The present invention relates to tillage implements. More particularly, but not exclusively, the present invention relates to the use of paddles within a rolling basket.
Rolling baskets are used on any number of different tillage implements including disks, field cultivators or finishers, rippers, or other vertical tillage tools. Using rolling baskets provides for improvement of the soil bed which can result in improved crop performance.
One of the problems with rolling baskets is that if the soil is wet they will get plugged with mud which is extremely problematic as it can be very labor intensive to remove the mud and the rolling basket's ability to function as it was intended can be severely hampered. One approach that has been used to remove the mud is described in EP1639876B1 to Kaastrup. Kasstrup describes using a scraper plate attached at the ends of the rolling basket to prevent build-up of soil adhering to the rolling basket. Despite this improvement, what is needed is an improved retrofit for tillage implements with rolling baskets.
Therefore, it is a primary object, feature, or advantage of the present invention to improve over the state of the art.
It is a further object, feature, or advantage of the present invention to provide an apparatus which may be added to a tillage implement which already has a rolling basket without needing to replace the rolling basket.
It is a still further object, feature, or advantage of the present invention to allow for the use of paddles which may extend above inner, cylindrical support rings of the frame of a rolling basket in order to improve performance.
It is yet a further object, feature, or advantage of the present invention to provide a series of paddles presenting a series of paddle edges in close proximity to the rolling basket.
It is yet a another object, feature, or advantage of the present invention to provide a series of paddles presenting a sweep path extending outwardly from the rotational center of the rolling basket and terminating in paddle edges in close proximity to the rolling basket.
It is a still further object, feature, or advantage of the present invention to provide an apparatus which is easy to install.
Another object, feature, or advantage is to provide an apparatus which is effective at preventing mud build-up.
One or more of these and/or other objects, features, or advantages of the present invention will become apparent from the specification and claims that follow. No single embodiment need provide each and every object, feature, or advantage. Different embodiments may have different objects, features, or advantages. Therefore, the present invention is not to be limited to or by any objects, features, or advantages stated herein.
According to one aspect, an apparatus for use in a rolling basket of a tillage implement, the rolling basket comprising a plurality of elongated bars or blades spaced apart around a plurality of spaced apart rings, the bars or blades attached to the spaced apart rings, the apparatus includes an elongated support structure extending through a central axis of the rolling basket and a plurality of generally vertical stationary paddles spaced apart along the elongated support structure between the horizontally spaced apart rings.
According to another aspect a method of retrofitting a rolling basket attachment is provided.
According to another aspect, an apparatus for a tillage implement includes a plurality of horizontally spaced apart rings, a plurality of soil engaging elongated bars or blades spaced apart around the plurality of spaced apart rings, the soil engaging bars or blades attached to the spaced apart rings to form a rolling basket, an elongated support structure extending along a central axis of the rolling basket, and a plurality of stationary paddles secured to the elongated support structure and inter-spaced along the elongated support structure between the horizontally spaced apart rings. The plurality of stationary paddles may include first and second end paddles and a plurality of inner paddles between the first and second end paddles. The apparatus may further include first and second opposite wing plates wherein the first wing plate is secured to the first end paddle and wherein the second wing plate is secured to the second end paddle. The first end of the elongated support structure may be secured to the first end paddle inward from the first wing plate and a second end of the elongated support structure may be secured to the second end paddle inward from the second wing plate. The apparatus may further include a first box assembly including a top, a first side, a second side and the first wing plate and a second box assembly including a top, a first side, a second side and the second wing plate. The apparatus may further include a first bracket and a second bracket on opposite ends of the rolling basket. The first bracket may be secured to a first end of the elongated support structure through the first box assembly and the second bracket may be secured to a second end of the elongated support structure through the second box assembly. The stationary paddles may be generally vertical.
According to another aspect, an apparatus is provided for retrofitting a tillage implement having a plurality of spaced apart horizontal rings, a plurality of elongated bars or blades spaced apart around the plurality of spaced apart horizontal rings, the bars or blades attached to the spaced apart rings to form a rolling basket. The apparatus may include an elongated support structure extending along a middle portion of a central axis of the rolling basket, and plurality of stationary paddles secured to the elongated support structure and inter-spaced along the elongated support structure between the horizontally spaced apart rings.
Illustrated embodiments of the disclosure are described in detail below with reference to the attached drawing figures, which are incorporated by reference herein.
The paddle assembly 12 includes an elongated paddle support member 21 mounted at the center of rotation of the rolling basket. Brackets 14 are located at opposing ends of the rolling basket 11. In operation, the rolling basket 11 rotates around the paddle assembly 12. In addition, note that the use of paddles 16, 20 is advantageous over the use of a continuous blade or edge across the length of the rolling basket, because the top edge of each paddle 16, 20 can extend to the outer circumference of the cylindrical support rings 13 in close or near-touching proximity to the elongated bars 8 of the rolling basket 11 thereby further preventing mud from building up on the elongated bars 8 and within the rolling basket 11. In addition, the paddle assembly 12 may be retrofitted to an existing rolling basket as each paddle 16, 20 may be separately secured to the elongated paddle support member 21 without removing the inner rings 13 or bars 8 of the roller basket. The end paddles 16 may then be connected to the end fittings.
The present invention provides numerous advantages. First, the paddle assembly 12 may be retrofitted to existing tillage implements with rolling baskets. Thus, a farmer need not replace the rolling basket they already have thereby reducing costs. Second, the use of paddles as opposed to elongated blades allows for the paddles to be positioned higher than would otherwise be possible thus improving the ability to prevent mud from building up within the rolling basket. Third, the manner in which the paddle assembly 12 connects to the rolling basket through the fittings better adapts the paddle assembly 12 to fitting a wide range of different rolling baskets from different manufacturers.
