Description
CONSERVATION IMPLEMENT INCLUDING A DEFIBRATOR
BACKGROUND OF THE INVENTION
1) Field of the Invention:
The present invention relates generally to agricultural tillage implements and more specifically to multi-function single pass implements which include a defibrator device.
2) Related Art:
Many tillage practices require several steps after harvesting a crop to prepare the soil for planting the next crop. Typically after harvesting, the farmer must first defibe the crop residue, and then break the soil and prepare a bed of seeds suitable for planting. Several different implements are frequently used in separate operations in the field. Each operation usually requires at least one separate step on the field with a tractor and an implement. Therefore, operating costs are high and considerable time and energy are consumed in the preparation of the land. The compaction of the increased terrain occurs as a result of multiple passes on the ground. Because two or more implements are required for the preparation of the seed bed, the initial cost of the equipment is also relatively high.
Even though multi-function conservation tillage tools are currently available on the market, many fail to provide a good shredding function for the crop residue which is present in the fields where the maize, sorghum or wheat crops have been harvested. other crops of heavy scion. Some conservation implements work well in certain soil conditions and crop residue but are not particularly well adapted to other crop and field conditions, nor can they be easily modified for different conditions.
Many past attempts to provide a combination of tillage and shredding tool have found only limited success. Some include towing hooks connected by a heavy, large clamp to the front drawbar to pull implements such as a disc behind the shredder. Shredders with drag hooks and pull-type implements can be difficult to transport and control of the rear implement during tillage operations is sometimes a problem. Deep-tillage tools such as rippers usually can not be used effectively with the trailer hitch.
Combination structures having tillage and stem cutting tools, as shown in U.S. Patent No. 2,781,709, include a bell lever arrangement holding a tool bar and the ground contact wheels. The joints are often large, extend above the implement, and are suitable only for a relatively low profile cutter having a horizontally extending blade rotating about a vertical axis. Another type of tool shown in United States Patent No. 3,233,683 includes a rod cutting device with a tool support rod connected by the special arched clamps to the back of a stem cutter. The rod and clamp construction has limited versatility and is suitable only for relatively light loads and not for loads that are found by deep-tilling tools. U.S. Patent No. 3,601,202 shows a tool bar mounted behind a shredder but fails to provide any teaching to effectively mount the tool bar on the shredder frame to accommodate heavy pull loads.
BRIEF SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an improved agricultural implement for conservation and conventional tillage. It is also an object to provide such a structure which overcomes most or all of the aforementioned problems.
It is a further object of the invention to provide an improved conventional and conservation tillage implement which defibrates the harvest residue effectively prior to breaking or tillage of the soil. It is another object to provide such an implement which has good soil and waste flow characteristics and can be adapted for operation in highly variable harvest and field conditions.
It is a further object of the invention to provide an improved conservation and conventional tillage implement having a shredder and a towing tool bar for mounting a variety of tillering tools in the shredder for single-pass ultifunction operations. It is another object to provide such an implement which is easy to modify to accommodate different crop and field residue conditions.
It is still another object of the invention to provide an improved conventional and conservation tillage implement having a shredder with at least one integral tool bar for assembly of the tillage equipment, including deep tillage tools. It is still another object to provide such an implement which has a compact but strong frame structure and which does not require large lifting frames or other lifting structures extending over the shredder. It is a further object to provide a versatile tool mounting arrangement for such an implement to support a variety of trailer tillage implements, including deep tillage and disc tools, in both field and transportation work positions, and It can be adapted for either the tow bar hitch assembly or the three point hitch.
A tillage implement constructed in accordance with the above-mentioned objects includes a shredder having a transverse rotor with rotating shelling machines about an axis transverse to the forward direction. The shredder includes a curved metal cross-section structure defining a rotor compartment. The one-piece end panels are connected to each side of the cover structure and extend rearwardly from the shredder. The backs of the end panels include the openings conforming to the cross section of a tool bar which extends to the width of the implement and projects through the openings. The bar? E tools are welded to the panels which also support the belt drive structure connected to a PTO drive through transverse axes that extend outward from a central drive location to one side of the attachment structure of the implement. The tool bar, offset by a substantial distance backward from the cover structure and located at a substantial distance above a horizontal plane passing through the rotor shaft, provides convenient operator access to the various adjustable clamps and facilitates the longitudinal staggering of the tools that are transversely spaced on the toolbar. You can also add an additional toolbar to the first toolbar.
The center of the toolbar is connected to a pair of vertical center panels which are connected to the central rear part of the cover. A reinforcing member extends from the central rear part between the central panels around the upper part of the cover adjacent to the latching structure which connects the implement to a tractor. The end and center panels and the reinforced cover structure define a non-obstructive and compact frame which is strong enough to pull heavy drawbar loads and withstand heavy force loading. In an embodiment of the invention, the tool bar holds a plurality of transversely adjustable deep tillage tools such as the scrapers, and the disk structure is connected by an adjustable clamp structure to the tool bar behind the scrapers. The transversely adjustable transport and lifting wheels are also connected to the tool bar, together with the transversely adjustable limit-down members to limit the descent of the disc relative to the tool bar and the disc structure support above. from the ground when the wheels are lowered to raise the frame to the transport position. A variety of ground work tools, including those that present a heavy draft load, can be mounted on the tool bar. The locations of these tools along the toolbar can be varied using adjustable clamps to provide numerous combinations and implement arrangements. The toolbar support panels are narrow to minimize any interference with the adjustable clamps. The back of the clamp can be provided with a variable aperture or transversely spaced apertures to advantageously control the flow of the defibrated material relative to the towing tools for optimal garbage flow and controlled ground coverage.
The implement reduces the capital investment required by the farmer, reduces the preparation time. of the land and operating costs, and reduces the compactacicr. from the earth. The implement has good garbage handling characteristics and can operate under heavy residue conditions without clogging. The compact and strong frame structure including the rear tool bar accommodates numerous combinations of implements with the shredder, including deep-tilling tools featuring high draft loads and high tool bar torsional force, and the implement can be used with be conventional or conservation tillage practices.
These and other objects, features and advantages of the present invention will be apparent from the drawings and the detailed description that follows.

DETAILED DESCRIPTION OF THE PREFERRED MODALITY
Referring to Figure 1 there is shown a combination implement 10 including a shredder having a forward trailer hitch structure 14 adapted for attachment to a tractor strip bar (not shown) for a forward movement over a field where a crop residue such as corn rods are present. In a second embodiment (Figure 3) the three-point hitch structure 14 'is connected to the shredder 12 to hold the implement to the three-point hitch on a tractor.
The defibrator 12 includes a metal cover structure 20 defining a rotor compartment that opens downward and curved generally at point 22 in Figure 3 having the opposite outer ends 24 and 26. A front transverse panel 28 extends essentially to the width of the implement at the lower front edge of the compartment 22 and is connected to the pull-type latch structure 14 (Fig. 1) or to the integral latch 14 '(Fig. 3). A rear panel 29 extends the width of the implement and generally closes the rear of the compartment. Alternatively, the panel 29 may define a pair of vertically adjustable rear cover portions, or a series of transversely spaced rearwardly spaced openings 29 'to selectively direct the material relative to the towing tools. A conventional shredder drive assembly, a part of which is shown at point 30 in Figure 3, is connected to the PTO tractor and the rotating transverse axes about an axis 32 to energize the belt drives 33 in the compartments. of drive 34 and 36 located on one side of the ends 24 and 26 respectively. A rotor 40 (FIG. 3) is supported to rotate about a transverse axis 42 below the cover structure 20 in the compartment 22 and is driven from the PTO of the tractor through the assembly 30 and the belt drives 33. The blades 46 are supported from the rotor 40 to spray the plant material such as stems and stubble.
The end panels or plates 54 and 56 are fixed to the ends 24 and 26 to close the sides of the compartment 22 and providing support for the drives in the compartments 34 and 36. The plates 54 and 56 are preferably unitary planar members with integral rearward extensions 64 and 66. The horizontally placed gussets 68 and 70 are secured to the plates 54 and 56 to one side of the lower edges of the plates. The rear ends of the extensions 64 and 66 include the rectangular openings 74 and 76. A transverse tool bar 80 is supported from the end panels 54 and 56 by a substantial distance behind the roof structure 20 above the axis level of rotor 42 (figures 2 and 3) and extends generally to the width of the implement 10. Tool bar 80 is of tubular construction with a cross section conforming to the shape of openings 74 and 76. The tool bar 80 includes the left and right ends 84 and 86 held in the openings and extending outward from the plates 54 and 56. The plates 54 and 56 which are welded to the ends 84 and 86, have a narrow profile to limit the interference with several clamps, discussed in detail below, these are provided to attach devices to the tool bar 80. The additional narrow vertical plates 88 are fixed to the central part of the cover structure 20 and have the pierced rear ends 90 which receive and are welded to the central part of the tool bar 80. A central reinforcing member 92 is connected to the cover structure 20 between the plates 88 and extends forward toward the front hitch 14 or 14 '. In the integral coupling mode shown in Figure 3, the upper part of the three-point hitch structure 14 'is connected by a link 94 to a perforated projection 96 on the member 92. The structure described above forms a frame arrangement of strong implement capable of supporting implements that present a heavy draw load and / or a high torsional force load on the tool bar 80.
The depth control and survey wheel assemblies 100 (Figures 1, 2 and 4) are mounted at selected locations on the tool bar 80 by the transversely adjustable clamps 102. Each of the assemblies 100 includes a wheel arm 104. connected in a pivot to a lower part of the clamp 102 for a vertical movement relative to the tool bar 80 by a hydraulic cylinder 106 (Figures 1 and 2) extending between the arm and the upper part of the clamp 102. Wheel assemblies 100 can be adjusted to any desired location along toolbar 80 to accommodate different tools for ground work and different tool configurations.
As shown in Figure 1, the ripper supports 110 are spaced at selected locations along the tool bar 80 by the transversely adjustable tool clamps 112. The clamps 112 facilitate the mounting of the supports 110 either backward or forward. forward of the tool bar 80. As shown, the supports 110 are mounted in an alternating pattern to provide good soil and waste flow characteristics. The openings 29 '(FIG. 1) can be provided to selectively direct the defibrated refuse relative to the supports 110. The backward offset of the tool bar 80 provides ample space for the forward offset supports 110. Even when the scraper supports are shown, numerous other tillage tools, including tools mounted on rigid handle and spring travel handle can also be attached to tool bar 80. A variety of towing implements, including disc threshing sections, threshing barbed or spiky tooth, fertilizer equipment, herbicides and insecticides, exchanger wheels, incorporation wheels, row formers and stem jaws can also be connected to toolbar 80. A second toolbar (not shown) can be screwed or welded to the implement if necessary to support the various tools of farming.
In the embodiments of the invention shown in Figures 2 and 4, the towing discs 120 and 120 'are connected to the tool bar 80 by means of the transversely adjustable drawbar members 124 and 126. The forward ends of the drawbars 124 and 126 are pivotally connected to the transversely adjustable drawbar clamps 134 and 136 mounted on the tool bar 80. The rear ends of the drawbars 124 and 126 are connected to the clamps 138 and 140 which are connected to the disk frames 142 and are adjustable transversely with respect to the frames. The downward limit structures 144 and 146 are also adjustably connected to the tool bar 80 and the disk frames 142 by the adjustable front and rear clamps 154 and 156. The front clamps 154 are transversely adjustable on the tool bar 80 between the tool clamps 112. The rear clamps 156 are transversely adjustable over the disk frames 142. As shown in Fig. 2, the bottom limit structures include a main link 160 connected in a pivot to a short link 161 in a pivot point 162. The opposite end of the link is pivotally connected at point 164 to clamp 154 for rotation between a downward limit position from right to left (figure 2) and a raised position from left to right . The rear end of the link 160 is perforated at point 165 and is pivotally connected to a vertical clamp 166 to limit the lowermost position of the disks 120 relative to the frame 80. The lowermost position of the disks 120 can be adjusted by changing the opening 165 which is aligned with and screwed to a corresponding opening in the clamp 166.
The implement described above has good garbage handling characteristics and can operate under heavy residue conditions without clogging. The compact and strong frame structure includes the rear toolbar 80 and accommodates numerous implement combinations with the shredder, including deep-tilling tools featuring high draft loads and high toolbar torque. The lifting wheels, tools and towing implements can be easily mounted on and removed from the tool bar 80 and adjusted transversely on the tool bar as necessary for different operating conditions. The implement is easily adaptable for use with either the trailer hitch structure 14 where the wheel assemblies provide virtually all of the lifting function or the integral three-point hitch structure 14 'where the hitch itself provides the lifting for the clamping and shredding tools. When the lifting wheel assemblies 100 are clamped, essentially the entire lifting structure is supported from the tool bar below the uppermost part of the roof structure.
Having described the preferred embodiment, it will be apparent that various modifications can be made without departing from the scope of the invention as defined in the appended claims.
