Abstract
The grain loading apparatus 2 comprises the housing 4 which is attached to the end of the grain discharge chute. The housing 4 includes a shutoff valve 12 located proximately to a material outlet opening 9. The shutoff valve 12 exerts an adjustable closure force on the material flow through the outlet opening 9 to build up a first column of material thereabove. In addition, a grain retarding cone and cylinder 92 is arranged inside the housing 4 above the shutoff valve 12. This grain retarding cone and cylinder 92 decreases the kinetic energy of the material flow and builds up a second column of material thereabove to significantly lessen release of dust into the air upon discharge of the grain strain.
