Description

The present invention relates to a harvested goods and / or transport trolley with a loading space, which is delimited by a loading space floor and upright loading space walls, and a ladder for entering the loading space, which is movably mounted on one of the loading space walls and / or on the loading space floor.

Such agricultural harvested goods and / or transport wagons can in particular form loading wagons or chopping wagons, in the hold of which agricultural harvested goods such as grass, hay or straw can be temporarily stored and transported. A loading wagon usually has a pick-up device for picking up the crop from the ground, for example in the form of a pickup with a rotating spiked roller and / or a pick-up rotor, to which a cutting device can be assigned in order to convey the crop into the loading space and cut it, if necessary. Chopping wagons can possibly do without such a pick-up device and can be loaded from above using a blower tube or a conveyor belt from a harvesting device moving in parallel or in front.

Since such agricultural harvested goods and / or transport wagons have considerable dimensions, ladders are regularly provided for boarding the loading space, for example for maintenance and inspection work, in order to make it easier to get into the loading space. It is often not possible to get in via the open unloading flap, since the path through the unloading meter is blocked there, for example in the form of several metering rollers. In order not to have to climb completely over the upper edge of the side walls, an entry opening can be provided in one of the loading space walls, which can be closed by an entry door or flap. If the entrance door is open, a ladder attached to the entrance opening can be used to easily enter the loading space.

Such a loading wagon with an entry door into the loading space and an associated ladder is, for example, from the script DE 299 19 027 U1 known. The ladder is swivel-mounted under the entrance door on a side rail of the loading wagon so that the ladder can be folded against the closed door when the ladder is not needed. In order to get into the hold, the ladder is folded down and then the entrance door is opened.

The font also shows a loading wagon with a similar boarding ladder DE 20 2006 008 257 U1 . There, too, the ladder can be folded against the closed entrance door and folded down to enter the cargo hold. In order to be able to climb over a laterally protruding wheel axle or a mudguard attached there, the ladder is not hinged directly under the door to a longitudinal spar of the load compartment wall, but to an intermediate bracket that can be swiveled out to bridge the lateral protrusion of the mudguard.

Such entry ladders have so far been disadvantageous in various ways. In the case of larger loading wagons, the entry ladders are quite high so that they are difficult to access and difficult to unlock and, if this is done, can fold down in an uncontrolled manner, which entails a corresponding risk of injury to the operator. On the other hand, the ladder that is folded up prevents the unlocking of the entrance door, with chopped wagons and other bycatch, such as leaves and branches of brushed bushes, often accumulating on the ladder, which can further impair the unlocking of the entry ladder.

The present invention is therefore based on the object of providing an improved agricultural harvested goods and / or transport wagon of the type mentioned at the outset which avoids disadvantages of the prior art and advantageously develops the latter. In particular, simple and safe operation of the ladder is to be made possible without hindering the unlocking of an entry door which may be provided.

According to the invention, the above object is achieved by an agricultural crop and / or transport wagon according to claim 1. Preferred embodiments of the invention are the subject of the dependent claims.

It is therefore proposed that the ladder no longer be folded against one of the upright loading space walls, but instead stowed by pushing it into a storage space provided for the ladder. According to the invention, a ladder stowage space with a sliding guide for inserting the ladder into the ladder stowage space is provided on the loading space floor and / or on one of the loading space walls. The sliding guide enables the ladder to be simply pushed in or pulled out of the ladder storage space in the longitudinal direction of the ladder if the ladder is to be used. In the ladder storage space, the ladder is protected from contamination by chopped material and similar bycatch like leaves. At the same time, the risk of injury that existed when folding down previous ladders is averted.

The sliding guide mentioned can in principle be designed differently and advantageously comprises at least one guide profile extends along the ladder stowage space to guide the ladder along the longitudinal axis of the ladder stowage space as it is inserted and pulled out. Advantageously, two opposing guide rails can be provided and aligned parallel to one another in order to guide the conductors on opposite sides when inserting and withdrawing them, thereby better preventing the conductors from tilting.

In a simple development of the invention, said at least one guide profile could be adapted to the shape or cross section of the longitudinal bars of the conductors in order to guide the conductors themselves and to come into sliding engagement with the longitudinal bars of the conductors. For example, it would be conceivable to pull out the ladder completely and lean it against the load compartment wall at the desired point, and to push it back into the sliding guide after the work is done.

Advantageously, however, the sliding guide can also have, in addition to said guide profile, a guide slide which can be displaced along the at least one guide profile, the conductor being articulated on said guide slide. The guide profile itself guides the mentioned slide, which in turn holds the ladder.

Advantageously, the ladder can be articulated on said guide carriage in order to be pivoted relative to the guide carriage when pulled out and can be folded down onto the floor, for example. As an alternative or in addition, the articulated connection of the conductors to the guide carriage can also help prevent jamming or jamming when inserted into the conductor storage space.

As an alternative or in addition to the articulated connection of the conductors to the guide carriage, the guide carriage itself can also be pivotable with respect to the guide profile, for example in that a rounded guide head of the carriage is rotatably inserted in a guide groove of the guide profile. The guide carriage can be pivoted relative to the guide profile about a pivot axis perpendicular to the direction of insertion, in particular about a horizontal pivot axis, in order to enable the conductors attached to it to pivot.

In an advantageous development of the invention, the said guide carriage, to which the ladder is articulated, can form an at least partially extendable step from the storage space, onto which a user entering the loading space can place his foot. The step mentioned can advantageously form an at least approximately lying step surface for a foot, so that the person can step onto the step.

In particular, the said guide carriage can be pulled out of the ladder stowage space in such a way that the part of the guide carriage protruding from the ladder stowage space forms a lying, at least approximately horizontal tread surface on which the ladder is then adjoined or fastened in order to safely move from the ladder to the step reach.

In order to reliably guide the ladder when it is inserted into the ladder stowage space and to prevent the ladder from flipping around, in an advantageous development of the invention, at least one further guide element spaced apart from the guide carriage can be provided on the ladder, which can be brought into sliding engagement with the at least one guide profile mentioned is when the ladder is inserted into the ladder storage space. The guide carriage can be pushed ahead into the ladder stowage space and the guide element mentioned on the ladder can then be brought into engagement with the guide profile when the ladder is pushed in a little, in order then to guide the ladder along a predetermined guideway when it is pushed in further.

Said conductor receiving space can advantageously form an insertion slot into which the conductor can be inserted in the longitudinal direction of the conductor and which surrounds the inserted conductor on at least three sides. Advantageously, said insertion slot can surround or encompass the conductors on four sides and have a slot cross section which is adapted to the shape of the conductor cross section and / or is somewhat larger than the conductor cross section.

Advantageously, the conductor receiving space mentioned is long enough to be able to receive the conductors completely. Depending on the required length, the said ladder can be telescoped and / or extendable by unfolding several ladder segments in order to simultaneously fit into the ladder stowage space mentioned.

In an advantageous development of the invention, the conductor stowage space mentioned can be formed under or in the loading space floor, the conductor stowage space advantageously being able to be oriented in a horizontal manner, in particular in such a way that the conductor can be inserted flat into the conductor stowage space.

Advantageously, the said ladder stowage space can extend with a longitudinal axis of the stowage space transversely to the direction of travel of the harvested goods and / or transport wagon, so that the ladder runs from a left or can be stowed under or in the load compartment floor.

Said loading floor can be equipped in a manner known per se with a floor conveyor, in particular scraper floor conveyor, in order to be able to distribute the crop picked up in the loading room and / or to convey it to an unloading opening. In particular, a scraper floor conveyor can be provided with endlessly rotating conveying means which convey the crop on the top of the loading space floor in the desired direction, dive down at the end of the loading space floor and run back under the loading space floor. For example, an endlessly circulating, preferably flexible, conveying means such as a conveyor cable, conveyor belt or conveyor chain can be driven in a rotating manner and can be provided with engagement means, for example in the form of scraper slats, which exert the desired conveying effect on the material to be conveyed.

If the floor of the loading space is provided with a floor conveyor in the manner mentioned, in an advantageous further development of the invention the said ladder stowage space can be arranged between an upper run and a lower run of the endlessly rotating conveyor. In particular, the aforementioned insertion shaft can extend transversely to the conveying direction of the floor conveyor between its circulating means. This allows the entry ladder to be stowed away in a particularly space-saving manner.

Advantageously, the said ladder and the ladder stowage space can be assigned to an entry opening which can be formed in one of the upright loading space walls. In particular, the ladder stowage space can be arranged under the said entry opening and / or the ladder can be pulled out under the entry opening in order to end in the pulled-out position with an upper end at a lower threshold of the entry opening. If the guide slide is provided in the aforementioned manner and is designed as a pull-out step on which the ladder is pivotably articulated, the said guide slide can be pulled out a little below the entry opening from the loading space wall and / or the loading space floor in order to create a step surface below the entry opening to form for the foot of a beginner. The ladder then leads from the step to the floor.

Said entry opening can be closed in a manner known per se by means of an entry door or flap, said door being pivotable about an upright or lying door pivot axis on the loading space wall or can also be moved laterally along the loading space wall as a sliding door. By stowing the ladder in the ladder stowage space described, in particular by pushing the ladder into the insertion slot, the stowed ladder does not hinder the opening of the entry door mentioned. In this respect, it is also possible to only open the entrance door without pulling the ladder out into its functional position, for example to be able to take a look inside the cargo space. Unlocking and / or actuating the entrance door is possible regardless of the position of the ladder and is not hindered by the ladder.

In a further development of the invention, the conductor storage space can be closed by a storage space cover if the conductor is sunk into the conductor storage space. Such a storage space flap can be fastened, for example, to one end of the ladder in order to automatically close the storage space opening when the ladder is pushed in. As an alternative or in addition, a storage flap which is pivotably mounted adjacent to the storage space opening can also be provided, or a completely separate closure lid can also be provided for the storage space.
