Definitions
- the invention relates to a stone breaking apparatus for mounting on the arm of a wheeled loader or similar vehicle.
- the apparatus is meant to serve as auxiliary equipment for splitting of large blocks of stone, where the apparatus comprises a fastening means with rapid release coupling for mounting on the arm, and an obloncr cylinder to guide therein a sliding, hoistable weight or piston for fall engagement with a hardened impact tool disposed in the lower end section of the cylinder.
- this is achieved by the cylinder's having limited movability in relation to a fastening means along one or more guide elements substantially parallel with the longitudinal axis of the cylinder.
- a fastening means along one or more guide elements substantially parallel with the longitudinal axis of the cylinder.
- shock absorbers between the cylinder and the fastening means there may be mounted one or more shock absorbers, the longitudinal axis thereof running substantially parallel with the longitudinal axis of the cylinder.
- the stone breaking apparatus is further provided with a rapid release coupling for simple mounting and dismounting to/from the arm of a wheeled loader or similar vehicle.
- Fig. 1 shows the stone breaking apparatus 1 which is adapted for mounting on the arm (not shown) of a wheeled loader or similar vehicle.
- the apparatus 1 is mounted on the vehicle's arm over the fastening means 4 by rapid release couplings 5.
- the apparatus 1 comprises a cylinder 2 for guidance of the weighted element 6.
- a hydraulic motor 16 drives a cable pull device 18 by means of a chain transmission 17.
- the cable pull device 18 is connected to the weighted element 6 by a wire cable 15 for hoisting the weight to an upper position in the cylinder 2.
- a disconnecting means (not shown) on the cable pull device 18 makes possible disconnection of the weighted element from the hoisting mechanism 18 for an approximate free fall within the cylinder 2.
- a hardened impact tool 7 is detachably infixed thereto.
- the impact tool has limited movability in the guide sleeve 12.
- the guide sleeve 12 is shown infixed to the cylinder 2 by means of bolt connections.
- Between the lower flange on the cylinder 2 and the flange on the guide sleeve 12 are disposed one or more hard rubber liners 21.
- the impact tool's 7 movement is restricted by means of a blocking bolt 14, which bolt is fastened to the guide sleeve 12.
- the blocking bolt 15 engages with a worked groove in the upper part of the impact tool 7.
- Around the lower part of the cylinder 2 there is attached a reinforcing flange 19 extending along the circumference thereof.
- brackets 10, 11 for fastening one or more guide bars 3.
- a stopper 20 On the lower part of the guide bar 3 is provided a stopper 20.
- holders for example, in the form of H-beams, to anchor the upper section of one or more shock absorbers 8.
- holders On the fastening means 4 there are similarly provided holders, e.g., in the form of an H-beam, to anchor the lower section of one or more shock absorbers 8.
- the fastening means 4 is provided with guide elements 13 for sliding engagement with the guide bars 3.
- the stone breaking apparatus is brought to a suitable place on the stone block which is to be split.
- the apparatus is maneuvered and positioned by means of the various functions which can be executed by the arm of a wheeled loader or similar vehicle.
- the cylinder 2 is positioned substantially vertically on the stone block. With the impact tool 7 resting against the stone block, the fastening means 4 is brought down toward,but not necessarily into, the stopper 20.
- the motor 16 is supplied with hydraulic fluid via hoses from the vehicle's hydraulic system.
- the hydraulic motor 16 drives the cable pull device 18 and thereby hoists the weighted element to the desired height.
- the height of the weighted element 6 in the cylinder is determined on the basis of the stone block to be split, based on both the size, form, and material character of the block.
- a disconnecting means or clutch in the cable pull device 18 makes possible a free-fall movement of the weighted element 6 in the cylinder 2.
- the weighted element 6 impinges on the hardened impact tool 7, and the shock-like impact thereof against the stone block splits the block. Any "residual forces" remaining after the stone is split are absorbed by the shock absorber 8. If the tool is inaccurately placed, or the stone block is able to be split considerably more easily than expected, the substantial portion of the impact is received by the shock absorber 8, so that the wheeled loader arm and its components are spared the direct stresses of the shock impact.
- the displacement of the cylinder 2 in relation to the fastening means 4 may be as much as 70-80 cm.
- the impact tool 7 and the cylinder 2 usually will be retarded rapidly down through the split stone, so that the stone breaking apparatus 1 might also be used without the shock absorber 8.
- the guide bar 3 must also be equipped with an upper stopper against which the cylinder 3 rests during movement of the apparatus 1 from one place to another.
- the stone breaking apparatus is used with the shock absorber, this takes up the weight of the cylinder 3 during transfer movement and thereby functions as an upper stopper.
