Description

EARTH MOVING, FILLING, COMPACTION,
THRESHING, PULLING OUT, FOR MOUNTING ON A HYDRAULIC SHOVEL
The present invention relates to a single public works apparatus capable of performing numerous tasks without any dismantling such as digging, compacting, backfilling, beating, tearing, cutting asphalt; all with permanent vibration available.

In the prior art, most of these operations were carried out by different equipment. Changing equipment costs a lot of time. For example, using 2 shovels on a sanitation site was not valid because there was no tool capable of compacting and backfilling. It was necessary to proceed in stages and to frequently change equipment, bucket to compactor and vice versa.

The present invention therefore aims to allow for example on sanitation sites to fulfill these functions with a single lage tool, the vibrating bucket, threshing operations, tearing from the sheet pile, backfilling and compacting the trenches, compacting by successive vertical pressure, embankment or continuous translation. With the addition of additional tools, we will also carry out continuous backfilling, cutting of asphalt, etc.

In this way a pipe laying team can be further mechanized to the maximum by a shovel assigned to earthworks, a second shovel assigned to backfilling, compaction, uprooting, transport and laying of pipes. Personnel other than the driver will be reduced to their simplest form.

This earthmoving, compacting, backfilling, threshing, hauling, cutting device will mainly consist of a vibrate; and a bucket (6 and also hooks
In the present invention, there will be in common between all the embodiments, dampers between the shovel and the vibrating bucket.

The vibrator vibrates the entire bucket. Several embodiments are possible: 10) the vibrator is an integral part of the bucket 20) the vibrator is separable from the bucket to be used for other uses.

The bucket can be bolted to the vibrator.

30) the bucket may be provided with teeth depending on whether it is to be used for earthworks on hard soil.

The bucket will be flat-bottomed to obtain a clean treks compaction.

For a good understanding the different figures will give an idea of some of the embodiments.

Figure 1 shows a bucket (1) in which the vibrator (4) has been fixed permanently. This bucket with its teeth (2) is more particularly intended for digging in hard soils under vibration. I1 can also compact with the face (5). The housing (3) is the one that receives the bucket attachment with shock absorbers that you will see precisely in Figure 2.

Figure 2 shows on the one hand a cup (6) provided with a recess (8) forming housing and protection of fixing holes (7) on the other hand a plate t (10) provided with holes (15) corresponding to the holes (7) on this plate are fixed supports (9) to which are connected the shock absorbers (11) which support a kind of U (13) supporting the fixing holes (12) of the axes of the shovel arm. The interchangeable bucket can be of a size, shape and size appropriate to the task. Rigidly linked together, in this case by bolting, the vibrating block and the bucket become one-piece. The hook (16) will allow the extraction of materials under vibration. The hydraulic supply (14) can come from the excavator.

Figures 3 and 4 show another principle in which a compactor (20) and a bucket (17) pivoting about an axis (19) are used. In work, as shown in the drawing, the bucket (17) comes below the compacting plate forming a housing for maneuvering the earth, a latch (18) blocks the bucket (17) in position.

When the backfilling operation is finished, the bucket (17) is retracted by rotating it around its axis either mechanically by locking (18) (Fig. 3) or completely hydraulically, controlled from the shovel by a jack (21) ( Fig. 4).

Figure 5 shows a bucket (23) mounted under the compaction plate (22).

The bucket can either be dismantled or used as a compactor with its flat bottom (26).

Figure 6 shows the bucket (24) mounted directly on the vibrator (25).

Figures 7 and 8 show a rotation system (26) for
put the bucket in the hill position (Fig. 7) or retro (Fig. 8).

1The angle (27) given to the bucket is specially designed to allow
continuous compaction, whatever the direction of travel
