I am trying.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. For ease of understanding, the same parts as in the conventional art are denoted by the same reference numerals.

1 to 3 show a backhoe for excavating sediment according to the present invention. FIG. 1 is a side view, FIG. 2 is a front view,
FIG. 3 is a plan view.

The excavated sediment transfer backhoe 1 according to the present embodiment shown in FIG. 1 is an improvement of the mini backhoe 10. As shown in the front view of FIG. 2, one side of the mini backhoe 10 serves as a transfer device. Equipped with a screw conveyor 2.

The arrangement of the screw conveyor 2 is shown in FIG.
Bracket 3 provided on the traveling portion 11 as shown in the plan view of FIG.
The inclined portion is attached by and the horizontal portion thereof is attached by being placed on or fixed to the soil discharging plate 4 of the backhoe.

As shown in FIGS. 1 and 2, the excavated earth and sand transfer backhoe 1 excavates the ground by operating the arm and boom 12, and the excavated earth and sand is sucked into a sand scraping apron 5 at the tip. The accumulated soil and sand from the sand scraping apron 5 is transferred to the rear transfer section 6 of the screw conveyor 2 which is arranged in an inclined shape, and the swing operation of the swing structure 13 and the loading operation of the arm / boom 12 are unnecessary. And is loaded on the rough terrain vehicle 14 located behind the excavated sediment transfer backhoe 1.

The omission of such an operation of "swivel → loading (excavation) → swirl" is combined with the continuous simple operation of "excavation → sucking" of the arm / boom 12, and particularly improves the efficiency of excavation work. Therefore, even if the initial cost for installing the screw conveyor 2 is required, there is no problem.

As shown in FIG. 4, the screw conveyor 2 is formed in an L shape, and the sand scraping apron 5 in the horizontal portion is connected to the rear transfer portion 6 which is inclined at a predetermined angle in an orthogonal state. The excavated sediment is continuously transferred.

As shown in the perspective view of FIG. 4 (a), the earth and sand apron 5 is provided with a sediment accumulating portion 7 and an opening 9 of an outer cylinder 8 at its base. A screw conveyor 16 operated by a motor 15 is arranged inside the.

On the other hand, the rear transfer section 6 is internally provided with a screw conveyor that cooperates with the screw conveyor 16 of the soil and sand scraping apron 5, and the excavated soil from the screw conveyor 16 is continuously transferred by a motor similar to the motor 15. Therefore, from the opening at the rear end, the rough terrain vehicle 14
Is being discharged.

In the above embodiment, as shown in FIG. 4 (b) in a state where FIG. 4 (a) is viewed in the direction of arrow b, the rotary shaft of the screw conveyor 16 in the earth and sand apron 5 and the screw conveyor in the rear transfer section 6 are shown. The rotation axis of the screw conveyor is coaxially crossed to ensure smooth continuity between the screw conveyors, but the form of the screw conveyor 2 is not limited to this.

FIG. 5 shows another embodiment of the screw conveyor 2. In the present embodiment, FIG.
As shown in (a) as a perspective view, the connection state of the soil scraping apron 5'and the rear transfer part 6'in the screw conveyor 2'is different from that of the above-mentioned embodiment, and the soil scraping apron 5 is attached to this. The shape of'is also different from the sand scraping apron 5.

The rotation axis of the screw conveyor 16 in the sand scraping apron 5'of the screw conveyor 2'and the rotation axis of the screw conveyor in the rear transfer section 6'are as shown in FIG. As shown in b), they are arranged so as not to intersect each other coaxially, and the excavated earth and sand from the earth and sand scraping apron 5 ′ is dropped from the screw conveyor 16 onto the screw conveyor installed in the rear transfer section 6 ′. The form ensures continuity between screw conveyors.

In order to secure this combined state and the horizontal state with respect to the ground, the earth and sand apron 5'has one side of the earth and sand accumulating portion 7'raised in accordance with the inclination of the earth and sand apron 5 '.

As described above, in the present embodiment, the excavated earth and sand transferred from the earth and sand scraping apron 5'by the screw conveyor 16 is transferred from the outer cylinder 8'to the rear transfer portion 6 '.
Since the excavated earth and sand received by the screw conveyor of the rear transfer section 6'is not in a compressed state because it is dropped onto the screw conveyor of No. 6, the transfer and operation of the screw conveyor are performed smoothly. .

Further, the excavated sediment transfer backhoe according to the present invention is not limited to the above-mentioned embodiment in the way of equipping the backhoe with the screw conveyor, and the embodiment shown in FIG. 6 can be adopted.

That is, in another embodiment of the excavated sediment transfer backhoe according to the present invention, as shown in the plan view of FIG.
The bracket 17 provided in FIG.

At this time, the screw conveyor 2 is swung by, for example, separating the sand scraping apron 5 of the screw conveyor 2 from the soil discharging plate 4 of the backhoe and disposing a necessary bracket between the swivel 13. It is configured so as to be rotatable together with 13.

In the case of the present embodiment, since the revolving unit 13 and the screw conveyor 2 can be simultaneously revolved as shown in the figure, the range for excavating the earth and sand while the backhoe is placed at a specific position is enlarged. It is possible to do this, and it has the effect of enabling earth and sand excavation while shortening the travel time.

As described above, the excavated sediment transfer backhoe according to the present invention is basically arranged on the backhoe that is not limited to the mini backhoe shown in the present embodiment and the tip portion mounted on the backhoe. Since it consists of a gravel scraping apron and a transfer device consisting of a rear transfer part that is connected to the gravel scraping apron, the excavation work efficiency can be improved by omitting the swinging of the arm / boom and the loading of sand in the excavation of the backhoe at a narrow space. Is improving.
