    • According to the present invention, a drill rod (10) comprises an elongate hollow shaft (12) with a first shaft end and a second shaft end (22), the first shaft end having a first connector for connecting the drill rod (10) to a drive mechanism, the second shaft end (22) having a first female tread (24); and an adapter (30) with a first adapter end (32) and a second adapter end (34), the first adapter end (32) having a first male thread (42) cooperating with the first female tread (24) of the second shaft end (22), the second adapter end (34) having a second connector for connecting a drill bit (46) thereto. When a drill bit (46) is connected to the drill rod (10), the adapter (30) is sandwiched between the hollow shaft (12) and the drill bit (46). The above configuration of drill rod allows a great variety of drill bits to be used in conjunction with a single hollow shaft. There is hence no need to provide a different hollow shaft if a different drill bit is to be used. Manufacturing costs of drill rods do hence not have to be considerably-increased if a variety of drill bits are to be used.
    • 根据本发明,钻杆(10)包括具有第一轴端和第二轴端(22)的细长空心轴(12),第一轴端具有用于连接钻杆(10)的第一连接器, 驱动机构,所述第二轴端(22)具有第一凹形胎面(24); 以及具有第一适配器端(32)和第二适配器端(34)的适配器(30),所述第一适配器端部(32)具有与所述第二适配器端部(32)的第一接合端(32)配合的第一阳螺纹 轴端(22),第二适配器端(34)具有用于将钻头(46)连接到其上的第二连接器。 当钻头(46)连接到钻杆(10)时,适配器(30)夹在中空轴(12)和钻头(46)之间。 钻杆的上述构造允许将多种钻头与单个中空轴结合使用。 因此,如果使用不同的钻头,则不需要提供不同的空心轴。 因此,如果要使用各种钻头,钻杆的制造成本因此不必大幅增加。

    • The invention relates to a device for distributing a material in a molten state, said device comprising a swinging chute (16) supported so as to be capable of swinging about a substantially horizontal swinging axis (25), and a driving group (40). The latter comprises gear motor group (42), a drum winch (44) driven by the gear motor group (42), and at least one cable segment (50, 50′) that can be both wound on or unwound from said drum. One end of the cable segment (46, 50, 50′) is attached to the swinging chute (16) at a distance L from the swinging axis (25) thereof so as to apply a swinging momentum to said swinging chute (16).
    • 本发明涉及一种用于在熔融状态下分配材料的装置,所述装置包括被支撑以能够围绕基本上水平的摆动轴线(25)摆动的摆动滑槽(16)和驱动组(40)。 后者包括齿轮马达组(42),由齿轮马达组(42)驱动的滚筒绞盘(44),以及可以从所述滚筒卷绕或退绕的至少一个缆线段(50,50')。 电缆段(46,50,50')的一端以与其摆动轴线(25)成距离L的方式安装在摆动滑槽(16)上,以向摆动滑槽(16)施加摆动动量。
