Abstract
The powder sampling device comprises, next to a vertical channel (1) a drawer that is also vertical which may be lowered so that a groove (5) passes into a sampling mouth (12). A flap (15) may be extended to direct the powder towards the groove (5) temporarily and fill it, without the drawer (4) or the flap (15) disrupting the flow in normal circumstances nor causing any residue of powder likely to alter the measurements. In particular, the flap (15), the groove (5) and the corbelled section (2) have faces (6, 8) that are heavily angled on which the powder can only slide.
Claims3
Powder sampling device comprising:
- an appended part, generally empty of powders, of a powder flow channel (1);
- a drawer (4) traversing a wall of the appended part, and sliding between a first position where a groove (5) in it extends into the appended part and a second position where the groove extends beyond the appended part, the groove being limited by faces (7, 8) where the powder slides or falls;
- and a flap (15) in the flow channel, moving between a withdrawn position where it has no essential effect on the flow of the powders and an extended position where it directs the flow of the powders into the appended part, characterised in that the drawer (4) has an upright orientation (more or less vertical) and that the groove is limited by a ceiling face (7) and an angled face (8) which extend a base plate of the appended part when the drawer is in the first position.
