2. Description of the Related Art Clays such as a ground excavator and a ground consolidation device.
An earth auger having a leader at the top of the vehicle boom or an earth auger having no leader is provided by using a hanging fixture (32) shown in FIG. If you put it in a fixed state,
The drive motor and the earth motor provided at the top of the auger
Due to the rotation reaction force of the gar, the suspension fixture (32) provided on the top of the boom is severely damaged, and in order to minimize this damage, a torque arm is provided between the crane body and the leader. Although there is an apparatus having a configuration in which (21) is laid horizontally, damages due to the influence of the rotational reaction force cannot be avoided. In the case of an earth auger having no leader, an auger guide (33) provided at a lower portion of the earth auger and a crane body (16).
Although there is a device having a structure in which a torque arm (21 ') is laid horizontally between them, the rotational reaction force is large in the hanging fixture (32) in which the driving motor is suspended and fixed to the top of the boom. Affected and could not escape its damage. Further, an auger with a leader or an auger without a leader is provided on the top of the boom.
A large work area is required for installation in a state where the equipment is fixed with the hanging fixtures (32), and the large inconvenience of mounting and removing at a factory in a large place is usually required. is there. That is, there was a great inconvenience that the attachment and detachment could not be easily performed at the work site. There is also the disadvantage that a large truck or work vehicle is required to transport the equipment with the earth auger attached to the top of the boom.

[0007]

Since the present invention has the above-described structure, the earth auger device having a leader can be used with a crane vehicle or a separate vehicle in the present invention. The apparatus is transported to the work site, and the hook (3) provided at the end of the boom is hooked (11) as shown in FIGS.
And lift the earth auger device with the wire (4), and fit the mounting shaft (2) laterally provided at the boom tip (1) into the shaft fitting groove (9) (FIG. 2).
The wire (4) shall be tight and not loosened.
If so, the leader (6) is mounted integrally to the boom tip (1). Then an earth auger with a leader
When the drive motor (5) is set at a predetermined position on the ground and the drive motor (5) is turned (arrow 30), the earth auger (7) excavates the ground. ) Rotation reaction force (arrow 3)
1) is required. However, the leader (6) and the boom are integrally connected at the tip, and the boom tip is
Since the strength of (1) is strong, the rotation reaction force (31) of the earth auger (7) and the rotation reaction force (30) required for the reverse rotation of the ground consolidation can be sufficiently obtained at the joint. Can be When the excavation or consolidation work is completed, the wire (4) is extended to release the fitting of the boom tip (1) and the leader (6). When the rotational reaction force due to the fitting of the mounting shaft (2) and the shaft fitting groove (9) is to be further enhanced, or the parts (2) and (9) are to be protected from any twisting due to the rotational reaction force. At times, use a winch (17) to connect the torque arm (12) to the torque arm holder.
Engage with (14) to reinforce the rotational reaction force. Of course, after the work is completed, the torque arm (1) is again operated by operating the winch (17).
2) Release the engagement between the torque arm holder (14) and the torque arm holder (14). An earth auger device without a leader by fixing connection flares (27) and (27) provided with shaft fitting grooves (9 ') on both sides of the drive motor (5'). Similarly, when the connecting frames (27) and (27) are combined with the mounting shaft (2) provided on the top of the boom, a sufficient rotational reaction force can be obtained. The most important object of the present invention is to combine and attach the boom and earth auger device and to release the boom and the auger device with a wire and a hook provided on the boom and a winch (17) provided on the chassis. Easy to do.

According to the present invention, the mounting shaft (2) and the shaft fitting grooves (9) (9 ') make the leader (6).
Alternatively, since the connecting frame (27) is directly mounted on the end portion (1) of the beam having strong strength, the horizontal rotation of the driving motors (5) and (5 ') is achieved. Due to the rotational reaction force caused by the above, not only the beam tip (1) but also the beam tip (1) and the leader (6) or the connection frame (2) are used.
7) is not damaged by the rotational reaction force. If the torque arm (12) or (12 ') is used, this effect becomes greater. Next, the greatest advantage of the present invention is that the use of the wire (4) and the hook (3) provided in this kind of crane (working vehicle) makes it very easy to use the leader (6). Can be quickly attached to and detached from the boom tip (1) at the work site. Conventionally, the leader is fixedly hung to the end of the boom by the hanging fixture (32) at the factory, so it is extremely difficult to attach and detach the leader, especially once it is attached, it is difficult to remove. Although it is always inconvenient to maintain the attached state because of its existence, it is extremely inconvenient for transportation, etc., but the present invention has a big advantage that it can be easily attached and detached with a crane car by using wires and hooks that are always available. It is effective. Therefore, there is a great effect that attachment and detachment can be easily performed even in a narrow place or a work site. When a retractable torque arm can be easily passed over the winch between the upper position of the main boom and the leader by a winch, the reaction force in the horizontal rotation direction of the drive motor is reduced. Since it can also be obtained by the torque arm, it is very effective to avoid damage to the connection between the tip of the boom and the leader.
