Description

Technical Field

[0001] This utility model belongs to the field of soil sampling technology, and in particular relates to a soil sampling device for land remediation. Background Technology

[0002] Soil sampling devices are used to sample soil. Soil sampling refers to the methods of collecting soil samples, including sampling layout and sampling techniques. Profile soil samples should be collected after the profile observation and recording are completed.

[0003] Before sampling, the entire profile should be repaired and cleaned, and the top layer of loose soil should be removed. Then, samples should be taken from the central typical part layer by layer from top to bottom. Usually, shovels are used for digging during the collection process, which makes it difficult to control the digging depth. This method is too limited, time-consuming and labor-intensive, and also makes it difficult to ensure the uniformity of the soil samples. Therefore, we provide a soil sampling device for land remediation. Utility Model Content

[0004] The purpose of this invention is to provide a soil sampling device for land remediation. By adjusting the limit of the threaded rod, the device can sample the soil at the limit depth, which solves the problems of existing sampling equipment being time-consuming and labor-intensive, and making it difficult to ensure the uniformity of soil samples.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a soil sampling device for land remediation, including a fixed frame, an adjustment and limiting mechanism inside the fixed frame, and a collection mechanism on the right side of the fixed frame;

[0007] The adjusting and limiting mechanism includes a threaded rod, the outer surface of which is rotatably connected to the inner wall of a first fixed frame. A connecting plate is threaded onto the outer surface of the threaded rod. A limiting rod is slidably connected to the inner wall of the connecting plate away from the first fixed frame. A second fixed frame is fixedly connected to the outer wall of the limiting rod. A sliding groove is provided inside the first fixed frame. A limiting block is slidably connected to the inner wall of the sliding groove. An insert rod is slidably connected to the inner wall of the limiting block. A limiting disc is fixedly connected to the outer surface of the insert rod. A telescopic spring is fixedly connected to the outer wall of the limiting disc. A distance measuring plate is fixedly connected to the outer wall of the first fixed frame. An insertion hole is provided inside the distance measuring plate.

[0008] Furthermore, the inner wall of the limiting block contacts the outer surface of the threaded rod, the end of the outer wall of the telescopic spring away from the limiting disc is fixedly connected to the inner wall of the limiting block, the outer surface of the insertion rod extends through the outer wall of the limiting block to the outside, and the inner wall of the insertion hole is slidably connected to the outer surface of the insertion rod.

[0009] Furthermore, the acquisition mechanism includes a motor, the bottom of which is fixedly connected to the top of the connecting plate.

[0010] Furthermore, a rotating rod is fixedly connected to the bottom output shaft of the motor via a coupling, a helical blade is fixedly connected to the outer surface of the rotating rod, and a drill bit is fixedly connected to the bottom of the rotating rod.

[0011] Furthermore, a sliding block is fixedly connected to the bottom of the connecting plate, the top of the sliding block is fixedly connected to the bottom of the connecting plate, a second splicing box is slidably connected to the outer surface of the sliding block, and a baffle is fixedly connected to the inner wall of the second splicing box. There are two baffles in total.

[0012] Furthermore, the splicing box two has a slot two inside, a fixed shaft is fixedly connected to the outer wall of the splicing box two, and a locking block is rotatably connected to the outer surface of the fixed shaft.

[0013] Furthermore, the end of the outer surface of the sliding block away from the splicing box two is slidably connected to the splicing box one, and the outer wall of the splicing box one is fixedly connected to the insert plate, the outer surface of the insert plate being adapted to the inner wall of the slot two.

[0014] Furthermore, a fixing block is fixedly connected to the outer wall of the splicing box, and a slot is provided inside the fixing block. The inner wall of the slot is slidably connected to the outer surface of the block.

[0015] This utility model has the following beneficial effects:

[0016] This invention utilizes a sampling rod. When soil sampling is required, the position of the limiting block is first adjusted, and then the sampling rod is pulled. The rod then drives the limiting plate to compress the telescopic spring, causing the rod to disengage from the measuring plate. The desired sampling depth is then selected based on the measuring plate. After selection, the limiting block can be manually slid. Once the appropriate insertion hole is reached, the rod can be released, allowing it to be inserted into the hole. The motor can then be started to rotate the drill bit and spiral blades. Tightening the threaded rod causes the connecting plate and drill bit to move downwards, while the connecting plate slides on the surface of the limiting rod. As the drill bit penetrates deeper into the soil, the designated position is reached when the connecting plate contacts the limiting block and cannot be tightened further. This allows for precise adjustment of the sampling depth, simplifies the sampling process, and effectively improves sampling efficiency and accuracy. It is suitable for precise sampling of different soil layers.

[0017] This invention utilizes spiral blades. Upon reaching the designated position, the motor can be turned off, and then splicing boxes one and two can be simultaneously slid into the surfaces of the sliding blocks on both sides. The insert plate will then be inserted into the slot two inside splicing box two. The locking block can then be rotated to lock it into slot one, thus securing it. The motor can then be restarted, and the rotating rod will drive the spiral blades on the surface and the drill bit at the bottom to rotate. The spiral blades will then carry the soil from the bottom into splicing boxes one and two, thus completing the collection. When it is necessary to disassemble splicing boxes one and two, the locking block can be removed from slot one, and then splicing boxes one and two can be pulled separately. The insert plate will then disengage from slot two, achieving quick disassembly and installation. This also ensures a stable connection, preventing loosening or leakage during operation, improving the overall efficiency and durability of the equipment, and reducing maintenance costs.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The adjusting limit mechanism 1 includes a threaded rod 104. Rotating the threaded rod 104 can drive the connecting plate 103 to move up and down, thereby pushing the drill bit 207 into the ground to excavate the soil, thus significantly reducing the consumption of manpower. The outer surface of the threaded rod 104 is rotatably connected to the inner wall of the fixed frame 101. The connecting plate 103 is threadedly connected to the outer surface of the threaded rod 104. A limit rod 112 is slidably connected to the end of the inner wall of the connecting plate 103 away from the fixed frame 101. The limit rod 112 can control the connection. The plate 103 is limited, thus allowing it to move horizontally in a straight line. A fixing frame 102 is fixedly connected to the outer wall of the limiting rod 112. A sliding groove 105 is opened inside the fixing frame 101. A limiting block 106 is slidably connected to the inner wall of the sliding groove 105. By sliding the limiting block 106 inside the sliding groove 105, the connecting plate 103 can be limited, thereby greatly improving the accuracy of the drilling depth of the drill bit 207. An insert rod 109 is slidably connected to the inner wall of the limiting block 106. The insert rod 109 can be used to limit the movement of the connecting plate 103. The positioning block 106 is fixed to facilitate adjustment of the required digging depth of the drill bit 207. A limiting plate 110 is fixedly connected to the outer surface of the insertion rod 109. A telescopic spring 111 is fixedly connected to the outer wall of the limiting plate 110. The telescopic spring 111 applies pressure to the limiting plate 110, causing the insertion rod 109 to be tightly inserted into the measuring plate 107, thereby fixing the limiting block 106. The measuring plate 107 is fixedly connected to the outer wall of the fixing frame 101, allowing workers to easily adjust the limiting block 106. Position 6, thereby achieving precise excavation of the soil. The measuring plate 107 has an insertion hole 108 inside.

The end of the outer wall of the telescopic spring 111 away from the limiting plate 110 is fixedly connected to the inner wall of the limiting block 106. The outer surface of the insertion rod 109 extends to the outside through the outer wall of the limiting block 106. The inner wall of the insertion hole 108 is slidably connected to the outer surface of the insertion rod 109. The collection mechanism 2 includes a motor 201. The bottom of the motor 201 is fixedly connected to the top of the connecting plate 103.

[0031] The bottom output shaft of motor 201 is fixedly connected to a rotating rod 204 via a coupling. A spiral blade 208 is fixedly connected to the outer surface of the rotating rod 204. The spiral blade 208 can transport the soil excavated by drill bit 207 upwards. The bottom of the rotating rod 204 is fixedly connected to the drill bit 207, which can drill holes and excavate the soil. A sliding block 209 is fixedly connected to the bottom of connecting plate 103. The top of the sliding block 209 is fixedly connected to the bottom of connecting plate 103. The sliding block 209 can limit the positioning of splicing box one 202 and splicing box two 203, ensuring they precisely wrap around the spiral blade 208. The two splicing boxes 203 and 202 are positioned at the same level. The outer surface of the sliding block 209 is slidably connected to the splicing box 203. The inner wall of the splicing box 203 is fixedly connected to the baffle 213. The baffle 213 can limit the soil inside the splicing box 202 and the splicing box 203 to prevent it from spilling out when the splicing box 202 and the splicing box 203 are disassembled. There are two baffles 213. The splicing box 203 has a slot 214 inside. The outer wall of the splicing box 203 is fixedly connected to the fixed shaft 205. The outer surface of the fixed shaft 205 is rotatably connected to the locking block 212.

[0032] A first splicing box 202 is slidably connected to the end of the outer surface of the sliding block 209 away from the splicing box 203. An insert plate 211 is fixedly connected to the outer wall of the first splicing box 202. By first inserting the first splicing box 202 and the second splicing box 203 on both sides into the sliding blocks 209 on both sides, the insert plate 211 on the outer wall of the first splicing box 202 will be inserted into the slot 214 of the second splicing box 203. Then, the locking block 212 is rotated so that the locking block 212 is locked in the slot 210 inside the fixed block 206, thereby splicing them together. This enables them to be quickly installed and disassembled, greatly improving the acquisition rate. The outer surface of the insert plate 211 is adapted to the inner wall of the slot 214. A fixed block 206 is fixedly connected to the outer wall of the first splicing box 202. The slot 210 is opened inside the fixed block 206, and the inner wall of the slot 210 is slidably connected to the outer surface of the locking block 212.

[0033] One specific application of this embodiment is:

[0034] When soil sampling is required, first adjust the position of the limiting block 106, then pull the insertion rod 109. The insertion rod 109 will then drive the limiting plate 110 to compress the telescopic spring 111, causing the insertion rod 109 to disengage from the measuring plate 107. Then, select the desired sampling depth according to the measuring plate 107. After selection, manually slide the limiting block 106. The limiting block 106 will slide within the sliding groove 105. When it slides to the appropriate insertion hole 108, release the insertion rod 109. The insertion rod 109 will then be reset by the telescopic spring 111, allowing the insertion rod 109 to be inserted into the insertion hole. The drill bit 207 and the spiral blade 208 are fixed inside the hole 108. Then, the motor 201 can be started to drive the drill bit 207 and the spiral blade 208 to rotate. At this time, the threaded rod 104 is turned, and the threaded rod 104 will drive the connecting plate 103 and the drill bit 207 to move downward. At the same time, the connecting plate 103 will slide on the surface of the limiting rod 112. As the drill bit 207 penetrates deeper into the soil, when the connecting plate 103 contacts the limiting block 106 and cannot be turned, the designated position can be reached, thereby accurately adjusting the sampling depth, simplifying the sampling process, effectively improving the sampling efficiency and accuracy, and is suitable for accurate sampling of different soil layers.

[0035] Upon reaching the designated position, motor 201 can be turned off. Then, splicing box one 202 and splicing box two 203 can be simultaneously slid into the surfaces of the sliding blocks 209 on both sides. The insert plate 211 will then insert into the slot two 214 inside splicing box two 203. At this point, the locking block 212 can be rotated to engage it in slot one 210, thus completing the fixation. Motor 201 can then be restarted, driving the rotating rod 204 to rotate. The rotating rod 204 will then drive the spiral blades 208 on the surface and the drill bit 207 at the bottom to rotate. The spiral blades 208 will then move the soil from the bottom and feed it into splicing box one 202 and splicing box two 203. Internally, the collection is completed. When it is necessary to disassemble splicing box 1 202 and splicing box 203, the card block 212 can be removed from the card slot 1 210. Then, splicing box 1 202 and splicing box 203 are pulled respectively. Then, the insert plate 211 will come out from the card slot 214. At the same time, the baffle 213 will prevent a large amount of soil from being lost from the inside of splicing box 1 202 and splicing box 203, thus completing the disassembly and sampling. This achieves quick disassembly and installation, and also ensures a stable connection, preventing loosening or leakage during operation. The splicing box can be replaced or cleaned quickly and safely, improving the overall efficiency and durability of the equipment and reducing maintenance costs.
