Abstract: A tractor drawn and powered machine is disclosed for forming large round bales of fibrous agricultural crops in a chamber of fixed size. The baling chamber consists of a lower and an upper section. The lower section includes a wheel mounted main frame, along with a pickup reel and a bottom conveyor comprising side by side belts entrained on four transversely extending rollers. The upper section is supported on a subframe which is hinge mounted along its front edge to the main frame allowing thereby the rear portion of the upper section to open as a rearward facing tailgate for discharge of a completed bale. Situated within the subframe of the upper section are all of the conveying elements which make up the rear, top and front of the generally cylindrical periphery of the baling zone. Each conveyor element in the upper section comprises a plurality of side by side belts entrained on spaced apart transversely mounted upstream and downstream rollers.

Abstract: An ejection mechanism is described which automatically assists in the discharge of completed bales from the bale-forming chamber. As implemented the ejection mechanism forms a part of a baler which produces generally cylindrical bales in a chamber of fixed size having closed sidewalls adjacent the ends of the bale. The baling chamber is divided into two parts with one portion being hinge mounted along its front edge to allow its second or rear edge to swing open upwardly to provide a gate through which completed bales can be discharged. The second portion of the baling chamber contains a bottom conveyor for imparting rotational motion to the bale during the crop gathering and bale forming process. When the bale in the chamber is completed and ready for discharge, the gate swings open and the bottom conveyor continues moving in a front to rear direction.
