A pour spout 44 is provided in the screen mount 42 to facilitate pouring of solids left on the screen 41.
As shown in FIGS. 1 and 2, in one embodiment, the flap 46 is movably connected to the spout 44 by a chute 47. A baffle 46 is inserted during screening to prevent the sample from spilling; after screening is complete, the screen 46 is pulled out to allow the remaining solids on the screen 41 to be poured out through the pour spout 44. The flap 46 may be connected to the spout 44 in other ways (e.g., hinged to the spout 44) by simply allowing the spout 44 to be opened or closed.
In one embodiment, the screen mounting 42 is provided with at least three hooks 43.
