    • For cutting rock by means of cutting head (1) having its bits (24) cooperating over a limited axial shifting stroke (a) with a cylinder-piston-aggregate, for example a valve (18), it is proposed to intermittently subject the cylinder-piston-aggregate to the action of pressurized fluid, thus exposing the bit (24) during its engaging the rock to percussion forces. During the phases lacking any action of pressurized fluid onto the cylinder-piston-aggregate, the bit (24) shall be pushed into its starting position. This embodiment can be realized with both hydraulic and pneumatic cylinder-piston-aggregates, noting that in case of an embodiment having a hydraulic cylinder-piston-aggregate it is preferred to design this cylinder-piston-aggregate as a valve (18) which simultaneously provides the possibility to expel pressurized liquid via a spraying nozzle (32) onto the mine face. (FIG. 2)
    • 为了通过具有其位(24)的切削头(1)切割岩石,所述钻头(24)在有限的轴向移动行程(a)上与气缸 - 活塞 - 集料(例如阀)(18)配合,建议间歇地对待 气缸 - 活塞 - 聚集到加压流体的作用下,从而使钻头(24)在其接合岩石期间暴露于敲击力。 在没有加压流体到缸 - 活塞 - 集料的任何作用的阶段期间,钻头(24)应被推入其起始位置。 该实施例可以通过液压和气动缸 - 活塞 - 集料来实现,注意到在具有液压缸 - 活塞 - 集料的实施例的情况下,优选地将该缸 - 活塞 - 集料设计为同时的阀(18) 提供通过喷嘴(32)将加压液体排出到矿井面上的可能性。 (图。

    • A bit holder equipped with a spraying device, comprising a receiving bore (2) in which the bit shaft (3) is supported, for limited axial shifting movement and optionally for being rotated, shifting movement of the bit shaft (3) in direction of the cutting pressure being limited by abutment (5) and the bit shaft being loaded by a return force in opposite direction to the cutting pressure and a valve (10, 11) for the supply of water to the bit or to the working or drift face during cutting operation being arranged within the bit holder (1) and being opened under the action of the cutting pressure by the axial shifting movement of the bit shaft (3). The valve housing (9) is inserted into the receiving bore (2). The rear end of the bit shaft (3) acts directly on the shaft (12) of the valve cone (10). Within the mantle of the receiving bore (2) and in front of the valve housing (9) there are provided passages (16) through which contaminations entering into the receiving bore (2) along the bit shaft (3) can be discharged in outward direction before they can arrive at the valve seat (11). The shaft (12) of the valve cone (10) is preferably guided within the valve housing (9), so that contaminations are rinsed in outward direction through the passages (16) by the leakage water flowing therethrough.
    • 一种装有喷射装置的钻头架,包括容纳孔(2),钻头轴(3)被支撑在其中,用于有限的轴向移动运动并且可选地被旋转,钻头轴(3)沿着 切割压力由邻接(5)限制,并且钻头轴通过与切割压力相反的方向的返回力加载;以及阀(10,11),用于向钻头或工作或漂移面提供水 在切割操作期间布置在钻头保持器(1)内并且通过钻头轴(3)的轴向移动运动在切割压力的作用下打开。 阀壳体(9)插入到容纳孔(2)中。 钻头轴(3)的后端直接作用在阀锥(10)的轴(12)上。 在接收孔(2)的外壳内和阀壳体(9)的前面,设有通道(16),沿着钻头轴(3)进入接收孔(2)的污染物可通过该通道向外排放 方向才能到达阀座(11)。 阀体(10)的轴(12)优选地在阀壳体(9)内引导,使得污染物通过通过(16)的流动通过流过其中的泄漏水在向外的方向上被漂洗。
