The frame and skid mounting surfaces are adapted for mating connection with one another to substantially align the skid with the frame along a substantially vertical mounting plane. A pair of laterally-spaced, juxtaposed, vertically extending skid alignment features are defined by the frame mounting surface, and a skid-mounted alignment block extending from the skid mounting surface is adapted for insertion between and into operative engagement with the pair of skid alignment features for aligning the skid with the frame on the vertical mounting plane.

Description

FIELD OF THE INVENTION

This invention generally relates to agricultural product applicators, and more particularly to mounting of equipment on such applicators.

BACKGROUND OF THE INVENTION

Modern agricultural practices rely heavily on timely application of agricultural products such as fertilizers and chemicals. Some of these products are applied in dry form using dry product spreading equipment, and others are applied in liquid form using sprayers.

It is advantageous to mount the dry and liquid product application equipment on separate skids, that can be interchangeably mounted on the same product applicator. Such skid-mounted equipment is typically large in size and heavy, weighing as much as several thousand ponds. Lifting the skid-mounted equipment into place typically requires the use of some sort of lifting arrangement.

The equipment-carrying skid must be precisely aligned on the frame of the applicator to properly interface with hydraulic and electrical connections, and mounting hardware that secures the skid to the frame. Also, the skid-mounted equipment must be properly positioned and secured on the applicator to properly balance the large loads of the application equipment and product on the frame of the applicator, so that the applicator can safely operate while travelling over uneven terrain, nits, ditches and the like, during application of the agricultural product.

In the past, skid-mounted equipment had to be manually guided onto the frame of the applicator in such a manner that mounting holes and features were properly aligned, often while the skid was dangling from an overhead crane or lifting device. It is desirable to provide an improved apparatus and method for aligning skid-mounted application equipment onto the frame of an applicator, in a manner that is more precise and less cumbersome than in prior approaches.

BRIEF SUMMARY OF THE INVENTION

The invention provides an apparatus and method for aligning an equipment skid on the frame of an agricultural product applicator defining substantially mutually perpendicular fore-aft, transverse and vertical axes of the frame, by utilizing an alignment system having a vertically extending frame mounting surface defined by the frame, and a vertically extending skid mounting surface defined by the skid. The frame and skid mounting surfaces are adapted for mating connection with one another to substantially align the skid with the frame along a substantially vertical mounting plane. A pair of laterally-spaced, juxtaposed, vertically extending skid alignment features are defined by the frame mounting surface. A skid-mounted alignment block extending from the skid mounting surface is adapted for insertion between and into operative engagement with the pair of skid alignment features for aligning the skid with the frame along the vertical mounting plane.

The invention may take a variety of forms, such as a system for aligning an equipment skid on an agricultural product applicator, or an agricultural product applicator having an equipment skid and a frame adapted for alignment of the skid on the frame by a skid alignment system according to the invention. The invention may also take the form of a frame or a skid incorporating aspects of a skid alignment system according to the invention.

One form of the invention provides, a system for aligning an equipment skid on the frame of an agricultural product applicator defining substantially mutually perpendicular fore-aft, transverse and vertical axes of the frame. The alignment system may include a vertically extending frame mounting surface defined by the frame, and a vertically extending skid mounting surface defined by the skid, with the frame and skid mounting surfaces being adapted for mating connection with one another to substantially align the skid with the frame along a substantially vertical mounting plane. The frame mounting surface may define a pair of laterally-spaced, juxtaposed, vertically extending skid alignment features. The alignment system may also include a skid-mounted alignment block extending from the skid mounting surface and adapted for insertion between and into operative engagement with the pair of skid alignment features for aligning the skid with the frame along the mounting plane.

In an alignment system according to the invention, the frame and skid may be further configured for mating contact along a substantially horizontal mounting plane, and the skid-mounted alignment block may be configured to be brought into position between the alignment features of the frame mounting surface by moving the skid parallel to the horizontal mounting plane as the vertically extending mounting surfaces of the frame and skid are brought into contact with one another along the vertical mounting plane.

In some forms of the invention, the skid alignment features may be facing edges of spaced, substantially parallel, vertically extending frame-mounted alignment bars fixedly attached to the frame and extending outward from the mounting surface of the frame. In other forms of the invention, the skid alignment features may be facing edges of an alignment slot in the frame mounting surface, of facing edges of other structures fixedly attached to or formed integrally with the frame mounting surface.

In practicing the invention, the frame and skid may be further configured for mating contact along a substantially horizontal mounting plane, and the skid-mounted alignment block may be brought into position between the alignment features of the frame mounting surface by moving the skid parallel to the horizontal mounting plane as the vertically extending mounting surfaces of the frame and skid are brought into contact with one another along the vertical mounting plane.

Some forms of the invention may include a second pair of laterally-spaced, juxtaposed, vertically extending skid alignment features defined by the frame mounting surface, and a second skid-mounted alignment block extending from the skid mounting surface and adapted for insertion between and into operative engagement with the second pair of skid alignment features for aligning the skid with the frame along the vertical mounting plane. The second set of skid alignment features may be provided by facing edges of a second set of spaced, substantially parallel, vertically extending frame-mounted alignment bars fixedly attached to the frame and extending outward from the mounting surface of the frame.

In some forms of the invention, the vertical mounting plane may be defined by an aft-facing, substantially vertical surface of the frame, such that the frame and skid mounting surfaces align the skid along the fore-aft axis of the frame, and the frame-mounted alignment bars and skid-mounted alignment blocks align the skid transversely on the frame.

In various forms of the invention, after the skid is aligned on the frame by the alignment system, the skid may be secured to the frame by fastening arrangements disposed along and extending through one or both of the vertical and horizontal mounting planes.

Other aspects, objects and advantages of the invention will be apparent from the following detailed description and accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows an agricultural product applicator 10, comprising a skid 12 for mounting equipment on a frame 14 of the applicator 10. FIGS. 2 and 3 show the frame 14 and skid 12, respectively. As shown in FIG. 2, the frame 14 defines substantially mutually perpendicular fore-aft, transverse and vertical axes 16,18,20 of the frame 14.

As shown in FIGS. 2-7, the skid 12 and frame 14 are adapted for alignment of the skid 12 on the frame 14 by a method utilizing a skid alignment system 22 that brings together a vertically extending frame mounting surface 24 defined by the frame 14, and a vertically extending skid mounting surface 26 defined by the skid 12. The frame and skid mounting surfaces 24, 26 are adapted for mating connection with one another to substantially align the skid 12 with the frame 14 in the fore-aft direction along a substantially vertically extending mounting plane 28 including and defined by the frame mounting surface 24.

As shown in FIGS. 2 and 6, in the exemplary embodiment of the applicator 10, the skid alignment system 22 also includes left and right pairs (viewed from the aft end of the frame 14) of laterally-spaced, juxtaposed, substantially parallel, vertically extending skid alignment features, in the form of facing edges (30,32 and 34,36) of left and right pairs of frame-mounted alignment bars (38,40 and 42,44). The alignment bars (38,40 and 42,44) have aligned aft-facing surfaces that define and form part of the frame mounting surface 24.

As shown in FIGS. 3 and 4, the skid alignment system 22, of the exemplary embodiment of the applicator 10, further includes left and right skid-mounted alignment blocks 46,48 extending from the skid mounting surface 26 and adapted for insertion respectively between, and into operative engagement with the left and right pairs of frame-mounted alignment bars (38,40 and 42,44) for aligning the skid 12 transversely with the frame 14 on the vertically extending frame mounting plane 28.

As shown sequentially in FIGS. 4-7, in the exemplary embodiment of the agricultural product applicator 10, the frame and skid 14,12 are further configured for mating contact along a substantially horizontally extending mounting surface 50 of the frame 14, that defines and forms part of a substantially horizontally extending mounting plane 52. To align the skid 12 on the frame 14, the skid-mounted alignment blocks 46,48 are brought into position between the alignment surfaces provided by the facing edges (30,32 and 34,36) of the left and right pairs of alignment bars (38,40 and 42,44) by moving the skid 12 parallel to the horizontal mounting plane 52, as the vertically extending mounting surfaces 24,26 of the frame and skid 14,12 are brought into operative contact with one another. Alternatively, the skid-mounted alignment blocks 46,48 can be brought into position above the channels formed between the alignment surfaces provided by the facing edges (30,32 and 34,36) of the left and right pairs of alignment bars (38,40 and 42,44), and then the skid can be lowered along the vertical mounting plane 28, to bring the vertically extending mounting surfaces 24,26 of the frame and skid 14,12 into operative contact with one another.

Once the skid 12 is properly aligned on the frame 14, the skid 12 is secured to the frame 14 with fastening arrangements (not shown).

As illustrated in FIG. 6, the alignment bars (38,40 and 42,44) and/or the blocks 46,48 may include beveled edges 54, or be otherwise configured to assist in guiding the blocks 46,48 into proper position for aligning the skid 12 on the frame 14.

FIGS. 8-10 illustrate a first alternate embodiment of a skid alignment system 122, for aligning an equipment skid 112 on the frame 114 of an agricultural product applicator, in a similar manner to that described above with reference to the first exemplary embodiment of the applicator 10. The alternate embodiment of the alignment system 122 includes a frame mounting surface 124 defined by the frame 114, and a skid mounting surface 126 defined by the skid 112, with the frame and skid mounting surfaces 124,128 being adapted for mating connection with one another to substantially align the skid with the frame along a mounting plane 128 including and defined by the frame mounting surface 124.

A pair of laterally-spaced, juxtaposed, vertically extending skid alignment features are defined by opposite edges 134,136 of a slot 137 in the frame mounting surface 124. A skid-mounted alignment block 148 extends from the skid mounting surface 126 and is adapted for insertion between and into operative engagement with the pair of skid alignment features, formed by the edges 134,136 of the slot 137 for aligning the skid 112 with the frame 114 on the frame mounting plane 128. The skid alignment block 148 has sides 147,149 contoured to provide a pointed shape to the alignment block 148 for engaging the edges 134,136 of the slot 137 to facilitate guiding the skid 112 into alignment with the frame 114. As shown in FIG. 10, the slot 137 may be shaped to have a contour or dimension 160 that provides clearance for the alignment block 148 to allow the alignment block 148 to move, or float slightly, in a desired direction with the alignment block 148 engaging the edges 134,136 of the slot 137.

In similar fashion, FIGS. 11-13 illustrate an alternate embodiment of a skid alignment system 222, for aligning an equipment skid 212 on the frame 214 of an agricultural product applicator, in a similar manner to that described above with reference to the first exemplary embodiment of the applicator 10 and the first alternate embodiment of the skid alignment system 122.

The second alternate embodiment of the alignment system 222 includes a frame mounting surface 224 defined by the frame 214, and a skid mounting surface 226 defined by the skid 212, with the frame and skid mounting surfaces 224,228 being adapted for mating connection with one another to substantially align the skid 212 with the frame 214 along a mounting plane 228 including and defined by the frame mounting surface 224.

A pair of laterally-spaced, juxtaposed, vertically extending skid alignment features are defined by opposite edges 234,236 of a slot 237 located generally in the center of the frame mounting surface 224, A skid-mounted alignment block 248 extends from the skid mounting surface 226 and is adapted for insertion between and into operative engagement with the pair of skid alignment features, formed by the edges 234,236 of the slot 237 for aligning the skid 212 with the frame 214 on the frame mounting plane 228. The skid alignment block 248 has sides 247,249 contoured to provide a pointed shape to the alignment block 248 for engaging the edges 234,236 of the slot 237 to facilitate guiding the skid 212 into alignment with the frame 214. As shown in FIG. 13, the alignment block 248 may be shaped to have a contour or dimension 260 that provides clearance within the slot 237 for the alignment block 248, to thereby allow the alignment block 248 to move, or float slightly, in a desired direction with the alignment block 248 engaging the edges 234,236 of the slot 237.

From the foregoing description, it will be appreciated that the invention provides an improved apparatus and method for aligning skid-mounted application equipment onto the frame of an applicator, in a manner that is considerably more precise and less cumbersome than in prior approaches wherein skid-mounted equipment had to be manually guided onto the frame of the applicator in such a manner that mounting holes and features were properly aligned.
