DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to embodiments. As shown in FIG. 1, a pick-up bucket a attached to a claw portion (described later) of a ripper attachment A is a left bucket body 1 and a right bucket body 2. And the bucket body 1 on the left side is shown in FIG.
Required height (approx. 280 mm), as shown in Figure (a)
And a back plate 3 having a required length (about 1850 mm) and side plates 4 forming an L-shape with the back plate 3 at both longitudinal ends of the back plate 3.
A stay 5 for joining the upper surface of each side plate 4 and the upper surface of the back plate 3, a pair of mounting plates 6 projecting at intervals on the inner surface of the central portion of the back plate 3 in the longitudinal direction, and the upper and lower parts of the mounting plate 6. As shown in FIG. 3 (a), the back plate 3 is provided with a bolt hole 7 penetrating therethrough. Then, a rib 10 having a convex shape is provided laterally toward the inner surface along the longitudinal direction. As shown in FIG. 2 (b), the bucket body 2 on the right side has a back plate 3, side plates 4 at both ends forming an inverted L-shape together with the back plate 3, and a stay 5. In the same manner, the pair of mounting plates 6 are provided so as to be wider than the space between the mounting plates 6 of the left bucket body 1. Ribs 9 provided above and below the back plate 3
Can be replaced with a round pipe, as shown in FIG. 3 (b).

The lifting bucket a thus constructed
In the bucket body 2 on the right side, as shown in the partial diagram (a) of FIG. 4, the ripper body 11 of the ripper attachment A is
Shaft insertion hole 1 penetrating two upper and lower parts of each of the three claws 12
3 and a bolt hole 7 penetrating through a pair of mounting plates 6 protruding from the back plate 3, a long large-diameter bolt 14 is inserted, and between the front and rear claw portions 12 and each mounting plate 6. The collar 15 is externally fitted to the bolt 14 of, and the nut 16 is attached from the outer surface of the one mounting plate 6.
Tighten and tighten. Even in the bucket body 1 on the left side,
As shown in the partial diagram (b) of FIG.
A bolt 18 shorter than the bolt 14 is inserted through the shaft insertion hole 13 penetrating up and down of each claw portion 12 of the book and the bolt hole 7 penetrating the mounting plate 6 of the back plate 3, and a similar collar 15 is inserted. It is fitted on the outside and tightened with the nut 16. Therefore, as shown in FIG. 1, the pick-up bucket a has right and left bucket bodies 2 and 1 attached to the ripper body 11 and the pressing ripper 17 of the ripper attachment A through the shaft insertion hole 13 and the bolt 14, respectively. It is provided as both gripping buckets b of the backhoe joined at 18.

As shown in FIG. 6, the both-holding buckets b of the backhoe are booms 20 from which the soil and humus accumulated on the bottom of the agricultural waterway 19 are opened in the V-shape of the two bucket bodies 1, 2. Is operated to lower the arm 21 while lowering the rod 23 of the hydraulic cylinder 22 to operate the ripper body 11 and the pressing ripper 17 via the link mechanism 24,
As shown in FIG. 5, since the scooping operation is not required just by joining the ends of the two bucket bodies 1 and 2 to the vertical edge 25 of the pulling side plate 4, the arm 21 of the backhoe B and the hydraulic cylinder 22 on the arm 21 are not required. The operation is simple, and the soil and the like are picked up by both the bucket bodies 1 and 2 by the operation and carried out to the outside of the water channel. In this case, since both bucket bodies 1 and 2 are long in the flowing direction of the water channel, the work of picking up soil and the like becomes efficient, and is also used for treating compost and soil in the field.

[0009]

EFFECTS OF THE INVENTION According to the present invention, there is an effect that it is possible to improve the work efficiency of the maintenance by the bottom roughness of the water channels such as the water channels for agriculture and the movement treatment of the compost and the soil.
