Abstract
The utility model belongs to a coal rock breaking tool and particularly relates to a composite bit of a mining machine. The composite bit comprises a bit sleeve and a bit body, wherein the bit body consists of a bit head and a bit handle and is characterized in that the bit sleeve is sheathed at the periphery of the bit handle; the bit head and the bit handle are forged into one; a conical alloy head is arranged at the end part of the bit head; the conical alloy head and the bit head are inlayed into one; an annular groove is arranged on the bit handle; and a drum spring is arranged on the annular groove. The composite bit has better toughness and longer service life, can reduce the consumption and lowers the coal production cost.
Description
Technical field:
The utility model belongs to brokenly the coal petrography instrument, is mainly used in the colliery digger, is specifically related to a kind of compound digger pick.
Background technology:
In actual applications, the alloy head of existing pick collapses easily, and denticle hardness increases, and toughness reduces, fracture easily, thus make the application life of pick shorter.Cause ten thousand tons of consumptions bigger, increased the producing coal cost.
Summary of the invention:
The utility model aims to provide the compound digger pick that a kind of toughness is better, application life is long.
The realization the technical solution of the utility model is: comprise tooth cover, denticle, denticle is made of tooth head, tooth handle, it is characterized in that it is one that tooth head and tooth handle forge, the tooth cover is enclosed within the periphery of tooth handle, the tooth cephalic par is provided with taper alloy head, taper alloy head and tooth head are embedded as a whole, and the tooth handle is provided with an annular groove, and annular groove is provided with a spring.
The utility model toughness is better, application life is longer, can reduce by ten thousand tons of consumptions, reduces the producing coal cost.
Description of drawings:
Fig. 1 is that tooth head and tooth handle forge and be the structure chart of one among the utility model embodiment.
Fig. 2 is the structure chart of tooth cover among the utility model embodiment.
Among the figure: 1. taper alloy head; 2. tooth head; 3. tooth handle; The tube spring; 5. tooth cover.
The specific embodiment:
Embodiment: Fig. 1, shown in Figure 2, present embodiment comprises tooth cover 5, tooth head 2, tooth handle 3, it is characterized in that tooth cover 5 is enclosed within the periphery of tooth handle 3, tooth head 2 forges with tooth handle 3 and is one, the end of tooth head 2 is provided with taper alloy head 1, and taper alloy head 1 is embedded as a whole with tooth head 2, and tooth handle 3 is provided with an annular groove, annular groove is provided with a spring 4, tooth handle 3 rotations relatively of tube spring 4.
