(Function) In the present invention, the rolling plate 4 is raised to a predetermined height by the lift arm 2, and by the pressing action of the tilt link 3, the rolling plate 4 is rotated about the shaft support of the lift arm 2 as a fulcrum, and the ridge is raised. Roll pressure onto the slope. Further, by moving the rolling plate 4 along the ridge slope from top to bottom or from bottom to top, the upper or lower tooth 21 cuts and shapes the convex portion of the ridge slope.

[Example of idea]

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

As shown in FIG. 1, a lift arm 2 and a tilt link 3 of a truck type shovel loader 1 are shown.
Instead of the original bucket, brackets 5 and 6, which are integrally protruded from the rolling plate 4 for ridge shaping, are supported via shafts 7 and 8 by the tip of the bracket.

The lift arm 2 is moved up and down by a lift cylinder 11 around a support shaft 12, and is also moved up and down by a tilt link 3.
is connected to the lift arm 2 via the tilt lever 13, and the tilt lever 13 is connected to the tilt cylinder 14.
The tilt link 3 is moved forward and backward by rotating around the support shaft 15.

In addition, as shown in FIG. 1, the rolling pressure plate 4
triangular side plates 16 are integrally protruded from both ends of the , and a rolling plate 4 is mounted on the upper part of one of the side plates 16.
A level plate 18 having a level surface 17 for inclination at an angle of 45 degrees is integrally provided. Therefore, when the rolling plate 4 is at an angle of inclination of 45° with respect to the horizontal plane,
The level surface 17 of the level plate 18 is horizontal, and if the operator performs the work while roughly confirming the horizontality of the level surface 17, the rolling plate 4 can be maintained at approximately 45 degrees with respect to the horizontal surface.
In addition, a level plate (not shown) having a horizontal level surface parallel to the rolling plate 4 is integrally provided on the top of the other side plate 16, and the horizontal level surface of this level plate is made horizontal. This allows the rolling plate to be kept horizontal.

As shown in FIG. 2, the rolling plate 4 is formed from a single flat steel plate, and teeth 21 are removably provided on the upper and lower parts of the rolling plate 4.

As shown in FIG. 3, the teeth 21 are installed by welding a mounting plate 22 to the back surface of the rolling plate 4, fitting the grooves 23 of the teeth 21 into the mounting plate 22, and then The tightening part 24 on one side is brought into close contact with the mounting plate 22, and the bolt 26 is inserted from the rolling surface 25 of the rolling pressure plate 4 into the holes of the rolling pressure plate 4, the mounting plate 22, and the tightening part 24, and the nut is screwed into the bolt 26. 27 fixes the fastening portion 24 on one side to the mounting plate 22. i.e. Tooth 2
Fix 1 by tightening it unevenly. The rolling side surface 28 of the tooth 21 is formed flush with the rolling surface 25 of the rolling plate 4, and the head 29 of the bolt 26 is formed flush with the rolling surface 25 of the rolling plate 4.
is inserted into the recess 30 of the rolling plate 4 so that the protrusion does not protrude into the rolling surface 25 of the rolling plate 4 in any way. In this way, one surface 28 of the tooth 21 is connected to the rolling surface 2 of the rolling pressure plate 4.
By making it flush with 5, the rolling slope of the ridge can be shaped into a smooth flat surface.

Next, to explain the effect, as shown in Figure 4,
The soil 33 on the ground is scraped up to the bottom of the ridge by the compaction plate 4 set at 45 degrees with respect to the horizontal plane.
As shown in FIG. 5, the soil is pressed onto the lower part of the ridge to form a 45° foundation slope 34. Further, the cover belt 35 is brought closer to the lower part of the ridge and the lift cylinder 11 is
The lift arm 2 is raised to raise the rolling pressure plate 4 to a predetermined height, and the tilt link 3 is strongly pushed out by the tilt cylinder 14 whose pushing action is stronger than the pulling action, and the rolling rolling plate 4 is raised to the lift arm 2. is tilted up to 45 degrees with respect to the horizontal plane using the shaft 7 at the tip as a fulcrum, and the rolling plate 4 is rolled onto the ridge slope, thereby shaping the slope. Note that at the upper part of the ridge slope, rolling pressure can be applied by the forces of both the lift arm 2 and the tilt link 3.

Further, the large convex portion 36 on the slope of the ridge can be formed by moving the rolling plate 4 shown in solid line in FIG.
6, or by moving the compaction plate 4 shown by the two-dot chain line in FIG. do. In this way, height 3
It is possible to shape the slope of a ridge approximately 100 m in length almost in a fixed position.
Further, the teeth 21 of the rolling plate 4 may be used to level the ground.

[Effect of idea]

According to the present invention, since the rolling plate for ridge shaping is pivotally supported by the tip of the lift arm and tilt link of the shovel loader, the rolling plate is positioned in front of the operator.
Not only is it easy to operate, it also improves work accuracy. In addition, the conventional power shovel used to press the entire surface when shaping ridges has been replaced with a power shovel.
In the present invention, by using the tilt operation force of the shovel loader, the rolling plate can be powerfully rolled onto the ridge slope using the shaft support provided by the lift arm as the fulcrum. Furthermore, the present invention fixes a mounting plate to the upper and lower non-rolling surfaces of the rolling plate, a part of this mounting plate protrudes from the rolling plate, and a cut is made in the protruding part of the mounting plate to the rear of the tooth. Fit the formed concave grooves, make the rolling side surface of the tooth flush with the rolling surface of the rolling plate, and tighten the tightening part protruding onto the mounting plate from the non-rolling side of the tooth with a bolt and nut. Since it is fixed to the mounting plate, by fitting the protruding portion of the mounting plate into the recessed groove of the tooth, it is possible to compensate for the insufficient mounting strength of partial tightening in which only the tightening portion of the tooth is tightened with bolts.
Then, by moving the compaction plate along the ridge slope, the convex part of the ridge slope can be strongly cut and shaped using the upper or lower tooth, and the surface on the rolling side of the teeth and the rolling surface of the compaction plate can be strongly shaped. Since the surfaces are flush with each other, there are no recesses on the rolled ridge slope, resulting in a flat finish. Since these teeth are attached with bolts and nuts, they can be easily replaced if they become damaged or worn. Furthermore, the ridge shaping machine of the present invention can be constructed extremely simply by simply providing a compaction plate instead of a bucket as an attachment for an existing shovel loader, so it is not expensive and there is no concern about the straightness of the vehicle.
