Abstract
Machine for cleaning gratings for hydraulic weirs, comprising an oscillating arm (3) which oscillates at a pivoting point (2), and a double-acting cylinder (9) intended to position the oscillating arm (3). The above mentionned arm bears, in its interior, a carriage (5) carring the blade (11), which slides by means of wheels (6) rolling on two rails (4), this arrangement making possible the access to any point of the grating for cleaning purposes, owing to the above-mentioned sliding of the carriage (5) inside the arm (3) and also to the displacement of the machine along the weir by means of the rails or guides on which may slide the rollers integral with the base of the machine.

Claims (5)
1.- Machine for cleaning gratings by means of an oscillating arm for hydraulic weirs, of the type used to take out dirt which is accumulated on the gratings of weirs, characterized in that it is composed of an oscillatory arm which by means of a pivoting point and using a double-acting cylinder, said arm may adopt positions which enable the arm to reach to any point of the grating even though said grating has irregular form, the displacement of said machine along the weir being possible by means of wheels which are displaced over guides or railes fixed on the ground.
2. Machine for cleaning gratings, according to claim 1, characterized in that the oscillatory arm is defined by a profile in form of "?" or the like, and guides that are installed along in the interior of said profile, which guide permit the displacement of the carriage which supports a spoon or shovel.
3. Machine for cleaning gratings, according to previous claims, characterized in that the dragging of the carriage which supports the spoon is carried out by means of a chain which runs inside the oscillatory arm, and the movements of said chain being controlled by means of a hydraulic motor situated at the exterior end of the oscillatory arm.
4.- Machine for cleaning gratings, according to previous claims, characterized in that in order to place the collected dirt on the transport this is done by tilting said spoon without a pass-way or a window.
5.- Machine for cleaning gratings, according to previous claims, characterized in that it may be activated either by electric or hydraulic mechanisms, said mechanisms can be controlled in manual or automatic forms indistinctly.
