The vibrating screen base 30 is supported by the plurality of elastic members 33 to vibrate the excavation bucket 10 for the backhoe. That is, the vibrating screen base 10 vibrates by connecting the outer frame 31 of the vibrating screen base 30 and both side plates 12 of the backhoe excavating bucket 10 by the elastic member 33.

Soil mass screening and soil purification method according to this embodiment

As shown in (a) of FIG. 15, the backhoe is a state in which the earth and sand excavation and vibration screening apparatus according to the first embodiment described above is removed from the vibrating sieve screen 50 from the vibrating screen base 30. (1) mounting;

As shown in FIG. 15 (b), the first step of digging the contaminated soil (S) by the backhoe excavation bucket (10);

As shown in (c) of FIG. 15, the priming excavated contaminated soil (S) is pumped into the backhoe excavation bucket (10);

As shown in (d) of Figure 15, the first step of sorting the contaminated soil (S) carried by the backhoe excavating bucket 10 by the vibration screen base (30);

Attaching the vibrating sieve (50) to the vibrating screen base (30) as shown in FIG. 15 (e);

As shown in FIG. 15 (f), the final soil excavation by the backhoe excavation bucket 10 in the state in which the vibrating sieve screen 50 is attached;

As shown in Figure 15 (g), the step of pumping the final excavated contaminated soil (S) to the backhoe excavation bucket (10);

As shown in FIG. 15 (h), the final step of sorting the contaminated soil (S) raised by the vibrating sieve screen 50 attached to the vibrating screen base 30;

In the above-described backhoe 1 mounting step, the backhoe 1 is mounted on the tip of the arm 3 of the backhoe 1 using the backhoe mounting portion 17 provided on the top plate 11 of the backhoe excavation bucket 10 (FIG. 15). (A)).

In the initial drilling step, the soil soil (S) is excavated using the backhoe excavation bucket 10 as in the excavation operation of the bucket of the normal backhoe (see Fig. 15 (b)).

In the step of spreading the primitive excavated contaminated soil (S), the soil contaminated soil (S) by refracting the boom (2) and the arm (3) of the backhoe excavation bucket (10) The backhoe to be buried in the excavating bucket 10 (see Fig. 15 (c)).

In the step of first screening the contaminated soil (S) spread in the backhoe excavation bucket 10, the backhoe excavation bucket (10) by the refractive action of the boom (2) and the arm (3) of the backhoe (1) The soil soil (S) spread in the backhoe excavation bucket (10) by lifting the) to be sorted by the particle diameter through the mesh of the vibration screen base 30 (see Fig. 15 (d)).

At this time, by vibrating the vibrating screen base 30 by the vibrating means 60, the first selection of the contaminated soil (S) is made more smoothly.

That is, when the rotational force of the rotational power source (not shown) is transmitted to the driving rotational element 64a through the reduction gear 65, the rotational force of the driving rotational element 64a is transmitted through the transmission element 64c to the driven rotational element 64b. ), The cam shaft 61a fixed to the driven rotary element 64b rotates, the vibration generating cam 62 fixed to the camshaft 61 rotates, and the vibration screen base The vibrating screen base 30 vibrates while the upper end portion of the 30 comes in contact with the vibration generating cam 62.

In addition, the rotational force of the camshaft 61a is transmitted through the interlocking rotation element 64d fixed to the other end of the camshaft 61a and the transmission element 64f and the interlocking rotation element 64e fixed to the other end of the camshaft 61b. The camshaft 61b is transmitted to the camshaft 61b so as to rotate in conjunction with the camshaft 61a, and the vibration generating cam 62b fixed to the camshaft 61a rotates.

As such, when the vibrating screen base 30 vibrates, the contaminated soil lumps are broken and the contaminated soil, which is buried on the surface of the bulk material such as stone or waste concrete, is dropped off, and the selection proceeds.

In this case, when the cam follower 63 is rotatably installed in the vibrating screen base 30, the vibrating cam 62 does not directly contact the vibrating screen base 30, and the vibrating screen base ( Since the cam follower 63 rotatably supported by 30 is brought into contact with the vibration generating cam 62, the vibration generating operation by the vibration generating cam 62 is smoothly performed.

Contaminated soil (S) in the process of going through the first excavation step and the first screening step as described above will have an effect equivalent to inverting the contaminated soil in the conventional contaminated soil tillage technology.

In addition, after the initial excavation step and the initial screening step for the contaminated soil (S), the moisture and oil in the contaminated soil (S) will evaporate a considerable amount to eliminate the contaminated soil lumps, The soil contaminated on the surface will be eliminated.

In the step of attaching the vibrating sieve screen 50 to the vibrating screen base 30, the vibrating sieve screen 50 is attached to the vibrating screen base 30 by binding with a wire or using a bolt and a nut. (See FIG. 15E).

In the final excavation step, in the state in which the vibrating sieve screen 50 is attached to the vibrating screen base 30, excavated contaminated soil S selected by the backhoe excavating bucket 10 (FIG. 15). (F)).

In the step of spreading the final excavated contaminated soil, the first selected contaminated soil (S) by refraction operation of the boom 2 and the arm (3) of the backhoe excavation bucket 10 is The backhoe to be buried in the excavating bucket 10 (see Fig. 15 (g)).

In the final step of sorting the contaminated soil (S) spread in the backhoe excavation bucket (10), the backhoe excavation bucket (10) by the refractive action of the boom (2) and the arm (3) of the backhoe (1) By raising the) so that the contaminated soil (S) spread in the backhoe excavation bucket 10 is selected by the particle diameter through the mesh of the vibrating sieve (50) (see Fig. 15 (h)).

In the final screening step, the vibration screen 60 generates vibration in the vibration screen base 30, and the vibration generated in the vibration screen base 30 is transmitted to the vibration screening network 50, so that the final screening process is performed. It will work smoothly.

Since the process of generating vibration by the vibration means 60 is as described above, a detailed description thereof will be omitted.

The final excavation step and the final screening step described above may be completed once, or may be repeatedly performed two or more times depending on the site situation such as pollution degree of the contaminated soil.

Even in the final excavation step and the final screening step described above, the conventional soil contaminated soil tillage technology has an effect equivalent to inverting the contaminated soil.

As described above, in the soil mass screening and soil purification method according to the present invention, the vibration screening net 50 is attached after the initial drilling step and the initial screening step in the state in which only the vibration screen base 30 is attached. The reason for performing the final excavation step and the final screening step sequentially in the state is as follows.

In the early stages of cultivating contaminated soils, contaminated soils are wetted by moisture and oil, and in this state, the aggregated contaminated soil masses are mixed in a large amount, and contaminated soils are buried on the surface of the bulk material such as stones or waste concrete. When the bar is present in a coarse state, the vibrating sieve screen 50 is immediately attached in this state and undergoes the final excavation step and the final screening step. The vibrating sieve screen 50 is formed by the soil contaminated by moisture and oil. This is because the network is blocked and selection is not made smoothly.

In addition, in the final screening step, the bulk material having a particle size larger than the minimum screening particle size does not pass through the mesh of the vibrating sieve network 50, and the bulk material having a particle size smaller than the minimum screening particle size is the vibration screening net ( It should be mixed in the soil cultivated through the network of 50). In the early stages of tillage of the contaminated soil, the contaminated soil is wetted by moisture and oil, and the bulk material to be screened is contaminated with the contaminated soil on its surface. This is because the bulk material smaller than the particle size of the minimum screening object to pass through the mesh of the vibrating sieve screen 50 does not pass through the mesh of the vibrating sieve screen 50 because it exists in a larger state.
