Description

Technical Field

[0001] This utility model belongs to the field of sampling equipment technology, and in particular relates to a geological exploration sampling device. Background Technology

[0002] Geological sampling is a crucial step in geological exploration. By analyzing rock and soil samples, we can understand their mineral composition, structure, and other characteristics, and determine the rock type, such as distinguishing between granite and sandstone. For soil, we can determine its basic properties, such as texture (e.g., sandy soil, loam, clay).

[0003] Chinese patent announcement number CN211122083U discloses a geological exploration sampling device, which includes a cylindrical drill rod with a square through hole along its height. The bottom end of the drill rod is recessed inwards to form an inclined surface. Two opposite sides of the square through hole at the upper end of the inclined surface are recessed inwards to form a stop-block mounting cavity. A rotatable stop is provided at the upper end of the stop-block mounting cavity. A strip-shaped through hole is provided inside the drill rod, and a first connecting seat is fitted onto the stop. A first rope passing through the strip-shaped through hole is connected to the first connecting seat. The drill rod also has connecting through holes at both ends that communicate with the stop-block mounting cavity and the strip-shaped through hole, respectively. A second connecting seat is provided on the end face of the stop away from the first connecting seat, and a second rope passing through the connecting through hole and the strip-shaped through hole is connected to the second connecting seat. This invention improves sampling efficiency and sampling effect.

[0004] However, this device has the following drawbacks in use: when sampling soil, the drill rod needs to be forcefully inserted into the ground, but as the drill rod goes deeper into the soil, the contact area between the drill rod and the soil increases, making it difficult for the sampling rod to penetrate deep into the soil. To address these drawbacks, we propose a geological exploration sampling device. Utility Model Content

[0005] The purpose of this invention is to provide a geological exploration and sampling device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: a geological exploration sampling device, comprising:

[0007] A support frame, the support frame including a sleeve and a foot plate fixedly installed on the outer surface of the sleeve;

[0008] The sampling structure includes a nut seat fixedly installed on the inner wall of the sleeve, a threaded rod threadedly connected to the inner wall of the nut seat, and a sampler disposed at the lower end of the threaded rod.

[0009] The sampler includes a sampling cylinder, a digging head threaded to the lower end of the sampling cylinder, and an assembly assembly disposed between the sampling cylinder and the threaded rod;

[0010] The assembly components include a nut fixedly installed at the lower end of the threaded rod, and an external thread formed at the upper end of the sampling cylinder;

[0011] A sample core sleeve is disposed inside the sampling cylinder and is used for rapid sampling of the sample core.

[0012] Preferably, two extended handles are fixedly installed at the upper end of the threaded rod.

[0013] Preferably, there are two foot pedals, and the two foot pedals are symmetrically arranged on the surface of the sleeve.

[0014] Preferably, a pin is fixedly installed on the lower surface of the foot pedal.

[0015] Preferably, the sample core sleeve is composed of two interlocking first and second semicircular plates, and the sampling tube has an internal cavity that is compatible with the sample core sleeve.

[0016] Preferably, the lower end of the excavator head is provided with excavating teeth, and the inner wall of the excavator head is provided with through holes.

[0017] The geological exploration and sampling device of this invention has the following advantages:

[0018] 1. This geological exploration sampling device, through the setting of a support frame and sampling structure, first installs the sampler at the lower end of the threaded rod, then places the support frame in the sampling area. The sampling personnel can then fix the sleeve by stepping on the foot pedals. The sampling personnel can rotate the extended handle to drive the threaded rod to rotate. Utilizing the helical transmission between the threaded rod and the nut seat, the sampling cylinder and excavator head can move downwards evenly according to the pitch of the threaded rod while rotating. Compared with existing technologies, this device breaks away from the traditional method of inserting the sampler downwards into the soil. By utilizing the cooperation between the threaded rod and the nut seat, the sampler can be inserted into the soil while rotating. The excavator head generates tangential force during rotation, and a gap is created between the sampler and the soil after rotation, reducing friction. This allows the sampler to be inserted deeper into the soil more easily, making it less strenuous for the sampling personnel.

[0019] 2. This geological exploration sampling device uses a core sleeve, which is placed inside the cavity of the sampling cylinder. Then, the excavator head is screwed into the inner wall of the sampling cylinder. At this time, the excavator head can prevent the core sleeve from falling. When sampling, the sample soil will enter the core sleeve inside the sampling cylinder along the excavator head. After sampling is completed, the excavator head can be screwed out. Since the sampled soil is inside the core sleeve, the core sleeve can be quickly removed from the sampling cylinder, avoiding the soil from being wet and adhering to the inner wall of the sampling cylinder and making it difficult to remove.

[0032] To better understand the purpose, structure, and function of this utility model, the geological exploration sampling device of this utility model will be described in further detail below with reference to the accompanying drawings.

[0033] like Figure 1-5 As shown, the geological exploration sampling device of this utility model includes: a support frame, a sampling structure, and a sample core sleeve.

[0034] The support frame includes a sleeve 10 and two foot pedals 11 fixedly installed on the outer surface of the sleeve 10. The two foot pedals 11 are symmetrically arranged on the surface of the sleeve 10. A pin 12 is fixedly installed on the lower surface of the foot pedal 11. The support frame is placed in the sampling area, and the sampling personnel can fix the sleeve 10 by stepping on the foot pedals 11 with both feet. At this time, the pin 12 will be inserted into the ground to further fix the sleeve 10.

[0035] The sampling structure includes a nut seat 20 fixedly installed on the inner wall of the sleeve 10, a threaded rod 21 threadedly connected to the inner wall of the nut seat 20, and a sampler set at the lower end of the threaded rod 21. Two extended handles 50 are fixedly installed at the upper end of the threaded rod 21.

[0036] The sampler includes a sampling cylinder 30, a digging head 31 threadedly connected to the lower end of the sampling cylinder 30, and an assembly assembly disposed between the sampling cylinder 30 and the threaded rod 21. The lower end of the digging head 31 is provided with digging teeth, and the inner wall of the digging head 31 is provided with a through hole.

[0037] The assembly assembly includes a nut 40 fixedly installed at the lower end of the threaded rod 21, and an external thread on the upper end of the sampling cylinder 30. The external thread on the upper end of the sampling cylinder 30 is screwed into the nut 40, thereby assembling the sampling cylinder 30 and the threaded rod 21 into one unit.

[0038] Once the support frame is fixed in the sampling area, the sampling personnel can rotate the extended handle 50 to drive the threaded rod 21 to rotate. Utilizing the screw drive between the threaded rod 21 and the nut seat 20, the sampling cylinder 30 and the excavator head 31 can be driven to move downwards evenly according to the pitch of the threaded rod 21 while rotating, thereby allowing the sampled soil to enter the sampling cylinder 30 along the excavator head 31.

[0039] Compared with existing technologies, this device breaks away from the traditional method of inserting the sampler downwards into the soil. By using the cooperation between the threaded rod 21 and the nut seat 20, the sampler can be inserted into the soil while rotating. The digging head 31 generates tangential force when rotating, and a gap is created between the sampler and the soil after rotation, reducing friction. This makes it easier for the sampler to be inserted into the soil, making it easier for sampling personnel to use.

[0040] The sample core sleeve is located inside the sampling cylinder 30 for quick removal of the sample core. The sample core sleeve consists of two interlocking first semicircular plates 60 and second semicircular plates 61. The sampling cylinder 30 has a cavity 62 that matches the sample core sleeve. The sample core sleeve is placed into the cavity on the inner wall of the sampling cylinder 30, and then the excavation head 31 is screwed into the inner wall of the sampling cylinder 30. At this time, the excavation head 31 can prevent the sample core sleeve from falling off.

[0041] When sampling is performed, the sample soil will enter the sample core sleeve inside the sampling tube 30 along the excavation head 31. After sampling is completed, the excavation head 31 can be unscrewed. Since the sampled soil is inside the sample core sleeve, the sample core sleeve can be quickly taken out from the sampling tube 30. Then the first semicircular plate 60 and the second semicircular plate 61 can be opened to expose the sample inside, avoiding the soil from being wet and adhering to the inner wall of the sampling tube 30 and making it difficult to remove.

[0042] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
