Definitions
- the invention relates to a haulm topper for an agricultural machine, in particular for processing potato plants, with a frame and at least one shaft that can be driven by a drive element of the haulm topper and on which a plurality of impact elements are arranged.
- the shaft is mounted on the frame.
- the invention further relates to an impact belt that can be used in such a haulm topper and to an agricultural machine with a haulm topper.
- the parts of the plant above the surface of the earth can be killed off a certain time before harvest. This will, for example, improve storage capacity.
- the haulm i.e. the part of the root crop above the surface of the earth
- DE 495 488 C discloses the use of a tine wheel which rotates around a shaft running lengthwise in the direction of travel, by which the haulm is knocked off and deposited between the ridges.
- the haulm toppers used can cause the root crop to sprout again, which prevents the plant or the parts of the root crop in the soil from ripening, especially in the case of potato tubers.
- Root cutters are used for this purpose, but these are difficult to use due to the altitude of the potatoes not always being known and can lead to losses due to unwanted damage to the root crops.
- a haulm topper according to the invention according to the preamble of claim 1 is characterized in that at least some of the striking elements are designed as flexible striking belts. Surprisingly, it has been shown that the forces transmitted to the foliage by the striking elements, which are designed as flexible striking belts, are distributed over a much larger area. The foliage is less or not at all beaten off or separated from the rest of the root crop. Instead, the foliage is only beaten so that the surface of the stems, in particular the epidermis, splinters and frays over a much larger area.
- the waxy outer layer is scraped off and the water-bearing areas of the plant, the xylem, are increasingly damaged and exposed lengthwise along the stem, which leads to significantly greater evaporation of the water contained in the foliage.
- the foliage dies faster and more permanently and the plant no longer or hardly sprouts again.
- the ripening of the root crops is improved.
- the foliage is not cut off as completely as possible, but rather the stems of the foliage are frayed over as large an area as possible, ie in particular in the longitudinal direction of the stems, in order to bring about a rapid drying of the foliage still connected to the part of the potato plants located below the surface of the soil.
- the striking elements are designed as flexible striking belts.
- the striking elements designed as flexible striking belts are advantageously those which work on the plants arranged on the ridge when striking potato leaves.
- the beating belts are provided with a surface made of rubber, polyurethane or another plastic that has a material-specific roughness. The beating belts rub more intensively against the epidermis of the stems, causing damage to the epidermis over larger areas. The epidermis or an outer wax layer is particularly scraped off by the beating belts, even to the point of damaging the xylem.
- any kinks that may occur in the plant result in elongated damage to the outer surface of the foliage, particularly in the longitudinal direction of the stem.
- the removal or damage of the epidermis causes the foliage to dry out much more quickly, which in turn effectively prevents new sprouting, as described above.
- the ripening of root crops, particularly potato tubers, can be controlled much more precisely than is known in the prior art.
- the object is also achieved by a method for beating haulms, in particular for beating potato haulms, wherein the haulms are beaten with a haulm beater according to the invention, the shaft of which is preferably guided across a row of haulms transversely to the latter, wherein a plurality of beating elements designed as flexible beating belts are arranged on the shaft driven by a drive element, which move along the stalks of the haulms during beating in such a way that they fray in the longitudinal direction.
- the beating belts rest on the stalks.
- the stalks are deflected from a side which is transverse to the longitudinal direction of the respective beating element and at an angle to the direction of rotation.
- the stalks can rotate at least slightly around their own axis. roll on the inclined side, which connects a front side in the direction of rotation with a rear side in the direction of rotation, so that a larger surface area of the stem comes into contact with the surface of the striking element.
- a belt is understood to mean striking elements that are flexible in the traditional sense and are designed to be so flat that their extension in the direction of their flat design is significantly greater than in the direction of their thickness.
- the striking belts are not made from flat metal rods or strips.
- Beater belts are particularly flexible when they are made at least predominantly from plastic or rubber materials and/or when harder materials are used, these form correspondingly flexible composites, e.g. braided or fabric structures.
- they are preferably elongated, i.e. the extension of a beater belt from its start fixed to a drive shaft to its end is greater than the extension transverse to it. This extension defines the longitudinal direction of a beater belt.
- Metal striking elements are not considered to be inherently flexible within the meaning of the invention.
- the striking elements can be attached to the shaft in a movable manner, for example via joints, or can be firmly clamped in such a way that they derive their mobility solely from their flexibility. According to a further development of the invention, such striking elements can nevertheless be used in addition to the flexible striking belts designed impact elements are arranged on the shaft and complement the impact belts, especially in areas intended to raise existing weeds between dams in the so-called dam valley.
- a haulm topper according to the invention is provided on at least one shaft exclusively with impact elements designed as flexible impact belts.
- Combinations of conventional steel flails and flexible impact elements can also be arranged on a shaft in a staggered manner in its circumferential direction.
- the impact elements which are designed as impact belts, are arranged on a drivable shaft.
- Such an arrangement also includes an arrangement in which, for example, a cylinder or similar part which receives the shaft and on which the impact elements are arranged is attached to the shaft.
- the impact elements are preferably attached to or on the shaft in particular via at least one fastening device.
- the shaft is aligned transversely to the intended direction of travel of the haulm topper, so that the haulm can be covered over a certain width.
- the longitudinal direction of the shaft is the direction in which the axis of rotation of the
- the stem receiving profile is designed in particular in the form of at least one notch and/or indentation in the end.
- a notch or indentation can be made by punching out part of the front side of the end of the whipping belt. Such punching can also be used to cut a belt element manufactured to a longer length. While a notch that tapers towards the beginning of the whipping belt causes increased crushing of the plant stem and thus tends to cause it to fray, By creating an indentation, both a bruise and a hidden scraping of the epidermis can be achieved.
- the stem receiving profile comprises only one notch or has an indentation at the end of the respective impact element, at least if this is not wider than 10 cm, so that the other end areas of the impact element still have sufficient strength, which is lower due to the belt material than in the case of metallic impact elements known from the prior art.
- a dam profile is defined as an edge profile through which the striking elements follow the contour of the earth dam.
- it is a profile which, in a plan view of a striking belt lying flat on the ground, has a shape that is beveled on one side or tapered on one side. This makes it easier to reach the areas of the foliage that are on the sides of a dam designed, for example, as a potato dam.
- a striking belt provided with a beveled end can also have a profile at this end for receiving a stem.
- a dam profile is formed at least by the fact that impact belts are provided on a shaft which extend at different distances from a rotation axis of the shaft.
- the shaft can be provided with several groups of beater belts with a dam profile, so that the shaft has at least two groups of shorter beater belts in order to be able to travel along at least two dams at the same time or to process the weeds arranged on them.
- all impact elements arranged next to one another on a shaft are provided with a stem receiving profile at the end, wherein the lengths of the impact elements are adapted to the contour of the terrain to be driven over, in particular that of a potato ridge.
- a beating belt is particularly rectangular, whereby this applies at least to those areas that do not have a stem receiving area. It goes without saying that the corners of such a rectangle can have rounded areas that are due to the manufacturing process. Viewed in such a cross-section, the height of the structure or the height of the rectangle (as well as the choice of material) determines the desired flexibility or strength of the beating belt, so that it can be adapted to different plants.
- the impact belt is advantageously fixed on the shaft side, e.g. clamped in, so that the mobility comes from the belt itself.
- the torque acting on the belt can be determined more precisely than in the prior art, in which the impact elements can also be connected in an articulated manner.
- the belts there is a preferred direction for the belts, so that when the shaft starts, part of the forces are not initially directed towards the alignment of the impact elements.
- the haulm topper is provided with at least one beating belt which, when viewed in a cross-section transverse to its longitudinal direction, has a front, first side in the direction of rotation, which is connected via a side that is inclined to the direction of rotation to a side that is rear in the direction of rotation, i.e. with a surface normal pointing against the direction of rotation, in particular which is wider than the front side.
- the transition between the front and side, inclined side forms a corner or edge that is advantageous for shredding the haulm.
- the inclined side also applies an additional impulse to the affected stalk, so that it rolls at least slightly on the (side) side of the beating belt and the area of the stalk that comes into contact with the belt is increased.
- the length of the front side is preferably between 40% and 70% of the length of the rear side, so that at least one side is inclined to the direction of rotation, i.e. a surface normal of the inclined side is angled to the direction of rotation at an angle > 0° and ⁇ 90°, in particular at an angle > 10° and ⁇ 80°.
- the impact elements are pre-bent so that a respective impact element stretches longitudinally against its bend during operation due to centrifugal force.
- the respective impact element is pre-bent and curved, particularly in the direction of rotation.
- the end of the respective impact element would be in front of the shaft-side connection in relation to the direction of rotation, regardless of any force effects due to centrifugal and weight forces.
- the material of the impact belt which is usually rubber or plastic and at least elastic, is compressed on the side that is at the rear during operation, which leads to a slight stiffening of the rear area of the impact element.
- the front side in the direction of rotation has a width of 5 mm - 15 mm, while the rear side has a width of 12 mm - 24 mm.
- the thickness in the circumferential direction can be 7 mm - 16 mm. The width can be adjusted to the width of the haulm to be processed, so that younger haulms are processed with narrower and older haulms with wider impact elements.
- a respective impact element has a trapezoidal contour in a section transverse to its longitudinal extent, which is preferably between 200 mm and 400 mm.
- At least one oblique side and in particular both oblique sides of a respective impact element form an angle of between 100° and 120° with the front side, which has proven to be advantageous in the course of a large number of tests and contrary to previous assumptions with larger angles.
- each impact belt is formed by an EP rubber fabric belt and can thus be easily manufactured following known production processes.
- a part of the impact elements has a trapezoidal cross-section and another part of the impact elements a different cross-section.
- all cross-sections are trapezoidal.
- an impact belt has a reference elongation at 10% of the breaking force of ⁇ 3.0%, preferably less than 2.5%, measured according to DIN 22109.
- the impact belt(s) also have a Shore A hardness between 50 and 70, in particular between 55 and 60.
- one or more impact belts are provided with a surface that has an abrasion resistance, measured according to DIN ISO 4649 iA, of less than 150 mm2 .
- At least one of the edges of individual or multiple beating belts which come into contact with the weeds to be beaten during operation and which form the contour of the beating belt is at least partially designed to be wear-resistant in such a way that the material forming the respective edge is more abrasion-resistant than other material forming the beating belt.
- impact elements can have a common base for easier attachment of the impact elements to the shaft.
- a base is in particular formed in one piece with several flexible impact elements.
- a fabric insert that absorbs tensile forces of in particular at least three impact elements and particularly preferably of the five or six impact elements extends into the base formed in one piece with these, so that a more secure attachment of the impact elements to the shaft is achieved.
- a single impact belt can be connected to the shaft via one or more and in particular a maximum of four chain links in order to support any rotational movement of the impact element, whereby due to the alignment of the chain links in the direction of rotation or transversely thereto, a return to the starting position with a first side that is shorter in the direction of rotation is promoted.
- the width of an impact element can vary repeatedly over its longitudinal extent; in particular, the front corners of the impact element can form a wave pattern, resulting in offset impact areas over the length of the stem to be processed, thus improving the shredding.
- a plurality of striking elements in the form of striking belts are distributed in particular evenly around a shaft in the circumferential direction. In particular, these are fastened to the shaft via one or more fastening devices.
- a plurality of striking elements designed as striking belts are fixed next to one another in the longitudinal direction of the shaft at the same circumferential position.
- a plurality of clamping devices are arranged for this purpose around the shaft in the circumferential direction, via which a plurality of striking belts are fixed in the circumferential direction around the shaft and in particular at the same circumferential position.
- striking belts arranged one behind the other can thus be arranged, for example, at 12 o'clock, 3 o'clock, 6 o'clock and 9 o'clock by means of respective fastening devices.
- the impact elements in the circumferential direction of successive rows are preferably arranged offset in the longitudinal direction of the shaft.
- the successively offset rows are arranged arranged beater belts are at least partially provided with stem-receiving profiles.
- these are the beater belts that are intended to capture the haulm on an upper ridge contour, where it mainly grows in potato plants.
- At least three and in particular four rows of impact elements arranged side by side are provided, evenly distributed over the circumference of the shaft, which ensures optimum capture of the haulm at the typical working speeds of the haulm topper.
- the speed of the shaft or shafts of a haulm topper according to the invention can be reduced so that they can now be operated in a way that is more energy-efficient and less wear-intensive.
- the speed of a haulm topper according to the invention is therefore advantageously between 750 and 1100 rpm for lengths of the impact belts of preferably no more than 20 cm, and between 600 and 1300 rpm for lengths of no more than 40 cm. This results in peripheral speeds of the ends of the impact elements which, at around 14 m/s to 20 m/s, are around 50% lower than those known from the prior art.
- the haulm topper according to the invention is controlled in such a way that a maximum of fiberization is achieved for each haulm.
- the height of the shaft and/or The distance between the beater belts is relevant for the weed-specific shredding.
- the length of the beater belts can also be selected depending on the plant to be worked on in order to achieve the longest possible shredding.
- At least one of the striking elements is provided with at least one particularly elongated striking elevation on its surface.
- a striking elevation is a material thickening that leads to a greater thickness of the material and that results in an increase in the surface area of the striking belt. The striking forces are thus transferred to the surface of the plant over an even greater part, which leads to an improved effect of drying out the plant.
- Elongated striking elevations can also be referred to as webs or ribs, which increase the surface area of the striking belt.
- the striking elevation of a striking belt designed as a striking rib, extends transversely to the longitudinal extension of the striking element, so that the striking rib preferably extends parallel to the shaft axis over the entire width of a striking element.
- a preferred bending direction can be specified by means of targeted, particularly rib-like elevations and thickenings of the whipping belt, so that the whipping belt can adhere even better to the plant and
- the area of induced kinks can tear and then fray more easily.
- a fabric insert This extends over the entire length and width of the striking element, so that the areas of the striking element that are present in the shaft and are fixed there are also provided with a fabric insert.
- Such a fabric insert is preferably a wireless fabric.
- the haulm topper is preferably provided with two shafts that can move relative to one another, with the shaft that is additional to the first shaft also having a plurality of additional impact elements in the form of impact belts.
- These impact belts can of course be designed like the impact belts described above or below and can also be attached in the same way.
- the shafts are arranged in particular on the same frame and are preferably driven by their own drive elements. These drive elements can be their own motors, e.g. their own hydraulic motors, or they can be drive elements branched from a common central drive.
- a haulm topper can be provided with two shafts arranged one behind the other in the direction of travel, each with a respective beating belt, wherein the shafts can rotate in opposite directions.
- a haulm topper according to the invention can be provided with an additional unit for raising haulm, e.g. in the form of a star roller, which is arranged upstream of at least one shaft with impact elements in the direction of travel.
