Abstract

A feeding system for an agricultural implement includes a hopper configured to receive agricultural crop material. An auger extending across the hopper is configured to meter the agricultural crop material from the hopper into a tapered passageway. A movable belt is disposed along one side of the tapered passageway and is configured to urge the agricultural crop material through the tapered passageway toward an outlet of the tapered passageway to form the agricultural crop material into a mat having a thickness substantially equal to a width of the outlet.

First claim

What is claimed is:

1. A feeding system for an agricultural implement, comprising:
a hopper configured to receive agricultural crop material;
an auger extending across the hopper, wherein the auger is configured to meter the agricultural crop material from the hopper into a tapered passageway;
a movable belt disposed along one side of the tapered passageway, wherein the movable belt is configured to urge the agricultural crop material through the tapered passageway toward an outlet of the tapered passageway to form the agricultural crop material into a mat having a thickness substantially equal to a width of the outlet;
a sensor assembly configured to output signals indicative of the thickness of the mat, a weight of the mat, a density of the mat, or any combination thereof; and
a controller configured to receive the signals from the sensor assembly indicative of the thickness, the weight, the density, or the combination thereof, and to adjust a position of the movable belt, an orientation of the movable belt, a speed of the movable belt, or any combination thereof, based on the signals to control the thickness of the mat, the weight of the mat, the density of the mat, or a combination thereof.

2. The feeding system of claim 1 , comprising a conveyor disposed vertically below the outlet, wherein the conveyor is configured to receive the mat from the outlet and to transfer the mat toward a baling chamber of the agricultural implement.

3. The feeding system of claim 1 , comprising a pneumatic conduit coupled to an inlet of the hopper and configured to deliver the agricultural crop material to the hopper via an air flow.

4. The feeding system of claim 1 , wherein the auger comprises a first helicoid structure in a first portion of the auger and a second helicoid structure in a second portion of the auger, and the first helicoid structure is oriented in a first orientation, and the second helicoid structure is oriented in a second orientation, different from the first orientation.

5. The feeding system of claim 4 , wherein the first helicoid structure and the second helicoid structure are configured to urge the agricultural crop material to a center portion of the hopper, and the tapered passageway extends vertically below the center portion of the hopper.

6. The feeding system of claim 1 , wherein the movable belt comprises lateral protrusions that extend into the tapered passageway, and the lateral protrusions are configured to engage the agricultural crop material and urge the agricultural crop material toward the outlet.

7. The feeding system of claim 1 , wherein the controller is configured to adjust a dimension of the outlet based on the signals.

8. A feeding system for an agricultural implement, comprising:
a hopper configured to receive agricultural crop material;
an auger extending across the hopper, wherein the auger is configured to meter the agricultural crop material from the hopper into a tapered passageway;
a movable belt disposed along one side of the tapered passageway, wherein the movable belt is configured to urge the agricultural crop material through the tapered passageway toward an outlet of the tapered passageway to form the agricultural crop material into a mat having a thickness substantially equal to a width of the outlet;
a sensor assembly configured to output signals indicative of the thickness of the mat, a weight of the mat, a density of the mat, or any combination thereof; and
a controller configured to receive the signals from the sensor assembly indicative of the thickness, the weight, the density, or the combination thereof, and to adjust a dimension of the outlet based on the signals.

9. The feeding system of claim 8 , comprising a conveyor disposed vertically below the outlet, wherein the conveyor is configured to receive the mat from the outlet and to transfer the mat toward a baling chamber of the agricultural implement.

10. The feeding system of claim 8 , comprising a pneumatic conduit coupled to an inlet of the hopper and configured to deliver the agricultural crop material to the hopper via an air flow.

11. The feeding system of claim 8 , wherein the auger comprises a first helicoid structure in a first portion of the auger and a second helicoid structure in a second portion of the auger, and the first helicoid structure is oriented in a first orientation, and the second helicoid structure is oriented in a second orientation, different from the first orientation.

12. The feeding system of claim 11 , wherein the first helicoid structure and the second helicoid structure are configured to urge the agricultural crop material to a center portion of the hopper, and the tapered passageway extends vertically below the center portion of the hopper.

13. The feeding system of claim 8 , wherein the movable belt comprises lateral protrusions that extend into the tapered passageway, and the lateral protrusions are configured to engage the agricultural crop material and urge the agricultural crop material toward the outlet.
