Abstract
La présente invention concerne un nouveau dispositif brise-roches. Le dispositif comprend une chambre cylindrique creuse munie d'une extrémité inférieure fermée, une extrémité supérieure fermée, un trou d'accès dans l'extrémité supérieure fermée et une surface circulaire extérieure. Un poussoir est placé dans l'axe longitudinal et de manière réciproque à l'intérieur de la chambre cylindrique, le poussoir étant orienté vers une position rétractée. L'extrémité supérieure du poussoir comporte une surface supérieure et une partie convexe sous la surface supérieure. Au moins deux tiroirs, de préférence quatre, sont placés à distance égale autour de la circonférence du poussoir cylindrique, chaque tiroir comprenant une extrémité supérieure convexe configurée de façon à glisser avec la partie convexe du poussoir cylindrique. De même, au moins deux, de préférence quatre, pièces rapportées durcies sont fixées sur une surface extérieure d'un poussoir apparié. Chaque pièce rapportée durcie comporte une surface extérieure partiellement circulaire, qui est coextensive avec la surface circulaire de la chambre cylindrique. Chaque poussoir et chaque pièce rapportée durcie sont orientés vers une position intérieure rétractée.
