    TRANSPORT DEVICE FOR TRANSPORTING
    GROOVED CHOPPERS This invention relates to a transport device for transporting harvested root vegetables, comprising at least two carrier belts arranged approximately parallel at a distance from each other and several insert elements which can be arranged between the carrier belts for transporting the harvested root vegetables. The carrier belts of such a transport device can take several forms here. These carrying straps can specifically take the form of straps, but they can just as well be designed as straps, chains or the like. In addition, this invention relates to a harvester for harvesting root vegetables, comprising such a transport device.
    More specifically, this invention relates to a potato harvester. However, a harvester according to this invention can also find application for harvesting other root vegetables such as, for example, tubers or roots, etc.
    Such harvesters can vary from machines pulled by a tractor or carried on a tractor to self-driving vehicles.
    In such a harvester, transport and / or cleaning devices are arranged for transporting the root vegetables and in the meantime sieving dirt from the harvested root vegetables. Dirt to be sieved typically comprises leaves, stones, earth residues, etc. The root vegetables can be taken to a storage bunker, which can form part of the harvester, or can be placed on a wagon that rides next to the harvester. Alternatively, these root vegetables can be transported by means of the transport and / or cleaning devices to a big-bag or a crate or a bag or be deposited on the ground.
    The conveyor device from such a harvester to which this invention relates can also have a sieve function for sieving leaves, stones, earth residues, etc.
    Such a harvester can comprise two types of conveyor devices with parallel carrier belts and parallel transverse elements.
    A first type of conveying device comprises a so-called sieve belt, which is typically arranged in the harvester at the beginning of the conveying path for sieving leaves, stones, earth residues, etc.
    Such a sieve belt can also be positioned further along the transport path.
    Such a sieve belt is typically made up of parallel carrier belts to which spaced-apart cross bars are riveted.
    These transverse rods can be designed, for example, as metal rods, which are coated, for example, with plastic.
    There are sieve openings between the cross bars.
    A first problem with such sieve belts is that such conveying devices are heavy and determine a large part of the weight of the harvester.
    An additional problem is that, since the transverse bars are riveted to the carrier belts, the sieve openings cannot be readily adapted to, for example, the varying dimensions of the root crops to be harvested or to the varying soil conditions.
    An additional problem is that the sieve belt comprises carrier belts and drive wheels which may depend on the sieve openings.
    If a different sieve opening is desired, not only the sieve belt including its carrying belts must be replaced, but also the associated drive wheels.
    Moreover, the manufacture or repair of such a transport device is a rather laborious work.
    A second type of transport device is an elevator.
    Such an elevator does not always include a sieve function.
    A ring elevator, for example, does not have a sieve function.
    An example of such a transport device, which can be designed as a normal elevator or as a ring elevator, is known, for example, from EP 2 420 125 B1. The transport device from EP 2 420 125 B1 comprises a transport member which is provided with several in each case at least one driver and at least one laying surface defining one-piece structural bodies which are provided with screen perforations. These structural bodies are each attached to transverse bars which are riveted at an intermediate distance from each other to two parallel carrier bands. In view of the fact that the structural bodies are made of plastic, such a transport device can be of much lighter design than the above-described sieve belts. In order to be able to attach the structural bodies, however, the structural bodies have been elaborated in a complex way with a relief structure. With every two adjacent structural bodies, a fastening rod has to be woven through openings of one of the two structural bodies and woven through openings of the other of both structural bodies, which is very cumbersome. It is equally time-consuming to repair the transport device in the event of a defect in the structural bodies. Also with these structural bodies it is not easy to adapt the size of any sieve openings to, for example, the dimensions of the root crops to be harvested or varying soil conditions.
    Another type of elevator, without a screen function, comprises four parallel carrier belts, parallel transverse elements attached to these carrier belts and flexible inserts attached to the transverse elements. The carrier belts follow such a path that in part of the path the insert elements form baskets for transporting the root vegetables and are stretched out in part of the path where no root vegetables are to be transported in order to save space. These insert elements are made of plastic so that this transport device is also lighter. The transverse bars are arranged through a loop on the edge of the insert elements and are riveted to the carrier straps, which is also disadvantageous here for the recovery of the transport device.
    The present invention further relates to a mobile cleaning installation for cleaning harvested root vegetables, which comprises such a transport device. In such a cleaning installation, a conveying device according to the invention will typically also perform a screening function. This transport device can be constructed in an analogous manner to the listed transport device for harvesters and then has the same drawbacks.
    The object of this invention is to provide an alternative conveying device according to the preamble of the first claim, which can be of lighter design than the known mesh belts and which is simpler to manufacture or repair.
    This object is achieved by providing a transport device for transporting harvested root vegetables, comprising at least two carrier belts disposed substantially parallel at a distance from each other, and a plurality of insert elements, which can be arranged between the carrier belts for transporting harvested root vegetables, each insert element comprises clip elements at two opposite edges, which extend transversely to the carrying straps, for releasably receiving the insert element in the transport device by means of snap connections. The insert elements can be mutually clickable at these opposite edges and / or can be clicked into attachment transverse elements. Preferably, such a transport device comprises a plurality of substantially parallel securing transverse elements, which are attached at an intermediate distance from each other between the carrier straps, preferably to these carrier straps. Each insert element can then preferably be attached to at least one corresponding fastening cross element by means of the snap elements. The insert elements will be clickable on at least one of the above-mentioned edge to one of the securing transverse elements. At the opposite edge these insert elements can either be clickable to a second said transverse element, which also serves as a securing cross element, or be detachably attachable to an adjacent insert element, for example with the aid of a similar snap connection. Between the two said edges, the insert elements can optionally be clickable to additional securing transverse elements. In addition, the inserts can also be clipped laterally to the carrying straps.
    Preferably, the insert elements can only be releasably fastened in the transport device with the aid of said click connections. By working with insert elements which can be releasably received in the transport device by means of click elements, such a transport device can be made much lighter and cheaper than the existing sieve belts, given that fewer or even no parallel transverse elements are required to realize such a transport device. and given that inserts can typically be of lighter design. As a result, such a transport device can typically also be stored more easily in embodiments in which the insert elements take up limited space. The inserts can also be stored separately. This also makes it easier to store the carrying straps with any transverse elements.
    By providing the insert elements in a clickable manner on securing transverse elements and / or the carrier belts, such a transport device can be manufactured much more simply than the known transport devices for harvesters of root vegetables. This device no longer requires additional fastening elements, such as fastening bars, to be placed through fastening elements and / or openings of the inserts.
    The inserts can also be easily detached individually to, for example, replace them in the event of a defect or to provide access to other parts of the harvester for cleaning or repair, or to, for example, interchange inserts with deviating perforations in order to adapt the transport device accordingly. the varying dimensions of the root crops to be harvested as well as the varying soil conditions. This makes the transport device more maintenance-friendly. Since the insert elements can be detached separately, the carrier belts and the drive wheels of the sieve belt are no longer dependent on the sieve openings.
    Rods and / or battens and / or profiles and / or pipes can be used as the aforementioned securing transverse elements. Preferably cross bars are used, which are riveted, as this provides a strong connection. Since the insert elements are now attached by means of snap connections, this riveting of the attachment cross elements to carrier straps is no longer a drawback in itself.
    These securing transverse elements can be made of metal or of plastic. These can optionally be provided with a coating. Furthermore, these can also be provided with one or more extensions.
    A conveyor device according to this invention may include two said carrier belts, or may comprise more than two such carrier belts. These carrying straps are preferably made of rubber that is reinforced with fibers. These carrying straps can optionally be provided with cams.
    In a first specific embodiment, the click elements can comprise at least one click cavity, for locking a said corresponding securing cross element into this click cavity.
    At least one such click cavity is provided per corresponding securing cross element. Such a click cavity is then demarcated, for example, by means of one or more flexible click legs which can deflect elastically with respect to the click cavity in order to realize the click connections.
    In an alternative specific embodiment, the snap elements may comprise a plurality of snap fingers, and a plurality of snap perforations corresponding to these snap fingers, which are disposed at a certain distance from the corresponding edge, the insert element being pliable at this edge and wherein in the pleated state each snap finger is in the corresponding click perforation is clickable. In order to receive the insert element in the transport device, it can be folded at the said edge around a securing cross element, after which the click fingers are clicked into the corresponding click perforations. Alternatively, the click fingers can, for example, be folded through openings of an adjacent insert element and clicked into the corresponding click perforations.
    With such click fingers, the insert elements can be attached to the corresponding fastening cross elements in such a way that these insert elements are rotatable with respect to these fastening cross elements. This is particularly advantageous in conveying devices in which the insert elements have to take several shapes, such as, for example, in elevators in which these insert elements form baskets in a first zone and are stretched out in a second zone.
    Preferably, such click fingers are mainly of flexible design. The flexibility of such click fingers can be chosen in such a way that on the one hand these click fingers can be clicked loose again after locking them, when one click finger is pulled hard, but on the other hand when usual forces act on the insert elements, these forces are absorbed together by several click fingers, so that they do not come loose. Such customary forces are forces that typically occur when transporting root vegetables during harvesting and / or cleaning.
    Such a click perforation can take several forms. Preferably, it has a predominantly triangular design, so that a corresponding click finger can be easily attached here by means of a rotary movement.
    A said click finger is preferably provided with at least one hole, so that it can be grasped with a manual tool in order to more easily fix the click finger through the click perforation.
    A said click finger is furthermore preferably provided with a flexible widening, in order to hook with this widening behind a click edge of the corresponding click perforation, which delimits this click perforation.
    Furthermore, the click elements in such embodiments preferably comprise a plurality of through openings corresponding with the click fingers, which are arranged at a certain distance from this edge, for arranging the corresponding click finger through this through opening in the folded state before snapping this click finger into the corresponding click perforation. . These through-openings can either be located further from the corresponding edge than the click perforations, or - more preferably - be arranged between these click perforations and the corresponding edge.
    With such through openings, the click fingers are then arranged through at least two openings, namely the corresponding through opening and the corresponding click perforation, in order to realize the click connections. On the one hand, this ensures that these click fingers come off less quickly. On the other hand, the potatoes can suffer less damage due to protruding click fingers.
    In order to realize the snap elements, each insert element is preferably at least partially flexible, at least at the level of the snap elements.
    Each insert element preferably further comprises a supporting surface, which is provided for arranging the root vegetables thereon for the purpose of transporting these harvested root vegetables, this insert element being of flexible design at the level of this supporting surface.
    In a preferred embodiment, each insert element is of substantially flexible design. Vegetables are less likely to be damaged on such a flexible element, as a result of which the transport device is more product-friendly.
    Such a flexible element can also take other forms more simply, for instance to deform between a zone of the transport device in which this element takes the form of a basket and a zone of the transport device in which this element is extended.
    Furthermore, dirt adheres less well to such a flexible element, since dirt can come loose when this insert element is flexibly deformed.
    In order to prevent chop vegetables from falling between a flexible embodiment of an insert element and a carrier belt, this insert element can optionally be attached to this carrier belt, directly or with the aid of an intermediate piece.
    An insert element of a conveying device according to the present invention comprises a preferably substantially planar structure, which may optionally be provided with perforations. Such a flat structure is easier to realize than a relief structure.
    Furthermore, an insert element of a transport device according to the present invention with fastening cross elements, between said two opposite edges of this insert element, is substantially thinner than the corresponding size of the fastening cross elements.
    A special embodiment of a conveying device according to the present invention comprises a plurality of substantially parallel auxiliary transverse elements, which are attached at an intermediate distance from each other between the carrier belts, this preferably to these carrier belts. These auxiliary transverse elements are preferably arranged above or below a said insert element. By arranging the auxiliary transverse elements above or below the insert elements, such an insert element remains easily detachable, without these auxiliary transverse elements having to be detachable for this purpose. Such an auxiliary transverse element can, for example, be provided to make the conveyor belt formed therewith stronger or to ensure that it can twist less. It can also be provided, for example, to support the insert element. When the transport device is provided with a plurality of said attachment transverse elements, these auxiliary transverse elements are preferably arranged between the attachment transverse elements.
    A said auxiliary transverse element can optionally be attached to the insert element. To this end, the insert element can for instance comprise one or more hooking elements for hooking the insert element to this additional transverse element. Alternatively or additionally, such an insert element can comprise one or more additional snapping elements for snapping the insert element to this auxiliary transverse element. More specifically, a said hook element could also be designed as said additional click element. As an alternative, this auxiliary transverse element could be attached to the insert element, for example by means of a tensioning strap.
    Each insert element of a transport device according to the present invention can advantageously comprise one or more support elements, which, in the attached state of the insert element, rest on or on the carrier straps. These one or more support elements can more specifically be provided with further click elements, for snapping these one or more support elements to the carrier straps. Alternatively, these support elements can be provided for free movement relative to the carrier straps. In order to limit the number of transverse elements, two adjacent insert elements are preferably attachable to the same fixing transverse element. Corresponding snap elements of these adjacent insert elements are then preferably arranged alternately for this purpose. Preferably, each insert element of a conveying device according to the present invention is provided with teeth that can be arranged in grooves of an adjacent insert element, so that mating insert elements can engage with each other by means of a tongue and groove connection. The snap elements of such an insert element for attaching it to the corresponding fastening cross elements are then preferably provided on the teeth of this insert element, such that two adjacent insert elements can be fastened to the same fastening cross element. The teeth and grooves can then form part of alternately arranged snap elements of adjacent insert elements. A specific embodiment of a transport device according to the present invention comprises a carrier element which is provided with snap elements, with which the carrier element can be snapped onto a said transverse element connecting to a said insert element in order to form an upright edge relative to this insert element. Such an embodiment of a transport device can for instance be used as an elevator.
    The driver element of such an embodiment is preferably provided with teeth which can be arranged in grooves of an adjacent insert element and is preferably provided with grooves in which teeth of an adjacent insert element can be arranged, so that this driver element can be applied to this with the aid of a tongue and groove connection. adjacent insert. An insert element of a transport device according to the present invention is preferably made of plastic. A transport device can be made less heavy with plastic insert elements. Plastic makes it relatively easy to reconcile contradictory requirements, such as providing on the one hand with sufficiently strong click elements to be able to realize a secure click connection and, on the other hand, providing a click function in these click elements and possibly making the insert element flexible between the click elements. In particular, such an insert element can be manufactured, for example, from polyurethane. The inserts of a conveyor device according to this invention are preferably substantially rectangular in shape. These are preferably made as thin as possible and provided with a substantially flat top side and a substantially flat bottom side.
    Optionally, the edges of these insert elements can be locally thickened to make them strong to prevent wear.
    The insert elements can be provided with perforations, which, for example, take the form of screen perforations and / or to prevent contamination of the transport device itself and / or to make the insert elements lighter and / or to use less material and thus become cheaper. and / or to allow visibility through the inserts. These perforations can take all kinds of shapes, such as for instance substantially rectangular or square or oval or circular, etc. The shape and dimensions of these sieve perforations are preferably selected in function of the root vegetables to be harvested and the dirt to be sieved.
    If an insert element with screen perforations is also made flexible, this enhances the screen function of such an insert element.
    The object of the present invention is further also achieved by providing a harvester for harvesting root vegetables, which is provided with a conveying device according to the present invention.
    The object of this invention is also achieved by providing a mobile cleaning installation for cleaning root vegetables, which is provided with a transport device according to the present invention.
    This invention will now be explained in more detail with reference to the following detailed description of some conveying devices according to this invention.
    The purpose of this description is only to provide illustrative examples and to indicate further advantages and particularities of this invention, and thus cannot be construed as limiting the scope of the invention or the patent rights claimed in the claims.

    The figures show the parts relevant to the present invention of some conveying devices in order to show their operation as clearly as possible in the figures.
    Parts of such a transport device, such as for instance drive means, which are of little importance for the further explanation of these specific embodiments of a transport device and a harvester or a mobile cleaning installation according to the present invention, have been omitted from the figures.
    The general structure and further components of such conveying devices and harvesters are known.
    Alternatives to this are also conceivable.
    It is certainly clear to a skilled person how the depicted parts fit into a transport device and how this transport device in turn fits into a harvester or a mobile cleaning installation, how this harvester or cleaning installation can be further developed and how the further components of such a harvester or the cleaning installation to this transport device.
    The first and the second shown conveying devices each comprise three carrier belts (2) arranged parallel to each other. The third conveyor device shown comprises four carrier belts (2) arranged parallel to each other. Alternatively, these carrier belts (2) could also be replaced by, for example, carrier belts or carrier chains or similar carrier elements, which typically perform a supporting function in conveyor belts (1).
    Depending on the requirements, more or fewer such carrier belts (2) (or alternative carrier elements) can also be arranged substantially parallel to each other in a conveying device according to this invention.
    These stringers (2) are each riveted to transverse bars (4, 5) which extend between and substantially transversely of these stringers (2), as can be clearly seen in Figures 1, 5 and 14. These transverse bars (4, 5) ) could of course also be attached to these carrying straps (2) in other ways. Instead of bars (4, 5), alternative transverse elements (4), such as for instance slats and / or profiles and / or pipes, could also serve.
    Insert elements (3) are each attached to the transverse bars (4) for transporting harvested root vegetables, as can be seen in Figures 4, 7 and 12-14. An insert (3) from the conveyor belts (1) shown in Figures 4 and 7 is shown separately in Figures 2 and 3. Alternative embodiments of such insert (3) are shown in Figures 8-10. An insert element (3) of the elevator (1) shown in Figures 12-14 is shown separately in Figure 11. In the conveyor belt (1) of Figure 7, in addition to the insert elements (3), take-along elements (12) are also attached to the cross bars (4). A carrier element (12) from the conveyor belt of figure 7 is shown separately in figure 6. The carrier belts (2), cross bars (4, 5) and insert elements (3) together form a continuous sieve belt in figure 4.
    In figure 7 these slings (2), cross bars (4, 5) and inserts (3) together form an elevator.
    In Figures 12-14 these stringers (2), cross bars (4, 5) and inserts (3) form an alternative elevator.
    The insert elements (3) each have a support surface (8) for carrying harvested root vegetables.
    The inserts (3) shown are in each case substantially rectangular in shape and, spread over their bearing surface (8), may or may not be provided with sieve perforations (6), so that any dirt from the harvested root vegetables can be screened through them. In the embodiment of Figure 2, these screen perforations (6) are substantially rectangular in shape. In the embodiment of Figure 8, these screen perforations (6) are also substantially rectangular in shape, this rectangular shape being in each case longer than in the embodiment of Figure 2. In the embodiments of Figure 9, these screen perforations (6) have a substantially square shape and in In the embodiment of figure 10, these screen perforations (6) have a substantially round shape. The shape and dimensions of these sieve perforations (6) are preferably selected in function of the root vegetables to be harvested and the dirt to be sieved. In figure 11 mainly square perforations (6) are provided. If this insert (3) is used in a ring elevator, these perforations do not have a screen function, but are mainly there to save weight and to be able to see through these inserts (3).
    The inserts (3), distributed over their support surface (8), are each essentially flexible in design. This can be done, for example, by manufacturing it from a suitable plastic in suitable dimensions. The insert elements (3) from Figures 2-4 and 7-10 can for instance be manufactured from PU, for instance by pouring PU in liquid form into a mold and allowing it to set. The insert elements (3) from Figures 11-14 can for instance be lasered from a sheet of plastic. By making them substantially flexible spread over their bearing surface (8), the bearing surface (8) can deviate from the bearing belts (2) due to the impact of root crops under the weight of these root crops, so that the root vegetables suffer less damage. In the embodiment from figures 11-13 they can thereby also deform between a wide position (figures 12 and 13), in which they form baskets for transporting the root crops to be harvested, and a narrow position in which they are stretched.
    In order to be able to attach the insert elements (3) to the transverse bars (4), they are each provided with snap elements (7) on their corresponding longitudinal sides.
    In the embodiments in Figures 2-4 and 7-10, these snap elements (7) have a shape corresponding to the shape of the transverse bars (4) and include flexible legs (26) with which they can be clipped around the transverse bars (4).
    These flexible legs (26) define a click cavity (16) in which the transverse bars (4)
    recorded when clicked.
    In the embodiment of Figures 11-13, the snap elements (7) comprise a plurality of flexible snap fingers (17), which are disposed on two opposite edges (18) of the insert element (3), and a plurality of through openings (22) corresponding to these snap fingers (17). ) which are disposed at a first intermediate distance from these edges (18) and a plurality of click perforations (19) corresponding to these snap fingers (17), which are disposed at a second intermediate distance from these edges (18).
    The insert element (3), when mounted, is folded at these edges (18) around a corresponding fastening cross element (4), the snap fingers (17) being arranged through the corresponding through openings (22) and through the corresponding snap perforations (19), in order to to grip their widening (21) behind the edge (20) of these click perforations (19).
    The dimensions of the through openings (22) are larger than the corresponding dimensions of the click fingers (17), so that the click fingers (17) can be smoothly placed through these through openings (22).
    The widening (21) of each click finger (17) is made wider than the width of the corresponding click perforation (19), so that the click finger (17) can only be applied in an elastic state through the corresponding click perforation (19) and then with the widening. (21) behind the edge (20) of the click perforation (19).
    The click perforation (19) is mainly triangular in shape, so that the click finger (17) can be easily attached through this click perforation (19) via a rotary movement.
    This triangle is preferably substantially isosceles, with a base located closest to the corresponding edge (18) and a point located farthest from this corresponding edge (18).
    When one click finger (17) is pulled hard in mounted condition, it can be released again.
    Under the influence of forces that act on the insert element (3) during normal use, this click connection will not come loose. Each click finger (17) is preferably provided with a hole (27) (see Figure 11), so that it can be grasped with a manual tool to more easily secure the click finger (17) through the corresponding click perforation (19). After fitting the snap fingers (17), the free ends of these snap fingers (17) are preferably on the side of the inserts (3), away from said bearing surface (8), as can be seen in Figures 12 and 13 so that the root vegetables are not or less hindered or damaged.
    Alternative click elements (7) are of course conceivable. Between the longitudinal sides on which the said locking elements (7) are provided, the insert elements (3) shown in Figures 2-4 and 7-10 are each provided with additional locking elements (9) with which they can be clicked onto intermediate transverse bars (5) , which are arranged between the transverse bars (4), to which the inserts (3) are attached at their longitudinal sides. These additional click elements (9) are constructed in the same way as the previously mentioned click elements (7) and can be clicked into the intermediate transverse bars (5) in the same way. In this way, the inserts (3) are also supported between their longitudinal sides by transverse bars (5). Instead of these additional snap elements (9), for example, hook elements could also be provided with which the insert elements (3) could be hooked to these intermediate transverse bars (5) or the transverse bars (5) could be used without any connection for support under the insert elements (3). can be prepared. Depending on the application, these intermediate transverse bars (5) and / or the additional snap elements (9) can optionally also be omitted or several such intermediate transverse bars (5) and several corresponding additional snap elements (9) can be provided per insert element (3).
    In Figures 11-13, only one insert (3) is shown at a time. Further inserts (3) are seen in Figures 12 and 13, attached in a similar manner to top and bottom cross bars (4, 5). In the wide position, as shown in Figures 12 and 13, the insert elements (3) form baskets arranged one above the other for lifting the root crops to be harvested. In the narrow state, which is not shown, the root vegetables are released and the inserts (3) are returned without root vegetables to the point for loading further root vegetables. In this narrow state, the inserts (3) are extended and partially overlap each other. In this overlapped state, transverse bars (5) to which upper and lower inserts (3) are attached are arranged above and below the illustrated insert (3). Such an elevator can also comprise additional cross bars (5) to which no inserts (3) are attached.
    Different insert elements (3) can also be accommodated in a transport device (1) according to the invention, this for instance with different lengths to accommodate variations in chain lengths of the carrier belts (2).
    In the snapped-on state of the shown inserts (3), being snapped to the transverse bars (4, 5), these inserts (3) mainly extend between the stringers (2), as can be seen in Figures 4 and 7. It is desirable to have these insert elements (3) connect as closely as possible to these carrier belts (2) and any screening elements arranged between them, so that root vegetables cannot fall between the insert elements (3) and the carrier belts (2) and any screening elements.
    The inserts (3) as shown in Figures 2-4 and 7-10 are locally provided with recesses (25) at the level of the intermediate transverse bars (5), in order to provide space for the crush (23) and the penetration ( 24) of these cross bars (5).
    If desired, the insert elements (3) can also be provided with support elements on their transverse sides, with which they can rest on, on or against the carrying straps (2) or any screening elements in the locked position. If desired, these support elements could also be provided with click elements with which they can be clicked onto the carrying straps (2).
    The insert elements (3) from Figures 2-4 and 7-10 are also each provided with teeth (10) and corresponding grooves (11) on their longitudinal sides, so that two adjacent insert elements (3) can be connected to each other by means of a tooth. - and groove connection, as can be seen in figure 4.
