Abstract
A device for depositing a layer of granular material on a deposition surface. The device includes a discharge hopper, a scraper, and a transporter to move the discharge hopper and the scraper relative to the deposition surface. The hopper includes a plurality of discharge holes, aligned in a transverse direction, a top portion and a conical bottom discharge portion. The bottom discharge portion includes two transverse walls that are inclined towards the discharge holes. Each compartment, of a transverse compartmentalization of the discharge portion, includes two walls perpendicular to the transverse walls of the conical bottom discharge portion and inclined towards the discharge holes. Each compartment facing a discharge hole forms a pyramid-shaped conduit in the bottom discharge portion. The consecutive walls of the two compartments being joined at a corner where they meet in the bottom discharge portion.
