<p>The device has a unit for applying a control signal representative of working speed of tool and drilling rate of a soil treatment machine. A comparing unit compares effective working speed with resulting working speed of the tool from a selection of indicative values of different soils to be treated for determining, when the difference between the two speeds exceeds a principle threshold, another working speed and another drilling rate. The device has a unit for storing indicative values of different soils to be treated and indicative values of predefined working speed of the tool and predefined drilling rate of the machine. An independent claim is also included for a method for controlling a drilling rate of a soil treatment machine and a working speed of tool of the machine.</p> |
