Definitions

  • the invention relates to a cutting tooth for a harrow, in particular for a cutting wheel of a trench cutter according to the preamble of claim 1.
  • a cutting tooth has a tooth root for receiving in a holder of the harrow and at least one head cutting element arranged on the main cutting element for processing soil material.
  • Such cutting teeth are for example from the DE 297 20 261 U1 and the DE 87 15 141 U1 known and used in civil engineering trench wall milling for the production of slot walls.
  • the cutting teeth can be used in particular in wheel milling, where they are arranged on the lateral surfaces of the cutting wheels.
  • the cutting wheels are set in rotation and lowered into the ground, wherein the cutting teeth break up and loosen the soil material present on the cutting wheels so that they can be sucked off, for example by means of a pump, and / or processed into a suspension.
  • Milling wheels for tillage are often constructed disc-like over an underlying, in particular cylindrical, wheel body, wherein the disc axis coincides with the axis of rotation of the cutting wheel. In the disc areas of the cutting wheel, the cutting teeth and optionally their holders are arranged.
  • the known cutting teeth have a shaft-like tooth root for receiving in the Fräs leopardhaltern. At an upper edge of the cutting tooth, a carbide cutting edge for cutting the upcoming soil is provided.
  • the width of the cutting tooth cutting edge is chosen above all depending on the soil to be worked. For harder rock material a narrower cutting width is generally advantageous. By reducing the cutting width, a higher contact pressure can be achieved with otherwise identical milling design, which increases the milling progress, especially in hard geologies. There are therefore known cutting teeth, in which the cutting edge is formed narrower than the underlying end face of the tooth root.
  • each angular position requires its own milling tooth type designed for this angular position.
  • the carbide cutting edge is offset depending on the tooth inclination on the right or left side with respect to the middle of the cutting teeth, whereas with non-inclined cutting teeth the cutting edge is arranged centrally.
  • the object of the invention is to provide a particularly economical and versatile cutting tooth, which is particularly suitable for harder soil geologies.
  • the cutting tooth according to the invention is characterized in that, in order to widen the processing cross section of the main cutting element, at least one further recutting element is provided on the head side on the tooth root, which has a different cutting edge design compared to the main cutting element.
  • a basic idea of the invention can be seen in the fact that the entire processing width of the cutting tooth is not made available by a single cutting element, but rather to provide a plurality of cutting elements on the tooth head, which are laterally offset from one another transversely to the milling direction. According to the invention, a plurality of different types of cutting are combined for clearing soil material over the entire processing width. Experiments have shown that with such a cutting edge design compared to previously known types of teeth with a single cutting edge, especially in harder soils, higher milling progress can be achieved.
  • a cutting tooth can be provided with a main cutting element which is narrower with respect to the holder and / or the tooth root, in order to be able to machine harder soils and thereby achieve a sufficient milling progress.
  • the main cutting element can be attached, for example, frontally centered on the tooth root.
  • additional trimmers are provided according to the invention, which can be arranged in particular symmetrically to the main cutting element. These reamers broaden the overall processing cross section of the cutting tooth. Therefore, with a small main cutting element and thus good milling progress, a total milling width greater than the width of the tooth root and / or its holder is achieved.
  • the holders and the clearing areas arranged between the cutting wheel disks can be reliably cut free with good milling progress without the inclination of the cutting teeth being required for this purpose.
  • the invention thus makes it possible to provide only a single Fräs leopardtyp for a large part of the tooth positions on the cutting wheel, which significantly minimizes the cost of spare parts and also significantly reduces the risk of faulty dental installation.
  • the invention makes it possible to equip with a tooth stock almost the entire cutting disc.
  • the main cutting element has at least one wedge-shaped cutting edge.
  • the cutting edge of the main cutting element then has a longitudinal extension and can also be referred to as a linear cutting edge.
  • a wedge-shaped cutting edge is particularly well suited for cutting the upcoming soil, especially on hard soils.
  • the recutting element has at least one pin cutting edge.
  • a pencil cutting edge can be cone-shaped, wherein the cone can, for example, have a round or oval base surface.
  • a pencil cutting edge is particularly well suited for the final cutting of the soil material already loosened by the main cutting element.
  • the arrangement of an additional pin edge due to their small footprint reduces the total contact pressure of the trench wall cutter only slightly, so that the milling progress of the main cutting element is at most slightly affected.
  • Pen cutting also comparatively inexpensive and require a relatively small soldering surface on the tooth root.
  • the pencil edge can also be referred to as a point cutting edge. For a good milling progress, it is usually advantageous that the main cutting element has a more aggressive cutting edge compared to the Nachschneidelement.
  • the tooth root is, in particular together with receptacles for the cutting elements, advantageously made of cast metal.
  • the Nachschneidelement has a round shank chisel.
  • a round shank chisel typically has a shank and a cross-sectionally larger head arranged thereon, on the end of which a hard metal pin is provided.
  • the round shank bit can be designed as a simple cutting pin.
  • At least one receiving sleeve in particular with a circular or elliptical inner cross section, is provided on the tooth root, in which the at least one regrooving element, preferably interchangeable, is arranged.
  • the main cutting element is aligned for root removal in a main cutting direction on the tooth root.
  • the main cutting direction can also be referred to as a milling direction and in particular represents the direction in which the cutting tooth due to the pure rotational movement of the cutting wheel moved tangentially.
  • Perpendicular to the direction of milling extends the feed direction of the cutting tooth, which corresponds in particular to the radial direction of the cutting wheel.
  • the Zahnfußlticiansachse runs at least approximately parallel to the feed direction.
  • the main cutting element is arranged ahead of the Nachschneidelement in the main cutting direction leading the tooth root.
  • the main cutting element is provided at the front side, at the end face facing the adjacent soil material, at the tooth root. In particular, it can protrude at least in sections over the end face of the tooth root in the main cutting direction.
  • the main cutting element is preceded by a cutting support region arranged at the top end on the tooth root, on which in turn the recutting element and optionally its receptacle are provided.
  • a particularly high contact pressure and thus a particularly good Fräsfortrough can be achieved in that the cutting width of the main cutting element is smaller than the width of the tooth root.
  • the cutting width of the main cutting element can generally vary over its height.
  • the dimension of the removal cross section of the main cutting element perpendicular to the main cutting direction and perpendicular to the feed direction of the cutting tooth can be understood as the cutting width.
  • a further advantageous embodiment of the cutting tooth according to the invention is characterized in that, when viewed in the main cutting direction, the recutting element protrudes laterally over the main cutting element and in particular over the tooth root.
  • the Nachschneidelement protrudes on both sides beyond the main cutting element or the tooth root, for which purpose at least two recutting elements can be provided.
  • Such an arrangement allows a safe free cutting of the tooth root and possibly arranged on the cutting wheel spaces for researcherrimplantation.
  • a protrusion protruding transversely to the direction of advance and / or the longitudinal axis of the tooth root is understood to mean a lateral protrusion.
  • a cutting tooth with a particularly reliable free-cutting function results from the fact that at least two recutting elements are provided. Suitably, when viewed in the main cutting direction on both sides of the main cutting element each a Nachschneidelement is arranged.
  • a cutting tooth that is particularly suitable and thus robust for receiving the operating forces is obtained in that the main cutting element, the recutting elements and in particular the tooth root are constructed with mirror symmetry. The plane of symmetry is suitably in the main cutting direction.
  • the milling progress can be further improved by the fact that the main cutting element has at least one longitudinal cutting edge running transversely to the main cutting direction.
  • the longitudinal cutting edge is suitably followed by two secondary cutting edges in a V-shaped manner. While the longitudinal cutting edge suitably extends approximately in the feed direction, the secondary cutting edges suitably extend transversely to the feed direction from the cutting tooth center to the longitudinal sides of the tooth root.
  • two or more slitters are provided parallel to each other.
  • the cutting tooth according to the invention can also be used as a folding tooth, which is tilted in response to the rotation angle of the cutting wheel to cut free axially displaced bottom regions.

  • a milling tooth according to the invention can also be used as a so-called caliber tooth, which is arranged on the axially outer outer disks of the cutting wheel in order to cut free the outer region of the cutting wheel, that is to say its end surfaces.
  • the recutting element is preferably arranged only on one side with respect to the main cutting element.
  • at least one further cutting element is suitably arranged on the tooth root on the side of the cutting tooth on which the recutting element is also located.
  • the further cutting element is constructed identically with the recutting element and in particular has a pin cutting edge.
