Combination transfer wagon (1) for bulk goods of all kinds, in particular for agricultural products such as grain, potatoes, beets, and much more, characterized in that the vehicle frame (2) has a height offset (Hv) such that a front body area (Av) is lower by the height offset (Hv) and a rear body area (Ah) is thus created that is higher. Further characteristic of claim 1 is that the front body area (Av) is used for various conveying devices adapted to the types of goods to be transported, such as a grain trough with auger conveyor (4), a potato unloading belt with post-cleaning (5), a beet unloading belt (6), or other unloading devices, and all of these elements can be easily and alternately connected to the rear body area (Ah) via two suspension points (E1) and (E2) and two further fixing devices (F1) and (F2).According to the invention, in the rear body area (Ah), the majority of the transport volume is accommodated in a tipping trough (3), which can then, by tipping towards the front body area (Av), unload the transported goods into the conveyor devices such as a grain trough with auger conveyor (4), a potato unloading belt with post-cleaning device (5), a beet unloading belt (6) or other unloading devices. According to the invention, the vehicle frame (2) and the tipping trough (3) mounted around the tipping axis (KA), together with a drawbar (7) and a chassis (8), form a basic unit, a transfer wagon (9), to which a wide variety of unloading devices can be mounted and operated between the drawbar (7) and the rear body area (Ah).

Description

[0001] The invention relates to a new form of transfer wagon for bulk goods of all kinds, in particular for agricultural products such as potatoes, beets or grain.

[0002] In practice, so-called transfer wagons are often used today to increase the productivity of harvesting machines. The most common of these are transfer wagons for grain, which are used between the combine harvester and the road transport vehicle. These are equipped with auger conveyors for unloading or transferring the grain to the transport vehicle. However, auger conveyors are not suitable for tuber-shaped crops such as potatoes, onions, and beets, so transfer wagon concepts with suitable conveyor belts have been developed for these crops.

[0003] The systems are available in a wide variety of designs, but are always designed for a specific purpose, which means they have relatively short deployment times and therefore also cause relatively high costs.

[0004] The aim of the invention is to enable the combination transfer wagon according to the invention to be used for all crop types. This is achieved by allowing various unloading devices to be alternately suspended and operated on a basic transfer wagon unit, between a rear body space with a tipping trough and the drawbar as the connecting element to the tractor. A novel feature is that the unloading devices are located, as described, close to the tractor behind the drawbar, thus providing excellent visibility for the driver, which is very important when approaching transport vehicles.

[0005] According to the invention, the conveying elements are designed in such a way that they are grain-tight and trickle-tight for granular goods such as grain, particularly gentle for tuberous fruits such as potatoes and onions, and very robust for sugar beets, for example.

[0006] The offset vehicle frame according to the invention also represents a major advantage, since the height offset and the resulting two body spaces enable easy transfer of the transported goods into the unloading devices by simply tilting the rear tipping trough.

[0007] The drive train running through the center of the vehicle frame with the subsequent offset gearbox enables the unloading equipment to be driven from the basic unit, the transfer wagon. This is advantageous for the arrangement of the gearboxes, pumps, etc. to be driven and the connection situation to the tractor always remains the same.

[0008] The invention extends not only to the features of the individual claims, but also to their combination.

[0009] The invention is illustrated by an embodiment based on the Fig. 1 to 16 and is described in more detail below.

[0010] It shows: Fig. 1 shows a schematic representation of the combination transfer wagon with three exemplary unloading devices Fig. 2 shows a schematic representation of the basic unit transfer wagon in perspective from the front Fig. 3 shows a schematic representation of the vehicle frame Fig. 4 shows schematically the representation of the vehicle frame in perspective from the front Fig. 5 shows a schematic representation of the tipping trough Fig. 6 shows a schematic representation of the hanging of a discharge device Fig. 7 shows a schematic representation of the drive train Fig. 8 shows a schematic representation of the drive train with outlet to the grain trough Fig. 9 shows a schematic representation of the combination transfer wagon with grain trough Fig. 10 shows a schematic representation of the combination transfer wagon with grain trough in plan view with section indication Fig. 11 shows schematically the representation of section AA from Fig. 8 Fig. 12 shows a schematic representation of the combination transfer wagon with tilted tipping trough Fig. 13 shows a schematic representation of the combination transfer wagon and a potato unloading belt with post-cleaning Fig. 14 shows a schematic representation of the combination transfer wagon and a potato unloading belt with post-cleaning in section Fig. 15 shows a schematic representation of the combination transfer wagon with a beet unloading belt Fig. 16 shows a schematic representation of the basic unit transfer wagon with wheel axles

[0011] Fig. 1 shows a schematic representation of the combination transfer wagon (1) with three exemplary possible unloading devices, the grain trough with conveyor screw (4), the potato unloading belt with post-cleaning (5) and the beet unloading belt (6), which can be attached to the basic unit transfer wagon (9), which illustrates the diverse possible uses of the combination transfer wagon (1) according to the invention.

[0012] Fig. 2 shows a schematic representation of the basic unit, the transfer wagon (9), in perspective from the front, and thus shows the basic structure of the vehicle frame (2), a chassis (8), here an example of a belt drive, the drive train (10) and the tipping trough (3), which is mounted on the vehicle frame (2) so as to be rotatable about the tipping axis (KA).

[0013] Fig. Figure 3 shows a schematic representation of the vehicle frame (2), the essential criterion of which, according to claim 1, is the height offset (Hv) between the tilt axis (KA) and the upper edge of the vehicle frame (2) in the front body area (Av). Also visible is the rear body area (Ah), which adjoins the front body area (Av) at the tilt axis (KA).

[0014] Fig. 4 shows a schematic representation of the vehicle frame (2) in perspective from the front, showing the two side walls of the vehicle frame (2), the side wall Ik (11) and the side wall re (12). The side walls can be a welded construction that is an integral part of the vehicle frame (2), but can also be attached with a screw connection. According to claim 1, the side wall Ik (11) and the side wall re (12) contain the suspension points re and Ik (E1 and E2), the fixing devices re and Ik (F1 and F2), as well as the tilting axle bearing re (KAL re) and the tilting axle bearing Ik (KAL Ik). In the simplest case, the fixing devices (F1 and F2) can also be a screw connection.

[0015] Fig. 5 shows a schematic representation of the tipping trough (3) with its tipping axis (KA) and the sealing strips Ik (13) as well as the sealing strip re (14), which seals the tipping trough (3) against the side walls of the vehicle frame during assembly.

[0016] Fig. 6 shows a schematic representation of the hanging of an unloading device, here as an example the beet unloading belt (6), which is first hooked onto the hooking points re and Ik (E1 and E2) of the basic unit transfer wagon (9) with the hooks 1 and 2 (H1 and H2) attached on both sides and is additionally secured against unintentional unhooking with the fixing devices re and Ik, here only visible on the left (F2).

[0017] Fig. Figure 7 shows a schematic representation of the drive train with offset gearing (10), which in practice will be constructed in several parts, but according to the invention extends through the drawbar (7) and the vehicle frame (2) to behind the height offset (Hv) and, after an offset gearing, has at least one drive train exit to the front (10a). This design has the advantage that the drive of the various unloading devices can be designed more flexibly, as it requires more installation space.

[0018] Fig. 8 shows a schematic representation of the drive train with the front output (10 a) via a cardan shaft (16) to the gearbox of the grain trough auger (17) of the grain trough unloading device with auger conveyor (4), which is constructed here as an example on the basic unit transfer wagon (9).

[0019] Fig. Figure 9 shows a schematic representation of the combination transfer wagon (1) with a grain trough with auger conveyor (4) mounted on the transfer wagon base unit (9) and a splash guard (4a) which is provided to prevent grain loss when transferring combine harvesters and represents only one possible option. The illustration further illustrates the advantage that, thanks to the inventive design, the unloading devices, here, for example, the grain trough with auger conveyor (4), are directly in the field of vision of the tractor driver.

[0020] Fig. 10 shows a schematic representation of the combination transfer wagon (1) and the grain trough with conveyor screw (4) in plan view with section information for the following Fig. 11. Also visible is the rear body area (Ah), which connects to the front body area (Av) at the tilting axis (KA).

[0021] Fig. 11 shows schematically the representation of section AA from Fig. 8 and thus the principle of the design of the vehicle frame (2), on which the tipping trough (3) with the horizontal and flat floor tipping trough (BK) can hold the majority of the respective transported goods and can then be fed to the conveyor screw grain trough (FS) via a hopper grain trough (TT) after the tipping axis (KA), as shown here.

[0022] Fig. Figure 12 shows a schematic representation of the combination transfer wagon (1) with a tilted tipping trough (3) for complete emptying. According to claim 4, the tipping trough (3) can also be replaced by a structure with a rolling or scraper floor or a pusher system. All of these systems are state of the art and are therefore not described in detail. However, for bulk materials, the tipping trough (3) is a cost-effective option and can also be more easily designed to be grain-tight.

[0023] Fig. 13 shows a schematic representation of the combination transfer wagon (1) and a potato unloading belt with post-cleaning (5) mounted on the basic unit transfer wagon (9).

[0024] Fig. Figure 14 shows a schematic cross-sectional view of the combination transfer wagon (1) and a potato unloading belt with post-cleaning system (5), which further illustrates the advantage of the height offset (Hv), as it makes it possible to convey the transported goods, such as potatoes, according to the potato flow (KF) shown, first via a cross belt (18) to one side, to a feed belt (19), which then transfers the potatoes to a roller cleaner (20). From there, the potatoes are transferred to a corresponding unloading belt (21).

[0025] Fig. Figure 15 shows a schematic representation of the combination transfer wagon (1) with a beet unloading belt (6) mounted on the transfer wagon base unit (9). The illustration also shows that the unloading devices can be positioned to the left or right in the unloading direction, depending on which harvesting machines are to be served with the combination transfer wagon (1).

[0026] Fig.Figure 16 shows a schematic representation of the basic unit, the transfer wagon (9) with a wheel axle (15) and a second wheel axle (15a), as shown. In principle, single- or multi-axle chassis or belt-type running gear can be used, depending on the total weight.
