    Breaker for stones
    The present invention relates to a crusher for stones of a scum line, in particular of flax or another plant that can undergo such a refraction of the stones present in the layer of plants, followed by scum. Such a scoring line consists of a plurality of machines which are arranged one behind the other on one line, wherein the flax layers enter the said scrub line in the form of spheres being shredded, and wherein the shredded layer of flax undergoes a number of steps which ensure obtaining the end product according to which the flax fibers are removed from the stems and where the flax shives are removed.
    Several operations precede the scoring, which is specifically intended to remove the fibers from the stems. These upstream operations consist of arranging the flax stalks, aligning them, removing the seeds, removing the waste, etc. A repel process as described in the French is carried out when performing the operations patent application registered under the number FR 0 605 893, the intention of which is to remove the capsules and seed beets contained in the flax stalks and, moreover, to remove the stones and other waste contained in the flax layer before to go scampering. During these pre-swinging operations, the flax stems are retained in the central portion by means of a link chain held together by a T-shaped belt, even by means of two flat or toothed belts that pinch said stems in the middle.
    The flax layers that enter the scum line are sometimes loaded with stones that could block the link chains during these preceding operations, or during the scum itself. To remedy this inconvenience, the scrub line is provided with a brick breaker upstream. This brick breaker has, as the name implies, the aim of breaking the bricks in order to minimize the risks of blocking the link chain as well as causing malfunctions further down the scam line. Such a crusher is placed on the scrub lines between the repelling machine which ensures the repelling of the flax balls and the distributor which reduces the thickness of the layer.
    The crusher consists of a conveyor belt arranged upstream, which ensures the loading of the layer of flax that is pre-peeled by means of the repelling machine. The crusher also comprises a conveyor belt arranged downstream, which, when leaving the layer of flax from the crusher, ensures direct transfer to the distributor. This conveyor belt may consist of stars, a carpet, a smooth or nailed belt, etc. The conveyor belt also has two rock crushing rollers arranged between the upstream conveyor belt and the downstream conveyor belt. In this way the layer of flax, in which stones are located, is transported by means of the upstream conveyor belt to the two breaking rollers, said layer passing through said rollers, which causes the stones to break, the layer after breaking of the stones is transported on the downstream conveyor belt, which takes the layer of flax to the next step. These upstream and downstream conveyor belts can in any case consist respectively of a conveyor belt arranged at the exit of an upstream machine of the breaking rollers, and of a conveyor belt arranged at the exit of a downstream machine of said breaking rollers.
    The bricks currently known for bricks ensure the destruction of the bricks present in the layer of flax in the central part, namely the central zone used for retaining the flax between the link chain and the T-shaped belt or between two flat or toothed belts, which ensure that the flax stems are pierced. One of the problems comes from the difficulty in controlling the passage of the layer of flax through the upstream conveyor belt to the downstream conveyor belt. This difficulty is particularly emphasized when the flax stems are not rough enough or when these flax stems are slightly damp, stiff or poorly aligned, even misplaced with respect to the progress trajeet.
    In order to properly transport the flax to the crushing rollers, said crusher is equipped with guide rods which are continuously arranged on either side of the crushing rollers with the upstream conveyor belt and the downstream conveyor belt, which are responsible for transporting the flax and guiding for and after the passage through the two rollers. These guide rods can in any case be arranged on the conveyor belt at the exit of the upstream machine and arranged on the conveyor belt at the entrance of the downstream machine, on either side of the breaking rollers. In the known crushers, the upstream and downstream conveyor belts are arranged linearly, the two rollers being arranged vertically, one above the other, and the guide rods also being linearly in the same plane as the two upstream and downstream conveyor belts. Moreover, this plane, which defines the linear trajectory of the layer of flax on the upstream and downstream conveyor belts and on the guide rods, is arranged above a horizontal plane which runs along the axis of rotation of the lower crushing roller. The lack of rigidity or stiffness of the flax stems, even their poor organization, tends to weaken it between the guide bars, which causes inconvenience to cause accumulations at the exit of the crushing rollers. In addition, the downstream guide rods are arranged with a deviation relative to the said rollers, this deviation being necessary because of safety regulations, namely to prevent that a possible accumulation can occur due to the remains of broken stones, even from stones remained intact, left in the layer after the passage through the crushers. Such inconvenience of stone residues is quite common in current crushers, since they are provided with rollers extending only over the central portion for the purpose of crushing stones in the zone corresponding to the link chain.
    In addition, if the flax stems are of a considerable size, they tend to bend at the sides, i.e. at the ends of the stems, which is also inconvenient in the area of their placement on the guide rods to prevent proper transmission to the downstream conveyor belt. entails, thus causing a possible accumulation of the downstream conveyor belt.
    The invention helps to remedy the inconveniences cited here, and in particular ensures a proper transfer of the flax stalks, after their passage between the crushing rollers, to the downstream conveyor belt. This transfer is also ensured at the level of the upstream conveyor belt during the insertion of the flax between the two breaking rollers. In addition, the invention provides the advantage of ensuring the breaking of the bricks that are in the flax stems along its entire length, which prevents bricks from being located in other downstream circuits in the scams line, with the risk of serious breakdowns and cause wear, in particular at the level of the air circuits, the seed department or in the flax shives or flax locks.
    For this reason, the invention relates to a crusher for stones from a flax line or from any other plant that has the same properties. The brick breaker has a linear conveyor belt mounted upstream, and a linear conveyor belt mounted downstream, said downstream conveyor belt also being the upstream portion of a distributor, of a turbine or other machine. These two conveyor belts are responsible for transporting the layer of flax on the scams line. The crushing rollers are arranged between the upstream and downstream conveyor belts, which cause the crushing or crushing of the bricks present in the flax layer. Thus, the layer of flax comprising bricks is transported from the upstream conveyor belt through the two rollers, to arrive at the downstream conveyor belt, wherein the bricks present in the flax layer are mown during their passage between said rollers. These two rollers have an axis of rotation which is arranged substantially longitudinally with respect to the progression path of the layer of flax on the crusher and the scoring line. These rotational axes are arranged substantially parallel to each other. Moreover, the first roll rotates clockwise, in accordance with the direction of progress of the layer of flax, and the second roll rotates in the trigonometric sense.
    According to the invention, the front end of the upstream conveyor belt is located near the first roller. Moreover, this front end is arranged above a horizontal plane Pi, passing through the axis of rotation of the first roller. In the most extreme case it can be arranged at the level of the horizontal plane Pi. This front end is also arranged between two vertical surfaces P2 and P3 which respectively run along the rear end of the first roll and the point of contact between said first roll and the second roll. It can be applied in the extreme case in the vertical plane P2.
    Moreover, the rear end of the downstream conveyor belt is located near the first roller and it is arranged below the horizontal plane Pi along the axis of rotation of the first roller. In the same way, this rear end of the downstream conveyor belt is arranged upstream with respect to a vertical plane P4, passing along the front end of the first roller.
    These features ensure on the one hand a reliable transfer of the flax stalks from the upstream conveyor belt to the first break roll, which rotates in the direction of progression of the layer of flax, which ensures its transport for the passage between the two break rollers. On the other hand, the position of the downstream conveyor belt ensures the transport of the said broken layer of flax by gravity, while ensuring that any risk of accumulation at the exit of the rollers is avoided. In addition, this makes it possible to omit the additional guide rods at the level of the downstream conveyor belt at the output of the said rollers.
    In addition, the position of the two rollers determines a plane P5 passing through the axes of rotation of said rollers by forming an angle with a certain plane P6 through the linear trajectory of the layer on the second conveyor belt, this angle preferably being included between 0 and 90 °. We can view an angle of more than 90 ° between these two planes P5 and P6, in particular by inclining the linear trajectory of the layer on the second conveyor belt to the second conveyor belt of the crushing rollers arranged downstream.
    According to another aspect of the invention, the length of the crushing rollers is plotted to that extent to ensure integral refraction of the flax layer over the full length of the stems. This is intended to ensure the refraction of all stones present in the layer of flax and thus to eliminate any risk of malfunctioning on the scum line.
    The present invention will be better understood after reading the description that will follow, a description that applies to the figures, including: 1 which schematically represents a crusher according to the ancient art; FIG. 2 which according to the invention schematically represents a first embodiment of the breaker; FIG. 3 which according to the invention schematically represents a second method of realization of the breaker; FIG. 4 which according to the invention schematically represents a third method of realization of the breaker; FIG. 5 which according to the invention schematically shows the preferred method of realization of the concept of the crusher and its constituent elements.
    The breaker which is the subject of the present invention consists of an upstream conveyor belt and a downstream conveyor belt between which two rollers are arranged arranged in such a way that they break the bricks present in the layer of flax.
    According to the breakers of the ancient art, as illustrated in FIG. 1, the whole of the loading line of the crusher 1, namely the upstream conveyor belt 2 and the downstream conveyor belt 3, as well as the position of the two rollers 4, 5 is arranged in a linear manner, viz. That it is responsible for the transfer of the upstream to the downstream whereby the two rollers 4, 5 pass through the crushers and a straight line path of the layer of flax 6 is maintained. This view requires the use of guide rods, both in the upstream and in the downstream portion, to allow transfer between the upstream conveyor belt and the rollers and between the rollers and the downstream conveyor belt, which entails the aforementioned inconveniences.
    In contrast to the ancient art, the crusher 10, 11, 12 of the invention illustrated in Figs. 2 and 5, advantageously another flow of the flax layer 13 from the upstream to the downstream, thereby helping to resolve the inconveniences of the old art. For this purpose, the upstream conveyor belt C 1, C 2, C 3 is linear, being arranged in such a way that its front end 14, 15, 16 is arranged in a similar manner to the first roller 17, 18, 19, which rotates clockwise, said end 14, 15, 16 being arranged between a vertical plane P2 along the rear end 20, 21, 22 of said first roller, and a vertical plane P3 along the tangent point 23, 24, 25 between the first roller 17, 18, 19 and the second roll 26, 27, 28, at the height of which the breaking of the stones is carried out. Thus the layer of flax 13 goes from the front end 14, 15, 16 of the upstream conveyor belt onto the first roll, tending to carry the layer of flax 13 through the two rollers, in view of the direction of the hour rotation of the first roll and the arrangement of the front end 14, 15, 16 of the upstream conveyor belt. In addition, the second roller 26, 27, 28 rotates in the reverse direction of the first roller, which, once the layer of flax 13 has penetrated between said rollers, also tends to promote its entrainment to the downstream portion. Moreover, the point of the end 14, 15, 16 of the upstream conveyor belt is arranged below the horizontal plane Pi, passing through the axis of rotation 29, 30, 31 of the first roller.
    In addition, the rear end 32, 33, 34 of the linear conveyor belt C4, C5, C6 is arranged below said horizontal plane P1, the rear end 32, 33, 34 moreover being located in the rear portion relative to the vertical plane P4. passing along the front end 35, 36, 37 of the first roll. In this way, when the layer of flax has passed through the two break rollers, the first roller 17, 18, 19 continues to carry said layer, the position of the rear end 32, 33, 34 of the downstream conveyor belt arranging said layer on top. In addition, this position solves any accumulation problem that might occur due to the remains of the broken or crushed stones that are also on the carpet of the downstream conveyor belt, which will eventually be removed during the passage through the repel machine. According to this view, it is not necessary to use guide rods in the downstream portion, since the arrangement is done directly on the carpet of the downstream conveyor belt C4, C5, C6 at the exit of the rollers. Moreover, this also avoids any risk of accumulation that could occur due to the bending of the stems when they are neither rigid nor rigid.
    According to another aspect of the invention, the length of the rollers is plotted to that extent to ensure the passage of the entire flax stems through said rollers to insure the breaking of all bricks that are inside the flax layer. The length of these rollers will therefore be remarkably identical to the width of the upstream and downstream conveyor belts. In addition, the two rollers are arranged in such a way that the plane P5 passing through the rotation axes 29, 30, 31 and 38, 39, 40 of said rollers with the linear downstream conveyor belt, on which a plane P6 corresponding to the linear displacement trajectory of the layer of flax, forming an angle Φ which preferably comprises between 0 and 90 °.
    Multiple arrangements of the two rollers 17, 18, 19 and 26, 27, 28 are possible according to the preferred embodiment of the invention, and as illustrated in FIGS. 2 to 4.
    According to a first realization illustrated in FIG. 2, the two rollers 17 and 26 are arranged one above the other, the second roll 26 being arranged on the first roll 17, the angle Φ formed between the horizontal plane P6 defining the horizontal path on the second conveyor belt and the vertical plane P5 passing through the two axes of rotation 29, 38 of the rollers, forming a right angle (angle Φ = 90 °).
    According to the variant illustrated in FIG. 3, the two rollers 18, 27 are arranged in an inclined manner, so that the plane P5 passing through the two rotation axes 30, 39 defines an angle Φ between 0 and 90 °, for example 60 °, with the horizontal plane P6.
    According to a third variant illustrated in FIG. 4, the two rollers 19, 28 are arranged horizontally, the second roller 28 being arranged downstream with respect to the first roller 19, the horizontal plane P5 passing through the two rotation axes 31, 40 being angled Φ with the horizontal plane P6 forms zero, namely that the two planes P5, P6 are parallel (Φ = 0). According to this view, the second roller 28 has the advantage of promoting the entrainment of the layer of flax 13 once the passage and the breaking of the bricks has been realized.
    Other methods of implementation are possible. We can indeed provide an angle Φ between planes P5 and P6 that is greater than 90 ° and that can come close to 180, in particular by placing the two rollers next to each other, as illustrated in FIG. 2, which corresponds to a vertical plane P5 and the downward slanting of the linear displacement trace of the layer of flax of the downstream conveyor belt on which the plane P6 is determined. For example, by inclining the downstream conveyor belt with an angle of 45 ° downwards, an angle Φ is obtained between P5 and P6, which is equal to 135 °.
    FIG. 5 sets a conception as schematized in FIG. 4 for. According to this view, the upstream conveyor belt C3 extends linearly and preferably comprises guide means 41 which form the front end 16 of the upstream conveyor belt. These guide means 41 are in particular formed by the guide rods which are longitudinally distributed over the full width of the upstream conveyor belt C3 in such a way that the holding in position of the flax stems is guaranteed, in particular when they are neither rigid nor rigid. We can also provide such guide elements on the schematic breakers in FIG. 2 and 3. Regarding the schematic breaker in FIG. 4 and 5, the end 16 of the guide rods is arranged in a similar manner on the first roll 19 and just above its upper end 42, which promotes entrainment through the two rollers 19, 28, for breaking the stones. In addition, the horizontal position of the two rollers 19, 28 promotes entrainment of the layer by the second roller 28, arranged in front and rotating in the trigonometric direction and in the progression direction of the downstream conveyor belt C6. The two rollers include teeth 43, 44 arranged for proper repelling from one to the other, as illustrated in FIG. 5 and for ensuring the breaking of the stones in this way.
    Preferably, as illustrated in FIG. 5, the downstream conveyor belt formed by a linear carpet comprising at least one belt 45 with nails 46, which promote entrainment of the layer of flax. Such a conveyor belt is also possible on the upstream conveyor belt. The progress speed on the upstream conveyor belt C3 and on the downstream conveyor belt C6 and the rotation speed of the rollers 19, 28 are preferably synchronous, to the extent that breaking of the bricks is ensured, without, however, a continuity of the layer of flax on the scrub line out of sight.
    The view of the breaker 12 as illustrated in FIG. 5 has the advantage of limiting the obstruction of the installation, since it allows the superposition of the rollers 19, 28 of the crushers relative to the downstream conveyor belt C6.
    Such a linear downstream conveyor belt, provided with nailed belts, as illustrated in FIG. 5, it will be preferable if said downstream conveyor belt is inclined downwards, the angle Φ between P5 and P6 being consequently greater than 90 ° (90 ° <Φ <180 °), said nails of the belts having a retaining play a role with regard to the flax stems on the linear carpet that is inclined downwards.
    Other achievements are possible without prejudice to the scope of the present invention. The characteristics described above for the functions shown in FIG. The breaker illustrated in Fig. 5 is particularly possible for the breakers as schematically illustrated in Figs. 2 and 3.
