DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant for producing improved soil from excavated soil and recycling it as backfill material in order to reuse a large amount of excavated soil generated in public works.

[0002]

2. Description of the Related Art Conventionally, a large amount of excavated soil generated in public works is deposited in a stock yard, regenerated in a large plant installed on the ground, and reprocessed into improved soil such as backfill material. .

[0003] Therefore, it is difficult to provide a large plant for obtaining the above-mentioned improved soil in a place where the stock yard is dispersed in many places and a relatively small amount of excavated soil is deposited. However, there is a problem that it is difficult to use for small-scale construction such as burying in a buried groove of a wiring duct or the like.

[0004]

DISCLOSURE OF THE INVENTION The present invention provides a method for reclaiming a relatively small amount of backfill material required for plumbing work on roads or the like from small excavated soil in a small-scale stock yard, and for a small-scale stock yard. The purpose of the present invention is to obtain an excavated soil recycling processing plant that can move according to the conditions.

[0005]

In order to achieve the above object, the present invention provides a main conveyor in the front-rear direction on a carrier such as a truck, and one end of the main conveyor faces an upper part of a mixer provided on the carrier. A roll screen is arranged above the other end of the main conveyor, a lime powder feeder is arranged in the middle upper part, and a mixture conveyor is provided on a lower bed of the mixer, and the mixture screen and the screen are sieved. The excavated soil recycling treatment plant mixture conveyor, which is configured so that the unloading conveyor can be removably mounted on the loading bed, is capable of rotating forward and backward, and the mixture screen and the unsifting conveyor under the screen are placed on the right or left side of the loading platform. The excavated soil recycling plant according to the first aspect of the present invention, which can be disposed in

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a truck 1 is moved to an excavated soil stock yard and stopped, and a mixture screen 8 supported on a loading bed 2 and a conveyor 9 under the sieve are lowered from the loading bed 2 to the ground 10. 2. Place the mixture screen 8 on the ground 1 below the tip of the mixture conveyor 7 as shown in FIG.
Under the screen 8 and a conveyor 9 under the sieve.
Facing the beginning of. Arm 1 in the middle of the conveyor 9 under the sieve
The front end is tilted upward while being supported by the wheels 1 and 11 and the wheels 12 (FIG. 3).

When the excavated earth mass is put on the roll screen 5 in this state, the excavated earth mass is transferred to the roll screen 5.
With the rotation of the roll 5 ′ (for example, a sieve having a size of 100 mm) and the flange 5 ″, the earth mass is broken and falls below the sieve having a size of 100 mm or less, and falls on the main conveyor 3. Roll back) and guide plate 1
Fall from 3 to the ground 10.

The sifted earth mass or soil contains a little water, swells with air during excavation, and swells and is transported forward by the main conveyor 3, while lime powder is supplied to the excavated soil from a lime powder feeder 6 on the way. In addition, the mixer 4
And the high-speed rotors 4a, 4a inside the mixer 4.
b, and the mixture is small mixed by the low-speed rotor 4c (FIG. 3), falls from the lower mixture conveyor 7 onto the vibrating mixing screen 8, and the under sieve is deposited on the ground (ground) 10 by the under-sieve discharge conveyor 9, and is sieved. Above is a mixture screen 8
From one side (the right side in FIG. 2).

As shown by the imaginary line in FIG. 2, the under-sieve discharge conveyor 9 can be directed to the right front, the slant right front, the right side, and the slant right rear of the truck 1. The conveyor 9 can be turned to the right rear by changing the direction. The screen 8 is disposed on the ground 10 on the left side of the loading platform 2 as shown by the imaginary line in FIG. 2 and is carried out by the conveyor 9 to the left front, diagonally left front, left side, diagonally left rear or left rear of the truck 1. Is possible.

[0010] The sieved material deposited as described above is loaded on an unloading truck, transported to a public construction site such as gas pipe burying work, and reused as backfill material.

Thereafter, the mixture screen 8 and the under-sieve discharge conveyor 9 are mounted on the loading platform 2 as shown in FIG. 1, and the truck 1 is operated and removed from the stockyard.
