    • The invention relates to a rock drill (1) for rotational and percussive action, comprising a drill head (2), a conveying helix (3), a clamping shank and a longitudinal drill axis (L), wherein the drill head (2) has at least one secondary cutting element (5a, 5b) with a front and a rear side face (10a, 10b) and wherein the secondary cutting element (5a, 5b) has a center of mass (M) and a cutting edge (11), the center of mass (M) and the cutting edge (11) defining a first plane (E1), the front side face (10a) of the secondary cutting element (5a, 5b) defining a second plane (E2) and the rear side face (10b) of the secondary cutting element (5a, 5b) defining a third plane (E3). In this arrangement, the longitudinal drill axis (L) intersects the first plane (E1) at a first point of intersection (S1), the longitudinal drill axis (L) intersects the second plane (E2) and/or the third plane (E3) at a second and/or third point of intersection (S2, S3), the longitudinal drill axis (L) and the first plane (E1) form a first acute angle (1) in the direction of advancement (x) of the rock drill (1) and the longitudinal drill axis (L) and the second and/or third plane (E2, E3) form a second and/or third acute angle (2, 3) in the direction of advancement (x) of the rock drill (1).
    • 本发明涉及一种用于旋转和冲击作用的凿岩机(1),包括钻头(2),输送螺旋(3),夹紧柄和纵向钻杆轴(L),其中钻头(2) 具有至少一个具有前侧面和后侧面(10a,10b)的次切割元件(5a,5b),并且其中所述次切割元件(5a,5b)具有质心(M)和切割刃(11) ),质心(M)和限定第一平面(E1)的切割刃(11),二次切割元件(5a,5b)的前侧面(10a)限定第二平面(E2),并且 第二切割元件(5a,5b)的后侧面(10b)限定第三平面(E3)。 在这种布置中,纵向钻孔轴线(L)在第一交点(S1)处与第一平面(E1)相交,纵向钻孔轴线(L)与第二平面(E2)和/或第三平面(E3 )在第二和/或第三交叉点(S2,S3)处,纵向钻杆轴线(L)和第一平面(E1)在岩石的前进方向(x)上形成第一锐角(1) 钻头(1)和纵向钻杆轴线(L)以及第二和/或第三平面(E2,E3)在岩石的前进方向(x)上形成第二和/或第三锐角(2,3) 钻(1)。
