Definitions
- the present invention relates to a finger belt unit for an agricultural separating device which is intended for separating a root crop crop stream, wherein the finger belt unit is provided with at least one finger belt which has at least one longitudinal support which runs around during operation. Furthermore, the finger belt unit has a first and a second lateral row of sorting fingers which are arranged one after the other in the longitudinal direction and which, for operation in the separating device, extend downwards from above into an effective area in the direction of at least one conveyor belt, wherein at least some of the sorting fingers delimit a plurality of successive conveyor areas which are provided with a lateral inlet opening and which are delimited to the front and rear in relation to the longitudinal direction by at least two sorting fingers.
- the invention relates to a separating device for separating root crops from a root crop crop stream and to a root crop harvesting machine with such a separating device.
- the crop flow comprising stones, clods and potatoes is transported by means of conveying devices to a conveyor belt of the separating device.
- the sorting fingers of a finger belt of a finger belt unit act from above on the crop lying on the at least one conveyor belt, whereby clods are crushed and potatoes and Stones are transported differently and thus separately.
- part of the root crop harvest flow preferably the root crops, is transferred to a conveyor belt of the separator by means of the finger belt.
- Finger belt units are disclosed in WO 2018/069551 A1. It has been shown that a finger belt unit provided with the conveying areas disclosed in principle has insufficient separation performance under certain harvesting conditions. However, increasing the rotation speed of the finger belt can lead to excessive impact on the root crops and thus be counterproductive.
- a finger belt unit is characterized in that the conveying areas, which are delimited to the front and rear by preferably at least three sorting fingers, extend over at least 50% of the effective width of the finger belt, viewed in the longitudinal direction, with one side of the respective conveying area located to the side of the inlet opening being delimited by at least two sorting fingers.
- the conveying areas are thus at least 150 mm wide.
- the effective width of a finger belt is defined by the left outer side of the outermost sorting finger(s) on the left and the right outer side of the outermost sorting finger on the right of the same conveyor belt when viewed in the longitudinal direction and describes the width of the effective area in which the sorting fingers come into contact with the root crop crop flow.
- the longitudinal direction of the finger belt is the longitudinal direction in which the finger belt runs on its lower, effective side during operation.
- a significantly larger part of the root crop harvest flow arriving on the conveyor belt during operation can be transported through the inlet opening under the finger belt unit without the first row of sorting fingers in the direction of rotation of the conveyor belt having an effect on the crop flow.
- significantly larger quantities of the root crop harvest flow can be transferred in the direction of a conveyor belt of a separating device during operation.
- the conveying areas extend in the longitudinal direction over at least 75% of the width of the finger belt in order to make the conveying areas even larger.
- the conveying area is an area without fingers which is delimited by the sorting fingers in a bottom view of the finger belt, with a correspondingly larger distance between the sorting fingers which delimit the inlet opening on the side facing the incoming crop flow.
- the sorting fingers which delimit the conveying area are arranged at a distance from one another, and accordingly the conveying area is an area whose extent, in particular in the longitudinal direction, is greater than the distance between the sorting fingers which form the lateral boundaries.
- the conveying area is not an area with a continuous border; rather, the shape of the conveying area is defined by a line that directly connects the sorting fingers that represent the boundary, i.e. by the shortest route, and which also connects the sorting fingers that delimit the inlet opening by the shortest route.
- the line runs along the outer circumference of the sorting fingers that delimit the conveying area.
- the conveying area is considered at a height of the sorting fingers at which they affect the root crop crop flow.
- the unloaded state of the sorting fingers is considered, which are in a mounted and operational position, i.e. acting on the crop flow, preferably vertically from above to a lower conveyor belt.
- the conveyor areas move one after the other through the effective area, the height section in which the sorting fingers act on the root crop crop flow, by means of a rotating finger belt.
- the inlet opening is located on the side of the finger belt which, when mounted, is directed towards the incoming root crop stream.
- the side of the conveying area opposite the inlet opening is delimited by at least three sorting fingers, preferably the second row, so that the sorting area has a substantially square shape, i.e. regardless of the circumferences of the sorting fingers, which makes good use of the available area of the finger belt.
- the first and second rows are each outer lateral rows of the same finger belt, which leads to a further improved utilization of the width of the finger belt for the conveying areas.
- the sorting fingers of the first and second rows are arranged one behind the other when viewed in the longitudinal direction, which leads to a further improved utilization of the available area on the finger belt.
- the sorting fingers following one another when viewed in the longitudinal direction are also arranged offset from one another If the sorting fingers are arranged one behind the other, they are congruent in the effective area in the longitudinal direction with the same sorting finger width.
- a particularly advantageous embodiment of the invention is one in which the average distance between the sorting fingers of the first row in the longitudinal direction of the finger belt is greater than the average distance between the sorting fingers of the second row.
- the root crop crop flow can thus penetrate better into the conveying areas.
- the width of the inlet opening in a side view, transverse to the longitudinal and circumferential direction is at least four times the distance between the adjacent sorting fingers that delimit the conveying area on the side of the conveying area opposite the inlet opening.
- the rear side can, but does not have to, be formed by sorting fingers that are arranged directly one behind the other in the longitudinal direction. Rather, they can also be arranged offset from one another in the longitudinal direction.
- the inlet opening is thus designed to be large enough that a sufficient amount of the crop flow can be introduced into the conveying area.
- the first and second rows are the left and rightmost rows of the finger belt unit viewed in the longitudinal direction, which comprises one or two finger belts. It is also within the scope of the invention to form an inventive finger belt with conveying areas arranged one behind the other.
- a conventional finger belt in which, viewed in the longitudinal direction, the fingers of a row are arranged equidistantly one behind the other, as a finger belt unit.
- the first finger belt from the direction of the incoming crop flow is the one with conveying areas, while the finger belt behind it can be a conventional finger belt from the prior art or a finger belt provided with conveying areas described above or below.
- the finger belt is a rotating finger belt during operation, which can be driven via associated drive means, e.g. drive rollers or shafts, and can be deflected via any deflection means.
- the finger belt unit also comprises a frame in which the finger belt(s) are stretched.
- the conveying areas of a finger belt unit according to the invention are delimited in the longitudinal direction between the first and second rows to the front and rear by at least two and in particular by at least three further sorting fingers designed as intermediate fingers.
- the conveying area can be delimited to the front or rear by preferably up to 15 sorting fingers.
- the intermediate fingers that delimit a conveying area extend in front of and/or behind the conveying area, again viewed in the longitudinal direction, in a straight line.
- the intermediate fingers that delimit a conveying area at the front and rear and are arranged one behind the other in the longitudinal direction are at least approximately the same distance apart.
- a spacing of "at least approximately the same distance” means distances that vary by a maximum of 10%. This not only makes planning easier, but also construction, since, for example, a grid dimension can be used to arrange the sorting fingers both longitudinally and transversely.
- a finger belt unit is further characterized in that the at least one finger belt has a further longitudinal support which runs around during operation and the longitudinal supports are connected to one another via at least one intermediate support.
- the longitudinal support or supports are formed in particular by respective chain or belt belts which have sufficient flexibility and strength. Belts which are used in particular are those with a fabric insert.
- the longitudinal supports are then located lengthwise on the sides of the finger belt.
- the intermediate support connects the longitudinal supports to one another and preferably keeps them at a distance.
- the intermediate support(s) can also be sufficiently stable to attach the sorting fingers.
- the two, preferably lateral, longitudinal beams are connected to one another by a plurality of intermediate beams running transversely to the longitudinal direction.
- the intermediate beams can, for example, be designed as flatly extending Surface elements can be formed, the length viewed in the longitudinal direction being sufficiently short not to hinder the circulation required during operation.
- these are rod-shaped intermediate supports, which are constructed, for example, from metal or a composite material that is sufficiently strong for an arrangement.
- the sorting fingers are arranged on the at least one intermediate carrier.
- the surface provided by the intermediate carrier is used to arrange the sorting fingers.
- all sorting fingers can be arranged on the intermediate carriers, which in particular facilitates assembly by means of prefabricated intermediate carriers with sorting fingers.
- the sorting fingers that limit the conveying area to the front and back are arranged offset from one another in the longitudinal direction when viewed from the side, so that the sides that limit the conveying area to the front and back run diagonally when viewed from below. This results in increased adjustment options for the interaction with the root crop crop flow.
- At least one of the conveying areas extends from the inlet opening diagonally against the longitudinal direction and thus to the rear, which improves the flow of crop into the conveying area.
- the width of such a conveying area is transverse to its longitudinal direction, which is diagonal to the longitudinal direction of the finger band, between 100 mm and 400 mm.
- the assembly of a finger belt according to the invention is further improved according to an embodiment of the invention if fastening areas provided and/or used for fastening the sorting fingers are arranged in a grid dimension.
- a grid dimension i.e. at least approximately equal distances, e.g. between any intermediate supports and between the fastening areas for the sorting fingers on the intermediate supports
- the conveying areas are limited to the front and rear in particular by sorting fingers, the fastening areas of which are arranged directly next to one another when viewed in the longitudinal direction, i.e. without free fastening areas.
- the conveying areas are therefore always limited or formed by sorting fingers that are directly next to one another when viewed in the longitudinal direction. This is particularly independent of whether the sorting fingers arranged next to one another are attached to the same or adjacent intermediate supports.
- the sorting fingers are arranged on the at least one longitudinal beam. Another part of the sorting fingers can be arranged on the intermediate beams. If only one longitudinal beam is present, all of the sorting fingers can also be arranged on the longitudinal beam.
- the longitudinal beam is This refers to an elongated tension element that is endless during operation, runs around and is therefore sufficiently flexible.
- a finger belt unit comprises two finger belts running next to one another and rotating in the same direction, with the first row and the second row being formed on different finger belts and a conveying area being formed by sorting fingers of both finger belts.
- the first and second rows are preferably formed on the same finger belt, with a finger belt unit being able to have a further finger belt in addition to this finger belt formed with conveying areas, in particular with smaller spacing between the sorting fingers.
- a separating device for a root crop harvest flow which has at least two conveyor belts, in particular in the form of hedgehog or knobbed belts, as well as a finger belt unit according to the invention as described above or below, wherein the longitudinal direction of the finger belt runs at an angle to the longitudinal direction of the conveyor belts.
