Abstract

A truck bed hopper of a mining dump truck that is capable of elastic deformation when it is subject to the loading or unloading of material, built preferably of structural or of wear and tear steel, where the general structure of the bed hopper is curved. By this construction, the great moments of inertia which are achieved with curved surfaces eliminate or reduce to a great extent the use of beams as main resistive elements. The present bed hopper has a protective blinder which is preferably cylindrical in shape and a frontal wall and floor which are preferably elliptical in shape. The bottom of the bed hopper externally has a plurality of transversal beams, preferably 4 to 6 in number, even more preferably 5 in number which have a main function of keeping the bottom surface curved and transferring the strengths of the envelopment to the truck'"'"'s body. Further, the bottom externally also has a plurality of support elements, preferably two in number, that are located at the front part, i.e., ahead of the rotation axis of the hopper. The support elements only permit the support of the bed hopper on the truck'"'"'s body and may be eliminated if the truck'"'"'s body adapts itself to directly take in the transversal beams.

Claims

1. An elastically deformable mining truck hopper comprising:

a frontal wall, protective blinder, and bottom having curved surfaces, formed by construction materials capable of generating the same;

a plurality of curved transversal beams at the bottom; and

at least one curved transversal beam and two lateral beams in the blinder.

2. A hopper according to claim 1, wherein the curved surface of the protective blinder is preferably of the cylindrical type and the curved surfaces of the protective blinder and bottom are preferably of the elliptical type.

3. A hopper according to claim 1, wherein the curved transversal beams of the bottom of the hopper are preferably from 4 to 6 in number.

4. A hopper according to claim 3, wherein the curved transversal beams of the bottom of the hopper are 5 in number.

5. A hopper according to claim 1, further comprising supporting elements in the longitudinal direction, that support the hopper to the chassis of the mining truck.

6. A hopper according to claim 5, wherein the supporting elements in the longitudinal direction are 2.

7. A hopper according to claim 1, wherein the transversal beams with the supporting elements in the longitudinal direction meet at a coupling of the sliding type.

8. A hopper according to claim 1, wherein the transversal beams are of “

T”

section or double “

T”

section.

9. A hopper according to claim 1, wherein the construction material is structural steel.

10. A hopper according to claim 1, wherein the construction material is wear and tear steel.
