Abstract

Antipolvo disposition for machines of drilling of terrains, of the type of machine that includes a frame in which it is joined a column in which is mounted the hammer of perforation, which consists of a pneumatic set feed by a compressor, through a first drive, with air of device that determines, through a percutor perfuted centrally and of the timely mechanisms, the drilling movements of a pin of output, also perforated centrally, being the bottom of the shank coupled to a tubular varillaje which, in its lower extreme, takes the tubular bit, to which these drilling movements are transmitted, the hammer and percutor are traveled centrally by a scanning air needle, consisting of a tubular duct whose end of entrance is underwater. Exterior of the body of the hammer, above the top of this, being connected said extreme of input of the needle with unansegun da air conduction driver, for sweeping, being the extreme of output of the needle connected with central drilling of the shell, so that the scanning air injection can be performed from above the top of the hammer, and by the hollow center of the needle, the shank, the varillaje and the bit, to the background of the drill to sweep, by the exterior of the bit and to the surface, the dust and the drill detritus, the disposition is characterized because it includes a source of water at pressure, means that connect the source of water with the central orifice of the varillaje to send gua inside of this and to the fund of the drilling, and means to control the water flow that is sent from the source towards the background of the drilling.
