Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for demulling soil in a mud storage tank, which is used for demulling soil generated from a construction site in a mud storage tank during construction work.

[0002]

2. Description of the Related Art In recent years, a so-called fluidization treatment in which soil such as soil generated at a construction site is fluidized as it is or by adding water thereto, and a solidifying material is added and mixed therewith to be used as a filling material or backfill material. The construction method is in the limelight.

[0003] However, in this method, since the soil such as the soil generated on site contains large lumps and foreign matters, a process of demulling the soil is absolutely necessary. At present, as one of the general methods of demudging, once a soil such as soil generated on site is stored in a mud storage tank, an attachment such as a stirrer or a bucket is attached to a construction machine such as a backhoe, and thereby the mud storage tank is installed. There is a method of demudifying the soil inside.

[0004]

However, in this method, since the operation of the construction machine is performed based on the experience and intuition of the worker, the stirring and demulling device of the attachment comes into contact with the side wall and the bottom of the mud storage tank. Or a collision, damaging the attachment or damaging the storage tank. Therefore, great care is required in operating the machine, which increases the mental burden on the workers.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve these problems. As a mud-removing device, a stirrer or an attachment such as a bucket is attached to a construction machine. It is a device for crushing and demulling soil generated at the site, carried in lumps and the like in the tank, and is a device for crushing soil in a mud storage tank provided with a protective frame so as to surround the crushing device part of the attachment. That is the configuration.

[0006] Further, a protective frame surrounding the mud separator of the attachment is attached to a base shaft of the attachment to form a mud separator for soil in a mud storage tank.

[0007] Further, the protective frame is a device for demulling soil in a mud storage tank having a size that does not make contact with the above-mentioned demulling device.

[0008] The protective frame is a device for demulling soil in a mud storage tank formed of a frame having a void portion in which soil can freely move.

[0009] Since the present invention has the configuration as described above,
When the soil in the mud storage tank is stirred and crushed by the mud crushing device of the attachment of the construction machine, the protective frame provided on the attachment causes the crushing device to directly contact the side wall and bottom of the mud storage tank. Since there is no collision, there is no risk of damaging the attachment or damaging the mud storage tank, so that the mental burden on the worker can be reduced.
Further, since the soil moves through the space portion of the protective frame, a shearing effect on the soil is added, and effective mud crushing can be performed.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an overall schematic view showing one embodiment of the apparatus for demulling soil in a mud storage tank according to the present invention, FIG. 2 is a schematic perspective view of the attachment of the above, FIG. 3 is a schematic front view of the same, and FIG.
FIG. 2 is a schematic side view of the same. 1 to 4, reference numeral 1 denotes a construction machine, 2 denotes a mud separator, which is equipped with an attachment 3 equipped with a stirrer 4, and is protected on a base shaft 3 a of the attachment 3. The frame 5 is attached, but the protective frame 5 is attached so as to surround the stirring unit 4 in a state where the stirring operation of the stirring unit 4 is not hindered. The configuration has a space portion 6 that can be formed.

[0013] The thus constructed mud-removing device 2 is connected to a mud storage tank A.
Normally, it is inserted into the soil or muddy water D accumulated in the inside, and the stirring unit 4 constituting the mud separator of the attachment 3 is rotated, and the attachment 3 is repeatedly moved up and down, back and forth, and left and right while adding water as needed. Perform the demulsification work in the manner described above.

[0012] The stirring section 4 of the attachment 3 during the operation described above.
Is surrounded by the protective frame 5, so that the stirring part 4 of the attachment does not directly touch the side wall B or the bottom plate C of the mud storage tank A. In addition, since the soil moves freely through the space 6 of the protective frame 5, a shearing effect on the soil is added, and efficient mud removal can be performed. After confirming that the soil in the mud storage tank A has been pulverized and fluidized, the pulverization operation is terminated.

In this embodiment, the protection frame 5 is formed in a lattice-like rectangular parallelepiped. However, the present invention is not limited to this. The size and shape of the protection frame 5 and the size and shape of the space 6 are as follows. It goes without saying that various changes can be made without departing from the spirit of the present invention.

[0014] Further, the deflocculating apparatus according to the present invention adds a fluid such as a solidifying material slurry to simultaneously carry out the deflocculation and the production of fluidized soil, or solidifies the sludge by adding the solidifying material to the sludge. It can be widely used for various stirring and mixing methods such as the method of construction.

[0015]

As described above, the present invention is configured as the above-described apparatus for demulling the soil in the mud storage tank. Therefore, the soil in the mud storage tank is stirred and disintegrated by the stirrer of the attachment. When doing
The action of the protective frame provided on the attachment prevents the stirrer from directly contacting or colliding with the side wall or bottom plate of the mud storage tank, thus damaging the stirrer of the attachment or damaging the storage tank. Since there is no risk of damage, the mental burden on the worker can be reduced. Further, since the soil moves through the space of the protective frame, a shearing effect on the soil, such as the impact of the soil on the frame, is added, so that effective mud deflation can be performed.
