Ejection chute for agricultural baler
An agricultural baler includes a bale chamber having a discharge outlet and a bale ejection system configured to discharge bales from the bale chamber on the ground surface of the field. The bale ejection system includes a chute with a first half portion and a second half portion that receives a first bale and a second bale discharged simultaneously from the discharge outlet in the first half portion and the second half portion, respectively, and an ejection actuator that pushes the second bale from the second half portion of the chute to the first half portion of the chute.
1. An agricultural baler, comprising:
a bale chamber having a discharge outlet; and
a bale ejection system configured to discharge bales from the bale chamber on a ground surface of a field, the bale ejection system including:
a chute having a first half portion and a second half portion, the chute being configured to receive a first bale and a second bale in the first half portion and the second half portion, respectively; and
an ejection actuator configured to push the second bale from the second half portion of the chute to the first half portion of the chute such that the first bale and the second bale are discharged in a single line on the ground surface of the field,
wherein the at least one bale position sensor comprises a first bale position sensor configured to sense the presence or absence of the first bale in the first half portion of the chute and a second bale position sensor configured to sense a presence or absence of the second bale in the second half portion of the chute,
wherein the ejection actuator is configured to push the second bale from the second half portion of the chute to the first half portion of the chute when the second bale position sensor senses the presence of the second bale in the second half portion of the chute and when the first bale position sensor senses the absence of the first bale in the first half portion of the chute.
2. The agricultural baler of claim 1 , wherein the chute is angled downwardly from the discharge outlet toward the ground surface of the field to cause a downward sliding movement of the first bale through the first half portion of the chute.
3. The agricultural baler of claim 1 , wherein the chute comprises a wall formed at an end of the second half portion of the chute.
4. The agricultural baler of claim 3 , wherein the end of the second half portion of the chute is closer to the ground surface of the field than to the discharge outlet.
5. The agricultural baler of claim 3 , wherein the wall is configured to prevent a downward sliding movement of the second bale through the second half portion of the chute to the ground surface of the field.
6. The agricultural baler of claim 1 , wherein the ejection actuator is arranged in, on or adjacent to the second half portion of the chute.
7. The agricultural baler of claim 1 , wherein the ejection actuator comprises a pusher plate configured to engage with a side portion of the second bale.
8. The agricultural baler of claim 7 , wherein the ejection actuator is configured to push the second bale from the second half portion of the chute to the first half portion of the chute when the second bale position sensor senses the presence of the second bale on the pusher plate.
9. The agricultural baler of claim 1 , wherein the second bale position sensor is arranged near the pusher plate.
10. The agricultural baler of claim 9 , wherein the ejection actuator is configured to push the second bale from the second half portion of the chute to the first half portion of the chute after a predetermined period of time expires.
11. An agricultural vehicle comprising the agricultural baler of claim 1 .
12. The agricultural baler of claim 7 , wherein the pusher plate moves from a first position adjacent a side wall of the bale chamber to a second position at an intersection between the first half portion and the second half portion of the chute.
13. The agricultural baler of claim 12 , wherein the first bale moves in a longitudinal direction along the first half portion, and the pusher plate moves between the first and second positions in a transverse direction that is orthogonal to the longitudinal direction.
14. The agricultural baler of claim 13 wherein the second sensor is pointed in the longitudinal direction.
15. The agricultural baler of claim 1 , wherein the first half portion and the second half portion of the chute are angled downwardly at a same angle.
16. The agricultural baler of claim 1 , wherein the first half portion is angled downwardly with respect to the second half portion of the chute.
17. The agricultural baler of claim 1 further comprising a control system including a controller that receives inputs from the first and second sensors and controls the ejection actuator based upon those inputs.
18. The agricultural baler of claim 1 , wherein the first and second sensors are pointed in different directions.
19. The agricultural baler of claim 1 , wherein the first half portion and the second half portion terminate at a common edge.
