Description

[0001] Mudguard, mudguard unit and agricultural implement with a mudguard unit

[0002] The invention relates to a mudguard according to the preamble of claim 1, a mudguard unit according to the preamble of claim 9 and an agricultural implement according to the preamble of claim 14.

[0003] Agricultural implements, particularly spreaders, are often equipped with mudguards attached to the front of the implement to protect it from dirt kicked up by the tractor's wheels during operation on agricultural land. In this way, one or more mudguards can protect the implement from contamination and / or damage caused by flying debris.

[0004] Furthermore, it is common practice that agricultural machinery can be supplemented with additional equipment and / or requires further equipment for operation, which is usually carried separately during a work process on an agricultural area, either on the outside of the agricultural machinery and / or in the driver's cab of the tractor for the machinery, for example in a bag.In practice, carrying equipment for implements separately and / or attaching it externally to the implement has proven disadvantageous, as externally attached equipment is exposed to environmental influences, such as precipitation and / or contamination from kicked-up dirt, and / or equipment carried separately in the tractor cab takes up space and can consequently restrict the comfort and safety of the machine operator. The object of the invention is therefore to improve the storage options on agricultural implements for one or more pieces of equipment.

[0005] The problem is solved by a mudguard of the type mentioned above, wherein the mudguard includes a receiving area for receiving one or more pieces of equipment for the attachment machine.

[0006] The mudguard's integrated storage area for one or more pieces of equipment for the implement allows one or more mudguards on agricultural implements, particularly spreaders, which are usually equipped with one or more mudguards anyway, to be used as storage space for these items. This eliminates the need to carry equipment separately in the operator's cab and / or attach it elsewhere on the implement's exterior. This saves space in the cab, increasing operator comfort, and / or prevents equipment from becoming soiled when mounted externally on the implement.

[0035] Fig. 1 shows an agricultural implement 200 according to the invention, which is designed as a mounted agricultural spreader, in particular as an agricultural twin-disc centrifugal fertilizer spreader. The agricultural implement 200 comprises two mudguards 10 according to the invention, which are arranged at the front of the implement 200 below a hopper 204 for agricultural spreading material, wherein a first mudguard 10 of the two mudguards 10 is attached to the left side of a coupling device 202 and a second mudguard 10 is attached to the right side of the coupling device 202 at the front of the implement 200. By means of the coupling device 202, the agricultural implement 200 can be attached to a carrier vehicle for the implement 200, in particular to a tractor.The mudguards 10 are arranged on the implement 200 in such a way that dirt which is thrown up by the wheels of a tractor during a work operation on an agricultural area in front of the implement 200 is partially or completely deflected off the mudguards 10 in order to protect the agricultural implement 200 from contamination and / or damage caused by dirt thrown up by the tractor.

[0036] Fig. 2 shows a mudguard 10 according to the invention in a perspective front view, wherein the mudguard 10 is designed to be mounted on an agricultural implement 200, as shown in Fig. 1, and to protect the agricultural implement 200 from dirt kicked up by a tractor during a work operation on agricultural land. The mudguard 10 has a protective surface 12 at its front, which is supported by a front wall 16 of the mudguard 10 and is designed to catch the dirt kicked up by a tractor by deflecting the dirt off the protective surface 12, thus protecting the implement from the dirt.

[0037] To increase the resistance and stability of the front wall 16 and consequently the protective surface 12, so that the dirt trap 10 is not deformed and / or damaged by dirt impacting the protective surface 12, stabilizing recesses 20 are arranged in the front wall 16 of the dirt trap 10 in the area of ​​the protective surface 12. The illustrated dirt trap 10 comprises several stabilizing recesses 20, which are arranged next to each other and / or one above the other and / or diagonally to each other and / or spaced apart from each other, wherein the stabilizing recesses 20 are in particular designed as hexagonal and / or diamond-shaped indentations in the front wall 16 of the dirt trap 10.

[0038] Furthermore, the mudguard 10 includes a closing device 30 by means of which an opening 24 in the mudguard 10 can be opened and closed. Figure 2 shows an embodiment of the mudguard 10 which is designed for right-side mounting on an attachment 200, such that the closing device 30 for closing the opening 24 is located in a side wall 26 of the mudguard 10, positioned to the right of the front wall 16, in the illustrated embodiment of the mudguard 10. Figure 2 also shows a state of the mudguard 10 in which the opening 24 in the mudguard 10, in particular in the side wall 26 of the mudguard 10, is closed by means of a cover 32 of the closing device 30.The locking device 30 also includes a locking mechanism 36, which is designed in particular as a snap lock and / or a clamping lock and secures the cover 32 in the closed position, thus preventing unintentional opening of the opening 24. To open the opening 24 by means of the locking device 30, the locking device 30 also includes two hinges 34 arranged vertically one above the other and spaced apart from each other, which allow the cover 32 to pivot for opening and closing the opening 24. The cover 32 of the locking device 30 is thus designed as a flap, pivotable via hinges 34 and lockable by means of the locking mechanism 36, for opening and closing the opening 24 in the side wall 26 of the dirt trap 10.

[0039] Figure 3 shows a perspective view of the rear of the dirt trap 10, revealing a rear wall 18 of the dirt trap 10. Several boundary elements 22a to 22e, formed as hollow bodies within the rear wall 18, are visible on the rear of the dirt trap 10. These boundary elements 22a to 22e can be subsequently inserted into the body of the dirt trap 10 after an injection molding process by a forming process, particularly during the manufacturing of the dirt trap 10. The boundary elements 22a to 22e are specifically designed as kiss-off pieces. Boundary elements 22a and 22b are arranged horizontally side-by-side and spaced apart in a line. Boundary elements 22c and 22d are arranged vertically one above the other and spaced apart in a line.The boundary body 22e is located in the lower area of ​​the rear wall 18 and is oriented vertically like the boundary bodies 22c and 22d.

[0040] Fig. 4 shows the mudguard 10 in a side view, in which the side wall 26 of the mudguard 10 is visible. In the illustrated representation of the mudguard 10, the opening 24 of the mudguard 10 in the side wall 26 is shown in an open state, in which the cover 32 of the closing device 30 is pivoted by means of the hinges 34 such that the opening 24 in the side wall 26 of the mudguard 10 is completely free, so that a receiving area 14 inside the mudguard 10, which provides storage space for equipment 102 for the attachment 200, is accessible through the opening 24. The dirt trap 10 is therefore designed as a double-walled hollow body, wherein the receiving area 14 inside the dirt trap 10 is limited, in particular to the front by the front wall 16, to the rear by the back wall 18, to the sides by side walls 26 and above and below by further walls.

[0041] The closing device 30 is further designed such that the interior of the dirt trap 10, in particular the receiving area 14 of the dirt trap 10, is protected from the ingress of moisture and / or liquids and / or contamination when the closing device is closed, i.e., when the opening 24 is closed by means of the cover 32. In this way, equipment 102 arranged in the receiving area 14 is protected from contamination and / or damage and / or moisture, especially during work processes using an attachment 200. For this purpose, the dirt trap 10 comprises sealing areas 38a, 38b, wherein sealing area 38a is a strip-shaped area of ​​the side wall 26 surrounding the opening 24, and sealing area 38b is an area on the inside of the cover 32 facing the opening 24, located in the edge region of the cover 32 and corresponding to sealing area 28a.

[0042] In the closed state of the locking device 30, the sealing areas 38a, 38b are in overlap and are pressed together in contact, wherein a circumferential seal 40, in particular a sealing lip, for example a rubber seal, is arranged in the sealing area 38b of the cover 32, which in the closed state is pressed against the sealing area 38a circumferentially around the opening 24, so that the opening 24 is sealed watertight and / or dustproof.

[0043] Furthermore, the opening 24 in the side wall 26 of the dirt trap 10 is designed such that the opening 24 includes a grip recess 28, which is designed as a section-wise extension of the opening 24 and facilitates the insertion and / or removal of equipment items 102 through the opening 24 and, in particular, the gripping of equipment items 102 arranged in the receiving area 14, for example by a machine operator.The grip recess 28 makes it easier in particular to grasp equipment items 102 designed as collection devices 104, especially collection devices 104 designed as collection mats, since the grip recess 28 is arranged in such a way that it corresponds to grip recesses in collection devices 104 which are arranged in the receiving area 14 of the dirt trap 10, so that in particular a mat package consisting of several collection devices 104 designed as collection mats can be grasped more easily and transported through the opening 24.

[0044] Furthermore, as can be seen in Fig. 4, the limiting bodies 22a to 22e project from the rear wall 18 into the receiving area 14, which is arranged in a space between the rear wall 18 and the front wall 16. The limiting bodies 22a to 22e extend to the inside of the front wall 16, with the ends of the limiting bodies 22a to 22e facing the front wall 16 contacting the inside of the front wall 16 at least partially and / or being connected to the inner wall of the front wall 16 at least partially, in particular by a material bond, for example by fusing. Figure 4 also shows that the stabilizing recesses 20 in the front wall 16 project at least partially into the space between the front wall 16 and the rear wall 18, in particular into the receiving area 14 of the dirt trap 10.The inwardly projecting stabilizing recesses 20 can be fused, at least in some areas, with the inwardly projecting limiting bodies 22a to 22e.

[0045] Figures 5 to 8 show a mudguard unit 100 according to the invention, each comprising a mudguard 10 and one or more accessories 102 for the attachment 200. In Figures 5 to 8, the mudguard 10 is shown with an accessory 102 arranged in the receiving area 14 of the mudguard 10. The mudguard 10 is shown in a perspective view from the front with the front wall 16 hidden, so that the space between the front wall 16 and the rear wall 18 of the mudguard 10, and consequently the receiving area 14 with the respective accessory 102 arranged in the receiving area 14, is visible. Figure 5 shows a mudguard unit 100 comprising a mudguard 10 and several accessories 102, designed as collection devices 104, arranged in the receiving area 14 of the mudguard 10.The collection devices 104 are designed as collection mats for collecting agricultural spreading material on a usable area, wherein several flat collection mats lying next to each other are arranged as a common mat package in the receiving area 14 of the dirt trap 10 essentially parallel to the front wall 16 and the rear wall 18 and extend vertically between the opening 24 in the dirt trap 10 and the boundary bodies 22c, 22d.

[0046] The receiving area 14 of the dirt trap 10 comprises two receiving sub-areas 42a, 42b, wherein the receiving sub-area 42a is limited downwards and rearwards by the limiting bodies 22a to 22d and forwards by the closing device 30, wherein in particular the limiting bodies 22a to 22d form a contour, so that the receiving sub-area 42a is adapted to the geometry of equipment items 102 designed as collecting devices 104, so that the collecting devices 104 are received by the receiving sub-area 42a in such a way that the collecting devices 104 can be arranged in the receiving sub-area 42a essentially without play or with a play of approximately 4 mm and / or can be easily and essentially without force inserted into the receiving sub-area 42a through the opening 24 and / or removed from the receiving sub-area 42a through the opening 24.

[0047] The collecting devices 104 are arranged essentially in alignment with the opening 24, so that they can be inserted and removed through the opening 24 by means of a linear movement. The limiting bodies 22c, 22d serve as rear stops, limiting the insertion of the collecting device 104 into the receiving area 14. The limiting bodies 22a, 22b serve as lower limiting bodies, and the collecting devices 104 can act as guides for the limiting bodies 22a, 22b during insertion and removal through the opening 24, allowing the collecting devices 104 to slide over the limiting bodies 22a, 22b during insertion and removal.

[0048] Figure 6 shows a dirt trap unit 100 comprising a dirt trap 10 and an equipment item 102 designed as a measuring device 106. The measuring device 106 is designed as a funnel-shaped measuring cup for measuring the quantity and / or volume of collected agricultural grit. Furthermore, the measuring device 106 is arranged in the receiving section 42b of the receiving section 14 inside the dirt trap 10, wherein the receiving section 42b is located in the lower part of the interior of the dirt trap 10 and below the receiving section 42a, which is adapted for receiving collecting devices 104.The receiving area 42b is sectionally bounded by the limiting bodies 22a, 22b, 22e, wherein a recess is arranged between the limiting body 22a and the opening 24 in the side wall 26 of the dirt trap 10, through which equipment items 102, for example, the measuring cup, can be inserted into and / or removed from the receiving area 42b.
