Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of ground mineral exploration devices, belong to surveying technical field. BACKGROUND

[0002] Ground mineral exploration (geological exploration) is to provide the mineral reserves and geological data required for mine construction design in the investigation of mineral resources, and to investigate and study the geological conditions of rock, stratum, structure, mineral resources, hydrology, geomorphology and other geological conditions in a certain area. In ground mineral exploration, drilling of geological soil and the like is often required, and a punching device is a common way.

[0003] The related art currently discloses a punching device including a punching drill bit, a driving machine, and a handrail. For example, the structure of a punching device for geotechnical exploration is disclosed in Chinese Utility Model No. 201820593585.6. However, this device requires two workers to hold the drilling machine and drill holes in the ground by pressing the handle downward to drive the drill bit downward. However, it requires a lot of effort to manually move the drill bit downward, and the drill bit vibrates strongly during drilling, making it difficult for workers to hold it. This drilling method is not suitable for long-term operation and is inconvenient to use, and it cannot meet the needs of deep hole drilling. Therefore, some existing technologies provide a frame outside the driving machine, and the driving machine and the punching drill bit are slidingly installed in the frame. A mechanism is provided on the frame to drive the driving machine and the punching drill bit to slide, thereby eliminating the need for manual support during drilling. However, the current device only relies on the sliding connection between the driving machine and the frame to simply limit the punching drill bit. Since the auger of the punching drill bit is relatively long, it cannot be well guided and limited, which may cause the auger to tilt during piling, affecting the quality of the drilling and causing the device to be worn to some extent.

[0004] In addition, during drilling, it is common practice to use a drill rod to drill directly into the ground to a certain depth. At this time, a portion of the soil is pressed into the drill rod. During the process of removing the drill rod after drilling into the soil, the drill rod brings out the soil core pressed into the drill rod. Manual knocking is required for cleaning, which not only consumes labor but also has low work efficiency. It is time-consuming and labor-intensive for workers to remove and clean the soil core inside the drill rod. If the soil core pressed into the drill rod is moist and compact, it is difficult to clean the soil core adhered to the inner wall of the drill rod. SUMMARY

[0030] Embodiment 1

[0031] As Figures 1-2As shown in the figure, a device for earth exploration includes a frame 1, a drill rod 2, a first driving mechanism 3 and a second driving mechanism 4, the first driving mechanism 3 and the second driving mechanism 4 are respectively installed on the frame 1, the first driving mechanism 3 is in sliding connection with the frame 1, the second driving mechanism 4 is connected with the first driving mechanism 3 and can drive the first driving mechanism 3 to slide up and down on the frame 1, the output end of the first driving mechanism 3 is provided with the drill rod 2, and the drill rod 2 is a screw rod, that is, a spiral blade is arranged on the drill rod 2. The exploration device provided in the embodiment further includes a limiting plate 5, a limiting sleeve 6 and a multifunctional spiral block 7; the limiting plate 5 is arranged at the lower part of the frame 1, and a certain distance is left between the limiting plate 5 and the lower end of the frame 1 for accommodating the drilled soil and the like. The limiting sleeve 6 is arranged on the limiting plate 5 and is in rotary connection with the limiting plate 5, and the multifunctional spiral block 7 is arranged in the limiting sleeve 6. Figure 4 As shown in the figure, the multifunctional spiral block 7 is a spiral structure (the spiral length of the multifunctional spiral block 7 is equal to the depth of the limiting sleeve 6) which is the same as the spiral blade on the drill rod 2 except for the spiral length, so that the drill rod 2 can be screwed into and out of the limiting sleeve 6, and the drill rod 2 is always kept in connection with the limiting sleeve 6 during the up-and-down sliding process of the first driving mechanism 3, preventing the two from being disconnected and then reconnected, which needs to spend a certain amount of time for alignment.

[0032] When the exploration device is used for drilling, the drill rod 2 is screwed into the limiting sleeve 6 during drilling, and when hard stratum is encountered and drilling cannot be carried out for a short time, the drill rod 2 is slowly drilled or even idles in place, which drives the limiting sleeve 6 to rotate together, preventing the multifunctional spiral block 7 from interfering with the rotation of the drill rod 2; when the drill rod 2 is withdrawn after drilling is completed, the multifunctional spiral block 7 scrapes off the soil core on the spiral blade of the drill rod 2.

[0033] In the embodiment, at least two multifunctional spiral blocks 7 are arranged in the limiting sleeve 6, and gaps are arranged between the multifunctional spiral blocks 7, so as to facilitate layered cleaning of the soil core brought out by the spiral blade of the drill rod 2.

[0034] In the embodiment, a soil removing tooth 8 is arranged at the lower end of the multifunctional spiral block 7, so as to facilitate crushing and cleaning of the soil core brought out by the spiral blade of the drill rod 2.

[0035] Embodiment 2

[0036] The embodiment is further refined on the basis of the arrangement of the limiting sleeve 6 in the embodiment 1, and specifically:

[0037] The limiting sleeve 6 is in one-way rotation, and the rotation direction is the rotation direction when the drill rod 2 drills, that is, when the drill rod 2 is withdrawn from the borehole, the limiting sleeve 6 does not rotate, thereby facilitating cleaning of the soil core brought out by the spiral blade of the drill rod 2.

[0038] The following is a structure in which the limiting sleeve 6 is configured to rotate in one direction:

[0039] The geological exploration device described in this embodiment also includes a stop mechanism 9, such as... Figure 6 As shown, the outer circumferential array of the limiting sleeve 6 is provided with densely arranged stop grooves 10. The stop grooves 10 are arranged along the axial direction of the limiting sleeve 6. The stop mechanism 9 is arranged on the limiting plate 5 on one side of the limiting sleeve 6. The stop mechanism 9 includes a base 11, a stop rod 12 and a return spring 13. The base 11 is installed on the limiting plate 5 by bolts. The stop rod 12 is slidably arranged on the base 11. The return spring 13 is arranged at one end of the stop rod 12, and the other end extends into the stop groove 10 under the action of the return spring 13. The end extending into the stop groove 10 is provided with a sloping guide surface 14. The sloping guide surface 14 is arranged on the side of the stop rod 12 that receives the limiting sleeve 6 as it rotates with the drill rod 2 during drilling (at the same time, in order to facilitate the smooth ejection of the stop rod 12, the side wall of the stop groove 10 that lifts the stop rod 12 can be set with the same sloping surface structure). As drill rod 2 drills into the formation, the limiting sleeve 6 may rotate with drill rod 2. During rotation, the wall of the stop groove 10 presses against the inclined guide surface 14 of the stop rod 12, causing the stop rod 12 to be pushed out of the stop groove 10. At this time, the return spring 13 is compressed, and the limiting sleeve 6 rotates one groove position. When it rotates to the next stop groove 10, the stop rod 12 extends into the stop groove 10 again under the action of the return spring 13, and is then pushed out again. During the rotation of the limiting sleeve 6, the stop rod 12 is continuously pushed out of the stop groove 10, thus not affecting the rotation of the limiting sleeve 6. When drill rod 2 finishes drilling and withdraws from the borehole, if the limiting sleeve 6 rotates with drill rod 2, it will be jammed by the stop rod 12, preventing it from rotating. This allows the multi-functional spiral block 7 inside the limiting sleeve 6 to scrape off the soil core on the spiral blades of drill rod 2 to the maximum extent.

[0040] In the above process, not only can the limiting sleeve 6 play a role in limiting and guiding the drill rod 2, but the multi-functional spiral block 7 also plays a certain role in limiting and guiding the drill rod 2, especially when the spiral blades on the drill rod 2 are in contact with the multi-functional spiral block 7.

[0041] Example 3

[0042] This embodiment is a further optimization and refinement of the stop rod 12 structure based on embodiment 2, specifically as follows:

[0044] In the embodiment, the height of the stopper block 15 and the height of the stopper groove 10 are not less than two-thirds of the height of the limiting sleeve 6, so that the stopper 12 and the stopper groove 10 have high structural strength, and better provide the limiting and stopping effect for the limiting sleeve 6, and at least two sliding rods 16 are arranged on the stopper block 15, thereby improving the overall structural strength of the stopper 12.
