CONSTITUTION:Multiple grates 4 are provided on the bottom face of a main body 1, and the whole main body 1 is formed into a bucket shape. A discharging means is constituted of rotor plates 9, 9-1 provided at the preset distance from a shaft 7 and slitters 10, 10-1 provided to face slits 6 on the plates 9, 9-1. The main body 1 is inserted into the residual soil, clods are taken into a bucket, V-shaped plates 9, 9-1 are rotated in the rotation direction of the shaft 7 by the rotation of a hydraulic motor 11, and the clods are collected to the center. The clods are pulled to the grates 4 side by the rotation of the plates 9, 9-1 and the slitters 10, 10-1, and the clods are discharged from the slits 6. Impurities such as gravel are crushed by the slitters 10, 10-1 and discharged after the grain size is adjusted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a debris separator used for removing unusable foreign matters from the residual soil generated by construction work and making it recyclable as a roadbed material.

[0002]

2. Description of the Related Art The residual soil generated during construction work is mixed with sludge-like substances, clay with high water content, sand and stones, or concrete waste, gravel, asphalt mixture waste, wood chips, and other waste materials. Therefore, in order to make effective use of these, it is necessary to remove the above-mentioned waste materials from the residual soil. or,
As a removing machine, a cylindrical trommel having a mesh or a vibrating screen is generally used.

[0003]

Since the above-mentioned conventional apparatus is installed at a specific place, a transport machine is required in order to transfer a predetermined residual soil to its installation position, and the equipment cost is not only high. Or, after removing these impurities, the soil mass must be crushed to adjust the particle size. In use, after adjusting the particle size, it is necessary to add and mix an improving agent suitable for soil properties to obtain a ground material having the required strength. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a debris separator that enables efficient work and can be used as an attachment of a conventional backhoe for excavation.

[0004]

In order to achieve the above-mentioned object, the present invention has a drainage attached to the bottom surface of a bucket to form a plurality of slits, and the discharge functioning in accordance with the rotation of the shaft in the bucket. In the debris separator provided with the means, the discharging means includes the rotor plate 9 provided at a predetermined distance from the shaft 7 position, and the slitter 10 provided on the upper surface of the rotor plate corresponding to the slit 6 position.
And consisted of Therefore, the clod taken into the bucket is discharged from the slit of the rostrul by the rotor plate, but impurities such as gravel are crushed by the slitter, the particle size is adjusted, and then discharged.

Embodiments will be described below with reference to the drawings. Figure 1
[Fig. 2] is an overall perspective view of an embodiment of a debris classifying machine according to the present invention, as seen from the front side, and Fig. 2 is a perspective view as seen from the rear. In Figure 1, 1 is the earths and stone separator body has a pawl 3 to 2 and the tip side plates (side plate), which was to form a complete shape is provided a plurality of grate 4 as a bucket-like on the bottom surface is there. A plurality of bridges are bridged to the bottom of the grate with a reinforcing frame 5, and each grate 4 is fixed to the grate to reinforce the grate. Therefore, the bottom surface has a plurality of slits 6 divided by each of the stoves 4 and the reinforcing frame 5.
Is formed. Reference numeral 7 denotes a shaft which penetrates both side plates 2 and a rotor plate 9 is attached to an arm attachment plate 8 provided on the shaft. The rotor plate 9 has a V-shape in the rotation direction, and rotates along the same distance locus with respect to the shaft 7. Although not shown in FIG. 1, a rotor plate 9-1 having the same structure as that of 9 is provided at a position different in 180 ° rotation angle from FIG. 1 (see FIG. 2).

As shown in FIG. 1, every other slitter 10 is provided on the upper surface of the rotor plate 9 corresponding to each slit 6, and as shown in FIG.
9-1 is provided with a slitter 10-1 corresponding to the slit while the slitter provided on the rotor plate 9 cannot be covered. That is, when the shaft 7 makes one revolution, the slitter 10 shown in FIG. 1 first enters the corresponding slit, and then, at a position different by 180 °, the slitter 10-1 enters the remaining slit portion. Reference numeral 11 denotes a hydraulic motor, which connects the motor-side sprocket and the shaft-side sprocket 13 via a connecting means 12. FIG. 4 is a partially cut-away plan view showing the relationship between the slitter 10 and the lost body 4, in which the mounting position of the slitter 10 is twisted with respect to the traveling direction (arrow) of the rotor plate 9.

Next, the operation will be described. The main body 1 is used by being attached to a backhoe for excavation. First, the main body 1 is inserted into the remaining soil, and the clods and the like are taken into the bucket.
In this case, the rotation of the hydraulic motor 11 causes the rotor plates 9 and 9-1 to rotate together with the shaft 7. As described above, the rotor plates 9 and 9-1 are V-shaped with respect to the rotation direction, so that the set of soil masses has a screw effect that concentrates them in the center, so that unnecessary soil pressure is not applied to the side plates 2 and 2. It is like this. The set of soil blocks taken in here is the rotor plate 9, 9-1
And the rotation of the slitters 10 and 10-1 pushes it toward the rustle side and discharges it from the slit 6. At this time, the slitter is crushed by the asphalt mixture having a sufficient strength or the one having a low compressive strength by meshing with the grate. Further, since the slitter has a mounting strength, a flat and slender object is twisted and crushed when it collides with the slitter.

The width W0 of the slitter is W
Since it is smaller than 1 (Fig. 4), it is possible to very easily remove the debris and the like adhering between the grate. Further, as shown in FIG. 3, since the rotation locus of the slitter passes outside the outer peripheral edge of the throttle between the reinforcing frames 5 and 5, an unreasonable force is required to dislodge the clod of clogging between the rostruls. Can be done without. Therefore, the only thing that has passed through the rostr is the one after crushing, and it can be obtained as a particle size-adjusted one. Further, when gravel or concrete pieces are caught during the crushing, they can be easily removed by rotating in the reverse direction. Further, in the present application, it has been described that two sets of slitters are provided every other slit and the slitters are alternately inserted into the slits, but the present invention is not limited to this, and it corresponds to all slits from the beginning. Then, a slitter may be provided.

[0009]

As described above, according to the present invention, a plurality of slits are provided on the bottom surface of the bucket body by a roast, a rotor plate that rotates with the shaft is provided, and a plurality of slitters are attached to the rotor plate. Since the rotor plate is rotated together with the rotor plate, it can be applied to a wide range of target soils from liquids with high water content to highly soiled peat soils as well as clogging of the rustles.
