ABSTRACT:
The present invention concerns a vehicle for application in agriculture, in particular a forage harvester or combine with an attached implement mounted on it.
BACKGROUND OF THE INVENTION
On forage harvesters, in particular, but also on combines, removable front harvesting attachments are being applied for the harvesting and recovery of crop, which are mechanically relatively costly and heavy. Such front harvesting attachments are, in particular, so-called corn pickers or corn mower-choppers. At present an ever greater effective width of the front harvesting attachments is desired for reasons of economy, in order to be able to harvest a field in shorter time and with fewer passes. A usual commercially available width is, for example, 6 m. Due to the great weight of the wider front harvesting attachments, known forage harvesters equipped with driven front wheels and steerable rear wheels that must perform at high power and therefore also exhibit great weight, in order to be able to operate together with the wide front harvesting attachments but nevertheless exceed the legally permitted axle load values on the front axle. In order to be able to apply such wide front harvesting attachments with the known two axle design, a completely new design concept would be required for a forage harvester. Similar problems can also occur with combines.
It is known to provide supporting wheels on relatively light weight pick-up devices. For example, EP-386 430-B1 reveals a crop intake arrangement for harvesting machines, a so-called pick-up with a take up drum, which is supported by wheels suspended on a full floating axle or walking beam attached by a pivotal connection; U.S. Pat. No. 4,463,546 shows a similar take up arrangement provided with support wheels, that is mounted on a combine and is used to take up grain crops previously cut and lying on the ground; and De-197 26 917-A shows a forage harvester with a pick-up also supported on wheels.
The problem underlying the invention is seen in the high axle loads of two-axle agricultural vehicles equipped with relatively wide and heavy attached implements.
SUMMARY OF THE INVENTION
The present invention relates to crop intake arrangements for harvesting machines.
An object of the invention is to provide at least one wheel for supporting the attached implement of a harvesting machine, having front and rear sets of support wheels, in order to reduce the load on the harvesting machine wheels so that, during operation over the road the danger of exceeding the maximum allowable axle loading is alleviated.
A more specific object is to provide, in conjunction with a harvesting machine attachment having a central section having foldable wing sections secured to its opposite sides, a pair of support wheels which are secured to opposite sides of the central section.
Yet another object of the invention is to provide, in accordance with another embodiment of the invention, a wheeled support that is selectively mountable between a harvesting attachment and the harvesting machine.
Still another object of the invention is to provide a harvesting machine attachment with connecting points for selectively receiving a wheeled dolly in supporting relationship to the attachment.
These and other objects of the invention will become apparent from a reading of the ensuing description together with the appended drawings.
