    Agricultural ruq shape arrangement. tractor and use thereof
    The present invention relates to an agricultural rug-forming device according to the preamble of the first claim.
    The present invention also relates to the use of the agricultural back forming device.
    Such agricultural rugging devices are already known to those skilled in the art. United States Patent No. US2226575, for example, describes an agricultural back-forming device for forming a back along a direction of travel with an adjacent front. The agricultural back-forming device comprises a back-forming element for forming ridges and adjacent furrows in front, a separate dam-forming element for forming dams traversing the front, and an actuator with which the dam-forming element is equipped for displacing the dam-forming element between a first and a second position. The dam-forming element is arranged such that it moves along a front formed by the back-forming element and is movable between a first and a second position, the dam-forming element in the first position being arranged to scrape soil together in the furrow in order to obtain a forming a dam, the dam-forming element in the second position being adapted to be moved over the previously formed dam. The dam-forming element is tiltably mounted on the rest of the back-forming device and comprises a plate-shaped scraping element, the surface of the mold being oriented substantially transversely of the back. A mechanical sensor element is mechanically coupled to the dam-forming element in such a way that when the dam reaches a predetermined height, the dam presses against the mechanical sensor element, which in turn drives the dam-forming element from the first to the second position. When the mechanical sensor element is no longer in contact with the dam, it returns to its starting position, simultaneously driving the dam-forming element from the second position back to the first position, such that a new dam is formed.
    Such agricultural back-forming devices, however, have the problem that when they are driven at relatively high speeds, there is a risk that the mechanical sensor element is no longer displaced by the formed dam, and therefore no longer drives the dam-forming element correctly. Consequently, the dams in such situations are no longer shaped as desired. The speed with which the agricultural back-shaping devices can be driven is therefore rather limited.
    Additional agricultural devices are known, for example, from GB1450650, US4257487, US4303129 and US2226575.
    It is therefore an object of the present invention to provide an agricultural back forming device that can be driven at higher speeds without, for example, reducing the number of desired dams in the front.
    This object is achieved with the agricultural back-shaping device according to the characterizing part of the first claim.
    The actuator is for this purpose a fluid-driven actuator.
    It has been found that fluid-driven actuators, such as for example hydraulic and / or pneumatic actuators, can drive the dam-forming element between the first and the second position without being dependent on the properties of the dam formed, for example without the need for mechanical sensor means for registering the height of the dam, but instead allowing the dam-forming element to be moved based on the desired frequency of the dam along the length of the furrow. The desired frequency of the dams over the length of the furrows, for example expressed in number of dams per unit of length, can then be coupled, for example, to the current speed of the agricultural back-shaping device, for example by multiplying the speed of the agricultural back-shaping device by the desired frequency of the dams along the length of the furrow, such that the number of times that the driver has to move the dam-forming element from the first to the second position, the drive frequency, can be determined.
    It has also been found that fluid-driven drivers enable high drive frequencies that are much more difficult to achieve with the help of mechanical configurations as described above. Moreover, it has been found that fluid-driven actuators make it possible to transfer relatively large forces, such that relatively heavy bottoms can also be processed.
    U.S. Patent No. US4257487 describes an agricultural back-forming device provided with a fluid-driven driver, but the back-forming element and the dam-forming element are not separated from each other and have the shape of a single element arranged to be moved between a first and a second position by the fluid-driven driver. In such an embodiment, however, the dam-forming element should be relatively large and heavy, such that it becomes difficult to achieve high driving frequencies.
    According to preferred embodiments of the present invention, the dam-forming element is tiltably mounted on the rest of the back-forming device. It has been found that such a mounting of the dam-forming element increases the capacity of the dam-forming element to function at relatively high driving frequencies.
    According to preferred embodiments of the present invention, the dam-forming element comprises a plate-shaped scraper element, the surface of the mold being oriented substantially transversely of the back. Such a plate-shaped scraping element has been found to make relatively high driving frequencies possible with relative ease, since it can be made relatively light.
    According to preferred embodiments of the present invention, the plate-shaped scraper element is tiltably mounted to the rest of the back-forming device and is attached to the actuator. It has been found that such a configuration increases the capacity to use relatively high drive frequencies.
    According to preferred embodiments of the present invention, the back-forming element is adapted to form at least two backs, with a front next to and between the two backs, the dam-forming element being arranged in such a manner with respect to the back-forming element that in the first ground position is scraped together in the furrow to form a dam that connects the ridges and crosses the furrow between the ridges. It has been found that such embodiments make it possible to form dams in successive furrows that provide a better seal between two adjacent ridges.
    According to preferred embodiments of the present invention, the actuator is a pneumatic actuator. Such a driver makes even more improved drive frequencies possible. Although pneumatic actuators are preferred, it has been found that hydraulic actuators make it possible to transfer relatively large forces, such that heavier bottoms can also be worked.
    According to preferred embodiments of the present invention, the dam-forming element is resiliently mounted on the back-forming element. Such a device makes it possible to reduce the weight of the dam-forming element even more, since the relatively large forces acting on the dam-forming element can be absorbed at least partially by the spring device.
    According to the present invention, a soil releasing agent, for example, a soil penetrating element which, in use, protrudes at least partially into the soil, is provided between the back-forming element and the dam-forming element along the direction of movement, for releasing the soil after a back and an adjacent were formed. It has been found that such a soil releasing agent reduces the forces acting on the dam-forming element, making it possible, for example, to reduce the weight of the dam-forming element even more, which enables even more increased drive frequencies and also makes it possible to use heavier soils. edit.
    According to preferred embodiments of the present invention, the bottom penetrating element is resiliently mounted on the back-forming element. Such a device makes it possible to further reduce the relatively large forces acting on the soil penetrating element, since these can be absorbed at least in part by the spring device.
    According to preferred embodiments of the present invention, the agricultural back-forming device comprises at least one spring element, preferably of sheet metal, which connects the soil-penetrating element and / or the dam-forming element to the back-forming element. Such a device makes it possible to further reduce the relatively large forces acting on the soil penetrating element and / or the dam-forming element, since these forces can be absorbed at least in part by the spring device.
    The invention also relates to the use of the agricultural back-forming device according to the invention.
    According to preferred embodiments of the present invention, the dam-forming element is driven from the first to the second position as a function of the speed of the agricultural back-forming device. According to further preferred embodiments of the present invention, the agricultural back-shaping device comprises for this purpose, for example, speed registration means for registering the speed of the agricultural back-shaping device, connected to a processing unit which calculates the drive frequency for the driver in dependence on the desired number of dams along the length of the furrows, which is expressed, for example, in number of dams per unit length, the processing unit being connected to the actuator and causing the actuator to move so that the actuator moves the dam forming element the desired number of times from the first to the second position, and the desired number of dams is formed along the length of the front.
    According to preferred embodiments of the present invention, the agricultural back-forming device is used to form ridges with dams between them. It can be used in agriculture for any agricultural product (such as, for example, potatoes, carrots or any other root vegetable, maize, asparagus, smallanthus sonchifolius, manihot esculenta, etc.) grown in or on ridges, in particular on hilly fields that are subject to erosion.
    The invention will be further elucidated with the aid of the following description and the enclosed illustrations.

    Figure 1 shows a side view of a preferred embodiment of the agricultural back-shaping device according to the present invention.
    The agricultural back-shaping device 1 is adapted to form a back 15 along a direction of travel 2 with an adjacent front 16. The agricultural back-shaping device 1 comprises a back-forming element 3 for forming backs 15 and adjacent front 16 in soil. The back-forming element 3 may, for example, take the form of at least one ironing board 13, for example in metal, such as steel, preferably stainless steel, preferably two ironing boards 13, as shown in Figure 1. In such a configuration, for example, it is back-forming element 3 adapted to form at least two ridges 15, with one in front of 16 next to and between the two ridges 15. The back-forming element 3 can for instance take the form of a plow provided with the ironing board 13. The configuration of the back-forming element 3 can, however, be determined by the person skilled in the art, depending on the desired characteristics of the agricultural back-forming device 1.
    The back-forming element 3 is arranged to be pulled through soil in such a way that ridges 15 are formed.
    The agricultural back-shaping device 1 is furthermore provided with a dam-forming element 4, separated from the back-forming element 3, for forming dams which cross the crossings formed by the back-forming element 3 transversely. The dam-forming element 4, which is divided into Figure 1, comprises a plate-shaped scraper element 8, the surface of the mold of which is oriented substantially transversely of the ridge 15. The plate-shaped scraper element 8 can be made of any material that is considered suitable by the person skilled in the art, such as for example metal, for example steel, preferably stainless steel. The shape and dimensions of the plate-shaped scraper element 8 can be determined by those skilled in the art, depending on the desired shape and dimensions of the dam, taking into account the forces acting on the plate-shaped scraper element 8, depending on, for example, the bottom in which it will be used and / or the speed at which it will be driven through the soil.
    The dam-forming element 4 is arranged such that it moves along a front 16 formed by the back-forming element 3 and is displaceable between a first 5 lowered and a second 6 raised position. More preferably, the dam-forming element 4, for example due to a suitable material and suitable dimensions of the dam-forming element, is arranged with respect to the back-forming element 3 such that in the first lowered position 5 earth is scraped together in the front 16 in order to obtain a dam that connects the ridges 15 and which crosses the furrow 16 between the ridges 15. Figure 1 shows, for example, that the dam-forming element 4, more in particular the plate-shaped scraping element 8, is positioned for this purpose, for example, between the two ironing boards 13 along a direction which is substantially transverse to the direction of movement. Figure 1 further shows, for example, that the dam-forming element 4, more in particular the plate-shaped scraping element 8, is for this purpose positioned, for example, behind the back-forming element 3, more particularly behind the ironing boards 13, along the direction of travel 2.
    The height at which the dam-forming element 4 is positioned relative to the back-forming element 3 can be determined by the person skilled in the art, and depends, for example, on the desired height of the dam that one wishes to form.
    The dam-forming element 4 is shown in Figure 1 in the first position 5, and is adjusted in that position to scrape soil together in the furrow 16 to form the dam. The dam-forming element 4 is shown in Figure 2 in the second, raised position 6, and is adapted to be moved over the previously formed dam.
    As can be seen in figures 1 and 2, the dam-forming element 4, more in particular the scraper element 8, is tiltably mounted on the rest of the back-shaping device, and more particularly tiltably mounted on the rest of the agricultural back-shaping device 1 relative to of the back-forming element 3. Since the dam-forming element 4 and the back-forming element 3 are separated and the dam-forming element 4 can therefore be moved independently of the back-forming element 3 between the first 5 and the second 6 positions, the formation of ridges 15 and 16 when using the agricultural back-shaping device should not be interrupted when dams are to be formed. The dam-forming element 4, in particular the scraper element 8, is mounted on the agricultural back-forming device by means of a tilting axis 14.
    In order to move, in particular tilt, the dam-forming element 4, a damper 7 is provided on the dam-forming element 4, as shown in Figure 1, for displacing the dam-forming element 4 between the first 5 and the second 6 position. The actuator 7 shown in Figure 1 is attached to the scraper element 8, more particularly at a distance from the tilting axis 14, to a first end portion of the actuator 7, while a second end portion of the actuator 7 is attached to a part of the agricultural back-forming device 1 that is not arranged to be tilted.
    Figure 1 shows that the dam-forming element 4 and the actuator 7 are mounted on the mounting element 12, the second part of the actuator 7 being attached to the mounting element 12.
    As can be seen in figure 1, the dam-forming element 4 is preferably resiliently mounted on the back-forming element 3. Figure 1 shows that this was achieved by resiliently mounting the mounting element 12 on the back-forming element 3. Furthermore, Figure 1 shows that the agricultural back-forming device 1 comprises at least one spring element 11 for this purpose, preferably from sheet metal, with more preferably in the form of a piece of bent sheet metal as shown in Figure 1, which connects the dam-forming element 4 to the back-forming element 3.
    The mounting element 12 as shown in Figure 1 is a piece of sheet material, for example metal sheet material, which can be brought into the desired shape by bending, welding, bolting, etc.
    Figure 1 further shows that a soil-releasing means 9 is provided between the back-forming element 3 and the dam-forming element 4 along the direction of travel 2, for loosening the bottom after a back 15 and an adjacent front 16 have been formed. As shown, the soil releasing agent 9 preferably comprises a soil penetrating element 10 which protrudes into use at least partially into the soil. The bottom penetrating element 10 is preferably resiliently mounted on the back-forming element 3. To that end, the agricultural back-forming device 1, as shown in Figure 1, preferably comprises at least one spring element 11, preferably from sheet metal, more preferably in the form of bent sheet metal which connects the bottom penetrating element 10 to the back-forming element 3. In the embodiment shown in Figure 1, the bottom penetrating element 10 is an end portion of the bent sheet metal.
    The agricultural backing device 1 shown in Figures 1-3 is preferably mounted or arranged to be mounted on an agricultural tractor, as can be seen in Figure 4. The spring element 11 preferably connects the dam-forming element 4 and, if present, the soil-releasing agent means 9 resilient with the tractor, while the back-forming element 3 is mounted almost rigidly on the tractor. The agricultural back-forming device 1 can be arranged to be pivoted upwards between a first, bottom-penetrating position, in which the back-forming element 3, in particular the ironing board 13, is arranged to penetrate the bottom or to penetrate the bottom, and a second, non- soil penetrating position, in which the back-forming element 3, in particular the ironing board 13, is not adapted to penetrate the soil, so that the tractor can drive without working the soil, for example when driving to or from the cultivated or cultivated field.
    Although Figure 4 shows that the front 16 and the adjacent ridges 15 have already been formed at least partially in front of the tractor, this is not crucial for the invention, and the bottom can also be, for example, substantially unprocessed, for example substantially leveled.
    Furthermore, figure 4 shows that the agricultural back shaping device 1 is mounted on the rear of the tractor. However, this is not crucial to the invention, and the agricultural back-forming device 1 can also be mounted in front or to the side, depending on the use and the desired configuration.
