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, it is less with the friction of earth rubble, the shred-ability of earth rubble is not enough, there is relatively large earth rubble easily stuck in the middle of belt with cross bar, cause reamer and other parts damages, cause that feeding efficiency is low; Bonding area between reaming bar and belt inwall is little, and weld strength is not high; Belt only plays a supportive role, and without fraising function, reaming efficiency is low; The reaming resistance of reamer is big, and bore edges is comparatively coarse, is unfavorable for the drilling operation in later stage.
Summary of the invention
The shortcoming that the applicant exists for above-mentioned prior art, carries out studying and improving, it is provided that a kind of novel reamer, and 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:
A kind of novel reamer, including belt body, the center of belt body is by the connected drilling rod of cross bar, many reaming bars it are fixed with between belt body and drilling rod, the relative drilling rod centrosymmetry of reaming bar is arranged, drilling rod, reaming bar and cross bar are hollow-core construction, described belt body includes upper and lower spaced belt loop, polylith gripper shoe it is connected between two belt loops, the lower end inside cornice of gripper shoe has welding groove, the upper end welding of reaming bar is fixed in welding groove, and the cross section of reaming bar is square structure; Being rotatably connected to multiple fraising cylinder arranged about shown belt body centrosymmetry between upper and lower belt loop, the outer wall of fraising cylinder is evenly equipped with alloy block; The outer wall of described reaming bar is evenly equipped with alloy block.
Further improvement as technique scheme:
Described welding groove is square groove structure.
With those widened sections on described belt loop, rotate between upper and lower those widened sections and described fraising cylinder is installed.
Beneficial effects of the present invention is as follows:
In use procedure of the present invention, due to the reaming bar of square structure, the reaming bar of relatively conventional cylindrical structural, improve the frictional force to saprolite ore, raising blends, reaming effect;Adopt fraising roller frame, reduce reaming resistance, improve reaming efficiency and reaming quality; Belt arranges welding groove structure, it is simple to welds with reaming bar, and improves bonding strength.

Fig. 2 is another three-dimensional structure diagram of the present invention.
Fig. 3 is the three-dimensional structure diagram of the belt of the present invention.
In figure: 1, belt loop; 11, those widened sections; 2, gripper shoe; 21, welding groove; 3, alloy block; 4, fraising cylinder; 5, drilling rod; 6, cross bar; 7, reaming bar.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Such as Fig. 1, shown in Fig. 2 and Fig. 3, the novel reamer of the present embodiment, including belt body, the center of belt body is connected drilling rod 5 by cross bar 6, many reaming bars 7 it are fixed with between belt body and drilling rod 5, relative drilling rod 5 centrosymmetry of reaming bar 7 is arranged, drilling rod 5, reaming bar 7 and cross bar 6 are hollow-core construction, belt body includes upper and lower spaced belt loop 1, it is connected to polylith gripper shoe 2 between two belt loops 1, the lower end inside cornice of gripper shoe 2 has welding groove 21, the upper end welding of reaming bar 7 is fixed in welding groove 21, the cross section of reaming bar 7 is square structure, being rotatably connected to multiple fraising cylinder 4 arranged about shown belt body centrosymmetry between upper and lower belt loop 1, the outer wall of fraising cylinder 4 is evenly equipped with alloy block 3, the outer wall of reaming bar 7 is evenly equipped with alloy block 3. when reamer rotates reaming, belt body concomitant rotation, in rotation process, fraising cylinder 4 also self rotates around the center rotating of belt body, it is achieved fraising, and its fraising resistance is little, and bore edges flatness is high.
Welding groove 21 is square groove structure, and the groove bottom of welding groove 21 is plane, is beneficial to the bonding area increased with reaming bar 7, improves weld strength.
With those widened sections 11 on belt loop 1, rotate between upper and lower those widened sections 11 and fraising cylinder 4 is installed.
In use procedure of the present invention, due to the reaming bar of square structure, the reaming bar of relatively conventional cylindrical structural, improve the frictional force to saprolite ore, raising blends, reaming effect; Adopt fraising roller frame, reduce reaming resistance, improve reaming efficiency and reaming quality; Belt arranges welding groove structure, it is simple to welds with reaming bar, and improves bonding strength.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, and when without prejudice to the spirit of the present invention, the present invention can do any type of amendment.
