Definitions

  • the invention relates to a cutting wheel for a trench wall cutter with a drum-shaped hub, on the outer circumference of which plate-shaped tooth holders are arranged in at least one circumferential row, in which cutting teeth are releasably held for removing soil, according to the preamble of claim 1.
  • a generic milling wheel comes from the EP 2 685 007 A1 out.
  • This known milling wheel has ring segment-like tooth holders along several circumferential rows, which are attached to the drum-shaped hub axially offset from one another.
  • Each arcuate tooth holder has a large number of removal teeth, which have a different position relative to one another.
  • the individual removal teeth protrude to different extents from the tooth holder in order to cover as wide an area as possible of the existing soil with the cutting bodies on the individual removal teeth. This allows good soil removal to be achieved.
  • a milling tooth with a tooth base for receiving in a holder of a milling wheel and with a tooth head with a main cutting element is known.
  • One or more recutting elements with pin-shaped cutting edges are arranged in the area of the tooth base, offset backwards in the milling direction, with which even harder soil geologies can be processed.
  • the DE 87 15 141 discloses a trench wall cutter tooth in which the tooth head width approximately corresponds to the tooth root width.
  • the tooth head has a cutting edge with several hard metal plates;
  • the US 4,666,214 discloses an asphalt milling machine with milling teeth and a respective shaft structure which are arranged tangentially on the milling drum.
  • an asphalt milling machine is designed to remove hard asphalt materials close to the surface and is not suitable for creating a milling slot over many meters in cohesive layers of earth.
  • the JP S57 46611 also shows an asphalt milling machine comparable to that US 4,666,214 . What was said above applies accordingly.
  • the EP 2 597 205 shows a trench wall cutter with many types of cutting teeth, folding teeth with inclined tooth holders.
  • the tooth tip width roughly corresponds to the tooth root width.
  • the invention is based on the object of specifying a milling wheel for a trench wall milling machine, with which efficient milling is possible even with different soil layers.
  • the cutting wheel according to the invention is characterized in that at least one cutting tooth is provided with a tooth head extending transversely to both sides of the tooth root, that the tooth head has a lateral first head region and a lateral second head region, which extend in opposite directions from one another, and that At least two cutting bodies lying next to each other are arranged in each head area.
  • a basic idea of the invention is to provide a milling wheel with one or more T-shaped milling teeth in the circumferential direction when viewed from above, which have a transversely extending tooth head with several cutting bodies. This means that a larger width of the soil can be removed using a single milling tooth. This in turn makes it possible to reduce the number of necessary milling teeth and thus also the number of necessary tooth holders in a circumferential row and distributed over the milling hub. This significantly increases the free space between the milling teeth and the adjacent tooth holders, which in turn greatly reduces the possibility of sticking of cohesive soil material and makes it considerably easier to wipe off adhering soil material.
  • the width of the tooth head is several times, in particular up to three, four or five times or more, the width of the tooth base.
  • the two head areas can be designed symmetrically or asymmetrically to one another be.
  • At least one cutting body is preferably arranged in the middle between the two head areas.
  • a milling wheel according to the invention With a milling wheel according to the invention, different soil layers and in particular soil layers with cohesive soil material can be milled efficiently, without or at least with a significantly reduced risk of the milling wheel becoming clogged. This improves control of the milling machine and precise positioning of the milling slot.
  • the preferred embodiment of the invention is that all cutting bodies on the tooth head are directed forward in a cutting direction.
  • the cutting bodies can achieve particularly good and uniform removal performance.
  • the cutting bodies can be designed to be identical to one another.
  • the cutting bodies are hard metal bodies which are soldered into the tooth head.
  • the head regions with the cutting bodies are offset from one another in the circumferential direction or are arranged in a cutting line.
  • the line can be straight or curved.
  • the cutting bodies are arranged to one another in such a way that they have the same radial distance from the rotation or center axis of the hub of the cutting wheel and the head areas are symmetrical to a center plane of the cutting tooth. If the two head areas are arranged offset in the circumferential direction, one head area can lead during removal and the other head area can lag behind.
  • the cutting head has a sweep in the cutting direction and that the cutting bodies form a V-shaped arrangement on the cutting head.
  • the subsequent cutting bodies can be arranged evenly offset backwards in the milling direction.
  • the cutting bodies can be designed differently from one another. According to a further development of the invention, it is particularly advantageous that the cutting bodies are designed the same and in particular have a cutting edge.
  • the end faces of the cutting bodies have one or more linear cutting edges, which allow high removal rates on both softer and harder soil layers.
  • the use of the same cutting bodies reduces manufacturing and repair costs.
  • the cutting bodies are made in particular from a high-strength hard metal.
  • any number of circumferential rows can be provided for the tooth holders on the drum-shaped hub, provided that there is a sufficient distance between the circumferential rows.
  • the axial distance between the circumferential rows is preferably between 20 cm and 50 cm.
  • a distance between the individual tooth holders in a circumferential row in a circumferential direction is also between 20 cm and 150 cm.
  • the number of tooth holders in a circumferential row basically depends on the size of the hub on which they are attached.
  • the individual tooth holders are preferably arranged at a predetermined equal angular distance from one another, in particular 60, 90, 120 or 180 degrees.
  • an outer circumferential row is arranged on a free outside of the gear, an inner circumferential row on an inside of the milling wheel directed towards a bearing plate and at least one middle circumferential row are arranged.
  • the individual circumferential rows can be designed differently from one another.
  • one or more foldable teeth so-called folding teeth, can be mounted on the inner peripheral row, which can be pivoted during milling operation into a position below a milling blade on which the milling wheel is mounted.
  • More tooth holders can be arranged than in a middle circumferential row and / or different milling teeth than in the middle circumferential row.
  • the approximately T-shaped milling tooth or teeth are preferably arranged only in the one or more central circumferential rows, which are positioned in the axial direction between the outer circumferential row and the inner circumferential row.
  • L-shaped milling teeth with only one head region extending transversely to the tooth root can be provided on the outer peripheral row and/or the inner peripheral row.
  • the head areas each extend inwards to the at least one middle circumferential row.
  • the number of middle circumferential rows depends on the axial length of the drum-shaped hub and thus depends on the intended milling width.
  • a particularly useful and easy-to-clean design of a milling wheel is that only two central circumferential rows are arranged.
  • Particularly large free spaces can be achieved on the milling wheel according to a further development of the invention in that only two tooth holders with milling teeth are provided in the at least one central circumferential row, which are arranged offset by 180 ° to one another on the circumference of the hub. If there are several middle circumferential rows, the arrangements of the individual circumferential rows can be arranged at an offset angle to one another. With two middle circumferential rows the offset angle can be 90° to each other, with three middle circumferential rows 60° to each other. This counteracts chattering during milling. In particular, this ensures that the plate-shaped milling holders in two adjacent circumferential rows do not lie directly next to one another in the axial direction. As a result, the distances and thus the free spaces between the individual tooth holders are further increased, which counteracts the attachment of soil material and further improves the possibility of stripping off attached material or cleaning it off.
  • a removal rate of a milling wheel can be improved in particular by arranging at least one foldable milling tooth on the inner peripheral side.
  • the folding tooth can be swung out when rotating in an area below the bearing plate, which lies between two milling wheels and keeps them rotating, in order to remove soil material directly below the bearing plate.
  • any number of milling teeth and tooth holders can be provided on the outer peripheral row. It is preferred that the number of milling teeth and tooth holders in the outer peripheral row is greater than the number in a middle peripheral row. It is particularly preferred that twice as many tooth holders are arranged on the outer peripheral row as in a middle peripheral row. In principle, it is also possible to use double tooth holders on the outside. Experience has shown that the use of individual, inclined tooth holders reduces wear on the milling tooth itself and on the tooth holders.
  • Another cutting wheel according to the invention for a trench wall cutter with a drum-shaped hub, on the outer circumference of which plate-shaped tooth holders are arranged in at least one circumferential row, in which cutting teeth for removing soil are detachably held is characterized in that on the outer circumference of the hub two plate-shaped tooth holders are attached to one another in the axial direction are arranged adjacently to form a double tooth holder and that a first milling tooth is accommodated and held in the first tooth holder and a second milling tooth is accommodated in the second tooth holder.
  • Conventional tooth holders can be used, which can absorb higher forces due to their duplication.
  • first milling tooth is designed as a first tooth half and the second milling tooth is designed as a second tooth half, which together form an overall tooth. If only one half of the tooth is damaged [7]only this needs to be changed. This further reduces the maintenance effort.
  • the first tooth half is L-shaped with a tooth base for holding in the first tooth holder and a tooth head with a lateral head area which extends to one side transversely to the tooth base
  • the second tooth half is L-shaped with a tooth base for holding in the second tooth holder and a tooth head with a lateral head area which extends transversely to the tooth base to an opposite side.
  • the two L-shaped tooth halves are designed to be mirror-symmetrical to one another, at least in their head area.
  • a deflector element is positioned in front of the two adjacent tooth holders, through which soil material can be diverted into a side region of the tooth holders. This ensures that the tooth holder is protected.
  • the invention further comprises a milling tooth, which is characterized in that the milling tooth is designed with a tooth head that extends transversely to both sides of the tooth root, that the tooth head has a lateral first head region and a lateral second head region, which extend in opposite directions from one another , and that at least two cutting bodies lying next to one another are arranged on each head area.
  • the cutting tooth according to the invention is used in the cutting wheel according to the invention described above, which results in the advantages described here.
  • a preferred development of the milling tooth is that it has a first tooth half and a second tooth half, which are detachably connected to one another to form the milling tooth.
  • the releasable connection can be done in particular by [8] at least one connecting element, in particular a connecting bolt or a screw.
  • a detachable connection can also include a simple tack weld.
  • the two tooth halves are preferably designed to be mirror-symmetrical to one another.
  • the tooth halves each have a tooth base and a head area.
  • the tooth holding arm can be designed simply, with the strip element being subsequently attached to one side, with the recess being covered laterally.
  • the strip element creates a dead space that is reduced or significantly reduced in one of the two folded end positions of the folding tooth, in particular between the folding tooth and the milling wheel hub.
  • the milling tooth can have a tooth base for insertion into the tongue-shaped recess on the tooth holding arm and a tooth head with at least one cutting body.
  • a conventional milling tooth can be used in the folding tooth arrangement, which reduces the maintenance effort.
  • a particularly simple attachment of the tooth can be achieved in that the milling tooth is fastened in the tooth holding arm in the area of the tooth base via at least one transverse fastening bolt, which extends transversely to a longitudinal direction of the tooth base, and that in the strip element at least one through hole for the fastening bolt is provided.
  • an advantageous folding tooth consists in that the strip element is arranged on the tooth holding arm on the side which faces away from a bearing plate on which the cutting wheel is mounted.
  • the invention further relates to a trench wall cutter with a cutter frame, on the underside of which at least one bearing plate is arranged, with at least one cutting wheel according to the invention being mounted on the end plate, as previously described.
  • stripping elements are attached to the milling frame, which protrude into a space between the circumferential rows with the tooth holders with the milling teeth for wiping off adhering soil material.
  • the stripping elements can in particular be designed like a paddle with a wide stripping blade and a thin holding web arranged thereon.
  • the web is relatively thin and preferably has a width of between 1 cm and 3 cm.
  • a distance between the tooth holders from two adjacent circumferential rows is determined by the size of the cantilevered head area on a T-shaped tooth and the width of the holding bar of a stripping element with a slight distance between the outer edge of the milling teeth and the holding bar of an intermediate stripping element.
  • Such a paddle-shaped arrangement of one or more stripping elements can ensure a safe and reliable stripping of adhering soil material on the drum-shaped hub and the tooth holders with the T-shaped milling teeth. Due to the relatively large free spaces between the individual tooth holders, the stripped floor material can also be reliably removed radially outwards.
  • an advantageous embodiment of a trench wall cutter according to the invention consists in that a total of four cutting wheels are provided, which are mounted in pairs on a bearing plate.
  • the end shield is arranged on an underside of the milling frame.
