Description
Background of the Invention
Skid devices have been previously designed to be dragged behind a hay baler for the purpose of stacking hay bales into small stacks which are deposited in the field for further curing of the hay. This system of hay preparation enables baling of hay with as much as 40% moisture. The bales will go through a period of sweating for from two to five weeks but eventually dry out and remain dry.
This system enables any sweating or curing of the bales to occur in the field rather than in the barn thus avoiding discomfort to the worker and the hazards of possible spontaneous combustion. This system also enables baling of the hay without a final turning of the windrow and produces excellent quality baled hay. The method of this invention permits baling of hay of high moisture content which is dry by the wind even during periods of little sunlight, for example during October or November when a final crop of hay can often be harvested but not dried using conventional techniques.
It is an object of the present invention to provide an improved hay stacking sled which will provide six bale shocks of hay having improved stability even on steep hills. It is a further object of the invention to provide such device to provide such stacks which will stand in a rainproof fashion for drying of the hay. Further objects are to provide such a device which provides maximum safety and ease of operation. Another important objective is to provide a method of curing hay utilizing such device or similar devices for stacking bales in stable, weather-proof stacks wherein they will cure properly even under unfavorable weather conditions. It has been discovered that when hay is dried in stacks provided by the present invention, the hay dries without heating or sweating and that the protein in the hay then remains in a more readily available manner for bovine animal to digest. Moreover, it has been discovered that hay dried in accordance with the present invention contains a higher percentage of protein than hay prepared by previously used techniques apparently because it is baled in a more moist condition and thus loses less of the proteinaceous, leaves and tops than when baled in a drier more brittle condition.
Further advantages and objects of the invention will be apparent from the accompanying description and drawings, in which:
FIG. 1 is a perspective view of the rear of a skid device of the present invention;
FIG. 2 is an end view of a stack of bales formed by the device.
FIG. 3 is a side view of a device of the present invention together with a stack of bales deposited therefrom.
Description of the Preferred Embodiment
Referring now to FIG. 1, numeral 10 indicates generally a skid in accordance with the invention. At the central front portion of the skid is a standard hitch means 11 (See FIG. 3) for attaching the skid to the rear of a hay baler. Numeral 12 indicates a platform area across the front portion of the skid upon which the operator may stand. 14 and 16 are skid runners suitable for dragging the skid along the ground. Affixed to the front of platform 12 by supporting posts at each end is a hand rail 18 by supporting posts on each end upon which the bale stacking worker may steady himself. The rail is offset to one side as shown so that the opposite side remains open to bales being pushed out of the bale shute of the baler.
As shown platform 12 is raised several inches above skids 14 and 16 by supporting members 18 and 20 and are welded into one solid unit. A bale-supporting assembly 22 is positioned adjacent to the rear of platform 12 and is made up of a crossmember 24 which is preferably of about equal length to the width of platform 12 together with a plurality of bale-supporting arms 26, 28, 30 and 32. In addition there is a supporting arm 34 which is positioned outwardly and above one of the outermost bale-supporting arms, in this case number 32. Arms 26 through 34 inclusive provide a device upon which the bale stacker can place the bales one at a time to form a stack or shock.
Arms 32 and 34 are positioned so that angle A between a line drawn through the inner edge of said arms and the ground is at least 55.degree.. If said angle exceeds 55.degree., the bales may be piled to form a stable shock 40 as shown in FIG. 2. As long as angle A exceeds 55.degree. each bale within the shock will have its center of gravity to the left of center as shown in FIG. 2, i.e., the center of gravity will be positioned toward the tall side of the stack. As seen in FIG. 2, the stack is prevented from falling toward the tall side by the fact that the weight of the uppermost bales tends to push the stack in the opposite direction, i.e. toward the short side of the stack.
The bale-supporting assembly is pivotably attached to runners 14 and 16 by means of pivotable supporting elements 42, 44, 46 and 48. The latter supporting elements are attached in hinge fashion to runners 14 and 16 and to the outside of bale-supporting assembly 22. Pivotable lever arm 50 is provided to enable the bale stacker to lower the bale-supporting assembly after a six bale stack has been formed as shown in FIG. 3. Lever 50 is pivotably attached to runners 14 and 16 and also by means of connecting rod 52 to one side of the bale-supporting assembly 22.
One end of lever 50 is rigidly attached to crossmember or torsion bar 55. Member 55 provides a pivot for operation of lever 50. Rigidly affixed to the other end of pivot rod 55 is an up-right arm 56 to which is hingedly attached a second connecting rod 54 the opposite end of which is pivotably attached to assembly 22. This arrangement transmits the lowering and raising forces evenly to both sides of the bale-supporting assembly and permits the smooth lowering and raising of the assembly without twisting.
In operation the bale stacker who stands on platform 12 will stack six bales in the manner shown in FIG. 2, conventionally, the bales have a cross-section of approximately 14".times.18". As indicated they are stacked so that the long edge is more or less upright. The first bale is laid against arms 30, 32 and 34 so that the long cross-sectional service of the bale will form an angle of at least 55.degree. with the ground and preferably between 55.degree. and 80.degree.. The results in a stack of bales wherein the bottom of each bale forms an angle with the ground of 10.degree. to 35.degree..
After the stack of six bales has been formed, the operator will push lever 50 to the position shown in FIG. 3 as the skid is dragged along. This causes the bale-supporting assembly to drop down to a height where the bales will contact the ground and the skid will be pulled out from under the shock which is left behind in the field to finish curing of the hay.
As indicated, angle A should be at least 55.degree. because at lesser angles the stacked bales will tend to collapse to the right as viewed in FIG. 2. Optimum stacks are formed when the angle is between 55.degree. and 80.degree. in terms of stability of the stack even on steep hillsides. At angles greater then 80.degree. there is a tendency for the stack to tip over to the left as viewed in FIG. 2.
Thus, it will be seen that by the present invention there is provided an efficiency economical device for stacking of hay ejected from a hay-baler which is economical to construct and operate. This device is the vehicle by means of which the method of stacking bales of the invention is performed.
The method of the present invention involves orienting an odd numbered plurality of bales in a row with an edge of each bale positioned at its lower-most position, each bale having a flat surface in contact with each of the adjoining bales, the axis of each bale being parallel to the ground and the bottom of each bale forming an angle with the ground of 10.degree. to 35.degree., and the shortest sides of each bale being in the upper and lowermost position; positioning a second row of bales parallel and on top of said first row, the shortest sides of the bales in the second row being in direct face to face contact with the top sides of the bales in the first row, said second row having one less bale therein than said first row; stacking additional rows of bales in the same relationship over said second row with the uppermost row consisting of only one bale, and lowering the resulting pyramidal stack onto the ground to allow the same to dry by exposure to the elements.
Example
High moisture content third crop hay was baled in Northern Wisconsin in mid-November in stacks as indicated. After 3 weeks curing in generally damp, cloudy weather conditions the hay was examined and found to be of excellent quality. The hay was found not to heat or sweat during curing. Protein content was analyzed to be 24%. 12% is considered to be a normal, good protein content for baled hay. It was of a type readily available to animals during digestion.
