Abstract

A crop harvesting system for continuous round baling is described that comprises a first and second bale chamber and a conveyor system in operable communication with the first and second bale chambers. The crop harvesting system can comprise a first bale chamber comprising a variable shape, defined by a first serpentine system comprising one or a plurality of endless belts in operable contact with one or a plurality of movable rollers to facilitate movement of the bale out of the first and into the second bale chamber. The second bale chamber comprises a fixed shape defined by a plurality of stationary rolls operably attached to a second set belt or belts. The crop harvesting system can be integrated into an agricultural harvester such as a baler or combine.

First claim

The invention claimed is:

1. A crop harvesting system, comprising:
a first bale chamber and a second bale chamber operably coupled by a conveyor system;
wherein the first bale chamber is positioned at a front of the baler and the second bale chamber is positioned at a rear of the baler, wherein each of the first and second bale chambers comprise a first sidewall and a second sidewall, an entry point at the front of the first and second bale chambers, an outlet at a rear of the first and second bale chambers, and at least one floor roller positioned at a bottom of each of the bale chambers transverse to the first and second sidewalls;
wherein the conveyor system is positioned between the first and second bale chambers;
wherein the first bale chamber comprises a variable shape, defined by a first serpentine system comprising at least one belt in operable contact with at least one movable roller to facilitate movement of a bale in the first bale chamber, and out of the first bale chamber and into the second bale chamber; and
wherein the second bale chamber comprises a plurality of stationary rollers,
wherein the second chamber further comprises a gate roller in contact with the at least one belt, wherein in a first operable condition, the gate roller is positioned in a lower position closing the entry point at the front of the second bale chamber, and wherein in a second operable condition, the gate roller is positioned in an upper position exposing the entry point at the front of the second bale chamber; and
wherein the first serpentine system comprises a bale carrier positioned forward of the gate roller, wherein in the first operable condition, the bale carrier is positioned in a lower position closing the outlet at the rear of the first bale chamber, and wherein in the second operable condition, the bale carrier is positioned in an upper position exposing the outlet at the rear of the first bale chamber.

2. The crop harvesting system of claim 1 , wherein the plurality of stationary rollers are coupled to a tailgate and configured to pivot with the tailgate in an open position of the tailgate.

3. The crop harvesting system of claim 1 , wherein the plurality of stationary roller comprises a first group of stationary rollers coupled to a tailgate and configured to pivot with the tailgate in an open position of the tailgate, and a second group of stationary rollers coupled to a main frame and configured to remain stationary during pivoting of the tailgate.

4. The crop harvesting system of claim 1 , further comprising a take-up assembly comprising a plurality of stationary rollers and a plurality of movable rollers, the at least one endless belt of the first serpentine system extending between the plurality of stationary and movable rollers of the take-up assembly at non-parallel and non-perpendicular angles relative to horizontal.

5. The crop harvesting system of claim 1 , wherein the gate roller is configured to slide along a track formed in at least one of the sidewalls between the upper and lower positions.

6. The crop harvesting system of claim 5 , wherein the plurality of stationary rollers of the second bale chamber define a substantially continuous, semi-circular configuration at the rear of the second bale chamber.

7. The crop harvesting system of claim 5 , wherein the second bale chamber further comprises a chain or belt extending over the plurality of stationary rollers to define a substantially continuous, semi-circular configuration at the rear of the second bale chamber.

8. The crop harvesting system of claim 1 , wherein as the bale is formed within the first bale chamber, the bale carrier remains in the lower position and the at least one belt extends over the bale, preventing movement to the second chamber and the gate roller remains in the lower position tensioning the at least one belt.

9. The crop harvesting system of claim 8 , wherein the gate roller is configured to slide along a track between the upper and lower positions.

10. A continuous round baler, comprising:
a main frame;
a pickup assembly disposed near a forward end of the main frame; and
a first bale chamber positioned rearward of the pickup assembly;
a second bale chamber operably coupled by a conveyor system to the first bale chamber;
an entry point at the front of the first and second bale chambers, an outlet at a rear of the first and second bale chambers, and at least one floor roller positioned at a bottom of each of the bale chambers;
wherein the conveyor system is positioned between the first and second bale chambers;
wherein the first bale chamber comprises a variable shape, defined by a serpentine system comprising at least one belt in operable contact with at least one roller to facilitate movement of the bale in the first bale chamber, and out of the first bale chamber and into the second bale chamber; and
wherein the second bale chamber comprises a fixed shape, comprising a plurality of stationary rollers and a gate roller in contact with the at least one belt, wherein in a first operable condition, the gate roller is positioned in a lower position closing the entry point at the front of the second bale chamber, and wherein in a second operable condition, the gate roller is positioned in an upper position exposing the entry point at the front of the second bale chamber; and
wherein the first serpentine system comprises a moveable portion toward the rear of the first outlet of the first bale chamber such that, in the first operable condition, the at least one belt and a plurality of rollers positioned toward the rear of the first bale chamber are positioned in a lower position sufficiently preventing movement of crop material from the first bale chamber to the second bale chamber; and, in the second operable position, the at least one belt and the plurality of rollers positioned toward the rear of the first bale chamber are positioned in an upper position to accommodate movement of a full formed bale in the first chamber to exit through the outlet of the first bale chamber.

11. The continuous round baler of claim 10 , wherein the conveyor system is positioned between the first and second bale chambers at a downward angle from a front of the baler to a rear of the baler.

12. The continuous round baler of claim 10 , wherein the conveyor system comprises at least two rollers and a conveyor belt positioned over the at least two rollers wherein rotation of the at least two rollers causes the conveyor belt to move harvested crop from the first bale chamber to the second bale chamber.

13. The continuous round baler of claim 10 , wherein the at least one belt and plurality of rollers are integrated into a bale carrier.

14. The continuous round baler of claim 10 , wherein the first serpentine system comprises at least one take-up assembly positioned in the front of the baler comprising an arm capable of radial movement around a stationary pivot point and at least two movable rolls operably attached to the arm and the at least one belt, wherein, in the first operable condition, the arm is positioned in a rearmost position thereby decreasing the length in the at least one belt and, in the second operable condition, the arm is positioned in a frontmost position thereby increasing the length in the at least one belt and moving the at least one belt and the at least two moveable rolls from a lower position in the rear of the first bale chamber to an upper position thereby accommodating the movement of crop material from the first to the second bale chamber.

15. The continuous round baler of claim 10 , further comprising a first sensor posit
