ACCESSORY FOR EXCAVATION OF A DITCH AND RELATED METHODS

摘要

Implementations of the accessory and associated methods allow for excavation of a ditch, wherein rotating grating means are used for expelling rubble and form a ditch. The accessory includes grating means which are moved with respect to the ditch to ensure contacting of the grating means with the road and alignment of a rotation axis of the grating means with the ditch axis. The ditch is progressively excavated when the grating means are rotated and displaced along the ditch axis. The grating means may be connectable to a mobile device through an arm assembly configured to controllably move the grating means from the mobile device. The accessory may be used for connection to a mining device for excavating the ditch along the road of an underground mining tunnel.

主权项

1. An accessory for excavation of a ditch along a road, the accessory being mountable on a mobile device and comprising:
a grating assembly comprising:
a rotor having a rotation axis; anda plurality of grating members projecting outwardly from an external surface of the rotor and configured for expelling rubble from the ditch; and an arm assembly connected to the grating assembly, the arm assembly comprising:
a base movably connectable to the mobile device, movement of the base with respect to the mobile device allowing the connected grating assembly to contact the road;an elongated arm having a proximal end and a distal end;an arm pivot assembly, the proximal end of the arm being connected to the base by the arm pivot assembly for enabling pivoting of the arm with respect to the base, so as to align the rotation axis of the rotor of the grating assembly with a ditch axis; androtating means cooperating with the distal end of the arm and further engaging the rotor of the grating assembly to enable rotation thereof with respect to the arm assembly, so as to excavate the ditch upon displacement of the mobile device along the ditch axis.
