Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to agricultural implements, and, more particularly, to agricultural tillage implements having rolling basket attachments.

2. Description of the Related Art

Farmers utilize a wide variety of tillage implements to prepare soil for planting. Tillage equipment prepares the soil by way of mechanical agitation of various types, such as digging, stirring, and overturning. Some examples include plowing (overturning with moldboards or chiseling with chisel shanks), rototilling, rolling with cultipackers or other rollers, harrowing, and cultivating with cultivator shanks. Tillage is often classified into two types, primary and secondary. There is no strict definition of the two tillage types; however, a loose distinction between the two types of tillage is that primary tillage is deeper and more thorough while secondary is shallower. Primary tillage, such as plowing, tends to produce a rough surface finish and significantly subsoil effects, whereas secondary tillage tends to produce a smoother surface finish, such as that required to make a good seedbed for many crops. Harrowing and rototilling often combine primary and secondary tillage into one operation.

Some tillage implements include two or more sections coupled together to perform multiple functions as the implements are pulled through fields by tractors. A field cultivator is capable simultaneously of tilling soil and leveling the tilled soil in preparation for planting. A field cultivator has a frame that carries a number of cultivator shanks with shovels at their lower ends for tilling the soil. The field cultivator converts compacted soil into a level seedbed with a consistent depth for providing excellent conditions for planting a crop. Grass or residual crop material disposed on top of the soil during harvesting is also worked into the seedbed so that the residual material does not interfere with a seeding implement subsequently passing through the seedbed.

A field cultivator as described above may also include an optional rear auxiliary implement for finishing the seedbed for seeding. For example, a rear auxiliary implement may include a spike tooth harrow, spring tooth harrow, rolling basket, etc., or any combination thereof. The rolling basket has a reel with a plurality of spaced blades, positioned either axial or helical from end-to-end, for breaking clods into smaller sizes and chopping up the debris still remaining on the top of the soil.

The rolling basket arrangement can be used to roll behind the rows of tines of a harrow, to flatten the ridges left by the tines and move the residual crop material into the soil to enhance contact with the soil. The rolling basket is used to provide a firm, level field with coarse soil on top that resists crusting, with the finer soil particles at planting depth for optimum seed-to-soil contact.

One of the primary uses for rolling baskets is to break down clod sizes and firm up seed beds for subsequent planting. However, in some field conditions, a single pass with a rolling basket is insufficient for optimum clod size reduction. Making multiple passes with an independent basket implement may provide better results, but such an operation is inefficient and expensive. Implements with double baskets have been rigid, making the baskets difficult to adjust for varying ground conditions. Rigid designs with double basket have not maintained desirable ground contact over uneven surfaces and rough conditions. Further, rigid baskets encountering a large rock or other obstacle can be damaged.

What is needed in the art is a multiple rolling basket attachment for tillage equipment wherein the baskets can move to follow uneven terrain while maintaining better ground contact for clod size reduction.

SUMMARY OF THE INVENTION

The present invention provides a tillage implement with a rolling basket assembly having fore and aft baskets connected one to another by hanger assemblies that enable the baskets to follow the field contour more closely, and to walk up and over large obstacles encountered, such as large clods and stones.

The double rolling basket attachment, in one form, is directed to an agricultural tillage implement, having a frame member; a secondary frame member coupled with the frame member, and a side hanger assembly coupled to the secondary frame. The side hanger assembly includes a horizontal beam having first and second ends and a pivotal connection between the first and second ends. A first rolling basket is connected to the first end of the horizontal beam, and a second rolling basket connected to the second end of the horizontal beam.

The double rolling basket attachment, in another form, is directed to an attachment for an agricultural tillage implement having a frame. The double rolling basket attachment is provided with a forward basket, a rearward basket directly behind the forward basket and a horizontal beam having a forward end forming a rotational coupling with the forward basket and a rearward end forming a rotational coupling with the rearward basket. A leg forms a fixed connection to the secondary frame. A pivotal connection is provided between the leg and the horizontal beam.

The double rolling basket attachment, in yet another form, is directed to an agricultural tillage implement having a frame member. A secondary frame member is movably coupled with the frame member. A double rolling basket assembly is coupled with the secondary frame member. The double rolling basket assembly includes a first rolling basket, a second rolling basket behind the first rolling basket and first and second hanger assemblies at opposite ends of the first and second rolling basket. Each of the hanger assemblies has a leg connected to the secondary frame member and a horizontal beam pivotally connected to the leg. Each horizontal beam has rotatable connections to the first basket and the second basket.

An advantage of the double rolling basket attachment disclosed herein is that rolling baskets are provided in a fore and aft arrangement that promotes more effective clod size reduction and surface preparation than is provided by a single rolling basket.

Another advantage of the double rolling basket attachment disclosed herein is that baskets arranged one in front of the other can follow the field terrain more closely, to engage clods more effectively and to encounter large clods, lumps, stones and other rough surface conditions to achieve a better prepared seedbed.

Still another advantage of the double rolling basket attachment disclosed herein is that the baskets will climb up and over clods, stones or other obstacles encountered.

Yet another advantage is that the double rolling basket attachment is suitable for use with existing implements as an added attachment thereto.

FIG. 2 is a side elevational view of the agricultural tillage implement and double rolling basket attachment shown in FIG. 1; and

FIG. 3 is a top view of the agricultural tillage implement and double rolling basket attachment shown in FIGS. 1 and 2.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings more specifically and to FIGS. 1 and 3 in particular, there is shown an embodiment of a tillage implement 10. Tillage implement 10 includes a double rolling basket attachment 12 connected to a frame member 14 of implement 10. Frame member 14 is part of tillage implement 10 that is towed by a traction unit, such as by an agricultural tractor (not shown). Double rolling basket attachment 12 is connected to frame member 14 by a plurality of positioning arm assemblies 16, the positioning arm assemblies 16 extending from frame member 14 to a secondary frame member 18 that is part of double rolling basket attachment 12

Double rolling basket attachment 12 includes one or more double rolling basket assembly 20 which collectively may be thought of as an auxiliary implement for finishing the soil. The auxiliary implement also may include a spring tooth drag (not shown) with the double rolling basket assemblies 12, which act to finish the soil. In the exemplary embodiment shown, two double rolling basket assemblies 20 are shown positioned in side-by-side relationship across the width of tillage implement 10. It should be understood that for wider implements, three or more double rolling basket assemblies 20 may be used. For a small, narrow implement, one double rolling basket assembly 20 can be used.

In the illustrated embodiment, implement 10 is a disc ripper 10, having a plurality of concave, rotating discs 22 held in a disc row 24. Only a single disc row 24 is shown in the drawings for simplicity and clarity in illustration; however, it should be understood that in common applications and uses a plurality of disc rows 24 may be provided side-by-side in line with one another or angularly to one another. Implement 10 also can include additional disc rows 24 in front of the single disc row 24 that is illustrated, either in line with one another or angularly disposed with respect to one another, often at the opposite angle to the first described disc row or rows 24. Disc rippers of the type described are well known to those skilled in the art and will not be described further herein. However, it should be understood also that a double rolling basket attachment 12 as described herein can be used together with implements other than a disc ripper, such as, for example and not limitation, a chisel plow or cultivator.

With reference now more particularly to FIG. 2, each positioning arm assembly 16 includes a bracket 26 connected in fixed position to frame member 14 of implement 10. A positioning arm 28 is pivotally connected to bracket 26 at lower confronting regions thereof forming a pivotal connection 30. In the exemplary embodiment shown, positioning arm 28 is curved downwardly. A distal end connection 32 connects the distal end of positioning arm 28 to secondary frame member 18. A force applicator 34, such as a hydraulic actuator, spring or the like is connected between an upper pivotal connection 36 formed with positioning arm 28 and a pivotal connection 38 to bracket 26. Accordingly, actuation of force applicator 34 causes positioning arm 28 to rotate about lower pivotal connection 30, thereby causing the distal end of positioning arm 28 at the distal end connection 32 to move upwardly or downwardly, and thereby moving secondary frame member 18 upwardly or downwardly as well.

Each double rolling basket assembly 20 includes a forward basket 40 and a rearward basket 42 disposed in a fore and aft relationship, substantially aligned with one another. End hanger assemblies 44 are provided at each end of each basket pair including a forward basket 40 and a rearward basket 42. Hanger assemblies 44 connect baskets 40, 42 to secondary frame member 18 and thereby to positioning arm assembly 16 for movement by force applicator 34.

Each hanger assembly 44 includes a substantially vertical leg 46, the upper end of which is connected in fixed position to secondary frame member 18. A horizontal beam 48 extends between bearings 50, 52 of baskets 40, 42 respectively. Accordingly, forward basket 40 is rotatably connected to a first or forward end of horizontal beam 48, and rearward basket 42 is rotatably connected to a second or rearward end of horizontal beam 48. A pivotal connection 54 is formed between the distal end of vertical leg 46 and horizontal beam 48, substantially at a center location of horizontal beam 48, between the forward and rearward ends thereof. Accordingly, beam 48 can tilt relative to vertical leg 46 independently of any vertical movement caused by actuation of force applicator 34, thereby causing forward basket 40 to elevate while rearward basket 42 lowers or forward basket 40 to lower as rearward basket 42 elevates.

First and second rotation restrictions or stops 56, 58 are provided in horizontal beam 48, on opposite sides of vertical leg 46. First and second rotation stops 56, 58 are pedestals, posts or protrusions that encounter vertical leg 46 at maximum rotation of horizontal beam 48. As a result, horizontal beam 48 cannot rotate beyond either rotation stop 56 or rotation stops 58. First and second rotation stops 56, 58 limit the degree of pivotal rotation of horizontal beam 48 about pivotal connection 54 so that baskets 42, 44 cannot become inverted. Other types of rotation stops also can be used to limit rotation of horizontal beam 48 in either direction.

Forward basket 40 and rearward basket 42 are similarly constructed, each including a plurality of bars 60 extending between end plates 62 at each end of bars 60. Intermediate positioning or spacer rings 64 are provided to support bars 60 between end plates 62. Bars 60 may have various shapes, and can be arranged in a straight, longitudinal fashion or in a spiral arrangement.

If placed in contact with the ground, baskets 40, 42 roll as tillage implement 10 is advanced across a field. As bars 60 encounter clods of dirt or other irregularities on the ground, bars 60 act to break up the clods and irregularities. If forward basket 40 encounters a rock or clod that does not yield readily, forward basket 40 can climb up and over the obstruction, with rearward basket 42 tilting downwardly and forward basket 40 tilting upwardly as horizontal beam 48 rotates about pivotal connection 54. As rearward basket 42 encounters the same or another obstruction, rearward basket 42 can also climb up and over the obstruction if the obstruction does not yield. Forward basket 40 will rotate downwardly as rearward basket 42 elevates when horizontal beam 48 pivots about pivotal connection 54. In the case of an obstruction that is a clod or clump of soil and/or plant residue, which may have been partially broken by forward basket 40, the action of rearward basket 42 will further destruct the clod or clump.

The present invention improves overall ground contact in addition to adjusting for obstacles encountered on the surface. As upward or downward incline are encountered, the assembly of forward basket 40 rearward basket 42 and horizontal beam 48 can follow the contour change more closely, with the horizontal beam rotating about pivotal connection 54.

While this invention has been described with respect to at least one embodiment, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
