Description

[0001] The invention relates to a transfer device for an agricultural harvesting machine. Furthermore, the invention relates to an agricultural harvesting machine.

[0002] DE 10 2007 037 710 A1 discloses an agricultural harvesting machine designed as a forage harvester with an unloading device. The unloading device is pivotally attached to the agricultural harvesting machine at a first end or section via a pivot point. At an opposite second end or section, the unloading device has a discharge flap. The unloading device has two segments that are connected to each other in an overlapping area. The segments have a U-shaped base body with guide surfaces that serve to receive a closing plate.

[0003] DE 10 2014 115 503 A1 discloses another agricultural harvesting machine with a transfer device.

[0004] Based on this, the present invention aims to create a novel loading device for an agricultural harvesting machine which, while being lightweight, can optimally absorb the forces and moments acting on it during operation.

[0005] This task is solved by an overloading device of an agricultural harvesting machine according to claim 1.

[0006] According to the invention, the supporting structure has profile tubes on a bottom side and angle rails on a top side, wherein the profile tubes and the angle rails are connected at or adjacent to the first end or first section via further profile tubes, and wherein the profile tubes and the angle rails are connected at a second end or second section opposite the first end or first section via a box profile.

[0007] The overloading device according to the invention allows for the optimal absorption of forces and moments acting on it during operation, while maintaining a low weight.

[0008] Preferably, the profile tubes running along the underside form a compressive load-bearing structure, and the angle rails running along the top side form a tensile load-bearing structure. This ensures optimal absorption of forces and moments acting on the loading device during operation, while maintaining low weight.

[0009] Preferably, the profile tubes running along the underside and / or the other profile tubes are square tubes. Square tubes are particularly preferred to optimally absorb forces and moments acting during operation while maintaining low weight.

[0010] Preferably, the box section has a flange designed for connecting a discharge spout extension and / or a discharge spout joint and / or a discharge flap, wherein the box section has bottom walls extending between the profile tubes on its underside and side walls extending between each angle bracket and a profile tube, and wherein the flange is welded to each of the profile tubes, each of the angle brackets, and each of the side walls. This allows for optimal connection of a discharge spout extension and / or a discharge spout joint and / or a discharge flap to the supporting structure of the unloading device according to the invention, thereby enabling optimal absorption of forces and moments acting on the supporting structure from these assemblies.

[0011] Preferred embodiments of the invention are described in the dependent claims and the following description. Exemplary embodiments of the invention are explained in more detail with reference to the drawing, without being limited thereto. The drawing shows: Fig. 1 a first perspective view of an overloading device according to the invention; Fig. 2 a second perspective view of the overloading device according to the invention; Fig. 3 a section of the overloading device according to the invention in the area of ​​a box profile thereof; Fig. 4 the cross-section IV-IV of the Fig. 3.

[0012] Fig. 1 and Fig. Figure 2 shows different perspective views of an unloading device 1 according to the invention for an agricultural harvesting machine. An unloading device 1 is also referred to as a discharge spout.

[0013] The transfer device 1 has a support structure 2 which is pivotably attached to an agricultural harvesting machine at a first end or a first section 2a. Fig. 1, Fig. Figure 2 shows a pivot joint 3 in the area of ​​the end 2a, about which the loading device 1 attached to the agricultural harvesting machine can be pivoted or tilted relative to the agricultural harvesting machine via the support structure 2.

[0014] In the state of the unloading device 1 attached to the agricultural harvesting machine, the support structure 2 has profile tubes 4 on a lower surface 2b and angle brackets 5 on a higher surface 2c. Thus, on the lower surface 2b, two profile tubes 4b extend from the first end or first section 2a towards an opposite second end or an opposite second section 2b of the support structure, preferably from the pivot joint 3. Along the higher surface 2c, two angle brackets 5 extend from the first end or first section 2a towards the opposite second end or the opposite second section 2d. Both the profile tubes 4 and the angle brackets 5 have a curved contour extending from the first end or first section 2a towards the second end or the second section 2d.

[0015] At or adjacent to the first end or first section 2a, the profile tubes 4 are connected to the angle brackets 5 via further profile tubes 6. These further profile tubes 6 extend from the pivot joint 3 towards the angle brackets 5, namely at the first end or first section 2a of the supporting structure 2.

[0016] At the first end or first section 2a, on each side of the supporting structure 2, between each of the profile tubes 4 and each of the angle rails 5, there extends another profile tube 6.

[0017] At the second end or second section 2d opposite the first end or first section 2a, the supporting structure 1 has a box profile 7, via which the profile tubes 4 and the angle rails 5 are connected to each other at the second end or second section 2d.

[0018] The supporting structure 2 of the overloading device 1 according to the invention therefore has the profile tubes 4 and the angle rails 5, which extend curved from the first end or first section 2a towards the second end or second section 2d, wherein in the area of ​​the first end or first section 2a a profile tube 4 is connected to an angle rail 5 via a further profile tube 6, and wherein in the area of ​​the second end or second section 2d the box profile 7 is present, which connects the profile tubes 4 and the angle profiles 5.

[0019] The box profile 7 has a flange 8, wherein the flange 8 is preferably designed or configured to attach a discharge manifold extension (not shown), a discharge manifold joint (not shown), or a discharge flap to the support structure 2.

[0020] A discharge spout extension preferably has a support structure analogous to that of the unloading device. Profile tubes are provided on the underside to absorb compressive loads, and angle brackets are provided on the upper side to absorb tensile loads. The profile tubes and angle brackets of a discharge spout extension are connected at both ends by a box section. This box section preferably corresponds substantially to that of the unloading device and has a flange on each of its two ends, allowing it to be connected to an unloading device, a discharge spout joint, another discharge spout extension, and / or a discharge flap.

[0021] The profile tubes 4 running along the underside 2b of the support structure 2 form a compressive load string, and the angle rails 5 running along the top side 2c form a tensile load string of the support structure 2, in order to optimally absorb the forces and moments acting on the unloading device 1 and thus on the support structure 2 during operation. As already described, the angle rails 5 and the profile tubes 4 are connected via the further profile tubes 6 in the area of ​​the first end or first section 2a, where the unloading device 1 or support structure 2 is attached to the agricultural harvesting machine. This couples the tension string and the compression string to each other in the area of ​​the first end or first section 2a. At the opposite second end or opposite second section 2d, this coupling of the tension string and the compression string is achieved via the box section 7.

[0022] The box profile 7 has two bottom walls 9, 10 extending between the profile tubes 4 on its underside. The two bottom walls 9, 10 run parallel to each other, and when the transfer device 1 is attached to the agricultural harvesting machine, the lower bottom wall 10 is directly attached to both profile tubes 4.

[0023] In the area of ​​the box profile 7, two side walls 11, 12 extend between each angle rail 5 and the profile tube 4 arranged on the same side. Both side walls 11, 12 engage according to Fig. 4 both at the respective angle rail 5 and at the respective profile tube 4. The upper bottom wall 9 engages the inner side walls 11.

[0024] The flange 8 is firmly connected by welding to each of the profile tubes 4 as well as to each angle bracket 5. Furthermore, all side walls 11, 12 of the box section 7 are welded to the flange 8. Additional welded connections are preferably formed between the flange 8 and the bottom walls 9, 10.

[0025] The profile tubes 4 and the further profile tubes 6 are preferably square tubes.

[0026] Between the box profile 7 formed at the second end or second section 2d and the first end or first section 2a of the supporting structure 2, the loading device 1 has a single bottom wall 13 extending between the profile tubes 4 on its underside 2b. Furthermore, in this section, between section 2a and section 2b, there is a single side wall 14 on each side.

[0027] The bottom wall 13 transitions into the upper bottom wall 9 of the box profile 7, the side walls 14 transition into the inner side walls 11 of the box profile 7.

[0028] A sealing plate (not shown) is attached to the top of the angle rails 5. During operation, the crop being transferred by the transfer device moves along this sealing plate.

[0029] What is the best way? Fig. The support structure 2, which can be removed from section 4, has a receptacle 15 for a preferably hydraulic actuating cylinder or piston connected to it in the area of ​​the underside 2b. This receptacle 15 extends between the two profile tubes 4 and is preferably connected to them by welding. In a central section, the receptacle 15 has a connection section 16 for the actuating cylinder or piston. The support structure 2, and thus the loading device 1, can be pivoted or tilted via the rotary joint 3 by means of the actuating cylinder or piston.

[0030] What is the best way? Fig.In the area of ​​the first end or first section 2a of the transfer device 1, support bodies 17 are provided, which connect to the side walls 14 on the outside. Each of the two support bodies 17 is connected on one side to the respective profile tube 4 and on the other side to the respective further profile tube 6 and preferably also to the respective side wall 14 by welding.

[0031] Because the flange 8 is welded to these assemblies in the area of ​​the two profile tubes 4, the two angle brackets 5, the four side walls 11, 12, and preferably also both bottom walls 9, 10 of the box section 7, each individual weld seam is subjected to a significantly lower load. This increases the reliability of the connection of the flange 8.

[0032] The invention further relates to an agricultural harvesting machine with a transfer device 1 according to the invention. The agricultural harvesting machine is preferably a forage harvester.

[0033] The overloading device 1 has a low weight and can optimally absorb forces and moments acting upon it during operation.
