[0029] The utility model provides a geological sampling device.

[0030] See also Figure 1-4 In one embodiment of the present invention, the geological sampling device includes a main motor 1, a rotating shaft 2, a sampling housing 3, a storage container 4, and a vibration assembly 5; the first end of the rotating shaft 2 is rotatably connected to the main motor 1, and the second end of the rotating shaft 2 is provided with a spiral blade and a drill bit, and the drill bit is located at the bottom of the spiral blade; wherein the drill bit is used to crush and peel off the geological entity, and the spiral blade is used to spirally convey the peeled geological sample. The sampling housing 3 forms a sampling cavity 31 with upper and lower openings for the rotating shaft 2 to pass through. The sampling housing 3 is sleeved on the outside of the spiral blade and the drill bit. The sampling housing 3 can protect the internal structure of the spiral blade and the drill bit, and can also avoid safety problems for the operator. The storage container includes a storage chamber 41, which is connected to the sampling chamber 31 and can store the collected geological samples. The vibration assembly 5 is provided on the storage container 4 to cause the storage container 4 to vibrate. With this arrangement, during sampling, the main motor 1 drives the shaft to rotate, driving the drill bit and spiral blades to rotate, causing the drill bit to peel off the geological entity. Driven by the rotation of the spiral blades, the peeled geological sample is transported through the sampling cavity 31 to the storage cavity 41. The vibration assembly 5 provided on the storage container 4 can cause the storage container 4 to vibrate. Due to the influence of the vibration, the transported geological sample will continuously fall into the storage cavity 41, thereby reducing the possibility of the geological sample getting stuck during transportation. The main motor 1 and the vibration assembly 5 are electrically connected by wires.

[0031] Furthermore, in some embodiments, the geological sampling device further includes a support spring 6, which is helically sleeved around the outer circumference of the rotating shaft 2. The support spring 6 provides a certain degree of elasticity and cushioning to enhance the stability of the rotating shaft 2 and the motor connected thereto during operation. Furthermore, the support spring 6 can also be used to reset the drill bit.

[0032] In some embodiments, see Figure 3 The geological sampling device also includes a protective plate 7, which is mounted on the outer wall of the sampling housing 3. The width of the protective plate 7 is greater than that of the sampling housing 3. The provision of the protective plate 7 further protects the sampling device from potential impacts and environmental erosion during the sampling process. Furthermore, the provision of the protective plate 7 allows the operator to hold the device for easy movement. It is understood that the sampling device may also be provided with a shoulder strap or other means to facilitate movement and transport.

[0033] In some embodiments, see Figure 1 and 2 The vibration assembly 5 includes a vibration motor 51 and a fixing bracket 52. The fixing bracket 52 is fixed to the storage container 4. The fixing bracket 52 is used to fix the vibration motor 51. The vibration motor 51 is used to generate vibration and transmit the vibration to the storage container 4 through the fixing bracket 52, thereby driving the storage container 4 to vibrate.

[0034] In some embodiments, see Figure 1 and 4 The geological sampling device further includes a flexible cover 8 disposed at the bottom of the sampling housing 3; the lowest point of the flexible cover 8 is lower than the lowest point of the sampling housing 3. The provision of the flexible cover 8 helps prevent rock fragments and dust from splashing onto the operator and other components of the geological sampling device during the sampling process.

[0035] Furthermore, in one embodiment, the bottom of the flexible cover 8 is used to contact the sampling surface, and the bottom surface of the flexible cover 8 is provided with a tooth pattern 81. The tooth pattern 81 can increase the friction of the geological sampling device and prevent sliding during the sampling process. Specifically, the tooth pattern 81 can be arranged in certain positions on the bottom surface of the flexible cover 8 in a partitioned manner, or can be evenly arranged on the bottom surface of the flexible cover 8. The flexible cover 8 can be made of a flexible material such as rubber, which can prevent sample fragments from splashing while playing a buffering role and extending the service life of the sampling shell 3. Furthermore, in another embodiment, the flexible cover 8 is detachable for easy replacement.

[0036] In one embodiment, the circumferential profile of the flexible cover 8 increases in size in a direction away from the sampling housing 3. This configuration is beneficial for improving the stability of the geological sampling device.

[0037] In some embodiments, see Figure 1 and 2 The side wall of the sampling shell 3 is provided with a first through hole 32, and the storage container 4 is connected to the first through hole 32 via a connecting pipe 43. It can be understood that the connecting pipe 43 is a part of the storage container 4, which is used to connect to the connecting through hole; the connecting pipe 43 can make the connection between the storage container 4 and the sampling shell 3 simpler, and can better adapt to the situation where the aperture of the first through hole 32 is inconsistent with the aperture of the opening of the storage container 4. The storage container 4, the connecting pipe 43, and the sampling shell 3 can be fixedly connected in pairs or all three can be fixedly connected, or they can be detachably connected in pairs or all three can be detachably connected. When the storage container 4 is detachable, when enough geological samples are collected, the sample container can be removed; when the storage container 4 is not detachable, a detachable sample container needs to be provided in the storage container 4 to facilitate the acquisition of geological samples.

[0038] Furthermore, in one embodiment, the sampling housing 3 is provided with a second through hole 33, which is positioned higher than the first through hole 32. This arrangement allows the sample to leak out of the second through hole 33 when the storage container 4 is full. Furthermore, the second through hole 33 facilitates the sampling operator to observe the interior of the sampling housing 3 and remind the sampling operator whether the storage container 4 is full.

[0039] In one embodiment, the storage container 4 may further be provided with a seal 42, which is nested at the connection between the storage container 4 and the pipeline, that is, further playing a sealing role to prevent the geological samples in the storage container 4 from being affected by the external environment.

[0040] In some embodiments, the storage container 4 is tilted. Specifically, the opening of the storage container 4 is higher than the bottom of the storage container 4 , which helps the geological sample to fall into the storage cavity 41 better.

[0041] In some other embodiments, the sampling housing 3 and storage container 4 are integrally formed. The storage container 4 also includes a sample container, which is located within the storage cavity 41. The sample container and storage container 4 are detachable. Specifically, the exfoliated geological sample is transferred through the sampling cavity 31 to the sample container within the storage cavity 41. Once sufficient geological sample has been collected, the sample container is removed. This arrangement simplifies the processing and manufacturing process.

[0042] It should be further explained that, in some embodiments, refer to Figure 3 and 4, can include a support spring 6, a protective plate 7, a flexible cover 8, a connecting pipe 43, and a seal 42 at the same time; at this time, the protective plate 7 is located on the outside of the above-mentioned components, and the sampling container passes through the protective plate 7, so that the protective plate 7 can provide better protection for the various components.

[0043] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
