Patent Application
20140290203
The present invention is directed to an auxiliary feeder assembly for a baler or chopper and more particularly to a feeder assembly for picking up stover for delivery to a conventional baler or chopper.
Conventional balers and choppers are well-known in the art. When picking up stover, which is loose and made up of shorter length particles than hay, there are problems that occur. First the tines on a standard pickup device for a baler pushes the stover ahead which is not as effective or as efficient as desired. In addition, when pushing the stover forward the standard pickup device also picks up dirt in the rolling stover as corn fields are cultivated and therefore not as flat as hay fields. In the process of contacting the ground, the tines of the standard pickup device can become damaged. Thus, a device that addresses these deficiencies is desired.
Therefore, an object of the present invention is to provide a feeder assembly that increases the capacity of a baler or chopper.
Another objective of the present invention is to provide a feeder assembly that reduces dirt ingestion.
A still further objective is to provide a feeder assembly that reduces damage to a standard pickup device.
Yet another objective of the present invention is to provide a feeder that can be easily removed to return a baler or chopper to function solely with its original feeder.
These and other objectives will be apparent to one of ordinary skill in the art based upon the following written description, drawings and claims.
A feeder assembly pivotally attached to an implement forward of a pickup reel. The feeder has a continuous belt having a plurality of teeth that is mounted about a pair of rollers driven by a motor. The feeder is pivotally attached to the implement by a plurality of links that permit the feeder to pivot due to ground irregularities. Skid shoes are attached to the feeder to support the feeder and permit the pick up of stover while reducing the pick up of dirt.
Referring to the Figures, a feeder assembly 10 is mounted to an agricultural implement 12 such as a baler, a chopper or the like forward of a pickup reel having a plurality of tines 16. The assembly 10 has a frame having a first bracket 18 and a second bracket 20 connected to a tongue 22 of the implement 12. Preferably the brackets 18 and 20 are U-shaped and extend downwardly from the tongue toward the ground. A pair of links 24 are pivotally connected at one end to bracket 18 by removable pins 26. A pair of links 28 are pivotally connected to bracket 20 by removable pins 30. The opposite ends of links 18 and 20 are similarly connected to a feeder housing 32.
The feeder housing 32 includes a pair of sidewalls 34 in spaced parallel relation, a pair of rollers 36 that are rotatably connected to and extend between the sidewalls 34 and a continuous belt 38 that is mounted about the rollers 36. While a belt is described, any type of conveying device may be used such as a chain or the like. The belt 38 has a plurality of teeth or runners 40 that extend transversely across the belt 38 between the sidewalls 34. The housing 32 has a width sufficient to receive a windrow of stover or the like. Also, the housing 32 is angled in relation to the ground such that an input end 42 is near the ground and a discharge end 44 is raised in relation to the ground and positioned near and/or above the pickup reel 14.
A guide 46 is attached to the top and input end 42 of the housing 32 for directing the stover into the input end 42 of the feeder 10. Attached to the guide 46 and extending over the belt 38 is a shield 48 and a plurality of rods 50. The shield 48 and rods 50 assist in holding the stover on the belt 38.
Connected to the bottom of the housing is a skid shoe mount 52. The skid shoe mount 52 includes a support member 54 that extends between sidewalls 34 and a plurality of skid shoes 56 that are connected to support bar 54. The skid shoe 52 provides support for the feeder as it traverses the ground and assists in preventing the teeth 40 from engaging the ground while maintaining the feeder 10 in the optimal position to engage the crop.
In operation, the feeder 10 is attached to the baler 12 without the use of tools by removable pins 26 and 30. The feeder 10 is positioned at an angle such that the input end 42 is near the ground and the discharge end 44 is raised in relation to the ground and above and/or adjacent the pickup reel 14 of the baler 12. Once activated, the belt 38 is propelled by rollers 36 that are driven by a motor (not shown) such that the teeth 40 on the upper surface of the feeder 10 move toward the pickup reel 14. As the baler 12 moves forward the teeth 40 of the feeder 10 engage a windrow of stover at the input end 42 pulling the stover onto the belt 38. The stover is transported from the input end 42 to the discharge end 44 on belt 38. As the baler 12 moves across a field, the links 24 and 28 permit the feeder 10 to pivot based upon ground irregularities. Once stover reaches the discharge end 44 the stover is transferred to and received by the pickup reel 14 where further processing occurs as desired.
Thus, a feeder assembly has been shown that improves efficiency and capacity by pulling stover onto the feeder instead of pushing stover forward. Further, through use of the skid shoes and links less dirt is picked up and ingested into the pickup reel and damage to the tines of the pickup reel is reduced. Also, the feeder assembly is easily removed to permit the baler to be used for other applications such as baling hay. Finally, the feeder assembly allows the standard pick up reel to operate above crop stubble and clear of dirt.
