DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

[0043] FIGS. 1 and 2 depict perspective diagrams of the loading of a bulk material into the bucket. These two figures show the step of loading the bulk material from two different viewpoints.

[0044] The loading can be various types of material: [0045] all grades of gravel 0/20, 0/31.5, etc. [0046] sand (stabilized), [0047] chippings, [0048] cement concrete (depending on the water content), [0049] asphalt concrete (coated), [0050] etc.

[0051] The bucket is used to load the bulk material from a heap. In another embodiment, the bucket is used to collect a bulk material under the dump gate of a truck.

[0052] FIGS. 3 and 4 depict a diagram of the tipping of a bulk material out of the bucket. These two figures show a step in the tipping-out of the bulk material, from two different viewpoints.

[0053] In this case, the opening gate allows the bulk material to be released and to pour out.

[0054] FIGS. 5 and 6 depict a diagram of the spreading of a bulk material using the bucket that forms the subject of the present invention. These two figures show a step of spreading the bulk material from two different viewpoints.

[0055] More particularly, FIG. 6 shows the roller adjusted in such a way that the bottom of the bucket is held a certain distance off the ground. In this way, the roller dictates the thickness of the bulk material. Adjusting this distance regulates the thickness of the layer of material distributed after the spreading phase.

[0056] The material leaves the bucket via the opening gate which releases the bulk material under the effect of gravity.

[0057] FIG. 7 depicts the bucket on which the cranks 26 are mounted. Shown here are the adjusting system 25, the roller 27 and the support panel 22.

[0058] FIG. 8 depicts an exploded view of a bucket. Shown here are two lateral panels 20 extending on each side of a loading panel 21, the support panel 22 to which the adjusting system 25 with the roller 27 and the cranks 26 is fixed. Also shown is the opening panel 23 comprising a gate 24.

[0059] The loading panel 21 has four edges, two edges connecting the lateral panels 20, a loading edge 211 delimiting part of the main opening of the bucket, an unloading edge 212 delimiting part of a secondary opening. The unloading edge is on the other side of the panel from the loading edge 211. The secondary opening is controlled by the opening of the gate 24 on the opening panel 23.

[0060] FIGS. 9 and 10 depict two alternative forms of bucket with two different types of fixing attachment 28 for a type of vehicle. The two attachments both have the same functionalities but differ only in terms of the system for fixing to the vehicle. The attachment is produced in such a way that it fits the chosen vehicle while at the same time maintaining the rotation and translation so that the attachment is floating relative to the ground.

[0061] FIG. 11 depicts a side view of the bucket. A roller connected to the adjusting system 25 can be seen. The roller 27 is made of steel and situated to the rear of the bucket. When the bucket is in the spreading position, the roller 27 rests on the ground.

[0062] The adjusting system 25 comprises two hand cranks (one on each side of the bucket), this is adjustable height-wise and thus makes it possible to choose the thickness E to be spread. The ground is depicted in dotted line and the difference between the bottom of the bucket and the ground is indicated by the reference E.

[0063] In one embodiment, the thickness differs from one side to the other.

[0064] The roller 27 has the advantage of having a bearing surface over the entire length of the bucket, thus avoiding under-thicknesses.

[0065] FIG. 12 depicts a rear view of the bucket. It shows a fixing attachment 28 on which the position of the fixing attachment 28 is over-inclined relative to the bucket. Specifically, the fixing attachment 28 has transverse mobility (arrow A) relative to the support panel 22.

[0066] The fixing attachment 28 also has the ability to move about an axis of rotation 29 relative to the ground (arrow B). The axis of rotation is perpendicular to the support panel 22.

[0067] FIG. 13 depicts a perspective view of the bucket mounted on a vehicle according to one embodiment.

[0068] In an alternative form of embodiment, the mobile roller 27 is replaced by a caterpillar track system.

[0069] In one embodiment, the width of the bucket is 2 m. It is comprised between 1 and 3.5 m.

[0070] In another embodiment, the bucket comprises several opening gates making it possible to vary the spreading width.

[0071] In another embodiment, the opening gate comprises a guideway system to slide the gate from left to right, thus varying the spreading width.

[0072] The diameter of the roller is 20 cm. It is comprised between 10 and 50 cm.

[0073] In another alternative form which has not been depicted, the bucket comprises a plate positioned above the bucket leaving a width of opening that can be varied between 0.5 and 5 cm so that the chippings can be spread by inclining the bucket.
