Abstract
The invention relates to a novel reamer. The novel reamer comprises a waistband body, the center of the waistband body is fixedly connected with a drill rod by the aid of a crossbar, a plurality of reaming rods are fixedly connected between the waistband body and the drill rod and are symmetrically arranged relative to the center of the drill rod, the drill rod, the reaming rods and the crossbar are of hollow structures, and the waistband body comprises two waistband rings arranged at intervals from top to bottom. A plurality of support plates are connected between the inner side walls of the lower ends of the support plates are provided with welding grooves, the upper ends of the reaming rods are fixedly welded in the welding grooves, and the sections of the reaming rods are of square structures. A plurality of reamed hole drums symmetrically arranged relative to the center of the waistband body are rotationally connected between the upper and lower waistband rings, alloy blocks are uniformly distributed on the outer walls of the reamed hole drums as well as the outer walls of the reaming rods.
Description
Technical field
The present invention relates to geological prospecting apparatus field, particularly relate to reamer.
Background technology
In prior art, there is following shortcoming in reamer: the reaming bar of reamer is cylindrical structural, the friction of itself and earth rubble is less, not enough to the shred-ability of earth rubble, there is relatively large earth rubble easily stuck in the middle of waistband and cross bar, cause reamer and other parts damages, cause feeding efficiency low; Bonding area between reaming bar and waistband inwall is little, and weld strength is not high; Waistband only plays a supportive role, and without fraising function, reaming efficiency is low; The reaming resistance of reamer is large, 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, provides a kind of novel reamer, and it has, and reaming is effective, reaming efficiency is high, the feature of stable connection.
The technical solution adopted in the present invention is as follows:
A kind of novel reamer, comprise belt body, the center of belt body to be connected drilling rod by cross bar, many reaming bars are fixed with between belt body and drilling rod, the relative drilling rod Central Symmetry of reaming bar is arranged, drilling rod, reaming bar and cross bar are hollow-core construction, described belt body comprises upper and lower spaced belt loop, polylith gripper shoe is connected with 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; Be rotatably connected to multiple fraising cylinder arranged about shown belt body Central Symmetry 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 effect 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 relative traditional cylindrical structure, improves the frictional force to saprolite ore, and raising blends, reaming effect; Adopt fraising roller frame, reduce reaming resistance, improve reaming efficiency and reaming quality; Waistband arranges welding groove structure, is convenient to weld with reaming bar, and improves bonding strength.

Fig. 3 is the three-dimensional structure diagram of waistband of the present invention.
In figure: 1, belt loop; 11, those widened sections; 2, gripper shoe; 21, groove is welded; 3, alloy block; 4, ream 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.
As Fig. 1, shown in Fig. 2 and Fig. 3, the novel reamer of the present embodiment, comprise belt body, the center of belt body to be connected drilling rod 5 by cross bar 6, many reaming bars 7 are fixed with between belt body and drilling rod 5, reaming bar 7 relatively drilling rod 5 Central Symmetry is arranged, drilling rod 5, reaming bar 7 and cross bar 6 are hollow-core construction, belt body comprises upper and lower spaced belt loop 1, polylith gripper shoe 2 is connected with 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, be rotatably connected to multiple fraising cylinder 4 arranged about shown belt body Central Symmetry 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 is rotated thereupon, and in rotation process, fraising cylinder 4 also self rotates around the center rotating of belt body, realizes fraising, and its fraising resistance is little, and bore edges planeness 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 relative traditional cylindrical structure, improves the frictional force to saprolite ore, and raising blends, reaming effect; Adopt fraising roller frame, reduce reaming resistance, improve reaming efficiency and reaming quality; Waistband arranges welding groove structure, is convenient to weld with reaming bar, and improves bonding strength.
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.
