Description
Load transfer device for laterally offset collection and transfer of harvested
material to a transport vehicle
DESCRIPTION
The invention relates to a load transfer device for the laterally offset collection
and transfer of harvested material to a transport vehicle.
In agriculture, a wide variety of harvested material must be collected and
transported away. Inter alia, frequently stalk-type biomass, in particular in the form of
straw or other grass types, need to be collected from the fields and transported away.
Stalk-type biomass of this type can be wet, wilted and dry grass, that is hay, but also
grain straw.
It is widely practised to collect grain straw or other stalk-type by means of so-
called round balers and to compress them to bales. Round balers of this sort are usually
drawn by a tractor and driven via a PTO shaft of the tractor. Such round balers are for
example shown in DE 10 2011 109 890 A1 or in DE 33 13 883 A1.
In addition, it is also quite common to collect stalks directly, by means of drawn
loading vehicles suitable therefor, usually by means of drawing machines in the form of
tractors or similar, from the ground and then to transport them away with the same
loading vehicle. In order to facilitate this, such loading vehicles usually have collecting
units for collecting the harvested material from the ground and frequently also cutting
units for comminuting the connected harvested material. A disadvantage of this
procedure is that while the loading vehicle is used to transport the retained harvested
material away, it can no longer be used to collect further harvested material.
It is the task of the present invention to provide a solution by means of which
harvested material, in particular stalk-type biomass, can be collected and transported
away in an especially efficient manner.
This task is solved by a load transfer device, having the characteristics of claim 1,
for collecting and transferring harvested material, in particular stalk-type biomass, to a
transport vehicle. Advantageous embodiments with suitable and non-trivial further
developments of the invention are given in the dependent claims.
The load transfer device for the laterally offset collection and transfer of
harvested material, in particular of stalk-like biomass, to a transport vehicle comprises a
pivotable unit for picking up the harvested material from the ground in a laterally offset
manner and for conveying the harvested material to a shredding unit designed to shred
the harvested material, wherein the pivotable unit is pivotable between a use position
folded-out downward in the direction of the ground and laterally and a stowing position
folded-in upward and laterally. In addition, the load transfer device has a intermediate
store for receiving the shredded harvested material and a conveying device for
conveying the shredded harvested material out of the intermediate store to a load
transfer unit of the load transfer device, by means of which the shredded harvested
material can be conveyed into a load compartment, arranged laterally adjacent to the
load transfer device, of the transport vehicle, in particular over a load compartment wall
of the load compartment.
According to an alternative independent aspect of the invention, it can also be
provided that the load transfer device does not include the shredding unit. In this case,
the picked-up harvested material can be supplied by means of the pivotable unit
unshredded, in particular uncut, directly to the intermediate store. In this case, the
unshredded or uncut harvested material is then conveyed by means of the load transfer
device by means of the conveying device out of the intermediate store to the load
transfer unit and by means of this into the load compartment of the transport vehicle.
In the solution according to the invention it is thus provided that the load transfer
device assumes the collecting and transfer of the harvested material, wherein a
transport vehicle, which during the load transfer procedure drives next to the load
transfer device, can assume the actual transporting away of the harvested material. The
load transfer device according to the invention can thus be used quasi continuously for
collecting harvested material, in particular in the form of stalk-like biomass, for example
from a field, shredding it and storing it temporarily. Inasmuch as a transport vehicle
should happen to be in the vicinity, this can drive parallel to the load transfer device and
be filled by means of the load transfer unit of the load transfer device. If the transport
vehicle concerned, in particular its load compartment, is completely filled, then the next
transport vehicle can be driven up to the load transfer device in order then to fill this
transport vehicle.
During the exchange of the transport vehicles, by means of the load transfer
device, harvested material can continue to be collected from the ground, shredded and
conveyed into the intermediate store of the load transfer device. Only the conveying
device disposed in the intermediate store and the load transfer unit are stopped during
the exchange of the transport vehicles, wherein the harvested material can still be
picked-up and temporarily stored. Thus, there are no stand times or downtimes when
the transport vehicles are exchanged. In other words, by means of the solution
according to the invention it is thus possible for the load transfer device to be operated
continuously, for example drawn or carried by a tractor or another drawing vehicle, in
order to collect harvested material from the ground, to shred it and to store it
temporarily in its intermediate store. By avoiding unnecessary stand times or downtimes
of the load transfer device, very high surface performances are possible.
In addition, the solution according to the invention offers a further advantage.
When driving narrow cornerings, for example, a transport vehicle to be loaded by means
of the load transfer device does not need to drive close to the load transfer device, since
the load transfer is preferably halted prior to narrow cornerings, especially preferably
thus already during the driving on the straight, wherein the harvested material is further
picked up by means of the load transfer device and temporarily stored. As soon as the
load transfer device is again located on a straight path, the temporarily stored and
shredded harvested material can be passed to the transport vehicle. Thus, it can be
ensured that virtually no harvested material is lost, even when the most tight cornerings
need to be travelled by means of the load transfer device.
By means of the pivotable unit provided according to the invention, a drawing
vehicle drawing for example the load transfer device does not need to drive over the
harvested material to be picked up, e.g. disposed in the form of a so-called swath.
Instead, the drawing vehicle can drive in a manner which is laterally offset to the
harvested material to be picked up, while the pivotable unit, in its use position folded-
out downward in the direction of the ground and laterally, can pick up the harvested
material. In addition, the pivotable unit can also be designed to be relatively broad,
since it can be moved into its stowing position folded-in upward and laterally, in
particular for journeys on public roads. On public roads, the load transfer device is thus
not constructed to be broader than is legally permitted, wherein for example on a field
during the collection of the harvested material, an especially large working breath can
be realised by means of the lateral pivoting down of the pivotable unit. Furthermore,
there results by reason of the pivotable unit also a better visibility, for example in the
case of a driver of the tractor by means of which the load transfer device is drawn, while
the pivotable unit is disposed in its folded-out use position.
An advantageous embodiment of the invention provides that the pivotable unit
has a conveying device for conveying the harvested material to the shredding unit. The
conveying device of the pivotable unit can be for example a conveyor belt, by means of
which the harvested material can be conveyed in the direction of the shredding unit.
The conveying device can for example extend substantially across the entire breadth of
the pivotable unit, such that the harvested material can be picked up and conveyed over
a particularly generous area.
A further advantageous embodiment of the invention provides that in the use
position of the pivotable unit the conveying device of the pivotable unit and the
conveying device disposed in the intermediate store are flush with one another. For
example, the conveying device disposed in the intermediate store can have a scraper
floor. By means of the arrangement, preferably flush with one another, of the two
conveying devices, the picked up harvested material can be conveyed, in an especially
continuous manner and therewith also quickly, as required first to the shredding unit,
from this into the intermediate store and from there to the load transfer unit and finally
into the load compartment of the transport vehicle concerned. In this regard, the two
conveying devices convey preferably perpendicularly to the transport direction of the
load transfer device.
In a further advantageous embodiment of the invention, it is provided that the
conveying device disposed in the intermediate store has a scraper floor disposed in the
region of a loading surface of the intermediate store, by means of which the shredded
harvested material received in the intermediate store can be conveyed in the direction
of the load transfer unit. Other types of conveying devices are of course also possible.
Particularly by means of the scraper floor, the harvested material can be particularly
easily and reliably conveyed from the intermediate store in the direction of the load
transfer unit.
Additionally, it can be provided that the conveying device disposed in the
intermediate store has at least one metering roller disposed on a side, facing the load
transfer unit, of the intermediate store, by means of which metering roller the
harvested material present in the intermediate store can be conveyed in the direction of
the load transfer unit. Preferably, several of these metering rollers are disposed above
one another in vertical direction of the load transfer device. By means of the metering
rollers disposed above one another it is reliably possible to convey the shredded
harvested material in the direction of the load transfer unit in particular when the fill
level of the intermediate store increases.
According to a further advantageous embodiment of the invention, it is provided
that the conveying device disposed in the intermediate store has a wall delimiting the
intermediate store, which can be extended and retracted in the direction of the load
transfer unit. Preferably, the wall is supported pivotable about an axis which extends in
transverse direction of the load transfer device. For example, the wall can be pivoted by
means of hydraulic cylinders such that it is pivoted either away from the load transfer
unit or towards it. Thus, the receiving space of the intermediate store can be varied in
an especially simple manner. If the pivotable wall is pivoted in the direction of the load
transfer unit, the picked up and shredded harvested material in the intermediate store is
pushed into the engagement region of the load transfer unit. Alternatively, it is also
possible for the delimiting wall to be translationally movable as a whole in the form of a
type of push-wall, in order to bring the shredded harvested material received in the
intermediate store into the engagement region of the load transfer unit. Preferably, it is
provided that either a scraper floor or the delimiting wall is used, which can be extended
and retracted in the direction of the load transfer unit. The metering rollers are used
preferably in both cases. Basically, it is however also possible for scraper floors,
metering rollers and extendable and retractable walls to be used in combination.
A further advantageous embodiment of the invention provides that a press is
arranged upstream of the shredding unit for compacting the harvested material. If for
example grass is shredded by means of the shredding unit, in particular cut, thus by
means of the compression an especially high cut quality can be achieved. All in all, there
results by means of the press arranged upstream of the shredding unit an especially
simple and reliable shredding procedure with regards to the picked up harvested
material.
In a further advantageous embodiment of the invention, it is provided that the
press for compacting the harvested material is movable in the direction of the conveying
device of the pivotable unit. If the conveying device of the pivotable unit is for example
a conveyor belt, the press can be lowered from top to bottom in the direction of the
conveyor belt in order to compact or press harvested material lying on the conveyor belt
before said material is then conveyed, after running through the press, further in the
direction of the shredding unit, by means of which the compacted harvested material is
then for example chaffed or shredded or comminuted in another manner. A spacing
between the press and the conveying device can in this regard for example variably
adjustable, such that depending on the harvested material to be compacted and
subsequently to be shredded a suitable spacing between the press and the conveying
device can be set, as a result of which then also the degree of the compacting can be
precisely set. It is also possible for an area to be provided for pressing the harvested
material after the conveying device of the pivotable unit, that is with regard to the
conveying direction of the conveying device. In this case, the press can for example be
lowered in the direction of this area in order to press the harvested material before it
reaches the shredding unit.
A further advantageous embodiment of the invention provides that the pivotable
unit has a roller equipped with receiving tines for picking up the harvested material from
the ground. In other words, the pivotable unit can have a so-called pick-up unit by
means of which for example grass or similar can be especially easily picked up. If for
example the load transfer device is moved along and over a swath, harvested material
can be especially easily picked up by means of the roller equipped with the receiving
tines and preferably conveyed onto the said conveying device of the pivotable unit, by
means of which the picked up harvested material is then in turn conveyed in the
direction of the shredding unit.
A further advantageous embodiment of the invention provides that the pivotable
unit has a mowing unit for mowing and subsequently picking up the harvested material
from the ground. By means of the load transfer device, in this case thus also the
harvested material to be picked up can be previously mown and then picked up
simultaneously in one single working step. For example, it is also conceivable that the
roller equipped with the receiving tines and the mowing unit are designed to be
exchangeable, such that the pivotable unit depending on requirement can be equipped
with the pick-up system or with the mowing unit.
According to a further advantageous embodiment of the invention, it is provided
that the shredding unit has a rotatable roller equipped with conveying tines, which
interacts with fixed cutting blades, which are preferably disposed in channels. A
rotational axis of the roller extends in this regard preferably perpendicularly to the
conveying direction of the conveying device disposed in the intermediate store. As soon
as the roller equipped with the conveying tines is set into rotation, the conveying tines
convey the harvested material in the direction of the fixed cutting blades, as a result of
which the picked up harvested material is shredded and thereafter supplied to the
intermediate store.
A further advantageous embodiment of the invention provides that the shredding
unit has a chaff cutter. Also, by means of the chaff cutter it is possible to comminute the
picked up harvested material as desired. It can also be provided that the load transfer
device is designed such that the cutting rotor can be exchanged for the chaff cutter and
vice versa, such that depending on the harvested material to be shredded the most
suitable cutting unit can be put to use.
In a further advantageous design of the invention, it is provided that the load
transfer unit can be positioned in a folded-in non-use position and in a folded-out load
transfer position. For example, the load transfer unit can be formed from several
foldable segments which can for example by means of suitable hydraulic cylinders be
extended and retracted or folded-in and folded-out. Thus, for example, it is conceivable
for the load transfer unit in its folded-in non-use position to be folded onto the
intermediate store or even at least partially into it, such that in the non-use position the
load transfer unit can be stored in a compact manner with regard to the transverse
direction of the load transfer device and preferably also with regard to the vertical
direction of the load transfer device. If, then, the load transfer unit is required during
the operation of the load transfer device for filling the transport vehicle, the load
transfer device can for example in turn be folded-out hydraulically outwards and
upwards.
According to a further advantageous embodiment of the invention, it is provided
that the load transfer unit has a conveyor belt, a worm conveyor and/or a blower with a
conveying pipe attached thereto for conveying the shredded harvested material into the
load compartment of the transport vehicle. Thus, it is possible by means of the load
transfer unit to supply the shredded harvested material in a simple manner to the load
compartment of the transport vehicle concerned.
A further advantageous embodiment of the invention provides that the load
transfer device is a trailer, a superstructure for a vehicle, or a motor vehicle. In the case
of a trailer, the load transfer device can for example have an axle with wheels disposed
thereon and a tow bar, such that the load transfer device can be quite simply hung onto
a drawing vehicle, for example onto a tractor. Alternatively, it is also possible for the
load transfer device to be formed as a type of superstructure for a vehicle, such that the
load transfer device can be set for example onto a chassis or also onto a loading surface
of the vehicle concerned. Furthermore, it is also possible for the load transfer device to
be self-driving, that is to be designed as a motor vehicle.
Finally, a further embodiment of the invention provides that the load transfer
device has a connector for an auxiliary drive, in particular for a PTO shaft of a tractor.
This is in particular advantageous when the load transfer devices in the form of a trailer.
Via the connector for the said auxiliary drive, all assemblies of the load transfer device
can be driven in a simple manner.
Further advantages, characteristics and details of the invention result from the
following description of preferred embodiment examples as well as with reference to
the drawing. The characteristics and characteristic combinations previously mentioned
in the description as well as the characteristics and combinations shown alone
hereinafter in the description of the figures and/or in the figures can be used not only in
the respective given combination but also individually or in other combinations, without
straying beyond the remit of the invention.

transfer device, wherein the pivotable unit is shown with the mowing
unit in its stowing position folded-in upward and laterally.
In the figures, identical or functionally identical elements are labelled with the
same reference signs.
A first embodiment, drawn by means of a tractor 1, of a load transfer device 2 is
shown in a perspective view in figure 1. The load transfer device 2 includes a pivotable
unit 3 for the laterally offset picking-up of harvested material 4 from the ground and for
conveying the harvested material 4 to a shredding unit 5 designed for shredding the
harvested material 4. The pivotable unit 3 can be pivoted between a use position folded-
out downward in the direction of the ground and laterally, shown here, and a stowing
position folded-in upward and laterally.
The load transfer device 2 includes furthermore an intermediate store 6 for
receiving the shredded harvested material 4. In the intermediate store 6 is additionally
provided another conveying device 7 which can be seen first in figure 5, by means of
which the shredded harvested material 4 received in the intermediate store 6 can be
conveyed in the direction of a load transfer unit 8 of the load transfer device 2. The load
transfer unit 8 serves to convey the shredded harvested material into a load
compartment of a transport vehicle disposed laterally beside the load transfer device 2,
in particular over a load compartment wall of the load compartment.
In the presently shown example, the harvested material has already been mown,
wherein the harvested material 4 is disposed in the form of a so-called swath on the
ground. In that the pivotable unit 3 can be pivoted into the use position folded-out
downward in the direction of the ground and laterally, shown here, the tractor 1 can
drive laterally beside the swath 4, while the harvested material 4 is picked up by means
of the pivotable unit 3. For the actual picking-up of the harvested material from the
ground, the pivotable unit 3 includes a roller 10 equipped with receiving tines 9. For
picking up the harvested material 4, the roller 10 is set into rotation, wherein the
receiving tines 9 pick up the harvested material 4 and by means of the rotational
movement of the roller 10 convey the harvested material 4 onto a conveyor belt 11 of
the pivotable unit 3.
Preferably, the roller 10 and the conveyor belt 11 are driven coupled to one
another such that the conveyor belt 11 is driven as soon as the roller 10 is driven and
therewith set into rotation. The harvested material 4 conveyed onto the conveyor belt
11 is then conveyed in the direction of the intermediate store 6 and thereby in the
direction of the shredding unit 5.
Since the shredding unit 5 is disposed somewhat above the unit 3 which has been
pivoted downwards, the conveyor belt 11 has preferably on its end, facing the shredding
unit 5, a shape formed obliquely upwards. Thus, the harvested material can be
especially simply supplied to the shredding unit 5.
Within a tow bar 12 of the load transfer device 2 in the form of a trailer, a Cardan
shaft, not shown in more detail here, can be disposed, which can be connected to a PTO
shaft, also not visible here, of the tractor 1. This Cardan shaft can then in turn be used to
drive the shredding unit 5. In this regard, for example a further drive can be interposed
in order to drive the shredding unit 5. The Cardan shaft of the tractor 1 can additionally
for example also be used to drive the conveyor belt 11, the roller 10 and all other parts
of the load transfer device 2 which are to be driven.
In figure 2, the first embodiment form, driven by means of the tractor 1, of the
load transfer device 2 is shown in a further perspective view. The pivotable unit 3 is here
disposed in its stowing position folded-in upward and laterally. Furthermore, the load
transfer unit 8 has been moved also into a folded-in non-use position. The load transfer
unit 8 can for example have several segments which can be folded-in relatively to one
another, such that the load transfer unit 8 can be moved from the folded-out transfer
position shown in figure 1 into the folded-in non-use position shown here in figure 2. For
this, for example several unspecified hydraulic cylinders can be disposed on the load
transfer unit 8, such that the load transfer unit can be positioned depending on
requirement between the folded-in non-use position shown here and the folded-out
load transfer position shown in figure 1.
As can be seen, the load transfer unit is in its folded-in non-use position located
within the intermediate store 6 of the load transfer device 2, such that the load transfer
device 8 can be especially compactly accommodated. By means of the lateral folding-on
and pivoting-up of the pivotable unit 3 and by means of the described stowage of the
load transfer unit 8 within the intermediate store 6, the load transfer device 2 can be
moved also on public roads in a particularly problem-free manner, since the load
transfer device 2 is constructed especially compactly both in transverse direction and in
vertical direction by folding-in or folding-on the pivotable unit 3 and the load transfer
unit 8.
In figure 3, the first embodiment, drawn by means of the tractor 1, of the load
transfer device 2 is shown in a side view, specifically while the pivotable unit 3 has been
disposed in its use position folded-out downward in the direction of the ground and
laterally, in order to pick up the harvested material 4. The roller 10 equipped with the
receiving tines 9 drives over the harvested material 4 to be picked up and thus conveys
the harvested material 4 onto the conveyor belt 11 by means of which the harvested
material 4 is conveyed further to the shredding unit 5.
In figure 4, the area A labelled in figure 3 is shown in a detailed view. In this
representation, the harvested material 4 received onto the conveyor belt 11 of the
pivotable unit 3 can be seen easily while this is being conveyed in the direction of the
shredding unit 5. In the presently shown case, the shredding unit 5 has a rotatable roller
equipped with conveying tines which interacts with fixed cutting blades. The roller 5 has
on its outer periphery a plurality of conveying tines not specified here in more detail, by
means of which the harvested material 4 is conveyed in the direction of the fixed cutting
blades not shown here in more detail which are preferably disposed in respective
channels. The cutting blades then shred the harvested material 4. In regard of the
conveying direction of the conveyor belt 11, a hydraulic press 13 is arranged upstream
of the shredding unit 5. Before the harvested material 4 reaches the shredding unit 5,
the harvested material 4 is compacted by means of a hydraulic press 13. Thus, the cut
quality of the harvested material 4 can be increased.
In figure 5 is shown the first embodiment of the load transfer device 1 along the
cut plane B-B labelled in figure 3. In this cut representation, the previously mentioned
conveying device 7 can be seen which is disposed within the intermediate store 6. The
conveying device 7 can for example have a scraper floor. According to the present
representation, the harvested material 4 is thus conveyed by means of the conveyor belt
11 initially to the left in the direction of the hydraulic press 13, not designated here in
more detail, and from there further in the direction of the shredding unit 5 in the form
of a cutting rotor.
From the shredding unit 5, the shredded or cut harvested material 4 reaches the
intermediate store 6 and can be moved by means of the conveying device 7 further to
the left to the extended load transfer unit 8. The load transfer unit 8 can for example
have an integrated conveyor belt, not designated here in more detail, by means of
which the shredded harvested material 4 can be transported to a transport vehicle
which is not shown here. Thus, the shredded harvested material 4 can be conveyed out
of the intermediate store 6 for example over a load compartment wall of a load
compartment of the transport vehicle into said transport vehicle.
The team formed from the load transfer device 2 and the tractor 1 can thus drive
next to a transport vehicle while the harvested material 4 is picked up from the ground,
compacted, shredded and then conveyed into the transport vehicle. If the load
compartment of the transport vehicle has for example been completely filled, the load
transfer device 2 can continue to pick up and temporarily store harvested material 4 by
reason of its intermediate store 6, without needing to pass the harvested material 4 to a
transport vehicle.
The team formed from the load transfer device 2 and the tractor 1 can thus drive
on while for example a further still empty transport vehicle approaches and positions
itself during the approach next to the load transfer device 2. As soon as the transport
vehicle has been positioned with its load compartment laterally besides the load
transfer device 2 at a suitable position below the load transfer unit 8, for example the
said conveyor belt which is integrated in the load transfer unit 8 can be activated
together with the conveying device 7 in the intermediate store 6, in order to supply the
shredded harvested material 4 which has been temporarily intermediately stored in the
intermediate store 6 to the load compartment of the still empty transport vehicle.
In figure 6, the area C marked in figure 5 is shown in an enlarged detailed view. In
the present detailed view, the hydraulic press 13 and the shredding unit 5 in the form of
a cutting rotor are again easy to see. According to the present representation, the
received harvested material 4 is conveyed by means of the conveyor belt 11 of the
pivotable unit 3 to the left in the direction of the hydraulic press 13, by means of which
the harvested material 4 is initially compacted and subsequently only then shredded or
cut by means of the shredding unit 5.
In figure 7 is shown a second embodiment of the load transfer device 2 in a
perspective view while it is drawn by means of the tractor 1. The second embodiment of
the load transfer device 2 differs from the first embodiment of the load transfer device 2
only in that the pivotable unit 3 has a mowing unit 14 instead of the roller 10 equipped
with the receiving tines 9, whereby it is only possible to see a cover 15 of the mowing
unit 14, since the pivotable unit 3 is shown in its use position folded-out downward in
the direction of the ground and laterally.
The second embodiment of the load transfer device 2 is thus by reason of the
mowing unit 14 additionally in the position itself to mow the harvested material 4 to be
picked up. The mowing unit 14 then conveys the mown harvested material 4 in turn
onto the conveyor belt 11 of the pivotable unit 3, from where it reaches the
intermediate store 6 in the already described manner.
In figure 8, the second embodiment, drawn by means of the tractor 1, of the load
transfer device 2 is shown in a further perspective view, wherein the pivotable unit 3 is
disposed in its stowing position folded-in upwards and laterally. The load transfer unit 8
is, as already described in connection with figure 2, also disposed in turn in its folded-in
non-use position. In the present representation, the view onto the bottom side of the
mowing unit 14 is enabled.
In regard of the intended direction of travel, the load transfer unit 8 has been
shown disposed always to the right of the intermediate store 6 and the pivotable unit 3
disposed always to the left of the intermediate store 6. Of course, also a mirror image
arrangement can occur, in which the load transfer unit 8 is disposed on the left and the
pivotable unit 3 on the right of the intermediate store 6. It is important for the load
transfer unit 8 and the pivotable unit 3 to be disposed on opposite sides of the
intermediate store 6.
