Description
Technical Field
The present invention relates to a travelable transport device.
Background
For transporting the self-propelled harvester, for example, trucks with a load surface and a load platform can be used as the mobile transport device, which load platform is attached to the load surface or connected to the load surface when loading and unloading is required, wherein the load surface can pivot about a pivot axis.
Furthermore, transport trailers are used as a mobile transport device for transporting at least one self-propelled harvester, which are equipped with a loading surface and a loading platform (Rampe), wherein the loading platform can pivot about a pivot axis and has an upper side and a lower side, the upper side being travelable by the harvester. These transport trailers are towed by a towing vehicle, such as a truck or the like.
A truck for transporting a harvester is for example disclosed in document US 3,550,801A.
A transport device implemented as a transport trailer is disclosed by document US4,607,996A. The transport trailer is configured for transporting an agricultural harvester, wherein the agricultural harvester is positioned on a transport vehicle transverse to a longitudinal axis of the transport vehicle. For this purpose, the pivotable loading dock is arranged laterally on a load surface which extends parallel to the longitudinal axis of the transport vehicle.
When transporting a self-propelled harvester over a long distance to an area with poor infrastructure by means of a truck or transport trailer, problems may arise in that it is necessary to carry the running materials together. The carrying together of the running raw materials can take place in a tank manner, wherein the amount of running raw materials carried together in a tank manner is often very limited, so that the harvester cannot be applied for a longer time without interruption without other means. Furthermore, in the case of the use of a bucket, filling the tank of the harvester is very costly and may lead to environmental pollution. Alternatively, an additional dedicated vehicle with an operating material tank (Betriebsmittetlank) can be operated together, but this represents a significant logistic and financial effort.
Disclosure of Invention
The following tasks are proposed based on the aforementioned prior art: a travelable transport device for transporting at least one self-propelled harvester is further constructed, which avoids the drawbacks of the prior art and in particular simplifies the carrying of the necessary operating substances for the harvester.
This object is achieved by a mobile transport device.
Advantageous refinements are the subject matter of the preferred embodiments.
According to an exemplary embodiment of the present invention, a mobile transport device (in particular a transport trailer or transport vehicle) for transporting at least one self-propelled harvester is provided, having a loading surface and a loading platform which can be pivoted about a pivot axis and has an upper side and a lower side, the upper side being drivable by the harvester, wherein a volume-variable operating substance tank is arranged on the lower side of the loading platform, wherein, in order to feed the contents of the operating substance tank into the tank of the harvester without assistance, it is provided that the volume of the operating substance tank is reduced by loading during unloading (Abladen). For the unassisted supply, the operating substance tank on the underside of the loading dock is loaded on the one hand by the self-weight of the loading dock when the loading dock pivots about the pivot axis when the loading dock is resting with its free end on the ground. On the other hand, the volume of the operating material tank is further reduced when the harvester is driven over the loading dock in order to leave the transport device. The volume reduction of the operating substance tank caused by the compression itself contributes to: the liquid content contained in the operating substance tank, which is generally substantially incompressible, is pressed out of the operating substance tank. In order to change the loading platform from its transport position into a loading and unloading position in which the loading platform rests with its free end on the ground, manipulation of the loading platform can preferably be brought about by driving over the loading platform. Here, such a loading platform pivotable about a pivot axis operates like a teeter-totter (Wippe). The loading dock is displaced from the transport position into the loading and unloading position and vice versa in dependence on a mass displacement caused when the harvester to be transported is driven over the loading dock. Such pivoting (or tipping) about the pivot axis may be controlled by a spring damping system. In this way, abrupt loading of the operating substance tank is avoided, in order to avoid bursting of such a compressible operating substance tank.
The operating substance tank can in particular be made of an elastic, compressible material. Preferably, a rigid plate-like cover may be arranged on the underside of the operating substance tank. The cover is used for: the operating material storage bin is protected from damage when the dock, which is converted to the loading and unloading position, is passed by the harvester.
The operating substance tank may preferably be constructed as a telescopic bellows (Balg). The operating substance tank may in particular operate according to the type of bellows.
Furthermore, the transport device can have a frame which is embodied at least in sections as a hollow wall. Such a frame, which is embodied as a hollow wall in sections, forms a supply line for enabling the operating substance tank to be filled with operating substance. Such a segmented hollow wall frame may be in particular a part of the load surface.
In this case, a filling connection having a check valve can be arranged on such a hollow wall frame. By means of the check valve, it is avoided that: during unloading of the harvester, the operating substance tank may be able to flow out through the filler neck in the event of a reduced volume of the operating substance tank due to its own compression.
Furthermore, the operating substance tank can be connected to the section hollow wall frame in a fluid-conducting manner. Preferably, the operating substance tank can be connected directly to such a hollow wall frame in such a way that the operating substance tank is attached to such a hollow wall frame. Alternatively, the operating substance tank can be connected indirectly (for example by at least one elastic line section) to the hollow-walled frame. In this way, greater flexibility and operational safety in the event of repeated pivoting of the loading dock can be ensured.
According to a preferred development, a receptacle can be provided on the transport device for carrying a hose together, through which the operating substance tank can be connected to a tank connection of a tank on the harvester. The receptacle is preferably arranged below the load surface of the transport device. The hose is in particular accessible from one side of the transport device. The hose can be connected with its one end to the segmented hollow wall frame or directly to the operating substance tank.
Preferably, an attachment device receptacle is arranged detachably on the upper side of the loading dock, said attachment device receptacle being rotatable about a vertically oriented axis. The attachment mechanism receiving portion enables the attachment mechanism required for harvesting by the harvester to be carried simultaneously. The attachment mechanism receiving portion may include a swivel flange and a locking device. By means of the locking device, the attachment device (in particular the cutting mechanism) placed on the attachment device receptacle and the loading dock can be locked after occupying the transport position. Depending on the width of the attachment device, the attachment device can be placed on the attachment device receptacle transversely to the longitudinal axis of the transport device, as long as the attachment device does not protrude laterally beyond the load surface or beyond a frame surrounding the load surface. If the width of the attachment device to be transported exceeds the width of the transport device, the attachment device can be converted into a position parallel to the longitudinal axis of the transport device by means of the above-described attachment device receptacle rotatable about a vertically running axis and then locked in this position. By means of such a rotatable attachment means receptacle, the attachment means can be transported space-saving and together with the harvester without the need for further transport equipment (in particular further transport trailers). In this case, it is also advantageous if the loading surface of the towing vehicle to which the transport device is coupled can also be utilized in other ways. Instead of being used to receive the attachment instrument and/or the harvester, the loading surface of the towing vehicle may be used for additional transport of auxiliary material, harvesting or the like.
In particular, a wedge-shaped support element can be arranged on the free end of the loading dock, which wedge-shaped support element can be pivoted about an axis running transversely to the loading dock and can be detached. The support element can be used to pivot the loading dock and to unload the harvester without a change in volume of the running material tank on the underside of the loading dock occurring. For this purpose, the support element can space the operating substance tank vertically from the ground surface in such a way that the operating substance tank is not compressed together and thus changes its volume when driving over the loading dock.
Preferably, such a mobile transport device can be configured as at least two bridge transport trailers. For this purpose, the transport device can be embodied, for example, in a two-bridge configuration with a double bridge or a double bridge (Tandemachse).
In addition to this, the travelable transport device can be configured as a transport vehicle.
The transport device can in particular be designed to receive an attachment device and the self-propelled harvester, wherein the self-propelled harvester is positioned on the transport device essentially outside the operating substance tank. The self-propelled harvester and the associated attachment device can be transported simultaneously by means of the transport device, wherein the self-propelled harvester is positioned spaced apart from a running material tank arranged below the loading dock during transport. In this way, an overload of the spring damping system of the operating substance tank and of the loading dock is avoided.
Drawings
The invention is further elucidated below on the basis of embodiments shown in the drawings.
The drawings show:
fig. 1: a schematic view of the transport device in a loaded state;
fig. 2: a schematic view of the transport device according to fig. 1 when unloading the harvester;
fig. 3: a schematic view of a transport device according to another embodiment.
Detailed Description
Fig. 1 shows a transport device in a loaded state, which is implemented to transport a trailer 1. The transport device can also be configured as a transport vehicle. The transport trailer 1 is configured for transporting at least one self-propelled harvester 2 and an attachment 3. The transport trailer 1 comprises a loading surface 4 and a loading dock 5. The loading platform 5 can pivot about a pivot axis 6. The loading dock 5 has an upper side 7 that can be driven over by the harvester 2 and has an underside 8 that faces the ground. On the free end of the loading dock 5 that is supported on the ground in the loading (or unloading) position, a wedge-shaped support element 14 is arranged, which wedge-shaped support element 14 can be pivoted about an axis 15 running transversely to the loading dock 5 and can be removed.
Such a double-bridge transport trailer 1 is embodied as a front axle 9 and a rear axle 10, respectively, which are arranged below the load surface 4. For towing the transport trailer 1, a towing bar 11 is provided, by means of which towing bar 11 the transport trailer 1 can be coupled to a towing vehicle, such as a truck. The front axle 9 and the rear axle 10 are connected to each other by a steering link 12 for forcibly steering the rear axle 10.
For transporting the attachment means 3 and the harvester 2 simultaneously, it is provided that: as long as the working width of the attachment device 3 exceeds the width of the transport trailer 1 allowed in road traffic, the attachment device 3 is guided together in an orientation parallel to the longitudinal axis of the transport trailer 1. For this purpose, the attachment device receptacle 13 is detachably arranged on the upper side 7 of the loading dock 5. The attachment mechanism receiving portion 13 includes a swivel flange and a locking device. By means of the locking device, both the attachment device 3 placed on the attachment device receptacle 13 and the loading dock 5 can be locked after occupying the transport position.
On the underside 8 of the loading dock 5, a working substance tank 16 is arranged. The operating substance tank 16 is constructed of an elastic, compressible material. Thereby allowing the volume of the operating substance tank 16 to be varied. Preferably, a rigid plate-like cover 17 can be arranged on the underside of the operating substance tank 16 (i.e. on the side facing the ground). The cover 17 serves to protect the operating substance tank 16 from damage. The working substance tank 16 is preferably embodied as a telescopic bellows. The transport trailer 1 has a frame 18 which is embodied at least in sections as a hollow wall. The working substance tank 16 is connected in a fluid-conducting manner to such a segmented hollow wall frame 18. The frame 18 extends at least in sections in the longitudinal direction of the transport trailer 1 and forms part of the loading surface 4. On the side opposite the loading dock 5, the frame 18 may have a section 19 extending at least in sections in the vertical direction. To this end, the frame 18 may have a substantially L-shaped cross-section. A closable filling nozzle 20 is arranged at the free end of the section 19. Through this connecting piece 20, the frame 18 and the operating substance tank 16 connected thereto can be filled with operating substance. A non-return valve 21 is provided below the filling nipple 20.
Further, below the loading surface 4, a receiving portion 22 is provided for guiding the hose 23 together. The hose 23 is expandable for connection with a tank nipple of a tank on the harvester 2 located on the load surface 4. The length of the hose 23 is selected such that the hose 23 remains connected to the tank adapter during the movement of the harvester 2 out of its transport position towards the loading dock 5 and beyond the loading dock 5 during unloading.
For unloading, the attachment device 3 is pivoted from its transport position, in which the attachment device 3 is parallel to the longitudinal axis of the transport vehicle 1, into a receiving position, in which the attachment device 3 is oriented transversely to the longitudinal axis of the transport vehicle 1. The harvester 1 receives the attachment instrument 3 such that the attachment instrument receiving portion 13 can be at least partially removed. By at least partially removing the attachment device receptacle 13, the harvester 2 and the attachment device 3 located thereon can now be moved in the direction of the loading dock 5. The hose 23 was previously connected to a tank connection of the tank of the harvester 2.
As the pivot axis 6 of the dock 5 passes the harvester 2 during unloading, the dock 5 begins to tilt toward the ground. In order to prevent the loading dock 5 from sinking too quickly and thus causing damage to the running material tank 16 located below the loading dock 5, the pivoting (or tilting) about the pivot axis 6 is then monitored by means of a spring damping system arranged on the loading dock 5 and the load surface 4. While driving over the loading platform 5, the operating substance tank 16 is pressed against the ground and thereby reduces its volume. The operating substance contained in such a compressible operating substance tank 16 is pressed out by the pressure generated and is led unaided (i.e. without a conveyor) through a hose into the tank of the harvester 2. The non-return valve 21 prevents the run-on substances from escaping in the region of the filler neck 20.
Fig. 2 shows a schematic view of the transport trailer 1 according to fig. 1 when unloading the harvester 2. Here, wedge-shaped support elements 14 are used. The support element 14 rests on the ground and is secured by a locking portion 24, said locking portion 24 preventing the support element 14 from pivoting about an axis 15 running transversely to the loading dock 5. The locked support element 14 forms a rigid linear extension of the loading dock 5, so that the running material tank 16 is not pressed against the ground when the harvester 2 is driven over the loading dock 5.
Fig. 3 shows a schematic view of a transport trailer 1 according to another embodiment. Corresponding reference numerals are therefore reserved for the purpose of conforming the components of the transport vehicle 1. This is also an embodiment of a transport trailer 1 with two axles, instead of the double-axle embodiment according to fig. 1 and 2. Additionally, a height-adjustable support device 25 is arranged on the side of the transport trailer 1 opposite the loading dock 5. Furthermore, the working width of the attachment device 3 is smaller than the working width of the attachment device 3 shown in fig. 1. The working width of the attachment means 3 allows for co-transportation without being detached from the harvester 2.
The transport trailer 1 according to the invention is in particular designed to receive both the attachment means 3 and the self-propelled harvester 2, wherein the self-propelled harvester 2 is positioned on the transport trailer 1 essentially outside the operating substance tank 16. The self-propelled harvester 2 and the associated attachment 3 can be transported simultaneously by means of the transport trailer 1, wherein the positioning of the self-propelled harvester 2 is arranged spaced apart from the operating material storage bin 16 arranged below the loading dock 5 during transport. In this way, an overload of the spring damping system of the operating substance tank 16 and of the loading dock 5 is avoided.
