driven into the soil
2 is pulled out. At this time, the main body A is the guide roller 313
is guided by the strut 29, the posture during stirring is controlled, and the outer vibrator 12 is pulled out vertically. Furthermore, as the belt 35 is wound around the take-up pulley 24, the diameter becomes larger, so the main body A is slow at the beginning of its rise, and gradually rises faster as it goes up a, making it impossible to raise it in a short time. In addition, since the lifting speed at the initial stage of pulling out, which requires the greatest force to pull out the outer vibrator 12, is slow, there is less burden on the engine 1 and the drive power transmission system. and,
When the outer vibe 12 is pulled out from the soil, the main body A rises above the stop position llS, and the upper guide roller 3
13 retracts the weight receiving part 335a of the weight receiving shell 335 from below against the spring 336 and reaches above it. Note that the pressure on the pedal 111 should be released in a timely manner, and the operation valve 1 should be released in a timely manner.
to chime in.

When the main body A rises as far as it can go, the collision between the abutment body 36 and the cutoff arm 274 causes the clutch 25 to be moved in the direction away from the take-up pulley 24 via the shifter 277, and the clutch pawls 251 and 242 are moved. disengage and disengage the clutch. As a result, the take-up pulley 24
The driving force is no longer transmitted from the engine 1, and the lifting operation is stopped. In this state, the main body A tries to fall due to gravity, but the weight receiving part 335a of the weight receiving tool 335 hits again with the restoring force of the spring 336, and prevents the main body A from falling. It is held at the stop position S. Therefore, by folding down the frame B and using the wheels 41, the blower type soil improvement machine was installed.
Remove from the area where fumarole is present in the soil.

As explained above, the fumarole-type soil improvement machine of the present invention uses the full weight of the main body as well as the rotation of the cam that utilizes the power of the engine to drive the outer vibrator into the soil, making this work easier. It can be easily and automatically done in a short time with little effort, and by raising the main body relative to the frame using a drive source such as an engine installed in the main body, it is possible to pull out the 7 Utavipes that have been driven into the soil. (Since it is possible to
This work can be done easily with little effort, and since the rising speed of the main body is slow at the beginning of the rise (but becomes faster as it rises), there is no need to overload the engine or drive power transmission system. The effect is that 7 pipes can be pulled out in a short time.
