Description

Technical Field

[0001] The present invention relates to a device for transporting root crops, comprising a carrying device that rotates in a rotational direction during operation. The carrying device forms at least one receiving area and is used to carry the root crops. In addition, the device comprises at least one transverse separating element that extends at least partially in the transverse direction. The transverse separating element defines the receiving area in the rotational direction. The receiving area adjoins an interior space from the outside, and the interior space extends laterally inside the interior space. The interior space side extends parallel to the transverse direction and, in a side view, extends only in the rotational direction. In a side view, at least one raised portion of the transverse separating element is arranged outside the interior space. Background Art

[0002] During operation, the tuber crops lie flat on the support device and partially rotate with the device. The transverse separating element provides a barrier for the at least one tuber crop arranged in the receiving area and prevents or hinders the tuber crop from escaping from the receiving area during operation. In a transverse direction, the receiving area typically extends at least substantially across the entire width of the device. Movement of the at least one tuber crop is possible within the receiving area.

[0003] A disadvantage of known devices of this type is that, during operation, a large number of root crops in the same receiving area results in the root crops being arranged in multiple layers on the carrier device, with the root crops being arranged in a circular pattern in the receiving area for efficient use of the device. In particular, due to the tilting of the device that typically occurs during operation, the root crops in one portion of the receiving area tend to accumulate and overlap one another there, while another portion of the receiving area is free of root crops. This makes sorting or controlling the root crops and finding foreign objects to be sorted out difficult. Summary of the Invention

[0004] The object of the present invention is to provide a device of the generic type which simplifies the sorting or control of the root crops transported thereby.

[0005] According to the invention, the device has at least one longitudinal separating element, which extends at an angle, in particular at a right angle, to the direction of extension of the transverse separating element and parallel to the side surfaces of the interior space. In side view, the raised portion of the longitudinal separating element is arranged outside the interior space. The longitudinal separating element separates two transversely adjacent receiving areas from one another.

[0006] This design of the device makes it possible to achieve, with the same device width, increasingly narrower receiving areas in the transverse direction, which in each case accommodate a smaller number of tubers while maintaining the same conveying power. In particular, when the device is ascending or when the device is tilted about a tilting axis at least partially parallel to the conveying direction, the likelihood of tubers accumulating on the carrier device due to their displacement in the transverse direction is reduced. Compared to increasing the number of transverse separating elements, by which the displacement of the harvested material in the direction of rotation can be reduced if necessary, it is also ensured that tubers located on one side of the device or longitudinal separating element remain on this side during the rotation and that the screening personnel positioned on the corresponding side can always access the tubers or any foreign objects therein.

[0007] The device is designed to be pivotable, i.e., closed in the direction of rotation, wherein two corresponding end regions connected to each other in the direction of rotation and complementary connecting elements can be disconnected from each other, particularly for disassembly. The device is particularly designed as a belt or conveyor belt that is bendable about a bending axis parallel to the transverse direction. During operation in accordance with regulations, at least a portion of the transported tuber crops is in direct contact with the supporting device. During operation, the supporting device preferably extends below the tuber crops. The transverse direction is a direction at right angles to the direction of rotation, and the width of the device is measured in the transverse direction. The interior space side faces are imaginary surfaces and extend in the transverse direction, particularly over the main or entire width of the device. In a side view oriented in the transverse direction, the interior space side faces are shown linearly. When the device is tensioned, i.e., when viewed in a partially straight direction in the side view, the interior space side faces are flat in the corresponding section approximately between the two deflecting rollers. The receiving area in which the tuber crops are located during operation is adjacent to the interior space in this manner, in contact with the interior space side faces but not intersecting them. In particular, the receiving areas contact the interior side surfaces in a point-shaped, line-shaped or area-shaped manner.

[0008] Viewed in the rotational direction and / or in the transverse direction, the device preferably has at least three, particularly preferably at least five, in particular at least ten receiving areas next to one another. These receiving areas adjoin one another in the transverse direction or in the rotational direction.

[0009] Preferably, at least one receiving area is at least partially, in particular completely, shaped like a pot or trough. This shape is not continuous, that is, closed, but rather is formed by support points arranged along the shape and formed by the support device. The receiving area is thus open outward from the interior. This design of the receiving area counteracts movement of the root crops located therein, in particular rolling within the receiving area.

[0010] The longitudinal separating elements are in particular of elongated design. The longitudinal separating elements preferably extend at an angle to the transverse direction, in particular in the direction of rotation. Preferably, the device comprises a plurality of, in particular at least five, preferably at least ten, particularly preferably at least five, longitudinal separating elements, which are locally spaced apart from one another in the transverse direction. In particular, the longitudinal separating elements extend in the direction of rotation. Due to this number of longitudinal separating elements and the accommodation areas resulting from a correspondingly large number, these accommodation areas have a width in the conventional width of the device such that, viewed in the direction of rotation, only one, or at most several, root crops can be arranged side by side. The width of the device is in particular 0.3 m to 3 m, preferably 0.5 m to 2.5 m, preferably 0.9 m or 2.4 m.

[0011] Preferably, the local distance between the two longitudinal separating elements in the transverse direction is between 20 mm and 150 mm, particularly preferably between 30 mm and 80 mm, and most preferably between 40 mm and 60 mm. Due to the width of the intermediate receiving area corresponding to these dimensions, root crops that are adjacent to one another, as viewed in the direction of rotation, are prevented from being received in the receiving area to the greatest extent possible.

[0012] The transverse separating elements are particularly elongated. They preferably extend elongated in the transverse direction, that is, transversely to the direction of rotation. Alternatively, they preferably extend at an angle not only to the transverse direction but also to the direction of rotation, wherein the direction of extension of the transverse separating elements encloses an angle with the transverse direction that is less than 60°, preferably 45°. Preferably, the distance between the two transverse separating elements in the direction of rotation or perpendicular to their elongated extension is between 40 mm and 250 mm, particularly preferably between 70 mm and 130 mm, and optimally between 90 mm and 110 mm. The respective lengths of the accommodating areas defined by the two transverse separating elements, measured in the direction of rotation or transversely to the direction of extension, are such that accommodating root crops arranged side by side in the transverse direction within the same accommodating area is minimized. Preferably, each accommodating area is designed to precisely accommodate a single root crop of normal size, with the longitudinal axis of the root crop being oriented parallel to the direction of extension of the longitudinal separating elements, or alternatively, parallel to the direction of extension of the transverse separating elements, during operation.

[0013] In a preferred embodiment of the present invention, not only the extension direction of the transverse separating element but also the extension direction of the longitudinal separating element are oriented at an angle relative to the transverse direction on the one hand and relative to the direction of rotation on the other hand. In particular, the extension directions are angled with the same angular value, but with different positive and negative signs relative to the direction of rotation. Preferably, the two extension directions are oriented pivoted 30° to 60°, in particular 45°, relative to the direction of rotation. In a top view, the transverse separating element and the longitudinal separating element are configured in particular in a diamond pattern. By means of this configuration of the separating elements, in the upward direction of the device during operation, the root crops arranged in the receiving area can be automatically centered in the following way, that is, the root crops roll away from the separating elements that delimit the individual receiving areas in the direction of the deeper nodes under the action of gravity. In this way, a maximum distance between the root crops and an optimal visibility of defective areas can be achieved.

[0014] In this respect, the transverse and / or longitudinal separating elements extend in the indicated directions, since they preferably extend linearly in said directions when viewed from above. The indicated directions therefore represent the main extension directions of the respective separating elements, without the separating elements necessarily being designed continuously in the main extension direction. Extending at least partially substantially in the transverse direction means that the extension direction and the transverse direction enclose an angle of less than 90°.

[0015] In an advantageous embodiment of the present invention, at least one longitudinal separating element is designed to rotate together with the support device during operation. The longitudinal separating element is particularly connected to the support device in a force-fitting or form-fitting manner and rotates at the same rotational frequency as the support device during operation. For this purpose, the longitudinal separating element is particularly detachably connected to the support device, preferably via a screwing element, a latching element, or a clamping element. The longitudinal separating element is preferably guided by legs or eyelets and thereby supported on the support device.

[0016] The longitudinal separating elements are preferably formed integrally with the supporting device. In particular, the sides of the receiving area adjacent to the interior are formed by thinner sections of the conveyor belt, while the longitudinal separating elements are formed by adjacent, thicker sections of the same belt, which extend further outward from the interior. This minimizes relative movement between the supporting device and the longitudinal separating elements, which could cause the root crops within the thus formed receiving area to move.

[0017] Preferably, the support device and the longitudinal separation element are at least jointly formed by at least one profiled screen bar. The screen bar has a cross-section that is at least essentially constant along its center line and is, in particular, rotationally symmetrical about the center line. The center line has a non-straight path. In particular, the center line extends in a plane and / or has a shape that is repeated over the length of the screen bar, preferably a wave-shaped shape. At least one receiving area is preferably jointly formed by a plurality of such screen bars, and the longitudinal separation element is, in particular, constructed only by at least one screen bar. Due to this design, the present invention can be implemented with a particularly small number of components, which have long been reliably used in the field of root crop harvesting technology.

[0018] Preferably, at least one transverse separating element and / or at least one longitudinal separating element is at least jointly formed, in particular constructed, by a plurality of separating elements arranged along their (main) extension direction and extending outward in a side view. In particular, these separating elements are not directly connected to each other. Preferably, the distance between adjacent separating elements is greater than the extension of the separating elements in the transverse direction or in a direction at an angle relative to the transverse direction. Particularly preferably, the separating elements extend from the base of the separating element (by which the separating elements are arranged on another component) in a direction orthogonal to the side of the interior space to an upper, in particular blunt, end region. In this case, the separating elements are in particular designed to be rotationally symmetrical at least primarily about an axis of symmetry parallel to this orthogonal direction and / or are finger-shaped. In particular, the separating elements are made of plastic or rubber, in particular cast around metal, and / or are elastically deformable. The separating elements of the transverse separating element and the separating elements of the longitudinal separating element are in particular designed to be uniform. By constructing the separating element from these separating elements, protective operation of the root crops and the independence of the boundaries of the different receiving areas are ensured.

[0019] Preferably, adjacent separating elements are at most 40 mm, particularly preferably at most 30 mm, and optimally at most 20 mm away from one another. Preferably, adjacent separating elements are additionally or alternatively at least 5 mm, particularly preferably at least 10 mm, and optimally at least 15 mm away from one another. This distance creates an optimal compromise between protective operation of the root crops and the best possible separation of the receiving areas from one another.

[0020] Preferably, the transverse separating element comprises a transverse separating element extending in its (main) extension direction and / or in the transverse direction, the transverse separating element extending at least partially outside the interior space in the transverse direction and / or the separating element being arranged on the transverse separating element. The transverse separating element is in particular a preferably curved screen bar, on which the separating element is in particular arranged, the separating element having its separating element root.

[0021] The transverse separating element is particularly rigid, preferably made of spring steel. In particular, at least a plurality of separating elements are integrally formed with a screen bar covering or a screen bar attachment, which is pushed onto or fitted onto the transverse separating element. The transverse separating element allows for a direct separation action in the direction of rotation, particularly during the ascending device path, and / or provides a secure support for the separating elements.

[0022] Preferably, the separating element extends at least 15 mm, preferably at least 20 mm, particularly preferably at least 25 mm, preferably in a direction at right angles to the side of the interior space and in particular from the side of the interior space. These dimensions correspond to the height of the separating element from its separating element root to its end area facing away from the interior space. In particular, a free space of the same height is left between two adjacent separating elements. In particular, in the case of a device for transporting sugar beets, this height is at most 150 mm. This dimensioning of the separating element reliably ensures the separation of root crops placed directly on the carrying device and at the same time eliminates any obstruction to the desired distribution of the root crops on the different receiving areas when the root crops are delivered to the device, in particular eliminates the possibility that root crops lying flat on the carrying device in the second position extend beyond the separating element.

[0023] Preferably, the longitudinal separating part is composed of at least a longitudinal separating element, in particular only of a longitudinal separating element, which separates a plurality of accommodation areas adjacent in the direction of rotation. The longitudinal separating element has a greater extension in the direction of rotation than the accommodation areas separated by it. In particular, the longitudinal separating element is constructed so as to rotate around the entire supporting device and / or is fastened thereto or is constructed integrally therewith. Preferably, the longitudinal separating element is a belt, which in particular has a circular cross-section with a diameter of preferably 12 mm. Due to this construction, the longitudinal separating part is particularly robust in operation and protects the harvest.

[0024] Preferably, the receiving area is formed by at least one shaping element extending laterally outward from the interior space. The shaping element extends less than the transverse separating part and / or longitudinal separating part or its separating element at a right angle to the side of the interior space. Preferably, the shaping element extends laterally outward from the interior space by 5 mm to 20 mm, particularly preferably 10 mm to 15 mm. The shaping element is particularly cup-shaped. Alternatively, the at least one shaping element is finger-shaped and preferably constructed in the same manner as the separating element except for its extension or length and provides a support point for the root crops arranged in the receiving area. The shape of the receiving area is achieved by at least one shaping element, which prevents the root crops accommodated therein from rolling. For example, the shaping element and the separating element are constructed in the manner of the profile elements that are usually raised in a rake belt.

[0025] As viewed in the direction of rotation, the profiled element is preferably arranged eccentrically between two longitudinal separating parts that are adjacent in the transverse direction. In particular, no profiled element is arranged in the middle between the longitudinal separating parts, so that the root crops arranged in the receiving area can be placed directly on the support device in this zone. Preferably, at least one profiled element is arranged adjacent to both one of the two longitudinal separating parts and the other of the two longitudinal separating parts, so as to form a trough-shaped or basin-shaped cross-section of the receiving area as viewed in the direction of rotation. In particular, a plurality of profiled elements offset in the direction of rotation are arranged adjacent to the longitudinal separating parts. Preferably, a plurality of profiled elements, in particular arranged on the same support element, are arranged between the longitudinal separating parts and the center of the receiving area defined thereby, as viewed in the direction of rotation. These profiled elements preferably have a length that decreases with their distance from the nearest longitudinal separating part, so that a cross-section for protecting the root crops is formed by a greater number of support points.

[0026] Advantageously, in a further embodiment of the device according to the invention, the carrier device comprises a recess extending transversely to the sides of the interior space. The device is in particular a screen belt. This allows for effective separation of adulterants from the root crops during transport through the device.

[0027] Preferably, the supporting device is at least jointly constituted by a plurality of particularly rigid and relatively movable supporting elements. In particular, the supporting device has a plurality of slender screen bars extending in the transverse direction, which are arranged adjacent to and parallel to each other in the direction of rotation. These screen bars are preferably arranged with their ends on a lateral continuous support, such as a plastic belt or a rubber belt, which is used to roll the deflection roller over and can be driven during operation. In this structure and construction of the longitudinal separation part through the separation element, at least one, in particular exactly one, separation element is arranged on each screen bar. Possible forming elements are preferably also arranged directly on the screen bar. The outward-facing upper side of the screen bar in particular jointly constitutes the accommodating area. Preferably, the screen bar is arranged in the interior space and is adjacent to the interior space side.

[0028] Preferably, each two support elements, in particular screen bars, form a one-piece support element unit. The support elements are in particular constructed from glass-fiber-reinforced plastic. Alternatively, the support elements are designed as grid segments that are movable relative to one another, or the support device is designed as a rake belt, wherein the end region of the shortest rake element or profile element is preferably located within or in contact with the side surface of the interior space.

[0029] The support elements are here particularly fastened to at least two continuous supports by means of at least one, preferably two, fastening means, such as rivets or screws. The continuous supports extend in particular parallel to one another and / or are elastically and are at least substantially integrally and in particular uniformly constructed over at least a major portion of their circumference. The transverse separating member and / or longitudinal separating member extend at least partially in an area in at least one of the continuous supports, intersecting not only the continuous supports but also the transverse separating member or the longitudinal separating member as an imaginary auxiliary straight line at right angles to the side of the interior space. The auxiliary straight line is at right angles not only to the direction of rotation but also to the transverse direction. The transverse separating member and / or longitudinal separating member therefore extend in particular (until) passing through at least one of the continuous supports. At least a portion of the accommodating area preferably extends at least partially above the continuous support, so that the continuous support is arranged between a portion of the accommodating area and the interior space. The area of ​​the device that can be used for transportation is thereby particularly large.

[0030] Preferably, the auxiliary straight line intersects not only the continuous support but also at least one separating element. Particularly preferably, the auxiliary straight line also intersects at least the supporting element and / or the transverse separating element. The separating element is particularly arranged on the supporting element or the transverse separating element. Preferably, the separating element is arranged on the supporting element or the transverse separating element as a separating element made of plastic, in particular completely encapsulating the supporting element or the transverse separating element. Preferably, a further straight line parallel to the auxiliary straight line intersects the continuous support and at least one of the shaped elements or an adjacent receiving area. The receiving area is thus formed above and between the continuous supports.

[0031] Furthermore, the aforementioned object is achieved by a separating device comprising a device described above or below, a device frame, and at least two deflecting elements rotatably arranged on the device frame. The separating device particularly comprises a drive, preferably one of the deflecting elements being designed as a drive element for transmitting torque. The deflecting elements are used to guide the device so that at least one conveying section of the device at least partially has an upslope. The device thus extends at least partially upward in the conveying section. Alternatively, the conveying section at least partially has a downslope, so that the device extends at least partially downward in the conveying section. In particular, the deflecting elements are deflecting rollers rotatably mounted on the device frame. This upslope or downslope facilitates the intentional arrangement of as few root crops as possible in each receiving area, because in the second position, the root crops in the receiving area roll or slide under the action of gravity in an adjacent, particularly subsequent, receiving area. As an alternative to the above-described embodiment of the conveying section, at least one conveying meander of the device for a special application of the separating device has an at least essentially horizontal course.

[0032] Preferably, a first conveying section of the device has a greater upslope or a greater downslope than a second conveying section following in the direction of rotation. In particular, the device passes through a deflection element between the two conveying sections during operation. The second conveying section extends in particular at least essentially horizontally. Having explained the advantages of the ascending direction of the device, the advantage of an adjacent less steep or horizontal direction is that, in this direction, the relative movement of the tubers in the receiving area with respect to the device is reduced. The less the tubers move on the device, the easier it is to control their descent. In this case, one conveying section or several conveying sections do not rotate with the device, but rather with a section fixed relative to the device frame, within which a consistent function, such as the calming of the movement of the tubers, is detected by the device.

[0033] The separating device preferably has at least one sliding element that does not rotate during operation and is arranged below at least one portion of the conveying section or one of the conveying sections. In particular, the sliding element is arranged below the second conveying section. Preferably, the sliding element is a slide rail on which the device slides during operation, in particular between two deflection elements, thereby preventing the device from sagging. Preferably, the separating device has a plurality of sliding elements that are spaced apart from one another in the transverse direction. The at least one sliding element prevents or at least reduces the onset of an impact on the root crops that could trigger their movement.

[0034] According to another technical solution of the present invention, the separating device has at least one impact element that is movable, in particular rotating, during operation. The impact element is used to generate an impact on at least a part of the conveying section or one of the conveying sections. In particular, the impact element is arranged below the first conveying section that rises during operation. During operation, the impact element generates a force pulse on the device, which is preferably not oriented in the direction of rotation. As a result, the device is shaken, in particular in the first conveying section, thereby generating a uniform distribution of root crops on the receiving area. Specifically, the impact element is preferably configured as an element with an eccentric outer contour that rotates during operation. Alternatively, and in particular in the case of a profiled underside of the device or in the case of a continuous support that runs on the impact element during operation, the impact element is configured as an element that rotates during operation and is at least essentially rotationally symmetrical, that is, preferably configured as a roller. The function of the at least one impact element during operation is especially automated. Preferably, during operation, at least one operating parameter of the impact element, in particular its rotational speed or its radius, depends on a user setting and / or data preferably originally recorded by at least one optical sensor on the device or on one of the machines described below, which data relate to the conveyed goods, in particular the proportion of foreign matter or root crops in the conveyed goods.

[0035] A scraping element is particularly arranged above the conveying section or one of the conveying sections, in particular the first conveying section, which is at most 20 cm, preferably at most 15 cm, from the side of the interior space and whose circumference is particularly adjacent to the profile element in a side view during operation. Particularly preferably, the scraping element is rotatably supported around an axis of rotation, which is particularly oriented parallel to the transverse direction. Preferably, the scraping element is preferably an elastically deformable roller, in particular made of foam material. Alternatively, the scraping element is configured as a retaining rubber or a brush. The scraping element serves to retain the root crops placed on the supporting element or rolled back in the second position along or against the direction of rotation and transfer them to a subsequent free receiving area.

[0036] Furthermore, this object is achieved by a mobile root crop harvester having the aforementioned separating device. This object is also achieved by a mobile or stationary transport or cleaning machine having the aforementioned separating device. A supply device for applying the root crops to the device is preferably arranged above the first conveying section. Furthermore, the separating device preferably comprises a drop-off stage with a conveying device following the device in the direction of the goods flow, on which the separating device is preferably arranged. The separating device preferably comprises a plurality of diverting elements arranged transversely offset, the diverting elements corresponding at least to the number of storage areas arranged sequentially in the transverse direction. The diverting elements are movable from a diverting position to an initial position and back again. In the diverting position, the diverting elements divert root crops discharged from the associated storage areas so that the root crops do not reach the subsequent conveying device. In the initial position, the diverting elements are arranged outside the goods flow. The diverting elements are actuated, in particular, based on information from at least one sensor, in particular a camera, arranged on the (second) conveying section, which optically detects the root crops or foreign objects to be diverted.

[0061] The features explained below according to exemplary embodiments of the present invention may also be used alone or in combinations different from the illustrated or described subject matter of the present invention. Components with the same function are provided with the same reference numerals whenever this is appropriate.

[0062] The illustrated embodiment of the device 2 according to the invention is a multi-part conveyor belt for conveying root crops. Figure 1 、 2 , 5, 6, 9 and 10 each show only a section of the corresponding embodiment, which is shown as extending substantially flat. The end shown can be coupled to the opposite end (not shown) to form a closed, rotating belt. These embodiments include a support device 7 that rotates in the direction of rotation 8 during operation. The support device includes a plurality of support elements 6 (see FIG. Figure 4a 、 4b , 8, 12a and 12b). The carrying devices 7 together form a plurality of receiving areas 18, which are arranged offset relative to one another in the rotation direction 8 and / or in the transverse direction 12. The carrying devices 7 are configured to carry root crops.

[0063] The device 2 comprises a plurality of transverse separating elements 14 extending in the transverse direction 12, which separate adjacent receiving areas 18 from one another in the pivoting direction 8. The transverse separating elements 14 are used to prevent root crops placed in the receiving areas 18 on the carrier device 7 from escaping from the receiving areas 18.

[0064] The receiving area 18 adjoins the interior 11 from the outside, which extends within an imaginary interior side 10. The interior side 10 is parallel to the transverse direction 12 (see Figure 4a 、 Figure 8 and Figure 12a ) extends and, in a side view, extends only in the direction of rotation 8. In particular, the lowest part of the receiving area 18 formed by the supporting device 7 stirs the interior side 10 or the interior 11.

[0065] The side sections of the interior space corresponding to the illustrated device sections are flat. Figure 1 、 2, 3, 4b, 5, 6, 7, 9, 10, 11 and 12b, the interior space 11 of the device 2 partially shown in each case extends primarily behind the carrier element 6 shown. Figure 2 、 6 , 10, the receiving area 18 is substantially rectangular (see also Figure 3 、 7 , 11).

[0066] At least one raised portion of the transverse separating element 14 is arranged outside the interior space 11 in a side view, that is, above the side surface 10 of the interior space when the root crops are transported. This relates to the separating element 13 in the first and third embodiments (see Figure 13a and Figure 13b ), in the second embodiment, it additionally involves a part of the transverse separation element 24 designed as a transverse strut (see Figure 8 ).

[0067] Three (first and third embodiments) or four (second embodiment) support elements 6 designed as screening bars are arranged between two adjacent transverse separating elements 14 in the direction of rotation 8. In the second embodiment, two support elements 6 following one another in the direction of rotation 8 are designed as one piece. The support elements 6 and the transverse separating elements 24 are laterally fastened to two consecutive supports 4 of the device 2.

[0068] The embodiment of the device 2 shown has a plurality of longitudinal partitioning elements 16 extending in the pivoting direction 8 at right angles to the transverse direction 12. These longitudinal partitioning elements are arranged outside the interior space 11. The longitudinal partitioning elements 16 separate two receiving areas 18 that are adjacent in the transverse direction 12 from each other. During operation, the longitudinal partitioning elements 16 pivot with the supporting device 7.

[0069] In the first and third embodiments of the present invention, both the transverse separating element 14 and the longitudinal separating element 16 are formed at least jointly by a plurality of separating elements 13, 15 arranged in the transverse direction 12 or in the direction of rotation 8 and extending outward in a side view. The longitudinal separating element 16 is formed solely by the separating element 15. The transverse separating element 14 is formed adjacent to the separating element 13 by a transverse separating element 24 extending parallel to the support element 6. In the region of its ends, the transverse separating element 14 is arranged on the continuous support 4. In the second embodiment of the present invention, the longitudinal separating element 16 is formed by a belt extending in the direction of rotation 8. In this embodiment, two separating elements are arranged between two adjacent longitudinal separating elements 16 of each transverse separating element 14; in other embodiments, a separating element is arranged between two adjacent longitudinal separating elements 16 of each transverse separating element 14. The separating elements have a height of at least 25 mm relative to the support element or the transverse separating element on which the separating element is arranged.

[0070] The third embodiment of the device 2 according to the invention has a pot-shaped receiving area 18 (see in particular FIG. 12 ). These receiving areas are formed by profiled elements 20 which are arranged in a manner similar to that of the embodiment of the invention. Figure 10 In the top view of FIG, the profiled elements 20 are arranged in the receiving area 18 on the support device 7 and extend outward from the interior side 10, but not further than the surrounding separating elements. As seen in the direction of rotation, the profiled elements are each arranged eccentrically and adjacent to the two longitudinal separating parts 16 that delimit the respective receiving area 18. In particular, two profiled elements 20 are arranged on each support element 6 for each receiving area 18.

[0071] The device 2 according to the invention is based on Figures 16 to 18 The fourth embodiment is largely identical to the first embodiment. Unlike the first embodiment, it has receiving areas 18 that extend primarily above one of the continuous supports 4. For its construction, the fourth embodiment also has separating elements 13, 15 above the continuous supports 4, through which transverse separating elements 14 extend above the continuous supports 4, and through which each longitudinal separating element 16 extends completely above the continuous supports 4 and along the outer edge of the device 2. Figure 19a and Figure 19b A separating element 15 is shown which is also arranged at the end of the carrier element 6 for this purpose.

[0072] Figure 14A separating device 30 is shown, which includes a device 2. The separating device 30 has a rigid device frame (not shown) that does not rotate with the device during operation, and a plurality of deflecting elements 22 for guiding the device 2. The separating device 30 is configured with a first conveying section 26 and a second conveying section 28. In the first conveying section 26, the device 2 has an upward slope, while the second conveying section 28, which is connected in the direction of rotation 8, extends horizontally. Below the second conveying section 28 is arranged at least one sliding element 32, on which the device 2 slides in the second conveying section 28. Below the first conveying section 26 is arranged at least one impact element 34, which rotates during operation and is used to generate an impact on the device 2 in the first conveying section. Both the sliding element 32 and the impact element 34 are arranged in the interior space 11. A scraping element 36, which is rotatable during operation and is designed to be elastically flexible during operation, is arranged above the first conveying section 26. On the drop level for root crops, which follows the device 2 in the direction of flow of the goods, a separating device 44 is particularly arranged, which has individually controllable diverting elements 42 arranged in the transverse direction 12, the number of which corresponds at least to the number of receiving areas 18 arranged side by side with each other in the transverse direction 12.

[0073] The deflection element 42 is actuated as a function of information from an optical sensor 46 arranged above the second conveying section 28 , which optically detects root crops or foreign objects to be deflected.
