Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a ridge shaping machine used for shaping the slope of a ridge.

(Prior Art) Conventionally, ridge slopes have been shaped using a power shovel.

However, with this power shovel, it is not possible to properly shape the ridge, and it is also inconvenient because it cannot perform soil removal work associated with ridge shaping.

On the other hand, as a loading shovel capable of carrying out earth removal work, there is one in which an earth removal plate is removably attached to the shovel body, as shown in Japanese Utility Model Application No. 50-157704.

(Problems that the invention aims to solve) However, even though a portion of this loading shovel may be used as a compaction plate, the shape of this loading shovel is not originally suitable for ridge shaping. When performing bucket work, it is necessary to attach a large number of bucket teeth to the tip of the shovel body, and when attaching a soil removal plate to the shovel body, the bucket teeth must be removed, so bucket work and earth removal are difficult. It is very troublesome to switch between tasks.

The purpose of this invention is to improve the shaping of ridge slopes by rolling compaction, and also to facilitate the switching to excavation and loading work using buckets associated with ridge shaping, earth removal on slopes and horizontal surfaces, and land leveling work. This aims to improve the efficiency of the entire ridge shaping work.

[Structure of the invention] (Means for solving the problems) The present invention is based on the lift arm 2 of the shovel loader 1.
A ridge shaping rolling plate 4 made of a flat plate is pivotally supported at the tip of the tilt link 3 via brackets 6 integrally provided on both left and right sides of the plate. A bucket 16 having bucket teeth 17 is integrally provided at the end of the pressure plate 4 on the side where the tilt link is attached, and an earth removal plate 21 is removably fitted from the bucket teeth 17 over the bucket recess. The plate 21 has a member integrally provided on the back side of the cutting edge 25 with a recess 26 into which each of the bucket teeth 17 fits.

(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. Rolling onto the slope,
Excavation and loading work will also be carried out using the bucket cart 16. When the earth removal plate 21 is installed, the earth removal plate 21 can be moved by sliding the compaction plate 4 along the ridge slope or along the horizontal plane.
Earth excavation, soil removal, and land leveling work will be carried out in accordance with 1. In that case, the bucket tooth 17 of the bucket 16 is inserted into the recess 26 on the back side of the cutting edge 25 of the soil removal plate 21.
It is stored in.

(Examples) Hereinafter, the present invention will be described in detail with reference to examples 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, side plate-like brackets 6, which are integrally protruded from both sides of the rolling plate 4 for ridge shaping, are supported via pin shafts 7 and 8 by the tip ends of the brackets.

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.

As shown in FIG. 2, the rolling pressure plate 4 is formed of a single flat steel plate, and the tilt link 3 is moved from the end (upper end) of the rolling pressure plate 4 on the moving side during work with the rolling surface as a reference. A bucket 16 made of a curved plate is integrally provided by welding or the like between the brackets 6 on both sides in the upper surface portion facing the mounting side. A large number of bucket teeth (hereinafter simply referred to as teeth) 17 protruding from the end (upper end) on the moving side of the rolling plate are integrally attached to the grounding portion of the bucket 16.

Further, as shown in FIG. 2, a soil removal plate 21 is removably fitted from the tooth 17 of the bucket 16 to the top of the bucket recess. This earth removal plate 21 has integrally mounted mounting plates 22 on both sides that fit on the outside of the bracket 6, and bolt insertion holes 23 bored at two places on each of the mounting plates 22 on both sides are inserted into the mounting plates 22 on both sides. The earth removal plate 21 is fixed by aligning it with the bolt insertion holes 24 drilled at two locations in the upper part of the bracket 6, inserting the bolts into the insertion holes 23 and 24, and tightening them with nuts. Note that on the back side of the cutting edge 25 of the earth removal plate 21, a member having a recess 26 that fits each tooth 17 of the bucket 16 is integrally provided, and when the earth removal plate is attached, each tooth 17 is inserted into the recess 26. Insert into.

Furthermore, as shown in this Figure 2, the bucket 1
Two types of level plates 27 and 28 are integrally provided on the back surface of the device. One level plate 27 has a level surface 29 for slope work at an angle of 45 degrees with respect to the rolling plate 4.
When the rolling plate 4 is at an angle of inclination of 45° with respect to the horizontal plane, its level surface 29 is horizontal, and if the operator performs the work while roughly checking that the level surface 29 is horizontal, rolling plate 4
can be maintained at approximately 45° to the horizontal plane. Further, the other level plate 28 is the rolling plate 4
has a horizontal work level surface 30 parallel to the
If the work is carried out while roughly confirming the horizontality of the level surface 30, the rolling plate 4 can also be kept approximately horizontal.

Further, as shown in FIG. 2, the shaft holes 31 of the bracket 6 to which the tilt link 3 is connected via the pin shaft 8 are provided at two locations, and the pin shaft 8 is held at two locations by the shaft holes 31 at these two locations. By changing the tilt amount, the tilt amount can be adjusted and changed.

Next, to explain the operation of this embodiment, as shown in FIG.
9, roll the rolling plate 4 onto the ridge slope 32 until it forms an angle of 45° with respect to the horizontal plane. That is, the tilt link 3 is strongly pushed out by the tilt cylinder 14, whose pushing action is stronger than its pulling action, and the rolling plate 4 is tilted up to 45 degrees with respect to the horizontal plane using the pin shaft 7 at the tip of the lift arm 2 as a fulcrum.
The rolling plate 4 rolls onto the ridge slope 32 and
2 is rolled and shaped.

Also, when working with the bucket 16,
The bolts inserted into the bolt insertion holes 23 and 24 are removed, the soil removal plate 21 is removed from the bucket 16, and the bucket 16 is used to perform excavation and loading operations that are typical of a shovel loader on a slope or horizontal surface.
At this time, when the soil is scraped off by the teeth 17 of the bucket 16, the soil is stored in the bucket 16, so that the scraped soil can be loaded into the transport vehicle as is.

In addition, the large convex portion 33 on the ridge slope is caused by the crawler track 3
Lift cylinder 1 while bringing cylinder 4 closer to the bottom of the ridge.
1 to raise the lift arm 2 and press the compaction plate 4.
The ridge is raised diagonally as shown in FIG. Excavate and shape the slope.

Further, at the upper part of the ridge slope, the rolling pressure plate 4 is rolled onto the slope by the force of both the lift arm 2 and the tilt link 3, and the slope is shaped. In this way, a ridge slope with a height of about 3 m can be shaped almost in a fixed position.

In addition, when carrying out soil removal and land leveling work on a horizontal surface such as a place continuous to the upper and lower ends of a ridge slope, the soil removal plate 21 is fitted into the bucket 16, and while looking at the level surface 30 of the level plate 28, the soil is compacted. The plate 4 is held horizontally and slid on the ground, and the soil removal plate 21 performs soil removal and ground leveling work when moving forward.

In addition, on a continuous horizontal plane at the lower end of the ridge slope 32, soil removal work is performed toward the ridge slope 32 using the earth removal plate 21, and the soil is scraped up onto the slope 32 by the earth removal plate 21, and then It is also possible to carry out continuous work using the soil removal plate 21 and the rolling plate 4, such as rolling the scooped up soil onto the slope 32 using the rolling plate 4.

As shown in FIG. 3, a bucket 35 is integrally provided between the brackets 6 on both sides by welding or the like not only at the upper part but also at the lower part of the back surface of the rolling plate 4, and this lower bucket 35 is also provided with a tooth. The earth removal plate 36 may be detachably attached to the front surface in the same way as the upper part. In this case, the protrusion 33 in FIG.

[Effect of idea]

According to the present invention, a ridge shaping pressure plate made of a flat plate is pivotally supported at the tip of the lift arm and tilt link of a shovel loader via brackets integrally provided on both left and right sides of the plate. A bucket with bucket teeth is integrally provided between the tilt link attachment side end of the compaction plate, and an earth removal plate is removably fitted from the bucket teeth to the bucket recess. The rolling plate can be freely manipulated by using the vehicle movement and the movement of the lift arm and tilt link, and the rolling plate made of a flat plate can perform good rolling shaping of ridge slopes. Excavation and loading work can be carried out using a bucket through the pressure plate, and when the earth removal plate is installed, by sliding this compaction plate along the ridge slope or along the horizontal surface, the earth removal plate can be used to remove dirt on the slope. It can perform earth excavation, earth removal on a horizontal surface, and land leveling work, improving the work efficiency of the entire ridge shaping work, which includes not only slope work but also horizontal work. In particular, when shaping a slope using a bucket, the removed soil can be directly loaded onto a transport vehicle, which also improves work efficiency. Furthermore, since the soil removal plate is removably fitted over the bucket tooth and the bucket recess, it is easy to change from the bucket to the soil removal plate, or from the earth removal plate to the bucket, depending on the application. There is no need to remove and replace these from the lift arm and tilt link, and the time and labor required for replacement can be reduced. In particular, this earth removal plate has a member integrally provided on the back side of the cutting edge with a recess that fits into each bucket tooth, so the bucket tooth can be easily changed to a cutting edge, and it can be used as a true cutting edge. It is possible to switch between bucket work and earth removal work.
This earth removal plate also enables tilting operations that are not possible with ordinary earth removal plates.
