Ordinary harvesting systems are based on pins or discs, which rotate in the same direction of the harvester, and; that get deep enough into the ground to reach the roots; extract, such as sugar beet wortis. 2 Vibrators can be added to increase yield. improve, loosen the roots from the soil and / or reduce the tare of the soil. | In addition to sugar beets, several root crops, | such as chicory or (chicory) or fodder beet, a long time in need of a better harvester, | A disadvantage of current harvesters is indeed that they leave some of the roots in the ground as a result of the tip of the root breaking.
    Also, especially in too dry or too wet conditions, the performance of the harvesting machine is reduced, for example due to a significant amount of soil that is
    ; 5 BE2019 / 5609 roots are removed or remain stuck to the harvesting installation. This means an extra weight to load and to; transport and later to scold. This also means that significant amounts of water and N energy are required to clean the roots and the harvesting device; to make. Current harvesting systems are complex and expensive to build. Consequently, any damage to a single element requires; time-consuming repairs, This is not convenient: fast: repairs are necessary, because the harvesting seasons often become; limited by weather conditions and a cell immobilized; rovier represents a significant amount of immobilized capital. ; Much effort has been made in downstream processing, for example to remove soil or to deliver the roots efficiently in a container; there are: however only a few improvements in the system to get the roots out of the soil.

    7 | BE2019 / 5609 DETAILED DESCRIPTION OF THE INVENTION; The inventor has developed a harvesting device 1 for; root crops "sugar beet an / GE chicory roots; (chicory) and / or fox beet), with a system operating in the opposite direction to the movement of the cogst machine; rotates.
    The harvesting device is made of a double | {concave} wheel 10. Each wheel 10 includes a number (flat); elements 6, which have an internal opening 7, This unique combination makes it unexpectedly possible to carefully remove the 19 roots from the ground (thus with:; less damage) and makes it possible to reduce the amount of soil | absorbed along with the roots. In addition, the total harvested yield is increased, 9 while energy consumption is reduced.
    The system 15 is also particularly robust; moreover, any damaged element can be easily replaced, usually on site without external hips. Therefore, a first feature of the present invention is: an apparatus for rooting a root crop; 20 comprising a dual wheel system 2 mounted on an ax 3, the axle 3 driving the dual wheel system to rotate in the opposite direction; 12 of the direction of movement 19 of the cogat machine, each part (wheel) of said dual wheel system 2; 25 comprises a number of elements 6 arranged such that to form a wheel 10, the elements 6 have an internal opening 7; A corresponding element is a half wheel 21 comprising at least one fastener 22 and two or three | Elements 6 comprising an opening 7, | Preferably, the fence 23 between the core 24 of the wheel or of the half-wheel 21 and the element 6 is smaller than 180 ° (i.e. between 100 ° and 160 °, preferably between 120 ° and 150 °) and / or the angle 25 between the core 24 of the wheel 10 or of the half wheel 21 and the element is less than 90 °, preferably between 30 ° and 60 °. 5 This half-wheel 21 is necessary for harvesting the root crops as described above, $ This half-wheel 21 is especially handio because this element | Can be easily replaced if damaged & this element can be stored in the seeder or near the harvester for quick replacement after; 19 damage {see below},: In this system, soil is loosened and taken up by the rotating wheel, part of which acts as a protective cushion between the root {sugar beet} and the elements 6, but almost all the extracted soil falls quickly on the soil, also through the holes 7. This system has been shown to be very efficient in dry soils, but also in wet soils.
    Stones have not damaged it. The elements 6 preferably comprise extra strong alloys or materials, such as iron and / or titanium and / or kevlar, A and it is preferred to rely on strong alloys, for example alloys containing iron, as well as a protective layer. , which may include tungsten-based alloys. Simple fastening means 22 are sufficient to carry out the present invention. The ax (shaft) 3 preferably has a polygonal cross-section; such as a square section (as shown in Figure 1b) or a hexagonal section; this polygonal section allows a better attachment of the wheel to the rotating ax {axis},
    9 | BE2019 / 5609 * As stated, even if the wheel 10 is very robust,; for example, compared to a pin system, the elements of the wheel 10 can be easily replaced if necessary. The wheel mounted on the ax (axle); is preferably formed, for example, by two parts 21.
    {the pair showing the division is represented by a double nearly vertical line, one above and one below the.
    axle 3 in figure 1b}, where each part has the same number of © elements 6 (usually 2 or 33. Even a whole wheel can be easily replaced, if necessary, so there is no absolute necessity for a wheel 10 consisting of two 21. The direction of rotation 18 opposite to the direction of the harvester 13 is essential in the present invention: the inventor has found that, under normal field conditions, where rows are not completely linear, or where some variation of the soil surface is, a; system that rotates in the same direction as the direction of; the harvesting machine results in many broken roots, which is: unacceptable, | Preferably, this root crop harvesting system is for harvesting | van Vechte roots ”, such as roots of Beta vulgaris, carrot, celeriac, chicory roots (chicory}, salsify, radish, turnip, but also tuber (potato,: manioc)} or rhizomes (turmeric, ginseng, ginger}. root crop system for harvesting "real roots", such as sugar beet roots: fodder beet roots or chicory roots (chicory. ; Advantageously, the elements become 5 of the double; wheel system 2 present on one wheel offset with between | 10 ° and 40 °, preferably between 15 ° and 35 °, more preferably between 20 ° and 30 °, even more preferably between 22 ° and 23 ° about 22.5 °) as compared to the corresponding
    10 | BE2019 / 5609; elements 6 present on the second wheel of the © system with double wheels 2. This corresponds to the angle: 14 varying from 15 ° and 35 °, more preferably from 20 ° and: 30 °, even more preferably from 22 ° and 23 ° (or approximately | 22.5 °}, | This makes it possible to apply local upward pressure on the root on one side and then on the other side (beet, chicory roots {chicoreijj; | usually each carrot (beet, chicory roots (chicory))} ° is pushed 4-5 times through the elements 6 of the rotating wheel 10: this reduces the risk of damage to the carrot {beet} and speeds up harvesting even without addition of vibrating parts, Preferably, the minimum distance 8 between the elements & of the first and second wheels 10 of the dual wheel system 2 is between 30 mm and 50 mm, in particular when the root crop is sugar beet or chicory.
    The maximum distance between the elements 6 of the first and second wheels of the dual wheel system 2 is | preferably between 170 mm and 210 mm, in particular | when the root crop is sugar beet (or chicory), the wheels of the dual wheel system 2 rotate at a speed between 40 rpm (revolutions per minute; rotational speed} and 170 rpm, preferably between 50 tonnes and 150 rpm, more preferably between 60 rpm and 120 rpm (eg,; about 77 rpm}. The speed can be adjusted, 9 for example to ensure that there are sufficient occurrences of (indirect, by means of a ground pad between the element 6 and the root) contact between the elements € and the roots 26, hence the number of (indirect) contacts | is a function of the speed of the cogst machine and of the number of elements 6. A correct speed also makes it
    11 {BE2019 / 5609 © possible to remove sufficient soil and even the; harvested roots 26 to the container end of the harvester and / or far from the cog step carat.
    On the other hand: too high a speed will lead to loss of energy and risk of damage to the roots 26.; Advantageously, the wheels of the dual system: wheels 2 each comprise 4 (or 5) or 6 elements 6; these elements 6 5 are preferably all identical, In view of the above, a too low number of elements 6 will require a too high speed of 8 the wheels, while those with too many elements 6: will no longer be able to get the roots 26 out of the ground 9 to push {extract}. : The elements 6 are evenly distributed around the wheel 10, | for example, if four elements 6 form the wheel 10, the four angles between two consecutive elements 6 of the same wheel are 90 °; if six elements 6 form the wheel 10, | are the six angles between two consecutive elements €; of the same wheel 60 °. | ; Preferably, the internal opening represents 7 of the | elements 6 of the wheels 10, or of the half wheels 21, / of the double wheel system 2 between 10% and 70% of the surface of this element 6, preferably between 20% and 60% of the surface, with more preferably between 30% and 50% of the surface.
    Preferably, the internal opening is the same in all elements 6 of the wheel 10 and / or of the dual-wheel system 2.: The size of the internal opening 7 is selected and / or; optimized to allow correct soil removal. ; Preferably, the elements 6 of the wheels 10, or of the half-wheels 21, of the dual-wheel system 2 have (substantially) a rectangular shape and / or are flat.
    12 | BE2019 / 5609 This allows part of the element to enter a few centimeters; get to the ground to push and extract the root,: Preferably, the elements 6 of the wheels of the | dual wheel system 2 {in addition to the main; rectangular shape} a trapezoidal shape, so that no right angle 5 serst enters the ground 3, This allows smoother access to the ground and hence lower energy consumption, as well as reduced damage to the ground 3 | harvest carrot. if Preferably, when observed, remains in a plane; view as in figure 3, no space left in the projected base of the elements 6 of the wheel 10 of the dual wheel system 2. This provides sen | continuous presence of elements 6 of the cogsrt device in the ground 2, Preferably the plane surfaces of two intersect: elements 6 of the two wheels 10 of the system with double | wheels when extended from the bottom 11 of the elements: 6 of the double wheel system 2 and / or the flat surfaces of two sections of the two wheels 10 of / the double wheel system when extended from the & base 12 of the elements 6 closest to the ax (axle) of the dual wheel system.
    In other words, the elements 6 of the two wheels of the wheel system 2 are oriented in two directions, forming an opening (in; two dimensions) at first carefully the root | to push (pry) and then to be more closed, in two dimensions, to cp the root in a gentle way; to lift from the ground; In other words, the angle 23 between the core 24 of the | wheel 10, or of the half wheel 21 and the element 6, is less than 180 ° (ie between 100 ° and 160 °, preferably between 120 ° and 150 ° and / or the angle between the core 74 of the wheel;

    Preferably the wheels are 10, the bisl (axle) 3 and the; elements 6 arranged in such a way that the elements & the ground | pierce at a depth of less than 10 cm, more preferably at a depth of less than 5 cm. !
    The maximum depth is not really limiting, but due to the | depth, energy costs and damage to the roots can be reduced, On the other hand, a depth of a few centimeters (for example at least 3 cm;, about 5 cm) is necessary to ensure the penetration of the elements 6 into the ground, in especially for uneven soils,
    The ax (axle) 3 can, if it has several harvesting devices 1 | drives {ie systems with double wheels 2), so in a multi-row machine, can be tilted along its length to give a constant force over a full rotation:
    40 only a fraction of the dual wheel system 2 mounted 7 on the axle 3 will attack the ground 3 first, then will; sen second [or the remaining) fraction of the dual wheel system 2 to attack the ground 9, when the force à / required to make the first fraction of the dual wheel system 2 is reduced, because it is no longer necessary to; to break the ground for this fraction.
    In other words, along the ax (axle) 3, the elements 6 have a wheel 10; of a first system with double wheels 2, preferably not the same height as the corresponding elements 6 of the corresponding wheel 10 of a second (or of a further) double wheel system 2 mounted on the same ax (axle) 3.
