Definitions
- the present invention relates to an arrangement according to the pre-characterising clause of the patent claim.
- US 6238277 Bl discloses a mobile machine of the said type.
- the object of the present invention is to release the operator of the grinding machine from the actual propulsion of the machine. This is achieved in that the invention has the features specified in the characterising part of the patent claim.
- the invention furthermore affords the advantage that a dust/sludge suction unit, which is coupled to the grinding machine via a suction hose, can be located in close proximity to the grinding machine in the space normally occupied by the operator.
- the suction hose can thereby be made shorter so that the flow losses therein are reduced and the suction capacity is increased. If this increased suction capacity cannot be utilised in order to improve the result, there is the alternative option of reducing the energy required for the suction, thereby achieving an energy saving.
- Fig. 1 shows, in schematic form, a perspective front view of a grinding machine according to the invention having a dust suction unit coupled thereto by a short suction hose;
- Fig. 2 shows, by way of example, a plan view of the grinding machine according to
- Fig. 1 from the rear and how an operator controls the grinding machine remotely;
- Fig. 3 shows grinding disks arranged on a planet disk.
- FIG. 1 generally denotes a mobile machine for grinding floor surfaces according to the present invention.
- Fig. 1 shows how a dust suction unit 3 is connected to the grinding machine 1 by a very short suction hose 2.
- the short suction hose 2 affords great advantages and is possible due to the fact that the dust suction unit 3 can be located in the space normally occupied by an operator.
- the grinding machine comprises a housing la with a drive motor lb arranged thereon and is supported partly by two wheels 4, 5 and partly by grinding disks lcl, lc2, lc3, lc4 located at the bottom of the housing and rotatably supported on a planet disk Id.
- a drive motor lb arranged thereon and is supported partly by two wheels 4, 5 and partly by grinding disks lcl, lc2, lc3, lc4 located at the bottom of the housing and rotatably supported on a planet disk Id.
- a drive motor 4a, 5a is mechanically connected to each wheel 4, 5 and is in turn electrically connected by leads 4b, 5b to a control unit 6.
- the latter comprises means, familiar to the person skilled in the art, for controlling the motors 4a, 4b and hence the direction of rotation and the rotational speed of the wheels 4, 5 as a function of control signals from an operating device 7, which is manually actuated by an operator 8.
- the control signals are transmitted from the operating device 7 to the control unit 6 via radio communications units in the operating device 7 and the control unit 6, as illustrated by antennae 6a and 7a connected to these respectively.
- the arrangement according to the invention allows the operator 8, from a location affording a good, clear view of the floor surface that is to be ground, to carry out this grinding and, if so required, to briefly study the grinding result at close quarters, and if required to control the machine in order to locally repeat the grinding.
- the said electrical cables are suitably brought together on a carriage (not shown) or suspended above the floor surface that is to be ground.
