METHOD AND MACHINE FOR FORMING A COMPACT STACK OF CROP MATERIAL

摘要

A compact stack forming machine, having a mobile chassis adapted to move across a field, includes an upright delivery tube mounted on the chassis with a pickup mounted at its lower end adjacent the field for picking up crop material from the field and propelling the crop material through the tube and into a stack forming chamber, being mounted on the chassis rearwardly of the tube and pickup, through a first open end toward an opposite second end of the chamber with sufficient velocity to substantially reach the second end thereof, a carriage frame extending across the chamber and moveable between the chamber ends with a baffle member being moveably mounted thereon for at least partially deflecting the propelling crop material from time to time during movement of the carriage frame to distribute the crop material within the chamber between the ends thereof and thereby progressively form a stack of the crop material in the chamber, and a packing roll extending across the chamber below the baffle member and moveable between the chamber ends to compact the distributed crop material as the stack is progressively formed in the chamber.
