[0025] The invention provides a geological sampling device.

[0026] 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 shell 3, a storage container 4 and a vibration component 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 transmit the peeled geological sample. The sampling shell 3 forms a sampling cavity 31 with upper and lower openings for the rotating shaft 2 to pass through. The sampling shell 3 is sleeved on the outside of the spiral blade and the drill bit, and the sampling shell 3 can protect the internal structure spiral blade and the drill bit, and can also avoid safety problems for the operator. The storage container includes a storage cavity 41, which is connected to the sampling cavity 31, and the storage cavity 41 can store the collected geological samples. The vibration component 5 is arranged on the storage container 4 to make the storage container 4 vibrate. With such a configuration, when sampling, the main motor 1 drives the shaft to rotate, driving the drill bit and the spiral blade to rotate, so that the drill bit can peel off the geological entity; and the peeled geological sample is driven by the rotation of the spiral blade and is transported to the storage cavity 41 through the sampling cavity 31. The vibration component 5 set on the storage container 4 can drive the storage container 4 to vibrate. Due to the influence of the vibration, the transported geological sample will continue to fall into the storage cavity 41, thereby reducing the possibility of the geological sample being stuck during the transportation process. Among them, the main motor 1 and the vibration component 5 are electrically connected by wires.

[0027] Furthermore, in some embodiments, the geological sampling device further includes a support spring 6, which is spirally sleeved on the outer peripheral wall of the rotating shaft 2. The support spring 6 can provide a certain elasticity and buffering effect to improve the stability of the rotating shaft 2 and the motor connected to the rotating shaft 2 during operation. In addition, the support spring 6 can also be used to reset the drill bit. In some embodiments, see Figure 3 The geological sampling device also includes a protective plate 7, which is arranged on the outer peripheral wall of the sampling shell 3; the width of the protective plate 7 is greater than the width of the sampling shell 3. The provision of the protective plate 7 plays a role in further protecting the sampling device, preventing the impact that may occur during the sampling process and the erosion of the device by the external environment. In addition, the provision of the protective plate 7 can also be used for the operator to hold it for easy movement. It can be understood that the sampling device can also be provided with a shoulder strap or the like to facilitate movement and transportation.

[0028] In some embodiments, see Figure 1 and 2 The vibration assembly 5 includes a vibration motor 51 and a fixing bracket 52, wherein 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.

[0029] In some embodiments, see Figure 1 and 4 The geological sampling device further comprises a flexible cover 8, which is arranged 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. During the sampling process, rock fragments and dust may splash onto the operator and other structures of the geological sampling device, and the setting of the flexible cover 8 is conducive to preventing this from happening.

[0030] 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 to 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 flexible materials 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.

[0031] In one embodiment, the circumferential contour size of the flexible cover 8 increases in the direction away from the sampling housing 3. Such a configuration is conducive to improving the stability of the geological sampling device. Preferably, the flexible cover 8 can be configured in a trumpet shape.

[0032] 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 through 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 with the connecting through hole; the connecting pipe 43 can make the connection between the storage container 4 and the sampling shell 3 easier, and can better adapt to the situation that 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.

[0033] Furthermore, in one embodiment, the sampling housing 3 is provided with a second through hole 33, and the position of the second through hole 33 is higher than the first through hole 32. In this way, when the storage container 4 is full, the sample can leak out from the second through hole 33; and the second through hole 33 is conducive to the sampling personnel to observe the situation inside the sampling housing 3, and can remind the sampling personnel whether the storage container 4 is full.

[0034] In one embodiment, the storage container 4 may also be provided with a seal 42, which is nested at the connection between the storage container 4 and the pipeline, that is, it further plays a sealing role to prevent the geological samples in the storage container 4 from being affected by the external environment.

[0035] 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 is conducive to the geological sample falling into the storage cavity 41 better.

[0036] In addition, in some other embodiments, the sampling housing 3 and the storage container 4 are integrally formed, and the storage container 4 further includes a sample container, which is disposed in the storage cavity 41, and the sample container and the storage container 4 are detachably disposed. That is, the stripped geological sample is transported to the sample container in the storage cavity 41 through the sampling cavity 31, and when enough geological samples are collected, the sample container can be taken out. Such a configuration is conducive to simplifying the processing and manufacturing process.

[0037] It should be further noted 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 sealing member 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 components.
