Description

[0001] Separating device for fruits, in particular for root crops, and separating arrangement

[0002] The present invention relates to a separating device for fruit, in particular for root crops, preferably for potatoes, with which the material to be separated is to be separated from a material flow comprising fruit and material to be separated, in particular in the form of leaves, with at least one conveyor device forming a conveying path over which at least part of the material flow runs during operation, and with at least one blower arrangement comprising at least one blower and at least one nozzle arrangement connected to the blower, the at least one nozzle of which is aligned with the conveying path. Furthermore, the invention relates to a separating arrangement comprising such a separating device and a further component.

[0003] DE 10 2012 016 057 A1 discloses a device of this type in which lighter material to be separated, particularly haulms or light soil, is blown into a hood. Due to the turbulence of the air streams and the steeply rising bottom sections of this hood, the material to be separated can accumulate in the hood and fall back onto the conveyor line.

[0004] Furthermore, DE 19 813 647 A1 discloses arranging a haulm separator above a conveyor line. The haulm separator has two intake rollers running transversely to the conveying direction, which draw the haulm between them. Above this pair of rollers, a flail roller grasps the haulm transported by the roller pairs, chops it up, and transports it further. The rotating flail roller creates a certain suction on the haulm, which promotes further transport and a correct transfer from the roller pair toward the flail roller. However, if the haulm does not reach the intake area of ​​the rollers, it continues to be transported along the conveyor line, which is undesirable.

[0005] The object of the present invention is to improve a generic device with regard to the disadvantages mentioned and, in particular, to remove light material to be separated, preferably in the form of weeds, from the material flow in an improved manner.

[0006] The object is achieved by an article according to claim 1 and by a separating arrangement according to claim 24. Advantageous embodiments of the invention can be found in the subclaims referring back to these claims and in the following description.

[0007] According to the invention, a generic separating device additionally comprises a suction device with a suction hood open toward the conveyor line and having a suction opening for extracting the separated material. In addition to the air coming from the nozzle, the suction device creates a suction force on the material flow, through which the haulm is extracted. The suction hood, with its suction opening and the suction effect generated therein, is directed particularly toward the area of ​​the conveyor line on which the nozzle of the nozzle arrangement acts, without any additional separating elements being arranged between the suction hood and the conveyor line.

[0008] The nozzle loosens the material transported along the conveyor line, with lighter components such as haulms being drawn upwards. The additional suction effect of the suction device then effectively transfers the haulms located in the upper section of the conveyor line into the suction hood, separating them from the rest of the material flow.

[0009] The extraction opening of the extraction hood is open toward the conveyor line in such a way that the suction effect of the extraction hood can capture the material to be separated in the material flow. In particular, the extraction opening is aligned with its planar extension at least approximately, i.e., within a surface angle of + / - 20°, between the opening of the extraction hood and the conveyor line defined, for example, by a conveying plane such as a surface or the envelope of a roller table.

[0010] In the case of drop stages in which the conveying section takes a curved course, the suction opening is designed in particular with its surface parallel to a tangent to the main conveying direction and the course of the conveying section.

[0011] The conveyor path is generally limited at the bottom by one or more conveyor elements, whereby the focus here is on the transport of the fruit and not on any quantities of soil removed by the separating device. For the purposes of the present invention, a roller separator, e.g., a roller table with a plurality of rollers, is a conveyor path extending above the rollers along a wrapper on the rollers, regardless of the fact that fruit may also be partially located between the rollers.

[0012] The nozzle assembly is connected to the blower in such a way that an air flow is created from the blower to the nozzle. This air flow is preferably achieved via supply air pipes, hoses, or similar hollow bodies. The nozzles preferably have an air outlet angle of 45° to the horizontal surface, viewed from the side.

[0013] In particular, the separating device comprises a machine frame or device frame for transport, for example, equipped with wheels, which is particularly provided with a receiving hopper into which the crop can be transferred. A feed conveyor belt can convey the crop from such a receiving hopper to the conveyor device or even be part of the conveyor device itself.

[0014] By dual processing of the crop flow, on the one hand via compressed air and on the other hand with a suction effect, the light haulms contained in the crop flow can be sucked away very effectively. For this purpose, the nozzle can be arranged either at the same height in relation to the conveyor line or in front of the extraction hood. In particular, the nozzle is directed towards an extraction opening of the extraction hood, in particular in such a way that the emitted air - at least in the case without a crop flow - enters the extraction hood for the most part or almost entirely (i.e. at least 80%), with the nozzle advantageously being arranged on one side of the crop flow and the extraction hood on the other side of the crop flow and thus of the conveyor line. In this way, the crop flow can be pressurised with air and processed using the suction effect of the extraction hood at the same time, which removes any existing haulms and any other light particles particularly effectively.The at least one nozzle and the one or at least one suction hood thus act in the same area of ​​the conveyor line.

[0015] According to an advantageous development of the invention, the extraction opening has a square design with four edges. However, the extraction opening can also be oval, in which case, in particular, tangents running parallel to the substrate on the long sides define parts of the floor and ceiling of the extraction hood, and tangents aligned perpendicular to these on the narrow sides define parts of the side walls. The extraction opening can have lateral air deflection elements that serve to reduce the amount of ambient air that does not originate from the nozzle.

[0016] A targeted transfer of the haulm into the extraction hood and into the area of ​​​​the extraction effect is achieved when the nozzle is directed towards an inner surface of a floor or ceiling of the extraction hood. An orientation towards the floor or ceiling is understood in particular to mean an orientation in which at least a large part of the air flow exiting the nozzle (considered without a crop flow) impinges on the corresponding area of ​​the extraction hood. Such impingement preferably occurs at an angle of 0° - 90° and in particular at an angle between > 0° and 45%, so that an almost parallel, tangential supply of air from the nozzle is also included.

[0017] A particularly advantageous variant of the invention is one in which the surface of the floor or ceiling of the extraction hood, i.e. its upper or lower inner side, is convex to form a Coandè flow. This is based on a side view of the extraction hood, in which the air flow from the nozzle goes from the opening of the extraction hood to its rear end, at which the air flow leaves the extraction hood. A Coandè flow is achieved in particular in combination with one or more appropriately aligned air flows from one or more nozzles. Due to the surface profile, the air flow clings to the surface and does not detach, so that a laminar flow is achieved, which removes the haulm particularly effectively from the conveyor line for the fruit. Ball formation in the extraction hood is avoided.

[0018] The design of a convex surface, i.e., without any angled surfaces, is also advantageous in cases where the airflow is not directed precisely toward the ceiling or floor, as the elimination of sharp transitions (as seen from the side) prevents turbulence in the extraction hood. Positioning the extraction hood above the conveyor line prevents stones and other heavier debris from entering the extraction hood. These can be more effectively removed downwards by gravity via screen belts, rollers, or similar separators.

[0019] In particular, the suction device or the separation device is provided with a flap-like, i.e. movable, air guide element with which the suction opening can be closed and which can be actuated in particular via an actuating means coupled to the control device of the conveying device. Preferably, the air guide element is pivotally mounted on a front edge of the ceiling or floor. Such an air guide element is particularly advantageous for variants of the invention in which, by means of a cleaning program, any rollers or belts can be set into high-speed operation in order to loosen adhering impurities. These cannot get into the suction hood closed by the air guide element. Preferably, cleaning initiated by the control device is also accompanied by actuation of the actuating means both with regard to closing and opening the suction opening.Furthermore, the air guide element can be used to reduce the supply of ambient air when open. The flap-like air guide element preferably extends across the width of the opening, which is in particular completely covered in the closed position. In addition to the flap-like air element, lateral air guide elements can be arranged in front of the actual extraction opening. However, the air guide elements can also form the extraction opening, so that this is then formed by the edges of the air guide elements and, if appropriate, a base of the extraction hood.

[0020] To ensure optimal transport of the extracted haulm, the suction channel formed by the suction hood initially slopes upwards and then runs horizontally to the ground at least in certain points or sections (as viewed from the side). This largely prevents haulm accumulation in an area of ​​the suction hood that is still sloped downwards and slopes downwards, thus minimizing the risk of haulm falling back onto the conveyor line.

[0021] Preferably, the nozzle is arranged below the conveyor line when viewed from the side, while the extraction hood is advantageously located above the conveyor line. The extraction hood is arranged above the conveyor line in particular when, viewed from the side, the conveyor line runs beneath it regardless of any drop steps, and one end of a drop step is arranged below the conveyor opening.

[0022] For the purpose of improved supply of air to the conveying section, a nozzle tube of the at least one nozzle has a cross-section that varies and in particular becomes smaller along the width (of the conveying section), so that with a nozzle opening or outlet opening extending across the width of the nozzle, almost identical or at least sufficiently similar air velocities result. The nozzle is viewed in the longitudinal direction of the separating device or conveying direction. Preferably, the nozzle arrangement is provided with a further nozzle tube with at least one further nozzle, wherein the nozzle tubes each have cross-sections that decrease from the sides of the conveying section towards a straight line that is perpendicular to the conveying section and runs through its center, so that sufficiently similar amounts of compressed air are delivered from both sides of the conveying section (viewed in the conveying direction).

[0023] In particular, viewed in the conveying direction of the material flow, the at least one nozzle has at least one air outlet direction that is angled towards a straight line that is perpendicular to the conveying path and runs through its center. Such an air outlet direction can be achieved through the shape of the nozzle opening, through side walls or webs of the nozzles, or through cross-sectional tapering of the associated nozzle tube. By centering the air emerging from the nozzle during operation towards a central position above the conveying path, the haulm can be given a preferred direction. In particular, the haulm can be removed particularly effectively using an extraction hood that, viewed from above, has a narrowing width in the extraction direction and that tapers in a funnel shape, in particular.

[0024] The width of the suction opening advantageously extends across the width of the conveyor section, which is generally determined by the width of the conveyor elements when viewed in the direction of conveyance. In addition, according to a further advantageous embodiment of the invention, the nozzle can also be arranged next to the conveyor section, namely in a side view and particularly when the conveyor section is designed to be inclined or has a drop. Particularly with drop steps, sufficient space can be provided for the installation of a nozzle, or the freely falling weeds can be separated particularly effectively.

[0025] The conveying device and the blower arrangement are preferably movably mounted on a machine frame in order to be able to take into account any variations in the conveying path caused by movable conveying elements, for example when setting different distances and inclinations of a roller table.

[0026] A more compact variant of the invention is realized when the fan is arranged downstream of the extractor hood and upstream of the nozzle, i.e., the system operates with an air circuit, whereby any weeds can be filtered out of the air stream, for example, via a cyclone. Alternatively, the extraction device can have a separate extraction fan, which simplifies the air flow.

[0027] To adapt the extraction hood to changes in conveyor lines or variations in the associated conveyor elements, the extraction hood is preferably pivotably mounted on the device frame in the area of ​​the nozzle by means of a subframe. In particular, the extraction hood can be adjusted together with a part of the conveyor device arranged on the subframe, so that, for example, if the spacing of a roller separator changes as mentioned above, the position of the extraction hood can be varied accordingly.

[0028] To further optimize the alignment of the extraction hood and its extraction opening relative to the conveyor line, in a further embodiment of the invention, the extraction hood can be pivotally mounted on the subframe to allow the alignment of the opening relative to the conveyor line to be varied. The conveying device can advantageously comprise two conveying elements, in particular in the form of roller separators or roller tables and / or conveyor belts, between which the nozzle is arranged, so that the nozzle can act in or on the transition area between the two conveying elements. This applies in particular if the conveying elements form a drop step.

[0029] The conveying device preferably has at least one roller or cylinder table as a conveying element, in particular two successive cylinder tables with rollers mounted, for example, via a scissor mechanism and which can be moved at different distances from one another.

[0030] The object stated at the outset is also achieved by a separation arrangement comprising at least one separation device as described above or below and comprising a cyclone arranged downstream of the suction hood for removing the material to be separated from the air flow present during operation of the separation device.

[0031] In an advantageous development of the separating device or arrangement according to the invention, the suction fan is designed to chop the haulm. This facilitates any separation in the cyclone.

[0032] Furthermore, the separation arrangement comprises, in particular, at least one discharge conveyor belt, which is arranged downstream of the conveying device and, in a side view, is located below it. Such a discharge conveyor belt can be used to discharge, for example, fruit, in particular potatoes, or, when multiple discharge conveyor belts are used, waste products on the one hand and fruit on the other.

[0033] The separating device can be part of a harvesting machine. However, it can also be part of a stationary or mobile storage device.

[0045] Individual technical features of the exemplary embodiments described below can also be combined with previously described exemplary embodiments as well as the features of the independent claim and any further claims to form subject matter according to the invention. Where appropriate, elements that are at least partially functionally equivalent are provided with identical reference numerals.

[0046] A separating device 2 according to the invention has a conveyor line indicated by arrows 4, which in this case is formed by two roller separators 6 arranged one after the other in the form of roller tables. During operation, the material flow runs from a receiving hopper 22 via a feed conveyor belt 24 (see Figs. 1 and 2) to a first roller separator 6 located downstream of the receiving hopper 22, which forms a drop stage with the second roller separator 6 located further down in Fig. 1. Two blowers 8 arranged laterally along the conveyor line (viewed in the conveying direction F of the fruit) compress ambient air and guide it via supply air pipes 9 to a nozzle arrangement 10 (Fig. 3). The nozzle arrangement 10 comprises two nozzle pipes 13 with nozzles 12 arranged at their upper ends (Figs. 3 and 4). These nozzles 12 are arranged below or diagonally below the conveyor line and are directed toward the material flow passing the drop stage. The upper parts of the suction hood 18 are shown in Fig.3 not shown for clarity.

[0047] The respective nozzle tubes 13 taper continuously from the respective inlet side according to the section shown in Fig. 5, so that the air flow remains at least approximately the same across the entire width of the outlet opening of the nozzles 12. The openings of the nozzles 12 extend across the entire width of the respective nozzle edge 17 (Fig. 5). Due to the tapered cross-section and the opening across the entire width, the air outlet directions indicated by dash-dotted arrows 19 result, which are angled towards a straight line 21 perpendicular to the conveyor line and running through its center (Fig. 3). The weed to be separated thus already receives a preferred direction towards an outlet 23 of a suction hood 18 arranged above the conveyor line. In general, the angle of the air outlet direction with the straight line 21 becomes smaller towards the center. The suction opening 16 (cf. Fig.6) the suction hood 18 is open towards the conveyor line, in particular in such a way that a surface normal of the surface describing the suction opening 16 intersects the conveyor line.

[0048] The suction hood 18 with its suction opening 16 is part of a suction device 14 that extracts the haulm from the crop stream. For this purpose, a suction fan 35 is connected to the suction hood 18 via a suction pipe 25.

[0049] Depending on the distance between the rollers 27 of the roller separator 6, larger or smaller clods, pieces of soil, and stones fall onto the discharge conveyor belts 26. Another discharge conveyor belt 28 serves to transport the crop. The separating agents (nozzle and suction hood) acting on the conveyor line or crop flow from above and below, in conjunction with the two roller tables or roller separators 6, ensure optimal separation of the harvested crop.

[0050] To ensure that as little ambient air as possible can flow into the extraction opening, it is connected to a controllable, flap-like air guide element 30, which also has a rubber lip 32 at its lower end. For optimal separation of the herb, the nozzle is directed toward the extraction opening of the extraction hood in such a way that the air flow strikes an inner surface 34 of a base 36 of the extraction hood 18. It is understood that the air flow does not completely strike this surface 34, but at least a large portion, in particular 50%, does (Fig. 6).

[0051] The air flow, indicated by dash-dotted arrows 38, is guided along the curved surface 34 in the preferred direction along the inner surface 34 of the base 36, utilizing the Coanda effect. Since the air flow extends along the lower surface 34, detachment of the air flow is largely prevented, so that the haulm is guided further along this surface 34 toward the extraction fan 35. This controlled entrainment of the haulm at least partially prevents the haulm from bouncing off, particularly from the ceiling 40 of the extraction hood 18. In the extraction fan 35 of the extraction device 14, the haulm can be further reduced in size before being transported further with the exhaust air flow, for example, toward a cyclone 43 (Figs. 10 and 11).

[0052] The flap-like air guide element 30 is pivotally mounted on the ceiling 40 of the extraction hood 18 via an actuating means 44 at its upper end. The air guide element 30 can close the extraction opening 16, which is particularly advantageous when a cleaning signal is sent to the rollers 27 via a control device 42. For this purpose, the rollers can switch to a high-speed mode, via which any adhering debris is removed. To prevent this from entering the extraction hood 18, the control device 42 simultaneously sends an actuation signal to close the extraction opening 16. After the high-speed mode has ended, the control device 42 can then again send a signal to the actuating means 44 to open the flap.

[0053] The arrangement of the suction hood 18 above the conveyor line and the convex design of the base 36 mean that the suction hood 18 has a suction channel 46 which, in the side view, for example, in Figs. 6 to 9, initially rises and then runs horizontally to the base 41 at least in certain points or sections. This also helps to prevent the suctioned weeds from accumulating and falling back.

[0054] By angled air outlet directions toward the straight line 21, the weed is given a preferred direction, which prevents collision of the weed with the side walls 48 of the extraction hood 18, which narrows in the extraction direction and is funnel-shaped in plan view. For the purpose of better identifying the air flow and the associated direction, both the cover 40 and the air guide element 30 have been omitted in Fig. 3.

[0055] The suction opening 16 extends across the entire width of the conveyor line, i.e., across the width of the rollers 27 intended for transporting the material. Due to the arrangement and alignment of the nozzle 12 with respect to the drop step (Figs. 6 to 9), the nozzle 12 is also arranged next to the conveyor line in the side view of Fig. 6. The nozzle 12 itself has a right-hand side section in Fig. 4 that is drawn inward in order to optimally adapt to the adjacent roller 27 and thus to optimally utilize the installation space.

[0056] The conveying device and the blower assembly are movably mounted on a machine frame 50, so that the nozzle 12 can be moved when the spacing of the rollers 27 changes. The separate extraction fan 35, together with the extraction hood 18, is pivotally mounted on a subframe 52 at one end via a bearing 54 on the machine frame 50. The other end of the subframe 52 is mounted on the frame 50 by means of an adjusting means 56. The second roller separator 6 is connected to the subframe 52 in such a way that a change in the spacing of the roller separator 6 is accompanied by a change in the mounting of the extraction device (see Figs. 7 and 8). Due to the coupled movement, the extraction hood 18 remains in the optimal position relative to the nozzle 12.

[0057] In addition, by actuating a hood actuating means 59, the suction hood 18 can be optimally aligned to take into account, for example, different floor conditions (Fig. 9).

[0058] A separating device arrangement according to the invention according to Figs. 10 and 11 additionally comprises a cyclone 43 for separating the extracted weeds. While in this exemplary embodiment only one blower 8 according to the variant according to Fig. 11 is present, which thus operates in a circulating system both for supplying the air to the nozzle 12 and for extracting the weeds, according to Fig. 10 a further extraction blower 35 is used for extraction. In this case, the air exiting from an extraction pipe 60 does not need to be directed back towards the nozzle 12. The supply air pipes 9 shown in Fig. 11 are thus indirectly supplied with compressed air from the blower 8 via the cyclone 43. Nevertheless, even with an air circuit, several blowers can of course be used to accelerate the air flow.
