[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an attachment for a turf that is used by being attached to a bucket of a power shovel.

[0002]

2. Description of the Related Art Conventionally, it has been necessary to plant grass on straight slopes at predetermined intervals on river slopes and road slopes at precise positions (hereinafter referred to as "muscle grass construction"). A method of constructing this line grass will be described with reference to FIG. First,
A base surface 11 having a predetermined slope using the power shovel 10.
To form. While forming the clothing soil layer 12 with a thickness of about 30 cm on the surface of the foundation surface 11, the lawn 13 is planted, but the work is started from the lower end of the slope 14 and a necessary amount of soil is appropriately added. While using a scoop, set one side 15 of the groove for inserting the grass 13 in the vertical direction about 15
Form to a depth of cm. At this time, it is necessary to preliminarily stretch a thread on the lawn surface of the slope 14 and form the one side surface 15 of the groove at an accurate position along the thread. Then, the mat-shaped turf 13 is put along the one side surface 15 of the groove, and the soil is piled up and fixed.
Then, the clothing soil layer 12 is erected to be appropriately hardened, and the turf is planted one after another while finishing the slope 14 at a predetermined slope.

[0003]

Although heavy equipment such as power shovels are used in the construction of the above-mentioned turf,
Since it is difficult for the power shovel to move on rough terrain and the bucket cannot rotate about the axis perpendicular to the ground surface at the tip of the boom, it is difficult to accurately position the bucket on the turf insertion planned line. It is not used for the work of forming the lawn insert groove, but only carries the work of carrying soil to its vicinity. Therefore, since most of the work is done manually, it is hard work and it is difficult to improve work efficiency. Also, from the social background of the shortage of civil engineering workers and the aging of society, there is a demand for facilitating the construction of muscles, reducing the burden on workers, and increasing their efficiency.

Therefore, in the present invention, it is a technical problem to be solved to provide an attachment for a turf which is mounted on a bucket of a power shovel and which can form a turf insertion groove on the ground surface in a linear streak shape by the power shovel. It is what

[0005]

A technical means for solving the above-mentioned problems is to provide a support for a muscle turf attached to a bucket of a power shovel and to support the support on the bucket. A knife portion having a substantially flat blade edge on the formed shaft portion is rotatably provided while protruding from the bucket.

[0006]

[Operation] For example, when constructing a turf on a river embankment or on the slope of a road, operate a power shovel equipped with a turf attachment on the bucket to move the knife part of the attachment from the cutting edge to the ground at the required position. To form a grass-grooving groove. At this time, in a state immediately before the blade edge of the knife portion is pressed down into the ground, the operator can easily rotate the knife portion to align the blade edge with the planned grass insertion line. The groove can be formed at an accurate position.

[0007]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a front view of the attachment for muscle turf, and FIG. 2 is a sectional view taken along the line AA. In both figures, a bearing 2 is attached to a bucket 1 of a power shovel. The bearing portion 2 constitutes a support portion in the present invention, and is composed of a cylindrical pipe into which the rotating shaft 3 is inserted, and the pipe is located at a position slightly inward from the center of the tip end portion 1 a of the bucket 1. It is provided in a direction perpendicular to the inner wall surface of No. 1 and at the edge of the tip portion 1a, and is welded to the inner wall surface. The rotating shaft 3 pivotally supported by the bearing portion 2 is a columnar shaft, is erected at the center of the upper surface of the receiving plate 4, and has a hole formed at the upper end of the rotating shaft 3. A female screw 3a is screwed onto the female screw 3a, and a cap 5 for preventing the screw from coming off is screwed onto the female screw 3a. The cap 5 for preventing coming off is the bearing 2
A male-threaded portion 5b which can be screwed into the female screw 3a is vertically provided on a disk-shaped collar 5a having substantially the same outer diameter as the above. In addition,
The short pipe 2a loosely fitted to the rotation shaft 3 is a cylindrical pipe having substantially the same inner and outer diameters as the bearing portion 2, and is a spacer for smoothing the rotation of the rotation shaft 3.

The receiving plate 4 is a rectangular steel plate having a width substantially the same as that of the tip 1a of the bucket 1,
A ridge portion 6b of the knife portion 6 is attached to the central portion of the lower surface of the steel plate in the longitudinal direction. This knife part 6 is a bucket 1
A rectangular parallelepiped having a length substantially the same as the width of the opening, and as shown in the drawing, a substantially flat blade edge 6a is formed thin toward the tip and relatively sharp. Then, the triangular reinforcing plate 4a is welded to the receiving plate 4 and the side surface of the knife portion 6 to support the knife portion 6 in a vertical state with respect to the receiving plate 4. Also,
From both left and right ends of the receiving plate 4, an operating rod 4b made of equilateral angle steel is extended in the longitudinal direction.

As described above, the attachment for muscle grass attached to the bucket 1 has the flange 5a of the cap 5 on the upper end of the bearing portion 2 in a state where the blade edge 6a is substantially downward (a state shown in FIG. 2). While abutting, the knife portion 6 is supported by the cap 5 via the rotating shaft 3. Since a gap is formed between the tip end portion 1a of the bucket 1 and the upper surface of the receiving plate 4 and between the lower end of the bearing portion 2 and the upper end of the short pipe 2a, respectively.
The knife portion 6 can be rotated around the rotation shaft 3.
As will be described later, when the power shovel is operated and the knife portion 6 is pressed down from the cutting edge 6a into the ground, the tip portion 1a of the bucket 1 vertically contacts the upper surface of the receiving plate 4 and the knife portion 6 A pressing force is applied to the ridge 6b. At this time, as shown in FIG. 2, since the receiving plate 4 is formed in a wide rectangular shape, the knife portion 6 rotates about the rotating shaft 3 with respect to the bucket 1 within a predetermined angle range. However, the tip portion 1a does not come off from the upper surface of the receiving plate 4, and a stable pressing force can be transmitted to the blade edge 6a.

Next, the case where the attachment for muscle grass is removed from the bucket 1 and used as a normal power shovel will be described. FIG. 3 is a cross-sectional view of the essential parts showing a state in which the attachment for muscle grass has been removed from the bucket 1 and the soil intrusion prevention pipe 7 has been attached. In the figure, the dirt intrusion prevention pipe 7 is an insertion pipe 7a that can be inserted into the bearing portion 2.
A disk-shaped lid 7 having the same outer diameter as the outer diameter of the bearing 2 is provided at the lower end of the
b is attached and can be further fixed to the bearing 7 by a bolt 7c. Therefore, by mounting the soil intrusion prevention pipe 7 in place of the rotating shaft 3 on the bearing portion 2 of the bucket 1, the opening portion of the bearing portion 2 can be closed and the inside thereof can be protected. Can be used as a power shovel almost in the same manner as.

Next, a method of constructing a muscle turf using the attachment for muscle turf according to the present invention will be described. FIG. 4 is a cross-sectional view of the slope of the river embankment before the lawn is inserted, FIG. 5 is a cross-sectional view of the slope while the lawn is inserted, and FIG. 6 is a cross-sectional view of the slope explaining the work after the lawn is inserted. is there. As shown in FIG. 4, a power shovel 10 is used to form a base surface 11 having a predetermined slope on the slope of the river embankment, and the foundation surface 11 is covered with a soil layer 12. Next, the back surface of the bucket 1 is used for erection to appropriately harden the clothing soil layer 12. At this time, 50% of the construction
The preliminary surface 14a parallel to the slope 14 is formed at a stage before finishing to the final shape (the thickness of the clothing soil layer 12 is about 30 cm in this embodiment) until the preliminary surface 14a.
Thread a thread (not shown) on the line where the grass will be put.

Next, as shown in FIG. 5, the power shovel 10 in which the attachment for muscle grass is mounted on the bucket 1 is operated to adjust the receiving plate 4 to be in parallel with the preliminary surface 14a, and the knife portion 6 The cutting edge 6a is aligned with the position aligned with the thread. At this time, the operator on the spare surface 14a operates the operating rod 4b while watching the parallel state of the receiving plate 4 and the spare surface 14a, thereby rotating the knife portion 6 in the direction perpendicular to the blade and cutting edge 6a. It is easy to align the yarn with the yarn in a correct posture in a state of being perpendicular to the preliminary surface 14a. Then, the bucket 1 keeps the receiving plate 4 in parallel with the preliminary surface 14a while the knife portion 6 is moved to the preliminary surface 14a.
It is pressed down to a and is sunk into the ground to a desired depth to form a groove 14b. After that, the work of inserting the mat-shaped turf 13 into the groove 14b can be performed very easily. In addition, the spare surface 14a is the groove 14
The surface 14c is slightly raised due to the formation of b. Further, if the power shovel 10 tilts in the front-back direction on an irregular ground, the bucket 1 also tilts in the front-back direction accordingly, so that the left and right ends of the blade edge 6a do not contact the reserve surface 14a at the same time on the grass insertion planned line. But also in this case
The knife portion 6 has a distance between the ridge portion 6b and the cutting edge 6a (see FIG. 2).
Since it is made sufficiently large, it can be used only by appropriately adjusting the press-fitting depth of the knife portion 6, which is highly practical.

Thus, with the grass 13 in the groove 14b, the surface 14c of the soil layer 12 is erected using the back surface of the bucket 1 as shown in FIG. Then, the slope 14 is finally shaped into a predetermined shape.

Depending on the nature of the soil of the clothing soil layer 12, the water content, etc., the soil may adhere to the knife portion 6 of the attachment for muscle grass, and the workability may be significantly impaired. In this case, a vinyl sheet having a large tensile strength cut into a required size is laid on the preliminary surface 14a, and the knife portion 6 is pressed down to form a groove, and then the vinyl is removed. Good. In this way, even when the soil of the clothing soil layer 12 is in a bad condition, it is possible to easily align the blade edge 6a of the knife portion 6 with the planned grass insertion line,
It is possible to improve the construction efficiency of the muscle grass.

[0015]

As described above, according to the present invention, it is possible to easily form the straight grass-like grass-grooving grooves on the ground surface by the power shovel having the attachment for the muscle grass attached to the bucket. Work efficiency can be improved. Further, since the process which has conventionally required manual labor in the construction of the muscle turf can be mechanized, there is an effect that the burden on the operator can be reduced.
