Abstract
The invention relates to a waist belt structure for a reamer. The waist belt structure comprises a waist belt in an annular structure, the inner wall of the waist belt is symmetrically provided with a plurality of welding grooves, the outer wall of the waist belt is provided with a plurality of reaming strips, and an alloy block is arranged between each two adjacent reaming strips. The section of each reaming strip is in a trapezoid-like structure with a narrow bottom side and a wide bottom side, each wide bottom side is fixedly connected with the waist belt, and two lateral sides of each reaming strip are provided with flow guide grooves respectively. The waist belt structure for the reamer is structurally simple. Compared with a traditional waist belt for the reamer, the waist belt structure for the reamer has the advantages that by means of combination of the reaming strips and the alloy blocks, reaming efficiency is greatly improved; by arrangement of the welding grooves, convenience in welding onto a connection rod is achieved, and connection strength is improved; owing to the flow guide grooves formed in the reaming strips, reaming efficiency is improved while reaming resistance is reduced.
Description
Technical field
The present invention relates to geological prospecting apparatus field, particularly relate 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.
Summary of the invention
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 solution adopted in the present invention 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.
Beneficial effect of the present invention is as follows:
Structure of the present invention 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 invention.
Fig. 2 is front view of the present invention.
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, the specific embodiment of the present invention 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 invention 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 explanation of the invention, and be not the restriction to invention, limited range of the present invention is see claim, and when without prejudice to spirit of the present invention, the present invention can do any type of amendment.
