Description
Technical field
The present invention relates to geological prospecting apparatus field, particularly relate to reamer.
Background technology
In prior art, reamer has the disadvantage in that the reaming bar of reamer is cylindrical structural, its with
The friction of earth rubble is less, not enough to the shred-ability of earth rubble, there is relatively large earth rubble easy
Middle stuck at belt and cross bar, cause reamer and other parts damages, cause feeding efficiency low；Reaming
Bonding area between bar and belt inwall is little, and weld strength is the highest；Belt only plays a supportive role, without hinged
Hole function, reaming efficiency is low.
Summary of the invention
The shortcoming that the applicant exists for above-mentioned prior art, studies and improves, it is provided that a kind of band subtracts
The reamer of resistance fraising formula belt, it has, and reaming is effective, reaming efficiency high, the feature of stable connection.
The technical solution adopted in the present invention is as follows:
The reamer of a kind of band drag reduction fraising formula belt, including the belt of ring-shaped structure, the center of belt is borrowed
Helping cross bar to be connected drilling rod, be fixed with many reaming bars between the inwall of belt and the sidewall of drilling rod, reaming bar is relative
Drilling rod is centrosymmetrically arranged, and drilling rod, reaming bar and cross bar are hollow-core construction, and the inwall of described belt is symmetrical
With multiple welding grooves, the upper end of reaming bar is welded in described welding groove, the cross section side of being of reaming bar
Shape structure；The outer wall of belt is provided with many fraising bars, with along fraising bar on the belt of fraising bar both sides
The gutter arranged, is provided with alloy block group between adjacent fraising bar, described alloy block group includes many edges
The alloy block that fraising bar is arranged；The outer wall of described reaming bar is evenly equipped with alloy block.
Further improvement as technique scheme:
The cross section of described fraising bar is the class trapezium structure with narrow base with wide base, and wide base is solid with belt
Even, the two sides of fraising bar are respectively provided with guiding gutter.
Described fraising bar is arranged relative to the inclined of belt.
Described welding groove is square groove structure.
Beneficial effects of the present invention is as follows:
During the present invention uses, due to the reaming bar of square structure, the reaming of relatively conventional cylindrical structural
Bar, improves the frictional force to saprolite ore, and raising blends, reaming effect；Belt uses fraising bar and conjunction
Gold bullion combines, and is greatly improved reaming efficiency；Belt arranges welding groove structure, it is simple to weld with reaming bar,
And improve bonding strength；Alloy block is set on cross bar, increases and rub function, improve the expansion of reamer further
Hole efficiency；The guiding gutter arranged on fraising bar combines with the gutter of belt, reduces fraising resistance, raising
Fraising efficiency.

Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described.
As shown in Figure 1, Figure 2 and Figure 3, the reamer of the band drag reduction fraising formula belt of the present embodiment, including
The belt 1 of ring-shaped structure, the center of belt 1 is connected drilling rod 5 by cross bar 6, the inwall of belt 1 with
Being fixed with many reaming bars 7 between the sidewall of drilling rod 5, the relative drilling rod 5 of reaming bar 7 is centrosymmetrically arranged, and expands
Vent stem 7 is square bar structure, is beneficial to rub clod, and drilling rod 5, reaming bar 7 and cross bar 6 are hollow-core construction,
The inner space of three, its outer wall is evenly equipped with apopore (not shown)；The inwall of belt 1 is symmetrical with many
Individual welding groove 4, the upper end of reaming bar 7 is welded in welding groove 4, and the outer wall of belt 1 is provided with many
Root is about its bar 2 that reams, with the gutter arranged along fraising bar 2 on the belt 1 of fraising bar 2 both sides
8, it is provided with alloy block group between adjacent fraising bar 2, alloy block group includes that many are arranged along fraising bar 2
Alloy block 3；The outer wall of cross bar 6 and reaming bar 7 is evenly equipped with alloy block 3.
Reaming bar 7 is square bar structure, and welding groove 4 is corresponding square groove structure, welds groove 4
Groove bottom be planar structure, contact for face with reaming bar 7, improve weld strength.
As shown in Figure 4, the cross section of fraising bar 2 is the class trapezium structure with narrow base 22 with wide base 23,
Wide base 23 is connected with belt 1, and the two sides of fraising bar 2 are respectively provided with guiding gutter 21, guiding gutter 21
On the one hand for increasing the corner angle of fraising bar 2, improve its fraising efficiency, on the other hand tie with gutter 8 phase
Close, for diversion, reduce fraising resistance.
During the present invention uses, due to the reaming bar of square structure, the reaming of relatively conventional cylindrical structural
Bar, improves the frictional force to saprolite ore, and raising blends, reaming effect；Belt uses fraising bar and conjunction
Gold bullion combines, and is greatly improved reaming efficiency；Belt arranges welding groove structure, it is simple to weld with reaming bar,
And improve bonding strength；Alloy block is set on cross bar, increases and rub function, improve the expansion of reamer further
Hole efficiency；The guiding gutter arranged on fraising bar combines with the gutter of belt, reduces fraising resistance, raising
Fraising efficiency.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention is joined
Seeing claim, in the case of the spirit of the present invention, the present invention can make any type of amendment.
