Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology in geological exploration, specifically a portable geological exploration sampling device. Background Technology

[0002] When exploring geological conditions, it is necessary to sample soil and rock strata, and then test and analyze the obtained samples to obtain the type and content of minerals in the soil or rock strata. Existing geological and mineral exploration sampling equipment is bulky and complex in structure, which is completely impractical for geological and mineral exploration sampling close to the surface. Moreover, existing sampling equipment is not convenient to transport and carry, and is not suitable for geological and mineral exploration sampling in remote areas, high mountains and other environments. Furthermore, it is not easy to fix the equipment when pressing it into the soil layer, and drilling may cause tilting, which has certain adverse effects.

[0003] To address the above problems, this utility model is proposed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a portable geological exploration sampling device to solve the problems mentioned in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0006] This utility model provides a portable geological exploration sampling device, including an outer tube, an inner insertion column, and an outer ring. The inner insertion column is slidably installed inside the outer tube, and the outer ring is slidably installed on the outer surface of the outer tube.

[0007] A motor is vertically mounted at the lower end of the inner insert post. The drive shaft of the motor faces downward. A receiving cylinder is mounted on the drive shaft of the motor via a pin. The lower surface of the receiving cylinder is open. A drill bit is threaded onto the lower surface of the receiving cylinder. The surface of the receiving cylinder is provided with multiple through holes that communicate with the interior of the receiving cylinder.

[0008] The outer ring has a second pin hole on its surface, and the outer tube has a plurality of first pin holes on its surface from bottom to top. The second pin holes are aligned with the first pin holes. The outer ring has a plurality of sets of rotating seats on its surface, and a support leg is rotatably mounted between each set of rotating seats.

[0009] Preferably, the surface of the inner insert post is provided with four sliding strips, which are evenly distributed around the surface of the inner insert post at equal intervals. Each sliding strip is arranged along the length direction of the inner insert post. The inner wall of the outer sleeve is provided with a sliding groove, and the sliding strip is slidably installed in the sliding groove.

[0010] Preferably, the upper end of the inner insert post is symmetrically provided with two handles, the outer diameter of the inner insert post is the same as the inner diameter of the outer sleeve, and the outer diameter of the outer sleeve is the same as the inner diameter of the outer ring.

[0011] Preferably, the four sets of rotating seats are evenly distributed around the surface of the outer ring at equal intervals, and the upper end of the support leg is rotatably mounted between the rotating seats, while the lower end is provided with an anti-slip sleeve.

[0012] Preferably, the through holes are arranged in multiple layers at equal intervals from bottom to top, with multiple through holes in each layer, and the multiple through holes in each layer are evenly distributed around the surface of the receiving cylinder at equal intervals.

[0013] Preferably, the upper surface of the receiving cylinder is provided with a hoop, which is sleeved on the drive shaft end of the motor.

[0014] Preferably, there are four second pin holes evenly distributed around the outer ring at equal intervals, and four rows of first pin holes evenly distributed around the surface of the outer tube at equal intervals.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When you reach the specific geological sampling location, slide the outer ring to the appropriate position and open the four legs so that the four legs can support the sampling location. At this time, the drill bit is just above the sampling point. Then use pins to insert into the second pin hole and the first pin hole to fix the outer ring and the four legs.

[0017] The operator holds the handle and pushes it downwards, which moves the inner insert and the motor below downwards. The four slide bars guide the movement of the inner insert, so that the inner insert, motor, container and drill bit are relatively stable during the up and down movement.

[0018] When the motor is working, it can drive the container and the drill bit to rotate. When the motor moves downward, the drill bit can drill into the soil, and the container also enters the drilled hole. During the process of the container and the drill bit drilling downward, the soil at the drilling point can enter the container through the through hole and be stored in the container.

[0019] After drilling at the sampling location, the container and drill bit are disassembled from the drive shaft of the motor, and the drill bit threads are unscrewed. This allows the soil sample collected in the container to be taken out and placed in the storage bag. When the four legs are folded, the entire device is easy to move and is particularly suitable for soil sampling during field geological exploration. Attached Figure Description

[0027] like Figure 1-4 As shown, a portable geological exploration sampling device includes an outer tube 1, an inner insertion post 2, and an outer ring 3. The inner insertion post 2 is slidably installed inside the outer tube 1, and the outer ring 3 is slidably installed on the outer surface of the outer tube 1.

[0028] A motor 23 is vertically installed at the lower end of the inner insert post 2. The drive shaft end of the motor 23 faces downward. A receiving cylinder 24 is installed at the drive shaft end of the motor 23 through a pin. The lower surface of the receiving cylinder 24 is open. A drill bit 25 is threadedly connected to the lower surface of the receiving cylinder 24. A plurality of through holes 241 communicating with the interior of the receiving cylinder 24 are provided on the surface of the receiving cylinder 24.

[0029] The outer ring 3 has a second pin hole 33 on its surface, and the outer tube 1 has a plurality of first pin holes 11 on its surface from bottom to top. The second pin hole 33 is aligned with the first pin hole 11. The outer ring 3 has a plurality of sets of rotating seats 31 on its surface, and each set of rotating seats 31 has a support leg 32 rotatably mounted between them.

[0030] The inner insert post 2 has four sliding strips 21 on its surface. The four sliding strips 21 are evenly distributed around the surface of the inner insert post 2 at equal intervals. Each sliding strip 21 is arranged along the length of the inner insert post 2. The inner wall of the outer sleeve 1 is provided with a sliding groove, and the sliding strip 21 is slidably installed in the sliding groove.

[0031] Two handles 22 are symmetrically arranged on the upper end of the inner insert post 2. The outer diameter of the inner insert post 2 is the same as the inner diameter of the outer sleeve 1, and the outer diameter of the outer sleeve 1 is the same as the inner diameter of the outer sleeve ring 3.

[0032] Four sets of rotating seats 31 are evenly distributed around the surface of the outer ring 3 at equal intervals. The upper end of the support leg 32 is rotatably installed between the rotating seats 31, and the lower end is provided with an anti-slip sleeve.

[0033] The through holes 241 are arranged in multiple layers at equal intervals from bottom to top. Each layer has multiple through holes 241, and the multiple through holes 241 in each layer are evenly distributed around the surface of the receiving cylinder 24 at equal intervals.

[0034] The upper surface of the receiving cylinder 24 is provided with a hoop, which is fitted onto the drive shaft end of the motor 23.

[0035] There are four second pin holes 33, which are evenly distributed around the outer ring 3 at equal intervals. There are four rows of first pin holes 11, which are evenly distributed around the surface of the outer tube 1 at equal intervals.

[0036] In summary: When reaching the specific geological sampling location, slide the outer ring 3 to the appropriate position, open the four legs 32 so that the four legs 32 can support the sampling location. At this time, the drill bit 25 is just above the sampling point. Then, use a pin to insert into the second pin hole 33 and the first pin hole 11. In this way, the outer ring 3 and the four legs 32 are fixed.

[0037] The operator holds the handle 22 and pushes it downwards, which can move the inner insert 2 and the motor 23 below downwards. The four slide bars 21 guide the movement of the inner insert 2, so that the inner insert 2, motor 23, receiving cylinder 24 and drill bit 25 are relatively stable during the up and down movement.

[0038] When the motor 23 is working, it can drive the container 24 and the drill bit 25 to rotate. When the motor 23 moves downward, the drill bit 25 can drill into the soil, and the container 24 also enters the drilled hole. During the process of the container 24 and the drill bit 25 drilling downward, the soil at the drilling point can enter the container 24 through the through hole 241 and be stored in the container 24.

[0039] After drilling at the sampling location is completed, the container 24 and drill bit 25 are disassembled from the drive shaft end of the motor 23, and the drill bit 25 is unscrewed. This allows the soil sample collected in the container 24 to be taken out and placed in the storage bag. When the four support legs 32 are retracted, the entire device is easy to move and is particularly suitable for soil sampling during field geological exploration.

[0040] The above are preferred embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
