- an oxidation protection layer is provided between the hard material and the intermediate material and / or between the intermediate material and the tool body, this can advantageously promote a high resistance of the tool.
- an advantageous embodiment variant of the invention consists in that the tool is designed as a chisel with a bit body and the functional unit as a chisel tip which is positively and / or materially connected to the bit body.
- the chisel tip can be soldered at least partially to the bit body, wherein the Lötnaht form the intermediate material and / or another intermediate material may be provided.
- the bit tip may comprise another material, for example PCD, which can further increase the stability of the tool.

- the damping element By the damping element, the impact energy is absorbed in the impact of, for example, stone-like materials on the hard material partially. In this way can advantageously be reduced wear resistance and a longer service life, in particular the risk of breakage of the wear protection layer. Furthermore, a reduction of the impact noise can be achieved.
- the screening device preferably has transverse struts running transversely to a material conveying direction to be conveyed, and longitudinal struts extending longitudinally to a material conveying direction to be conveyed, wherein the transverse and longitudinal struts form sieve openings.
- the screen openings can be rectangular, in particular square, for example. By forming the screen openings based on the struts, the area size of the screen openings can be easily designed for specific processing tasks in which the distance between the struts is varied.
- the transverse and / or longitudinal struts have side surfaces which are inclined at least in regions by an angle ⁇ with respect to the vertical center longitudinal plane of the transverse and / or longitudinal struts.
- the inclination is in such a way that the distance of the side surfaces down, in the direction away from the wear protection layer, decreases in size. Since the side surfaces at least partially surround the sieve openings, this orientation results in a downwardly increasing clear cross section of the sieve openings. As a result, the screenings can fall through the screening device more easily, with a reduced risk of jamming.
- the angle ⁇ could for example be between 2 ° and 30 °, in particular between 5 ° and 10 °, and be the same or different for different side surfaces. Also, other returning surface courses are conceivable, for example arched type.
- a main body of the base unit cross-strut body and / or longitudinal strut body has, which are assigned to the transverse and / or longitudinal struts, and if the Damping element has the transverse and / or longitudinal struts associated Quererstben- and / or L jossstreben harshen, which are applied at least partially on the facing in the direction of wear protection top surfaces of the transverse strut and / or longitudinal strut body.

- impact noise attenuated by für fallendem screenings which gets into contact with the side surfaces of the strut body.
- Efficient wear protection can be obtained by forming the wear protection layer on the upper side of the screening device on the transverse struts by transverse elements and on the longitudinal struts by longitudinal elements.
- the upper side of the screening device points in the direction of conveyed, unclassified material. Due to the formation of the wear protection layer by individual elements, a segmentation of the wear protection layer is achieved, which advantageously prevents breakage of the wear protection layer and its stability can be increased.
- the transverse and / or longitudinal elements can be designed to be elongated in their surface extent on the top, but also for example square or with a length shorter than the width.
- the transverse elements at the sides of the cross struts pointing in the opposite direction to the material to be conveyed lead to the formation of a protective surface which, at least in some areas, forms the side surfaces facing the material conveying direction.
- a protective surface which, at least in some areas, forms the side surfaces facing the material conveying direction.
- an advantageous pressure distribution of the longitudinal elements on the longitudinal strut layer can be obtained by virtue of the fact that the longitudinal elements have a substantially trapezoidal cross-section perpendicular to their vertical central longitudinal plane.
- substantially means that two parallel surfaces, in this case the upper side and the lower side, In addition, rounded surfaces are provided between the surfaces in the present case, and the connecting part is integrally formed on the lower element on the lower side be achieved.
- At least two transverse and / or longitudinal elements are arranged on a portion of the transverse and / or longitudinal struts, which is associated with one of the screen openings.
- the longitudinal elements of the longitudinal struts are arranged directly behind one another over at least part of the intersection regions of the longitudinal and transverse struts. In this way, at least part of the crossing regions between transverse and longitudinal struts is covered by means of the longitudinal elements. This advantageously results in a continuous surface along the conveying direction of the bulk material. In this way, disturbing transverse shoulders and / or transitional areas in the longitudinal guides can be minimized, which contributes to better bulk material guidance.
- the screening device has side parts with openings for receiving fastening means. It can be advantageous for the breakthroughs Covers, in particular of damping material, be provided. In this way, a largely continuous surface of the side parts can be achieved, whereby, for example, less bulk material can be deposited.

- a projection 11.2 made of hard material material integrally formed or positively and / or cohesively attached, for example, soldered.
- an oxidation protection layer 11.3 may be provided to protect the hard material from corrosion.
- a damping body 11.4 on the approach 11.2 and the oxidation protection layer 11.3 force, form and / or materially attached.
- the damping body 11.4 is substantially more elastic than the remaining part of the bit tip 11 (eg, modulus of elasticity between 80 and 150 GPa) and, for example, made of copper, silver, nickel or a corresponding alloy.
- the chisel tip 11 is inserted with the projection 11.2 and the damping body 11.4 on a bit body 12 in a designated, upwardly facing receptacle and force, positively and / or cohesively on the bit body 12 fixed, for example, with the approach 11.2 soldered to the bit body 12.

- the groove 12.1 serves as a tool holder, in which a disassembly tool can be used. By means of this disassembly tool, the bit 10 can be dug out of the bit holder. Other embodiments of the bit 10 are conceivable.
- the damping body 11.4 causes shocks are damped when hitting the chisel tip 11 to be processed hard material due to the increased elasticity. This results in a lower abrupt impact load on both the bit tip 11 and the bit body 12 and the machine. This may be particularly advantageous when used with PCD, as this material has a lower impact resistance than, for example, carbide. Overall, such an increased stability of the bit 10 can be achieved.
- FIG. 2 shows, as a further example of the tool according to the invention, a screening device 20 in a perspective view from above.
- the screening device 20 can be used, for example, in machines for classifying or presorting bulk material, for example of stone and / or crushing material, but also, for example, in the agricultural sector.

- the screening device 20 has on its side pointing in the direction of the conveying direction F and on the opposite side, side parts 24, which are provided with openings 60 for fastening the screening device 20 to the machine.
- the screening device 20 has a base unit 50 arranged on its underside, which is essentially made of a metallic material, for example of steel.
- a damping element 40 for example in the form of a damping plate, is positively and / or firmly attached to the base unit 50 as intermediate material.
- the damping element 40 is made of a material that has a higher elasticity than the base unit 50. It may in particular be made of plastic and / or a composite material and be applied to the base unit 50, for example, by a casting method, or another method. In addition, an oxidation protection layer (not shown here) could be provided between the base unit 50 and the damping element 40. On the underside of the top of the screening device 20, on which the bulk material is conveyed, a wear protection layer 30 is mounted on the damping element 40 as a further part of the functional unit. An oxidation protection layer could also be arranged between the wear protection layer 30 and the damping element 40.

Also, that edge of the side part 24, which forms a boundary of screen openings 23 against the conveying direction F, ie in the last row, is provided with transverse elements 31 (see FIG. 4). The edge of the side part 24 which forms a boundary of screen openings 23 in the conveying direction F, ie in the first row, is equipped with longitudinal elements 32, although the edge runs transversely. This is due to the fact that the transverse elements 31 are designed to encompass an edge lying opposite to the conveying direction F, which edge is not present at this transverse edge.
- the transverse and longitudinal elements 31, 32 are wear-optimized formed by being made of a hard material. On those sections of the transverse and longitudinal struts 21, 22, and also on portions of the delimiting edges of the side parts 24, which each define one of the screen openings 23, at least two transverse or longitudinal elements 31, 32 are respectively arranged. This relatively notedgliedrige training of the transverse or longitudinal elements 31, 32 advantageously reduces the likelihood of breakage of the transverse or longitudinal elements 31, 32 at sudden loads and thus increases the resistance of the wear protection layer 30 and the wear protection element.

- guides 51.2 of the angle elements 51 are attached, for example welded, to the supports 51.1, extending essentially along the delimiting edges of the side parts 24.
- the angle elements 51 serve for the exact arrangement of the screening device 20 in the machine.
- a base body 53 of the base unit 50 with side elements 51.1 is arranged as parts of the side parts 24. Furthermore, the main body 53 cross member body 53.2 and longitudinal strut body 53.3 as components of the transverse or longitudinal struts 21, 22.

The webs are arranged below each second longitudinal strut 22, beginning in each case on the inside of the respective outermost row of screen openings 23. The webs serve to stabilize the base unit 50 or the screening device 20.

- the square, in particular rectangular, screen openings 23 can be seen, each of sections of two longitudinal struts 22 and two transverse struts 21 or of edges of the side parts 24 are included. They are aligned with their longitudinal direction in the conveying direction F.
- Other shapes and orientations of the screen openings 23 are possible depending on the classification task, for example, square openings or with in Longitudinally transverse to the conveying direction F aligned rectangles.
- FIG. 4 shows the wear protection layer 30 with the arrangement of the transverse and longitudinal elements 31, 32.
- the elements 31, 32 are of such longitudinal extent that at least two elements 31, 32 are arranged per screen opening 23 delimiting section of the transverse and longitudinal struts 21, 22. As a result, a segmentation of the wear protection layer 30 is obtained, by which the risk of breakage of the wear protection layer 30 is minimized. The segmentation could also be realized by larger and / or in particular by smaller elements 31, 32. Furthermore, it can be seen that the longitudinal elements 32 are arranged directly behind one another along the longitudinal struts 22, so that a largely continuous course of the wear protection layer 30 formed by the longitudinal elements 32 results on the longitudinal struts 22. In particular, the crossing regions between transverse and longitudinal struts 21 and 22 are covered by longitudinal elements 32.

- the protective surface 31.4 forms a part of the side surface 21.1 counter to the conveying direction F, and is correspondingly inclined by the angle ⁇ .
- the angle between the transverse surface 31.1 and the protective surface 31.4 is 90 ° - a.
- the protective surface 31.4 is protected against bulk material pointing in the opposite direction to the conveying direction, since this preferably also strikes this side or edge on account of the conveying direction.
