Description

Technical Field

[0001] The utility model relates to the field of geological exploration, in particular to a hole expander for geological exploration. Background Art

[0002] Geological exploration can be broadly understood as geological work. It is an investigation and research work on the geological conditions such as rocks, stratigraphic structures, minerals, groundwater, landforms, etc. in a certain area based on the needs of economic construction, national defense construction and scientific and technological development, using geological exploration methods such as surveying and mapping, geophysical exploration, geochemical prospecting, drilling, pit exploration, sampling testing, geological remote sensing, etc. Usually, drilling and drilling are carried out using drill bits of different diameters.

[0003] However, the current post-drilling hole expansion process mostly uses a large drill bit to re-drill the hole. Since the center of the hole is inconvenient to find, direct hole expansion is likely to cause hole position deviation. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a reamer for geological survey, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: a reamer for geological exploration, comprising a reamer, a centering mechanism is arranged at the bottom of the reamer, an upper connecting seat is arranged inside the centering mechanism, a centering plug plate is arranged on the outer annular array of the upper connecting seat, a three-jaw chuck is installed on the lower surface of the upper connecting seat, a limiting slide groove is provided on the annular array on the lower surface of the three-jaw chuck, a clamping slider is installed on the inner side of the limiting slide groove, a threaded tooth disk is installed on the inside of the three-jaw chuck above the clamping slider, a bevel gear is installed on the inner side of the three-jaw chuck above the threaded tooth disk, and an adjusting rotary rod is installed on the inner side of the bevel gear.

[0006] As a further solution of the utility model: a second screw is installed on the inner wall of the centering plug plate, a first screw is installed on the outer side of the upper connecting seat at a position corresponding to the second screw, and an adjusting threaded barrel is sleeved on the outer sides of the first screw and the second screw.

[0007] As a further solution of the utility model: the lower end of the reaming machine is connected with a reaming drill bit via a rotating shaft.

[0008] As a further solution of the utility model: the clamping slide block and the limiting slide groove slide in a limited manner, and a meshing tooth block is installed on the lower surface of the threaded toothed disc at a position corresponding to the bevel gear.

[0009] As a further solution of the utility model: the clamping slider is meshed with the threaded toothed disc, and a through hole is provided at the center hole position of the three-jaw chuck corresponding to the center position of the circle of the upper connecting seat.

[0010] As a further solution of the utility model: the first screw and the second screw are both engaged and movable with the adjusting threaded barrel.

[0011] As a further solution of the utility model: the three-jaw chuck is fixedly connected to the upper connecting seat by bolts.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By applying torque to the adjusting rotary rod as a whole and controlling the internal sliding of the limiting groove of the threaded toothed disk driving the clamping slider as a whole, the center of the drill hole can be easily found after the drill bit is replaced, avoiding the deviation of the hole position after the hole is expanded.

[0014] By adjusting the threaded barrel as a whole to engage with the outside of the first screw and the second screw, the multiple centering plug plates are controlled to move synchronously away from the center position of the upper connecting seat as a whole, and then the centering plug plates are inserted into the ground again. A drill bit with a larger diameter can be placed on the inside of the centering mechanism to achieve multiple hole expansion processing of the hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1-5 As shown, the present embodiment provides a reamer for geological exploration, including a reamer 1, a centering mechanism 2 is arranged below the reamer 1, an upper connecting seat 3 is arranged inside the centering mechanism 2, a centering plug plate 4 is arranged in an annular array outside the upper connecting seat 3, a three-jaw chuck 7 is installed on the lower surface of the upper connecting seat 3, the three-jaw chuck 7 is fixedly connected to the upper connecting seat 3 by bolts, a through hole is provided at the center hole position of the three-jaw chuck 7 corresponding to the center position of the circle of the upper connecting seat 3, and a limited sliding groove 70 is provided in an annular array on the lower surface of the three-jaw chuck 7 4. A clamping slider 703 is installed on the inner side of the limiting slide groove 704. The clamping slider 703 and the limiting slide groove 704 slide in a limited manner. A threaded toothed disc 702 is installed above the clamping slider 703 and located inside the three-jaw chuck 7. The clamping slider 703 and the threaded toothed disc 702 are meshed and movable. A bevel gear 701 is installed on the inner side of the three-jaw chuck 7 above the threaded toothed disc 702. An engaging tooth block is installed on the lower surface of the threaded toothed disc 702 at the position corresponding to the bevel gear 701. An adjusting rotary rod 8 is installed inside the bevel gear 701.

[0023] like Figure 2-5 As shown, in this embodiment, a second screw 502 is installed on the inner wall of the centering plug plate 4, and a first screw 501 is installed on the outer side of the upper connecting seat 3 at a position corresponding to the second screw 502. An adjusting threaded barrel 5 is sleeved on the outer sides of the first screw 501 and the second screw 502. The first screw 501 and the second screw 502 are both engaged with the adjusting threaded barrel 5. The adjusting threaded barrel 5 is controlled to rotate on the outer sides of the first screw 501 and the second screw 502, so that the multiple centering plug plates 4 arranged in the adjustment array are synchronously expanded and reduced in diameter. The multiple centering plug plates 4 are used to position on the outer side of the drilled hole, and the lower end of the reaming machine 1 is connected to the reaming drill bit 6 through a rotating shaft.

[0024] The working principle of the utility model is as follows: when in use, the drill bit is first passed through the holes of the three-jaw chuck 7 and the upper connecting seat 3 and then installed under the reaming machine 1. After the multiple centering plug plates 4 under the centering mechanism 2 are inserted as a whole into the ground to be drilled, the clamping slider 703 inside the three-jaw chuck 7 is adjusted to contact the outside of the drill bit rotating rod, and the reaming machine 1 is controlled to drive the drill bit as a whole to perform drilling processing. After the operation is completed, when the reaming operation is required, the centering mechanism 2 and the reaming machine 1 are taken out as a whole, and the reaming drill bit 6 is installed as a whole at the lower position of the reaming machine 1 according to the above steps, and then the centering plug plate 4 is inserted into the slotted hole existing on the ground again, and the bevel gear 701 as a whole and the threaded rod 8 are controlled by applying torque to the adjusting rotary rod 8 as a whole. The toothed disc 702 engages and rotates, controlling the threaded toothed disc 702 to drive the clamping slider 703 to slide inside the limiting slide groove 704 as a whole, so that multiple clamping sliders 703 are in contact with the outer side of the rotating rod of the reaming drill bit 6 as a whole, and then the reaming machine 1 is driven to control the reaming drill bit 6 to reaming the excavated hole. When the reaming position needs to be excavated again, the reaming drill bit 6 is not removed first. After the centering mechanism 2 is pulled upward as a whole, the adjusting threaded barrel 5 is used to engage the outer side of the first screw rod 501 and the second screw rod 502 as a whole. After controlling multiple centering plug plates 4 to move away from the center position of the upper connecting seat 3 as a whole synchronously, the centering plug plates 4 are inserted into the ground again, and a drill bit with a larger diameter can be placed on the inner side of the centering mechanism 2.
