Description

[0001] Agricultural machine for applying spray liquid and / or granular material to a field

[0002] The invention relates to an agricultural machine for applying spray liquid and / or granular material to a field and a height adjustment for a boom of an agricultural machine.

[0003] Agricultural machines for applying spray liquid and / or granular material have a container in which spray liquid and / or granular material is transported from the farm to the field for application.

[0004] Since these containers have a capacity of several hundred liters or more, and the farmer needs to be able to fill them, take samples, extract material, or dispense substances such as liquids through an access opening, these agricultural machines are equipped with a raised platform. This allows, for example, a view into the container from above. The platform is accessible via a ladder.

[0005] Against this background, the object of the present invention is to provide an agricultural machine for applying spray liquid and / or granular material to a field, or a sub-assembly of the agricultural machine for applying spray liquid and / or granular material to a field, which can be manufactured cost-effectively and with minimal material usage, and which, as an alternative to known designs, ensures safe access to a platform of the machine.

[0006] This problem is solved by the features of the independent patent claims. Further advantageous developments are the subject of the dependent claims.

[0007] A first aspect of the present invention comprises an agricultural machine for applying spray liquid and / or granular material to a field. This could be, for example, a field sprayer or a fertilizer spreader.

[0008] The agricultural machine has a frame that supports a platform and / or a container and / or a height adjustment mechanism for a boom. The height adjustment mechanism allows, for example, the boom to be adjusted in height relative to the machine's frame.

[0009] Furthermore, the agricultural machine includes a linkage, such as a spray boom, for arranging application devices, such as spray nozzles or outlets or pneumatic outlets.

[0010] Furthermore, the agricultural machine includes a height adjustment for the linkage, which connects the linkage to the frame and / or is attached to both the linkage and the frame.

[0011] The height adjustment mechanism has a first and a second adjustment device for height guidance and / or height adjustment of the linkage relative to the frame.

[0012] Furthermore, the agricultural machine includes an area for boarding and / or for a person to stand on and remain on the machine, and / or for accessing a platform. This area is laterally bounded by the first and second adjustment mechanisms and / or the frame, and / or partially enclosed by the first and second adjustment mechanisms and / or the frame. Thus, the agricultural machine provides an area at its rear, or at the height adjustment mechanism of a boom, from which a rear-mounted platform or work platform, such as a crop sprayer or a self-propelled machine, can be accessed. This represents an optimal solution regarding the space required for boarding the agricultural machine, e.g., from the rear.

[0013] Furthermore, the first and second adjustment devices can be spaced apart from each other, for example, perpendicular to the direction of travel of the agricultural machine. This increases stability.

[0014] The area between the first and second adjustment mechanisms can be positioned and / or arranged to provide a space where a person can stand and / or access a platform of the agricultural machine. This allows for an optimal location on the agricultural machine for access. Furthermore, the first and / or second adjustment mechanism can each form a four-bar linkage and / or a parallelogram linkage. This ensures, for example, that the linkage remains unchanged in its spatial orientation, even when the height is adjusted.

[0015] Each adjusting device can have a first link, which may be attached to the frame. Furthermore, each adjusting device can have a second link, which may be attached to a support frame for the linkage.

[0016] Furthermore, each adjusting device can have a third and fourth link, each of which can connect the first link to the second link. The third link can be pivotally connected to the first and second links. Likewise, the third and fourth links can be pivotally connected to the first and second links.

[0017] Furthermore, the first, second, third and / or fourth element can be formed by a profile.

[0018] Furthermore, the first and / or second adjustment mechanism can each include a lifting mast or lifting device. The lifting mast or lifting device can have a length-adjustable sliding guide, similar to that of a forklift truck, which allows the distance of the linkage to the ground to be changed.

[0019] Furthermore, the agricultural machine may be designed to have a ramp to overcome a height difference and / or to access or climb onto a platform of the agricultural machine. The ramp may be located within this area.

[0020] Furthermore, the area or ascent may include a ladder, a folding ladder, a sliding ladder, a step ladder or a hook ladder.

[0021] Furthermore, the ascent can be designed as a ladder, a folding ladder, a sliding ladder, a step ladder or a hook ladder.

[0022] Each of the aforementioned forms of a ladder can be arranged on the agricultural machine or on the frame of the agricultural machine, or be removable and / or attachable to the frame or a platform of the agricultural machine.

[0023] Furthermore, the platform or access area of ​​the agricultural machine may have at least one step for a person's foot. The platform or access area of ​​the agricultural machine may also have rungs for climbing up and down, which may be fitted into two stiles on the left and right. Alternatively, the platform or access area of ​​the agricultural machine may have two stiles, which may be telescopic, sliding, foldable, and / or extendable. The stiles may be attached to the agricultural machine or its frame, or they may be removable and / or attachable to the frame or platform of the agricultural machine.

[0024] Furthermore, the access ramp of the agricultural machine can be designed to be telescopic, relatively movable relative to the frame, foldable or extendable.

[0025] Furthermore, the area for boarding the agricultural machine and / or for a person to board and remain on it and / or for accessing a platform of the agricultural machine may be bounded by at least six theoretical faces and / or have a hexahedron shape. The area may have a volume that allows a person to remain on it and / or to board a work platform of the agricultural machine. The area or volume may be chosen such that exceptionally tall and / or wide individuals can board the agricultural machine without injury.

[0026] A first theoretical side surface can be formed by the frame, or by a part of the frame, or by the agricultural machine.

[0027] The height adjustment mechanism can have a support frame to which the linkage can be connected. A second theoretical side surface can be formed by the support frame and / or by the linkage, or by a part of the linkage.

[0028] The support frame can form a second element of each adjustment device and connect the two adjustment devices, e.g., transversely to the direction of travel.

[0029] The first and second side surfaces can be arranged opposite each other.

[0030] A third and fourth side surface can each be formed by at least one or two connections, or by at least one or two links of the two adjusting devices, which can movably connect the first side surface, the frame, or the agricultural machine to the support frame. The third and fourth side surfaces can be arranged opposite each other.

[0031] A fifth side surface can be formed by the ground on which the agricultural machine stands.

[0032] A sixth side surface can be oriented in the same direction as the ground and can be spaced away from the ground. The sixth side surface can be spaced at least 5 meters away from the ground.

[0033] Furthermore, the agricultural machine may have a platform or work platform leading to an access opening of a container on the agricultural machine. The platform can serve as elevated access for a person to the access opening of the container on the agricultural machine. Additionally, the platform and the access opening of the container on the agricultural machine may be positioned so that the access opening is within arm's reach of a person. This allows a person to open and / or close the access opening from the platform.

[0034] Furthermore, the agricultural machine may have a container with an access opening for servicing the agricultural machine and / or for filling the container of the agricultural machine, e.g. with liquid, and / or for removal, such as taking samples, material or distribution material, e.g. of liquid.

[0035] Furthermore, it is possible that the height adjustment has at least one actuating device for moving the first and / or second adjustment device and / or for moving a second element of the first and / or second adjustment device.

[0036] The at least one adjusting device can achieve a relative height adjustment of the linkage relative to the frame of the agricultural machine.

[0037] The at least one adjusting device can be rotatably arranged on the frame on one side and on the first and / or second adjusting device on the other.

[0038] Furthermore, the at least one adjusting device can be rotatably arranged on the frame and on the first and / or second adjusting device such that, along a first direction in which the at least one adjusting device can be extended, the distance of the second element of the first and / or second adjusting device to the ground increases. Alternatively or additionally, the at least one adjusting device can be rotatably arranged on the frame and on the first and / or second adjusting device such that, along a second direction opposite to the first, the at least one adjusting device can be shortened, thereby shortening the distance of the second element of the first and / or second adjusting device to the ground.

[0039] Furthermore, the agricultural machine may be provided with at least one operating mode in which the linkage and / or the adjustment mechanism can be moved and / or positioned in a way that is suitable for a person to stand on and / or climb onto, particularly in a selectable manner and / or by means of the at least one or another adjusting device. The position is preferably designed such that a person can stand on the platform and / or use the access mechanism with particular comfort. In particular, it may be provided that the linkage and / or the one or more adjusting devices are positioned as high as possible, especially higher than in the working and / or transport position.

[0040] A second aspect of the present invention comprises a height adjustment for a linkage of an agricultural machine.

[0041] It is expressly pointed out that the features of the agricultural machine, as mentioned under the first aspect, can be used individually or in combination for height adjustment.

[0042] In other words, the features relating to the agricultural machine mentioned above under the first aspect of the invention can also be combined with further features under the second aspect of the invention. Conversely, features of the agricultural machine can also be combined with further features of the height adjustment mechanism for a linkage of an agricultural machine.

[0043] A height adjustment mechanism for the boom of an agricultural machine comprises a first and a second adjustment device for guiding the boom. Using this height adjustment mechanism, the height of the boom relative to the machine's frame can be changed. Each adjustment device has a first link that can be attached to the frame of the agricultural machine. Furthermore, each adjustment device has a second link that can be attached to a support frame of the boom.

[0044] In addition, each adjusting device has a third and / or fourth link, which is connected to the first link and to the second link, e.g. by a hinge.

[0045] Furthermore, the two adjustment devices and / or their third and / or fourth links are designed and / or spatially aligned and / or spaced apart from each other in such a way that an area for climbing onto an agricultural machine and / or for a person to climb onto and remain on, and / or for climbing onto a platform of an agricultural machine, or for accessing an agricultural machine, is or can be placed in a space between the two adjustment devices or between the first and second links as well as between the third and / or fourth links, in order to allow a person to climb onto a platform of an agricultural machine. Thus, an agricultural machine can have an area at its rear or at its height adjustment mechanism for a linkage, on which a platform or work platform of the agricultural machine, such as a rear-mounted platform, can be attached.This provides an optimal solution regarding the space required for accessing the agricultural machine, e.g., from the rear, such as a crop sprayer or a self-propelled machine.

[0046] Furthermore, the first and / or second adjustment mechanism can each form a parallelogram linkage. The first and second links and / or the third and fourth links can also be aligned parallel to each other.

[0047] Furthermore, it is conceivable that the first, second, third and / or fourth element is formed by a profile.

[0048] Furthermore, it is possible that the first and / or second adjustment mechanism each include a lifting mast or lifting device. The lifting mast or lifting device may have a length-adjustable sliding guide, similar to that of a forklift truck, which allows the distance of a support frame of an agricultural machine's linkage to the ground to be changed. Additionally, the height adjustment mechanism may include a support frame for an agricultural machine's linkage, via which the first adjustment mechanism is connected to the second adjustment mechanism. The support frame may form the second link for each adjustment mechanism or be formed by the fourth links of both adjustment mechanisms.

[0049] Furthermore, the two adjustment devices or their third and / or fourth links can be spaced apart from each other and attached to the support frame and / or shaped in such a way that a person can move in a room or area spanned by the first, second and third and / or fourth links.

[0050] Furthermore, the two adjusting devices or their third and / or fourth links can be spaced apart from each other and attached and / or shaped on the support frame in such a way that a person is able to climb on and remain between the first and second links and between the third and / or fourth links, e.g. by using a ladder on an agricultural machine.

[0051] The inventive concept presented above is expressed again and in addition in other words below.

[0052] This idea can – to put it simply – refer to the rear of a crop protection sprayer (self-propelled or towed) or other agricultural machinery, on which a parallelogram linkage for boom guidance may be installed.

[0053] The rear of crop protection sprayers can be equipped with a walk-on platform for one person and offer space for components that, for example, allow direct injection into a tank of the sprayer. However, the platform must be easily accessible and ideally should not be obstructed by other attachments of the crop protection sprayer, such as the spray boom.

[0054] This can be achieved by adjusting the height of the boom. A sliding mechanism allows the boom to be moved into driving and filling positions.

[0055] The invention is explained in more detail below with reference to an exemplary embodiment in conjunction with the accompanying drawings. Here, Fig. 1 schematically shows a spatial view of an agricultural machine with a frame and linkage;

[0056] Fig. 2 shows a side view of the agricultural machine from Figure 1;

[0057] Fig. 3 is a top view of the agricultural machine from Figure 1; and

[0058] Fig. 4 shows another spatial view of the agricultural

[0059] Machine from Figure 1.

[0060] In the following description, the same reference symbols are used for the same objects.

[0061] Figure 1 shows a spatial view of an agricultural machine 1 with a frame 2 and a linkage 3.

[0062] Figure 1 shows an agricultural machine 1 for applying spray liquid and / or granular material to a field. Specifically, Figure 1 depicts a field sprayer. However, this is not mandatory; it could also be a seed drill and / or a fertilizer spreader. Furthermore, it could also be other types of agricultural machines 1, such as cultivators, tillage implements, etc.

[0063] The agricultural machine 1 has a frame 2 which supports a platform 9 and a container 11 of the agricultural machine 1 and a height adjustment 4 for a linkage 3 of the agricultural machine 1.

[0064] Furthermore, the agricultural machine 1 has a boom 3, such as a spray boom 3, for arranging application devices, such as spray nozzles.

[0065] Furthermore, the agricultural machine 1 includes a height adjustment 4 for the linkage 3. The height adjustment 4 connects the linkage 3 to the frame 2 and is attached to both the linkage 3 and the frame 2.

[0066] The height adjustment mechanism 4 comprises a first 5 and a second adjustment device 6 for guiding and adjusting the height of the linkage 3 relative to the frame 2. Furthermore, the agricultural machine 1, as shown in Figure 1, has an area 7 for accessing the agricultural machine 1 and / or for a person to climb onto and remain on the machine and / or for accessing a platform 9 of the agricultural machine 1. The area 7 is laterally bounded by the first and second adjustment devices 5, 6 and by the frame 2, or is partially enclosed by the first and second adjustment devices 5, 6 and by the frame 2. The area is large enough to allow a person to remain within it.

[0067] As can be seen in Figure 1, the first and second adjustment devices 5, 6 are spaced apart transversely to the direction of travel F of the agricultural machine 1. As already mentioned, area 6 is positioned or arranged between the first and second adjustment devices 5, 6. A person can be in area 7 and / or climb onto a platform 9 of the agricultural machine 1.

[0068] Figure 2 shows a side view of the agricultural machine 1 from Figure 1.

[0069] It can be seen that the first and second adjusting devices 5, 6 each form a four-bar linkage and / or a four-bar linkage and / or a parallelogram guide.

[0070] Each adjusting device 5, 6 has a first link A which is attached to the frame 2. Furthermore, each adjusting device 5, 6 has a second link B which is attached to a support frame 13 for the linkage 3.

[0071] Furthermore, each adjusting device 5, 6 comprises a third link C and a fourth link D, each connecting the first link A to the second link B. The third and fourth links C, D are pivotally connected to the first and second links A, B.

[0072] As an alternative to the four-bar linkage / four-bar linkage and / or the parallelogram linkage, the first and second adjustment devices 4 can each have a lifting mast or lifting device. The lifting mast or lifting device can have a length-adjustable sliding guide, similar to that of a forklift truck, with which the distance of the linkage 3 to the ground can be changed.

[0073] According to Figures 1 and 2, the agricultural machine 1 has a ladder 8 to overcome a height and to access or climb onto a platform 8 of the agricultural machine 1. The ladder 8 is located in area 7. Specifically, area 7 or the ladder 8 has a step ladder, or the ladder 8 is designed as a step ladder.

[0074] Furthermore, Figures 1 and 2 show that the access ladder 8 of the agricultural machine 1 has several steps for a person's feet. In other words, the access ladder 8 has rungs for climbing up and down, which are fitted into two rails on the left and right. Thus, the access ladder 8 has two rails that are slidable relative to the frame 2. The access ladder 8 of the agricultural machine 1 can also be telescopic, foldable, or extendable.

[0075] Furthermore, Figure 1 shows area 7 in isolation. Figure 1 also shows that area 7, for climbing onto the agricultural machine 1 and / or for climbing and remaining on the agricultural machine 1 and / or for climbing to a platform 9 of the agricultural machine 1, is bounded by six theoretical side faces or has a hexahedron.

[0076] A first theoretical side surface U is formed by the frame 2 or by the agricultural machine 1.

[0077] Furthermore, the height adjustment mechanism 4 has a support frame 13, via which the linkage 3 is connected to the frame 2. A second theoretical side surface V is formed by the support frame 13 or by the linkage 3, wherein the support frame 13 forms a second element B of each adjustment device 5, 6 and connects the two adjustment devices 5, 6 transversely to the direction of travel F (see also Figure 2).

[0078] According to Figure 1 or its right-hand side illustration of a reduced-size area 7 (for improved visibility), the first and second side surfaces U, V are arranged opposite each other.

[0079] When looking at Figures 1 and 2 together, a third and fourth side surface W, X are each formed by two connections C, D and by two links C, D of the two adjusting devices 5, 6, respectively, which movably connect the first side surface U or the frame 2 to the support frame 13. The third and fourth side surfaces W, X are arranged opposite each other.

[0080] Figure 1 further shows that a fifth side surface Y is formed by the ground on which the agricultural machine 1 stands, with a sixth side surface Z being oriented in the same direction as the ground and spaced away from the ground. The sixth side surface Z is 5 meters away from the ground.

[0081] Figure 3 shows a top view of the agricultural machine 1 from Figure 1.

[0082] This shows that the agricultural machine 1 has a platform 9 leading to an access opening 10 of a container 11 of the agricultural machine 1. The platform 9 serves as elevated access for a person to the access opening 10 of the container 11 of the agricultural machine 1. Furthermore, the platform 9 and the access opening 10 of the container 11 of the agricultural machine 1 are arranged relative to each other such that the access opening 10 is within arm's reach of a person, thus enabling a person to open and / or close the access opening 10 from the platform 9.

[0083] As already mentioned, the agricultural machine 1 has a container 11 with an access opening 10 for servicing the agricultural machine 1 and / or for filling the container 11 of the agricultural machine 1, e.g. with liquid, and / or for removal, such as taking samples, material or distribution material of liquid (see Figures 1 and 3).

[0084] Furthermore, Figures 1 and 3 show that the height adjustment 4 has two adjusting devices 12 for moving the first and second adjusting device 5, 6 and / or for moving the second element B of the first and second adjusting device 5, 6 (see also Figure 4).

[0085] The adjusting devices 12 are rotatably mounted on the frame 2 and on the first and second adjusting devices 5, 6. Furthermore, the two adjusting devices 12 are rotatably mounted on the frame 2 and on the first and second adjusting devices 5, 6 such that, along a first direction in which the adjusting devices 12 can be extended, the distance of the second element B of the first and second adjusting devices 5, 6 to the ground increases. Additionally, the two adjusting devices 12 are rotatably mounted on the frame 2 and on the first and second adjusting devices 5, 6 such that, along a second direction opposite to the first, the adjusting devices 12 can be shortened, thereby reducing the distance of the second element B of the first and second adjusting devices 5, 6 to the ground. Figure 4 shows a further three-dimensional view of the agricultural machine 1 from Figure 1.Here, height adjustment 4 is shown more clearly. Below, height adjustment 4 for the linkage 3 of the agricultural machine 1 is described again separately.

[0086] According to Figure 4, the height adjustment 4 has - as already mentioned - a first and a second adjustment device 5, 6 for guiding the linkage 3 of the agricultural machine 1.

[0087] Each adjusting device 5, 6 has a first link A which is attached to the frame 2 of the agricultural machine 1.

[0088] In addition, each adjusting device 5, 6 has a second link B which is attached to the support frame 13 of the linkage 3 of the agricultural machine 1.

[0089] Furthermore, Figure 4 shows that each adjusting device 5, 6 has a third C and fourth link D, each of which is connected to the first link A and to the second link B.

[0090] The two adjusting devices 5, 6, or their third and fourth links C, D, are designed and spatially aligned or spaced apart from each other in such a way that the area 7 for accessing the agricultural machine 1 and / or for a person to access and remain on the platform 9 or the access ramp 8 of the agricultural machine 1 is located in a space between the two adjusting devices 5, 6, or between the first and second links A, B, and between the third and / or fourth links A, B, C, D. This allows a person to access the platform 9 of the agricultural machine 1.

[0091] As is known, the first and second adjusting devices 5, 6 each form a parallelogram guide, wherein the first and second links A, B and the third and fourth links C, D are aligned parallel.

[0092] Alternatively, the first and second adjustment devices 4, 5 may each have a lifting mast or lifting mechanism. The lifting mast or lifting mechanism may have a length-adjustable sliding guide, similar to that of a forklift truck, which allows the distance of the support frame 13 of the linkage 3 to the ground to be changed. As can be seen in Figure 4, the height adjustment device 4 has a support frame 13 for the linkage 3 of the agricultural machine 1, via which the first adjustment device 5 is connected to the second adjustment device 6. The support frame 13 forms the second element B for each adjustment device 5, 6. Furthermore, Figure 4 shows that the two adjustment devices 5, 6 and 6, respectively, are connected by a support frame 13.whose third and fourth links C, D are spaced apart from each other and attached to the support frame 13 and shaped in such a way that a person can move within a space or area 7 spanned by the first, second, third, and fourth links A, B, C, D. In other words, the two adjustment devices 5, 6, or their third and fourth links C, D, are spaced apart from each other and attached to the support frame 13 in such a way that a person can ascend and remain between the first and second and between the third and fourth links A, B, C, D using the access platform 8 of the agricultural machine 1.
