Description
Load transfer device for collecting and transferring harvested material to a
transport vehicle
DESCRIPTION:
The invention relates to a load transfer device for collecting and transferring
harvested material to a transport vehicle.
In lture, a wide variety of harvested material must be collected and
transported away. Inter alia, frequently 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 sed to collect grain straw or other stalk-type by means of socalled
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 t 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
g vehicle. In order to facilitate this, such loading vehicles usually have collecting
units for ting the harvested material from the ground and frequently also cutting
units for comminuting the connected harvested material. A antage 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 ted 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 ent 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 s, to a
transport vehicle. Advantageous embodiments with le and non-trivial further
developments of the invention are given in the dependent claims.
The load transfer device according to the invention for collecting harvested
material, in particular stalk-type biomass, and transferring it to a transport vehicle
comprises a collecting unit for collecting the harvested material from the ground.
Furthermore, the load transfer device has a g unit for comminuting the collected
harvested material. In addition, the load transfer device has a buffer store for receiving
the comminuted harvested material and a conveying device for conveying the
comminuted harvested material out of the buffer store to a load transfer unit of the
load transfer device, by means of which the comminuted harvested material can be
ed 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. Laterally adjacent to the load transfer device denotes that the load
transfer unit is designed to convey the harvested al laterally, in respect of a use-
appropriate drive direction of the load transfer , in particular a forwards drive
direction, onto a te vehicle in the form of the transport e. The load er
device is thus neither a part of the transport vehicle nor a part of a rig to which the
ort vehicle belongs. The ort vehicle itself includes preferably no loading or
receiving on of its own for harvested material.
According to an alternative independent aspect of the invention, it can also be
provided that the load transfer device does not include the g unit. In this case, the
conveying unit can convey the harvested material into the buffer store without it being
cut. In this case, the uncut harvested material is then conveyed by means of the load
transfer device by means of the conveying device out of the buffer 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, n a
transport e, 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 al for example from a field, comminuting it and storing it
temporarily, in particular in the form of stalk-like biomass. Inasmuch as a transport
vehicle should happen to the 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 ned, in particular its load compartment, is completely filled,
then the next transport vehicle can be driven up to the load transfer device in order to
be filled. During the exchange of the transport vehicles, the collecting unit and the
cutting unit of the load transfer device can be operated further, such that the harvested
material can be further collected from the floor, comminuted and ed into the
buffer store of the load transfer device. Only the conveying device and the load transfer
unit are stopped during the exchange of the ort vehicles, wherein the harvested
material can still be retained 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 er device to be
operated continuously, for example drawn or carried by a tractor or another drawing
e, in order to collect harvested al from the ground, to ute it and to
store it temporarily in its buffer 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. For
example, when driving narrow cornerings, 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 ted material is further
taken 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 conveying device and the
load transfer unit can be again activated in order to transfer the temporarily stored and
comminuted harvested material to the transport vehicle. Thus it can be ensured that
lly no or absolutely no harvested material is lost, even when the most tight
cornerings need to be travelled by means of the load transfer device. All in all, it is thus
possible by means of the load transfer device according to the invention aneously
to collect harvested material, to cut it into the desired , to store it temporarily and
to transfer it to a transport vehicle.
An advantageous embodiment of the invention provides that the activation of the
conveying device and the activation of the load transfer device are coupled to one
another. The coupling can be realised both mechanically and also with control
technology. “Coupled” means that as soon as the conveying device is activated, that is,
is switched on, the load transfer unit is automatically also activated. Thus, if
comminuted harvested material taken up by activating the conveying device in the
buffer store is conveyed into an access area of the load transfer unit, thus the
comminuted harvested al is automatically conveyed r as fast as possible in
the direction of the relevant transport vehicle by reason of the coupled activation of the
load transfer unit. In the same way, also the deactivation of the conveying device can be
coupled to a deactivation of the load transfer unit, wherein this can in the same way be
ed ically or with control technology. An unnecessary ion of the load
transfer unit can thereby be prevented, since when the conveying device is deactivated,
at the latest after a certain time there will be no comminuted harvested material
present in the access area of the load transfer unit.
A further advantageous embodiment of the invention provides that the operation
of the collecting unit and cutting unit is decoupled from the operation of the conveying
device and the load transfer unit. As previously already mentioned, it is thus le for
the load transfer device to be able to continuously t harvested material from the
ground and comminute it and thereby supply it to the buffer store, without the
conveying device and the load transfer unit needing to be activated. As in the initially
mentioned example, it is thus for example possible for a change from a ort vehicle
onto the other transport vehicle to be undertaken simply, wherein the load transfer
device further collects and comminutes harvested material during the exchange. As
soon as the exchange of the transport vehicles has been completed, the ing
device and load transfer unit, which can be operated independently from the collecting
unit and cutting unit, can be activated, such that the harvested material which has
meanwhile been temporarily stored in the buffer store and comminuted can be
conveyed in the ion of the load er unit and by means thereof can be
conveyed into the load compartment of the transport vehicle. The load transferring of
the temporarily stored harvested material into a transport vehicle can thus be d
at any time when required, wherein the load transfer device can furthermore be
continuously used to collect harvested material from the ground, to comminute it and to
temporarily store it in its buffer store. The load transfer device can thus be continuously
used to collect harvested material from the ground, to comminute it and to temporarily
store it, as a result of which very high surface performances are possible with the load
transfer device.
According to a r advantageous embodiment of the invention, it is ed
that the load transfer unit has a detecting device, which is ured to detect whether
the load transfer unit is disposed in a designated load transfer positioning relatively to
the load compartment of the transport vehicle. The ing device can for example
have an optical sensor, a radar , an ultrasound sensor or the like, by means of
which it can be determined in a reliable manner whether the load transfer unit has been
disposed in a designated load transfer positioning vely to the load compartment of
the transport vehicle, in which harvested material can be conveyed from the load
transfer device into the load compartment of the ort vehicle without loss or at
least with as little loss as possible by means of the load transfer unit. Thus, it can be
ensured in a reliable manner that no harvested material is lost at the load transfer into
the load compartment of the transport vehicle. Preferably, the activating of the load
er unit for conveying the comminuted harvested material into the load
compartment is coupled thereto, that the load transfer unit has been disposed in its
designated load transfer oning relatively to the load compartment of the ort
vehicle. The detecting device, which is configured to detect whether the load transfer
unit is disposed in its designated load transfer positioning, can for example be coupled
using signal technology with a control of the load transfer device, which control is
configured to activate the load transfer unit only when it has been detected that the
load transfer unit is disposed in its designated load transfer positioning relatively to the
load compartment of the transport e. In addition, the control device can also be
configured to deactivate the load transfer unit as soon as it is determined that the
designated load transfer oning relatively to the load compartment of the transport
vehicle has been left. It can thereby be ensured that the load transfer of the retained
harvested al from the load transfer device into the load compartment of the
transport e starts only when the load transfer unit has also been correctly
positioned, wherein preferably the load er of the harvested material into the load
compartment is halted as soon as it is detected that the designated load transfer
oning of the load transfer unit relatively to the load compartment of the transport
vehicle has been left.
In a further advantageous embodiment of the invention it is provided that the
load er device has a detecting device which is configured to detect whether the
buffer store has reached a predetermined maximum fill level. Furthermore, this
ing device can also quite generally be configured to detect a filling level of the
buffer storage per se. For the detecting of the fill level of the buffer store, the detecting
device can have for example l sensors, such as a camera system or the like, also
other s suitable therefor. Preferably, a control device of the load transfer device is
suitable for transmitting a signal to a drawing vehicle pulling the load transfer device or
ise orting it, e.g. to a tractor, when the maximum fill level has been
reached. The signal can in the simplest case be a warning , as a result of which an
optical and/or acoustic warning is outputted by means of the drawing vehicle. A driver
of the drawing vehicle is thus made aware that the maximum fill level in the buffer store
has been d and this should at the moment not further be filled until it has been
emptied to some extent. For example, as a warning signal it can be outputted that the
driver should first stop the drawing vehicle. Alternatively, or onally, the signal can
also have the effect that the drawing vehicle is automatically stopped or decelerated. If,
thus, the maximum fill level in the buffer store should have been reached, it is also
possible that the drawing vehicle is automatically stopped or at least decelerated. Thus,
an overflow of the buffer store can be reliably prevented. By means of the mentioned
measures it can be ensured that – if the buffer store is actually full - no further
harvested material is collected from the ground and/or uted and therewith
supplied to the buffer store.
A further advantageous embodiment of the ion provides that the load
transfer unit can be positioned in a folded-in non-use position and in a folded-out load
transfer position. Preferably, the load transfer unit is designed such that in its folded-out
load transfer position, load er heights of 4.5 m can be reached, such that also
correspondingly high load compartment walls of load compartments of transport
vehicles can be overcome. In that the load transfer unit can be positioned ably
between its folded-in non-use position and its -out load transfer position, the
road traffic tions can be complied with. For in the folded-in non-use position, the
load transfer unit is preferably disposed lower than in the folded-out load transfer
position, wherein in the folded-in non-use position the load transfer unit is also laterally
folded in so far that a maximum width permissible in road traffic is not ed.
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 having
a conveying pipe ted thereto for conveying the comminuted harvested material
into the load compartment of the transport vehicle. Preferably, the load transfer unit for
conveying the comminuted harvested al has only one type of conveying means –
be it a or belt, a worm conveyor or a blower. Alternatively, however, it is also
possible for these conveying possibilities to be combined with one another. By means of
ing means suited to the harvested material to be collected and transferred, an
especially efficient operation of the load transfer device can be ensured.
According to a further ageous embodiment of the invention, it is provided
that the conveying device has at least one scraper floor disposed in the region of a
loading surface of the buffer store, by means of which scraper floor the comminuted
harvested material ed in the buffer store can be conveyed in the direction of the
load transfer unit. The scraper floor consists preferably of in each case two chain
strands, which are moved on a load receiving side by a pocket wheel. On two evenly
driven chains, carrier strips are mounted at regular intervals for conveying the harvested
material. By means of such scraper floors, in ular loose, geneous harvested
goods can be ally well conveyed.
In a further advantageous embodiment of the invention, it is provided that the
conveying device has at least one metering roller disposed on a side, facing the load
transfer unit, of the buffer store, by means of which metering roller the comminuted
harvested material in the buffer store can be conveyed in the direction of the load
transfer unit. ably, 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 possible in a le manner, in particular with an
increasing fill level of the buffer store, to convey the comminuted harvested material in
the direction of the load transfer unit.
A further advantageous embodiment of the invention provides that the conveying
device has a wall delimiting the buffer store, which wall can be ed and ted
in the direction of the load transfer unit. Preferably, the wall is mounted pivotably about
an axis which extends in transverse direction of the load transfer device. For e,
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, in an especially simple manner, the
load compartment of the buffer store can be varied. If the pivotable wall is pivoted in
the direction of the load transfer unit, the harvested material stored in the buffer store
and comminuted is pressed into the access area of the load transfer unit. Alternatively,
it is also le for the limiting wall to be translationally movable for example as a
whole in the form of a type of displacement wall, in order to bring the comminuted
harvested al retained in the buffer store into the access area of the load transfer
unit. Preferably, it is provided that either the scraper floor or the limiting wall is used,
which can be extended and retracted in the direction of the load transfer unit. The
metering rollers are preferably used in both cases. Basically, however, it is also possible
for scraper floors, metering rollers and extendable and table walls to be used in
ation.
Furthermore, it is provided ing to a further advantageous embodiment of
the invention that the load transfer device has for the supply of energy an interface for a
power take-off of a drawing vehicle. Thus, all units which need to be supplied with
energy can be supplied with energy via the power take-off of the drawing vehicle.
The load transfer device can be a trailer, an ly which can be mounted on a
motor vehicle, or a motor vehicle. It is thus possible for the load er device to have
a chassis and a r but no drive of its own, and to be drawn by means of a drawing
vehicle, for example by means of the tractor. In addition, it is also possible for the device
to have no chassis of its own and for example to be carried by a tractor or another
driven vehicle, e.g. by means of a device carrier present on the vehicle concerned. For
this case, the load transfer device can have corresponding mechanical interfaces, such
that it can be mounted e.g. on a three-point power lift, also known as a three-point
lic, such that the load transfer device as auxiliary equipment can for example be
coupled onto a tractor and lifted up. Furthermore, the load transfer device can also have
its own s and its own drive, that is be in the form of a motor vehicle and therewith
a self-driving machine. For the case that the load transfer device is in the form of a
r or a motor vehicle, it can be provided that one wheel of the load transfer device is
laterally able and retractable. In particular when the load transfer device is
laterally extendable, the extendable wheel is an advantage. A shifting of the centre of
gravity of the load transfer device caused by the extending of the load transfer unit can
thus be sated.
Further advantages, characteristics and details of the invention result from the

In the figures, cal or functionally identical elements are labelled with the
same reference signs.
Two rigs 1, 2 are shown in a perspective top view in figure 1. The first rig 1
includes a tractor 3 by means of which a load transfer device 4 in the form of the trailer
is drawn along a swath 5. The term "swath" is used to describe the crop that is
harvested in rows, in which grass or grain, in particular, but also other crops, are
harvested together or deposited (swathed), for example when sugar beet leaves are
used as feed. The swath 5 is preferably heaped-up stalk-type harvested material which is
taken up by means of the load transfer device 4, is uted, temporarily stored and
transferred to a transport vehicle 6, more precisely to a load compartment of the
transport e 6 of the second rig 2. The transport vehicle 6 can for example be a
tipper or push-off truck, which is drawn by means of a r r 7.
By means of the load transfer device 4, harvested material can be collected
continuously along the swath 5, comminuted and temporarily stored. Preferably, the
temporarily stored and comminuted ted material is transferred by means of the
load transfer device 4 over a lateral load compartment wall of the load compartment of
the transport vehicle 6, as long as the two rigs 1, 2 drive next to one another in a straight
line. As soon as there is a particularly tight cornering ahead, the load transfer of the
comminuted harvested material to the transport vehicle 6 is , wherein the load
transfer device 4 is moved further along the swath 5 and continuously collects,
utes and temporarily stores the harvested material.
In figure 2 is shown a first embodiment of the load er device 4 and a
perspective view, while it is drawn by means of the tractor 3. The load transfer device 4
includes a collecting unit 8 for collecting harvested material, preferably stalk-type
biomass, from the ground. The ting unit 8 is usually also described as a so-called
pick-up. The ting unit 8 can have a roller or roll, not seen in more detail here, on
which several radially protruding tines can be fastened, which can be set into rotational
nt in order to collect harvested material along the swath 5 shown in figure 1.
Alternatively, the collecting unit, unlike in the present representation, can also be a
mowing device by means of which fresh fodder can be mowed and collected up.
Furthermore, the load er device 4 includes a cutting unit 9 which can have
for example a cutting and conveying rotor. The cutting unit 9 can inter alia have a
r cutting mechanism, e.g. in the form of an adjustable knife mechanism, wherein
this can ably be jacked in or jacked out via a corresponding mechanism. In the
-in state, the cutting mechanism can comminute the supplied harvested material,
wherein in the jacked-out state the harvested material is not comminuted. The cutting
mechanism acts together with the cutting and conveying rotor.
By means of the collecting unit 8, collected harvested material is supplied to the
cutting unit 9, by means of which the retained harvested material can be cut to a
desired length. Furthermore, the load transfer device 4 has a further buffer store 10 for
the reception of the comminuted harvested material. By means of the g unit 9,
comminuted harvested material automatically reaches the buffer store 10.
At the rear end of the load er device 4 is d a load er unit 11
which serves to convey the comminuted and retained harvested material laterally over a
load compartment wall of the load compartment into the transport vehicle 6. In the
presently shown embodiment of the load transfer device 4, the load transfer unit 11
includes a conveyor belt, not shown in more detail, or l conveyor belts, in order to
convey the comminuted harvested material in the direction of the transport vehicle 6.
In addition, the load transfer device 4 has l metering rollers 12 disposed
above one another, which serve to convey comminuted harvested material retained in
the buffer store 10 in the direction of an access area 13 of the load transfer unit 11.
Thus, as soon as for example the two rigs 1, 2 drive next to one another parallel and in a
straight line, the metering rollers 12 can be activated, as a result of which harvested
material retained in the buffer store is conveyed in the direction of the load transfer unit
11, wherein by means of the said conveyor belts the harvested material is conveyed into
the transport vehicle 6.
The load transfer device 4 has in the present case only one axle, wherein a left
wheel 28, d on the axle, which is disposed on the same side on which the load
transfer unit 11 protrudes laterally beyond the load transfer device 4, can be laterally
extended and ted. As is described in still more detail hereinafter, the load transfer
unit 11 can be moved between the folded-out load transfer position shown here and a
folded-in non-use position. By means of laterally extending the wheel 28, the centre of
gravity of the load transfer device 4, which is here d when the load transfer device
is folded-out, can be compensated. This laterally extendable and retractable wheel 28
can be used in all embodiments of the load transfer device 4.
In figure 3 is shown the rig 1 in a perspective back view. In the present
representation, inter alia, the ement of the metering rollers 12 can again easily be
seen, which quasi delimit the buffer store 10 to the rear. The previously already
mentioned access area 13 of the load transfer unit 11 forms for its part a type of
reservoir into which the uted harvested material retained in the buffer store 10
can be conveyed by means of the metering rollers 12. In the access area 13, for example,
can be disposed one of several conveyor belts which belongs to the load transfer unit
11.
In figure 4 is shown the first embodiment of the load transfer device 4 er
with the r 3 serving as drawing vehicle, shown in a side view. As can be seen, the
load transfer device 4 is relatively high in particular by reason of the load transfer unit
11. By means of the load transfer unit 11, load transfer heights of preferably maximum
4.5 m can be overcome. Thus, tippers or push-off trucks in the form of the ort
vehicle 6 can be loaded reliably from above over a lateral load compartment wall from
above by means of the load transfer unit 11.
In figure 5, the load transfer device 4 is shown in a back view, wherein the load
transfer unit 11 is oned in its folded-out load transfer position. The load transfer
unit 11 includes inter alia two segments 14, 15 which are connected with one another
able to be pivoted in relation to one another. The segment 15 is in addition mounted
bly on the remaining load transfer device 4. The pivot axes of the segments 14, 15
all extend in the udinal direction of the load transfer device. By means of several
hydraulic cylinders 16, it is possible to pivot the segments 14, 15 relatively to one
r and in on to pivot the segment 15 in relation to the load transfer device 4.
As a result, the load transfer unit 4 can be positioned in the folded-out load transfer
position shown here. The wheel 28 is shown here still in its inner position, wherein this
can be extended laterally as already described above. In the present representation it
can easily be seen that in this folded-out load position of the load er unit 11, the
centre of gravity of the entire load transfer device is not located between the left wheel
28 and the right wheel 29. The left wheel 28 can be extended so far to the left that the
centre of gravity of the load transfer device 4 in regard of the transverse direction of the
load transfer device 4 is located at least ntially centrally between the two wheels
28, 29. As a result, the load transfer device 4 stands and drives in an especially stable
manner.
In figure 6 is shown the load transfer device in a further back view, n the
load transfer unit 4 has now been disposed in its folded-in non-use position. As can be
seen, the two segments 14, 15 can be folded to one another by operating the hydraulic
er 16, wherein the entire load transfer unit 11, in particular the segment 15, can
be folded-in laterally in the direction of the load transfer device 4. In the folded-in nonuse
position shown here, the load transfer unit 11 does not de laterally beyond
the rest of the load transfer device and is in addition ed d. The folded-in
non-use position can in particular be assumed when the load transfer device 4 is to be
moved via public roads. The left wheel 28 can then be retracted further to the inside,
since in the -in non-use position the centre of gravity of the entire load transfer
device 4 is substantially situated between the two wheels 28, 29 when the left wheel 28
has been laterally retracted.
In figure 7, the first embodiment, drawn by the r 3, of the load transfer
device 4 is shown in a further perspective view, wherein a pivotable wall 17, which
delimits the buffer store 10 in the direction of the tractor 3 has been folded in the
ion of the load transfer unit 11. In addition to the previously already mentioned
metering rollers 12, the wall 17 is also a part of a conveying device of the load transfer
device 4, which serves to convey harvested material buffer store 10 to the access area
13 of the load transfer unit 11. The wall 17 delimiting the buffer store 10 is at its bottom
end pivotably mounted about an axis extending in transverse direction of the load
transfer device 4. On the left side and on the right side are provided hydraulic cylinders
by means of the operation of which the wall 17 can be folded in the direction of the
tractor 3 and in the direction of the load transfer unit 11. By the pivoting or folding of
the wall 17, harvested al retained in the buffer store 10 can in a simple manner be
conveyed into the access area 13 of the load transfer unit 11.
In figure 8 is shown a second embodiment of the load er device 4 driven by
the tractor 3 in a perspective view. The embodiment, shown here, of the load transfer
device 4 differs from the first embodiment of the load transfer device 4 inter alia by the
fixed wall 19. The load transfer device 4 thus no longer has the pivotable wall 17.
In figure 9 is shown the second embodiment of the load transfer device 4 in a
partially cut side view. As can be seen, also the second embodiment of the load transfer
device 4 has a ity of metering rollers 12 disposed above one another, by means of
which harvested material retained in the buffer store 10 can be conveyed in the
direction of the load er unit 11. In addition, the embodiment shown here of the
load transfer device 4 includes a scraper floor 20 disposed in the region of a loading
surface, not specified in more detail, of the buffer store 10. By means of the scraper
floor 20, harvested material retained in the buffer store 10 can be orted in the
direction of the load transfer unit 11. The metering rollers 12 disposed above one
another support the conveying of the harvested material from the buffer store 10 into
the access area 13 of the load transfer unit 11.
An area A of the buffer store 10 is additionally shown in an enlarged view. In the
area A is mounted a fill level sensor 21 which is configured to monitor a fill level of the
buffer store 10 or at least to establish if the buffer store 10 has reached a
predetermined maximum fill level. The fill level sensor 21 thus serves as a detecting
device which is configured to detect how full the buffer store 10 has currently been
filled. For example, the fill level sensor 21 can send data concerning the actual fill level
of the buffer store 10 to a receiving unit 22. Where necessary - that is if the buffer store
is full - this can send e.g. a signal to the tractor 3, as a result of which this is
automatically halted or decelerated. Alternatively or additionally, the receiving unit 22
can send for example also a warning signal to the tractor 3, as a result of which an
optical and/or acoustic warning is outputted in the cabin of the r 3 which indicates
to the driver that the buffer store 21 has just reached its m fill level.
In figure 10 is shown the second ment of the load transfer device 4 in a
back view, while it is used to fill the transport vehicle 6. On the segment 14 of the load
transfer unit 11 is d an area B, which is shown additionally again enlarged. On the
segment 14 of the load transfer unit 11 is mounted a detecting device 23 which can have
a on sensor By means of this can be ished whether the load transfer unit 11,
more precisely the segment 14, is disposed in a designated load transfer positioning
relatively to the load tment of the transport vehicle 6.
In on, the detecting device 23 can alternatively or additionally have one
further receiver which can receive signals from a sender, not specified in any more
detail, which is mounted on the transport vehicle. For example, by evaluating the signal
strength of the retained s, the receiver of the detecting device 23 can determine
how close to the transport vehicle the second 14 of the load transfer device 11 is
disposed. It is especially advantageous when it receiver and the position sensor are
utilised in combination with one another. As a position sensor, for example, a vely
nsive ultrasound sensor can be used instead of a camera . By means of the
position sensor, it needs only to be detected whether the segment 14 of the of the load
transfer unit 11 has been disposed per se above the rig 1, in contrast to which the
receiving unit can ine by evaluating the retained signal whether the load transfer
unit 11 is also ed actually above load compartment of the transport e 6.
If, on the other hand, the position sensor is to be used alone, an optical marker
can be applied e.g. to the right load wall, not specified here in more detail, of the
transport vehicle 6, which can be detected by means of the position sensor. The position
sensor can for example be an optical sensor e.g. in the form of a camera system or
similar. Other sensor types are however also le, by means of which it can be
detected in a reliable manner whether the load transfer unit 11 has been positioned
correctly with respect to the transport vehicle 6.
The load transfer device 4 can for example have a control device which is coupled
with the position sensor and/or the receiver. If the position sensor and/or receiver signal
that the load er unit 11 has been correctly positioned with respect to the transport
e 6, thus the control device can for example automatically activate the said
conveyor belts of the load transfer unit 11, as a result of which the transport vehicle 6 is
loaded with harvested material so long as the load transfer unit 11 is correctly
positioned with respect to the transport vehicle 6. Should it be determined that the
designated load transfer positioning has been left, thus, for example, they conveyor
belts of the load transfer unit 11 can be automatically stopped. Thereby it can be
ensured that no harvested material is lost.
The fill level sensor 21, the receiving unit 22 and the detecting device 23 having
the position sensor and/or the receiving unit have admittedly been described only in
connection with the second embodiment of the load transfer device 4. However, these
elements or units can also be combined with the other embodiments of the load
er device 4.
In figure 11 is shown a third embodiment of the load transfer device 4, drawn by
means of the tractor 3, in a perspective back view. This ment is distinguished by
the load transfer unit 11 having instead of conveyor belts a blower 24 and a ing
pipe 25 disposed thereon. By activating the blower 24, harvested material can be
conveyed out of the buffer store 10 into the conveying pipe 25 and thereby conveyed
also into the transport vehicle 6.
In figure 12 is shown a fourth embodiment, drawn by means of the tractor 3, of
the load transfer device 4 in a perspective back view. This embodiment is distinguished
by the load transfer unit 11 having two pipes 26, 27 pivotable to one another instead of
conveyor belts or the blower 24, and a worm conveyor which is not specified in more
detail. The worm or can for example be formed in two parts and extend within
the pipes 26, 27.
In figure 13 is shown the rig 1 in a top view, wherein the r 3 draws the
second embodiment of the load transfer device 4 already shown in figures 8 to 10. As
can be seen, the load transfer device 4 is disposed laterally offset to the tractor 3. On a
drawbar 30, a hydraulic er, not specified in more detail here, or also another
actuator can engage, by means of which the drawbar 30 can be pivoted in relation to
the r 3. The hydraulic cylinder can be part of the load transfer device 4. The
possibility of y letting the tractor 3 drive laterally offset to the load transfer device
is for example advantageous when the load transfer device 4 is equipped with a mowing
device not shown here in more detail, in order first to mow and then to take up
ted material which is to be taken up. In this case, it can be ensured by means of
the laterally offset driving that the tractor 3 does not flatten the harvested material to
be mown and to be taken up. If, in the case described, on the other hand the tractor 3
and the load transfer device 4 were not to drive laterally offset to one another but
rather flush in direction of , the r 3 would flatten the harvested material, and
the mowing device on the load transfer device 4 would no longer be able to cut the
flattened harvested material in an orderly manner. The pivotable drawbar 30 can be
utilised also in the case of the other embodiments of the load transfer device.
