Abstract

The invention relates to a pick (10), in particular a round shaft pick having a pick head (13) and a pick shaft (11), a securing sleeve (20) being mounted in the region of the pick shaft, and a support element (30) comprising a guide region (36) being associated with the pick. According to the invention, in order to be able to dismantle the pick (10) easily from the pick holder (46) and optionally to be able to refit it easily again, the support element (30) comprises a deflection section (36.1) in the region of its underside remote from the pick head (13).

Abstract

The invention relates to a soil treating tool for an agricultural machine, particularly a plow point, plowshare, or harrow point having a carrier (10) comprising a cutting region (14) having a cutting edge, wherein one or more carbide elements are disposed in the cutting region. For such soil treating tools, an improvement in service life properties can be achieved in that the carbide element is a cutting element (20) forming at least a part of the cutting edge.

Abstract

A shank chisel including a chisel head and a chisel shank, wherein the chisel shank bears a clamping sleeve in which the chisel shank is held captively in a direction of a longitudinal axis and is freely rotatably about the longitudinal axis. To allow the shank chisel to be both assembled and disassembled through a chisel receptacle of a chisel holder that is formed as a receiving bore, according to this invention, the chisel shank bears at its end remote from the chisel head a shank extension, the shank extension has a tool receptacle, and the tool receptacle is accessible by way of a spacing region of the shank extension in the axial direction of the chisel that is set back from the lateral surface of the chisel shank and/or from the lateral surface of the clamping sleeve.

Abstract

A circular-shank tool including a tool holder for improving the centering of the shank of the circular-shank tool in the locking sleeve by a configuration of the retaining elements and to improve an ability of the shank to rotate in the sleeve. To achieve this, the retaining elements are distributed between two stamped edges that lie transversely with respect to a longitudinal axis of the locking sleeve and are stamped inwards or indented, the stamped edges extend over part of the circumference of the locking sleeve and are interspaced at a distance that corresponds to the width of the peripheral groove in the shank of the circular-shank tool and the retaining elements form a coaxial concave centering section facing the convex groove base of the peripheral groove.

Abstract

The invention relates to a shank chisel, particularly a chisel for milling roads, with a carrier part (10) comprising a shank (11), wherein the shank is provided with a chisel tip (18) made of a hard material. The carrier part comprises a receiving section (14) in the region between the shank and the chisel tip, a head part (30) being held on said receiving section, and the head part comprises a peripheral chip discharge surface (34.1) that is tapered in the direction of the chisel tip. In order to provide an optimized shank chisel of said kind in terms of wear, the invention provides for the head part to be rotatably held with respect to the carrier part.

Abstract

The invention relates to a shank chisel comprising a chisel head (10) and a chisel shank (20), wherein the chisel shank bears a clamping sleeve (23), in which the chisel shank is held captively in the direction of its longitudinal axis and freely rotatably about its longitudinal axis. To allow such a shank chisel to be both assembled and disassembled through a chisel receptacle (31) of a chisel holder (30) that is formed as a receiving bore, it is provided according to the invention that the chisel shank bears at its end remote from the chisel head a shank extension (20.1), that the shank extension has a tool receptacle (26), and that the tool receptacle is accessible by way of a spacing region of the shank extension in the axial direction of the chisel that is set back from the lateral surface of the chisel shank and/or from the lateral surface of the clamping sleeve.

Abstract

The invention relates to a crushing tool comprising a tool holder that carries at its base a first and second holder, the two holders being arranged at a distance to each other in the tool feed direction and each of the holders comprising at least one cutting element. In order to improve the wear characteristics of such a crushing tool, the invention is characterized in that at least one of the holders has a receiving element with a tool holder removably inserted therein, such that the tool holder receives a removable tool insert and the tool insert carries the cutting element.
