Description

Travelable transport device

Technical Field

The invention relates to a travelable transport apparatus according to the preamble of claim 1.

Background

For transporting the self-propelled harvesting machine, trucks can be used as the transportable transport device, which trucks have a load surface and a load platform, which is attached to the load surface or connected thereto when loading and unloading are required, wherein the load surface can be pivoted about a pivot axis.

Furthermore, transport trailers are used as a transportable transport device for transporting at least one mobile harvester, which are equipped with a loading surface and a loading platform (ramp), wherein the loading platform can be pivoted about a pivot axis and has an upper side and a lower side, the upper side being transportable by the harvester. These transport trailers are towed by a towing vehicle, such as a truck or the like.

Trucks for transporting harvesters are known, for example, from the document US 3,550,801 a.

A transport device embodied as a transport trailer according to the preamble of claim 1 is disclosed by document US4,607,996A. The transport trailer is designed for transporting an agricultural harvester, wherein the agricultural harvester is positioned on the transport vehicle transversely to the longitudinal axis of the transport vehicle. For this purpose, the pivotable loading platform is arranged laterally on a load surface which extends parallel to the longitudinal axis of the transport vehicle.

When transporting a mobile harvester over a long distance to areas with poor infrastructure by means of trucks or transport trailers, the problem may arise that the operating materials need to be carried along. The carrying-along of the operating material can take place in the manner of a tank, wherein the amount of operating material carried along in the manner of a tank is usually very limited, so that the harvester cannot be used for a longer time without interruption if no other means are used. Furthermore, in the case of the tank, filling the tank of the harvester is very costly and may lead to environmental pollution. Alternatively, additional special vehicles with an operating substance tank (betriebsmitetltank) can be operated together, but this represents a significant logistic and financial expenditure.

Disclosure of Invention

Based on the prior art, the following tasks are proposed: a mobile transport device for transporting at least one mobile harvester is further developed, which avoids the disadvantages of the prior art and in particular simplifies the carrying of the necessary operating material for the harvester.

This object is achieved by a travelable transport apparatus according to claim 1.

Advantageous developments are the subject matter of the dependent claims.

According to claim 1, a transportable transport device (in particular a transport trailer or transport vehicle) for transporting at least one mobile harvester is proposed, having a loading surface and a loading platform which is pivotable about a pivot axis and has an upper side which can be traversed by the harvester and a lower side, wherein a variable-volume operating material tank is arranged on the lower side of the loading platform, wherein for the purpose of supplying the contents of the operating material tank to the tank of the harvester without assistance, it is provided that the volume of the operating material tank is reduced by loading during the discharge (Abladen). For the power-free supply, the ballast tank on the underside of the loading platform is loaded on the one hand by the weight of the loading platform when the loading platform is pivoted about the pivot axis, when the loading platform rests with its free end on the ground. On the other hand, the volume of the working substance tank is further reduced when the harvester passes on the ramp in order to leave the transport device. The reduction in volume of the operating substance tank by its own compression contributes to: the liquid content, which is usually substantially incompressible, contained in the service substance tank is pressed out of the service substance tank. In order to transfer the ramp from its transport position into a loading and unloading position (in which the ramp rests with its free end on the ground), the handling of the ramp can preferably be brought about by driving over the ramp. Here, the platform, which can pivot about a pivot axis, operates like a see-saw (Wippe). The loading platform is displaced from the transport position into the loading and unloading position and vice versa as a function of the mass displacement caused when the harvester to be transported passes over the loading platform. This pivoting (or tipping) about the pivot axis can be controlled by a spring damping system. In this way, it is avoided that the service substance tank is suddenly loaded in order to avoid bursting of the compressible service substance tank.

The service 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 operational substance tank. The cover member is for: the tank of the operating substance is protected from damage when the loading platform converted into the loading and unloading position is driven by the harvester.

The service substance tank can preferably be designed in the form of a bellows (Balg). The service substance tank can in particular be operated in the manner of a 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-walled frame can be in particular a part of the load surface.

In this case, a filler neck with a non-return valve can be arranged on such a hollow-walled frame. By means of the non-return valve it is possible to avoid: during the discharge of the harvester, the operating material can flow out through the filler neck in the case of a volume reduction of the operating material tank due to its own compression.

Furthermore, the operating substance tank can be connected to the segmented hollow-walled frame in a fluid-conducting manner. Preferably, the service tank can be directly connected to such a hollow-walled frame in such a way that it is attached thereto. Alternatively, the service substance tank may be indirectly connected (for example via at least one elastic tube section) to the hollow-walled frame. In this way, greater flexibility and operational safety can be ensured during repeated pivoting of the ramp.

According to a preferred development, a receptacle can be provided on the transport device for carrying together a hose, by means of which the operating substance tank can be connected to a tank connection of a tank on the harvester. The receiving portion is preferably arranged below a load surface of the transport device. The hose is in particular accessible from one side of the transport device. In this case, the hose can be connected at one end to the segmented hollow-walled frame or directly to the operational material tank.

Preferably, an attached instrument receptacle is detachably arranged on the upper side of the ramp, said attached instrument receptacle being rotatable about a vertically running axis. The attached implement receiving portion enables the attached implements required for harvesting by the harvester to be carried simultaneously. The attachment instrument receptacle may include a rotating flange and a locking device. By means of the locking device, the attached instrument (in particular the cutting mechanism) placed on the attached instrument receptacle and the loading bay can be locked after taking up the transport position. Depending on the width of the attachment means, the attachment means can be placed on the attachment means receptacle transversely to the longitudinal axis of the transport device, as long as the attachment means does not project laterally beyond the load surface or beyond the frame surrounding the load surface. If the width of the attaching means to be transported exceeds the width of the transport device, the attaching means can be transferred into a parallel position relative to the longitudinal axis of the transport device by means of the above-mentioned attaching means receptacle which can be rotated about a vertically running axis and then locked in this position. By means of such a rotatable attachment receptacle, the attachment can be transported in a space-saving manner together with the harvester without additional transport equipment (in particular additional transport trailers). In this case, it is also advantageous if the load surface of the traction vehicle, to which the transport device is coupled, can also be used in other respects. Instead of being used to receive the attachment means and/or the harvesting machine, the load surface of the traction vehicle can be used for additional transport of auxiliary material, harvesting material or the like.

In particular, a wedge-shaped support element can be arranged at the free end of the ramp, which can be pivoted about an axis running transversely to the ramp and can be removed. The support element can be used to pivot the loading platform and to unload the harvester without a change in the volume of the tank running on the underside of the loading platform occurring in this case. For this purpose, the support element can space the tank from the ground in the vertical direction in such a way that it is not compressed together and thus changes its volume when it travels over the ramp.

Preferably, such a travelable transport apparatus can be configured as at least two bridge transport trailers. For this purpose, the transport device can be embodied in a two-bridge configuration, for example, with a double bridge or a double-bridge mounted (Tandemachse).

In addition to this, the travelable transport can be configured as a transport vehicle.

The transport device can in particular be designed to receive an attaching implement and the self-propelled harvesting machine, wherein the self-propelled harvesting machine is positioned on the transport device substantially outside the operating material 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 excessive loading of the spring damping system of the operating substance tank and of the loading dock is avoided.

Detailed Description

Fig. 1 shows a transport device embodied as a transport trailer 1 in a loaded state. The transport device may also be configured as a transport vehicle. The transport trailer 1 is designed for transporting at least one mobile harvester 2 and an attachment 3. The transport trailer 1 comprises a load surface 4 and a loading dock 5. The platform 5 can pivot about a pivot axis 6. The platform 5 has an upper side 7 that can be driven over by the harvester 2 and has a lower side 8 facing the ground. At that free end of the ramp 5 which 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 ramp 5 and can be removed.

This transport trailer 1 embodied as a double bridge comprises 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 tow bar 11 is provided, by means of which tow bar 11 the transport trailer 1 can be coupled to a towing vehicle (for example 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 the simultaneous transport of the attaching device 3 and the harvesting machine 2, provision is made for: as long as the working width of the attachment means 3 exceeds the width of the transport trailer 1 allowed in road traffic, the attachment means 3 is guided together in an orientation parallel to the longitudinal axis of the transport trailer 1. For this purpose, an attached instrument receptacle 13 is arranged detachably on the upper side 7 of the ramp 5. The attachment instrument receptacle 13 includes a rotating flange and a locking device. By means of the locking device, both the attachment means 3 placed on the attachment means reception 13 and the ramp 5 can be locked after taking up the transport position.

The transport trailer 1 has a frame 18 which is embodied at least in sections as a hollow wall, the transport trailer 16 being connected to the frame 18 in a fluid-conducting manner, the frame 18 extending at least in sections in the longitudinal direction of the transport trailer 1 and forming part of the loading surface 4, the frame 18 having a section 19 which extends at least in sections in the vertical direction, the frame 18 having a substantially L-shaped cross section, on the side opposite the loading ramp 5, a filler neck 20 which can be closed at the free end of the section 19 being provided, the transport trailer 16 being composed of a resilient, compressible material, whereby the volume of the transport trailer 16 can be varied, preferably a rigid plate-like cover 17 being arranged on the underside of the transport trailer 16 (i.e. on the side facing the ground), the cover 17 serving to protect the transport trailer 16 from damage, the transport trailer 16 being preferably embodied as a telescopic bellows, the frame 18 having at least in sections a hollow wall being connected to the frame 18 in a fluid-conducting manner, the frame 18 having a section 19 which extends at least in sections in the vertical direction, the frame 18 having a substantially L-shaped cross section, a filler neck 20 being arranged at the free end of the section 19, and a filler neck 20 being connectable to the transport trailer 16, and a non-return valve being arranged below.

Furthermore, a receiving section 22 is provided below the load surface 4 for the purpose of guiding a hose 23 together. The hose 23 can be deployed for connection to a tank connection of a tank on the harvester 2 on the load surface 4. The length of the hose 23 is selected such that the hose 23 remains connected to the tank connection during the movement of the harvester 2 out of its transport position in the direction of the loading platform 5 and beyond the loading platform 5 during unloading.

For unloading, the attaching means 3 is pivoted from its transport position, in which the attaching means 3 is parallel to the longitudinal axis of the transport vehicle 1, into a receiving position, in which the attaching means 3 is oriented transversely to the longitudinal axis of the transport vehicle 1. The harvester 1 receives the attachment means 3 such that the attachment means receiving portion 13 can be at least partially removed. By removing the attachment means receptacle 13 at least partially, the harvester 2 and the attachment means 3 located thereon can now be moved in the direction of the loading dock 5. The hose 23 is connected to a tank connection of the tank of the harvester 2.

As the pivot axis 6 of the platform 5 passes the harvester 2 during unloading, the platform 5 begins to tilt towards the ground. In order to prevent the loading platform 5 from sinking too quickly and thus causing damage to the travelling material tank 16 located below the loading platform 5, the pivoting (or tipping) about the pivoting axis 6 is monitored by means of a spring damping system arranged on the loading platform 5 and the load surface 4. When driving over the ramp 5, the tank 16 is pressed against the ground and thus reduces its volume. The operating substance contained in such a compressible operating substance tank 16 is pressed out by the pressure generated and is conveyed without assistance (i.e. without conveying means) through a hose into the tank of the harvester 2. The non-return valve 21 prevents the operating substance 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, a wedge-shaped support element 14 is used. The support element 14 rests on the ground and is secured by the locking portion 24, said locking portion 24 preventing the support element 14 from pivoting about the axis 15 running transversely to the ramp 5. The locked support elements 14 form a rigid linear extension of the platform 5, so that the tank 16 of mobile material is not pressed against the ground when the harvester 2 is driven over the platform 5.

Fig. 3 shows a schematic view of a transport trailer 1 according to another embodiment. Corresponding reference numerals have been retained in order to make the components of the transport vehicle 1 identical. This is also the case for a transport trailer 1 with two axles, using the embodiment with a double-axle installed side by side, instead of the embodiment with a double-axle according to fig. 1 and 2. In addition, a height-adjustable support device 25 is arranged on the side of the transport trailer 1 opposite the loading bay 5. Furthermore, the working width of the attaching means 3 is smaller than the working width of the attaching means 3 shown in fig. 1. The working width of the attachment means 3 allows for co-transport without being detached from the harvester 2.

The transport trailer 1 according to the invention is designed in particular for simultaneously receiving the attachment 3 and the self-propelled harvester 2, wherein the self-propelled harvester 2 is positioned on the transport trailer 1 substantially outside the operating material 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 provided during transport at a distance from a running material tank 16 arranged below the loading dock 5. In this way, an excessive loading of the spring damping system of the operating substance tank 16 and the loading ramp 5 is avoided.
