The filter 2 is to filter the field extraction soil, as shown in Fig. 1 to 2, a plurality of filters (22a, 22b) are installed in the case 21 in the upper and lower two stages or two or more stages. The filters 22a and 22b vibrate through the field collecting soil and filter out bulky ones such as impurities and aggregates.

As described above, the vibration means for vibrating the filters 22a and 22b may be made in various forms. As an example, the motor M1 and the cam C1 may be used as shown in the drawing. That is, when the motor M1 drives and the cam C1 rotates, the cam C1 rotates and vibrates the filters 22a and 22b closely attached to the upper portion thereof. One end of the filter 22a and 22b is a fixed end fixedly vibrated by a hinge axis, and the bottom of the free end is vibrated by the cam C1 which rotates in close contact with the cam C1. Therefore, when impurities or aggregates are filtered out in the filters 22a and 22b, the filter 22 is rotated around the hinge axis to remove the filtered impurities and aggregates.

It is preferable that the filter 2 has a larger mesh than the upper filter 22a provided at the upper side than the lower filter 22b provided at the lower side. As such, when the mesh of the upper filter 22a becomes large, impurities or aggregates larger than the lower filter 22b are filtered out of the upper filter 22a, thereby preventing the upper filter 22a from clogging.

The storage tank (3) is to store the field harvested soil passing through the filter (22a, 22b) of the filter (2), the inlet 31 is formed at the top and the outlet (23) of the filter (2) Correspondingly located and the outlet 32 is preferably formed at the bottom of the bottom surface. The outlet 32 of the storage tank 3 is connected to the honey tank 4 and the supply pipe (F) to supply the stored on-site collection soil to the honey tank (4).

The capacity of the storage tank 3 is preferably input to the controller (CT). In this case, when the storage tank 3 is filled with the on-site collection soil, the controller (CT) recognizes the amount thereof and supplies the dry soil or coal ash to the honey tank 4 to adjust the water content of the on-site collection soil which will be described later. The supply of soil or coal ash can be easily determined.

The honey tank 4 is connected to the storage tank 3 by the supply pipe (F), and is supplied by the pump P of the field extraction soil filtered from the storage tank (3). The honey tank 4 is rotatably installed inside the stirring blade 41 so as to stir and mix the supplied on-the-spot soil and dry soil or coal ash added to adjust the water content of the on-site soil. The stirring blade 41 is fixed to the shaft 42, the plurality of which is rotatably fixed up and down. In addition, each of the shafts 42 is connected to the motor M2 and the power transmission means 43 is rotated when the motor M2 is driven forward and backward to rotate the stirring blade 41. The stirring blade 41 is fixed in a zigzag manner as shown in the figure to increase the exchange efficiency.

Here, the dry soil and coal ash added to adjust the water content may be used separately or may be used together.

The first density meter (D1) is installed on the supply pipe (F) path between the storage tank (3) and the honey tank (4) to measure the density of the field harvesting soil supplied to the honey tank (4), the measurement The data is sent to the controller CT. In this way, when the first density meter D1 sends the measured data to the controller CT, the controller CT checks the water content of the soil-collected soil by the density, and when the water content ratio is higher than the water content preset in the microcomputer, the honey tank (4). ) And dry soil or coal ash are added to set the water content ratio.

At this time, the amount of dry soil or coal ash is determined according to the measured water content error and the amount of on-site mining soil, the amount of on-site mining soil may be determined according to the capacity of the storage tank (3) as described above. In other words, since the capacity of the storage tank 3 is input in advance to the controller CT, when the storage tank 3 is supplied to the honey tank 4 while the storage tank 3 is fully charged, the amount of the storage soil 3 is automatically used. Is determined.

Another method of measuring the amount of on-site mining soil is to directly measure the on-site mining soil supplied to the honey tank 4 through the supply pipe (F) to determine the diameter of the inner diameter of the supply pipe (F) and the flow rate of the on-site mining soil supplied. By multiplying, it is possible to simply calculate the amount of on-site mining soil supplied to the honey tank (4). To this end, a flow rate meter (not shown) is installed in the supply pipe (F).

The water content control tank (5) is to supply the dry soil or coal ash to the honey tank (4) to adjust the water content of the on-site mining soil, an additive, that is, dry soil or coal ash is stored therein. Therefore, the water content adjustment tank 5 is opened and closed the automatic valve in accordance with the command of the controller (CT) is supplied / blocked to the drying tank or coal ash to the honey tank (4).

A plurality of stirring tanks 6 are connected in parallel to the honey tank 4 and the supply pipe (F), the primary slurry and solidified storage tank (HT) supplied from the honey tank (4) by the pump (P). ) And the cement and water supplied separately from the water tank (WT) to form a secondary slurry by stirring each other.

The stirring tank 6 is provided with a rotatable stirring blade 61 therein so as to stir the secondary slurry. The stirring blade 61 is fixed to a shaft 62 in which a plurality of rotor blades are rotatably fixed up and down like the honey tank 4, and each of the shafts 62 is provided by a motor M3 and a power transmission means 63. Connected. When the motor M3 is driven forward and backward, the stirring blade 61 rotates to stir the secondary slurry.

Each stirring tank 6 configured as described above is arranged in parallel to the honey tank 4, but the drawings of the present invention show that two are installed. Each of the agitator tanks 6 drives two at the same time to make secondary slurries. Since the secondary slurries are alternately sequentially supplied to the storage tank 7, the mixed soil can be continuously manufactured, and thus the mixed discussion Productivity can be increased. As such, the stirring vessel 6 is arranged in parallel, which is one of the features of the present invention, which is not known in the conventional mixed soil manufacturing apparatus.

In addition, the driving of each stirring vessel 6 is to increase the driving time if the target density of the mixed soil to be produced by the controller (CT) is high to perform the mixing of the secondary slurry for a long time, if the target density is low to shorten the driving time Mixing can be shortened.

The second density meter (D2) is installed on the supply pipe (F) path connecting between the honey tank 4 and each stirring tank (6) to measure the density of the primary slurry supplied to each stirring tank (6) The measurement is then sent to the controller (CT). When the second density meter D2 sends the measured data to the controller CT, the controller CT calculates the amount of the supplied primary slurry and the density of the primary slurry measured by the second density meter D2. Analyzing to control the supply of the cement and water preset in accordance with the measured amount and density of the primary slurry to the stirring tank (6).

Here, since the amount of the primary slurry is the sum of the amount of on-site mining soil and dry soil or coal ash supplied to the honey tank (4), it can be easily confirmed because it is calculated by the controller (CT).

The solidification storage tank (HT) is connected to each of the stirring tank (6) by a pipe, and stores a solidifying agent such as cement supplied to the stirring tank (6), by the command of the controller (CT) of the automatic valve The cement is supplied to the stirring vessel 6 by the opening and closing operation.

The storage tank (7) is connected to each stirring tank 6 and the supply pipe (F) in parallel, the stirring blades 71 rotatably installed inside the secondary slurry sequentially supplied from each stirring tank (6) By stirring. The stirring blades 71 are fixed to a shaft 72 in which a plurality of them are rotatably fixed up and down like the honey tank 4 and the stirring tank 6, and the respective shafts 72 are driven by the motor M4. It is connected to the transmission means (73). When the motor M4 is driven forward and backward, the stirring blade 71 rotates to stir the secondary slurry.

An upper part of the reservoir 7 is formed with an inlet through which secondary slurries supplied from each stirring tank 6 connected in parallel are formed, and the inlet is further provided with a vibrable filter 74. The quantity of the filter 74 corresponds to the supply pipe F connected in parallel, so as to vibrate the filter 74 while the cam rotates with the rotation of the motor in the same manner as the filters 22a and 22b of the filter 2. Configured.

The reason why the vibrating filter 74 is installed at the inlet of the reservoir 7 is to filter out the lump when the secondary slurry made in the stirring vessel 6 is supplied in a lump form without being released. If the filter 74 is not installed, the slurry in the form of agglomerate may be blocked when the slurry is pumped to the factory, and even if the filter 74 is supplied, the quality of the product may be reduced.

The presser (8) is installed on the supply pipe (F) path piped from the reservoir (7) to the city factory, and pressurizes the secondary slurry stored in the reservoir (7) to the city factory. Although the pressure pump is a well-known technique, a detailed description thereof will be omitted.
