BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raw material feeder for a fluidized soil, which supplies a mixed soil of soil and solidified material, water, and the like, which are raw materials for the fluidized soil, used for filling and filling of voids, to a mixing kneading apparatus.

A fluidization treatment method has been proposed in which soil, solidified material, water and the like are mixed and stirred to form a fluidized soil, and the filling and voids are filled using the fluidized soil.

This fluidization treatment method has the advantage that it is possible to effectively use construction residues such as excavated soil, to reduce the labor required for filling work, and to fill in a narrow space.

The above-mentioned fluidized soil is a fluidized plant having a honey plant which mixes excavated soil with water to form a modified soil, and a mixed dough plant which mixes the adjusted soil, water and cement to form a fluidized soil. It is manufactured in a processing plant.

In addition, the above-mentioned fluidized soil is manufactured by mixing the excavated soil into a mixing kneader (drum or paddle type) of a mixer car with a bucket type dropper, and then mixing and kneading the cement and water.

Since the above-mentioned fluidization plant requires a lot of equipment and cannot be moved, it is very difficult to convey the fluidization soil when the working environment is far away.

In the case of using the above-mentioned mixer car, it is inexpensive and excellent in maneuverability, and conveyance of a fluidized soil is easy.

However, when the excavated soil is put into the mixing kneader of the mixer car, the viscous soil becomes agglomerates and is likely to be clogged at the inlet of the mixing kneader. When rotating the mixing kneading device of the mixer car, it does not loosen and remains lump, and the mixing property is bad, and in particular, clay soil takes time because it is difficult to loosen.

In addition, since soil is put into the bucket of the hydraulic excavator and the amount of soil is managed by how many times the bucket is put into the bucket, the deviation is large and difficult to manage.

An object of the present invention is to provide a raw material feeder for a fluidized soil treated to solve the above problems.

When signals of the mixed soil conveyance device switch 60-1 and the mixer switch 60-2 are input to the controller 52, the controller 52 controls the motor 56 and the mixer 3 of the mixed soil conveyance device 10. ), The motor 61 of the small cutter 15 and the motor 62 of the impact hammer 16 are driven. After that, when a signal is input from the raw material soil conveyance apparatus 60-3, the motor 50 and the motor 63 of the discharging motor 21 are driven.

When the detection signal of the above-mentioned raw soil sensor 7a is input to the controller 52, the controller 52 drives the motor 53 to rotate the fixed-quantity supply mechanism 23, and supplies solidified material onto the raw soil. do. The solidified material can also be supplied directly to the mixer 3.

After that, when the first predetermined time elapses (mixed soil is discharged), the motor 31 is driven to discharge water.

During the above operation, the controller 52 controls the rotation speed of the motor 53 based on the raw material soil supply amount, the solid material supply amount, and the mixing ratio thereof to control the rotation speed of the fixed-quantity supply mechanism 23.

For this reason, let it be the value which set the mixing ratio of a raw material soil and a solidified material.

In addition, the controller 52 stops motors other than the motor 31 when the detected mixed soil conveyance amount is set, and stops the motor 31 when the water supply amount is supplied at a ratio set.

For this reason, it can supply to the mixing dough apparatus 41 of the mixer car 40 by the total supply amount which set the mixed soil, water, and solidified material.

The recording device 64 is connected to the controller 52.

This recording device 64 is equipped with an API monitor 65, a printer 66, and a DC-DC converter 67, and after operating the raw material soil conveyance device switch 60-3 mentioned above, each supply amount is set amount. When each motor stops, the raw material soil supply amount, the solidified fire supply amount, and the water supply amount are displayed on the AIP monitor 65 together with the year, month, and time, and printed out.

Next, a second embodiment of each supply amount control will be described.

The total raw soil amount required by each setting means, the total solid amount required, and the total amount of water required are input to the controller 52.

The start switch 60 is operated to input a start signal to the controller 52.

The controller 52 drives each motor, and stops the motor 50 and stops the raw material soil conveyance apparatus 7 when the detected raw material soil supply amount sets the total raw material soil amount.

When the detected amount of solidified fire supply is the total amount of solidified fire, the motor 53 is stopped to stop the fixed-quantity supply mechanism 23.

When the detected amount of water supply reaches the set amount of water, the motor 30 is stopped to stop the liquid pump 30.

After that, when the predetermined time elapses, the remaining motor is stopped.

It is not necessary to provide a means for detecting the amount of raw soil conveyed.

The up and down swing of the mixed soil conveying apparatus 10 may be made free.
