Abstract

An apparatus for creating a stockpile of bulk material, comprising a conveyor having a feed end and a distribution end; a stabilizer at the feed end of the conveyor; and a support at the distribution end of the conveyor; wherein the support includes a primary hydraulic cylinder having a base portion connected to the support and an end portion which extends and retracts longitudinally to alter the angle between the conveyor and the ground; and a secondary hydraulic cylinder having one end connected to the support and the other end connected to the primary hydraulic cylinder, where the secondary hydraulic cylinder extends and retracts in a lateral direction, thus pivoting the primary hydraulic cylinder against the support. This design is simpler and less expensive than a conveyor with an undercarriage and makes for a smaller staging area as room for the undercarriage is unnecessary.

Claims18

Dependent claims

An apparatus for creating a stockpile of bulk material, the apparatus comprising:

a conveyor portion having a feed end and a distribution end;
a stabilizer at the feed end of the conveyor for limiting the movement of the feed end of the conveyor, and creating an angle between the conveyor portion and the ground;
and
a support at the distribution end of the conveyor portion;
the support includes an end portion;
and
wherein the support is configured to raise the distribution end by:
raising the end portion away from the stockpile and closer to the conveyor apparatus, and during the raising of the end portion, the end portion is pulled through the stockpile, with the support acting against the stockpile;
and
extending, after raising the end portion closer to the conveyor apparatus, the end portion away from the conveyor apparatus so that the end portion rests on the stockpile, and during subsequent extension, the end portion acts against the stockpile, raising the support, to move the distribution end higher atop the stockpile;
and
whereby movement of the end portion increases the angle (α) between the conveyor portion and the ground, giving the conveyor apparatus more height to deposit further said bulk material above the stockpile.
