Description

Technical Field

[0001] This utility model belongs to the field of soil sampling technology, specifically relating to a sampling device for soil pollution remediation. Background Technology

[0002] Soil sampling equipment is a type of device used to sample soil. It mainly tests and evaluates soil quality by sampling at different depths. Common soil sampling equipment in the current technology includes fully automatic sampling equipment, semi-automatic sampling equipment, and manual sampling equipment. Among them, fully automatic sampling equipment can sample soil automatically, but it has problems such as high operating cost, cumbersome and complex structure, and large applicability. Semi-automatic sampling equipment mainly uses diesel or gasoline engines to drive the sampling cylinder to rotate and sample the soil by drilling through the sampling cylinder. This type of sampling equipment has the problems of large structural weight and poor portability. Although manual sampling equipment is easy to carry, the accuracy and reliability of vertical soil sampling are poor.

[0003] Because soil pollution remediation requires frequent and accurate sampling at multiple locations, neither fully automatic, semi-automatic, nor manual sampling equipment can meet the sampling requirements of the soil pollution remediation process.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a sampling device for soil pollution remediation.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a sampling device for soil pollution remediation, which can improve the convenience and reliability of soil sampling in soil pollution remediation areas.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides a sampling device for soil pollution remediation, comprising: a drilling guide block, a support and positioning component, and a split drilling component.

[0008] The support and positioning assembly is fixedly assembled on the outside of the drilling guide block. The support and positioning assembly includes multiple fixed supports, which are evenly assembled on the outside of the drilling guide block. Each of the multiple fixed supports has a telescopic inner rod hinged inside. A retractable outer rod is slidably assembled on the side of the telescopic inner rod away from the fixed support.

[0013] In one or more embodiments of this utility model, a locking bolt is threaded onto the outer side of the retractable outer rod, and one end of the locking bolt located inside the retractable outer rod contacts the outer surface of the telescopic inner rod. The telescopic inner rod is locked and limited by the mutual contact between the locking bolt and the retractable outer rod, ensuring the stability of the telescopic inner rod and the retractable outer rod in supporting and limiting the drilling guide block.

[0014] In one or more embodiments of this utility model, the upper surface of the positioning pedal is provided with anti-slip protrusions. The anti-slip protrusions ensure the stability of the positioning pedal during use. A positioning cone is fixedly connected to the lower surface of the positioning pedal. The positioning cone assists in positioning the positioning pedal.

[0015] In one or more embodiments of this utility model, a drive handwheel is fixedly connected to the upper end of the threaded rod. The threaded rod is rotated by controlling the rotation of the drive handwheel. A fixing sleeve is integrally formed on the side of the sampling cylinder close to the threaded rod. The threaded rod and the sampling cylinder are connected and limited by inserting and fixing the fixing sleeve.

[0016] In one or more embodiments of this utility model, both the lower end of the threaded rod and the fixed sleeve are provided with insertion positioning holes, and positioning pins are inserted into the insertion positioning holes.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] like Figures 1 to 5 As shown, a sampling device for soil pollution remediation in one embodiment of the present invention includes: a drilling guide block 1, a support and positioning component 2, and a split drilling component 3.

[0029] Specifically, a threaded hole is provided in the drilling guide block 1. The threaded hole facilitates the movement and limiting of the threaded rod 301, allowing the threaded rod 301 to rotate and move as it rotates, thanks to the engagement of the internal and external threads.

[0030] like Figures 1 to 2 As shown, the drill guide block 1 has multiple weight-reducing through holes, which are evenly distributed on the outside of the threaded hole. By opening the weight-reducing through holes, the material used for machining the drill guide block 1 can be reduced, the weight of the drill guide block 1 can be reduced, and the portability of the drill guide block 1 can be improved.

[0031] like Figures 1 to 2 As shown, a marker support rod 4 is fixedly connected to one side of the drilling guide block 1, and a handle 5 is fixedly connected to the upper end of the marker support rod 4. The cooperation between the marker support rod 4 and the handle 5 allows the user to provide auxiliary support to the drilling guide block 1 when rotating the drive handwheel 304, thereby improving the stability of the drilling guide block 1.

[0032] Specifically, a scale value is provided on one side of the indicator support rod 4. The range of the scale value is the same as the stroke of the threaded rod 301, and the scale value gradually increases from bottom to top. By observing the change in the position of the scale value and the drive handwheel 304, the movement distance of the threaded rod 301 is judged, thereby judging the sampling depth of the drill bit 303.

[0033] like Figures 1 to 2 As shown, the support and positioning assembly 2 is fixedly assembled on the outside of the drilling guide block 1. The support and positioning assembly 2 includes multiple fixed supports 201, which are evenly assembled on the outside of the drilling guide block 1. The fixed supports 201 serve to connect the telescopic inner rod 202 and the drilling guide block 1.

[0034] like Figures 1 to 2 As shown, each of the multiple fixed supports 201 has a telescopic inner rod 202 hinged within it, and a retractable outer rod 203 is slidably fitted onto the side of the telescopic inner rod 202 facing away from the fixed support 201. Through the telescopic cooperation of the telescopic inner rod 202 and the retractable outer rod 203, the drilling guide block 1 can be supported and limited at different heights and angles.

[0035] like Figure 4 As shown, a locking bolt 205 is threaded onto the outer side of the retractable outer rod 203. One end of the locking bolt 205, located inside the retractable outer rod 203, contacts the outer surface of the telescopic inner rod 202. The telescopic inner rod 202 is locked and limited by the mutual contact between the locking bolt 205 and the retractable outer rod 203, ensuring the stability of the telescopic inner rod 202 and the retractable outer rod 203 in supporting and limiting the drilling guide block 1.

[0036] like Figures 4 to 5 As shown, a positioning pedal 204 is hinged to the lower end of the retractable outer rod 203. The positioning pedal 204 supports and positions the retractable outer rod 203.

[0037] like Figures 2 to 5 As shown, the upper surface of the positioning pedal 204 is provided with anti-slip protrusions 206. The anti-slip protrusions 206 ensure the stability of the positioning pedal 204 during use. A positioning cone 207 is fixedly connected to the lower surface of the positioning pedal 204. The positioning cone 207 provides auxiliary positioning for the positioning pedal 204.

[0038] like Figures 1 to 2 As shown, the split-type drilling assembly 3 is assembled inside the drilling guide block 1. The split-type drilling assembly 3 includes a threaded rod 301, which passes through the drilling guide block 1 and is threadedly connected to the drilling guide block 1. By controlling the rotation of the threaded rod 301, the threaded rod 301 can drive the sampling cylinder 302 to rotate and move under the action of the internal and external threads, thereby realizing soil drilling.

[0039] like Figures 1 to 2 As shown, a sampling cylinder 302 is inserted into the lower end of the threaded rod 301. Soil samples are taken through the sampling cylinder 302. A drill bit 303 is threadedly connected to the lower end of the sampling cylinder 302. The rotation of the drill bit 303 improves the smoothness of drilling and sampling through the sampling cylinder 302.

[0040] In addition, in practical applications, soil sampling can be carried out by matching a single drill bit 303 with multiple sampling tubes 302. After long-term use, the drill bit 303 with greater wear can be replaced independently, which reduces the use and maintenance cost of the sampling equipment.

[0041] like Figures 2 to 3 As shown, the lower end of the sampling cylinder 302 has an external thread, and the upper end of the drill bit 303 has an internal thread that matches the sampling cylinder 302. The interaction of the internal and external threads allows for easy assembly and disassembly of the sampling cylinder 302 and the drill bit 303. The lower end of the drill bit 303 is serrated, improving the smoothness of rotary excavation of the drill bit 303.

[0042] like Figures 1 to 2 As shown, a drive handwheel 304 is fixedly connected to the upper end of the threaded rod 301. The threaded rod 301 is rotated by controlling the rotation of the drive handwheel 304.

[0043] like Figures 2 to 3 As shown, a fixing sleeve 305 is integrally formed on the side of the sampling cylinder 302 close to the threaded rod 301. The threaded rod 301 and the sampling cylinder 302 are connected and limited by inserting and fixing the fixing sleeve 305.

[0044] like Figures 2 to 3 As shown, both the lower end of the threaded rod 301 and the fixed sleeve 305 have insertion positioning holes, and positioning pins 306 are inserted into the insertion positioning holes. The fixed sleeve 305 and the threaded rod 301 are connected and limited by inserting positioning pins 306 into the insertion positioning holes.

[0045] In practical use, the locking bolt 205 is rotated according to the actual sampling requirements. By controlling the rotation of the locking bolt 205, the locking state of the telescopic inner rod 202 is released. Subsequently, the length of the telescopic inner rod 202 and the retractable outer rod 203 can be adjusted by pulling the telescopic inner rod 202, so as to support and position the drilling guide block 1 at different angles and heights.

[0046] The drilling guide block 1 is supported and positioned by the cooperation of the telescopic inner rod 202, the retractable outer rod 203 and the positioning pedal 204. Furthermore, the threaded rod 301 and the sampling cylinder 302 can be connected by inserting the positioning pin 306. The sampling cylinder 302 and the drilling head 303 are combined by the threaded engagement between the sampling cylinder 302 and the drilling head 303.

[0047] In use, the drill bit 303 can be moved and lowered by controlling the rotation of the drive handwheel 304. When the drill bit 303 contacts the soil surface, the value of the marked scale on the surface of the indicator support rod 4 is observed. Subsequently, the sampling cylinder 302 can be drilled and sampled from the soil by continuing to control the rotation of the drive handwheel 304. The depth of the sampling can be determined by observing the marked scale value. After sampling is completed, the sampling cylinder 302 can be lifted and reset by rotating the drive handwheel 304 in the opposite direction. After reset, the sampling cylinder 302 can be easily disassembled by removing the positioning pin 306, thus completing the sampling process.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
