Elastically deformable truck bed hopper for mining dump truck

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.

Description

technical field [0001] The present invention relates to bedhoppers for high, medium or low tonnage mining dump trucks, and more particularly to bedhoppers having curved surfaces at their bottom, leading area, and slot cover so that there is no need for bedhoppers in the leading area and Beams are placed in the seam cover, and the number of beams at the bottom of the hopper frame can be substantially reduced. Background technique [0002] Mining hoppers in use today, whose construction materials are arranged in a flat surface at the blinder, side and front walls, and bottom, are aligned by longitudinal outer beams, transverse beams, or a combination of longitudinal and transverse beams For reinforcement. These beams provide rigidity to the plates forming the hopper. In the prior art, the necessary moment of inertia provided by the beam is used to resist the stresses generated by the load. This type of construction reduces the ability of the hopper to deform elastically, is...

Problems solved by technology

[0008] In each of the described hoppers, the overall weight is increased due to the use of multiple beam structures to reinforce each surface
