    FLAX HARVESTING MACHINE WITH INTEGRATED VACUUM
    FIELD OF THE INVENTION
    The invention relates to a machine and a method for collecting Liberian plants cut and arranged on the ground of a field, but not only flax or hemp. In other words, the invention relates to a machine and a method for collecting Liberian plants in a field. Harvesting in a field is part of the harvest of Liberian plants and takes place after a period of retting in the field and a possible turning step.
    It is recalled that a Liberian plant is a plant containing Liberian fibers, that is to say spinnable plant fibers, the liber being a plant tissue contained in these fibers. Flax, hemp or jute are examples of a Liberian plant.
    STATE OF THE PRIOR ART
    During collection, Liberian plants are collected from the ground and are generally laden with dust. The presence of dust poses various problems: on the one hand it makes the stems heavier and on the other hand it complicates the treatment of the stems during the extraction of the fibers. There is therefore a need in this sense.
    PRESENTATION OF THE INVENTION
    BE2019 / 0067
    The present presentation concerns a machine for collecting Liberian plants.
    One embodiment relates to a machine for collecting stalks of Liberian plants in a field, comprising a system for collecting and conveying the stems, and a dedusting system configured to remove dust or the equivalent from the stems conveyed within the system of pickup and conveyance.
    Dust or equivalent means of course dust, but also any body less than 5mm (five millimeter). Subsequently, and unless otherwise indicated, by dust means dust or equivalent.
    The machine may be a self-supporting machine, that is to say that it has on-board locomotion means, in particular for moving in a field, or else towed. The machine has a front and a rear, a direction of advance extending between the front and the rear, and a direction of advance oriented according to the direction of advance from the rear to the front.
    It is understood that the pickup and conveyor system makes it possible to pick up the stems arranged on the ground and to convey them to between an inlet and an outlet of the pickup system. For example, may include a simple rowing wheel, which picks up the stems on one side and deposits the collected stems on the other side, for example to another device. In another example, the pickup and conveyor system has a wider conveyor path, for example from the front to the rear of the machine, but not necessarily. Furthermore, the machine may include another device for processing the rods downstream of the pickup and conveyor system, but not necessarily. For example, the machine may include only the pickup and conveyor system and the dust removal system.
    BE2019 / 0067
    For example, the dust removal system includes a dust extraction system, but not necessarily. It is understood that the dedusting system makes it possible to remove at least part of the dust or the equivalent when the rods are conveyed by the pickup and conveyor system. In other words, the machine is configured so that the rods loaded with dust upstream of the pickup and conveyor system (ie before entering the pickup and conveyor system) are at least partially cleaned of this dust downstream of the pickup and conveyor system (ie after passing through the pickup and conveyor system, at the outlet of the pickup and conveyor system).
    Such a system makes it possible to clean the stems of dust during collection, which lightens them for their transport and facilitates their subsequent treatment.
    In certain embodiments, the system for collecting and conveying the rods comprises a belt system for conveying the rods, and the dedusting system comprises a suction hood, the suction hood having an opening disposed opposite at least a portion of the belt system.
    It is understood that the belt system is a system which makes it possible, at the input, to pick up the rods from the ground and to convey them to the output of the belt system. By belt or equivalent means of course a belt but also any other member for conveying rods such as a chain, possibly equipped with paddles, blades, claws, etc.
    For example, the suction system includes a suction hood and a fan for suction, and possibly a cyclone to separate the air sucked from the dust with which it is charged.
    BE2019 / 0067
    It is understood that the opening of the extractor hood is arranged at a distance from the belt system making it possible to suck the dust from the rods conveyed into the belt system, without disturbing the conveyance of the rods. For example, the opening of the extractor hood is placed between 5 cm and 20 cm from the conveyed ply of rods. By rod ply is meant all of the rods conveyed in the belt system.
    Such a configuration allows dust to be easily removed from the rods when they are conveyed within the belt system.
    In certain embodiments, the belt system has a conveyor plane extending along a length and a width, the rods being conveyed within the pickup and conveyor system in the direction of the length of the belt system in s extending in the conveying plane, the opening of the suction hood extending substantially parallel to the conveying plane.
    It is understood that the conveying plane is defined by the direction of the length, that is to say the direction in which the belt (s) of the belt system extends, and the direction of width, defined by the width of the path for rods along the length direction within the belt system (ie direction perpendicular to the length direction). Thus, it is understood that the sheet of rods extends parallel to the conveying plane.
    For example, the opening of the hood is located above this plane (the top and the bottom being considered according to the direction of gravity), to vacuum the dust. The hood opening is arranged substantially parallel to the conveying plane. It is understood by substantially parallel that the angle between the plane defined by the opening of the hood and the conveying plane is less than or equal to 45 ° (forty-five degrees of angle).
    BE2019 / 0067
    Such a configuration makes it possible to improve the effect of the suction of the dust during its conveyance within the belt system.
    In certain embodiments, the opening has a length and a width, the width of the opening being greater than or equal to the width of the belt system while the length of the opening is less than or equal to the length of the system belts.
    In other words, the hood is configured to vacuum the dust over the entire width of the ply of rods which extends over the conveying plane, and over a portion of the length of the ply of rods.
    Such a configuration makes it possible to improve the effect of the suction of the dusts during their conveyance within the system of belts, by vacuuming over the entire width of the sheet, and therefore over the entire length of each rod.
    In certain embodiments, the hood is equipped with a confinement chamber, the belt system passing through the confinement chamber.
    It is understood that the confinement chamber isolates the part of the sheet which undergoes suction. This allows for uniform and more efficient suction. Such a configuration makes it possible to improve the effect of the dust suction during their conveying within the belt system, by making sure to only suck the dust from the rods present in the confinement chamber and to improve suction depression.
    In certain embodiments, the pick-up and conveyor device comprises an inlet arranged on a front side of the machine, and an outlet arranged on a rear side of the machine, a cyclone of the dedusting system having an outlet
    BE2019 / 0067 arranged on the rear side of the machine relative to the outlet of the pickup and conveyor system.
    We understand that a cyclone is a device for separating the air and dust sucked by the hood. By arranging the outlet of the cyclone, ie the outlet in the open air to reject the dust outside, behind the outlet of the pickup and conveyor system, it is ensured that the release of the dust does not pollute the cleaned stems. Such a configuration improves the cleaning of the rods.
    The present presentation also relates to a method of collecting stems of Liberian plants in a field.
    One embodiment relates to a method of picking stems of Liberian plants in a field, in which stems are collected from the ground and then conveyed, and dust or equivalent is sucked from the stems during their conveyance.
    In some embodiments, the collected and sucked stems are then treated, the treatment being carried out after aspiration.
    By treating is meant any operation that can be carried out on a rod that has just been picked up, such as turning it over, spraying it with a product or water, conditioning it, etc.
    In some embodiments, the Liberian plant is flax or hemp.
    Such a process is particularly well suited for collecting flax or hemp, after a period of retting in the open field.
    BRIEF DESCRIPTION OF THE DRAWINGS
    BE2019 / 0067
    The invention and its advantages will be better understood on reading the detailed description given below of different embodiments of the invention given by way of nonlimiting examples. This description refers to the pages of attached figures, on which:
    - Figure 1 shows a side view of a machine for collecting stems of Liberian plants, free-standing,
    FIG. 2 represents a top view of the machine for collecting stems of Liberian plants of FIG. 1,
    FIG. 3 represents a side view of a machine for collecting stems of towed Liberian plants, and
    FIG. 4 represents a top view of the machine for collecting stems of Liberian plants of FIG. 3.
    DETAILED DESCRIPTION OF EMBODIMENTS
    Figures 1 to 4 show a machine 10 for picking stems of Liberian plants in a field. For the sake of clarity, the figures are schematic. Figures 1 and 2 show a self-supporting machine 10 while Figures 3 and 4 show a towed machine 10 ’. Unless otherwise indicated, the operation of the two machines 10 and 10 is identical.
    The machine 10 is a self-supporting machine comprising means of locomotion, in this example wheels 11, a motor (not shown) for driving the wheels 11, and a cockpit 12. The machine 10 has a front side CAV, a side rear CAR, a direction of advance X extending between the front side CAV and the rear side CAR, the arrow I representing the direction of advance of the machine 10 in normal operation, this direction of advance being
    BE2019 / 0067 oriented from the rear side CAR to the front side CAV in the direction of travel X.
    The machine 10 comprises a pick-up and conveyor system 20 comprising a belt system 200. In this example, the belt system comprises a single belt 203 equipped with pick-up claws (or spike belt), driven by a drive wheel 201b, and a pick-up wheel 201a, driven in rotation by the drive wheel 201b, via the belt 203.
    The pick-up and conveyor system 20, and more particularly the belt system 200 has an inlet 202a and an outlet 202b, the outlet 202b being arranged behind the inlet 202a with respect to the direction of advance X machine 10.
    The direction of length 1 is defined as the direction connecting the inlet and outlet of the pickup and conveyor system 20. Note that this direction merges with the conveyor direction. The direction of the width L is the direction which is perpendicular to the direction of the length 1 and parallel to the horizontal when the machine 10 is resting on its means of locomotion.
    A conveying plane PI is defined according to the length 1 and width L directions previously defined, at the level of the belt system 200, and more particularly of the upper part of the belt 203.
    The pickup and conveyor system 20, and more particularly the belt system 200, is configured to pick up stems of Liberian plants in a field in this example via the pickup wheel 201a, the stems then being arranged in swath according to the advancement direction X on belt 203 ..
    BE2019 / 0067
    The pickup operation makes it possible to form a ply of rods on the pickup and conveyor system 20. The ply of rods is then conveyed to the rear side CAR of the machine. In other words, the ply of rods is conveyed from the inlet 202a to the outlet 202b by the belt 203.
    The collection and conveying system 20 can be raised by rotation about an axis (A), which makes it possible to raise the front part of the device (ie the inlet 202a) by at least 20 cm from the ground, by means also known to those skilled in the art, for example a jack not shown. In other words, the pickup and conveyor system 20 is movable between a low position (ie working, the wheel 205 being in contact with the ground) and a high position (ie transporting, for example for moving the machine on a road, the wheel 205 being raised and not touching the ground). For example, the height of the inlet 202a of the pickup and conveyor system 20, and more precisely of the belt system 200, in the lower position is adjustable via the connection to the wheel 205, and this in a manner known elsewhere by the invention. skilled in the art.
    The machine 10 comprises a conditioning device 300 disposed behind the outlet 202b of the belt system 200. It extends from the rear side CAR of the machine 10. This conditioning device 300 is configured to condition the stems of the Liberian plant. In this example, the packaging device 300 comprises a winder, the rods being rolled up and then deposited in the field, at outlet 301 of the packaging device 300. According to a variant, the packaging device is replaced by a turning device, which makes it possible to turn the stems over and then put them back in the field. Such an operation is in particular part in the retting of the stems in the field, known moreover by a person skilled in the art.
    As shown in FIGS. 1 and 2, the machine 10 comprises a dedusting system comprising a hood 101, a flexible pipe 105, a fan 106, a pipe 107 and a cyclone 108.
    BE2019 / 0067
    The hood 101 is arranged so as to present an opening 101a with respect to the belt system 200. In this example, the opening is located above the conveying plane PI and therefore above the ply of rods, in this example at 8 cm. In addition, the plane P2 of the opening is parallel to the conveying plane PI. In operation, the hood 101 aspires at a flow rate greater than 1300 m 3 / h (cubic meter per hour).
    The hood 101 comprises a confinement chamber 103. This confinement chamber 103 comprises a plate 101b which is arranged to frame the opening 101a. This plate 101b is coplanar with the opening 101a, extends over a shorter length and a greater width than that of the belt system 200 (these lengths and widths are compared on the basis defined by the length directions (1 ) and width (L)). In other words, the length 11 of the plate 101b is less than the length 12 of the belt system 200 and the width L1 of the plate 101b is greater than the width L2 of the belt system 200.
    The containment chamber 103 also includes containment curtains 104 are fixed on the periphery of the plate 101a and extend vertically (according to the direction of gravity), towards the ground. The confinement chamber 103 delimits an internal volume which includes at least part of the pick-up and conveyor system 20. Thus, the suction of the ply of rods is applied within this confinement chamber 103. In this example the curtains containment 104 include flexible PVC straps.
    The flexible pipe 105 connects the outlet of the hood 101 to the inlet of the fan 106. The fan 106 is fixed to the chassis of the machine 10 and disposed above the plate 101b and behind the opening 101a. Fan 106 is used to generate vacuum for suction.
    BE2019 / 0067
    The flexibility of the flexible pipe 105 allows a certain mobility of the hood 101 in order to guarantee the mobility of the pick-up and conveying system 20, without the hood 101 interfering with this movement. In other words, thanks to the flexible pipe 105, it is easy to adjust the height of the inlet 202a, the hood 101 following the movement, without impacting the rest of the dust removal system.
    When the dust removal system is in operation, the air speed in the pipe is greater than 19 m / s
    A pipe 107 connects the outlet of the fan 106 to the inlet of the cyclone 108. The cyclone 108 is arranged on the rear side CAR of the machine 10. Also, the cyclone 108 is arranged next to the conditioning system 300 so that it does not hinder the expulsion of the wound rods by the packaging system 300.
    Cyclone 108 separates the dust from the air which has been sucked from the rod ply, then rejects it from the rear side CAR of the machine 10, towards the ground. Air is expelled into the atmosphere. In this example, the cyclone 108 is arranged vertically (considered in the direction of gravity), its outlet is therefore also on the rear side of the machine 10, directly above the cyclone 108.
    Figures 3 and 4 show a machine 10 'similar in all respects to the machine 10 of Figures let 2, except that it is towed instead of being self-supporting. Thus, the machine 10 'has no integrated means of locomotion, and is coupled to a tractor 50. The rest of the machine 10' being identical to the machine 10, it is not described in detail, the common elements having the same reference sign.
    In operation, the machine 10 collects the stems of Liberian plant arranged in a field and on the ground using the pickup and conveying system 20. The stems are then conveyed in a sheet from the inlet 202a to the outlet 202b of
    BE2019 / 0067 belt system 200. During this path, the sheet passes through the confinement chamber 103 which sucks the dust present on the rods.
    The ply of rods is then deposited in the packaging system 300, behind the outlet 202b of the belt system 200. In the example illustrated by the figures, the rods are wound in bales in the packaging system 300. The bales leave the conditioning system 300 through its outlet 301 and are arranged in the field.
    This machine is operational for collecting flax or hemp.
    Although the present invention has been described with reference to specific exemplary embodiments, it is obvious that modifications and changes can be made to these examples without departing from the general scope of the invention as defined by the claims. In particular, individual features of the different illustrated / mentioned embodiments can be combined in additional embodiments. Therefore, the description and the drawings should be considered in an illustrative rather than restrictive sense.
    It is also obvious that all the characteristics described with reference to a process can be transposed, alone or in combination, to a device, and conversely, all the characteristics described with reference to a device can be transposed, alone or in combination, to a process.
