Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a compaction finishing device used in civil engineering work.

(Prior Art) In civil engineering work, it is often necessary to compact the earthwork glue surface. For example, this applies to shaping and compacting the surface of a road construction embankment, shaping and finishing a floor surface for installing concrete block frames, and shaping and compacting colomo soil when installing striated turf on the embankment surface.

Conventionally, a mechanical construction method has been known for shaping and compacting clayey soil by pressing it with a bucket attached to a bucket. However, this mechanical construction method cannot be applied to sandy or silty soils because it cannot be compacted even by pressing the paste surface bucket, so manual construction using clay panels is relied upon.

(Problems to be Solved by the Invention) In the conventional glue surface compaction method, mechanical construction methods cannot be applied to the glue surface of sandy soil or silty soil, and manual construction using clay panels is relied upon. For this reason, a great deal of effort and time is spent on the work.
Combined with the recent labor shortage, this has become a serious problem.

(Means for Solving the Problems) The compaction finishing device of the present invention includes a backhoe, a bucket held at the tip of an arm of the backhoe, and having a top plate that can be opened and closed;
A vibrating compactor is provided at the tip of the arm, facing the top plate of the bucket, so as to be rotatable back and forth and to the left and right, and to be translatable up and down via parallel links.

Hereinafter, the operation of the present invention will be explained in detail together with examples.

(Example) Fig. 1 is a side view showing the overall configuration of a compaction finishing device according to an embodiment of the present invention, Fig. 2 is a front view of a vibrating compaction machine and a bucket located behind it, and Fig. The figure is a sectional view taken along line A-A' in FIG.
For convenience of explanation, orthogonal coordinates X, as shown in FIG.
Y and Z are set.

In Figures 1 to 3, 1 is a backhoe;
2 is a fixture, 3 is a bucket device, and 4 is a vibratory compaction unit consisting of a vibratory compaction machine and its holding mechanism.

As the backhoe 1, a general-purpose commercial product is used as is. The backhoe 1 is comprised of a main body part 1a which is equipped with a remote control mechanism for each part of the compaction finishing apparatus and which can move forward and backward, and a bendable arm part 1b which projects forward of the main body part 1a. A bucket device 3 and a vibrating compaction unit 4 are connected to the tip of the arm portion 1b of the bucket hoe via an attachment 2.
is installed.

The bucket device 3 is a main body portion 3 that scoops out soil and sand.
a and a top plate 3b which can be opened and closed when supplying the scooped earth and sand to the vibration compaction machine 4. The main body part 3a of the bucket bag is composed of a bottom plate and both side plates, and preferably has a triangular shape. Top plate 3b
corresponds to that of a general-purpose bucket bag with a top plate, and a pin mounting base 3c is fixed to the front left and right ends, and a pin mounting base 3e is fixed to the front center part. The pin mounting base 3c fixed to the left and right ends of the top plate 3b is connected to the pin 3d and the hydraulic cylinder 3.
This is for attaching f. A hydraulic cylinder 3f opens and closes the space between the bucket main body 3a and the top plate 3b around a pin 3d.

The pin mounting base 3e consists of a pin 3h, a sector-shaped internal gear 3k, and a receiving plate for the mounting tool 2.
It is fixed to the front center part of b. hydraulic cylinder 3
f are arranged on both sides of the top plate 3b for opening and closing the bucket main body 3a and the top plate 3b. The H-type frame 3g and the H-type frame 4e are arranged parallel to each other and laterally (X-
(within the Y plane). The lower end of one H-shaped frame 3g is rotatably attached to a pin mount 3e via a pin 3h, and a hydraulic motor 3 with a reducer is attached to its upper end.
A small gear 3j rotated by i is attached. This pinion 3j is a fan-shaped internal gear 3k
The small gear 3j is rotated by the hydraulic motor 3i with a speed reducer.
The mold frame 3g moves back and forth around the pin 3h (Y-
(in the Z plane).

The vibration compaction unit 4 includes a vibration compaction machine consisting of a boat-shaped compaction plate 4a and an exciter 4b, a pin mounting table 3e, H-shaped frames 3g and 4e, four parallel links 4f, an L-shaped frame 4d, and these. It is comprised of a holding mechanism which is made up of pins that connect each other and holds the vibrating compaction machine on the fixture 2 so that it can rotate back and forth, left and right, and can translate up and down. This vibrating compaction section performs compaction by vibrating the boat-shaped rolling compaction plate 4a with a vibrator 4b while leveling the earth and sand supplied from the bucket device 3 with a scraper. The vibration compaction machine can be rotated left and right (around the Z axis) over a predetermined angular range by a torque actuator 4h attached to the front center of the frames 3g and 4e that make up the H-shaped frame. be.

The vibratory compaction machine is mounted so that it can be translated up and down by a parallel linkage mechanism. Boat-shaped compaction plate 4
a is elastically supported by an L-shaped frame 4d with four vibration damping rubbers 4c interposed therebetween, and a boat-shaped rolling pressure plate 4
It is caused to vibrate up and down by a vibrator 4b fixed to the central lower part of the a. The vibrator 4b is fixed to the bottom plate of the boat-shaped rolling plate 4a, and generates vibration force by a hydraulic motor driven by hydraulic power supplied from the backhoe 1.

The L-shaped frame 4d has an L-shaped lateral shape and a gate-shaped rigid frame structure in front, and its lower part is fixed to the bottom plate, and supports the boat-shaped rolling plate 4a via vibration damping rubber 4c at the four corners of the lower part. Parallel links 4f are attached at four upper and lower locations by pins 4g. One frame 4 that makes up the H-shaped frame
e has an H-shaped front view, and pin mounting bases having pin holes for mounting parallel links 4f are fixed on both left and right sides, and a torque actuator 4h is mounted at the center of the front. Since the bearing portion of the H-shaped frame 3g is press-fitted into the shaft end of the torque actuator 4h, the H-shaped frame 4e and the H-shaped frame 3g are rotatable in the left-right direction.

The parallel link 4f, the L-shaped frame 4d, and the H-shaped frame 4e are rotatably connected via a pin 4g. The L-shaped frame 4d translates vertically with respect to the frame 4e via a total of four parallel links 4f arranged vertically and horizontally. The stoppers 4i are fixed to pin mounts at the left and right ends of the H-shaped frame 4e, and are used to limit the inclination range of the parallel link 4f, and therefore the vertical translation range of the boat-shaped rolling plate 4a.

Figure 4 A and B show the bucket main body 3a and the top plate 3.
b shows how the hydraulic cylinder 3f performs an opening/closing operation centering on the pin 3d of the pin mounting base 3c.

Figure 5 A and B are hydraulic motor 3i with reducer.
As the pinion 3j rotates, the pinion 3j moves along the direction of extension of the fan-shaped internal gear 3k, causing the frame 3g to rotate back and forth (around the X axis) around the pin 3h. It shows the situation.

FIGS. 6A and 6B show that even if the fixture 2 and the bucket device 3 move upward, the L-shaped frame 4d remains on the parallel link 4 until it is stopped by the stopper 4i.
By tilting with respect to the link 3g via f and the pin 4g, the boat-shaped compaction plate 4a of the vibrating compaction machine is
This shows how the adhesive remains in close contact with the paste surface.

Note that the scraper 4j has an L-shaped frame 4d.
It is installed so that it can be adjusted in the vertical direction on the top surface of the bucket side, and is used to adjust the amount of compacted soil supplied from the bucket device 3 and uniformly supply it to the vibratory compaction surface. .

Although the compaction finishing device of the present invention has been described above, taking as an example the case where the compaction finishing device of the present invention is applied to a glued surface, the scope of application of the compaction finishing device of the present invention is not limited to only a glued surface. In other words, by using a bucket hoe as a self-propelled mechanism and a bucket device as a compaction soil supply mechanism, it is possible to reduce the small capacity of vibration compaction of horizontal roadbeds, which is currently carried out by workers while walking. The compaction finishing device of the present invention can be utilized as an alternative to plate compactors.

(Effects of the Invention) As explained in detail above, the compaction finishing device of the present invention has a configuration in which the bucket device and the vibrating compaction machine are integrally attached to the tip of the arm of the bucket, so that the compaction finishing device of the present invention can finish the compaction with one machine. It becomes possible to excavate and compact the surface.

In addition, the compaction finishing device of the present invention adopts a compaction method using vibration, so it can be applied to the surface of any soil type, such as clay soil, sandy soil, silty soil, etc., using a completely mechanical method. This makes it possible to significantly reduce work effort and time.

Furthermore, since the compaction finishing device of the present invention uses a bucket device whose top plate can be opened and closed,
The amount of earth and sand to be compacted can be adjusted and supplied to the finished surface, greatly improving work efficiency and achieving a good finish.

In addition, the compaction finishing device of the present invention has a structure in which the vibrating compaction machine is held at the tip of the arm so that it can rotate back and forth, left and right, and can translate up and down via a parallel link. This makes it possible to bring the material into close contact with surfaces to be finished, such as surfaces, which greatly improves compaction efficiency and provides a good finish.
