    [0001] [0001] The present invention relates to a sugarcane harvesting machine. More particularly, the invention relates to a sugarcane harvesting machine having an inclined conveyor that transports sections of sugar cane from the harvesting machine in a collection cart. Background of the invention
    [0002] [0002] A sugarcane harvesting machine of this type is known from US 3,830,046. An inclined conveyor is positioned at the end of the product flow through this machine, and transports sections of sugar cane, formed by grinding the sugarcane stalks cut in the machine, in a collection cart. The inclined conveyor has two continuous traction mechanisms, designed as chains, which extend parallel to each other and are connected by steel carriers.
    [0003] [0003] The chains pass over upper driving wheels and lower deflection wheels which are together driven and positioned in the feeding area of the sugarcane sections. The inclined conveyor is designed as a scraper conveyor; that is, having a sturdy steel plate base that forms a passage surface along the entire length of the inclined conveyor and scrapes the loaders, thus transferring the sugar cane sections upwards on the base of the steel sheet.
    [0004] [0004] A first and a second extractors, which are used to remove residues and the like from the sugarcane sections, are positioned in the sugarcane harvesting machine. The extractors operate through a rotor that generates an air flow that carries waste along and transports it outside. A first extractor is located in a transition zone of the sugar cane sections on the inclined conveyor, while the second extractor is positioned on the tip of the inclined conveyor and removes the residues from the sugar cane sections when they fall. from the upper end of the tilted conveyor and fall into the collection car.
    [0005] [0005] Such angled conveyors described above with reference to the prior art have many disadvantages. Steel chains wear out very quickly due to the adhesion of sand and dust. Additionally, they disengage even after a few hours of operation due to the actuation tension, causing the teeth to come out of the drive wheels. For this reason, the conveyor requires continuous monitoring and maintenance, yet it has a short service life. A high level of wear and high energy consumption occurs during the operation of the tilted conveyor, since the sugar cane sections are scraped during transport on the steel base of the loader. This is also associated with a high level of noise due to metal to metal contact. Additionally, the conveyor's scraper base, which is made of solid steel sheet, is very heavy. An additional drawback is that, due to the scraper base that acts as a barrier, the inclined conveyor, although perforated, carries almost all impurities with it, resulting only in a very low sieving and cleaning effect, and thus subjecting the second heavy load extractor. Objectives and summary of the invention
    [0006] [0006] An objective of the invention is to overcome the drawbacks of the prior art.
    [0007] [0007] Another objective of the invention is to provide a sugarcane harvesting machine of the type having an inclined conveyor, the inclined conveyor of which has a long useful life with low maintenance, and which at the same time works quietly and energy efficient way with a high cleaning effect.

A máquina de colheita de cana-de-açúcar, de acordo com a invenção, inclui um transportador inclinado que transporta seções de cana-de-açúcar a partir da máquina de colheita para um carro de coleta, e tem pelo menos dois mecanismos de tração, que se estendem um paralelo ao outro e tendo carregadores contínuos, e que circulam sobre rodas motrizes superiores, e rodas de deflexão inferiores as quais são juntamente conduzidas e posicionadas na área de alimentação das seções de cana-de-açúcar. Os mecanismos de tração contínuos são configurados como correias feitas de tecido de polímero reticulado de camada reforçada; e ressaltos posicionados a uma distância um do outro e estando posicionados sobre um lado inferior das correias para o acionamento pelas rodas motrizes, de forma forçada, as correias estando uma conectada a outra por uma pluralidade de hastes transversais, as quais como um todo, forma uma base de peneiramento e base de apoio, e as rodas de deflexão as quais são juntamente conduzidas sendo configuradas como rodas individuais.[0008] This objective is achieved according to the invention through a sugarcane harvesting machine including: a) an inclined conveyor; b) the inclined conveyor carrying sections of sugar cane from the harvesting machine to a collection car and the inclined conveyor having at least two traction mechanisms that extend parallel to each other and having continuous loaders, the which circulate on upper driving wheels and lower deflection wheels which are driven together and positioned in the feeding area of the sugarcane sections; c) at least two traction mechanisms are continuous traction mechanisms configured as belts made of cross-linked reinforced polymer fabric; and d) projections are positioned at a distance from each other and are positioned on a lower side of the belts to be driven by the driving wheels, the belts being forcedly connected to each other by a plurality of transverse rods, which as a whole, they form a sieving base and support base, and the lower deflection wheels which are driven together and configured as individual wheels.The sugar cane harvesting machine according to the invention includes an inclined conveyor that transports sections of sugar cane from the harvesting machine to a collection car, and has at least two traction mechanisms , which extend parallel to each other and have continuous loaders, and which circulate on upper driving wheels, and lower deflection wheels which are together driven and positioned in the feeding area of the sugarcane sections. The continuous traction mechanisms are configured as belts made of cross-linked reinforced polymer fabric; and projections positioned at a distance from each other and being positioned on a lower side of the belts for driving by the driving wheels, forcibly, the belts being connected to each other by a plurality of transverse rods, which as a whole, form a screening base and support base, and the deflection wheels which are driven together and configured as individual wheels.
    [0009] [0009] According to the invention, the traction mechanisms of the inclined conveyor are straps made of polymer fabric that are forced into force through the shoulders. As a result, the polymer material moves over the metal when the tilted conveyor is activated, so that on the one hand the conveyor runs in silence, and on the other hand minimal wear occurs, resulting in a long service life. Retightening the fabric polymer belts is not necessary. In addition, energy is conserved, since the sugarcane sections are loaded onto the cross rods that connect the belts, and are no longer scraped. At the same time, this results in increased transport capacity.
    [0010] [0010] In general, the inclined conveyor can have a configuration that is much more open at the sides and at the bottom, resulting in a high cleaning and sieving effect. The scraper base is dispensed with, so that the inclined conveyor together with the transverse rods connecting the drive belts is opened at the bottom, which is only possible by the design of the belt deflection wheels as individual wheels, that is, not connected to each other by an axis, thus avoiding the wrapping of plant material around that axis. Opening on the sides of the inclined conveyor is possible due to the fact that the belts, unlike the roller chains known in the prior art, do not require lateral guide rails, and on the contrary, can be guided on the support rollers. Due to the high cleaning and sieving effect of the inclined conveyor, the second extractor at the upper end of the inclined conveyor can be dispensed with.

    [0013] [0013] The invention is explained in greater detail below with reference to an example of embodiment. The associated figures show the following: Brief description of the drawings

    [0015] [0015] Figure 2 shows an enlarged detail A according to Figure 1;
    [0016] [0016] Figure 3 shows an angled view in perspective, from the top right, of the illustration according to Figure 2; and
    [0017] [0017] Figure 4 shows a perspective view of the inside of an inclined conveyor deflection wheel with circulating belts and partially cut cross rods. Detailed description of the invention
    [0018] [0018] Figure 1 shows a self-propelled sugarcane harvesting machine 1. Track caterpillars 2 are provided with the chassis, although rubber tires can also be used.
    [0019] [0019] The sugarcane harvesting machine 1 has a driver's cab 3 from which an operator can observe and control the harvesting operation. The harvesting operation starts with cutting the top of the sugar cane plants before the stems pass through the harvesting machine. The top cut is performed by means of an extreme cutter 4 which is mounted on the sugar cane harvesting machine 1 through a structure 5. The cut stalks are then grasped by two rotating line dividers 6 arranged in parallel one to the other, and driven into the machine. In the machine, the stalks are separated from the underground roots by two basic cutting discs against rotary not shown. The sugarcane stalks are then fed through transport devices, not shown, and cutting rolls, also not shown. The base cutting discs cut the sugarcane stalks into sections of sugar cane, also known as blanks, which subsequently enter a rotating conveyor that is equipped with deflector rolls 7. These rolls 7 throw the sugar cane sections on a curved path within a collection funnel 8. A first extractor 9 having a suction fan is positioned above the path of the sugar cane sections. This fan pulls impurities, for example, leaves from the free fall of the flow of the sugarcane sections, and discharging them outside. The collection hopper 8 is positioned at a feed end 18 of an inclined conveyor 10.
    [0020] [0020] The sugarcane sections pass from the collection funnel 8 to the inclined conveyor 10, which carries them upwards to a discharge end 11. At this discharge end 11 the sugarcane sections sugar leaves the inclined conveyor 10 and falls in free fall in a co-path collection car. A second extractor 12, which extracts any impurities from the flow of the sugar cane sections that were transported through the inclined conveyor 10 and discharges them outside, is positioned above the discharge end 11.
    [0021] [0021] The inclined conveyor 10 has two continuous traction mechanisms, extending parallel to each other, which are configured as belts 13 made of cross-linked reinforced polymer fabric. The traction mechanisms circulate on drive wheels 14 located at the discharge end 11 and deflection wheels 15 which are positioned at the feed end 18 and driven together. The upper driver 33 and the lower driver 24, of the inclined conveyor 10, are supported by support rollers 16, and their angle of inclination is changed by means of deflection rollers 17.
    [0022] [0022] Figure 4 illustrates only one side of the inclined conveyor 10 in partial detail. The other side has a mirror image, so the following statements apply to that side as well.
    [0023] [0023] The shoulders 19, which are separated in a division x from each other, are provided on the lower side of the belts 13. These shoulders 19 are used for the forced driving of the inclined conveyor 10. For this purpose, a drive device ( (not shown) of the driving wheels 14 engages with the openings 20 formed between the shoulders 19. Conceptions of this type are known from the prior art, and consequently, are not explained in more detail here.
    [0024] [0024] The distance between the belts 13 is established by the rods 21 that are transversely positioned in relation to the transport direction of the inclined conveyor 10 and one parallel to the other, and that at their ends are connected to the belts 13. For this purpose, the rods 21 are provided with flat end regions 21.1 which are produced by forging from round rods and which rest on the straps 13. The extreme regions 21.1 have two holes, separated from each other at a certain distance, for fixing elements, for example rivets 22, which traverse the flat end regions 21.1, as well as the straps 13. The rods 21 rest on the straps 13 in the area above the openings 20; that is, the nails have the same division x as the shoulders 19.
    [0025] [0025] Crossbars 23 are welded on the lower side of the rods 21, in the form of strips of sheet steel, next to the top of which in each case two additional rods 21.2 are welded positioned parallel to the rods 21 and at a distance from them. The rods 21.2 do not have contact with the straps 13, but on the contrary, they are guided at their ends to the inner side 13.1 of the straps 13 in order to have the greatest possible working width. In contrast to rods 21, rods 21.2 do not require forging, and can be cut to the exact length from a roll, that is, they can be easily produced.
    [0026] [0026] Since the fastening areas 21.1 of the rods 21.1, shown in a running direction of the belts 13, have only a narrow extension, additional shoulders 25 can be provided on the upper side of the belts 13, diametrically opposite from the shoulders 19. These lugs 25 are used to protect the extreme regions 21.1 of the rods 21 that are attached to the straps 13, and as well as to protect against noise when the straps 13 roll out of the support rollers 16 and deflection rollers 17.
    [0027] [0027] As the result of a rod 21 being connected in each case to two other rods 21.2, the division of rods 21.2 and 21 as a whole, is significantly less than the division x of shoulders 19. This guarantees on the one hand that the sugar cane sections delivered to the feeding point 11, on the upper guide 33 of the inclined conveyor 10, cannot fall through the openings between the stems 21 and 21.2, and, on the other hand, that the optimum cleaning force it is, however, achieved due to the fact that the impurities carried with the sugarcane sections are able to fall through the openings between the stems 21 and 21.2.
    [0028] [0028] The inclined conveyor 10 is positioned on a support arm 26 which is composed of steel profiles 27 which are welded and screwed together. The lower end of the support arm 26 is rotatably mounted on the chassis of the sugarcane harvesting machine 1 by means of a hinge bearing 28. For this purpose, the support arm 26 is pivotally connected to the along approximately half its length to a hydraulic unit 2 9 on each side, and its other end is pivoted, articulated, the sugar cane harvesting machine 1. By activating the hydraulic unit 29, the support arm 26, as a whole, can be articulated, that is, fixed at a flat or inclined angle, on the articulation bearing 28.
    [0029] [0029] The deflection wheels 15 of the inclined conveyor 10 are configured as individual wheels, that is, they are not connected to each other by an axle, as shown in Figure 3. Each of the deflection wheels 15 is individually mounted rotatingly on a side support plate 30 of the support arm 26.
    [0030] [0030] As described above, the inclined conveyor 10 is driven by the driving wheels 14 provided at the discharge end 11 of the inclined conveyor 10. The drive device (not shown) of the driving wheels 14 engages with the openings 20 between the shoulders 19 in a positive fitting manner, therefore, forcing the belts 13. Forcing this, the lower driver 24 of the inclined conveyor 10 extends downwards from the driving wheels 14 to the deflection wheels 15. From hence, the upper driver 33 extends upwardly back to the driving wheels 14. The inclined conveyor 10 is supported in its circulation path by support rollers 16, the upper driver 33 rolling off the support rollers 16 through the shoulders 19 , and the lower driver 24 rolling off the support rollers 16 through the shoulders 25.
    [0031] [0031] The inclined conveyor 10, seen along its entire length, has sections with different inclination angles. In the area of the feed end 18 the inclined conveyor has a first section with a flat tilt angle, and then deflected in the deflection rollers 17, continuing to a more elevated mid-section. In addition, the deflection rollers 17, which pass the inclined conveyor 10 into a third section once again having a smaller tilt angle, are provided at the end of the middle section.
    [0032] [0032] During the operation of the sugar cane harvesting machine 1, through the collection funnel 8 the sugar cane sections fall on the stems 21 and 21.2 of the upper director 33 in the area of the feed end 18 of the inclined conveyor 10, which, as a whole, form a screening and support base. Impurities, such as soil, leaves, etc., which are transported with the sugarcane sections, and which have not yet been removed by the first extractor 9, can fall through the openings between stems 21 and 21.2, and thus being sifted in a way of saying. It is advantageous that the inclined conveyor 10 is completely open on the side in the area of the feed end 18 between the upper driver 33 and the lower driver 24, as shown in Figure 2, so that the sieved impurities are not able to just fall downward, but also migrate laterally. It is not possible for plant residues to be rolled over the deflection wheels 15, since, as described above, the deflection wheels are not connected by an axis.
    [0033] [0033] To prevent the sugar cane sections carried by the inclined conveyor 10 from being able to roll down on the rods 21 and 21.2, in particular in the inclined median section of the inclined conveyor 10, carriers 31, made of a polymer abrasion resistant and which carry the sugarcane sections along the top, are attached to the stems 21 and 21.2.
    [0034] [0034] In order to prevent the sugar cane sections supported on the upper driver 33 of the inclined conveyor 10 from falling on the side, on both sides of the upper driver 33 side plates 32 which together with the upper driver 33 form a U-shaped transport channel.
    [0035] [0035] The cleaning effect of the inclined conveyor 10 is further enhanced due to the belts 13 of the inclined conveyor together with its shoulders 19 in motion on the support rollers 16, thus generating vibrations that are transmitted from the belts 13 to the rods 21 and 21.2.
    [0036] [0036] At the discharge end 11 of the inclined conveyor 10, the sugar cane sections transported fall in free fall in a collection car. Due to the excellent cleaning effect of the inclined conveyor 10, as described here, the second extractor 12, illustrated in figure 1, can be dispensed with, or can be connected only as needed.
    [0037] [0037] It can be seen that the invention was carried out on a sugarcane harvesting machine having an inclined conveyor that transports sections of sugar cane from the harvesting machine inside a collection car and has, at least two traction mechanisms which extend parallel to each other and have continuous loaders, and which circulate on upper driving wheels, and lower deflection wheels which are jointly driven and located in the feeding area of the cane sections. sugar. The sugarcane harvesting machine of this type has been configured in such a way that, according to the invention, its inclined conveyor has a long service life with little maintenance and, at the same time, that the cane harvesting machine sugar works silently and in an energy efficient way with a high cleaning effect. As established here, this was achieved, for example, by the fact that the continuous traction mechanisms are configured as belts 13 made of reticulated polymer fabric with reinforced layer, and shoulders 19 positioned at a distance from each other, being positioned on the lower side of the belts to be forced into force through the driving wheels 14. The belts 13 are connected to each other by a plurality of transverse rods 21, which as a whole, form a sieving base and support base, and the deflection 15, which are driven together are configured as individual wheels.
    [0038] [0038] Although this invention has been described as having a preferred design, it should be understood that it is capable of further modifications, and the uses and / or adaptations of the invention and, in general, following the principle of the invention and including such modifications of the present disclosure as occurring within known or customary practice in the art, to which the invention relates, and as may be applied to the central features previously established, and within the scope of the invention.
