[0003] Geological exploration mainly includes pits, trenches, drilling, geophysical exploration and other methods. Drilling refers to the use of a drill to drill holes in the strata to identify and divide the subsurface strata and to take samples along the depth of the hole. Drilling is the most widely used exploration method in engineering geological surveys, and it can obtain deep geological data.

[0031] Example 1

[0032] like Figure 1-Figure 3 As shown:

[0033] A reamer for geological exploration comprises a bracket 1, on which a liftable reaming mechanism is mounted, the reaming mechanism comprises a main shaft 3, a rotating reaming portion 31 is mounted at the bottom end of the main shaft 3, and a retractable support plate 7 is mounted on the side wall of the main shaft 3.

[0034] The bracket 1 includes a top plate 11 and four side rods 12. The top of the side rod 12 is set at the edge of the top plate 11. The top plate 11 is connected to a lifting plate 2 through a lifting cylinder 15. The fixed end of the lifting cylinder 15 is installed on the bottom surface of the top plate 11, and the lifting plate 2 is connected to the telescopic end of the lifting cylinder 15.

[0035] In this embodiment, the lifting cylinder 15 is used as the first reciprocating drive device. A reciprocating drive device such as a hydraulic cylinder or an electric push rod may also be used to replace the lifting cylinder 15.

[0036] A guide groove 14 is formed on the inner wall of the side rod 12 , and a guide block 21 extending into the guide groove 14 is installed at a position of the lifting plate 2 close to the side rod 12 . The guide groove 14 is slidably connected to the guide block 21 .

[0037] The cross section of the guide groove 14 is T-shaped, and the cross section of the guide block 21 is T-shaped, which ensures that the guide block 21 always moves in the guide groove 14 and can avoid movement deviation of the lifting plate 2 during the lifting process.

[0038] The guide mechanism composed of the guide groove 14 and the guide block 21 can ensure that the hole expansion assembly is stable and smooth during the lifting process, avoiding uneven force or shaking.

[0039] A moving wheel 13 is installed at the bottom of the side rod 12, and a fixing plate is provided at a position of the outer wall of the side rod 12 near the bottom, and a fixing nail 16 is threadedly connected to the fixing plate, and the fixing nail 16 is vertically arranged.

[0040] The main shaft 3 is fixedly mounted on the lifting plate 2 .

[0041] A connecting groove 32 is formed on the top surface of the rotating expansion hole portion 31 , and the bottom of the main shaft 3 is inserted into the connecting groove 32 , so that the main shaft 3 is rotatably connected to the connecting groove 32 .

[0042] The outer wall of the main shaft 3 is sleeved with a connecting sleeve 34 installed on the top surface of the rotating reaming part 31, and the top inner wall of the connecting sleeve 34 is provided with a limiting ring 37. The outer wall of the main shaft 3 is provided with an annular groove 35 matching the limiting ring 37, and the rotating reaming part 31 is rotatably connected to the main shaft 3 through the connecting sleeve 34.

[0043] An outer gear ring 36 is installed on the outer wall of the connection, a rotating motor 41 is installed on the main shaft 3, a mounting plate 43 is provided on the main shaft 3, the rotating motor 41 is installed on the mounting plate 43, the output shaft of the rotating motor 41 passes through the mounting plate 43 and is connected to a driving gear 42 meshing with the outer gear ring 36, the output shaft of the rotating motor 41 is rotatably connected to the mounting plate 43, the driving gear 42 is driven by the rotating motor 41 to rotate, and then the outer gear ring 36 meshing with the driving gear 42 rotates, and the outer gear ring 36 drives the connecting sleeve 34 and the rotating reaming part 31 to rotate to perform the reaming work.

[0044] The rotating hole expanding part 31 is a stepped conical structure, which facilitates the rotating hole expanding part 31 to extend into the foundation hole and expand the hole step by step. The outer peripheral surface of the rotating hole expanding part 31 is provided with evenly arranged hole expanding nails 33.

[0045] The outer wall of the connecting sleeve 34 is connected to the support plate 7 through a scissor-type mechanism. The scissor-type mechanism includes a base 5 and a telescopic cylinder 53 installed on the outer wall of the connecting sleeve 34. A first slide groove 51 is provided on the outer side surface of the base 5, and a first slider 52 is provided in the first slide groove 51. A second slide groove 71 is provided on the inner side surface of the support plate 7, and a second slider 72 is provided in the second slide groove 71. A cross-hinged first hinged rod 61 and a second hinged rod 62 are provided between the base 5 and the support plate 7. One end of the first hinged rod 61 is rotatably connected to the base 5, and the other end is rotatably connected to the second slider 72.

The telescopic cylinder 53 is installed on the outer wall of the connecting sleeve 34, and the telescopic end of the telescopic cylinder 53 is connected to the first slider 52.

[0046] The telescopic cylinder 53 is extended and retracted to make the first slider 52 and the second slider 72 slide in the first slide groove 51 and the second slide groove 71 respectively, so that the scissor mechanism drives the support plate 7 to extend outward and retract inward. When the support plate 7 extends outward, it contacts the hole wall after the hole is expanded, providing support for the hole wall and preventing the soil or stone on the hole wall from collapsing.

[0047] In this embodiment, the telescopic cylinder 53 is used as the second reciprocating drive device. A reciprocating drive device such as a hydraulic cylinder or an electric push rod may also be used to replace the telescopic cylinder 53.

[0048] The outer surface of the support plate 7 is provided with a hole expansion texture, and the hole expansion texture acts on the hole wall. As the support plate 7 rotates with the connecting sleeve 34, the hole expansion work is further performed.

[0049] When the device is in use: the staff moves the device to the top of the foundation hole that needs to be expanded, and screws the fixing nail 16 so that the fixing nail 16 is inserted into the foundation to fix the device, and the expansion assembly is located above the foundation hole. The lifting cylinder 15 is started, driving the lifting plate 2 and the expansion assembly to descend, and the expansion assembly extends into the foundation hole; the rotating motor 41 is started, driving the rotating expansion part 31 to rotate, and through the cooperation of the lifting cylinder 15 and the rotating cylinder, the rotating expansion part 31 gradually expands the hole as it moves downward; the telescopic cylinder 53 is started, and the telescopic cylinder 53 drives the support plate 7 to extend outward, and the support plate 7 supports the hole wall to facilitate subsequent exploration operations.

[0050] The utility model has a simple structure and is easy to use. By arranging a retractable support plate 7, the hole wall after expansion is effectively supported to prevent the hole from collapsing, and effectively avoids the situation in which the expansion mechanism is buried due to the hole collapse and affects the geological exploration.

[0051] Example 2

[0052] like Figure 4 As shown, a guard plate 73 is installed on the support plate 7, and the guard plate 73 is tilted outward. The bottom of the guard plate 73 is connected to the top of the support plate 7. The setting of the guard plate 73 protects the scissor mechanism to prevent soil or stone from the hole wall from falling to the vicinity of the scissor mechanism, making it difficult for the scissor mechanism to extend and retract, thereby avoiding affecting the contraction of the support plate 7.

[0053] Example 3

[0054] like Figure 5 and Figure 6 As shown, the main shaft 3 of the device is hollow, a conveying bin is opened inside the main shaft 3, a screw conveyor 81 is arranged inside the conveying bin, the screw shaft of the screw conveyor 81 is rotatably connected to the internal space of the main shaft 3, the top of the screw shaft is connected to the output shaft of the conveying motor 82, and the bottom of the screw shaft is rotatably connected to the bottom wall of the connecting groove 32 of the rotating expansion part 31.

[0055] A discharge port 83 is provided on the side wall of the main shaft 3 near the top end. The discharge port 83 is located above the lifting plate 2. The discharge port 83 is communicated with the conveying bin, and the discharge port 83 is arranged to be inclined downward.

[0056] A spiral groove 84 is provided on the outer wall of the rotating hole expansion part 31 , and the upper end of the spiral groove 84 is connected to the through groove opened inside the rotating hole expansion part 31 , and the top end of the through groove is a soil material outlet 85 provided on the bottom wall of the connecting groove 32 .

[0057] During the hole expansion process, the soil falls below the rotating hole expansion part 31. In the process of the rotating hole expansion part 31 rotating downward to expand the hole, the soil is squeezed into the spiral groove 84, enters the through groove through the spiral groove 84, and enters the conveying bin from the soil outlet 85. The soil is transported to the top by the screw conveyor 81 and discharged from the discharge outlet 83, thereby avoiding excessive accumulation of soil below the rotating hole expansion part 31, which may cause blockage of the foundation hole and affect the hole expansion work.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
