Description

Technical Field

[0001] The invention relates to a feed mixing barrel and a fixed feed mixing device and a feed mixing vehicle having the feed mixing barrel. Background Art

[0002] Stationary feed mixers and feed mixer wagons are agricultural machines used for mixing fodder (animal feed) and, in the case of feed mixer wagons, also for distributing it. These machines are particularly common in animal husbandry, where providing animals (such as cattle) with a calculated, balanced diet is important.

[0003] Feed mixing vehicles known in the art may be towed by a pulling machine (eg a tractor) or be self-propelled. Feed mixing vehicles known in the art comprise a so-called feed mixing bucket for receiving and delivering feed.

[0004] The feed mixing bucket is the component of the feed mixing vehicle that mixes the various feed ingredients. Possible feed ingredients include, for example, hay, silage, grains, trace mineral nutrients and other nutrients required for a balanced diet for animals.

[0005] The mixing of different feed ingredients ensures a homogenous feed mixture, so that all animals receive the same mixture and thus the necessary nutrients. This helps to promote animal health and optimize production, for example, milk production in dairy cows or growth in animals raised for slaughter.

[0006] Additionally, feed mixing carts allow for efficient distribution of feed, saving time and manpower.

[0007] Conventional feed mixing vehicles often provide inadequate mixing and / or take a long time to achieve adequate mixing of feed ingredients.

[0008] Furthermore, it is clear that the amount of feed required is increasing, as agricultural production activities involve raising more animals, which in turn requires more feed. Summary of the Invention

[0009] The present invention is based on the purpose that provides feed mixing bucket and feed mixing vehicle, and it overcomes the above-mentioned disadvantages at least in part.In addition, the feed mixing bucket should be easy to manufacture and low in price.

[0010] According to the invention, this object is achieved by a feed mixing bucket and a feed mixing cart as defined in the independent claims. Further aspects of the invention are described in the dependent claims and in the following description.

[0011] In particular, the object is achieved by a feed mixing bucket for a feed mixing vehicle.The feed mixing bucket is used to receive feed, such as grass, hay, silage, concentrated feed, grain, feed supplement and / or the like.

[0012] The feed mixing barrel is further adapted to include at least one vertical mixing auger. The feed mixing barrel can also be adapted to accommodate a plurality of vertical mixing augers, such as 2 or 3 vertical mixing augers. In particular, the vertical mixing augers can be arranged in a row, the row extending along the direction of travel.

[0013] The feed mixing bucket comprises a bottom plate and a peripheral wall extending upward from the bottom plate. At least one aperture, in particular a closable aperture for distributing feed, can be provided in the bottom plate and / or the peripheral wall.

[0014] The peripheral wall includes a front peripheral wall section, a rear peripheral wall section, a first lateral peripheral wall section, and a second lateral peripheral wall section. In the case of a feed mixing bucket for a feed mixing cart, i.e., a feed mixing cart bucket, when the feed mixing cart bucket is mounted on the feed mixing cart, the front peripheral wall section points in the travel direction F of the feed mixing cart. The front peripheral wall section is arranged opposite the rear peripheral wall section, and the first lateral peripheral wall section is arranged opposite the second lateral peripheral wall section.

[0015] The peripheral wall can be made of metal, in particular steel, for example chromium-nickel steel.

[0016] In one aspect, the front peripheral wall segment includes at least one wall element and two corner elements. In another aspect, the rear peripheral wall segment includes at least one wall element and two corner elements. The present invention also includes the option of both the front peripheral wall segment and the rear peripheral wall segment including at least one wall element and two corner elements. If only the front peripheral wall segment or the rear peripheral wall segment includes at least one wall element and two corner elements, the corresponding opposing peripheral wall segment can have a different design, for example, a semicircular design.

[0017] Furthermore, the first corner element is connected to the first lateral peripheral wall segment and the second corner element is connected to the second lateral peripheral wall segment. Thus, the corner elements connect the front (and / or rear) peripheral wall segment to the corresponding lateral peripheral wall segment, thereby forming a circumferential peripheral wall.

[0018] The at least one wall element is plate-shaped and therefore has no significant curvature.

[0019] Furthermore, the at least one wall element encloses an angle α (or β) with a horizontal direction R, which is oriented perpendicular to the central plane M, said angle being in the range of ≧0° to ≦30°.

[0020] The central plane M is defined by the lateral peripheral wall sections and may in particular be a plane of symmetry.In case the feed mixing bucket constitutes a feed mixing vehicle bucket, the horizontal direction R is oriented transversely with respect to the direction of travel F.

[0021] In particular, the angle can be provided in the range of 0° to 25°, or in the range of 0° to 20°, or in the range of 0° to 15°, or in the range of 0° to 10°, or in the range of 0° to 5°, or in the range of 0° to 3°, or in the range of 1° to 2°. If the angle is 0°, the wall element is thus arranged substantially transversely to the central plane and the direction of travel, respectively. However, the wall element can be inclined in a direction lying in the central plane, or in the direction of travel F, or against the direction of travel F, respectively (see angle φ).

[0022] Compared to conventional bucket-shaped buckets (e.g., with a semicircular front or rear area), plate-shaped wall elements allow for a higher feed mixing bucket capacity without requiring any changes to the width, length, and / or height of the feed mixing bucket. This is advantageous, as width and height are particularly restricted when considering that feed mixing carts typically tend to meet road approval requirements. The increased capacity allows for a larger amount of feed to be introduced, allowing more animals to be fed using a single mixing cart.

[0023] Furthermore, the plate-shaped wall elements make it easier to fill the feed mixing bucket, as the feed can be filled into the feed mixing bucket through the generally straight edge of the at least one wall element. This is particularly advantageous when a front loader (or a corresponding front loader bucket or forklift) is used for the filling process and / or when a conveying device (such as a conveyor belt or blower) is involved in the filling process. In this case, for example, a very wide bucket or conveyor belt can be used for filling, thereby preventing feed from overflowing from the sides. This can increase the filling speed.

[0024] Furthermore, one or more plate-shaped wall elements can reduce the amount of material required to achieve a large vat volume. This results in cost savings and weight reduction.

[0025] Furthermore, plate-shaped wall elements can be easily connected to other parts (wall elements, corner elements, and / or the like) because the corresponding connecting edges of the wall elements can be designed as straight parts. This connection can be implemented by welding, riveting, screwing, gluing, and / or other methods. Consequently, the connection can be implemented cost-effectively and reliably, and in particular, can also be automated (e.g., using a (welding) robot).

[0026] The corner element may be curved and / or folded. In the case of a folded edge, multiple folds may be arranged next to each other to form a curved corner element. Likewise, multiple separate independent parts may be joined (e.g., welded, riveted, screwed, glued, and / or otherwise joined) together to form a corner element. The corner element preferably has a radius r at its upper end. o, which is smaller than the radius r of the corner element at the bottom end u Radius r o The radius r may be, for example, in the range of 50 mm to 1000 mm. u The radius r can be in the range of 500mm to 2000mm. o The radius r may also be within the range of 200 mm to 800 mm, for example. u It can also be in the range of 900mm to 1500mm.

[0027] In a further aspect of the present invention, the front peripheral wall section and / or the rear peripheral wall section comprises at least two wall elements. The at least two wall elements are plate-shaped. Each of the at least two wall elements encloses an angle in the range of ≥0° to ≤30° with the horizontal direction R. In particular, the angle may be in the range of 0° to 25°, or in the range of 0° to 20°, or in the range of 0° to 15°, or in the range of 0° to 10°, or in the range of 0° to 5°, or in the range of 0° to 3°, or in the range of 1° to 2°.

[0028] In this case, the wall elements can be arranged at different angles or they can enclose substantially equal angles (in absolute value) with the horizontal. In one aspect, the wall elements are arranged symmetrically with respect to a center line, which is oriented along the direction of travel.

[0029] In a first embodiment, the front peripheral wall segment and / or the rear peripheral wall segment comprises two wall elements, each wall element enclosing an angle with the horizontal ranging from ≥0° to ≤5°. The two wall elements can be arranged directly adjacent to each other and can be connected to each other.

[0030] In a second embodiment, the front peripheral wall segment and / or the rear peripheral wall segment comprises three wall elements, each of which encloses an angle α with the horizontal in the range of ≥0° to ≤5°. In this case, the first wall element can be arranged at an angle α≠0, the second wall element can be arranged transversely to the direction of travel, and the third wall element can be arranged at an angle “−α”, wherein the second wall element is arranged between the first and third wall elements and is connected to the first and third wall elements.

[0031] Adjacent wall elements can be connected to each other (e.g., welded, riveted, screwed, glued, and / or connected in some other manner), or they can be made integrally (i.e., made as one piece). In such an integral design, adjacent wall elements can, for example, be formed from a single piece of metal sheet, wherein the two wall elements abut each other at a fold.

[0032] In particular, two adjacent wall elements can form an edge. This edge can be a connecting edge (e.g., a weld seam) or a folded edge (e.g., a fold). The edge is preferably arranged in a vertical plane and points away from the axis of rotation of the vertical mixer auger. This means that when viewed from the outside of the feed mixing drum, the edge is convex. The edge further increases the volume. Furthermore, the edge stabilizes the corresponding peripheral wall section, allowing it to be designed with a thinner wall thickness. This allows for the use of less material, thereby reducing weight and costs.

[0033] In one aspect of the invention, at least one corner element (or two corner elements) of the front and / or rear peripheral wall segments forms a mixing area. This improves feed mixing and / or shortens mixing time.

[0034] In at least one mixing zone, the radial horizontal distance between the rotation axis of the vertical mixing auger assigned to the mixing zone and the peripheral wall is greater than the radial horizontal distance between the rotation axis and a segment of the peripheral wall formed by a wall element directly adjacent to the corner element. This wall element can be a wall element of a front peripheral wall segment, a rear peripheral wall segment, or a lateral peripheral wall segment.

[0035] In the mixing zone, feed conveyed vertically (upward) can be radially discharged from the mixing auger and fall downward. The area below the mixing zone, where the distance between the peripheral wall and the axis of rotation is smaller, returns the feed to the mixing auger, causing it to be conveyed vertically upward again. This achieves excellent mixing.

[0036] In one aspect, at least one wall element of the front and / or rear peripheral wall segments and / or the first and / or second lateral peripheral wall segments has a smaller circumference in the area near the base of the feed mixing bucket than in the upper area. In other words, the wall elements widen toward the top. For example, one or more wall elements may be trapezoidal or triangular. The upper circumference may, for example, be at least 3 times, at least 4 times, at least 5 times, at least 6 times, or at least 7 times the circumference near the base.

[0037] In this way, a feed mixing bucket that widens towards the top can easily be achieved. This increases the ease of filling and improves mixing.

[0038] Furthermore, the wall elements of the front and / or rear peripheral wall segments can form an upper edge, the width of which corresponds to 0.5 to 0.9 times or 0.6 to 0.7 times the total width of the feed mixing bucket. The width of the upper edge facilitates filling the feed mixing bucket by a front loader and / or by a conveying device such as a conveyor belt or a blower.

[0039] In a further aspect, the feed mixing barrel is suitable for accommodating at least two (or at least three) vertical mixing augers. In this case, the first lateral peripheral wall section may include a first guide element, which protrudes into the feed mixing barrel between the vertical mixing augers. Correspondingly, the second lateral peripheral wall section may additionally or alternatively include a second guide element, which protrudes into the feed mixing barrel between the vertical mixing augers and is preferably arranged opposite the first guide element. The guide element can be made of sheet metal (in particular steel sheet) and can be welded to the wall element or multiple wall elements of the lateral peripheral wall section. The guide element can also be implemented by forming. One or more guide elements guide the feed in the direction of the vertical mixing augers to improve mixing.

[0040] In one aspect, the front and / or rear peripheral wall segments can be tilted at an angle φ relative to the vertical plane. Angle φ can be in a range of 10° to 20°, or in a range of 12° to 18°, or in a range of 14° to 16°. The lateral peripheral wall segments can be tilted at an angle δ relative to the vertical plane, wherein angle δ is in a range of 0° to 10°, or in a range of 3° to 8°, or in a range of 4° to 5°. In one aspect, angle φ can be greater than angle δ. Results have shown that this tilting of the respective peripheral wall segments results in better mixing of the feed.

[0041] In a further aspect, the feed mixing bucket includes a peripheral wall extension. The peripheral wall extension extends from the peripheral wall, particularly on the side of the peripheral wall opposite the base plate. The peripheral wall extension thus increases the overall height of the feed mixing bucket and, therefore, the volume of the feed mixing bucket. The height of the peripheral wall extension may be 10% to 50% or 15% to 30% of the height of the peripheral wall. Furthermore, the height of the peripheral wall extension may be constant or variable. In particular, the peripheral wall extension is adapted to be arranged over the entire circumference and / or substantially vertically.

[0042] The peripheral wall extension may be made of the same material as the peripheral wall and permanently connected to the peripheral wall.The peripheral wall may also be plug-mounted.

[0043] In addition, the feed mixing bucket may comprise a peripheral wall edge. In particular, the peripheral wall edge may be circumferential or may be arranged only in certain areas. The peripheral wall edge is connected to a peripheral wall extension on a side opposite to the peripheral wall.

[0044] The peripheral wall edge can be implemented in different ways. For example, the peripheral wall edge can be arranged substantially vertically, thereby further increasing the total height of the feed mixing bucket and thus increasing the volume. The height of the peripheral wall edge can be 5% to 30% or 10% to 25% of the height of the peripheral wall.

[0045] In another embodiment, the peripheral wall edge extends inwardly from the peripheral wall extension and optionally extends in a vertical direction. The cross-section of the peripheral wall edge can be substantially straight, curved, or folded. Due to the inward extension, the peripheral wall edge protrudes inwardly, and the overhanging portion prevents the feed from being thrown out of the feed mixing bucket during mixing.

[0046] The peripheral wall extension and / or the peripheral wall edge can be made of plastic, preferably a composite material. This helps to reduce weight. The plastic can be resilient so that placing a bucket or a conveying device on the feed mixing bucket does not damage the feed mixing bucket.

[0047] The object is also achieved by a stationary feed mixing device, wherein the feed mixing device comprises at least one vertical mixing auger and a feed mixing barrel, wherein the at least one vertical mixing auger is arranged in the feed mixing barrel.

[0048] The object is also achieved by a feed mixing vehicle, comprising a chassis, at least one (or at least two or at least three) vertical mixing augers and a feed mixing barrel, wherein the feed mixing barrel is designed as described above. At least one vertical mixing augers is arranged in the feed mixing barrel.

[0049] The chassis may be a trailer chassis. The feed mixer may therefore be a towed feed mixer.

[0050] Furthermore, the feed mixing vehicle may comprise a traction drive and may thus be a self-propelled feed mixing vehicle. A self-propelled feed mixing vehicle may be adapted to be driven (partially) autonomously and / or adapted to be manually controlled.

[0051] Optionally, the feed mixing vehicle comprises a feed receiving device (eg, a silage grinder) adapted to receive feed and convey the feed to a feed mixing bucket via a conveying device (eg, a conveyor belt or a blower). BRIEF DESCRIPTION OF THE DRAWINGS

[0065] Figures 1A to 1D A first embodiment of a feed mixing bucket 50 according to the present invention is shown, which may be a feed mixing vehicle bucket or a stationary feed mixing bucket.

[0066] The feed mixing bucket 50 comprises a bottom plate 100 and a peripheral wall 200 extending upward from the bottom plate 100. Optionally, a peripheral wall extension 300 is provided, which increases the overall height of the feed mixing bucket. In addition, a peripheral wall edge 400 may be provided on the peripheral wall extension 300.

[0067] The peripheral wall 200 includes a front peripheral wall section 210, a rear peripheral wall section 220, a first lateral peripheral wall section 230, and a second lateral peripheral wall section 240. The lateral peripheral wall sections 230 and 240 define a central plane M (see FIG. Figure 1B ). In this example, the central plane is the symmetry plane.

[0068] In particular, Figure 1A and 1B As shown, the front peripheral wall section 210 includes wall elements 212, 214 and corner elements 252, 254. The rear peripheral wall section 220 disposed opposite the front peripheral wall section 210 includes wall elements 222, 224 and corner elements 256, 258.

[0069] The lateral peripheral wall sections 230 , 240 comprise lateral wall elements 232 , 234 , 236 and 242 , 244 , 246 , respectively.

[0070] In the embodiment shown here, the wall elements 212, 214, 222, 224, 232, 234, 236, 242, 244, 246 are plate-shaped and have a trapezoidal or triangular shape. Adjacent wall elements can be connected to each other (in particular, they can be welded, riveted, screwed, glued and / or similarly connected together) or they can be formed integrally.

[0071] In this embodiment, the corner elements are connected to the lateral peripheral wall sections 230, 240. The corner elements 252, 254, 256, 258 can be bent or folded so that they are substantially arc-shaped. Moreover, the corner elements can have a radius r at the upper end. o , which is smaller than the radius r of the corner element at the bottom end u .

[0072] In particular, Figure 1B As shown in the plan view, at least one wall element 212, 214; 222; 224 of the front peripheral wall segment 210 or the rear peripheral wall segment 220 is oriented such that it encloses an angle α or β with a horizontal direction R perpendicular to the central plane M or transverse to the direction of travel F, wherein the angle α or β is in a range of ≥0° to ≤30°. In particular, the angle can be in a range of 0° to 25°, or in a range of 0° to 20°, or in a range of 0° to 15°, or in a range of 0° to 10°, or in a range of 0° to 5°, or in a range of 0° to 3°, or in a range of 1° to 2°. Here, the angles α and β are each approximately 3°.

[0073] Central lateral wall element 234 can be oriented substantially along the direction of travel. The other two lateral wall elements 232 and 236 are oriented so that they enclose an angle γ with the direction of travel F, wherein the angle γ is in the range of ≥0° to ≤5°. Here, the angle γ is approximately 3°. Lateral wall elements 242, 244, and 246 can be arranged accordingly.

[0074] Also like Figure 1A and 1B As shown, two adjacent wall elements 212, 214 (222, 224) form an edge 216 (226), which is away from the rotation axis 112 of the vertical mixing auger (radius r M ) points in the direction of the sun, and is therefore convex.

[0075] The corner elements 252, 254, 256, 258 also form mixing areas 152, 154; 156, 158. In the respective mixing areas 152, 154; 156, 158, the radial horizontal distance between the rotation axis 112 of the associated vertical mixing auger and the peripheral wall (given by the radius r M ) is greater than the radial horizontal distance between the axis of rotation 112 and the section of the peripheral wall 200 formed by the wall elements 212, 214; 222, 224 arranged directly adjacent to the corner elements 252, 254; 256, 258. This applies in particular to the gap above the base plate 100 of the feed mixing bucket.

[0076] like Figure 1C As shown, the lateral peripheral wall sections 230 , 240 may be inclined at an angle δ relative to a vertical plane, wherein the angle δ is in the range between 0° and 10°, or in the range between 3° and 8°, or in the range between 4° and 5°.

[0077] like Figure 1C As shown, the front peripheral wall segment and / or the rear peripheral wall segment can be inclined relative to the vertical plane at an angle φ. The angle φ can be in the range of 10° to 20°, or in the range of 12° to 18°, or in the range of 14° to 16°. As shown in the figure, the angle φ can be greater than the angle δ.

[0078] like Figure 1C In an exemplary manner, the wall elements 212 , 214 of the front peripheral wall segment 210 (and / or similarly the wall elements of the rear peripheral wall segment 220 ) form an upper edge, wherein the upper edge has a width b vo Width b vo By each width b v1 and b v2 Composition. Width b vo It can correspond to 0.5 to 0.9 times or 0.6 to 0.7 times the total width b of the feed mixing bucket 50. It is also shown that the wall element can widen towards the top so that the lower width b vu Less than b vo .

[0079] Figure 1D Length and height ratios are shown. The peripheral wall 200 has a height h1. The height h2 of the peripheral wall extension 300 may be 10% to 50% or 15% to 30% of the height h1 of the peripheral wall 200. The height h3 of the peripheral wall edge 400 may be 5% to 30% or 10% to 25% of the height h1 of the peripheral wall 200.

[0080] The length l of the feed mixing barrel 50 depends in particular on the number of vertical mixing augers, which can be seen by comparing the first embodiment (see Figure 1D ) and the third embodiment (see Figure 3C ). In particular, this length can be adjusted by suitable selection and dimensioning of the lateral wall elements 232, 234, 236, which in the present case have lengths l1, l2, l3 in the upper region, which together add up to the total length l of the lateral wall segment 230. o The total length l in the upper area o Greater than the total length l in the lower area near the base u .

[0081] Figure 2 A schematic top plan view of another feed mixing bucket (second embodiment) is shown, which can also be implemented as a feed mixing vehicle bucket. In order to avoid unnecessary redundancy, the same reference numerals define the previously referenced Figures 1A-1D In the following, we will discuss the differences in particular.

[0082] The feed mixing bucket (second embodiment) includes peripheral wall sections with different configurations. The front peripheral wall section 210 is referenced Figures 1A-1D The configuration shown in FIG. 2 is shown in FIG. 2 , and the shape of the rear peripheral wall section 225 is substantially semicircular. In another embodiment not shown, the rear peripheral wall section may be as shown in FIG. Figures 1A-1D As shown, the front peripheral wall section is shaped substantially semicircular.

[0083] Figures 3A-3C Another embodiment of a feed mixing bucket is shown, which can also be implemented as a feed mixing vehicle bucket. Figures 1A-1D In the following, we will discuss the differences in particular.

[0084] Figures 3A-3C The feed mixing barrel shown in FIG is suitable for accommodating two vertical mixing augers. Therefore, two rotation axes 112, 122 are shown in these figures. Each vertical mixing augers is assigned to a bottom plate section 110, 120 and is arranged in a row.

[0085] To improve mixing, the first lateral peripheral wall section 230 comprises a first guide element 238, which projects into the feed mixing barrel between the vertical mixing augers and separates the two floor sections 110, 120. Correspondingly, the second lateral peripheral wall section 240 comprises a second guide element 248, which is arranged opposite the first guide element 238.

[0086] exist Figures 1A-1D and Figures 3A-3C The feed mixing bucket shown in FIG includes an inwardly directed curved peripheral wall edge 400. This peripheral wall edge is optional. Figure 4As shown, it is also possible to provide a peripheral wall edge 500 pointing in the vertical direction, or to completely abandon the peripheral wall edge (see Figure 5 ).

[0087] Figure 6 A self-propelled feed mixing vehicle 1 is shown. The self-propelled feed mixing vehicle comprises Figures 3A-3C 1 and 2. A feed mixing drum (or feed mixing vehicle drum) 50 and a chassis 10 with a cab 12 are shown. In addition, a feed receiving device 14 (in this example, a silage grinder) is provided. The silage grinder is suitable for grinding silage from a silage warehouse and conveying it to the feed mixing drum 50 using a conveying device 16 (e.g., a conveyor belt).

[0088] Figure 7 A towed feed mixing vehicle 2 is shown. Here, a feed mixing bucket (or feed mixing vehicle bucket) 50 is mounted on a trailer chassis 20. The towed feed mixing vehicle 2 can be towed via a tow bar 22, for example, using a tractor (or another tractor).
