    摘要： Soil working tool for an agricultural machine, in particular a cultivator, which is fixed on a tool holder and has a tine-like region to which a preferably guide plate-like element is attached. In order to achieve an improved soil flow across the soil working tool with good wear protection and thus a sufficient service life of the soil working tool, the tine-like region has two side strips which run in the longitudinal direction of the soil working tool and have notch-like recesses extending in the transverse direction, and that an at least approximately smooth center strip region is located between the two side strips in the center in the longitudinal direction of the tine-like region of the soil working tool.

    摘要： The invention relates to a milling pick, in particular a round pick having a pick head (40), which has a pick tip (30) made of a hard material as a cutting element, wherein furthermore a pick shank (10) is provided, which is coupled directly or indirectly to the pick head (40), wherein a wear-protection disk (20) is provided, the cut-out of which, in particular a drilled hole, is pushed onto the pick shank (10),
    wherein the wear-protection disk (20) has, on its side facing the pick head (40), a counterface (23), which is designed to come into contact with a bearing surface (41) of the pick head (40), wherein the wear protection disk has, facing away from the counterface (23), an underside support surface (21), which is preferably parallel to the counterface (23), and wherein a disk thickness (d) is formed between the counterface (23) and the support surface (21), is characterized in that the ratio of the diameter of the pick shank (10) located in the area of the cut-out (25) to the thickness of the disk (d) being in the range from 1.5 to 3.75, preferably in the range from 2 to 3.

    摘要： The invention relates to a milling pick, in particular a round pick having a pick head and a pick tip, consisting of a hard material, wherein the pick tip has an attachment area, which is used to connect it to the pick head, wherein the pick tip has a concave area, which extends in the direction of the central longitudinal axis of the pick tip, and wherein the concave area has an elliptical contour. To achieve an improved resilience for such a milling pick, provision in made in accordance with the invention that the ellipse generating the elliptical contour is arranged in such a way that the semimajor of the ellipse and the central longitudinal axis of the pick tip form an acute angle.

    摘要： The invention relates to a scraper bar (20) for a scraper blade (68) of a road milling machine, having a carrier (10) that comprises a front side and a rearward installation surface (17), the carrier (10) comprising a cutting-element receptacle (13), cutting elements (30) being held, serially arranged along a longitudinal axis (L) extending in a width direction of the carrier (10), on or in the cutting-element receptacle (13), and the cutting elements (30) comprising a cutting edge (35.1) that transitions indirectly or directly into a rake surface (35). In order to improve the working result, provision is made according to the present invention that at least for some of the cutting elements (30), the cutting edge (35.1) is set at least locally not parallel to the longitudinal axis (L).
