に2本を一組として固定してある。 In order to stir and mix the soil strengthening agent more efficiently, there is also a device that has a basic structure similar to an agricultural rotary tiller (unspecified literature). FIG. 6 shows an example of such a rotary ground improvement device. This device has a drive mechanism 42 consisting of hydraulic motors 40, 40 and chain transmission mechanisms 41, 41 on the left and right sides of a main body with a gate-shaped cross section, and a drive shaft 43 between the lower ends of the left and right chain transmission mechanisms 41, 41. A large number of crushing claws 44 are attached to this shaft 43. 45 is a cover that prevents the scattering of earth and sand, and 46 is a backhoe arm.

In the rotary ground improvement device that stirs the soil while rotating the crushing claws 44 as described above,
The entire device tends to lift off the ground due to the reaction force generated when the soil crushing claws 44 sink into the ground.
Therefore, the entire device does not penetrate into the soil at the initial stage, and the penetration angle tends to become small. If the entry angle is small, the work locus must be largely overlapped in the front and back, resulting in a decrease in processing efficiency.

The ground improvement device is used, for example, as shown in FIG. 3, by using a backhoe 1 as a driving main machine and attaching it to the tip of its arm 22. As the arm 22 descends,
First, the pilot claw 32 is driven into the soil, and then the soil crushing claw 5 is driven into the ground. At this time, a driving reaction force acts on the rotary body 3, but the pilot claws 32 already in the soil capture the mud,
Since the attitude of the rotary body 3 is maintained against the reaction force, the rotary body 3 sinks smoothly into the soil at a large penetration angle without causing initial uplift.

According to the soil improvement device 2 of the present invention as described above, the rotary main body 3 can be driven into the soil at a large penetration angle, so the amount of overlap of the work trajectories of the soil improvement device 2 can be made as small as possible. Efficiency of ground treatment work can be improved. Furthermore, the lifting of the rotary body 3 due to the driving reaction force of the crushing claws 5 is suppressed by the vanes 30 and the pilot claws 32, thereby eliminating variations in the depth of the crushed soil and making the finished improved ground uniform. This makes it possible to improve the quality of the treated road surface and eliminate partial road surface depressions in roadbeds, parking lots, etc.

By attaching the device 2 to the arm 22 of the backhoe 1 and operating the boom 25 and arm 22, it is used in a state where it is pulled toward the backhoe 1 side. A hydraulic motor 11 that drives the pawl shaft 7 is driven by pressurized oil supplied from the backhoe 1.
The direction of rotation is switched by a switching device of the control valve.

ができる。 The initial position in which the boom 25 and arm 22 are extended and the rotary body 3 is sunk into the ground is shown on the right side of FIG. In this state, the soil crushing claws 5 are not in contact with the ground, and only the pilot claws 32 are stuck into the soil. By pushing down the arm 2 while swinging the rotary body 3 clockwise with the bucket cylinder 24, the crushing claws 5 are gradually sunk into the ground. At this time, the driving reaction force of the crushing claws 5 acts to lift the rotary body 3, but the pilot claws 32, which are already in the soil, catch the mud and lift the rotary body 3 against the reaction force. To prevent floating, the rotary body 3 is connected to the bucket cylinder 24 and the arm 2.
It penetrates into the soil at a large penetration angle along the trajectory specified in 2. Therefore, the amount of overlap between the trajectory of entry into the soil at this time and the trajectory of the previous work can be reduced, and the efficiency of the ground treatment work can be improved.

る。 As shown on the left side of Fig. 4, even when the rotary main body 3 sinks to a predetermined depth of crushed soil, a reaction force in the uplift direction acts, causing the ground condition to change suddenly and hardness and density to increase. In such cases,
A large force in the lifting direction acts on the rotary body 3. However, when the rotary main body 3 is sunk to a predetermined depth, the blades 30 are in a nearly horizontal position, and although there is not as much resistance when moving forward and backward, there is a large resistance when moving up and down. It is in a state of generating force. Therefore, even if a reaction force in the lifting direction as described above acts, the resistance force of the vanes 30 prevents the rotary main body 3 from lifting up, and the depth of crushed soil can be prevented from becoming shallow. As a result, although the device 2 of the present invention continuously repeats crushing in a pendulum motion, it is possible to eliminate variations in the depth of crushed soil and achieve homogeneous ground improvement. The pilot pawl 32 and the sand guide plate 35 also assist the wing plate 30 to generate a resistance force in the opposite direction to the uplift force.

For example, the wing plate 30 may be formed into a U-shaped frame, and the rising frames at both ends of the wing plate 30 may be formed into a U-shaped frame shape. The parts may be fixed to the opposite walls of the side frames 8, 8. In this case, the lower ends of the side frames 8, 8 can be aligned with the lower end position of the chain case 15, thereby making it possible to reduce the weight. In addition, the attachment posture of the wing plate 30 to the side frames 8, 8 can be changed,
It may be possible to adjust the depth of crushed soil.
翼板30を長手方向中央部が前方に突出する犂
形状にして、翼板30の地面へのくい込み動作を
よりスムーズなものとすることもできる。 The vane plate 30 may be shaped like a plow whose longitudinal center portion protrudes forward, so that the blade plate 30 can be driven into the ground more smoothly.
ドライブ機構4は第6図のようにロータリ本体
3の両側に設けてもよく、ロータリ本体3の中央
一個所に設けてもよい。 The drive mechanism 4 may be provided on both sides of the rotary body 3 as shown in FIG. 6, or may be provided at one location in the center of the rotary body 3.
攪拌子6は、爪ブラケツト17に対して、必ず
しも傾斜させる必要はなく、例えば爪ブラケツト
17の突出方向と直交する状態で多層状に配設し
てもよく、要は土砂の混合・攪拌を行えるもので
あれば、棒状体にするなどその構造は限定しな
い。 The stirring bars 6 do not necessarily have to be inclined with respect to the claw brackets 17, and may be arranged in multiple layers, for example, perpendicular to the protruding direction of the claw brackets 17, in short, they can mix and stir the earth and sand. The structure is not limited, as long as it is a rod-shaped object.
