This invention generally relates to agricultural product applicators, and more particularly to removably mounting an agricultural product sprayer, having one or more foldable booms, on the chassis of an agricultural product applicator.
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 pounds. Lifting the skid-mounted equipment into place typically requires the use of some sort of lifting arrangement.
Liquid product application sprayer equipment typically includes foldable booms that may span 140 feet, or more, when extended. These booms are usually placed in their folded position during installation and removal of the skid mounted sprayer.
Prior skid-mounted sprayer equipment has not included provisions on the skid for securing the foldable booms during installation, removal, and off-machine storage of the skid mounted sprayer equipment. This has required the use of additional securing straps or snubbers, to hold the folded booms in a safe and desirable position during installation, removal, and off-machine storage. The necessity for such additional equipment makes the processes of installation, removal and storage of the sprayer increases the time and effort that is required to install and remove of the sprayer.
It is desirable, therefore, to have an improved method and apparatus for supporting the folded booms during the installation and removal process, and during off-machine storage of the sprayer. It is also desirable that such improved boom support methods and apparatuses be usable for supporting the folded booms when the sprayer equipment is mounted on the applicator. It is further desirable, in some instances, that such improved boom support methods and apparatuses include provisions for locking the folded booms in place to facilitate operation of the applicator and installation and removal of the sprayer.
The invention provides an apparatus and method for removably mounting an agricultural product sprayer, having at least one foldable boom, on an agricultural product applicator having a chassis adapted for removably receiving the agricultural product sprayer, by attaching the foldable boom to a skid adapted for operative, removable mounting on the applicator chassis. The skid further has a boom cradle adapted for supporting the foldable boom in a folded position when the skid is mounted on the chassis, and when the skid is separated from the chassis of the agricultural applicator. As a result of this configuration, installation and removal of the sprayer from the chassis is facilitated.
In some forms of the invention, the skid may include lifting arrangement attachment elements, adapted for attachment of a lifting arrangement for mounting the sprayer on, and removing the sprayer from the chassis. Some forms of the invention may further include a boom lock for securing the folded boom in the boom cradle.
The skid may define a longitudinal axis of the skid and a first end of the skid disposed along the longitudinal axis of the skid and adapted for attachment to the first end of the foldable boom. The boom cradle may be disposed at an opposite longitudinal end of the skid.
In some forms of the invention, the first end of the skid is a rear end of the skid, and the opposite end of the skid is a front end of the skid when the sprayer is mounted on the chassis of the applicator.
In some forms of the invention, where the sprayer includes left and right foldable booms, the skid may include left and right boom cradles adapted for respectively supporting the left and right foldable booms in their folded positions when the skid is mounted on the chassis and when the skid is separated from the chassis of the agricultural applicator.
In one form of the invention, an agricultural product sprayer is provided for an agricultural product applicator having a chassis adapted for removably receiving the agricultural product sprayer. The agricultural product sprayer includes a skid, according to the invention, adapted for operative removable connection to the applicator chassis, and further adapted for attachment to the skid of a foldable boom of the sprayer. The skid includes a boom cradle, according to the invention, adapted for supporting the foldable boom in a folded position when the skid is mounted on the chassis, and when the skid is separated from the chassis of the agricultural applicator.
The invention may also take the form of an agricultural applicator having a chassis including a bed adapted for removable mounting on the bed of an agricultural product sprayer having at least one foldable boom. The agricultural product sprayer includes a skid, according to the invention, adapted for operative removable connection to the applicator chassis, and further adapted for attachment to the skid of the foldable booms. The skid may include a boom cradle, according to the invention, adapted for supporting the foldable boom in a folded position when the skid is mounted on the chassis, and when the skid is separated from the chassis of the agricultural applicator.
A method, according to the invention, may include attaching the foldable boom of an agricultural product sprayer to a skid that is adapted for operative removable mounting on a chassis of an agricultural product applicator, with the skid including a boom cradle adapted for supporting the foldable boom in a folded position when the skid is mounted on the chassis, and when the skid is separated from the chassis of the agricultural applicator. The method may also include supporting the foldable boom in the boom cradle during mounting of the skid on, and removal of the skid from the applicator chassis.
In forms of the invention where the skid includes lifting arrangement attachment elements, adapted for attachment of a lifting arrangement for mounting the sprayer on, and removing the sprayer from the chassis, a method may further include attaching a lifting arrangement to the attachments of the skid for mounting the sprayer on and removing the sprayer from the chassis. Where the boom cradles include a boom lock for securing the folded boom in the boom cradle, a method may further include locking the folded boom to the boom to the boom cradle with the boom lock.
Other aspects, objects and advantages of the invention will be apparent from the following detailed description and drawings of exemplary embodiments of the invention.
The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention and, together with the description, explain the invention. In the drawings:
While the invention is described in connection with certain exemplary embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents within the spirit and scope of the invention.

As shown in
In the exemplary embodiment of the applicator 10 and sprayer 16, the first end 24 of the skid 22 is the rear end 24 of the skid 22, and the opposite end 32 of the skid 22 is the front end 32 of the skid 22 when the sprayer 16 is mounted on the chassis 12 of the applicator 10. It will be understood, however, that in other embodiments of the invention the proximal ends of the booms 16,28 may be mounted to the front of the skid 22, and the boom cradles be positioned at a rear end of the skid 22.
It will also be appreciated that, in the exemplary embodiment of the applicator 10 and sprayer 16, the skid 22 and its attached boom cradles 26,28 are adapted for respectively supporting the left and right foldable booms 18,20 in their folded positions when the skid 22 is mounted on the chassis 12. In addition, because the boom cradles 26,28 are part of the skid 22, they also provide support for the folded booms 18,20 while the sprayer 16 is being lifted off of, or on to the chassis 12 of the applicator 10, as shown in
