Description

Technical Field

[0001] This utility model relates to a sampling device, and more particularly to a device that can assist workers in taking samples and cores from the ground, belonging to the technical field of soil sampling equipment. Background Technology

[0002] Soil sampling is a common detection method. Currently, soil sampling is done using a soil sampler, which is cylindrical in shape. Workers hold the sampler and insert it vertically into the soil, then pull it out, bringing the soil sample with it. However, in actual operations, some soil types are quite hard, making it impossible to insert the sampler directly to the designated depth, which increases the workload of workers and reduces sampling efficiency. Therefore, there is a need for a device that can assist workers in efficiently sampling soils with different geological conditions, thereby reducing labor intensity and improving sampling efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a soil sampling device that can not only reduce the labor intensity of workers, but also improve the efficiency of soil core sampling.

[0004] The problem described in this utility model is solved by the following technical solution: A soil sampling device includes a straight cylinder, a sampling mechanism, a top cover, a sampling section, and an annular locking member; multiple pedals are symmetrically arranged circumferentially at the bottom end of the outer wall of the straight cylinder; the top cover is located on the top surface of the straight cylinder; the sampling mechanism is located in the center of the top cover; the sampling section is located on the edge of the top cover; and the annular locking member is located at the top of the sampling section.

[0005] The above-mentioned soil sampling device includes a sampling section comprising multiple sampling components, which are evenly arranged along the circumference of the top cover at the edge of the top cover. Each sampling component includes a guide post and a long shovel. Multiple guide holes are arranged circumferentially at the edge of the top cover, and a guide post is inserted into each guide hole. The bottom end of the guide post is connected to the top end of the long shovel, which is located inside a straight cylinder. The end face of the long shovel near the inner wall of the straight cylinder is an arc-shaped surface, and the arc-shaped surface of the long shovel near the inner wall of the straight cylinder is pressed against the inner wall of the straight cylinder. The side walls of adjacent long shovels are in contact with each other.

[0006] The above-mentioned soil sampling device includes two semi-circular plates; the inner wall of the semi-circular plates is provided with an arc-shaped groove; the top of the guide column is provided with a locking block; the two semi-circular plates are brought close together and merged into a complete circle, and all the locking blocks are locked in the arc-shaped grooves on the inner wall of the semi-circular plates.

[0007] The above-mentioned soil sampling device includes a sampling mechanism comprising a long rod and a circular push plate; a perforation is provided in the center of the top cover, and the long rod passes through the central hole of the top cover; the center of the top surface of the circular push plate is located on the bottom surface of the long rod; the circular push plate is located directly below the top cover; a magnet is embedded in the top of the circular push plate, and a magnet is embedded in the bottom surface of the top cover, and the magnet at the top of the circular push plate and the magnet at the bottom of the top cover attract each other.

[0008] This invention utilizes the cooperation of a sampling section and a ring-shaped locking component to drive the long shovel plate below the sampling section into the ground, and then pull the long shovel plate out to complete the soil sampling. Finally, the sample is pushed out of the cylinder formed by the long shovel plate by the sampling mechanism. If the soil is hard, the ring-shaped locking component can be removed, and the top of each guide post can be tapped individually to drive each long shovel plate into the ground. By concentrating the force, the long shovel plate is successfully inserted into the ground. Attached Figure Description

[0010] The list of labels in the diagram is as follows: 1. Straight cylinder, 2. Top cover, 3. Pedal, 4. Guide post, 5. Long shovel plate, 6. Semi-circular plate, 7. Locking block, 8. Long rod, 9. Round push plate. Detailed Implementation

[0011] See Figure 1 , 2 and Figure 3 This utility model includes a straight cylinder 1, a sampling mechanism, a top cover 2, a sampling section, and an annular locking member. Multiple pedals 3 are symmetrically arranged circumferentially at the bottom of the outer wall of the straight cylinder 1. When a worker steps on the pedals 3, the straight cylinder 1 is relatively fixed to the ground, facilitating subsequent soil sampling. The top cover 2 is located on the top surface of the straight cylinder 1. The sampling mechanism is positioned centrally on the top cover 2. The sampling mechanism can push the soil sample taken by the sampling section out from the surrounding long shovel, making it easier for the worker to remove it. The sampling section is located along the edge of the top cover 2. The annular locking member is located at the top of the sampling section. The annular locking member can smoothly raise and lower the sampling section, thereby driving the long shovel in the sampling section to penetrate deep into the soil. When the sampling section is pulled out, the soil sample is also brought out with it.

[0012] The sampling section includes multiple sampling components, which are evenly arranged along the circumference of the top cover 2 at the edge of the top cover 2. Each sampling component includes a guide post 4 and a long shovel 5. The guide post 4 drives the long shovel 5 to rise and fall synchronously, ensuring its reliable rise and fall. Multiple guide holes are arranged circumferentially at the edge of the top cover 2, and a guide post 4 is inserted into each guide hole. The bottom end of the guide post 4 is connected to the top end of the long shovel 5, which is located inside the straight cylinder 1. The end face of the long shovel 5 near the inner wall of the straight cylinder 1 is an arc-shaped surface, and the arc-shaped surface of the long shovel 5 near the inner wall of the straight cylinder 1 is pressed against the inner wall of the straight cylinder 1. The side walls of adjacent long shovel 5 are in contact with each other. Multiple long shovel 5 press against each other to form a cylindrical shape, which is open at both ends. When it is inserted into the soil, the soil sample is collected in the cylinder formed by the long shovel 5. When the long shovel 5 assembly is pulled out, the soil sample is pulled out with it.

[0013] The annular snap-fit ​​component includes two semi-circular plates 6; the inner wall of the semi-circular plates 6 is provided with an arc-shaped slot; the top of the guide post 4 is provided with a snap-fit ​​block 7; the two semi-circular plates 6 approach each other and merge into a complete circle, and all the snap-fit ​​blocks 7 are snapped into the arc-shaped slots on the inner wall of the semi-circular plates 6; the two semi-circular plates 6 can be merged and clamp all the snap-fit ​​blocks 7. By applying force to the merged semi-circular plates 6, the force is transmitted to the snap-fit ​​blocks 7, and then sequentially transmitted to the guide post 4 and the long shovel plate 5. After being subjected to force, the long shovel plate 5 moves downward and shovels into the soil.

[0014] The sampling mechanism includes a long rod 8 and a circular push plate 9; the top cover 2 has a through hole in its center, and the long rod 8 passes through the central hole of the top cover 2; the center of the top surface of the circular push plate 9 is located on the bottom surface of the long rod 8; the circular push plate 9 is located directly below the top cover 2; a magnet is embedded in the top of the circular push plate 9, and a magnet is embedded in the bottom surface of the top cover 2, and the magnet at the top of the circular push plate 9 and the magnet at the bottom of the top cover 2 attract each other; pushing the long rod 8 will drive the circular push plate 9 to move synchronously, pushing the circular push plate 9 to push the soil surrounded by the long shovel out of the long shovel, making it easier for staff to take away the soil sample.

[0015] Operating principle: Move this device above the soil to be sampled, then press the bottom of the straight cylinder 1 against the target ground. Then step on the pedal 3 to fix the position of the straight cylinder 1, and then press down the semi-circular plate 6 to insert the long shovel into the soil. After the long shovel is inserted to the specified depth, lift the semi-circular plate 6 to pull out the long shovel, and then pull out the soil sample together. Then lift the device and push the long rod 8 through the circular push plate 9 to push out the soil sample. The staff can then take away the soil sample. If the soil is too hard and the long shovel 5 cannot be inserted, separate the two semi-circular plates 6, and then tap the locking blocks 7 one by one to drive each long shovel 5 into the soil to the specified depth. After all the long shovel 5 are in place, reassemble the semi-circular plates 6, re-clamp each locking block 7, and then pull upwards to pull out the soil sample.
