Description

Chisel device of excavator
Technical Field
The present invention relates to a chisel device arranged in connection with a pivoting tool mount on a work machine, wherein the pivot of the tool mount forms the operating pivot of the chisel device, and wherein the chisel device comprises a housing with a coupling part arranged to be attachable to the tool mount and a reciprocally movable chisel protruding from an end of the housing, and a reciprocally movable chisel.
Background
Hydraulic chisels are used to break apart rock, concrete and other solid materials, the chisel being connected, for example, to the arm of an excavator and being driven by a hydraulic system integrated in the machine to which the chisel is connected. Chisels are elongated and relatively thin and are not well suited to moving the material being split.
US 4602821a discloses a hydraulic chisel provided with a clearing blade or clearing blade which can be pivoted or displaced between an inactive locked position along the housing and an active locked position in which the front edge projects beyond the end of the chisel, the clearing blade or clearing blade being adapted to remove broken material.
KR 20160067339a discloses a clearing blade which is displaceable hydraulically along the chisel housing in a guide arranged on the chisel housing between an inactive retracted position and an active extended position in which the front edge projects beyond the end of the chisel in order to remove separated material.
From JP H01252375A a clearing blade arranged on a chisel housing is known, which is hydraulically pivotable between an inactive position along the chisel housing and an active position in which the clearing blade extends along the chisel and beyond the chisel end.
AU 559417B2 discloses a clearing blade that pivots between an inactive locked position along the chisel housing and its working position extending along the chisel. The chisel may be released from its locking inactive position by remote control of the locking device.
A disadvantage of a clearing blade that is displaceable or rotatable relative to the chisel housing is that the assembly of the chisel housing and the clearing blade must contain complex and fragile functions in order to be able to change over the clearing blade.
Disclosure of Invention
It is an object of the present invention to remedy or reduce at least one of the disadvantages of the prior art or at least to provide a useful alternative to the prior art.
The object is achieved by the features specified in the description below and in the appended claims.
The present invention provides a chisel device arranged to be mounted (fit) to a tool mount on a work machine, in particular an excavator, the chisel device being provided with a tool manipulator in which a clearing blade is rigidly attached to a housing, the clearing blade protruding from the circumference of the housing and being provided with a front edge substantially parallel to the pivot axis of the tool mount, which is also the operating pivot axis of the chisel device. When the chisel device is in the normal position, that is to say the chisel is directed towards the surface to be broken, the clearing blade has a good clearance from the surface and does not prevent the chisel from working on the surface. When loose material is to be removed from the working area of the chisel, the chisel device would be tilted about the pivot of the tool mount so that the leading edge of the clearing blade faces the surface, and the loose material would be pushed away to expose the surface and prepare it for further excavation.
Preferably, the clearing blade is arranged in the immediate vicinity of a (intermediate visibility) coupling portion arranged to connect the chisel device and the tool mount. The cleaning blade may be integrated in the coupling part.
Preferably, the working width of the clearing blade is greater in width than the extent (extension) of the tool mount.
Preferably, the cleaning blade is formed by a plate element provided with a reinforcing rib extending from a front edge of the cleaning blade.
It is advantageous if the cleaning blade has side walls extending from the front edge and forming at least some of the reinforcing ribs of the cleaning blade.

Detailed Description
Reference is first made to fig. 1. The chisel device 1 known per se comprises a housing 11 comprising in a first end 111 a coupling part 14 arranged for releasable connection to a tool mount 31 on the work machine 3, here shown as an arm on an excavator. A reciprocable chisel 12 projects from the second end 112 of the housing 11. In a manner known per se, the housing 11 houses a drive device (not shown) of the chisel 12, typically a hydraulic drive device driven by a hydraulic system (not shown) of the work machine 3. The longitudinal axis 13 of the chisel is perpendicular to the operating pivot 15 of the chisel device 1. The operating pivot 15 is formed by a rotation axis 32 of the tool mount 31 with respect to the work machine 3.
The cleaning blade 2 is attached to the chisel device 1 at a first end 111 of the housing, here shown attached to the coupling portion 14 by means of a blade attachment 23. In an embodiment not shown, the cleaning blade 2 may be integrated into the coupling part 14.
The clearing blade 2 projects rigidly from the periphery of the housing 11, here shown perpendicular to the longitudinal axis 13 of the chisel 12. The angle of the cleaning blade 2 with respect to said longitudinal axis 13 may be adjustable.
The cleaning blade 2 is formed by a blade plate 21 having a front edge 211. The blade plate 21 is preferably supported by means of a reinforcing rib 22, here shown as two opposing side walls extending rearwardly from the front edge 211 for the entire extent of the blade plate 21. In the embodiment shown, the blade plate 21 extends along both sides of the entire coupling portion 14.
