Description

Technical Field

[0001] This utility model belongs to the technical field of soil sample collection, specifically relating to an automatic positioning fault sample rotary collection device. Background Technology

[0002] To accurately analyze the geological structure of earthquake-prone areas, it is necessary to collect soil samples within fault zones periodically. Existing soil sampling devices typically employ a direct-insertion method, where a sampling rod with a cutting head is inserted directly into the soil layer to collect samples. During sampling, if the soil layer is hard or contains gravel, the cutting head may experience significant impact during insertion, leading to deformation and damage over time. Furthermore, existing soil sampling devices struggle to accurately match the sample location coordinates with the sample itself, which can easily result in mixed soil samples when a large number of samples are collected from various locations.

[0003] Therefore, in view of the above-mentioned problems of existing soil sample collection devices, this utility model discloses an automatic positioning fault sample rotary collection device. Utility Model Content

[0004] This utility model discloses an automatic positioning fault sample rotary sampling device, which can pre-break the soil layer before rotary sampling of soil samples within the fault, effectively extending the service life of the sampling part. At the same time, it can automatically locate during the sampling process and match the actual geographical coordinates of the sample.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatic positioning fault sample rotary sampling device includes a housing, a sliding cylinder slidably disposed inside the housing, a hollow sampling head disposed at the bottom end of the sliding cylinder, a rotating rod rotatably disposed inside the sliding cylinder with thread engagement, a conical rotary sampling head extending into the hollow sampling head disposed at the bottom end of the rotating rod, a spiral groove disposed on the outer conical surface of the conical rotary sampling head, a sampling cavity communicating with the spiral groove disposed between the rotating rod and the sliding cylinder, an outlet disposed on both the sampling cavity and the side wall of the housing, and a GPS locator built into the top of the housing.

[0007] When sampling is not required, the slide retracts upwards into the shell, concealing the hollow mining head and the conical rotary sampling head within the shell for protection. In this state, the shell can be used as a trekking pole. When sampling is needed, the slide is manually driven downwards, causing the hollow mining head and the conical rotary sampling head to extend downwards from the bottom of the shell. Because the conical rotary sampling head is located inside the hollow mining head, its contact with the soil occurs before the conical rotary sampling head during the downward movement of the slide. The hollow mining head breaks through the soil layer first, preventing the conical rotary sampling head from directly contacting hard structures in the soil and thus avoiding damage. Once the hollow mining head has penetrated and entered the soil layer, the rotating rod can be rotated, causing the conical rotary sampling head to rotate relative to the hollow mining head. The soil sample is then extracted upwards through the spiral grooves on the side wall of the conical rotary sampling head and transported to the collection chamber. The sample can then be retrieved through the collection chamber and the outlets on the side wall of the shell. Furthermore, during soil sampling, a GPS locator is used for real-time automatic positioning, and the collected coordinates are matched with the soil sample number to obtain the corresponding geographical location data of the soil sample.

[0008] To better realize this utility model, the side wall of the housing is provided with an axial sliding groove, and the cylinder wall of the slide is provided with a guide block that slides with the axial sliding groove, with one end of the guide block extending to the outside of the axial sliding groove.

[0009] To better realize this utility model, the outer axial sliding sleeve of the housing is further provided with a hammer, the bottom of which abuts against the top of the guide block extending to the outer part of the axial sliding groove.

[0010] To better realize this utility model, a locking pin is further provided inside the top end of the axial groove, and the locking pin abuts against the bottom of the guide block.

[0011] To better realize this utility model, the upper inner side of the slide cylinder is further provided with an inner bushing, which is circumferentially rotatably connected to the rotating rod and axially engaged.

[0012] To better realize this utility model, the bottom end of the shell is provided with an anti-slip pad, and the center of the anti-slip pad is provided with a through hole for the hollow mining head to pass through.

[0013] To better realize this utility model, the top end of the rotating rod extends upward to the outside of the housing, and a force-applying handle is provided at the top end of the rotating rod.

[0014] To better realize this utility model, a mounting cavity is further provided on one side of the top of the housing, and a battery pack and a GPS locator are provided inside the mounting cavity, with the battery pack and the GPS locator connected.

[0015] To better realize this utility model, the bottom end of the hollow mining head is further provided with an arc-shaped slit.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0017] (1) This utility model slides a sliding cylinder inside the shell and rotates a rotating rod inside the sliding cylinder with a threaded fit. By sliding the sliding cylinder downward, the hollow mining head at the bottom of the sliding cylinder breaks the soil layer in advance. Then, the rotating rod is rotated so that the conical rotary mining head at the bottom of the rotating rod can perform rotary mining on the broken soil layer. This replaces the traditional direct insertion mining method, thereby avoiding direct impact between the conical rotary mining head and the soil layer, avoiding damage to the conical rotary mining head and extending the service life of the conical rotary mining head.

[0018] (2) When no sample collection is required, the present invention can slide the slide cylinder upward to hide the conical rotary head and the hollow excavation head inside the shell, thereby avoiding direct contact between the conical rotary head and the hollow excavation head and the soil layer. At this time, the shell can be used as a hiking pole and can effectively protect the conical rotary head and the hollow excavation head.

[0019] (3) This utility model has a GPS locator installed on the shell, which enables real-time navigation and allows for accurate acquisition of the geographical coordinates of the collected samples in real time during sample collection. Attached Figure Description

[0026] Example 1:

[0027] This embodiment provides an automatic positioning fault sample extraction device, such as... Figures 1-5 As shown, the device includes a housing 1, inside which a sliding cylinder 2 is slidably disposed. A hollow mining head 3 is disposed at the bottom end of the sliding cylinder 2. A rotating rod 4 is rotatably disposed inside the sliding cylinder 2 with a threaded fit. A conical rotary mining head 5 extending into the hollow mining head 3 is disposed at the bottom end of the rotating rod 4. A spiral groove is disposed on the outer conical surface of the conical rotary mining head 5. A collection cavity 6 communicating with the spiral groove is disposed between the rotating rod 4 and the sliding cylinder 2. An outlet is disposed on both the collection cavity 6 and the side wall of the housing 1. A GPS locator is built into the top of the housing 1.

[0028] The hollow excavator head 3 is made of cemented carbide, ensuring sufficient rigidity and strength. The slide cylinder 2 can drive the hollow excavator head 3, the rotating rod 4, and the conical rotary excavator head 5 to move axially relative to the housing 1. When sample extraction is not required, the slide cylinder 2 moves upward to hide the hollow excavator head 3 and the conical rotary excavator head 5 inside the housing 1, thus protecting them. At the same time, the housing 1 can be used as a hiking pole.

[0029] When a sample needs to be collected, the slide 2 moves downward to drive the hollow excavator head 3 and the conical rotary excavator head 5 to extend downward from the shell 1. Since the conical rotary excavator head 5 is located inside the hollow excavator head 3, the hollow excavator head 3 will contact the soil layer before the conical rotary excavator head 5. The hollow excavator head 3 breaks up the soil layer in advance, breaking up relatively hard soil layers and gravel layers, thereby reducing the force on the conical rotary excavator head 5 and extending its service life. After the hollow excavator head 3 breaks up and inserts into the soil layer, the soil sample enters the hollow excavator head 3. At this time, the rotating rod 4 can be rotated to drive the conical rotary excavator head 5 to rotate, and then the soil sample inside the hollow excavator head 3 is transported upward through the spiral groove on the side wall of the conical rotary excavator head 5 to the collection chamber 6 for sample collection. The collected samples can be retrieved through the collection chamber 6 and the outlet on the shell 1. Throughout the sampling process, the samples will not come into direct contact with the external environment, thus avoiding the influence of light and moisture from the external environment on the samples. For example, during the collection of optically stimulated luminescence (OSL) samples, the samples can be prevented from coming into contact with external light.

[0030] Furthermore, during the sample collection process, the GPS locator is used for automatic positioning, and then the geographical coordinates are matched with the collected samples to determine the specific coordinates of the sample collection location.

[0031] Example 2:

[0032] This embodiment discloses an automatically positioned fault sample extraction device, which is an optimization based on Embodiment 1, such as... Figure 1 and Figure 2As shown, an axial groove 100 is provided on the side wall of the housing 1, and a guide block 200 is provided on the cylinder wall of the slide cylinder 2 to slide in cooperation with the axial groove 100. One end of the guide block 200 extends to the outside of the axial groove 100.

[0033] Axial grooves 100 are symmetrically arranged on the side walls of the left and right sides of the housing 1. Guide blocks 200 extending into the axial grooves 100 and slidably connected to the axial grooves 100 are respectively arranged on the cylinder walls of the left and right sides of the slide cylinder 2. One end of the guide block 200 extends to the outside of the axial groove 100 so that the guide block 200 can be manually held to apply axial external force, thereby conveniently driving the slide cylinder 2 to slide axially.

[0034] Furthermore, an impact hammer 300 is axially slidably fitted onto the outer side of the housing 1. The bottom of the impact hammer 300 abuts against the top of the portion of the guide block 200 extending to the outer side of the axial groove 100. For harder ground, it is difficult to break through the soil layer by simply holding the guide block 200 and sliding it downwards. In this case, the impact hammer 300 can strike the top of the guide block 200 downwards, thereby applying additional axial impact force to the slide cylinder 2, so that the hollow mining head 3 can successfully break through the soil layer.

[0035] Furthermore, a locking pin 400 is inserted inside the top of the axial groove 100, and the locking pin 400 abuts against the bottom of the guide block 200. When sample extraction is not required, to prevent the slide cylinder 2 from sliding down under its own weight, the locking pin 400 is inserted into the pin hole on the side wall of the axial groove 100. The locking pin 400 abuts against the bottom of the guide block 200, preventing the guide block 200 from sliding down on its own. When sample extraction is required, the locking pin 400 is removed, and the guide block 200 can then slide smoothly along the axial groove 100.

[0036] The rest of this embodiment is the same as that of Embodiment 1, so it will not be described again.

[0037] Example 3:

[0038] This embodiment discloses an automatically positioned fault sample extraction device, which is an optimization based on Embodiment 1 or 2, such as... Figure 4 and Figure 5 As shown, an inner liner 8 is provided on the upper side of the inner side of the slide cylinder 2. The inner liner 8 is circumferentially rotatably connected to the rotating rod 4 and axially engaged.

[0039] The inner wall of the inner bushing 8 is provided with an annular groove, and the outer wall of the rotating rod 4 is provided with a flange that is rotatably connected to the annular groove. At the same time, the flange is axially engaged with the annular groove, so that the rotating rod 4 can rotate circumferentially but cannot slide axially.

[0040] The rest of this embodiment is the same as that of embodiment 1 or 2, so it will not be described again.

[0041] Example 4:

[0042] This embodiment discloses an automatically positioned fault sample extraction device, which is optimized based on any one of embodiments 1-3, such as... Figure 4 and Figure 5 As shown, the bottom of the housing 1 is provided with an anti-slip pad 7, and the center of the anti-slip pad 7 has a through hole for the hollow mining head 3 to pass through. When the hollow mining head 3 and the conical rotary mining head 5 are hidden inside the housing 1, the anti-slip pad 7 is in contact with the ground, working with the housing 1 to function as a trekking pole. When it is necessary to excavate a sample, the hollow mining head 3 and the conical rotary mining head 5 extend downwards from the through hole of the anti-slip pad 7 and contact the soil layer, and sample excavation can begin.

[0043] The rest of the content of this embodiment is the same as any one of embodiments 1-3, so it will not be repeated here.

[0044] Example 5:

[0045] This embodiment discloses an automatically positioned fault sample extraction device, which is optimized based on any one of embodiments 1-4, such as... Figure 1 As shown, the top of the rotating rod 4 extends upward to the outside of the housing 1, and a force-applying handle is provided at the top of the rotating rod 4. By holding the force-applying handle, the rotating rod 4 can be rotated more conveniently and effortlessly. To prevent slippage, an anti-slip rubber sleeve is wrapped around the outside of the force-applying handle.

[0046] Furthermore, a mounting cavity is provided on one side of the top of the housing 1. A battery pack and a GPS locator are installed inside the mounting cavity. The battery pack and the GPS locator are connected. The GPS locator is used to provide real-time geographic location coordinates, which can not only realize navigation, but also match real-time coordinate information when collecting samples, so as to correspond the collected samples with the actual geographic location coordinates.

[0047] Furthermore, the bottom end of the hollow mining head 3 is provided with an arc-shaped slit. By providing the arc-shaped slit, the stress on the hollow mining head 3 when it impacts the soil layer can be improved, effectively preventing the hollow mining head 3 from being directly deformed.

[0048] The rest of the content of this embodiment is the same as any one of embodiments 1-4, so it will not be repeated here.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
