Description
Technical field
The utility model relates to geological prospecting apparatus field, particularly relates to reamer.
Background technology
Reamer is the instrument for reaming in geological prospecting, comprises waistband and drilling rod, and drilling rod is arranged at the center of waistband, and both are connected by connecting rod, and waistband is circulus, and connecting rod welds with the inwall of waistband and is connected.The shortcoming that waistband of the prior art exists is: the inwall of waistband is inconvenient with the welding operation of connecting rod, stable connection is not high; The outer wall of waistband does not arrange fraising structure, and the reaming efficiency of whole reamer is not high.
Utility model content
The shortcoming that the applicant exists for above-mentioned prior art, carries out studying and improving, provides a kind of Waistband structure of reamer, stable connection between itself and connecting rod, have fraising function, improves the reaming efficiency of reamer.
The technical scheme that the utility model adopts is as follows:
A Waistband structure for reamer, comprises the waistband of circulus, and the inwall of described waistband is symmetrical with multiple welding groove, and the outer wall of waistband is provided with many fraising bars, is provided with alloy block between adjacent fraising bar.
Further improvement as technique scheme:
Described welding groove is square groove structure.
The inclined of the relative waistband of described fraising bar is arranged.
The cross section of described fraising bar is the class trapezium structure with narrow base and wide base, and wide base and waistband are connected, and the two sides of fraising bar are respectively with guiding gutter.
The beneficial effects of the utility model are as follows:
Structure of the present utility model is simple, compares the waistband of traditional reamer, adopts fraising bar to combine with alloy block, greatly improves reaming efficiency; Welding groove structure is set, is convenient to weld with connecting rod, and improves bonding strength; Fraising bar is provided with guiding gutter, improves fraising efficiency and reduce fraising resistance.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model.
Fig. 2 is front view of the present utility model.
Fig. 3 is the A place partial enlarged drawing of Fig. 1.
In figure: 1, waistband; 2, ream bar; 21, guiding gutter; 22, narrow base; 23, wide base; 3, alloy block; 4, groove is welded.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1 to Figure 3, the Waistband structure of the reamer of the present embodiment, comprises the waistband 1 of circulus, and the inwall of waistband is symmetrical with multiple welding groove 4, and welding groove 4 is square groove structure, is beneficial to boxed rod and welds with it; The outer wall of waistband 1 is provided with many fraising bars 2, and the inclined of the relative waistband 1 of fraising bar 2 is arranged, and is provided with alloy block 3 between adjacent fraising bar 2.
The cross section of fraising bar 2 is with the class trapezium structure of narrow base 22 with wide base 23, wide base 23 is connected with waistband 1, the two sides of fraising bar 2 are respectively with guiding gutter 21, guiding gutter 21 1 aspect is for increasing the corner angle of fraising bar 2, improve its fraising efficiency, be used for diversion on the other hand, reduce fraising resistance.
Structure of the present utility model is simple, compares the waistband of traditional reamer, adopts fraising bar to combine with alloy block, greatly improves reaming efficiency; Welding groove structure is set, is convenient to weld with connecting rod, and improves bonding strength; Fraising bar is provided with guiding gutter, improves fraising efficiency and reduce fraising resistance.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range is see claim, and when without prejudice to spirit of the present utility model, the utility model can do any type of amendment.
